Sophistry

noun

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
