Law of identity

The Law of Identity is a fundamental principle in classical logic and philosophy, often expressed succinctly as "A is A." This means that an object is identical to itself and that it possesses all the properties that define it. In other words, for any entity or proposition, it is identical to itself and distinct from any other entity or proposition. The Law of Identity can be formally stated as: - If something is true (or holds), then it is true (or holds).
