Every gain entails some loss—this is the law of the world in which human beings exist. A total or perfect gain in any intellectual, political, or material activity is unattainable. But this implies that man is incapable of creating a perfect civilization in which man may achieve his full potentialities—the idea of a manmade earthly heaven is a utopian dream. Whenever a civilization makes a gain in one area, it’s beset with loss in another area. A civilization can succeed in some of the things, but no civilization can succeed in everything. Nature, in its infinite wisdom, has not equipped mankind with the faculties for creating a civilization free of contradictions and conflicts.
