LOGIC

The study of the methods and principles used to distinguish Good (correct) Reasoning from Bad (incorrect)Reasoning is 

called LOGIC. How logical are we ?

* If truth is to be sought in every division of Philosophy, we must , before all else, possess trustworthy principles

   and methods for the discernment of truth. Now the logical branch is that which includes the theory of criteria                       

   and of proofs; so it is with this that we ought to make our beginnings.

                                                                                                     --Sextus Empiricus.

*All reasoning is thinking, but not all thinking is reasoning.

*Logic cannot be "the" science of the laws of thought, because psychology is also a science which deals with

  laws of thought(among other things). And Logic is not a branch of psychology; it is a separate and distinct 

  field of study.

*One may remember something, or imagine it, without doing any reasoning about it. Or one may let his       thoughts

   "drift along" in a day dream or a reverie, building castles in the air, or following what psychologists call

    Free Association, in which one image is replaced by another in an order that is anything but logical. There

    is often great significance to the sequence of thoughts in such Free Association, and some psychiatric tech-

   -iques make use of it. One need not be a psychiatrist to gain insight into a person's character by observing

    the flow of his stream of consciosness.   
* The distinction between correct and incorrect reasoning is the central problem with which logic deals.
   The logician's methods and techniques have been developed primarily for the purpose of making this 
   distinctions clear. The logician is interested in all reasoning regardless of its subject matter but only
   from  this special point of view.
