Tu quoque

From Wikipedia, the free encyclopedia

This article is about the logical fallacy. For the historical quotation "Tu quoque, Brute, fili mi", see Et tu, Brute?. For the play by John Cooke, see Greene's Tu Quoque.

Tu quoque /tuːˈkwoʊkwiː/,^[1] (Latin for "you, too" or "you, also") or the appeal to hypocrisy, is a logical fallacy that attempts to discredit the opponent's position by asserting the opponent's failure to act consistently in accordance with that position; it attempts to show that a criticism or objection applies equally to the person making it. This dismisses someone's point of view based on criticism of the person's inconsistency and not the position presented^[2] whereas a person's inconsistency should not discredit the position. Thus, it is a form of the ad hominem argument.^[3] To clarify, although the person being attacked might indeed be acting inconsistently or hypocritically, this does not invalidate their argument.
