Quote from ‘A Brief Intellectual Autobiography by Charles Sanders Peirce’


Logic […] studies the relation of the phenomenon to the essential character of the phenomenon as controllable, that is, its reasonableness, or embodying an idea. That which embodies an idea is a sign, and it is best to make logic the science of the general properties of signs.

Peirce, 1983, p. 71; MS [R] L107:20-21
