... I came fortunately upon Darwin’s and Spencer’s works “The Data of Ethics,” “First Principles,” “Social Statics,” “The Descent of Man.” Reaching the pages which explain how man has absorbed such mental foods as were favorable to him, retaining what was salutary, rejecting what was deleterious, I remember that light came as in a flood and all was clear. Not only had I got rid of theology and the supernatural, but I had found the truth of evolution. "All is well since all grows better” became my motto, my true source of comfort. Man was not created with an instinct for his own degradation, but from the lower he had risen to the higher forms. Nor is there any conceivable end to his march to perfection. His face is turned to the light; he stands in the sun and looks upward.

What, anyway, was he to say? That intelligence could surpass and excel the blind force of evolution, with its emphasis on mutation, struggle and death? That conscious cooperation was more efficient than feral competition?

Lamarck taught not only that species had been constantly undergoing changes from one geological period to another, but that there also had been a progressive advance of the organic world from the earliest to the latest times, from beings of the simplest to those of more and more complex structure and from the lowest instincts up to the highest, and, finally, from brute intelligence to the reasoning powers of Man. The improvement in the grade of being had been slow and continuous, and the human race itself was at length evolved out of the most highly organised and endowed of the inferior mammalia.

Part One... discusses at length the opposing ways of approaching and dealing with life: co-operating or competing. It traces the competitive spirit back to the animal kingdom and shows its gradual replacement by co-operation as humanity advances. Many of the problems of the modern world are seen in this context and co-operation is shown as the way, in line with our soul’s intent, to solve them.

I'm amused that Darwin, at whom I've been taking another look, should say that he also applies the ‘Malthusian’ theory to plants and animals, as though in Mr Malthus’s case the whole thing didn’t lie in its not being applied to plants and animals, but only — with its geometric progression — to humans as against plants and animals. It is remarkable how Darwin rediscovers, among the beasts and plants, the society of England with its division of labour, competition, opening up of new markets, ‘inventions’ and Malthusian ‘struggle for existence’. It is Hobbes’ bellum omnium contra omnes and is reminiscent of Hegel’s Phenomenology, in which civil society figures as an ‘intellectual animal kingdom’, whereas, in Darwin, the animal kingdom figures as civil society.

Therefore, he developed an ethical theory which had room both for instincts as well as the intellect. He said that man is not one but multiple; He is not one self, but a colony of selves. He must live all his selves and all his parts, and live them not moderately but fully.
