ABSTRACT
Sometime in 1901 Peirce began writing a treatise on logic, initially titled simply “Logic” (R 1579) and later “Minute Logic” (R 1578). 1 Four long chapters were probably ready for the summer of 1902 (I. Intended Characters of this Treatise; II. Prelogical Notions; III. The Simplest Mathematics; IV. Ethics). In July 1902 he applied to the Carnegie Institution for a grant to bring his treatise to completion, confident that the book would put “before the world the result of [his] researches into logic,” results which “have never been published” but in “fragmentary papers” (RL 75 CSP 2 ISP 84). The grant was rejected, and the Minute Logic remained incomplete. 2
