A. MS. notebook
Published, in part, as 1.611-615 and 8.176 (except 176n3) (pp. 37-49 and 51-53). Unpublished: criticism of Sigwart and the notion of "logisches Gef,hl." Logic embraces methodeutic, critic, and the doctrine of signs (speculative grammar), with the ultimate purpose of the logician being the working out of a theory regarding the advancement of knowledge. Speculative grammar is neither psychology nor epistemology. Erkenntnislehre is mainly metaphysics. CSP agrees with those metaphysicians who insist that metaphysics must rest upon logic.
