The city is a cultural invention enforcing on the citizen knowledge of his own nature. And this we do not like. That we are aggressive beings, easily given to violence; that we get along together because we must more than because we want to, and that the brotherhood of man is about as far from reality today as it was two thousand years ago; that reason's realm is small; that we never have been and never shall be created equal; that if the human being is perfectible, he has so far exhibited few symptoms - all are considerations of man from which space tends to protect us.
