Abstract A number of years ago we argued that Hartshorne’s psychicalism and his doctrine of divine memory are incompatible with contemporary big bang cosmology. Theodore Walker has responded to our objection by arguing that our understanding of psychicalism is flawed and that Hartshorne’s metaphysics has the resources for accommodating what the big bang theory say about the origin and fate of the universe. In the present article we attempt to show that Walker’s defense of Hartshorne fails.
