Is it possible for God both to create a deterministic world and to act specially, to realize his particular purposes within it? And if there can be such ‘particular providence’ or ‘special divine action’ (SDA) in a deterministic world, what form can it take? In this article I consider these questions, exploring a number of different models of SDA and discussing their consistency with the proposition that the world is deterministic; I also consider how the various consequences of each model accord with traditional theistic assumptions about God's action in the world. I argue that, although SDA is possible in a deterministic world, none of the models that have been offered are entirely unproblematic, but accepting any of them commits one to certain consequences that may be found objectionable; thus the potential benefits of each model of SDA must be weighed against the costs of accepting such consequences.
