2. What explains the fine tuning of the universe?

Short answer: There’s no rigorous way to define fine tuning that’s hospitable to a fine tuning argument. Even if there were, a multiverse ensemble would be about as good an explanation as Theism.[ref] Another move atheist could make is to ‘trump’ fine tuning with an argument from evil. For even if it is the case that a fine tuned universe alone would support theism, it might be that further knowledge (it is fine tuned but has lots of evil in) will support atheism, in a similar way that knowing the accused was in the house at the time of the murder is some evidence for his guilt, but finding out he was locked in the basement is evidence for his innocence. (cf. Draper’s work on this). [/ref]

Long answer: The fine tuning or teleological argument has had a long and august history, and it has a new lease of life due to modern scientific discovery. For a variety of parameters (the gravitational constant, the cosmological constant, and so on) any slight deviation from their actual values would, as far as we can work out, lead to a universe where intelligent life is impossible. So surely this is a cosmological watch for want of a watchmaker? Continue reading “What explains the fine tuning of the Universe?”
