"The order of castes," said Nietzsche, "is the dominating law of nature, against which no merely human agency may prevail. In every healthy society there are three broad classes, each of which has its own morality, its own work, its own notion of perfection and its own sense of mastery. The first class comprises those who are obviously superior to the mass intellectually; the second includes those whose eminence is chiefly muscular, and the third is made up of the mediocre. The third class, very naturally, is the most numerous, but the first is the most powerful. "To this highest caste belongs the privilege of representing beauty, happiness and goodness on earth.... Its members accept the world as they find it and make the best of it.... They find their happiness in those things which, to lesser men, would spell ruin--in the labyrinth, in severity toward themselves and others, in effort. Their delight is self-governing: with them asceticism becomes naturalness, necessity, instinct. A difficult task is regarded by them as a privilege; to play with burdens which would crush others to death is their recreation. They are the most venerable species of men. They are the most cheerful, the most amiable. They rule because they are what they are. They are not at liberty to be second in rank. "The second caste includes the guardians and keepers of order and security--the warriors, the nobles, the king--above all, as the highest types of warrior, the judges and defenders of the law. They execute the mandates of the first caste, relieving the latter of all that is coarse and menial in the work of ruling. "At the bottom are the workers--the men of handicraft, trade, agriculture and the greater part of art and science. It is the law of nature that they should be public utilities--that they should be wheels and functions. The only kind of happiness of which they are capable makes intelligent machines of them. For the mediocre, it is happiness to be mediocre. In them the mastery of one thing--_i.e._ specialism--is an instinct. "It is unworthy of a profound intellect to see in mediocrity itself an objection. It is, indeed, a necessity of human existence, for only in the presence of a horde of average men is the exceptional man a possibility.... "Whom do I hate most among the men of today? The socialist who undermines the workingman's healthy instincts, who takes from him his feeling of contentedness with his existence, who makes him envious, who teaches him revenge.... There is no wrong in unequal rights: it lies in the vain pretension to equal rights."[1]
