David Bentley Hart on Misunderstanding the Cosmological Argument
It is immaterial whether one is wholly convinced by such reasoning. Even its most ardent proponents would have to acknowledge that it is an almost entirely negative deduction, obedient only to something like Sherlock Holmes’ maxim that “when you have eliminated the impossible, whatever remains, however improbable, must be the truth.” It certainly says nearly nothing about who or what God is.
But such reasoning is also certainly not subject to the objection from infinite regress. It is not logically requisite for anyone, on observing that contingent reality must depend on absolute reality, to say then what the absolute depends on or, on asserting the participation of finite beings in infinite being, further to explain what it is that makes being to be. Other arguments are called for, as Hume knew. And only a complete failure to grasp the most basic philosophical terms of the conversation could prompt this strange inversion of logic, by which the argument from infinite regress — traditionally and correctly regarded as the most powerful objection to pure materialism — is now treated as an irrefutable argument against belief in God.
