ABSTRACT
As we have seen in earlier chapters one possible inference to draw from the fme-tuning data is that the constants of physics and the initial conditions at the Big Bang were fIxed by God who wished to create an anthropically fruitful universe. A counter strategy often adopted by those who wish to deny design is to postulate the existence of a multiverse, i.e. an ensemble of infInitely many universes, in which the constants and/or the initial conditions take on all possible values. We should then not be surprised to fmd ourselves in a universe with the parameters ours has, since we could not fmd ourselves in, and hence observe, any universe whose parameters differed by more than the smallest amount from ours. The kind of opponent of design I am describing usually wishes to adopt the position that all physical events can be explained solely, and exdusively, in terms of other physical events, a position I have dubbed 'scientifIc naturalism' .
