When you want to organize knowledge. you will be careful to base the classification upon essential qualities. You will thus derive classes in which the members have the greatest amount of resemblance to one another and the greatest amount of difference from the members of other classes. But suppose that, instead of organizing knowledge, you set out to organize ignorance and prejudice. You will then do precisely the opposite...You will keep the classification vague and flexible, so that it can be made to include just whatever individuals you choose.

The continuous disasters of man's history are mainly due to his excessive capacity and urge to become identified with a tribe, nation, church or cause, and to espouse its credo uncritically and enthusiastically, even if its tenets are contrary to reason, devoid of self-interest and detrimental to the claims of self-preservation.We are thus driven to the unfashionable conclusion that the trouble with our species is not an excess of aggression, but an excess capacity for fanatical devotion.

Since the social victim has been oppressed by society, he comes to feel that his individual life will be improved more by changes in society than by his own initiative. Without realizing it, he makes society rather than himself the agent of change.

We shall assume that what each man does is based not on direct and certain knowledge, but by pictures made by himself or given to him. If his atlas tells him the world is flat he will not sail near what he believes to be the edge of our planet for fear of falling off. If his maps include a fountain of eternal youth, a Ponce de Leon will go off in quest of it. If someone digs up yellow dirt that looks like gold, he will for a time act exactly as if he has found gold. The way in which the world is imagined determines at any particular moment what men will do. It does not determine what they will achieve. It determines their effort, their feelings, their hopes, not their accomplishments and results.
