Excerpt from Deductive LogicOne critic, who was kind enough to look at this book in manuscript, recommended me to abandon the design of publishing It on the ground that my logic was too like all other logics another suggested to me to cut out a considerable amount of new matter. The latter advice I have followed, the former has encouraged me to hope that I shall not be considered guilty of wanton innovation. The few novelties which I have ventured to retain will, I trust, be regarded as legitimate extensions of received lines of teaching.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
