In Whitehead's Radically Temporalist Metaphysics: Recovering the Seriousness of Time, George Allan argues that Whitehead's introduction of God into his process metaphysics renders his metaphysics incoherent. This notion of God, who is the reason for both stability and progressive change in the world and who is both the infinite source of novel possibilities and the everlasting repository for the finite values, inserts into a reality that is supposedly composed solely of finite entities an entity both infinite and everlasting. By eliminating this notion of God, Allan draws on the temporalist foundation of Whitehead's views to recover a metaphysics that takes time seriously. By turning to Whitehead's later writings, Allan shows how this interpretation is developed into an expanded version of the radically temporalist hypothesis, emphasizing the power of finite entities, individually and collectively, to create, sustain, and enhance the dynamic world of which we are a creative part.
