Apophasis is a rhetorical device wherein the speaker or writer brings up a subject by either denying it, or denying that it should be brought up. Accordingly, it can be seen as a rhetorical relative of irony. Also called "paralipsis," apophasis is usually employed to make a subversive ad hominem attack, which makes it a frequently used tactic in political speeches to make an attack on one's opponent. Using apophasis in this way is often considered to be bad form.The device is typically used to distance the speaker from unfair claims, while still bringing them up. For instance, a politician might say, "I don't even want to talk about the allegations that my opponent is a drunk." It can also be used in denying such claims entirely, for example by saying "I'm sure that my opponent is not lying; however, his grasp of the facts seems to be shaky."
