Obviously, it will not do to take our ideal from the principle in nature; for the simple reason that (except for some human or divine theory), there is no principle in nature. For instance, the cheap anti-democrat of to-day will tell you solemnly that there is no equality in nature. He is right, but he does not see the logical addendum. There is no equality in nature; also there is no inequality in nature. Inequality, as much as equality, implies a standard of value. To read aristocracy into the anarchy of animals is just as sentimental as to read democracy into it. Both aristocracy and democracy are human ideals: the one saying that all men are valuable, the other that some men are more valuable. But nature does not say that cats are more valuable than mice; nature makes no remark on the subject. She does not even say that the cat is enviable or the mouse pitiable. We think the cat superior because we have (or most of us have) a particular philosophy to the effect that life is better than death. But if the mouse were a German pessimist mouse, he might not think that the cat had beaten him at all. He might think he had beaten the cat by getting to the grave first. Or he might feel that he had actually inflicted frightful punishment on the cat by keeping him alive. Just as a microbe might feel proud of spreading a pestilence, so the pessimistic mouse might exult to think that he was renewing in the cat the torture of conscious existence. It all depends on the philosophy of the mouse. You cannot even say that there is victory or superiority in nature unless you have some doctrine about what things are superior. You cannot even say that the cat scores unless there is a system of scoring. You cannot even say that the cat gets the best of it unless there is some best to be got. We cannot, then, get the ideal itself from nature, and as we follow here the first and natural speculation, we will leave out (for the present) the idea of getting it from God. We must have our own vision. But the attempts of most moderns to express it are highly vague.
