The controversial method of an opponent, distinguished from one's own by superior insincerity and fooling. This method is that of the later Sophists, a Grecian sect of philosophers who began by teaching wisdom, prudence, science, art and, in brief, whatever men ought to know, but lost themselves in a maze of quibbles and a fog of words. His bad opponent's "facts" he sweeps away, And drags his sophistry to light of day; Then swears they're pushed to madness who resort To falsehood of so desperate a sort. Not so; like sods upon a dead man's breast, He lies most lightly who the least is pressed. Polydore Smith
