„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.
It is not merely a short cut. It is all these things and something more. It is the guarantee of our self-respect; it is the projection upon the world of our own sense or our own value, our own position, and our own rights. [... ] They are the fortress of our traditions, and behind its defenses we can continue to feel ourselves safe in the position we occupy.“
