Abstract

This textbook, oriented toward non-majors in philosophy, aims to provide an understanding not merely of forms of valid and invalid inference but also of the cognitive situation, of the methods of successful "problem-solving thought" and of the role of language therein. Great emphasis is thus placed on semiotics, which is integrated with the material from methodology and logic by considerations from general theory of knowledge. The whole presentation is marked by innovations, both pedagogical and theoretical. Most of the material of the usual course in elementary formal logic is crowded into the last part. The author has attempted, with some success, to develop a reformed "traditional" approach to logic in the light of the recent technical advances in semiotic and symbolic logic, without reducing it to a narrow and fragmentary formal exposition of these sciences. --L.
