Laws of Logic

Strong's Concordance


Webster Definition


traditionally, the three fundamental laws of logic:

(1) the law of contradiction,

(2) the law of excluded middle (or third), and

(3) the principle of identity.

The second primary law of logic is the principle of excluded middle. The law of (non-)contradiction simply states that A cannot equal or be non-A

The third primary law of logic is called the law of identity. It states that A=A or that "if any statement is true, then it is true
