The philosopher Bob Dobbs puts at the origin of what McLuhan called the second Copernican revolution — the turn inward that discovers acoustic space. In dialogue 65 he is the point where the session's philosophical genealogy begins: Hegel, Fichte and Schelling are all described as working out problems he left. New to him — dialogue 65.
Across the dialogues
Installed as the hinge between McLuhan and German idealism — Bob credits him with the second Copernican revolution and Cameron makes everyone after him an heir to one set of problems
Kant is given credit for the discovery McLuhan built on, which relocates acoustic space from anthropology into the history of philosophy.
"what about Marshall McLuhan second Copernican revolution, which is Kant discovering inner or acoustic space?"
The idealists are defined by inheritance rather than doctrine — which is what lets Cameron treat them as one movement without flattening their differences.
"everybody after Kant had certain problems that they had to figure out."
