The naturalist who embraces the multiverse has a another problem in addition to the problem with miracles. Darwinian evolution is predicated on uniformitarianism, the belief that the laws of physics never change, but if there's a multiverse, of which we are a part, then uniformitarianism becomes highly improbable.
Torley writes:
[S]ince the argument for Darwinian evolution is based on the assumption that the laws and parameters of Nature do not vary, it follows that if we live in a multiverse, then our own universe is infinitely more likely to be one in which the miracles of the Bible occurred than a uniformitarian one in which life evolved in a Darwinian fashion.What a pickle. The naturalist rejects miracles and accepts Darwinian evolution (i.e. that evolution is a completely natural process with no intelligent input from a non-natural mind) largely because he rejects the existence of God.
... there will still be a number of possible universes in the multiverse, in which life pops into existence in the manner described in Genesis 1, and where living things just happen to exhibit the striking traits predicted by Darwinism, whereas there is (by definition) only ONE way for a given set of laws and parameters NOT to vary: namely, by remaining the same at every point in space and time.
The problem [for the naturalist] is that the uniformitarian requirement that the laws and parameters of Nature are the same at every point in space and time – which is rather like hitting bull’s eyes again and again and again, for billions of years – is inherently so very unlikely, when compared to “singularism” (the hypothesis that the laws of Nature undergo slight, short-lived or local fluctuations)...
Thus in a multiverse scenario, uniformitarianism becomes the albatross around the neck of Darwinism: no matter how many of Darwin’s predictions scientists manage to confirm, the sheer unlikelihood of the hypothesis that we live in a universe whose laws never vary renders Darwinism too unlikely a theory to warrant scientific consideration.
He buttresses that rejection by also accepting the idea of the multiverse as an answer to the argument for God's existence based on cosmic fine-tuning, but by accepting the multiverse he pretty much has to give up the underlying assumption of Darwinism (uniformitarianism) and also his opposition to miracles.
He seems to be mired in an intellectual quagmire, and it's not at all clear how he can extricate himself from it.
More on the naturalist's difficulties tomorrow.
