Introduction

1. Definition of Logic. -- Logic is the systematic study of the order to be observed in judging, reasoning, and other processes of thought in order to arrive at the knowledge of truth. This definition shows us:

(1) the materials (material cause) of the logical order;

(2) their elaboration (formal cause)

(3) the purpose of this elaboration (final cause).
