Note 48 — VII THE LOGICAL CHARACTER OF IDEAS
Reading edition
This conception of "consciousness" as a sort of reduplicate world of things comes to us, I think, chiefly from Hume's conception that the "mind is nothing but a heap, a collection of different perceptions, united together by certain relations."—Treatise of Human Nature, Book I, Part IV, sec. 2. For the evolution of this sort of notion out of the immaterial substance notion, see Bush, "A Factor in the Genesis of Idealism," in the James Festschrift.
