That absolutely new moral ideas should be developed by the moral imagination is for the theory of evolution no more inexplicable than the development of one animal species out of another, provided only that this theory, as a Monistic world-view, rejects, in morality as in science, every transcendent (metaphysical) influence. In doing so, it follows the same principle by which it is guided in seeking the causes of new organic forms in forms already existing, but not in the interference of an extra-mundane God, who produces every new species in accordance with a new creative idea through supernatural interference. Just as Monism has no use for supernatural creative ideas in explaining living organisms, so it is equally impossible for it to derive the moral world-order from causes which do not lie within the world. It cannot admit any continuous supernatural influence upon moral life (divine government of the world from the outside), nor an influence either through a particular act of revelation at a particular moment in history (giving of the ten commandments), or through God's appearance on the earth (Divinity of Christ [10]). Moral processes are, for Monism, natural products like everything else that exists, and their causes must be looked for in nature, i.e., in man, because man is the bearer of morality. Ethical Individualism, then, is the crown of the edifice that Darwin and Haeckel have erected for Natural Science. It is the theory of evolution applied to the moral life. Anyone who restricts the concept of the natural from the outset to an artificially limited and narrowed sphere, is easily tempted not to allow any room within it for free individual action. The consistent Evolutionist does not easily fall a prey to such a narrow-minded view. He cannot let the process of evolution terminate with the ape, and acknowledge for man a supernatural origin. Again, he cannot stop short at the organic reactions of man and regard only these as natural. He has to treat also the life of moral self-determination as the continuation of organic life. The Evolutionist, then, in accordance with his fundamental principles, can maintain only that moral action evolves out of the less perfect forms of natural processes. He must leave the characterisation of action, i.e., its determination as free action, to the immediate observation of each agent. All that he maintains is only that men have developed out of non-human ancestors. What the nature of men actually is must be determined by observation of men themselves. The results of this observation cannot possibly contradict the history of evolution. Only the assertion that the results are such as to exclude their being due to a natural world-order would contradict recent developments in the Natural Sciences. [11]
