Abstract
William Lane Craig has defended a modern First Cause argument based on 1) a principle of universal causality and 2) the claim that the universe must have had a beginning. But 1) is susceptible to counter examples from quantum theory. Moreover, Craig’s defense of 2) is open to serious question. He claims that an actual infinity (of time) is impossible; he also claims that 2) is in fact supported by big bang theory. I argue that both of these claims are mistaken, and that in consequence we have no particular reason to suppose that 2) is true. I conclude that the First Cause argument fails, but I suggest that a weaker inductive argument might be worth a try.
