XII. Moral Imagination Darwinism and Morality
That absolutely new moral Ideas should be developed by the moral imagination is for the theory of evolution no more miraculous 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 which cannot be ideally experienced. In doing so, it follows the same principle by which it is guided in seeking the causes of new organic forms without referring to the interference of an extra-mundane Being, who produces every new species in accordance with a new creative thought through supernatural influence. Just as Monism has no use for supernatural creative thoughts 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 of our experience. It cannot admit that the nature of moral will is exhausted by being traced back to a continuous supernatural influence upon moral life (divine government of the world from the outside), or a particular act of revelation at a particular moment in history (giving of the ten commandments), or through God's appearance on the earth (as Christ). All that happens in this way to and in man becomes a moral element only when it enters into human experience and becomes an individual's own. Moral processes are, for Monism, products of the world like everything else that exists, and their causes must be looked for in the world, i.e., in man, because man is the bearer of morality.
