The Gutenberg Galaxy

McLuhan declares his book to be "complementary to The Singer of Tales by Albert B. Lord."[8] The latter work follows on from the Homeric studies of Milman Parry who turned to "the study of the Yugoslave epics"[8] to prove that the poems of Homer were oral compositions.

The oral tradition is not dead. In schools or at home or in the street, where children are taught to learn by heart, to memorize, nursery rhymes or poems or songs, then they can be said to participate in the oral tradition. The same is often true of the children belonging to religious groups who are taught to learn to say their prayers. In other words, childhood is one of the ages of man (in Shakespeare's sense) and is essentially an oral tribal culture. The transition from this oral culture takes place when the child is taught to read and write. Then the child enters the world of the manuscript culture.

McLuhan identifies James Joyce's Finnegans Wake as a key that unlocks something of the nature of the oral culture.[12]"

Of particular importance to the Oral Culture is the Art of memory.

In commenting on the then Soviet Union,[13] McLuhan puts "the advertising and PR community" on a par with them in so far that both "are concerned about access to the media and about results."[14] More remarkably he asserts that "Soviet concern with media results is natural to any oral society where interdependence is the result of instant interplay of cause and effect in the total structure. Such is the character of a village, or since electric media, such is also the character of global village."[14]

The culture of the manuscript (literally hand-writing) is often referred to by McLuhan as scribal culture.

Medieval illumination, gloss, and sculpture alike were aspects of the art of memory, central to scribal culture.[15]

Associated with this epoch is the Art of memory (in Latin Ars Memoriae).

Finnegans Wake: Joyce's Finnegans Wake (like Shakespeare's King Lear) is one of the texts which McLuhan frequently uses throughout the book to weave together the various strands of his argument.

Throughout Finnegans Wake Joyce specifies the Tower of Babel as the tower of Sleep, that is, the tower of the witless assumption, or what Bacon calls the reign of the Idols.[16]

His episodic history takes the reader from pre-alphabetic tribal humankind to the electronic age. According to McLuhan, the invention of movable type greatly accelerated, intensified, and ultimately enabled cultural and cognitive changes that had already been taking place since the invention and implementation of the alphabet, by which McLuhan means phonemic orthography. (McLuhan is careful to distinguish the phonetic alphabet from logographic/logogramic writing systems, like hieroglyphics or ideograms.)

Print culture, ushered in by the Gutenberg press in the middle of the fifteenth century, brought about the cultural predominance of the visual over the aural/oral. Quoting with approval an observation on the nature of the printed word from Prints and Visual Communication by William Ivins, McLuhan remarks:

In this passage [Ivins] not only notes the ingraining of lineal, sequential habits, but, even more important, points out the visual homogenizing of experience of print culture, and the relegation of auditory and other sensuous complexity to the background. [...] The technology and social effects of typography incline us to abstain from noting interplay and, as it were, "formal" causality, both in our inner and external lives. Print exists by virtue of the static separation of functions and fosters a mentality that gradually resists any but a separative and compartmentalizing or specialist outlook.[17]

The main concept of McLuhan's argument (later elaborated upon in The Medium is the Massage) is that new technologies (like alphabets, printing presses, and even speech itself) exert a gravitational effect on cognition, which in turn affects social organization: print technology changes our perceptual habits ("visual homogenizing of experience"), which in turn affects social interactions ("fosters a mentality that gradually resists all but a... specialist outlook"). According to McLuhan, the advent of print technology contributed to and made possible most of the salient trends in the Modern period in the Western world: individualism, democracy, Protestantism, capitalism and nationalism. For McLuhan, these trends all reverberate with print technology's principle of "segmentation of actions and functions and principle of visual quantification."[18]

In the early 1960s, McLuhan wrote that the visual, individualistic print culture would soon be brought to an end by what he called "electronic interdependence": when electronic media would replace visual culture with aural/oral culture. In this new age, humankind will move from individualism and fragmentation to a collective identity, with a "tribal base." McLuhan's coinage for this new social organization is the global village.[19]

The term is sometimes described as having negative connotations in The Gutenberg Galaxy, but McLuhan himself was interested in exploring effects, not making value judgments:

Instead of tending towards a vast Alexandrian library the world has become a computer, an electronic brain, exactly as an infantile piece of science fiction. And as our senses have gone outside us, Big Brother goes inside. So, unless aware of this dynamic, we shall at once move into a phase of panic terrors, exactly befitting a small world of tribal drums, total interdependence, and superimposed co-existence. [...] Terror is the normal state of any oral society, for in it everything affects everything all the time. [...] In our long striving to recover for the Western world a unity of sensibility and of thought and feeling we have no more been prepared to accept the tribal consequences of such unity than we were ready for the fragmentation of the human psyche by print culture.[20]

Key to McLuhan's argument is the idea that technology has no per se moral bent—it is a tool that profoundly shapes an individual's and, by extension, a society's self-conception and realization:

Is it not obvious that there are always enough moral problems without also taking a moral stand on technological grounds? [...] Print is the extreme phase of alphabet culture that detribalizes or decollectivizes man in the first instance. Print raises the visual features of alphabet to highest intensity of definition. Thus print carries the individuating power of the phonetic alphabet much further than manuscript culture could ever do. Print is the technology of individualism. If men decided to modify this visual technology by an electric technology, individualism would also be modified. To raise a moral complaint about this is like cussing a buzz-saw for lopping off fingers. "But", someone says, "we didn't know it would happen." Yet even witlessness is not a moral issue. It is a problem, but not a moral problem; and it would be nice to clear away some of the moral fogs that surround our technologies. It would be good for morality.[21]

The moral valence of technology's effects on cognition is, for McLuhan, a matter of perspective. For instance, McLuhan contrasts the considerable alarm and revulsion that the growing quantity of books aroused in the latter seventeenth century with the modern concern for the "end of the book." If there can be no universal moral sentence passed on technology, McLuhan believes that "there can only be disaster arising from unawareness of the causalities and effects inherent in our technologies."

Though the World Wide Web was invented thirty years after The Gutenberg Galaxy was published, McLuhan may have coined and certainly popularized the usage of the term "surfing" to refer to rapid, irregular and multidirectional movement through a heterogeneous body of documents or knowledge, e.g., statements like "Heidegger surf-boards along on the electronic wave as triumphantly as Descartes rode the mechanical wave." Paul Levinson's 1999 book Digital McLuhan explores the ways that McLuhan's work can be better understood through the lens of the digital revolution.[22] Later, Bill Stewart's 2007 "Living Internet" website describes how McLuhan's "insights made the concept of a global village, interconnected by an electronic nervous system, part of our popular culture well before it actually happened."[23]

McLuhan frequently quoted Walter Ong's Ramus, Method, and the Decay of Dialogue (1958), which evidently had prompted McLuhan to write The Gutenberg Galaxy. Ong wrote a highly favorable review of this new book in America.[24] However, Ong later tempered his praise, by describing McLuhan's The Gutenberg Galaxy as "a racy survey, indifferent to some scholarly detail, but uniquely valuable in suggesting the sweep and depth of the cultural and psychological changes entailed in the passage from illiteracy to print and beyond."[25]

McLuhan's The Gutenberg Galaxy won Canada's highest literary award, the Governor-General's Award for Non-Fiction, in 1962. The chairman of the selection committee was McLuhan's colleague at the University of Toronto and oftentime intellectual sparring partner, Northrop Frye.[26]
