Further to the controversy about the new book "by" philosopher Antony Flew (with "co-author" Roy Varghese), this lengthy analysis by Richard Carrier can be left (pretty much) to speak for itself.
Carrier was in the thick of things when Flew first publicly announced that he was becoming a deist, and had some initial success in talking the ageing philosopher out of it. He now argues, among other things, that Flew could not possibly have written a book in this form, or even signed off on it with any genuine understanding of its content, given the previous history of the whole affair. In particular, Carrier argues, Flew would surely have responded to issues that arose in their detailed correspondence over scientific arguments for deism. There are other indicators that Flew has had little to do with the book - it is, Carrier says, written in nothing like his usual style, and it gives no real indication of Flew's actual, publicly-expressed views about Christianity, which he still rejects (Flew rejects belief in a providential deity or an afterlife).
I'll just say that the claim that Flew is a genuine co-author of this book is currently looking even more incredible. Decide for yourself.
I don't mind this sort of thing so much when an ageing fiction writer lends his famous name to work written substantially or entirely by a younger, more energetic, "co-author", though there is of course an ethical issue involved even there. We all know it happens, unfortunately.
But when what is at stake is whether a renowned philosopher genuinely understands and endorses the arguments attributed to him, on an issue of enormous public interest, in a work aimed straight for best-sellerdom ... well, the implications are enormous if this volume is, in some sense, a fake. Ironically, and perhaps sadly, the controversy surrounding There Is a God will probably boost its sales. I suppose I need to read it myself.
