ABSTRACT

Sometime in 1901 Charles S. Peirce began writing a treatise on logic, initially titled simply "Logic" and later "Minute Logic". Four long chapters were probably ready for the summer of 1902. By the end of the second chapter of the Minute Logic, Peirce has characterized logic as an anti-psychological normative logica docens that depends on mathematics, phenomenology, esthetics, and ethics and on which metaphysics and psychology depend. The plain identification of logic with semiotics that is sanctioned in the Minute Logic should not mislead us into thinking that all branches of logic as a whole are to be considered as concerned with signs in the same sense or to the same degree. In former versions of speculative grammar Peirce had considered the second trichotomy as a division of the third member of the first trichotomy, i.e., he had considered the division into terms, propositions, and arguments to be a division of symbols exclusively.
