Abstract

This chapter deals with one of the common fallacies in Western philosophy: ad hominem: tu quoque. An ad hominem: tu quoque argument is often seen in political debate. As Walton stresses: “The primary case of the tu quoque type of ad hominem retort occurs when an ad hominem reply is used to respond to an ad hominem attack”. As with all the ad hominem argument forms, the ad hominem: tu quoque has both fallacious and legitimate uses. Fallacious uses of the ad hominem argument type are pernicious, in part, because of how difficult it can be to respond to them in an effective way. One of the main issues with ad hominem arguments is telling which are fallacious and which are not. The chapter looks at some examples to illustrate the use of proponent's ad hominem, and respondent's ad hominem.
