PRAGMATISM (MS 279-335)
A note appended to notebook reads: "Rejected. No time for this and it would need two if not three lectures." The history and nature of mathematics. Role of diagrams in mathematics. Algebra of logic as an attempt to analyze mathematical reasoning into its logical steps. An aside on opium's "dormitive virtue": a sound doctrine but hardly an explanation. The nature of abstraction, especially mathematical abstraction. Role played by conception of collection in mathematics. Whether pure mathematics is a branch of logic. "I am satisfied that all necessary reasoning is of the nature of mathematical reasoning." Boolean algebra.
