Logic

Logic brings elementary logic out of the academic darkness into the light of day and makes the subject fully accessible. Paul Tomassi writes in a patient and user-friendly style which makes both the nature and value of formal logic crystal clear. The reader is encouraged to develop critical and analytical skills and to achieve a mastery of all the most successful formal methods for logical analysis. This textbook proceeds from a frank, informal introduction to fundamental logical notions, to a system of formal logic rooted in the best of our natural deductive reasoning in daily life. As the book develops, a comprehensive set of formal methods for distinguishing good arguments from bad is defined and discussed. In each and every case, methods are clearly explained and illustrated before being stated in formal terms.
