 On the religion in politics literature, see the entry on  religion and political theory.  Also, see literature reviews in March 2013, Vallier 2014, and Bailey and Gentile 2014. While many public reason liberals have moved away from a restraint-based approach to religion in public life (Gaus and Vallier 2009, Laborde 2017, newer work defends such principles (Watson and Hartley 2018). Some even focus public reason on discourse, setting public justification aside (Leland 2019). Still other theorists have focused on developing principles of restraint appropriate for managing partisanship and the conduct of political parties (Bonotti 2017).
