Abstract

This chapter investigates the rationality of failing to believe miracle reports. Hume famously argued that it is irrational to believe that a miracle has occurred on the basis of testimony alone. While certain aspects of Hume's argument have received extensive discussion, other features of his argument have been largely overlooked. After offering a reconstruction of Hume's argument, I argue that epistemic defeat plays a central role in the argument, and I explore the aptness of as well as some limitations to Hume's reasoning. I then discuss the relevance of the prior likelihood of an event when evaluating the evidential strength that testimony to such an event provides. Finally, I explore some ways the argument is altered if we adopt a non-traditional picture of evidence and defeat.
