Homunculus: A metaphorical little man (or little woman) who resides in your cranial noggin and pulls the levers for your behavior. Also called self, ego, muse, conscience, and Jiminy Cricket. Homunculi are usually quite reasonable, and can be influenced by your spouse, psychotherapist, preacher, and tiny little angels and devils that stand on each of your shoulders, dispensing advice.
Homunculi are generally rejected by behaviorists, but hey, they're extinct anyways!
