Abstract

In his Sermons, Joseph Butler argued for a series of extraordinarily subtle and perceptive claims about the relations between virtue and self-interest. Unfortunately, there has been a great deal of controversy among Butler's interpreters about what exactly these claims amount to, and about what role these claims play in the overall project of his Sermons. Commentators generally agree that the first method is the rationalist method, which Butler almost certainly associated with the work of Samuel Clarke and William Wollaston. The characteristic feature of this rationalist method is that it seeks to discover necessary truths by means of a priori reflection. By contrast, the second method starts out from contingent facts that are known on the basis of empirical observation. So Butler is claiming that the arguments of his Sermons are largely based on the contingent facts of empirical observation. One good way to understand what Butler means is to look at the earlier works of moral philosophy that are clearly influencing him.
