A Treatise of Formal Logic: its Evolution and Main Branches, with its Relations to Mathematics and Philosophy

Abstract

OF all the branches of philosophy, logic alone has had the distinction of being claimed by the exact sciences as one of them. The event is of recent occurrence; in fact, it has happened only since logic has taken to mathematical symbolism. So long as logic reigned over philosophical logomachies, it was scarcely differentiated from normative philosophy; and it has cost a great deal of hard thinking to bring it by degrees within the favours of the exact sciences. Why logic slumbered in the linguistic bliss devised by Aristotle's genius, and how it was awakened to a nobler destiny, is a story of great importance and interest for the student of mental sciences. It is this story which Prof. Jørgensen tells us in his present work, in which real scholarship is happily federated with the easier ways of education.
