"In the immense sphere of living things, the obvious rule is violence, a kind of inevitable frenzy which arms all things in mutua funera. Once you leave the world of insensible substances, you find the decree of violent death written on the very frontiers of life. Even in the vegetable kingdom, this law can be perceived: from the huge catalpa to the smallest of grasses, how many plants die and how many are killed! But once you enter the animal kingdom, the law suddenly becomes frighteningly obvious. A power at once hidden and palpable appears constantly occupied in bringing to light the principle of life by violent means. In each great division of the animal world, it has chosen a certain number of animals charged with devouring the others; so there are insects of prey, reptiles of prey, birds of prey, fish of prey, and quadrupeds of prey. There is not an instant of time when some living creature is not devoured by another [...] Thus is worked out, from maggots up to man, the universal law of the violent destruction of living beings. The whole earth, continually steeped in blood, is nothing but an immense altar on which every living thing must be sacrificed without end, without restraint, without respite until the consummation of the world, the extinction of evil, the death of death."
