 The view that intuitions are treated as evidence in philosophy has come under recent attack by a number of philosophers (Williamson 2007; Cappelen 2012; Deutsch 2015). The critics seem clearly to wish to deny that philosophical practice treats the having of an intuition as prima facie justification for its content, either because they deny that intuitions (at least as characterized by the sui generis accounts) exist or because they are skeptical that such states could serve as prima facie justification for their contents. Though Williamson, as noted above, suggests he cannot introspectively locate such states, Cappelen and Deutsch largely avoid introspective appeals, arguing instead that attention to philosophical practice and writing reveals little evidence of appeals to intuitions. Instead, they claim that close attention to influential discussions in philosophy reveals the ultimate source of justification for various claims is to be found in arguments.
