The question of how consciousness and self-awareness connect with personal identity has accompanied philosophy since antiquity. Sages of diverse orientations have put forth various elaborate answers, showing among other things that self-awareness is more than just being conscious. The ensouled matter of the self-conscious brain still poses deeply puzzling questions about individual identity, and nowadays the new reality of anthropo-technology once again poses the question how we can know about ourselves. ‘ “Who am I?” Identity in philosophy’ considers the concept of identity in philosophy through time and the mind–body problem. It also discusses empiricist reductionism, mentalist essentialism, ordinary language analysis, and interactionism.
