The word as utterance rather than as sign — McLuhan's subject in one of the less-quoted tetrads from Laws of Media, and the term Bob Dobbs uses to explain why a president who cannot finish a sentence is more involving than one who can. Dialogue 80 reads the Tetrad out in full and then hands it to Cameron, who supplies both the Latin behind it and the Toronto Jesuit who wrote a book of the same name.
Across the dialogues
Stops being a McLuhan Tetrad quoted in passing and becomes the hinge of the Trump chapter — with Cameron supplying the Latin and the Jesuit rival that give the term a scholarly weight the pamphlet had not claimed for it
The broken sentence is reclassified as a medium — incompleteness is what leaves room for the listener, so the deficit becomes the mechanism.
"Don Trump does not have to speak in complete sentences. He creates involvement by engaging the verbum."Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 1:57:23
Bob puts two presidents inside a McLuhan Tetrad rather than inside politics, which is the move the whole chapter depends on.
"So then the Tetrad on verbum, which is utterance. So Trump and Biden are utterers. They're just primitive utterers, grunt people."Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:03:15
The first two arms read as a hardening — the utterance sets into an object, and in doing so puts the senses out of work.
"It intensifies and crystallizes, there's your crystal percept, as word. So word is also a thing. Obsolescence is merely sensory via perceptual interplay."Marshall McLuhan, read by Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:03:32
The correction changes the Tetrad's meaning — res is not an object but what is real, so the first arm is about the word becoming reality, not becoming furniture.
"For thing in the intensifies line, thing in Latin is res. And so it's not the word as thing as something sort of lying around. It's the thing as it's the word as reality."Cameron McEwen, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:03:56
The retrieval arm names a transfer of authority, and the flip between word and thing is what makes the pair tactile rather than referential.
"transfers of power from things to word as vortex. So there's a tactile interplay between word and thing, right? They flip back and forth."Marshall McLuhan, read by Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:04:57
Bob reaches for the rhetorical figure that already describes the structure — the pair is not two things related but one thing said twice.
"Hendiadys, one by means of two."Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:05:15
The reversal is the loss the Tetrad is built to expose — pushed far enough, utterance becomes concept, which is meaning with the encounter stripped out.
"Reverses into the conceptual. Replay of meaning minus the experience."Marshall McLuhan, read by Bob Dobbs, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:05:19
Cameron places the term in a rival Toronto lineage, and Bob's answer — that Lonergan was McLuhan's competition and he never read him — marks the boundary of the pamphlet's scholarship.
"What's the name of the Jesuit in Toronto? Lonergan. his first big book was Verbum."Cameron McEwen, The Resonant Interval, Dialogue 80 (14 Dec 2023), 2:07:45
Connections
Bob reads the four laws of verbum out of McLuhan's June 1977 Etc magazine piece.
Trump's broken sentences are read as engagement with the verbum rather than a failure of speech.
