You are, first of all, intelligence, was Socrates’ reply. It is your reason that makes you human; that enables you to be more than a mere bundle of desires and wishes; that makes you a self-sufficient individual and entitles you to claim that you are an end in yourself. Socrates’ saying ‘care for your souls’ is largely an appeal for intellectual honesty, just as the saying ‘know thyself’ is used by him to remind us of our intellectual limitations.
