Abstract
A special version of arguments from hypocrisy, those known as tu quoque arguments, is introduced and developed. These are arguments from what one’s opponent would do, were conditions different, so they are what we call subjunctive tu quoque arguments. Arguments of this form are regularly taken to be fallacious, but the authors discuss conditions for determining when hypothetical inconsistency is genuinely relevant to criticizing a speaker’s assertion or proposed action and when it is not relevant.
