The Catholic veto upon usury, as defined in dogmatic councils, cuts across all classes. But it is absolutely necessary to the capitalist to distinguish more delicately between two kinds of usury; the kind he finds useful and the kind he does not find useful. The religion of the Servile State must have no dogmas or definitions. It cannot afford to have any definitions. For definitions are very dreadful things: they do the two things that most men, especially comfortable men, cannot endure. They fight; and they fight fair. – G. K. Chesterton, Utopia of Usurers and other Essays.
