This paper begins by surveying some of the problems facing Swinburne's general approach, finding unfortunate the absence from his tetralogy of a strategy (suggested at the end of the previous trilogy) that might have helped to alleviate them, namely an attempt to show that a traditional Christian creed is more probable than the creed of any other religion. It then discusses certain particular arguments of the tetralogy – arguments offered in defence of the traditional Christian doctrine of the Atonement – which are central to the detailed working out of the approach, concluding that they are unacceptable.
