Professor Aikins writes: "Thus, in so far as logic tries to make us reason correctly by giving us correct conceptions of things and the way in which their relations involve each other, it is a kind of simple metaphysics studied for a practical end."

Professor Creighton says, "Although in treating the syllogistic logic I have followed to a large extent the ordinary mode of presentation, I have both here, and when dealing with the inductive methods, endeavored to interpret the traditional doctrines in a philosophical way, and to prepare for the theoretical discussions of the third part of the book."

John Stuart Mill tried not to be metaphysical; but let the reader examine, say, his third chapter, "Of the Things denoted by Names," or look over Book VI, in his "System of Logic."

Professor Sigwart's great work, "Logik" (Freiburg, 2d edition, Volume I, 1889, Volume II, 1893), may almost be called a philosophy of logic.
