The Danish physicist whose complementarity gives dialogue 23 its physics of the "third position." Bob retrieves, via Barry Nevitt, Bohr's aphorism that the opposite of a profound truth may be another profound truth; Cameron then routes Bohr's "superposition" — the uncertainty principle's "middle position of both together" — into McLuhan's tactility — his interior landscape — and the workings of quantum computing. Bohr is the bridge by which the dialogue's back-and-forth "you / not-you" is licensed as a real structure rather than mere confusion.
Across the dialogues
Enters as the physics behind the "third position" — his profound-truths aphorism and his superposition supply the archive its licence for two opposed truths at once, read as McLuhan's tactility
Bohr's aphorism supplies the dialogue its logic of non-contradiction — where a fact excludes its opposite, a "profound truth" does not, so two opposed truths can both hold; Cameron reads this as the collapse of the "you" whose perspective once fixed which of them was true.
"The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth."
Cameron routes Bohr into McLuhan — the uncertainty principle's "superposition," "the middle position of both together," is "what McLuhan calls tactility," and quantum computing computes faster precisely because it rests on it, "not tied to either or."
"uncertainty principle at the end of the day posits what's called a superposition."
Connections
Bob credits Barry Nevitt as the source who quoted Bohr's "two profound truths."
Cameron ties Bohr's superposition — "the middle position of both together" — to McLuhan's tactility and to quantum computing.
