Understanding Media by M. McLuchan


Abstract

Marshall McLuhan’s book argues that media are not neutral tools. Each medium changes how people perceive, think, and live together, so the form of the medium matters more than the specific content it carries. His best-known claim, “the medium is the message,” means that the real impact of any technology lies in the way it reshapes human experience.

Context

Marshall McLuhan (1911-1980) coined the phrase “the medium is the message” in the early 1960s and popularised it in Understanding Media, the extensions of man (1964), at a moment when television, telephony, and other electronic media were rapidly expanding. The technological shift away from print’s sequential, visually dominated culture toward electrically mediated, simultaneous forms of communication framed his claim. His hypothesis is that new media reconfigure how people perceive time, space, and social relations regardless of the specific programs or content they carry.

Harold Innis (1894-1952) significantly shaped Marshall McLuhan’s thinking by providing the foundational premise that communication media are central forces in the organisation and development of societies. Innis’s historical and economic studies emphasised how the control, transmission, and monopoly of information affected empire, governance, and cultural continuity. McLuhan adopted this macro-historical perspective but shifted the focus from institutional power to perceptual and sensory effects, arguing that media themselves restructure human experience. 

Innis’s distinction between time-biased and space-biased media directly fed McLuhan’s analyses. Innis stressed how durable, tradition-preserving media (time-biased) differ from expansive, administratively efficient media (space-biased), and McLuhan used that contrast to explore how different technologies reconfigure senses, social scale, and patterns of attention. While Innis probed media bias as an economic and institutional force, McLuhan translated the idea into a broader sensory grammar of media, seeing each medium as privileging certain human activities and modes of perception.

Methodologically, Innis’s interdisciplinary, historically grounded approach, combining economic history, communication, and cultural analysis, gave McLuhan a model for wide-ranging, cross-disciplinary inquiry. McLuhan kept Innis’s conviction that media are not neutral instruments but agents with unintended consequences. However, McLuhan moved toward more aphoristic, literary, and perceptual formulations, popularising the insight with memorable phrases like “the medium is the message.” Together, Innis supplied the structural, institutional lens and McLuhan recast those insights into an influential theory of media effects and human sensibility.

McLuhan’s aphorism provoked strong interest across academia, advertising, and public life because it redirected attention from message content to medium-driven change: television’s immediacy alters political discourse; the telephone collapses distances; and networked electronics create new forms of collective awareness. Critics, however, faulted McLuhan for poetic overstatement and lack of empirical grounding, arguing he sometimes downplayed the role of content, social power, and economic structures that condition media effects.

Despite critiques, the idea remains influential for analysing contemporary digital platforms. Applied today, “the medium is the message” highlights how affordances such as algorithms, persistence, notifications, and network architectures shape attention, social organisation, and institutional practices independently of any single post or headline, showing the continuing value of McLuhan’s focus on form as causal in cultural change.

Summary

PART 1

Introduction

Marshall McLuhan opens by arguing that media are extensions of human senses and faculties: clothes extend the skin, the wheel extends the foot, and electronic media extend central nervous system functions. He emphasises that technologies change the scale and pattern of human association and perception more than they serve simple content functions. The medium’s characteristics shape social organisation and individual experience regardless of the messages transmitted.

McLuhan introduces the key distinction between “hot” and “cool” media: hot media supply abundant detail and require less audience participation (e.g., radio, film), while cool media provide less data and demand more active engagement from users (e.g., telephone, comic strips). This taxonomy helps explain how different media involve different kinds of sensory involvement and social consequences.

He stresses the importance of studying media effects, not just their content, because content is often a distraction from the intrinsic effects of the medium itself. McLuhan warns that people judge new media by the old — interpreting innovations through prior media frameworks — which obscures the structural changes each medium introduces to perception, attention, and social life.

Finally, McLuhan frames the modern electric age as creating a “global village” where electronic media collapse time and space, retribalising individuals into intensified collective involvement. He suggests that awareness of media as extensions can help society manage the unintended consequences of technological change.

1 The Medium is the Message

"The medium is the message." means that the consequences of any medium, essentially an extension of ourselves, stem from the scale introduced by each new technology. For instance, automation might eliminate jobs but simultaneously creates deeper roles for individuals, enhancing human connections lost by earlier mechanical technologies.

A core idea is that the "content" of any medium is primarily another medium. For example, the electric light acts as pure information unless utilised for specific purposes. The essence of understanding media lies in recognising how they transform human relationships and actions regardless of their specific uses. Each medium affects the scale and nature of human interactions.

Technological advances such as the railway and airplane highlight how mediums enhance or change human functions. The railway accelerates movement and creates new forms of cities and work, while the airplane alters previous forms of organisation and association, both demonstrating that the medium itself holds the transformative power, not just its content.

The electric light epitomises how a medium's true influence is often overlooked due to its lack of explicit "content." Its role in shaping human activity and interactions is paramount, as it allows for developments across various fields, from surgery to sports. Only when it serves a content purpose, such as advertising, do we start to acknowledge it as a medium.

The historical perspective on media also emphasises the need for awareness about their impact. Prominent figures like Shakespeare have touched on the transformative qualities of new media in their works, indicating that changes in perception are fundamental in understanding technological advancements.

The discussion further extends to the effects of media on political and social structures, as indicated by figures like de Tocqueville. Media change societal behaviours and norms, contributing to different levels of individualism and nationalism, contrasting oral and literate cultures.

Modern technologies have created a landscape where confusion between the medium and its content is prevalent. This disconnect can lead to a failure to recognize the genuine influence media have on culture and personal relations. The essential challenge is to transcend the "Narcissus trance" where society becomes fixated on the superficiality of media content rather than understanding the deeper implications of the media itself.

As the interplay between media and human experience evolves, it remains critical to analyse the inherent characteristics of each medium as a powerful agent of change. Such understanding not only informs personal engagement with media but also shapes collective consciousness in a society increasingly dominated by technological interfaces.

2 Media Hot and Cold

The discussion introduces the concept of hot and cool media: hot media provide high-definition, sensory-rich experiences with low audience participation, whereas cool media are low-definition and require more engagement from the audience.

Hot media includes forms like photography, radio, and film, providing extensive information but limiting audience participation. Cool media, such as the telephone and speech, provide minimal information and demand active engagement. The implications of these differences are crucial in various contexts, from dance to writing, shaping cultural expressions and societal interactions.

Hot technologies can disrupt established cultures, as seen when indigenous Australian societies crumbled with the introduction of steel axes, highlighting rapid societal changes. The movement from individualism back to corporate forms indicates the dual nature of media, where heating up can lead to both fragmentation and re-tribalization.

Contrasts between thinkers like Newton and Blake exemplify the challenge of mechanised thinking versus organic myth. The development of electric technology further disturbs society, as changes in communication methods compound existing social structures and necessitate frameworks for understanding modern experiences.

As societies evolve with technology, backward cultures that still maintain traditional oral communication cope better with new electric media than industrialized ones. The hot media climate of America begins to embrace a cooler, more engaging form of culture, turning conventional notions of entertainment upside down.

The text elucidates the change from message-focused communication to an emphasis on total effect, changing how we interpret meaning in media. It voices concerns about the emotional and psychological impacts of hot media, such as increased desensitization or fatigue, and stresses the need for a balance between hot and cool media in cultural expressions.

Different forms of media engage audiences variously, as shown in detective stories or TV shows, where the absence of complete information invites active participation. Practical jokes exemplify how physical engagement contrasts with hot literary media.

The enduring theme remains the need to balance cooling elements in hot situations, with humour and participation acting as necessary solvents for the intensity of modern life. Understanding the dynamics between hot and cool media effects is fundamental to navigating the complexity of contemporary society and personal interactions..

Critical interpretations of McLuhan's division of media into 'hot' and 'cool' categories stress the varying degrees of audience participation and emotional engagement across different forms of media. However, this dichotomy may not fully account for the complexities and nuances of how individuals interact with media based on their backgrounds, personal experiences, and sociocultural contexts. 

Critics like Neil Postman in Amusing Ourselves to Death suggest that the simplistic classification overlooks the multifaceted nature of media interactions, which often do not fit neatly into 'hot' or 'cool.' Therefore, while McLuhan’s insights are invaluable in understanding media effects and societal changes, readers should approach his conclusions with a critical lens, acknowledging that media's impact is more interconnected and complicated than his binary framework implies.

3 Reversal of the Overheated Medium 

On June 21st., 1963, an agreement was made to establish a direct communication link between Washington and Moscow, referred to as the "hotline." This decision to use teleprinter technology over telephone communication highlights differing cultural biases between the West and Russia. The choice of printed medium over oral communication reflects Western preferences and leads to misunderstandings. Differences in communication styles stem from cultural traditions, influencing how each side perceives and interacts with messages.

The chapter discusses a principle where systems evolve in patterns opposite to their initial forms, leading to a transformation in society's values and relationships. Historical observations, including Alexander Pope's reflections and children's perspectives, underscore this idea.

Media alternate between extremes: a medium’s dominant bias (speed, intensity, sensory focus) can intensify until it becomes “overheated,” producing distortions in perception and social life. Overheating amplifies particular cognitive or sensory modes, such as linear, print-based reasoning or instantaneous electronic communication, and creates social tensions like fragmentation, attention collapse, or institutional strain.

Those tensions generate demand for balance, prompting a shift or resurgence of media and practices that emphasise opposite qualities (slower, more reflective, communal), producing a reversal in the media environment. Reversals may occur abruptly or gradually and often become institutionalised through changes in education, law, politics, and cultural norms that either curb or harness the overheated effects.

Historical cycles of hot and cool media demonstrate predictable cultural consequences — changes in attention, memory, authority, and social cohesion — showing that media are active shapers of perception rather than neutral tools. McLuhan presents reversal as a structural, recurring mechanism in media ecology. Recognising these dynamics helps explain technological adoption, cultural backlash, and which practices are likely to gain traction as corrective responses.

4 The Gadget Lover: Narcissus as Narcosis

The myth of Narcissus illustrates the human tendency to become fascinated with extensions of oneself, leading to a state of numbness or narcosis. Narcissus, enamored by his reflection, became a closed system, highlighting a psychological and physical response to self-perception and tech. Narcissus did not realise that the image he loved was merely an extension of himself. This misinterpretation reflects a broader cultural misunderstanding, where individuals believe they fall in love with themselves, rather than recognising their image as a detached representation.

Research by medical experts like Hans Selye and Adolphe Jonas suggests that our extensions (technological or otherwise) serve to maintain equilibrium. Such extensions can lead to a state of “autoamputation,” where the system detaches from the source of irritation to protect the central nervous system. Extensions like the wheel emerge as responses to increased burdens in society. These inventions often lead to a new level of intensity but may require a degree of numbness in our perceptions to be tolerable.

The introduction of electric technology further amplifies this phenomenon. It suggests an urgent need for autoamputation as physical organs become overwhelmed by a fast-paced, mechanised environment. The evolved social experience creates a trauma that leads to generalised numbness. Experiences of both physical and emotional trauma produce similar shock responses, leading to diminished sensitivity to stimuli. Technological advancements often capitalise on this biological response, such as using sound to numb pain during dental work. Increased specialisation of one sense through technology results in a corresponding decrease in sensitivity of others. Different cultures respond uniquely to technological changes based on their existing sensory ratios, illustrated through media influences like television.

McLuhan parallels the narrative of Narcissus to the Biblical concept of idols, suggesting that humanity increasingly conforms to the technologies it creates. These idols, while serving practical functions, also lead to a fragmentation of perception and identity. Technologies are self-amputations that create closed systems, often resulting in heightened conflict due to extreme intensities of experience. This self-amputation can lead to both social unrest and technological innovation.

The accumulation of social pressures, particularly from war, drives innovation. After conflicts, societies adapt their sensory perceptions, leading to technological evolution and hybrid cultural exchanges. With electric media, we experience profound numbness in our central nervous system. The resulting anxiety reflects a newfound consciousness of technology, transforming our relationship with it and revealing deeper social consciousness. As we navigate the electric age, our awareness of technology as an extension of ourselves increases. This awareness fosters a broader social consciousness, compelling a shift from individualism to collective involvement in societal structures.

5 Hybrid Energy: Les Liaisons Dangereuses

The ongoing conflict in art and entertainment, characterised by the emergence of various media forms, profoundly affects our psychic lives as they extend and amplify our being. The interactions among different media can be viewed as a civil war within society and our minds.

Media serve as agents that "make happen" but not necessarily "make aware." The hybridisation of media allows us to recognise their structural components and the roles they play in societal evolution. Historical observations have shown how specific media pathways cry out for the emergence and integration of new forms.

The intersection of literate and oral cultures creates a dramatic release of energy, marking significant social and political transformations. The fusion of these different cultural practices, particularly in regions recently adopting literacy, can lead to unprecedented levels of human power and potential conflict.

The electric age is characterised by an implosive merging of cultures, leading to complex changes in emotional and social dynamics among individuals who have experienced different modes of society. This shift redefines the nature of individuality within an interdependent, electrically-influenced cultural framework.

Facing the realities of this new interdependence poses challenges for individuals emerged from a fragmented, literate society. Recognising these shifts and clarifying their implications can ease the burden of adaptation as societies evolve.

The integration of different media forms alters societal structures and daily experiences. For instance, jet travel affects operations in governmental organisations like the Pentagon, symbolising the rapid change that results from hybrid media. The power of electric light and information technologies further transforms existing societal patterns and human interactions. Artists and creators adapt new media forms to release their potential, resulting in unprecedented combinations of expressions across genres.

The mixing of media becomes essential, as seen in literature and theatre, which influences how stories and experiences are shared and how cultural dynamics evolve. Cultural hybrids emerge through interactions between various media, reflecting the organic development of new expressions and relationships.

This dynamic illustrates how media can reveal the potential of new forms while facilitating understanding across varied cultures and practices. The hybridisation of media represents moments of truth and revelation, offering opportunities for innovation and freedom from established norms. Recognising these intersections enables individuals to break free from the conventional narcosis imposed by existing media, fostering new realms of creativity and expression.

6 Media as Translators

The translation of knowledge through technology is a central theme in McLuhan's work. Neurotic behaviours in children, such as stuttering disappearing when speaking in foreign languages, illustrate how technologies can alter experiences and perceptions. Lyman Bryson's notion that "technology is explicitness" embodies this idea, highlighting how mechanisation serves as a translation of nature and human experience into amplified forms.

All forms of media act as metaphors, transforming and translating experiences into new expressions. The spoken word, as humanity's first technology, allows for the retrieval of knowledge and experience at high speed. The electric age enhances this capacity, enabling human expression to be transformed and stored in ways that extend far beyond traditional forms.

In the context of electric technology, human existence becomes centered around learning and knowing, blurring the lines between economy and information flow. This transformation leads to a situation where all employment may become a form of "paid learning," reflecting a shift from tangible goods to the circulation of information. McLuhan references Shakespeare's "As You Like It" as an exploration of applied knowledge and the transformation of nature into art. The forest of Arden serves as a metaphor for a world where skills and knowledge can be programmed and translated across different domains.

7 Challenge and Collapse: the Nemesis of Creativity

In this chapter, McLuhan examines the dual nature of creativity and technology, referencing thinkers such as Bertrand Russell and A. N. Whitehead. He contrasts the "technique of suspended judgment," which allows anticipation of effects and preemptive adjustments, with the numbing effects of new technologies that impede perception and judgment.

McLuhan discusses how technological changes not only reshape daily habits but also transform thought and value structures, citing a parable about a gardener who resists mechanisation for fear of losing simplicity. The artist's role is emphasised as essential in navigating these technological impacts, providing foresight, and adapting to inevitable societal changes.

The chapter highlights how artists can forecast the psychic consequences of technological change, acting as a cultural conscience by helping society adjust to the complexities of new media. Emphasising that history has largely neglected needed adjustments to technological extensions, McLuhan argues that artists should be integrated into societal discussions to better navigate and mitigate these impacts.

Observing historical responses to technological shifts, McLuhan connects the fragmentation of knowledge and specialisation to societal collapse under new pressures. He critiques the resulting disconnect between past and present and encourages a broader perspective that includes learning from what artists can teach about future challenges.

McLuhan references Toynbee, who outlines culture’s strategies for facing challenges and adapting. As societies encounter new technologies, decentralisation and flexibility may serve as countermeasures rather than expansion or militarism, urging cultural adaptation instead of retreating to past paradigms.

The chapter underscores the urgency for society to recognise the transformative impact of technology on personal and collective consciousness. It posits that understanding the dynamics of these changes can lead to a more profound mastery of cultural and technological challenges instead of merely succumbing to their pressures.

PART II

8 The Spoken Word: Flower of Evil?

This chapter examines the nature and impact of the spoken word, illustrating its essence through examples of modern communication, such as a disk-jockey show. It highlights how the spoken word engages multiple senses, creating a lively interaction with the audience. In contrast, written language, shaped by literacy, fosters individualism and a sense of privacy, which can separate individuals from communal experiences.

The text contrasts the richness of spoken language with the limitations of written communication. Henri Bergson's perspective is introduced, suggesting that language, while extending human capabilities, also diminishes collective consciousness and emotional involvement. The spoken word is seen as an organic extension of human expression, linking the individual to a broader sensory experience.

Furthermore, it discusses the evolution of communication technologies and their implications for language. The advent of electric technology suggests a potential shift towards a collective awareness that bypasses traditional verbal communication, moving towards a universal understanding devoid of linguistic barriers. This evolution could lead to a state of harmony and unity among humanity, reminiscent of a pre-verbal condition, fostering a deeper connection with the collective unconscious.

As an example imagine attending a vibrant live concert where the artist's voice resonates through your body, each note eliciting a visceral response from the crowd. In that moment, you feel interconnected with everyone around you, sharing an experience that transcends individual thoughts and privacy. 

This starkly contrasts with reading a book alone. There, you may ponder the words in silence, yet the essence of shared feeling and community is lost. As McLuhan emphasises, the spoken word serves as a powerful medium that deeply engages multiple senses, igniting emotional connections and fostering a communal experience that written communication can never replicate.

9 The Written Word: an Eye for an Ear

The author opens chapter 9 by arguing that the written word is not simply a record of speech but a new sensory environment that privileges sight over hearing. Alphabetic writing and print reorganise human perception by segmenting continuous oral experience into discrete visual units — letters, words, lines — producing habits of linearity, analysis, and abstraction. This visual bias reshapes cognition: reading becomes a private, solitary act that fosters interiority, detached judgment, and the notion of the neutral observer.

McLuhan traces historical effects of literacy and print on social institutions and thought. The alphabet enabled categorisation, record-keeping, and bureaucratic administration; the printing press amplified uniform viewpoints, stabilised language, and helped form public opinion and nationalism. These changes encouraged scientific, legal, and administrative systems built on segmented, sequential reasoning, while diminishing oral mnemonic techniques and communal participatory practices.

He emphasises a sensory balance concept: media alter the ratio of the senses. As sight strengthens under literate regimes, hearing and oral modes atrophy, producing cultural losses even as new capacities arise. McLuhan sees this as paradoxical and cyclical. Each medium both suppresses and sets conditions for later media to restore suppressed senses. Thus the written word’s dominance creates the environment that later electronic media would challenge by reintegrating auditory and participatory forms.

Ultimately McLuhan’s point is that the form of the written word — its technology and environment — shapes thought, social organisation, and perception more profoundly than the specific content conveyed. Literacy’s visual orientation promotes fragmentation, abstraction and individualism, transforming how societies remember, reason, and relate.

10 Roads and Paper Routes

The telegraph revolutionised communication, allowing messages to travel faster than physical messengers. This milestone marked a shift where information became separate from tangible mediums like stone or papyrus, paralleling the historical shift of money from physical forms to paper. The conventional understanding of "communication" evolved from transportation-related terms to "information movement" in the electric age.

Transport serves as a metaphor for carrying goods and information, affecting the sender, the receiver, and the message itself. The introduction of new technologies alters interpersonal dynamics, increasing both power and speed, which subsequently causes changes in social organization and community structures.

Speed advances result in a centralised organisation, as seen with the formation of the Roman Empire. Increased speed from paper messages and improved road transport led to greater control over vast distances. As communication technologies improved, they caused disruptions by separating functions and causing societal breakdowns, illustrated through the history of civilisations and empires.

Empires often centralise power as they expand, leading to tensions when peripheral areas seek independence. The dynamics of land versus sea powers reflect this: land-based powers can maintain a centralised structure, while sea powers create multiple centers. This center-periphery tension continues to manifest, with electric speeds erasing margins and establishing centers worldwide.

Differentiation in information speeds leads to diverse social patterns. Rapid communication enhances the potential for political unity, while discrepancies in speed can cause organisational conflicts, evident in contemporary cities. The homogenisation of speed through print media allowed better political coherence, contrasting with earlier forms of communication.

Technological advancements, especially in transport and communication, have consistently favored centralisation. The alphabet and paper introduced a need for literate training among workers, ultimately leading to centralised power through standardised education. As empire-building accelerated, a conflict emerged between traditional authorities (like priests) and new political powers utilising communication technologies.

The city evolves from a protective community to one rife with competition and specialisation. While village life allowed for many roles, urbanisation divided functions and intensified societal competition, leading to aggressive expansion and further specialisation.

Rapid changes in transport have caused cities to grow while simultaneously disconnecting individuals from traditional rural landscapes. The advent of roadways, railways, and eventually airplanes disrupted prior social arrangements, with urban spaces becoming increasingly relevant due to the speed of modern travel.

The current shift toward an electronic age can lead to a reorganization of spatial awareness and social practices. As electric media amplify human functions beyond traditional limits, established societal structures may face obsolescence, necessitating new understandings of organisation and connection in an increasingly accelerated world.

11 Number: Profile of the Crowd

Hitler's condemnation of the Versailles Treaty stemmed from its impact on the German army, which had become a symbol of unity and strength. In contrast, in Britain and America, the idea of power was linked to industrial output and wealth, reflecting the mysterious dynamic of sheer numbers.

Elias Canetti’s exploration of crowds and monetary inflation reveals the connection between crowd behaviour and economic growth, suggesting that both phenomena share a drive towards unlimited expansion. In mass gatherings, individuals experience joy from the collective presence, highlighting a socially suspect delight in numbers, contrary to the individualistic focus of Western culture bolstered by literacy. The printed word has historically contributed to a homogenised societal identity, eventually leading to concepts of a "mass mind" and mass military forces. 

While writing has been deemed foundational to civilisation, numbers, as an extension of our tactile sense, have also shaped perception, signaling a need for unity amidst growing fragmentation. Historically, numbers were viewed as magical extensions of the physical realm, embodying auditory and tactile dimensions. This quality makes numbers icons in journalism and social discourse.

The fascination with tribal culture among European intellectuals suggests a conflict between traditional values and modern visual culture, where numbers enjoy an almost mystical significance, encapsulated by phrases like "57 Varieties." Baudelaire captures this tactile essence of numbers, reflecting their role in fostering a crowd's joy in multiplicity.

Amidst the tension between rationality and the primal nature of numbers, assessments from ancient societies illustrate their unique relationships with counting and quantities, revealing cultural stages of complexity. Dantzig’s observations on the evolution of numeracy underscore an intrinsic connection between number systems and human experience that transcends mere literacy.

The rise of modern mathematics and its conceptual shifts challenge the visual-reliant Western thought process, leading to revelations about infinity and the abacus. The interplay of print media with numerical understanding showcases a technological transformation from tactile to visual modes of experience.

Spengler’s concerns regarding the implications of modern mathematics reflect trapped values that emerged from shifts toward abstract understanding, suggesting a holistic view where the evolution of all media retains a tactile root. Consequently, the dialogue between cultural paradigms and emerging technologies shapes our actual perceptions of numbers. Just as earlier civilisations grappled with encoding their physical realities into numerical abstractions, contemporary society undergoes a similar transition with digital and electric shifts, thrusting humanity back toward communal integrations that echo primal urges for connection and touch.

In essence, the exploration of numbers reveals a multifaceted relationship between human senses, societal developments, and the cultural grasp of abstraction, emphasising the importance of touch and community amidst the logical frameworks that dominate modern thinking. The quest for harmony between tactile existence and visual demands continues to be a defining characteristic of our evolution within technological domains.

12 Clothing: Our Extended Skin

Clothing acts as an extension of our skin, influencing both our energy needs and social interactions. Economists suggest that unclothed individuals consume up to 40% more food compared to those in Western attire.

The relationship between clothing and sex is complex, often serving as compensation for the lack of privacy found in crowded living situations, particularly in tribal societies. Clothing functions as a heat-control mechanism and a means of social identity, paralleling the role of housing.

As European styles shift to emphasise visual aesthetics, Americans are moving towards touch and participation, reflecting a shift from abstract visual culture to tactile engagement. This evolution mirrors historical consumer revolutions, where simple attire represented social integration and rebellion against the feudal system.

The current trends in women’s fashion reflect a move towards tactile and sculptural elements, prioritising a sense of touch over mere visual appeal. As Western societies embrace the idea of clothing as an extension of the body, the cultural perception of nudity shifts, revealing a deeper connection to tactile and sensory experiences that transcend visual norms. This shift signifies a broader awareness of sensory engagement, where textures and shapes in both clothing and architecture reflect a unified sensibility, celebrating creativity across multiple art forms.

13 Housing: New Look and New Outlook

Housing is viewed as a collective means to manage heat and energy for families, akin to clothing as an extension of skin. It functions as a collective skin, while cities further amplify this extension for larger groups. James Joyce's literary structure in Ulysses exemplifies the relationship between city forms and bodily organs, suggesting a unity of human experience across history. 

Tribal societies perceive their existence as part of a cosmic whole, where housing represents both the body and the universe. In contrast, literate civilisations compartmentalise space, losing their connection to cosmic patterns. This shift from round dwellings to square ones reflects the transition from nomadic to sedentary lifestyles and the specialisation of tasks.

Technological advancements have transformed housing and architectural design. Changes in heating and lighting have reshaped spatial dynamics, with electric energy allowing for increased flexibility in living and working spaces. This reflects a broader trend towards organic structures reminiscent of earlier cosmic connections inherent in tribal designs.

Electric lighting has revolutionised perceptions of space and domestic routines. Houses now function without traditional boundaries of day and night, enhancing productivity and creativity. Light, both as a medium and a form of information, alters how humans engage with their environments, leading to a deeper understanding of perception.

As technological progress continues, there may emerge new forms of housing that challenge the traditional concept of walls and boundaries. Innovations such as the laser ray suggest that future architecture might evolve beyond mere physical structures, potentially leading to a collective consciousness without traditional language barriers.

14 Money: the Poor Man's Credit Card

The intersection between money and human psychological development is a central theme in modern psychoanalysis. Some theorists equate money with "odorless dehydrated filth." 

The history of money begins in nonliterate cultures with the use of commodities for barter, such as whale teeth or rats, evolving into different systems based on community needs during crises. In contemporary literate societies, money's evolution has allowed it to assume both commodity and community characteristics, impacting how trade extends from local to global levels.

Currency, a movement away from direct commodity exchange, represents a cycle of grasping and letting go akin to a trapeze artist's movements. The concept of money also parallels the development of language, while the communal acknowledgment of its value is necessary for its function, illustrated by the futility of Robinson Crusoe’s discovery of coins. 

Among primitive societies, money facilitated economic activities not solely for profit but often to bolster social status or prestige, evident in cultures where surplus goods are destroyed to maintain social hierarchy. As industrialisation evolved, so did the understanding of money from a mere store of value to a complex social medium that amplifies work and conveys societal functions, shaped by literacy and abstract thought.

The printed word fundamentally altered perceptions of money, leading to representative money that emphasises speed and abstraction over physical commodities. In the electronic age, the transition from tangible currency to credit technologies suggests an increased emphasis on information and knowledge rather than mere labour, transitioning societies towards a model where personal roles and inputs become intertwined with information gathering. 

Both money and language serve as fundamental tools for exchanging human experiences and skills, with each acting as a translator and storehouse of cultural knowledge. The evolution of money reflects significant sociocultural shifts, including the fragmentation of roles within society, linking the historical development of financial systems to broader technological advances. 

The modern monetary system, heavily reliant on information flow and automation, presents challenges for understanding wealth as it becomes increasingly detached from traditional measures of value. The dynamics of currency, where wealth can be rapidly accumulated or lost, echo the innate human anxieties around economic power, equality, and societal roles.

15 Clocks: the Scent of Time

McLuhan explores the profound impact of clocks on societal structure and individual perception of time. He discusses how the introduction of mechanical clocks shifted time from an organic experience to a uniform, quantified entity, often divorced from natural human rhythms.

While Western societies have embraced punctuality driven by mechanical clocks, non-literate cultures demonstrate a different relationship with time, often measured by natural phenomena rather than uniform units. The mechanisation of time began with medieval monasteries, evolving communal and labour practices around clock time rather than organic needs.

McLuhan contrasts the mechanical measurement of time with time defined by sensory experiences, particularly the sense of smell, which historically tied individuals to memories and community. Highly literate societies often suppress odors to maintain detachment, demonstrating a shift away from communal, cohesive values of time measurement. McLuhan asserts that literacy, especially phonetic literacy, enabled the abstraction of time, which transformed life’s rhythms.

The emergence of clocks created not only a new social structure but also facilitated an economic framework where uniformity replaced individuality.

16 The Print: How to Dig it

The ability to create precise pictorial statements through print has been a crucial part of Western development, underpinning modern sciences and technologies. Historical comparisons highlight the secretive nature of early mapmaking, which shares similarities with today’s technological advancements and intellectual property.

Early maps functioned as records of exploration and experiences, lacking the uniform spatial perceptions that emerged later because there is a disconnect between historical and contemporary understandings of space.

McLuhan discusses how words fail to effectively convey visual information, hindering the development of early sciences like botany. The reduction of spoken language to visual forms in literate cultures has necessitated a reliance on visual media for accurate representation.

Long before Gutenberg’s printing press, woodcut printing was widespread, producing popular texts like the Biblia Pauperum. This early form of print highlighted that more copies often led to fewer surviving artifacts, demonstrating the law of bibliography.

In medieval and Renaissance periods, various art forms were intertwined, and reading was a communal activity. Techniques in manuscript illumination reflected a tactile and sculptural quality that resonates in modern graphic arts. The defining feature of print is its capacity for repeatability, which transformed the production of information. The innovation of movable type mechanised knowledge-transfer, emphasising visual components over other sensory experiences.

Print was embraced as a means for communication and contemplation, evident in texts like The Art of War. The limited information provided by prints required active viewer interpretation akin to modern visual media such as television.

The shift towards automation and technological advancement became necessary as labour supplies dwindled. This raised questions about the implications for the human workforce and how it relates to leisure, dignity, and involvement.

The limitations of language in accurately defining concepts, as reflected in Descartes’ philosophical pursuits, led to a fragmentation of knowledge. The precision of visual information revolutionised perspectives and influenced artistic representations.

Artists like Hieronymus Bosch captured the tension between medieval disjointedness and Renaissance uniformity. Lewis Carroll's work, in contrast, navigated themes of continuous and discontinuous time, preparing readers for modern conceptualisations of space.

Contemporary examples reveal that individuals from non-Western cultural backgrounds can struggle with modern spatial concepts. The struggles of indigenous communities in adapting to new mediums highlight the challenges of translating traditional practices into contemporary frameworks.

The transition from low-definition medieval art to a high-definition perception altered how objects interact within space. Einstein's theories contributed to the dissolution of fixed perceptions of space, paving the way for modern artistic expressions and frameworks.

17 Comics: Mad Vestibule to TV

In this chapter, McLuhan discusses the evolution of comics and their relationship to print and television. He notes that comics historically draw from print, with their crude woodcut characteristics allowing for a participational experience. This connection is significant since the viewer's interaction with television images mirrors the low-definition and participatory nature of comics.

McLuhan highlights the impact of comics on American culture, particularly through notable works like Richard F. Outcault's "Yellow Kid" and Al Capp's "Li'l Abner." He observes that TV transformed how audiences engage with media, compelling creators to adapt. Capp's humour, rooted in the absurdities of life, struggled as TV's cool medium demanded deeper involvement, revealing Americans' shifting preferences towards comedy reflective of everyday experiences.

With the rise of TV, magazines like MAD emerged, representing a shift in popular culture from traditional comics to forms that resonated better with contemporary society. MAD magazine's playful critiques of media reflected the changing dynamics in American culture, signaling a transition from a consumer-oriented age to one emphasising depth and participation. McLuhan concludes that the evolution of comics, along with other forms of popular art, illustrates a fundamental shift in societal engagement with media.

As America became Europeanised, the older comics lost relevance, giving way to new forms of expression that align with the complexities of modern life. The chapter emphasises that understanding these visual forms requires recognising their capacity to reflect and influence consumer culture through their unique portrayal of experiences.

18 The Printed Word: Architect of Nationalism

This exploration of the printed word highlights the significance of typography as a revolutionary mechanization of communication. Printing from movable types served as a catalyst for an expansive dialogue among individuals across different ages and cultures, dismantling the barriers of parochialism and tribalism. The initial motivations for the widespread adoption of printing were not solely to create new texts but largely to revive ancient ones, marking a shift in human interaction and understanding through the democratisation of knowledge. This “printed book” blended ancient wisdom with contemporary thought, paving the way for a modern worldview. 

The arrival of electric technology signals is another transformative phase. As print broadened human communication, electric media may create a renewed sense of tribalism as information becomes instantaneously accessible. 

Despite the rich history of the printed word, explicit awareness of its effects on individual and collective psyche has been limited. Print transformed communication and intellectual engagement, influencing cultural forms and the prominence of individual perspectives. The typographic extension of man led to significant societal changes, including nationalism, industrialisation, and universal literacy. 

The clarity and precision of printed text fostered new social energies, breaking individuals from traditional community confines into larger collectives. The printed word's capacity to foster detachment and independence from immediate communal relations was both empowering and disorienting. This special quality, tied to the identity of literate individuals, has been observed as increasingly problematic in the electric age, where interconnectedness is the norm. Printing replaced archaic educational paradigms, enabling uniform processes and enhancing accessibility.

19 Wheel, Bicycle, and Airplane

Lynn White's insights into how technologies like the wheel, stirrup and horse-collar transformed social structures highlight the interconnectedness of technological advancement. His work illustrates that the lever of the wheel not only revolutionised transport and agriculture but also reshaped feudal systems and societal classes.

The evolution of transportation modes, from horse-drawn vehicles to automobiles and airplanes, catalysed urban development. The wheel enabled heavy cartage and urban living patterns, while changes in transportation led to the rise of suburbs, fundamentally altering how humans inhabit and interact with spaces.

Technological advancements like the bicycle and movie camera derive from the wheel's development. Each new technology amplifies human capabilities and creates new societal dynamics that both reflect and shape human nature. This interplay emphasises that technology is an extension of the physical human form, altering our functions and relationships.

Beckett's symbolism of the bicycle as a representation of human futility in a specialised society reveals the dichotomy between skilled specialisation and integral human being. The concept of Humpty-Dumpty underscores societal fragmentation and loss of unity, prompting a search for reconciliation in a technologically advanced world.

The wheel's role in creating centralised urban structures exemplifies explosive growth through the acceleration of transport and communication. This centralisation has led to agglomeration and specialisation, building a complex social fabric where the effects of technology continually reshape human interactions.

The shift to electric and fast-paced technologies, such as airplanes, signals a reversal of centralism, fostering decentralisation and more fluid social interactions. This transformation reflects a broader move towards interconnectedness and interaction outside of rigid social frameworks.

The historical narrative explored the duality of forces creating and regulating power structures, stressing that while technology promotes fragmentation, it also enables the possibility of reestablishing harmony as societies grapple with new pressures and potentials in an electronic age.

Cities and institutions throughout history manifest humanity's complexity and diversity. As technological advancements continue to evolve, they shape human expressions and guide the reformation of sociocultural identities, reflecting a continuum of civilisation's expansion and integration.

20 The Photograph: the Brothel-without-Walls

Photography isolates moments in time, creating a distinct impact compared to the continuous images provided by television. While a photograph like "St. Peter’s at a Moment of History" captures a fleeting moment, TV presents a more dynamic and connected representation.

Traditional art forms like sculpture tend to depict timelessness, while photography can commoditise the human experience, transforming individuals into objects, often leading to societal discomfort with mass-produced images.

This phenomenon, illustrated in works like Genet’s "The Balcony," reflects a deeper truth about society and the lasting influence of photography in shaping perceptions of reality. Photography not only challenges individualism but also represents a collective experience, unlike print technologies that support personal reading and writing.

Historical connections between prints and photography underscore how visual syntax evolved, paving the way for modern photographic methods. The early adaptations of photography built upon existing tools like the camera obscura and pushed boundaries of visual representation, though they also created new forms of misinformation and illusion within media.

As photography evolved, it transformed creative industries, prompting artists and writers to shift from merely depicting external realities to exploring internal processes and human consciousness. This shift highlights the move from mechanical to electric ages, where the medium influences interactions and perceptions profoundly.

Education remains essential as people navigate this complex media landscape characterised by accelerated change and the rise of new "pseudo-events." The dominance of visual media has altered relationships, personal postures, and societal awareness, dictating the way travel and consumption of culture occur.

The ease of movement via media contrasts with the deeper, more meaningful experiences of travel in past centuries. Many modern encounters with places are like packaged experiences shaped by prior media exposure rather than genuine exploration.

The instantaneous nature of photos and visual media creates superficial engagements that reflect societal values back to individuals. Ultimately, to understand the impacts of photography and related technologies, one must recognise their interplay with other media.

These extensions of human perception affect how society views itself and processes experiences, emphasising a need to critically engage with media rather than passively consume it.

21 Press: Government by News Leak 

As electric speed transforms societal decision-making, it shifts away from traditional representation toward immediate community involvement. This change disrupts older media practices, which relied on slower information exchange and delegation.

The press, unlike books, acts as a communal medium, presenting multiple viewpoints through a mosaic format. This format fosters engagement, turning readers into participants rather than passive observers, particularly influenced by the advent of television.

TV has uniquely altered the popularity of news magazines like Time and Newsweek, which utilize a mosaic format that resonates with the participatory nature of modern media. This shift underscores how the press delivers community narratives and the interplay of good and bad news.

Books and newspapers both serve as confessional formats but differ markedly in their functions. Books offer private introspections, while newspapers reveal communal interactions, often highlighting the less favorable aspects of society.

Advertising plays a critical role in sustaining newspapers. While some criticise press frivolity, ads engage readers and enhance their experience, often providing more creativity and insight than accompanying news articles.

22 Motorcar: the Mechanical Bride

The automobile serves as a crucial aspect of American identity, symbolising status and self-expression. It creates a sense of uncertainty and incompleteness when absent from urban life. While some argue that the house has taken over as the primary status symbol, the car still plays a significant role in American society, redefining social interactions and the urban landscape.

As towns adapt to reclaim pedestrian-friendly spaces from car-centric designs, the narrative shifts towards potential technological transformations.Future innovations, such as shopping through television, may fundamentally alter consumers' relationships with work and shopping, moving away from traditional forms.

Historically, the horse served as a primary means of transportation, yet it has become largely symbolic today, much like how the automobile might evolve into a form of entertainment rather than transportation. The car's future lies not in its traditional use but rather in a potential obsolescence brought about by new electric technologies.

Television has fundamentally challenged the uniformity represented by the automobile, prompting a cultural critique of mass-produced goods. Whereas the car once played a pivotal role in creating social equality by normalising distance and mobility, its significance has shifted in light of new media influences, which diminish the overwhelming emotional responses historically associated with automobiles.

The portrayal of cars in media, particularly during the silent film era, underscores the dichotomy between fantasy and reality.This relationship further complicates the automobile's status as a mere status symbol. Critics have begun to question the cultural legacy of the car, hinting that it may create more conformity than individuality in American society.

As Americans confront the car's legacy and its implications for social structures, the notion of status tied to automobile ownership comes under scrutiny. The rise of automation suggests an impending transformation in marketing and product distribution, implying a move away from uniformity that has long defined American consumer culture.

The motorcar has reshaped social spaces and interactions, becoming a protective shell for urban and suburban individuals. While it continues to influence daily life, the time frame of its dominance is limited. As we approach an electric era, the car's role and significance are likely to shift dramatically, ushering in new forms of communication and social organisation.

23 Ads: Keeping Upset with the Joneses

Advertising increasingly mimics audience desires rather than focusing solely on the products. The audience's experience becomes integral to the advertisement, leading to a unified representation of product and public response. This shift reflects significant changes in advertising philosophy, wherein commercial success derives from understanding community consciousness and participation.

The trend in advertising is moving towards iconic imagery, integrating consumer and producer images into a single complex representation. This move undermines traditional media, particularly pictorial magazines, as consumers gravitate towards advertising that encapsulates broader social processes rather than fragmented news.

The rise of television has introduced a mosaic form of presentation, inviting deeper audience participation and reflecting community activities. Advertisements operate on principles reminiscent of brainwashing, subtly influencing subconscious thoughts and societal norms.

Concerns about the advertising industry arise as it appears to automate cultural processes, seeking harmony across human aspirations. However, the television medium necessitates heightened awareness of the unconscious, leading to shifts in consumer engagement and advertising techniques.

The analysis of advertising extends beyond American borders, where cultural differences affect consumer behaviour and political awareness. The shift towards commodification suggests that societal homogeneity is essential for promoting goods and services effectively.

The evolution of advertising reflects a shift from typographic literacy to visual representation in media. The advent of photography and television changed the landscape, influencing how audiences perceive and interact with advertisements.

Humour plays a crucial role in the reception of advertisements, as they tend to evoke laughter when critically examined. Nonetheless, advertisements are crafted for subliminal impact, targeting the subconscious while operating outside the scrutiny of critical analysis.

Ads serve as a complex cultural artifact, indicating societal trends, norms, and collective experiences. Rather than merely prompting consumption, they offer commentary on the social landscape and engage audiences in unique ways.

Overall, advertising continues to evolve, adapting to contemporary modes of participation and cultural representation. Its ability to synthesise consumer experience with product promotion exemplifies its significance in shaping societal values and norms, embedding itself deeply into the fabric of modern culture.

24 Games: the Extensions of Man

Alcohol and gambling hold diverse meanings across cultures. In the Western context, alcohol serves as a social bond, while it disrupts social patterns in tribal societies. Conversely, gambling represents individual initiative in tribal cultures, but poses threats to individualism in modern societies. The Prohibition era reflected a recognition of alcohol's dangers to individualistic social structures. The potential legalisation of gambling could signify a return to tribal social structures.

Games represent collective responses to cultural dynamics, showcasing both actions and reactions of groups. They serve as metaphors for psychological states, offering a release from daily pressures. Historical anecdotes illustrate how games and literature can foster community connections and divert attention from serious realities.

Games provide insight into a culture’s values and structures. They establish a means for non‑specialised participation, acting as a sanctuary for individuals against society's monotonous routines. Without games, individuals risk falling into a conformist trance. Society's transition from conventional structures to sporting competitions reflects both its unity and diversity.

As cultures evolve, so do their games. Traditional games like baseball are losing relevance, while non‑positional sports like basketball and soccer gain prominence, emphasising continuous play, spectator engagement, and adaptable roles that mirror modern social dynamics.

25 Telegraph: the Social Hormone

The wireless telegraph gained prominence in 1910 during the arrest of Dr. Hawley H. Crippen, who had murdered his wife and escaped abroad. The case highlighted how electric media, like the telegraph, transform organisational structures by facilitating instant communication and eroding traditional hierarchies. This shift leads to a more interconnected society, as electric media establishes organic interdependence among institutions, akin to biological systems regulated by hormones.

Electric media fundamentally alter human interaction, promoting a collective awareness that transcends individual experiences. Unlike mechanical technology, which segments tasks, electric communication fosters an integrated approach. J. Z. Young's insights into brain function illustrate how interconnected electrical systems enhance human interaction with the world, challenging the mechanised separation of previous ages.

The shift to an electric age prompted artists to explore tactile and sensory qualities in their work. Techniques from painting to poetry sought to unify experiences rather than remain fragmented, emphasising the holistic nature of perception in the electric era.

The telegraph, initially dependent on rail and newspaper networks, quickly evolved into a pivotal communication tool, establishing its own significance by the mid-19th century. Samuel Morse’s initial telegraph line marked a technological revolution that blurred traditional hierarchies and promoted rapid, decentralised information dissemination.

As the telegraph revolutionised news gathering and reporting, it fostered a new "human interest" aspect in journalism, as exemplified by Florence Nightingale's efforts during the Crimean War. The telegraph conveyed real-time accounts of human suffering, shifting public engagement from abstract reporting to immediate emotional participation.

The telegraph transformed the structure of the press by decentralising information flow and diminishing the influence of editorial opinions. This change led to a more competitive landscape, as regional presses gained independence and influence due to instant communications, ultimately reshaping the literary landscape of America and Europe.

The telegraph’s influence extended to various areas, including the emergence of weather forecasts as an engaging topic for the public. The ability to track and report meteorological changes exemplified how electric communication enhanced participatory experiences, moving beyond mere observation.

26 The Typewriter: into the Age of the Iron Whim

The chapter discusses the profound social impact of the typewriter, beginning with Robert Lincoln O'Brien's observations from 1904. The typewriter fostered the dictating habit and altered communication dynamics, influencing how speakers engage with their audience through gestures even in written forms. Historically, typewriters were initially marketed as educational tools but soon transformed into essential devices in business and creative writing. 

Authors like Charles Olson celebrate the typewriter's ability to empower poets, claiming it gives them a musical quality akin to that of a musician. The emergence of female typists in the 1890s brought about cultural changes and fashion influence, showcasing how the typewriter became a symbol of independence and professional identity. 

The typewriter also integrated functions that made it indispensable for organisations, evolving into a critical instrument in various sectors, including military operations. While the typewriter promoted standardisation in spelling and grammar, it also spurred huge increases in office paperwork and bureaucracy. Its adoption led to the realisation that communication within organisations is often more significant than the actual work produced, aligning with Parkinson's Law regarding staff accumulation in bureaucracies. 

The chapter concludes by reflecting on how the typewriter merged the roles of writing, composition, and publication, paving the way for a shift in how authors approach their craft. Ultimately, it underscores the irony that while the typewriter promised careers and independence, it also complicates the nature of work and achievement in a fast-paced, information-driven society.

27 The Telephone: Sounding Brass or Tinkling Symbol?

The chapter explores the cultural significance and effects of the telephone, citing early reactions to it as a medium lacking substance. It references influences from figures like Jack Paar and James Joyce, suggesting the telephone alters human connections through its extension of auditory capabilities.

The telephone has decentralised communication and transformed societal roles, illustrated through the evolution of prostitution from specialised practices in red-light districts to call-girl culture. The telephone's impact on women is highlighted as it reconnects them to the workforce, just as the typewriter initially removed them from the home.

The telephone demands a different kind of engagement compared to other media, compelling users to engage fully, which can be uncomfortable for those accustomed to fragmented attention. This challenges the literate Western idea of visual dominance, revealing a struggle in adapting to complete auditory engagement.

The chapter outlines the history of the telephone's development alongside innovations in communication technologies. It discusses the original intentions behind the creation of the telephone that sought to improve communication for the deaf and contrasts it with past inventions like Braille.

28 The Phonograph: the Toy that Shrank the National Chest

The phonograph, stemming from the technologies of the telegraph and telephone, primarily emerged in its electric form with the innovation of the tape recorder. Sound operates as a unified field of relationships, akin to electromagnetic waves, which led to the early association of phonographs with radio. John Philip Sousa noted the phonograph's potential to diminish individual vocal participation, paralleling how the automobile reduced pedestrian activity.

Initially perceived as a tool for auditory writing (with names like "gramophone" and "graphophone"), the phonograph was designed as a talking machine. Edison initially viewed it as a storage device for telephone data but later recognized its broader implications. It reflected the shift from a mechanical to an electrical era, where human vocalisation and rhythmic patterns in music saw a transformation.

However, while the phonograph became a central cultural tool, it was initially mishandled as a mere mechanical device without electric functionality. The human voice and rhythm found expression through phonographs, which also displayed the evolving nature of language and interpersonal communication.

Edison's insight regarding electrical phenomena reiterated his belief in the interconnectedness of problems and solutions. Despite early skepticism regarding the phonograph’s entertainment potential, it eventually became intertwined with business and media. The transition from mechanical forms of recording to electric mediums marked significant cultural evolution.

The phonograph's early sounds mirrored mechanical films, evoking a pervasive melancholy and paralleling the fine art of the late nineteenth century. This expression of mechanical to organic reflected the era’s nuanced cultural production. Jazz arrived as a reaction to highbrow music, serving as a bridge between elite and popular culture, while simultaneously reviving oral poetic forms.

The electric age brought forth new forms of media. The phonograph, once a fragmented product of industrial expansion, began to embody electric qualities once envisioned by Edison. It eventually became essential to the music industry and influenced post-war cultural consumption. The advent of tape recorders and high-fidelity systems transformed the phonograph, enabling deeper auditory experiences and reflecting a multifaceted engagement with sound, similar to cubism in visual art.

The integration of stereo sound represented an evolution toward depth in musical experiences, eliminating the old categorical distinctions between high and low culture. As the phonograph adapted to these transformations, it effectively bridged different historical musical genres and cultural norms, showing how technology reshapes cultural landscapes.

Ultimately, the chronological development of phonographic technology can be summarised as follows:

- The telegraph enables sound translation from writing.

- The telephone facilitates speech beyond physical barriers.

- The phonograph creates musical experiences unconfined by location.

- The photograph offers visual art free from geographical limitations.

- Electric light generates limitless spatial experiences.

- Movies, radio, and TV transform the classroom concept into a boundless experience.

In this progression, humanity’s role shifts towards information gathering, resembling the nomadic lifestyles of ancient food-gatherers.

29 Movies: the Reel World

Originally known as "The Bioscope," movie theaters in England were named for their ability to visually present the movement of life. Movies merge old mechanical technologies with electric advancements, bringing alive the medieval concept of change through entertainment. The developmental link between film and print is significant, as both mediums transport viewers into fantasy worlds. The power of cinema and literature stems from their ability to captivate audiences, often leading them to experience thoughts and realities beyond their own.

Movies, unlike language-heavy print forms, communicate nonverbally and are often challenging for nonliterate viewers, who may struggle to interpret visual sequences that literate audiences read as rational. The differences in visual comprehension between literate and nonliterate cultures reveal the complex relationship individuals have with media. For example, nonliterate audiences might see movement through a lens of magic and mythic interpretations rather than understanding continuity and perspective.

The evolution and impact of film are further explored through the works of iconic filmmakers and the adaptation of literature to screen. The relationship between film and society speaks to its role in shaping narratives of success and aspiration. As films portray broader themes of wealth and power, they engage audiences in ways that extend beyond mere entertainment.

As technology evolves, film’s role is redefined. The medium's potential is enhanced by emerging formats, leading to environmental shifts in how stories are told. The film industry inevitably adapts to contend with the challenges presented by television and shifting cultural expectations. Films like “Marty” highlight the different storytelling approaches that resonate in changing times, emphasising realism over glamour.

The narrative of cinema reflects societal values and aspirations, often framing personal stories against the backdrop of cultural and technological shifts. This interconnection underscores film’s ability to foster dreams, traditionally serving as a vehicle for self-fulfillment for varied audiences. As audiences continue to interact with film and media, the implications of these changes reflect broader transformations in individual and collective experiences.

30 Radio: the Tribal Drum

In a speech in 1936, Hitler described his commitment as that of a “somnambulist,” reflecting how both he and his critics were entranced by radio. This medium engages listeners deeply, often more so than reading, by creating a personal auditory experience that enhances social involvement. Radio fosters private worlds for individuals, allowing them to escape crowds.

Television’s emergence transitioned radio from primarily entertainment to a vital information system, emphasising news, weather, and traffic updates. This shift illustrated television’s cool nature, which tended to neutralise hot figures and controversial issues, ultimately resulting in the decline of figures like Senator McCarthy when he switched to TV.

Radio’s intimate interaction offers personal communication between speakers and listeners. This medium resonates with tribal roots, providing a sense of tribalism and shared experience, which can be powerful and explosive for communities less acquainted with literacy. Historical contexts show that radio could instinctively connect individuals, creating a collective resonance.

Literacy and print technology have structured societies with principles of continuity and uniformity, influencing education, law, and communal life. However, radio reverses this visual-centric approach, invoking tribal connections and emotional depths absent in literate societies.

31 Television: the Timid Giant

Television has strongly influenced children’s reading habits; they often hold books very close because TV has trained them to expect a more immersive sensory experience, so print can feel restrictive and frustrating. Studies using the Mackworth head camera found that children often focus on actors’ facial reactions more than on the action itself, even in violent scenes. This shows television as a “cool” medium that invites active audience involvement. Television, called “The Timid Giant,” tends to avoid hot issues and often self-censors. As a cool medium, it requires audience participation but frequently fails to engage local controversies well, which can make political discourse rigid.

English dialects have reappeared in schools, showing a shift toward local dialects that create social bonds instead of the previously dominant standard English. TV performers need a relaxed style to connect with audiences. The medium also makes political figures more acceptable when they appear casual on screen rather than overly polished.

Television’s greater psychological engagement affects learning, with students wanting deeper involvement rather than fragmented information. This encourages educational reform toward more interactive learning. TV reshapes tastes in clothing, art, food, and cars, favouring tactile, varied experiences over purely visual ones.

Television changes ideas about fame and celebrity: audiences prefer fictional roles over the actors themselves, unlike earlier times when attention centered on stars’ private lives. TV creates a two-dimensional experience that encourages strong participation and emotional connection, making it more immersive than visual or print media. Television affects presidential debates because its favoured traits can shape election results. Candidates with less fixed images often appeal more to viewers.

Television’s mosaic form increases audience participation and changes social expectations for involvement, creating deeper psychological engagement that challenges traditional linear media.

32 Weapons: War of the Icons

In June 1963, Valentina Tereshkova’s flight into space challenged the male-dominated field of astronautics, especially the American astronauts, and suggested a disconnect in East–West perceptions of space travel. The event symbolised the ongoing “war of the icons,” where technological advances and imagery overshadowed traditional military warfare. This shift reflects a Cold War characterised more by the manipulation of information and images than by direct conflict.

Historically, wars have evolved with technology. The Cold War represents a transition from industrial hardware to electric forms of persuasion. Madison Avenue recognised these changes, adapting its strategies from promoting products to creating collective corporate images. Political dynamics also became internationalised, with leaders campaigning across national borders, showing the breadth of modern information conflict.

The narrative highlights John Donne’s reflection on military advancements and the interconnectivity of technological progress, emphasising the relational impact between advances in weaponry and social change. A sense of interconnectedness stems from both military technology and the transition from a mechanical to an electric age, with weapons evolving to facilitate information processing rather than traditional combat.

The city symbolises collective defense and societal evolution, transitioning from physical fortifications to the complexities of information networks. Old industrial models struggle to adapt, as they clash with the realities of rapid information technology.

Ultimately, modern warfare, shaped by both mechanical and electric technologies, underlines a shift toward a unified human experience, urging a reconsideration of the political landscape in terms of global fraternity. Dewart’s insights reflect the obsolescence of fragmented power dynamics, envisioning a future where warfare represents existential conflicts rather than tactical supremacy.

33 Automation: Learning a Living

Automation not only eliminates specific jobs but also renders subject-based learning obsolete. With electricity as a transformative force, the way industries manage their resources changes dramatically. Instead of goods sitting in storage, contemporary inventories consist of materials undergoing continuous transformation across various locations. 

In education, the traditional curriculum’s separation into subjects becomes outdated. Understanding the interconnectedness of knowledge is vital for citizenship in a cybernated world. As insights into electricity progress, our understanding of energy systems evolves. Rather than being seen as contained elements, electricity is viewed as a condition influenced by various factors, fostering a unified field of experience akin to our central nervous system. 

This organic unity brings about a radical shift away from the mechanical separations of the past, emphasising instead the interconnected operations of both industry and entertainment. Automation signifies not just a continuation of mechanical principles, but an integration of instantaneous electric processes. The synchronisation of various operations replaces the sequential nature of mechanised labour leading to a new interconnectedness in both production and entertainment.

Themes

The medium is the message

McLuhan says:

"The medium is the message. This is merely to say that the personal and social consequences of any medium – that is, of any extension of ourselves – results from the new scale that is introduced into our affairs by each extension of ourselves, or by any new technology."

McLuhan refers to media as “extensions of ourselves.” The subtitle of the book is Extensions of Man. To McLuhan, media is anything that extends our capabilities as humans. As he says, “Any extension, whether of skin, hand, or foot, affects the psychic and social complex.” In other words, any media extends our capabilities. In the process, it changes how we think, and how we interact with one another.

Every medium alters what McLuhan calls “sense ratios.” We read a book with our eyes and our mind. We watch television with our eyes and our ears. The content of the medium comes to us through specific senses (sight, sound, touch, thought, etc.). As those senses are engaged, it affects how we use our other senses.

A subtle part of McLuhan’s basic description is that “personal and social consequences of any medium…[result]” from the altering of sense ratios. In other words, the characteristics of the medium cause personal and social consequences. What’s subtly implied here is that the content we’re so often concerned about – violence in video games, for example – is really caused by the medium itself.

Any medium is Darwinian in nature. Only organisms suited for their environment survive. Only messages suited for the environment created by their medium survive. The medium is the message.

Media have social consequences

So media extends our capabilities, alters our sense ratios, and shapes the messages within the media themselves. This has social consequences:

Road rage: It is easier to yell at someone in another car while you’re speeding away in your car than it is to say the same thing in an aisle in the grocery store. You get road rage.

Porn addiction: It is easier to look up porn on the internet to satisfy any sexual fantasy you might have than it is to deal with actual human relationships that normally surround sex. You get porn addiction.

Fake news: It is easier to share on Facebook an article you agree with, but that isn’t true, than it is to stop and study the article to consider whether it is true. Additionally, the attention that message gets makes Facebook money. So as more people share the article, it further fuels the message. You get fake news

Every new medium has brought about new and strange behaviors people criticise. Those behaviours are often a re-invention of existing behaviours. But that’s the point McLuhan is making, the characteristics of a medium change the message. That in turn heightens and dampens various aspects of our behaviour. To be unaware of how media changes us is a threat to civilisation.

We’re shifting from mechanical technology to electric technology

Mechanical technology alters our “sense ratios” in different ways from electric technology. The same way cogs on a gear have to be cut and sized to fit together, mechanical technology forces us to compartmentalise things in a way that allows mechanical technology to work.

A very basic mechanical technology is the alphabet. We’ve broken language into twenty-six characters we can arrange to make words that represent our thoughts. Before written language, we had to physically be in front of someone to communicate with them through spoken word. The language we speak itself is mechanical. It’s a mechanisation of our thoughts.

Until relatively recently, if we wanted to transport information – something as simple as “Let’s have dinner tonight” – we had to do so physically. McLuhan says the Roman Empire was able to govern because they distributed documents written on papyrus. They developed roads – a mechanical technology – primarily so they could physically move information throughout the empire. This enabled them to rule a massive area of land. Thanks to mechanical technology, Rome built a centralised government.

When Rome lost control of Egypt, they no longer had access to papyrus, so they could no longer distribute information. Europe decentralised it and fragmented into feudalism. It wasn’t until Europe adopted paper-making methods from China that information could flow freely again and Europe could condense into larger states.

An example of an electric technology is the telegraph. Before the telegraph was developed in the 1800s, you had to physically – or mechanically – move information from one place to another. With the telegraph, suddenly information that used to take weeks to reach its destination now took minutes.

This information flow has accelerated, and now we have the internet. Humans previously lived in a mechanical world: they could only be friends with kids who lived in their neighborhood, regardless of whether they had the same interests. Suddenly, they lived in an electric world: they could now be friends with anyone, anywhere.

But with this lifestyle that’s made possible by electric technology, I run into conflicts with the remnants of mechanical technology. The very concept of a country where I spend a different currency and where I need permission to stay is a result of mechanical technology. Centralised governments like the Romans built are mechanical. They organise people and land through physical means.

Media is an extension of our capabilities. The wheel – a mechanical technology – is an extension of the foot. Instead of walking wherever you like, the wheel lets you go faster, but you need roads on which to travel. 

However, McLuhan says electric technology is an extension of our nervous system. In the book, McLuhan essentially predicts Google Maps: he says existing technologies – including cities – will become information systems. When we have instant access to information all throughout the world, we “feel” that information just as we might feel a fluffy kitten or a hot stove.

Electric technology is retribalising humans

As we use electric technology to overcome physical stress – such as carrying a letter over oceans and mountain ranges – that creates psychic stress. Thanks to electric technology, communication sped up so that we could communicate across the world. That created physical stress of doing commerce from far away. So many of us moved, creating psychic stress of being away from friends and family. Another form of psychic stress caused by electric technology comes in the form of our simultaneous awareness of everything happening in the world at all times.

McLuhan describes a UNESCO experiment where they installed running water in a village in India. The villagers soon after asked for the pipes to be removed. They said the social life of the village had eroded. Thanks to running water, people were staying in their homes. They were no longer gathering at the communal well, so they were no longer chatting and maintaining relationships.

Before running water, the village was more tribal. The running water detribalised the village. It compartmentalised a very important function in their lives – that of getting water. It did that through the mechanical technology of pipes. It was more convenient, but by altering the “sense ratios” involved in getting water, it extracted that act from the social ritual that once surrounded it.

In a purely physical world, people tend to organise into small tribes or villages. Instead of being compartmentalised and specialised, there are deep interconnections in relationships and functions. Instead of just selling shoes, the cobbler makes them, too. The smaller the group of people, the more every death and birth and prayer is experienced together – shared by everyone in the tribe.

As electric technology has more influence, we’re increasingly retribalised. As McLuhan describes it, mechanical technology explodes, while electric technology implodes. The extension of our nervous system created by electric technology has made us more aware of how our local actions have effects on a global scale. Understanding Media, by the way, is where Marshall McLuhan coined the term, “global village.”

When you realize we are shifting from detribalised to retribalised as electric technology takes place of mechanical technology, the world starts to make sense.

Some examples of this change from mechanical to electric:

We’re shifting from industrialised food to organic food. Mechanical technology helped us increase crop yields and build reliable distribution of food. Electric technology is making us aware of where our food comes from, and the impact our food choices have on a global scale. We’re seeing a re-wilding of diets, as we introduce more biodiversity beyond the staples of corn, wheat, orange juice, and pork bellies. As people interpret this flood of information, different diets are springing up – like different “tribes” – such as keto, paleo, carnivore, pescatarian, vegetarian, vegan, and on and on.

Drugs are being legalised. The state control over what people put in their bodies is mechanical, as was the scare tactics and misinformation that helped reinforce that control. As more people are learning the truth about mostly harmless drugs such as marijuana, these drugs are becoming decriminalised and legalised.

Time is being reconsidered. Our linear conception of time is a relic of a mechanical world. Time has allowed us to increase output by breaking processes into steps, and allowing the coordination of those steps amongst people and organizations. But as electric technology is allowing free information flow, and automation is making “work” obsolete, creativity is becoming more important.

The state of the world becomes clearer if we ask: Is it a conflict between mechnical and electric technology? You can see it in the questioning of whether a police force is the right way to restore order in society, in the gendered bathroom debate, in Russia’s media manipulation in American society and in the rise of Bitcoin.

McLuhan sees our lack of awareness of how media affects us as a threat to civilization:

The threat of Stalin or Hitler was external. The electric technology is within the gates and we are numb, deaf, blind and mute about its encounter with the Gutenberg technology, on and through which the American way of life was formed. It is, however, no time to suggest strategies when the threat has not even been acknowledged to exist. McLuhan compares the effects of electric technology to Hitler. He warns that it’s foolish to think of technology as “neither good nor bad.” The solution, he says is to start by being aware that the very nature of media alters our behaviour in the first place.

He reminds us that we misunderstand the Greek Myth of Narcissus. Narcissus saw his reflection in the river, and stared at it longingly until he withered away. We think of narcissism as an obsession with oneself. McLuhan reminds us there is something missing from our modern understanding of the myth of Narcissus: That Narcissus didn’t know he was looking at himself. Narcissus’s name comes from the Greek word for “narcotic.” As media takes over our senses, it numbs us – like a narcotic – from the true effect it’s having. We need to become aware of how media affects us.

"It is not an exaggeration to say that the future of modern society and the stability of its inner life depend in large part on the maintenance of an equilibrium between the strength of the techniques of communication and the capacity of the individual’s own reaction."

The Extensions of Man

The concept of media as extensions of human faculties is a profound exploration of how technology interacts with and enhances our natural abilities. When we think about the wheel, for example, it is not merely a mechanical invention; it fundamentally transforms our capacity for movement. By extending our legs, the wheel allows us to travel greater distances with less effort, thereby altering our relationship with space and time. This transformation is not just physical; it also has social implications, as it enables trade, communication, and cultural exchange across larger areas.

Similarly, the telephone serves as an extension of our voice, allowing us to communicate over vast distances instantaneously. This technological advancement reshapes interpersonal relationships and societal structures by enabling real-time conversations regardless of location. The implications of such extensions are profound because they change the way we interact with one another, how we perceive distance, and how we construct our social networks.

By viewing media through the lens of extensions, we begin to see that every form of technology we create serves to amplify certain human capabilities while simultaneously altering others. For instance, the advent of social media platforms extends our ability to connect and share information, but it also raises questions about the authenticity of those connections and the nature of our identities in a digital landscape.

This perspective encourages a critical examination of how these extensions influence our daily lives and the broader societal context. It prompts us to consider not just the utility of a technology, but its deeper implications for human experience. The ways in which we communicate, learn, and even think are all mediated by these extensions, leading to a reevaluation of what it means to be human in a world increasingly shaped by technological innovations.

In a media-saturated environment, understanding these extensions becomes crucial. It allows us to navigate the complexities of our interactions and identities in a world where the lines between the physical and the digital are increasingly blurred. By recognising that media are not just tools but integral components of our existence, we can better appreciate their role in shaping our perceptions, relationships, and ultimately, our humanity. This understanding challenges us to critically engage with the media we consume and create, fostering a more conscious approach to technology in our lives.

The Role of the Artist

The artist is portrayed as a pivotal element in the broader discourse surrounding media and its impact on society. Artists are not merely creators of aesthetic works, they are seen as vital interpreters and critics of the cultural landscape shaped by various forms of media. In this context, the artist's function transcends traditional boundaries, positioning them as essential figures who can dissect and elucidate the complex relationship between technology and human experience.

Artists possess a unique ability to perceive and articulate the subtle shifts in perception and behaviour that arise from the introduction of new media. They serve as cultural commentators who can highlight the nuances of how media influences thought, communication, and social interaction. By engaging with and reflecting upon the effects of media, artists can challenge dominant narratives and question the status quo, providing alternative perspectives that encourage critical thinking.

Through their work, artists can reveal the underlying structures and assumptions that govern societal interactions with technology. They often explore and expose the ways in which media can shape identities, influence power dynamics, and alter the fabric of community life. This critical engagement is crucial in a world increasingly dominated by technological advancements, as it invites audiences to reflect on their own relationships with media and the implications of those relationships.

Moreover, artists can act as catalysts for societal change by provoking dialogue and inspiring action. Their creative expressions can resonate deeply with individuals, prompting them to reconsider their own experiences and the broader societal implications of media consumption. In this sense, artists are not only observers but also participants in the ongoing conversation about the role of technology in shaping human existence.

Ultimately, the importance of the artist lies in their capacity to foster awareness and understanding of media's pervasive influence. By illuminating the often-overlooked effects of media on culture and society, artists encourage a more profound engagement with the technological landscape, empowering individuals to navigate the complexities of an ever-evolving media environment. This perspective underscores the necessity of integrating artistic insight into discussions about media, as it enriches our comprehension of the intricate interplay between technology, culture, and human experience.

The Rear-View Mirror

The concept of the "rear-view mirror" serves as a critical metaphor for understanding how individuals and societies often perceive and interpret new technologies. This metaphor highlights a common cognitive bias where people tend to evaluate and judge the innovations of the present based on their prior experiences and the established norms of the past. In doing so, they inadvertently limit their ability to fully grasp the potential and implications of emerging media.

When individuals rely on the rear-view mirror approach, they tend to see new technologies merely as extensions or enhancements of existing ones. For instance, the advent of the internet might be viewed simply as a faster way to send letters or print newspapers, rather than as a revolutionary platform that transforms communication, social interaction, and access to information on a global scale. This limited perspective can lead to a failure to appreciate the unique characteristics and capabilities that new media bring to the table.

Moreover, this tendency to anchor oneself in familiar paradigms can result in resistance to change. People may cling to traditional forms of communication and interaction, fearing that new technologies will disrupt established social orders or cultural norms. This fear can stifle innovation and hinder the adoption of beneficial advancements that could enhance human experience and societal progress.

By urging individuals to shift their focus from the rear-view mirror to a forward-looking perspective, the text advocates for an active engagement with new media. This proactive approach encourages individuals to explore the transformative effects of technology without being bogged down by outdated frameworks. It emphasises the importance of understanding how new tools can reshape perceptions, behaviors, and social structures in ways that were previously unimaginable.

In essence, the call to look forward rather than backward is a plea for open-mindedness and adaptability in the face of rapid technological change. Embracing this perspective allows for a more nuanced understanding of the complex interplay between media, culture, and society, ultimately fostering a greater appreciation for the potential of new technologies to enrich human life and drive innovation.

The Effects of Media on Perception

The concept of how media influences perception delves deeply into the intricate relationship between the medium through which information is conveyed and the way we interpret and understand that information. It posits that each type of media — be it print, television, radio, or digital platforms — has unique characteristics that not only deliver content but also fundamentally shape our sensory experiences and cognitive processes.

When we consider print media, for instance, it traditionally engages a slower, more reflective mode of consumption. Readers have the opportunity to pause, reflect, and digest information at their own pace. This medium fosters a linear and analytical thought process, encouraging critical engagement with the text. The permanence and physicality of printed words provide a sense of stability and authority, creating a different relationship with the information presented. Readers can feel more anchored, trusting, and reflective with printed text because it seems fixed, tangible, and less transient than digital text.

Criticism

Media: Extension of Man

McLuhan provides an extremely vague description of what he means by media, for it encompasses everything from writing, clothing, and automobiles, to television, radio, and computers. Had he coined a new keyword instead of redefining "media," it wouldn't have been difficult to understand that he was merely referring to any matter or force that amplified the five physical senses by any means or modes. And yet the world today, almost forty years after he authored Understanding Media, continues to exemplify his statement recurrently. 

One notable stance he takes in his analysis of media is that he does not exaggerate or even emphasise human increasing dependence on the tools of technology as a negative move or a threatening issue. He does not see humanity becoming a slave because of our reliance on technology. He sees us becoming a slave because he subconsciously chooses to ignore and disregard the fact that understanding the new web of media is incumbent to his survival and prosperity. Though not a lucid viewpoint, this indeed is the difference between McLuhan's mind and those of the others who preceded him in the study of media, technology, and even human psychology. He saw the world like no one had ever seen it before - in depth, devoid of any previous assumptions, keen to form new ideas, and willing to shed old theories.

Hot or Cold

Radio is hot, television is cool, lectures are hot, and seminars are cool. McLuhan's classification of media takes into account only two factors: participation and information. Any medium low in participation and high in information content is hot. A medium engaging higher participation but providing less quantity of information is cool. It is a surprise that someone actually noticed these imperceptible yet inherent distinctions between the various forms of media, because now that McLuhan explained the factors that make something hot or cool, it has become almost child's play to predict if a given method of using a media will work effectively or not. 

McLuhan cites the example of two American Presidents, Kennedy and Nixon, both of whom projected impressionable persona on the television. However, whereas Kennedy remained calm, cool, and low-definition, Nixon tended to be aggressive, hot, or in other words, high-definition. This cost Nixon the presidency. Yet later when he composed himself, presumably under the advice of someone who recognized the lack of believability in his hot and intensified behaviour, he won the vote and was elected President. 

Though McLuhan clearly distinguishes what makes a medium hot or cool, recognising the same is quite counterintuitive. In the present day, when more people call up the local radio stations than the national television, it seems that radio is cooler since it involves more participation. Also with the advent of modern information gathering and broadcasting channels, television, primarily through news and live-talk shows, gives a plethora of information about almost everything, and thus might be construed as hot if McLuhan's definition is taken literally. While in some cases it might be true that radio is cooler or television is hotter figuratively speaking, in a broader sense the idea that radio is essentially hot and television primarily cool still holds true, because even today, television is more of a full body-mind involvement experience than radio. Television begs the devotion of the viewer's entire nervous system, where as radio only engages the aural system. Despite the explosion of high definition televisions in today's electronic market, the medium itself is still low definition. 

Yet again McLuhan reinterpreted a common catch phrase and gave it a hitherto unknown dimension, for the term definition now measured participation and its the lack. That radio is a high-definition medium is a well known fact. Yet, the use of the word definition to describe something as far-fetched as participation, goes on to show why McLuhan has been fondly called the metaphysician of media, shrouded in mysticism.

Three technological innovations

It would be difficult to disagree with McLuhan on his choice of the three technological innovations that have affected mankind the most: Phonetic alphabet, movable type, and the telegraph. Citing these three as the major breakthroughs that transmogrified the tribal man into the "Gutenberg man," McLuhan boldly claims that each and every mechanical invention attributes its success to the printing press. 

Gutenberg's invention indeed revolutionised the world, for it brought the luxury of knowledge to the common man. No longer was education a frill for the posh, but instead available to anyone who sought to absorb it. And it was this easy access to resources and textual materials, that the plebeian also became the thinker, the inventor, and the revolutionary. Interestingly, he notices that there exists one major inequality between the old print, text, and type media and the new electronic media, that is, while all previous media tended to detribalise man and Westernise him into a linear mode of existence, electronic media is drawing him back to his ancestral roots of tribal harmony. McLuhan makes yet another bold proposition and as usual describes the processes that lead him up to the claim.

Tribal and Fragmented Man

Though it seems quite inapplicable to the context of modern day media, McLuhan talks in length about the tribal man and his peaceful existence in harmony with his kinship and environment. He makes this apparent digression into the glorification of the ways of life of the simplest human societies just to prove wrong almost every preconception about the tribal man and apply the newly found exposition to the man of today. 

There is long-held belief in the Western mind that the tribal man is uncivilised, simple, and primal with little or no cultural richness. This point of view, coupled with the misconception that the Westernized linear mode of traditional thought and discourse is far superior to that of the tribal man, has prevented the modern man from opening himself up to exploration of the new media and realisation of its capability. 

The tribal man "lived in a world where all the senses were balanced and simultaneous, a closed world of depth and resonance," whereas the "literate or visual man creates an environment that is strongly fragmented, individualistic, explicit, logical, specialised and detached." McLuhan seems to have the uncanny ability to look at the world from a peculiar standpoint, like that of a first grade student, eager to learn his first nursery rhyme. 

He has presented a very startling observation of the literate man, as if intentionally begging vehement opposition. Yet if all prejudices are set aside for a moment, it slowly becomes evident why the modern man is "fragmented" according to McLuhan. His interpretation of fragmented illustrates modern man's lack of connectivity with the others in his society. Moreover, McLuhan points Gutenberg man's increasing reliance on his sight and gradual deviation from aural senses. Then McLuhan brings yet another new concept, that of "retribalization" of the Gutenberg man by the electronic media and its silent force capable of reuniting the world of mankind, giving birth to the "Integral Man."

Integral Man

It is nothing short of a wonder that McLuhan correctly foresaw and predicted life in the digital world and the days of Information Superhighway, thirty years before Internet opened its gates to the commercial world. He saw the future of the world as being born out of the womb of mass computerisation. 

Most importantly, he saw the "Integral man," more frequently known today as the "connected" man. His idea of integral was no less than revolutionary for the time, yet evidences to support the same are already blooming all across the world. Just like the tribal man, the integral man would be in a state of "multitudinous tribal existence," and his world would be filled by a "synaesthetic discontinuous integral consciousness," a connection so strong that it will bind everything to everything else, forming a "single universal membrane." 

At this point, McLuhan's ideas leave the boundaries of possibility and potentiality and escape into the future where everything is possible. The integral man will be part of a global telepathic cluster where computers will literally read the mind and broadcast thoughts appropriately. This according to him is simply the next step in communication and media. What began with phonetic alphabets, transformed into printing press and telegraph, will finally end in mind-reading electronic devices which will take humanity back to their original tribal existence, where emotions and expressions were more valued than analysis and consciousness. It will be the world of artists, not scientists. This is quite a daring prophecy, McLuhan's specialty, as well as one of his proven strengths.
