I like to imagine a person's psyche to be like a boardinghouse full of characters. The ones who show up regularly and who habitually follow the house rules may not have met other long-term residents who stay behind closed doors, or who only appear at night. An adequate theory of character must make room for character actors, for the stuntmen and animal handlers, for all the figures who play bit parts and produce unexpected acts. They often make the show fateful, or tragic, or farcically absurd.
