William Lane Craig's defence of the kalam cosmological argument rests heavily on two philosophical arguments against a past-eternal universe. In this article I take issue with one of these arguments, what I call the – namely, that the metaphysical absurdity of an actually infinite number of things existing precludes the possibility of a beginningless past. After explaining this argument, I proceed to raise some initial doubts. After setting those aside, I show that the argument is ineffective against proponents of presentism. (...) The remainder of the article considers and rejects possible replies on Craig's behalf. (shrink)

A popular critique of the kalām cosmological argument is that one argument for its second premise illicitly assumes a finite starting point for the series of past temporal events, thereby begging the question against opponents. Rejecting this assumption, opponents say, eliminates any objections to the possibility that the past is infinitely old and undermines the IFA’s ability to support premise 2. I contend that the plausibility of this objection depends on ambiguities in extant formulations of the IFA and that we (...) may resolve these ambiguities in a way that does not presuppose a finite staring point. I also argue that this disambiguation allows us to construct an argument demonstrating that the concept of an infinite past entails a contradiction. (shrink)

Yishai Cohen raises three related objections to the kalam cosmological argument. Firstly, Cohen argues that, if the argument against the possibility of an actual infinite, which is used to support the kalam cosmological argument, is sound, then a predetermined endless future must also be impossible. Secondly, Cohen argues that the possibility of a predetermined endless future entails the possibility of an actual infinite. Finally, Cohen maintains that Robert C. Koons’ Grim Reaper paradox shows that a predetermined endless future is impossible. (...) I intend to show that Cohen’s three arguments are not sound and that the possibility of an endless future is not a thorn in the kalam cosmological argument. (shrink)
