Philosophers who wish to argue for the rationality of belief in God frequently employ a 'god-of-the-gaps' strategy. This strategy consists in trying to find a phenomenon that cannot be explained by natural science, and insisting that it can be explained only by reference to the activity of God. Philosophical discussion of miracles usually revolves around the attempt to link a miracle to God in just this way. One of the problems with this approach is that it is very difficult to identify anything as being forever beyond the power of science to explain. Science continues to advance upon the territory occupied by the god of the gaps. Thus it is desirable to develop an account of divine agency that will not be subject to revision in the face of scientific progress. This book is just such an account. Drawing on recent work in the theory of action, it shows that we can attribute God's agency to an event in nature without eliminating the possibility that it might be explained scientifically. In bringing God's actions out of the gaps, we avoid the possibility that future discoveries in science will make our talk of divine agency obsolete.
