Jared Oliphint and Nathan Shannon discuss Brian Leftow's God and Necessity (Oxford University Press). In this volume, Leftow seeks to offer a metaphysic of modality. This leads him into a discussion of necessity and possibility, truth making, God's nature, and divine simplicity. It's a wide-ranging title, but one that offers many important themes for consideration. Dr. Shannon has written a review of the book that will appear soon in the Westminster Theological Journal.
