The Laws of Thoughts are the fundamental axioms of rational logic as it is practised by humans. They are of specific interest to philosophers and logicians alike.

A violation of these laws is either impossible or paradoxical. Many logic puzzles hinge around these properties of logic.

## Law of Identity

Whatever is, is.

\[ \left ( P = P \right ) \forall P \]

## Law of Non-Contradiction

Nothing can be and not be.

\[ \sim \left ( P = ( \sim P ) \right ) \forall P \]

## Law of Excluded Middle

Everything must be or not be.

\[ \left ( P \lor ( \sim P ) \right ) \forall P \]
