Practical Logic

The present book is an elementary textbook on logic for university undergraduates. It is intended mainly for students of law. The volume contains the fundamental knowledge in the field of semiotics and in the field of formal logic and general methodology of sciences. Semiotics formal logic and the general methodology of sciences are jointly called by the name of logic in the widest sense of the word. The selection of materials from these fields and of supplementary information concerning other adjacent branches of knowledge has been made primarily with a view to making more evident and contributing to the mastery of those skills useful in practice for the thinking processes of lawyers. This does not mean that the whole subject matter has been restricted to a choice of examples that might in one way or another be connected with juridical problems. In any cases such examples might not always be the most appropriate in view of their complicated character. The final part of the textbook contains the presentation of some specifically juridical applications of logic and an analysis of the intellectual activities of lawyers. The first two parts constitute however an independent entity and may be used as an elementary textbook on logic for students of various branches of the humanities.
