The systems of stereotypes may be the core of our personal tradition, the defenses of our position in society. They are an ordered more or less consistent picture of the world, to which our habits, our tastes, our capacities, our comforts and our hopes have adjusted themselves. They may not be a complete picture of the world, but they are a picture of a possible world to which we are adapted. In that world, people and things have their well-known places, and do certain expected things. We feel at home there. We fit in. We are members.
