"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." (Marx to Engels, 18 June 1862)
