The most reasonable belief is that we came from nothing, by nothing, and for nothing. -Quentin Smith, Theism, Atheism, and Big Bang Cosmology, 135.
Is this so reasonable? Is it true that we came from nothing, by nothing, and for nothing? The Kalam Cosmological Argument is one of the most compelling arguments for theism. The broad opposition to the Kalam (or, more specifically, to its implications) from atheists has lead to some sophisticated arguments (like those of Graham Oppy or J.L Mackie), but it has also lead to some pretty poor arguments. Below, several objections to the Kalam Cosmological Argument have been outlined, along with rebuttals of varying lengths.
Some have objected to the Kalam by raising the possibility of a multiverse. They say that this counters the Kalam because it’s possible that our universe is one of nearly infinite past universes, generated as another “bubble” among untold trillions of other bubble universes. There should be one glaring difficulty with this objection that most can see immediately: “Whence the multiverse?” If the multiverse is proposed as eternal, then every objection about actual infinites applies to the multiverse. Not only that, but the multiverse itself would have to account for entropy. How is it that all the energy in this (nearly) infinite multiverse has not been used if it has existed for all eternity?
Ways around these difficulties have been proposed. For example, regarding entropy, some have argued that perhaps different laws of nature apply to the multiverse as a whole. Clearly, this is an extremely ad hoc theory that is really only invented to try to get around the argument. Once we’re allowed to modify reality to our every whim, we could indeed create anything we like–including (nearly) infinite universes. Continue reading
