 It has been objected that both versions of the cosmological argument set out an inflated picture of what explanations are reasonable. Why should the cosmos as a whole need an explanation? If everything in the cosmos can be explained, albeit through infinite, regressive accounts, what is left to explain? One may reply either by denying that infinite regresses actually do satisfactorily explain, or by charging that the failure to seek an explanation for the whole is arbitrary. The question, “Why is there a cosmos?” seems a perfectly intelligible one. If there are accounts for things in the cosmos, why not for the whole? The argument is not built on the fallacy of treating every whole as having all the properties of its parts. But if everything in the cosmos is contingent, it seems just as reasonable to believe that the whole cosmos is contingent as it is to believe that if everything in the cosmos were invisible, the cosmos as a whole would be invisible.
