Logic is the science that explains what conditions must be fulfilled in order that a proposition may be proved, if it admits of proof. When propositions are expressed with the universality and definiteness that belong to scientific statements, they are called laws; and laws, so far as they are not laws of quantity, are tested by the principles of Logic, if they at all admit of proof.

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. Logic is the theory of the mind's rational processes.

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.
by Lewis Carroll - Macmillan and co
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.
