Graham Oppy has emerged as one of the kalam cosmological argument’s most formidable opponents. He rejects all four of the arguments drawn from metaphysics and physics for the second premiss that the universe began to exist. He also thinks that we have no good reason to accept the first premiss that everything that begins to exist has a cause. In this response, I hope to show that the kalam cosmological argument is, in fact, considerably stronger than Oppy claims, surviving even (...) his trenchant critique. (shrink)

I argue that there are Leibnizian-style cosmological arguments for the existence of God which start from very mild premises which affirm the mere possibility of a principle of sufficient reason. The utilization of such premises gives a great deal of plausibility to such types of argumentation. I spend the majority of the paper defending three major objections to such mild premises viz., a reductio argument from Peter van Inwagen and William Rowe, which proffers and defends the idea that a necessary (...) proposition cannot explain a contingent one. I, then, turn to an amelioration of the Rowe/van Inwagen argument which attempts to appeal to an entailment relation between explanans and explanandum that is fettered out in terms of relevance logic. Subsequent to dispelling with that worry, I tackle objections to the utilization of weak principles of sufficient reason that depend essentially upon agglomerative accounts of explanation. (shrink)
