Abstract
Another beginners' text, emphasizing the problem of the relation between ordinary language and formal logic. From an exceedingly simplified introduction to semiotics, it moves through an analysis of conventions of ordinary English discourse to a presentation of an elementary non-standard symbolic propositional, class and modal logic. A matrix method is used throughout, facilitating the use of the same symbols for class and propositional relations. Chapters are included on probability, Mill's inductive methods, and logic and scientific method. Abundant, typically dull exercises are provided.--L. K. B.
