theory of identity

The theory of identity explores what makes a person or thing fundamentally themselves over time. It asks how we remain the same individual despite changes, and what core qualities define our unique essence. Think of identity as the underlying "who" or "what" that stays consistent, such as memories, personality, or biological traits, even as we grow or experience change. Philosophers examine different aspects—like physical continuity or psychological connections—to understand what contributes to our sense of self and personal continuity throughout life.
