Forbes has the entirety of Ayn Rand’s essay “Racism.” Definitely worth a read.
Racism by Ayn Rand
Racism is the lowest, most crudely primitive form of collectivism. It is the notion of ascribing moral, social or political significance to a man’s genetic lineage—the notion that a man’s intellectual and characterological traits are produced and transmitted by his internal body chemistry. Which means, in practice, that a man is to be judged, not by his own character and actions, but by the characters and actions of a collective of ancestors.
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 factors 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.
Like every form of determinism, racism invalidates the specific attribute which distinguishes man from all other living species: his rational faculty. Racism negates two aspects of man’s life: reason and choice, or mind and morality, replacing them with chemical predestination.
The respectable family that supports worthless relatives or covers up their crimes in order to “protect the family name” (as if the moral stature of one man could be damaged by the actions of another)—the bum who boasts that his great-grandfather was an empire-builder, or the small-town spinster who boasts that her maternal great-uncle was a state senator and her third cousin gave a concert at Carnegie Hall (as if the achievements of one man could rub off on the mediocrity of another)—the parents who search genealogical trees in order to evaluate their prospective sons-in-law—the celebrity who starts his autobiography with a detailed account of his family history—all these are samples of racism, the atavistic manifestations of a doctrine whose full expression is the tribal warfare of prehistorical savages, the wholesale slaughter of Nazi Germany, the atrocities of today’s so-called “newly emerging nations.”
The theory that holds “good blood” or “bad blood” as a moral-intellectual criterion, can lead to nothing but torrents of blood in practice. Brute force is the only avenue of action open to men who regard themselves as mindless aggregates of chemicals.
