The two books make a notable contribution in drawing together many of the philosophical problems about time, and the associated literature. The expositions are also valuable for their interdisciplinary strengths, especially in the history and philosophy of science and (to a lesser extent) in theology, and for the clarity and thoroughness of Craig's approach. However, the two books do not present, as might at first appear, a side by side exposition of the respective strengths and weaknesses of the A-series and the B-series views of time. They are, rather, one interconnected defence of the A-series view. Some of the strengths and weaknesses of Craig's exposition and defence of the A-series view are noted.
