Principles of Logic
by George Hayward Joyce
Publisher: Longmans 1908
Number of pages: 464
This work is an attempt at a presentment of what is frequently termed the Traditional Logic, and is intended for those who are making acquaintance with philosophical questions for the first time. Yet it is impossible to deal with logical questions save in connection with definite metaphysical and epistemological principles. Logic, as the theory of the mind's rational processes in regard of their validity, must necessarily be part of a larger philosophical system.

Here you see Carroll the mathematician at his playful best. This isn't about modern symbolic logic but about ways of expressing classical logic with symbols. It's loaded with amusing problems to delight any mathematical puzzler.

In undertaking the investigations summarized in this volume, the author's chief aim was to explain the origin of Logic by a psychological study of the first logician. This required a knowledge of the chronology of Plato's writings.
