“The ironist is not bitter, he does not seek to undercut everything that seems worthy or serious, he scorns the cheap scoring-off of the wisecracker. He stands, so to speak, somewhat at one side, observes and speaks with a moderation which is occasionally embellished with a flash of controlled exaggeration. He speaks from a certain depth, and thus he is not of the same nature as the wit, who so often speaks from the tongue and no deeper. The wit’s desire is to be funny; the ironist is only funny as a secondary achievement.”
Robertson Davies, The Cunnng Man
