the tribal Idealism of Plato and Aristotle was exalted as a kind of Christianity before Christ. Indeed, this is the source of the immense authority of Plato and Aristotle, even in our own day, that their philosophy was adopted by medieval authoritarianism. But it must not be forgotten that, outside the totalitarian camp, their fame has outlived their practical influence upon our lives. And although the name of Democritus is seldom remembered, his science as well as his morals still live with us.
