The aim of this paper is to take a close look at some little discussed aspects of the kalam cosmological argument, with a view to deciding whether there is any reason to believe the causal principle on which it rests (“Whatever begins to exist must have a cause”), and also with a view to determining what conclusions can be drawn about the nature of the First Cause of the universe (supposing thatthere is one). I am particularly concerned with the problems (...) that arise when it is assumed (as it often is) that that the First Cause is timeless and that it timelessly creates time. I argue that this forces the defender of the kalam argument to analyze the concept of “beginning to exist” in a way that raises series doubts about its main causal principle, and that it also undercuts the main argument for saying that the cause of the universe must be a person.
