In the Autumn issue of City Journal, the good doctor delivers a classic essay on the zeitgeist of our 21st-century Western world.
Cant is more destructive than hypocrisy because it is harder to expose and because a humbug deceives himself as well as others, while a mere hypocrite retains some awareness; he is a rogue rather than a villain. Cant is the vehement public expression of concern for others, or of anger at an opinion casting doubt on some moral orthodoxy that is not, and cannot be, genuinely felt, its vehemence being a shield for insincerity and lack of confidence in the orthodox opinion.
Leaders in cant are not inquirers after truth but seekers of power, if only the power to destroy, which is often a delight in itself. Cant is the weapon of the ambitious mediocrity, a class of person that has become much more numerous with the extension, but also dilution, of tertiary education. Such people believe that social prominence is their due.
