Laws of thought, 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 law of non-contradiction is a rule of logic. It states that if something is true, then the opposite of it is false. For example, if an animal is a cat, the same animal cannot be not a cat. Or, stated in logic, if +p, then not -p, +p cannot be -p at the same time and in the same sense.
There are three laws upon which all logic is based, and they're attributed to Aristotle. These laws are the law of identity, law of non-contradiction, and law of the excluded middle. According to the law of identity, if a statement is true, then it must be true.
