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.

Chapter Two, Part Seven: What is the Assumption Upon Which Logic Rests?

Many consider Plato’s Theory of Noncontradiction, “the axiom [or basic assumption beneath] … all logic” ; namely “the same thing clearly cannot act or be acted upon in the same part or in the same relation to the same thing at the same time, in contrary ways: and therefore whenever this contradiction occurs in things apparently the same, we know that they are really not the same but different.”

Plato’s theory seems self-evident, but shortly we will see that it is not.

Introducing Shots of Awe

It’s a pleasure to showcase this content from the Shots of Awe YouTube channel. The video featured here entitled “Nonconformity and the Creative Life” is a great introduction, and here’s more of a description from the creators themselves.

“Ever ponder the miracle of life? Or perhaps wonder about the evolution of intelligence? In Shots of Awe, ‘Performance Philosopher’ Jason Silva chases his inspiration addiction as he explores these topics and more. Every week Jason freestyles his way into the complex systems of society, technology and human existence and discusses the truth and beauty of science in a form of existential jazz.
