Over the past two centuries the field of logic has developed at an explosive pace into new areas far removed from the traditional syllogism and formal proof. The purpose of this well-known introductory treatment is to chart, clearly and lucidly, this new domain of today's vastly sophisticated logic. Author Morris R. Cohen explores "the periphery of logic, the relations of logic to the rest of the universe, the philosophical presuppositions which give logic its meaning, and the applications which give it importance." Beginning with an exploration of the traditional scope of logic as the medium of formal proofs, the text pursues a modern investigation of the relationship between logic and the mind, logic and speech, logic in metaphor and fiction―and most significantly, logic and the concept of abstract reasoning as applied to the empirical world. Additional topics include logic and statistical method, probability, and scientific models. Concise and highly readable, this volume is suitable for college undergraduates and other readers interested in logic.
