ABSTRACT

Originally published in 1930, this well-known text by the late British philosopher Abraham Wolf offers the student a practical, consistent, and comprehensive approach to logic which remains unique in its field. Dr. Wolf here deals systematically with the two main types of reasoning - formal logic and inductive logic - and their various applications. All the main elements of logic - such as inference, syllogism, dilemmas, evidence, deductive and inductive methods, and probability - are subsumed under these general headings.

Professor Wolf strongly emphasizes the fact that logic cannot be mastered without some practical application; at the end of this volume, therefore, he includes a section of exercises based on each chapter. His unusally interesting appendix examines such matters as symbolic as logic, fallacies, the law of contradiction, modal propositions, the existential import of categorical propositions, predictables, and categories.
