My one and only piece of relevant evidence [for an Aristotelian God] is the apparent impossibility of providing a naturalistic theory of the origin from DNA of the first reproducing species ... [In fact] the only reason which I have for beginning to think of believing in a First Cause god is the impossibility of providing a naturalistic account of the origin of the first reproducing organisms.
Antony FlewIf it is to be established that there is a God, then we have to have good grounds for believing that this is indeed so. Until and unless some such grounds are produced we have literally no reason at all for believing; and in that situation the only reasonable posture must be that of either the negative atheist or the agnostic. So the onus of proof has to rest on the proposition of theism.
Antony FlewThe Koran calls for belief and consequent obedience. It is, surely, calculated to inspire fear, indeed abject terror, rather than love.
Antony FlewHowever far back we may be able to trace the - so to speak - internal history of the Universe, there can be no question of arguing that this or that external origin is either probable or improbable. We do not have, and we necessarily could not have, experience of other Universes to tell us that Universes, or Universes with these particular features, are the work of Gods, or of Gods of this or that particular sort.
Antony FlewIn the ordinary, everyday understandings of the words involved, to say that someone survived death is to contradict yourself; while to assert that all of us live forever is to assert a manifest falsehood, the flat contrary of a universally known truth: namely, the truth that all human beings are mortal. For when, after some disaster, the 'dead' and the 'survivors' have both been listed, what logical space remains for a third category?
Antony FlewI am open to [the notion of theistic revelation], but not enthusiastic about potential revelation from God. On the positive side, for example, I am very much impressed with physicist Gerald Schroeder's comments on Genesis 1. That this biblical account might be scientifically accurate raises the possibility that it is revelation.
