Racism claims that the content of a man's mind (not his cognitive apparatus, but its content) is inherited; that a man's convictions, values and character are determined before he is born, by physical forces beyond his control. This is the caveman's version of the doctrine of innate ideas—or of inherited knowledge—which has been thoroughly refuted by philosophy and science. Racism is a doctrine of, by and for brutes. It is a barnyard or stock-farm version of collectivism, appropriate to a mentality that differentiates between various breeds of animals, but not between animals and men.
