Abstract: Evidentialism is the view that evidence alone determines rational belief. Recently, several rivals to evidentialism have been defended, including pragmatic and moral encroachment, epistemic partiality, and practical and moral reasons for belief. Call these rivals “impurist” views. While impuirst views have both compelling cases and interesting arguments in their favor, they also face a number of serious challenges. In this paper, I explain three of the most important challenges to impurism. Then I argue that, by embracing epistemic permissivism, impurists can hold onto what’s central to their views while dealing with all three of these challenges. Finally, I suggest that the evidentialist should also embrace permissivism, as it helps them better respond to the most compelling considerations in favor of impurism.
