The Principle of Identity

The Principle of Identity states that each thing is identical to itself; in other words, an object or concept is the same as itself and different from others. For example, if we say "a red apple" exists, then that specific apple is the same as itself and not something else. This principle underpins logical reasoning by ensuring consistency and clarity—recognizing that a thing's identity remains unchanged over time unless it undergoes a transformation. It’s a fundamental idea that helps us distinguish and understand objects, concepts, and statements in a coherent and consistent way.
