Could a world exist in which the nature of all the inhabitants would be so moral that the mere idea of what is immoral could not exist? Let me explain my question more in detail. Imagine a society in which the idea of dishonesty would not exist, because no person could be dishonest, a society in which the idea of unchastity could not exist, because no person could possibly be unchaste, a world in which no one could have any idea of envy, ambition or anger, because such passions could not exist, a world in which there would be no idea of duty, filial or parental, because not to be filial, not to be loving, not to do everything which we human beings now call duty, would be impossible. In such a world ideas of duty would be quite useless; for every action of existence would represent the constant and faultless performance of what we term duty. Moreover, there would be no difficulty, no pain in such performance; it would be the constant and unfailing pleasure of life. With us, unfortunately, what is wrong often gives pleasure; and what is good to do, commonly causes pain. But in the world which I am asking you to imagine there could not be any wrong, nor any pleasure in wrong-doing; all the pleasure would be in right-doing. To give a very simple illustration--one of the commonest and most pardonable faults of young people is eating, drinking, or sleeping too much. But in our imaginary world to eat or to drink or to sleep in even the least degree more than is necessary could not be done; the constitution of the race would not permit it. One more illustration. Our children have to be educated carefully in regard to what is right or wrong; in the world of which I am speaking, no time would be wasted in any such education, for every child would be born with full knowledge of what is right and wrong. Or to state the case in psychological language--I mean the language of scientific, not of metaphysical, psychology--we should have a world in which morality would have been transmuted into inherited instinct. Now again let me put the question: can we imagine such a world? Perhaps you will answer, Yes, in heaven--nowhere else. But I answer you that such a world actually exists, and that it can be studied in almost any part of the East or of Europe by a person of scientific training. The world of insects actually furnishes examples of such a moral transformation. It is for this reason that such writers as Sir John Lubbock and Herbert Spencer have not hesitated to say that certain kinds of social insects have immensely surpassed men, both in social and in ethical progress.
