Those who are guilty of the argumentum ad ignorantiam profess belief in something because its opposite cannot be proved … In the realm where “prejudice” is now most an issue, it normally takes a form like this: you cannot prove by the method of statistics and quantitative measurement that men are not equal. Therefore all men are equal. … You cannot prove again by the methods of science that one culture is higher than another. Therefore the culture of the Digger Indians is just a good as that of Muncie, Indiana, or thirteenth-century France.
