Origin
Cicero built the idea in his essay on friendship. A true friend, he writes, is as it were a second self — alter idem — and the whole point of such a friendship is that you can say anything to the other person because there is no meaningful gap between you.
The Latin tag alter ego, the other I, is a later formulation of the same thought, and for centuries it meant exactly what Cicero meant: your closest confidant, the person who can act for you. Some legal systems still use it that way, for someone empowered to stand in your place.
The modern sense turns it inward. An alter ego is now usually a second version of the same person — a stage name, a pen name, a character an author writes through, or the costumed identity that a comic-book hero puts on when the day job ends.
