McLuhan

Works

Two books of argument, one of design, and a posthumous attempt at a method.

• The Gutenberg Galaxy (1962) sets out the claim that phonetic literacy and print produced a linear, sequential, visually biased consciousness.
• Understanding Media (1964) contains the medium as message, the extensions and their numbing, and the hot and cool distinction.
• The Medium is the Massage (1967) is a designed book that made the ideas famous and made them harder to assess.
• Laws of Media (1988), completed posthumously, offers the tetrad — every medium enhances, obsolesces, retrieves and reverses — as a testable heuristic rather than a probe.

Central ideas

Four, and the second is the one worth taking as an analytic tool.

• The medium is the message: the content of any medium is another medium, and the consequential change is in the environment a medium creates rather than in what it transmits. The electric light is the example — a medium with no content at all that nonetheless reorganises when and where things happen.
• Extension and numbing: every technology extends a faculty and anaesthetises what it extends. The pair is not a lament; it is a claim that gain and loss are the same event, which is why a new capability is hard to evaluate from inside it.
• Figure and ground: attend to the environment a medium creates rather than to what stands out in it, since the environment is what nobody notices.
• The global village: electric media restore a simultaneous, acoustic condition. He described it as a place of maximal friction and disagreement, not of harmony, and the cheerful reading is a misreading.

Distinctive vocabulary

Three terms whose popular senses reverse or flatten them.

• The medium is the message: a claim that a medium's environmental effects matter more than its contents. Not a claim that style matters more than substance.
• Global village: a condition of simultaneity and abrasive proximity. Not a hopeful image of connection, whatever the phrase now conveys.
• Hot and cool: a distinction by definition and participation. He applied it inconsistently and it has not survived as a working taxonomy.

Debates and disagreements

The strongest objection is that the formalism removes politics.

• The cultural-studies critique holds that treating a medium formally abstracts it from the social and economic relations that produced it and determined its uses — so a medium appears to act on society when it was made by one. That objection also removes the determinism's political consequences, which is why it has force beyond method.
• The literacy thesis shares the divide problem: the claim that literacy restructures consciousness is contested, and cross-cultural work on literacy learned outside schooling is the standard counter-evidence.
• Whether the aphoristic method is a method. He called them probes, which makes them generative and unfalsifiable at once.

Intellectual relationships

One acknowledged predecessor, one student, and two later opponents.

• Innis's work on the bias of communication is the acknowledged source — McLuhan called his own book a footnote to it — and Innis kept the economics and the politics that McLuhan dropped.
• Ong, in this same lens lineage, was his student and made the literacy argument more carefully and more empirically, though it remains contested.
• Kittler, in this lineage, rejects the humanism explicitly: media as extensions of man is precisely what a materialist media theory was written against.
• Manovich, in this lineage, replaces the aphorism with measurement, which is a disagreement about evidence rather than about subject.
• His Catholic and Thomist formation shaped the work and went largely unmentioned in its popular reception.

How it changes this reading

McLuhan is named in the lineage of the Media-theoretic lens, completing it.

• He supplies the lens its founding instruction: look at the form and at the environment it creates rather than at what it carries, because the environment is the part nobody is attending to.
• Extension and numbing is the more usable borrowing here, and it is the honest one. A capability added is a capability numbed, so an arrangement that makes something easier has also made something else harder to notice — which is a claim about any system that renders a life more legible, this one included.
• The tonal correction belongs with the placement. The global village is his term for abrasive simultaneity, not for connection, and citing him as an optimist about media misrepresents him.
• It is not evidence about anyone's media use or about how any record was made.

Useful comparisons

The lens is complete with him, and its four members disagree about evidence itself.

• Marshall McLuhan: media as extensions of human faculties, argued by probe and aphorism.
• Friedrich Kittler: media as material conditions, argued archivally and against humanism.
• Lev Manovich: software and data, argued empirically and taxonomically.
• Walter Ong: orality and literacy, argued historically and philologically.

Where the ideas meet

None of the four treats a medium as a neutral pipe.

• None treats a technology of inscription as indifferent to what passes through it.
• All four hold that a change of medium changes what is possible rather than only what is convenient.
• Each treats the material conditions of recording as belonging to the analysis.

Where they part

He is the one the other three define themselves against.

• Kittler's programme rejects the humanism directly: media that extend a person presuppose the person whose priority Kittler denies.
• Manovich's method is measurement where McLuhan's is the probe, which is a disagreement about what would count as evidence rather than about what to study.
• Ong made the literacy claim carefully enough to be tested, and it was tested and contested; McLuhan's version was never in a form that could be.
• Innis, outside the lineage, is the predecessor who kept the political economy McLuhan set aside, which is why the same tradition produces both a formalism and its critique.

Limits

What this reference can carry here is narrow, and one limit is his own framing.

• Probes are not findings. He said so, and citing an aphorism as an established result misuses it in the way he specifically warned against.
• The literacy and consciousness thesis is contested and cannot ground a claim here.

Criticisms

The objections are strong and one of them is political.

• Formalism abstracts a medium from the social and economic relations that made it, which makes technologies look like agents and removes the question of who decided.
• Hot and cool is unworkable, and his own examples do not cohere under it.
• The literacy thesis shares the divide problem with the rest of that tradition and has counter-evidence against it.
• The aphoristic method resists testing by design, so the work generates readings rather than results.
• The popular reception inverted his pessimism, and a great deal of what circulates under his name is the opposite of what he argued.

Common misreadings

Four uses this placement does not license.

• Reading the global village as a hopeful image of connection, which reverses the abrasion he described.
• Using the medium is the message to mean that form matters more than substance in an ordinary sense.
• Citing hot and cool as a working taxonomy.
• Treating the probes as findings, which he explicitly declined to claim for them.

What remains outside this idea

• It cannot establish anything about any person's media use or attention.
• It cannot convert an aphorism into a finding about a life.
