careful of this theory," he said to the Darwinists, "for this theory is very nearly related to the theory that caused so much dread in our neighboring country." This allusion to the Paris Commune, made in the year famous for the hunting of Socialists, must have had a great effect. What shall be said, however, about the science of a professor who attacks Darwinism with the argument that it is not correct because it is dangerous! This reproach, of being in league with the red revolutionists, caused a lot of annoyance to Haeckel, the defendant of this theory. He could not stand it. Immediately afterwards he tried to demonstrate that it is just the Darwinian theory that shows the untenableness of the Socialist demands, and that Darwinism and Socialism "endure each other as fire and water."
Let us follow Haeckel's contentions, whose main thoughts re-occur in most authors who base their arguments against Socialism on Darwinism.
Socialism is a theory which presupposes natural equality for people, and strives to bring about social equality; equal rights, equal duties, equal possessions and equal enjoyments. Darwinism, on the contrary, is the scientific proof of inequality. The theory of descent establishes the fact that animal development goes in the direction of ever greater differentiation or division of labor; the higher or more perfect the animal, the greater the inequality existing. The same holds also good in society. Here, too, we see the great division of labor between vocations, class, etc., and the higher we stand in social development the greater become the inequalities in strength, ability and faculty. The theory of descent is therefore to be recommended
