person
also known as Don Theall, Theall

McLuhan's closest interlocutor in the early 1950s. Theall arrived from Yale in 1950, met McLuhan almost daily through 1953, brought him the cybernetics literature (Wiener), and — with McLuhan — ran the 1950–51 Finnegans Wake reading group that Cameron credits as decisive in McLuhan's turn to the Wake. The page follows that collaboration from its start to the mid-50s Tennyson study McLuhan co-wrote with him.

Across the dialogues

01

Arrives from Yale in 1950 and starts the Finnegans Wake reading group with McLuhan

Theall's arrival in 1950 launched the Finnegans Wake reading group that produced McLuhan's early breakthroughs.

"When Theall comes in 1950 and they start doing a Finnegans Wake reading group."
Bob Dobbsasserted

Theall left Lewis out of his doctoral thesis — Lewis' paintings were sealed in Ottawa — to McLuhan's lasting annoyance.

"Marshall was mad at him because he didn't include Wyndham Lewis in his PhD on communication theories of Pound, Eliot, Yeats and Joyce. Don said he couldn't do Lewis because his paintings were locked up at the National Archives in Ottawa, and he felt he couldn't do justice to Lewis without access to the painting."

03

Becomes McLuhan's daily interlocutor — brings him cybernetics and serves as the group's secretary

Theall brought McLuhan the cybernetics literature (Wiener) — turning him toward cybernetics and MIT.

"Don shows up in 1950 and gives McLuhan The Human Use of Human Beings, or Cybernetics — can't remember which. Don said that he turned McLuhan on to cybernetics and MIT."
Bob Dobbsasserted

Theall served as secretary on the McLuhan–Carpenter Ford grant application of 1952–53.

"As Carpenter gets involved with McLuhan, Don is the secretary for the two of them when they make their application to the Ford situation in '52–53 — the Ford grant."
Bob Dobbsasserted

By Theall's account, he and McLuhan were reading "the world of kook" and looking into alchemy in the early 1950s.

"Like Don said, they read this, the world of kook in the early '50s, and they're looking into alchemy."

Co-authors the Tennyson epyllion study — the collaboration McLuhan later left unattributed

McLuhan co-wrote the mid-50s Tennyson epyllion study with Theall — without crediting Havelock, whose epyllion work came first.

"He's writing with Theall in his book in the mid-50s on Tennyson. No mention of Havelock."
Bob Dobbsasserted

Two Theall readings surface — his Menippean/Varronian typology sorting Lewis, Joyce and McLuhan by temperament, and his image of McLuhan as "a canary in the mine" who acted out everyone's life in advance

Theall's summary reading of McLuhan — "a canary in the mine," going through in advance what everyone would go through — which Bob enlists for his own eschatological case that people now confront their emptiness faster, exactly the point Cameron refuses.

"Don Theall said that McLuhan acted out our lives."
Donald Theall, read by Bob Dobbsreported

The star student turned adversary — his too-wide thesis reread as a "clue" to McLuhan's early classes, and his life's work reframed by Cameron as a deliberate misunderstanding born of a personal grievance

Cameron's verdict on Theall's doctoral thesis — covering "Joyce and Eliot and Pound and… everybody but Lewis," it was "way too wide to be useful," since "all of those people require a lifetime of thought."

"I think everybody but Lewis, it's way too wide to be useful."
Cameron McEwenasserted

Bob's countervailing read — the thesis still "gave a clue of what Marshall said and what a smart student picked up in Marshall's classes in the early 50s," and Theall was "the brightest student," "a good mime" and "a good absorber" — yet he "dedicated his life to misunderstanding McLuhan, because he was pissed off at McLuhan in some way, personally."

"He dedicated his life to misunderstanding McLuhan, because he was pissed off at McLuhan in some way, personally…"
Bob Dobbsasserted

Recast as McLuhan's loyal double agent — the schizoid (not schizophrenic) diagnosis Bob turns into quadrophrenia, the hospital-written Rear View Mirror, the Grierson camaraderie, and a fidelity to McLuhan that outlasted his own grievance

Theall's diagnosis of McLuhan defended and extended — Bob insists Theall called McLuhan "schizoid," a slang word for the way he "seems to contradict himself," not the clinical "schizophrenia" Cameron half-remembered; it is this schizoid reading Bob says he "goes further" into as quadrophrenia.

"no problem saying schizoid. It's a slang term. It's not even the disease of schizophrenia."
Bob Dobbsasserted

The accidental origin of Theall's first McLuhan book — hospitalized around 1970 after the drinking-heavy camaraderie with John Grierson, Theall wrote The Medium Is the Rear View Mirror only because he was "laid up," having had no interest otherwise in "writing a book on McLuhan."

"and that's when he wrote The Medium Is the Rear View Mirror while he was in the hospital."
Bob Dobbsasserted

Supplies both a technical pair and a piece of Toronto mythology — his synesthesia/coenesthesia terms are borrowed for the Tech Body, and his Illuminati story is told and then doubted

Bob retails the lineage as a fantasy he nonetheless keeps — Cameron doubts Carpenter or McLuhan took it seriously, and the disagreement is really about whether the Toronto group knew what it had.

"And that's where Don Theall said the historical fantasy of the Illuminati, you know, was way back in Babylon, and then in Greece, then Rome, then... Venice maybe, and then England, then America, and then he said, then Toronto."
Donald Theall, quoted by Bob Dobbsreported
69

Credited with the distinction the session's central page turns on — Bob attributes the affect/effect split to him and dates it, so a term Bob had been using as his own is given a source inside the Toronto circle

The distinction Cameron cannot parse on Bob's page is given an author and a date — Theall's, not McLuhan's, which is why the word sits oddly in a McLuhan reading and why Bob has to capitalize it to keep it straight.

"Theall started talking about affects versus effects in the late 80s, and people weren't using affects. They were using effects when they were dealing with McLuhan, because that's what he said."
Bob Dobbsasserted

The debate's closing "thud" is read as an eleventh thunder past the canonical ten — thunder with the -ner condensed out, which is what lets the whole Berkeley passage count as a replay.

"Don Theall pointed out that thud is the 11th thunder."
Donald Theall, read by Bob Dobbsreported

Co-anesthesia is the digital successor to the sixties' synesthesia — where the global theater surrounded you, the digital surround seats you at its controls.

"Co-anesthesia, as Theall points out, is gradually putting you at the center of the driving mechanism."
Donald Theall, read by Bob Dobbsreported

Theall's verdict becomes Bob's own self-description — McLuhan did not stand outside his period diagnosing it but performed its symptoms slightly early, which is the drama Bob then enrols himself in.

"Theall said that Marshall acted out his time."
Donald Theall, read by Bob Dobbsreported
73

Cited for his largest claim and hedged in the same breath — the Illuminati lineage is kept as evidence for Canada's moment while its author's stake in it is named

Theall's most extravagant claim is repeated with its discount attached — Bob keeps the lineage from Egypt to Canada while noting Theall was inside the story he was telling.

"McLuhan's center was the new Illuminati, inheriting the whole tradition of the Illuminati going back to Egypt."
Donald Theall, read by Bob Dobbsreported

Connections

collaborator ofMarshall McLuhan

Daily intellectual exchange 1950–53 — Theall brought McLuhan the cybernetics literature and served as secretary on the McLuhan–Carpenter Ford grant application.

connects toFinnegans Wake

Theall's 1950–51 reading group is what Cameron credits as decisive in McLuhan's serious turn to Finnegans Wake.

connects toEric Havelock

The mid-50s Tennyson epyllion study Theall co-wrote with McLuhan makes no mention of Havelock, whose epyllion work preceded it.

connects toEdgar Cayce

McLuhan and Theall were reading "the world of kook" and looking into alchemy in the early 1950s.

connects toJohn Grierson

Theall hung out with Grierson in Montreal and got ill from the drinking; the camaraderie that Bob says Don survived and Grierson did not.

contrasted withJonathan Miller

Miller's 1971 attack and Theall's 1971 book came out together; the dialogue rates Theall's engagement far above Miller's.
