Chapter Two, Part Eight: The Three “Basic” Laws of Logic and How They Affect Reasoning

The three basic laws of logic are:
. The Law of Identity.
. The Law of Non-Contradiction.
. The Law of Excluded Middle.

The law of identity institutionalizes the prevailing theory of nature stating that every member of a class, say class X, has the same nature as every other member of that class. From this we can conclude that every member of that class is, by nature, X, and only X. In symbolic terms, this simply means that X is X.

As obvious as X is X may appear, its consequences are not. The law of identity justifies generalizations, and therefore, the concept that reasoning in terms of absolutes and certainty is logical. If everyone agrees that X is X and only X, it is reasonable to generalize, and be absolutely certain, that every X is X.
