Laws Of Thought

The laws of thought are fundamental axiomatic rules upon which rational discourse itself is based.

The rules have a long tradition in the history of philosophy and logic.

They are laws that guide and underlie everyone’s thinking, thoughts, expressions, discussions, etc.

The laws of thought can be most intelligibly expressed thus:

Everything that is, exists.  [Law Of Identity]

Nothing can simultaneously be and not be. [Law Of Non-Contradiction]

Each and every thing either is or is not. [Law Of Excluded Middle]

Logic Is Transcendental

Logic is not a body of doctrine, but a mirror-image of the world.

Logic is transcendental.
