When you say, "I am a person," the word person is from the drama. When you open a play script and see the list of the actors, this is the dramatis personae, the persons of the drama. The word person in Latin is per-sona, meaning "through sound," or something through which sound comes; the persona in Greek or Roman drama was the mask worn by the actors. and because they acted on an open-air stage, the mask's mouth was shaped like a small megaphone that would project the sound. So the person is the mask. Isn't it funny how we have forgotten that?

...But if you forget that you are the actor, and think you are the person, you have been taken in by your own role.

Alan Watts, "The Images of Man" (1996)
