Thus the Socialists prove that, different from the animal world, the competitive struggle existing between men does not bring forth the best and most qualified, but destroys many strong and healthy ones because of their poverty, while those that are rich, even if weak and sick, survive. Socialists prove that personal strength is not the determining factor, but it is something outside of man; it is the possession of money that determines who shall survive and who shall perish.
VI. NATURAL LAW AND SOCIAL THEORY.
The false conclusions reached by Haeckel and Spencer on Socialism are no surprise. Darwinism and Marxism are two distinct theories, one of which applies to the animal world, while the other applies to society. They supplement each other in the sense that, according to the Darwinian theory of evolution, the animal world develops up to the stage of man, and from then on, that is, after the animal has risen to man, the Marxian theory of evolution applies. When, however, one wishes to carry the theory of one domain into that of the other, where different laws are applicable, he must draw wrong inferences.
Such is the case when we wish to ascertain from natural law what social form is natural and applicable, and this is just what the bourgeois Darwinists did. They drew the inference that the laws which govern in the animal world, where the Darwinian theory applies, apply with equal force in the capitalist system, and that therefore capitalism is a natural order and must endure forever. On the other hand, there were
