"Whatever virtues a triumphant egoism really leads to, no one can reasonably pretend that it leads to knowledge."

...humility has infinitely deeper roots than any modern men suppose; that it is a metaphysical and, one might almost say, a mathematical virtue. Probably this can best be tested by a study of those who frankly disregard humility and assert the supreme duty of perfecting and expressing one's self. These people tend, by a perfectly natural process, to bring their own great human gifts of culture, intellect, or moral power to a great perfection, successively shutting out everything that they feel to be lower than themselves. Now shutting out things is all very well, but it has one simple corollary—that from everything that we shut out we are ourselves shut out. When we shut our door on the wind, it would be equally true to say that the wind shuts its door on us. Whatever virtues a triumphant egoism really leads to, no one can reasonably pretend that it leads to knowledge. Turning a beggar from the door may be right enough, but pretending to know all the stories the beggar might have narrated is pure nonsense; and this is practically the claim of the egoism which thinks that self-assertion can obtain knowledge. A beetle may or may not be inferior to a man—the matter awaits demonstration; but if he were inferior by ten thousand fathoms, the fact remains that there is probably a beetle view of things of which a man is entirely ignorant. If he wishes to conceive that point of view, he will scarcely reach it by persistently revelling in the fact that he is not a beetle. The most brilliant exponent of the egoistic school, Nietszche, with deadly and honourable logic, admitted that the philosophy of self-satisfaction led to looking down upon the weak, the cowardly, and the ignorant. Looking down on things may be a delightful experience, only there is nothing, from a mountain to a cabbage, that is really seen when it is seen from a balloon. The philosopher of the ego sees everything, no doubt, from a high and rarified heaven; only he sees everything foreshortened or deformed.
