If a theory justifies the false position which a certain part of society is in, then, however baseless and even obviously false the theory may be, it will get adopted and become the belief of that part of society…However baseless theories of this sort may be, however contradictory they may be to everything mankind knows and recognizes, however obviously immoral they may be, they are accepted on faith, without criticism, and are preached with passionate enthusiasm, sometimes for centuries, until the conditions they justify are done away with or the absurdity of the theories becomes too obvious.
