All ethics, all human action and all human thought, hang upon this one idea of unselfishness. The whole idea of human life can be put into that one word, unselfishness. Why should we be unselfish? Where is the necessity, the force, the power, of my being unselfish? You call yourself a rational man, a utilitarian; but if you do not show me a reason for utility, I say you are irrational. Show me the reason why I should not be selfish. To ask one to be unselfish may be good as poetry, but poetry is not reason. Show me a reason. Why shall I be unselfish, and why be good? Because Mr. and Mrs. So-and-so say so does not weigh with me. Where is the utility of my being unselfish? My utility is to be selfish if utility means the greatest amount of happiness. What is the answer? The utilitarian can never give it. The answer is that this world is only one drop in an infinite ocean, one link in an infinite chain. Where did those that preached unselfishness, and taught it to the human race, get this idea? We know it is not instinctive; the animals, which have instinct, do not know it. Neither is it reason; reason does not know anything about these ideas. Whence then did they come?
