Utopia has long been another name for the unreal and the impossible. We have set utopia over against the world. As a matter of fact, it is our utopias that make the world tolerable to us: the cities and mansions that make people dream of are those in which they finally live. The more that men react upon their environment and make it over after a human pattern, the more continuously do they live in utopia; but when there is a breach between the world of affairs and the over world of utopia, we become conscious of the part that the will-to-utopia has played in our lives and we see our utopia as a separate reality.
