Logic Made Simple

The foundation of logic was laid by Aristotle in the 4th century B.C. i.e. called Aristotelian Logic. Etymologically, the termLogic came from the Greek word 'Logos' means discourse of thought. But any thought is not an object of the study of logic because thinking is one of the processes studied by psychologists. Logic is not concerned with the thinking process. It is not a branch of psychology. Logic studies only that variety of thinking which is called 'Inference'( Reasoning or Argument ).
