This is a reply to a paper by Graham Oppy in the July, 1999 issue of this journal, “Koons’ Cosmological Argument.” Recent work in defeasible or nonmonotonic logic means that the cosmological argument can be cast in such a way that it does not presuppose that every contingent situation, without exception, has a cause. Instead, the burden of proof is shifted to the skeptic, who must produce positive reasons for thinking that the cosmos is an exception to the defeasible law of causality. I show how Oppy’s critique can be turned into a plausible rebuttal of my argument. However, this rebuttal can be set aside when the original argument is supplemented by a plausible account of the nature of causal priority. Several independent lines of argument in support of this account are outlined.

Does the cosmological argument (CA) depend on the ontological (OA)? That depends. If the OA is an argument “from mere concepts,” then no; if the OA is an argument from possibility, then yes. That is my main thesis. Along the way, I explore a number of subsidiary themes, among them, the nature of proof in metaphysics, and what Kant calls the “mystery of absolute necessity.”.

Abstract In his book Metaphysics, Peter van Inwagen constructs a version of the Cosmological Argument which does not depend on the Principle of Sufficient Reason. He goes on to reject the argument. In this paper, I construct an alternative version of the Cosmological Argument that uses some of van Inwagen's insights and yet is immune to his criticisms. If we suppose that for each contingent truth, there is some at least partial explanation, then it follows that there is some necessary truth that explains the conjunction of all the contingent truths.

This paper begins with a fairly careful and detailed discussion of the conditions under which someone who presents an argument ought to be prepared to concede that the argument is unsuccessful. The conclusions reached in this discussion are then applied to William Lane Craig’s defense of what he calls “the kalam cosmological argument.” Perhaps unsurprisingly, the chief contention of the paper is that Craig ought to be prepared to concede that “the kalam cosmological argument” is not a successful argument. The paper pays particular attention to Craig’s recent criticisms of Adolf Grünbaum’s contention that “the kalam cosmological argument” presupposes “the normalcy of nothingness”; and it also addresses some methodological issues raised by Craig’s response to my previous criticisms of his replies to critiques of “the kalam cosmological argument” provided by Grünbaum, Hawking, and Davies.

We present a valid deductive cosmological argument for the necessary existence of a powerful and intelligent creator of the actual universe. Whereas traditional cosmological arguments had to employ a strong version of the principle of sufficient reason that held that every fact actually has an explanation, our argument can make do with the weak version of Duns Scotus according to which every fact possibly has an explanation. As a result, our argument is less vulnerable to the charge of begging the question than are these traditional cosmological arguments.

Examples involving infinite suspended chains or infinite trains are sometimes used to defend perceived weaknesses in traditional cosmological arguments. In this article, we distinguish two versions of the cosmological argument, suggest that such examples can only be relevant if it is one specific type of cosmological argument that is being considered, and then criticize the use of such examples in this particular type of cosmological argument. Our criticism revolves around a discussion of what it means to call a system closed, and what it means to call an explanation complete. Our analysis makes no suppositions about the nature of the infinite, and is therefore independent of many of the issues around which contemporary discussions of the cosmological argument have tended to revolve.

The design argument is one of three main arguments for the existence of God; the others are the ontological argument and the cosmological argument. Unlike the ontological argument, the design argument and the cosmological argument are a posteriori. And whereas the cosmological argument can focus on any present event to get the ball rolling (arguing that it must trace back to a first cause, namely God), design theorists are usually more selective.

There is an intriguing recent effort to develop a valid cosmological argument on the basis of quite minimal assumptions.1 Indeed, the basis of the new cosmological argument is so slight that it is likely to make even a conscientious theist suspicious – to say nothing of our vigilant atheists. In Section 1 we present the background assumptions and central premises of the new cosmological argument. We are sympathetic to the conclusion that there necessarily exists an intelligent and powerful creator of the actual universe, but we show in Section 2 that the new cosmological argument cannot establish this claim. Specifically, we show by reductio ad absurdum that the new argument is unsound, and that every plausibly modified version of the argument is also unsound.2 We close our discussion with a diagnosis of what went wrong in the new cosmological argument. Our conclusion is that this intriguing new argument promises considerably more than it can show.
