Antony Flew
Notes
Antony Flew (1923–2010), British analytic philosopher and, for most of his career, the best-known academic defender of atheism in the English-speaking world. His 1950 paper "Theology and Falsification" argued that god-claims which no possible evidence could count against are not assertions at all, a point this vault makes under Popper's Razor and Ignosticism; The Presumption of Atheism (1976) argued that the Burden of Proof lies with the theist and that "atheism" should mean the absence of belief rather than a positive denial, which is the usage adopted under Atheism and Agnosticism. He named the No True Scotsman fallacy in Thinking About Thinking (1975). In 2004 he announced that he had come to accept a deistic god on the strength of arguments from the complexity of DNA and the origin of life; the 2007 book There Is a God, written with Roy Abraham Varghese, is widely held to reflect its co-author more than Flew, who by then was elderly and, by his own account, no longer followed the literature. He never accepted revelation, an afterlife or a personal god, so apologists who cite him as a convert overstate the case; see Argument from the Origin of Life and Argument from Specified Complexity.
