The Meaning of Philo's Reversal

There are two ways of hearing Philo's unexpected endorsement of a version of the design hypothesis in the final part of Hume's Dialogues. We might register it in accordance with Cleanthes's descriptivist approach to religious speech, taking Philo to be reasoning with Cleanthes in Cleanthes's own way. Or we might hear Philo's words in accordance with his own expressivist account of religious speech, an account that Philo appears to have borrowed from Hobbes. I argue that Hume intended this double layering of meanings, presenting us with two distinct ways we might understand Philo's closing remarks. Each possible reading reveals a distinct Humean lesson about the limitations of natural theology.
