Some would maintain the normative character of moral laws at least in the sense that Ethics is to be taken as a kind of dietetic which, from the conditions of the organism's life, deduces general rules, on the basis of which it hopes to give detailed directions to the body (Paulsen, System der Ethik). This comparison is mistaken, because our moral life cannot be compared with the life of the organism. The behaviour of the organism occurs without any volition on our part. Its laws are fixed data in our world; hence we can discover them and apply them when discovered. Moral laws, on the other hand, do not exist until we create them. We cannot apply them until we have created them. The error is due to the fact that moral laws are not at every moment new creations, but are handed down by tradition. Those which we take over from our ancestors appear to be given like the natural laws of the organism. But it does not follow that a later generation has the right to apply them in the same way as dietetic rules. For they apply to individuals, and not, like natural laws, to specimens of a genus. Considered as an organism, I am such a generic specimen, and I shall live in accordance with nature if I apply the laws of my genus to my particular case. As a moral agent I am an individual and have my own private laws. [9] The view here upheld appears to contradict that fundamental doctrine of modern Natural Science which is known as the Theory of Evolution. But it only appears to do so. By evolution we mean the real development of the later out of the earlier in accordance with natural law. In the organic world, evolution means that the later (more perfect) organic forms are real descendants of the earlier (imperfect) forms, and have grown out of them in accordance with natural laws. The upholders of the theory of organic evolution believe that there was once a time on our earth, when we could have observed with our own eyes the gradual evolution of reptiles out of Proto-Amniotes, supposing that we could have been present as men, and had been endowed with a sufficiently long span of life. Similarly, Evolutionists suppose that man could have watched the development of the solar system out of the primordial nebula of the Kant-Laplace hypothesis, if he could have occupied a suitable spot in the world-ether during that infinitely long period. But no Evolutionist will dream of maintaining that he could from his concept of the primordial Amnion deduce that of the reptile with all its qualities, even if he had never seen a reptile. Just as little would it be possible to derive the solar system from the concept of the Kant-Laplace nebula, if this concept of an original nebula had been formed only from the percept of the nebula. In other words, if the Evolutionist is to think consistently, he is bound to maintain that out of earlier phases of evolution later ones really develop; that once the concept of the imperfect and that
