Antony Flew’s book, There is a God (2007), is a helpful resource for someone trying to decide whether there are good grounds for believing in God. It requires some interest in philosophical topics, but it isn’t too technical and the storyline carries the reader forward despite some difficult spots. Flew insists that his conversion to deism (after being an atheist for most of his professional career) was the outcome of following Socrates’ dictum, ‘follow the evidence wherever it leads.’
Flew begins the book by tracing his early childhood years and the experiences of evil that convinced him to embrace atheism during his adolescence. He then recounts all the ways he used to argue against the existence of God during his career as a respected philosopher: e.g. the presumption of atheism, the incoherence of theism, the failure of theistic proofs, problems with falsifying theism, etc.
According to There Is a God (2007), Flew’s thinking about God changed upon finding adequate responses to his atheistic arguments and weighing new evidence from science, cosmology, and contingency. The conclusion of the book is that deism (not atheism) the most likely position to be true compared to its alternatives. He still denies belief in any revealed religion (due to the problem of evil) but he seems particularly impressed with the historical testimony to the bodily resurrection of Jesus of Nazareth.
I’d recommend this book to any serious seeker of truth – whether a believer, skeptic, or agnostic – if only because it is refreshing to see an academic giant of Flew’s caliber change his mind at the risk of being dismissed by his colleagues.
