contrary to the traditional definition of justice as to-each-their-own. Some of Flew's later works, such as Politics of Procrustes and Equality in Liberty and Justice, were focused on this subject. While an undergraduate, Flew attended the weekly meetings of C. S. Lewis' Socratic Club fairly regularly. Although he found Lewis to be "an eminently reasonable man" and "by far the most powerful Christian apologists for the sixty or more years following his founding of that club", he was not persuaded by Lewis' argument from morality as found in Mere Christianity (1952). Flew also criticised several of the other philosophical arguments for God's existence. He concluded that the ontological argument in particular failed because it is based on the premise that the concept of Being can be derived from the concept of Goodness. Only the scientific forms of the teleological argument ultimately impressed Flew as decisive. During the time of his involvement in the Socratic Club, Flew also wrote the article Theology and Falsification, which argued that claims about the existence of a God were merely vacuous since they couldn't be falsified, therefore it was impossible to test these claims for truth or falsehood. Flew was also critical of the idea of life after death and the free will defence to the problem of evil. In 1998, he debated Christian apologist and philosopher William Lane Craig over the existence of God. Flew married on 28 June 1952. He had two daughters. Flew died on 8 April 2010, while nursed in an extended care facility in Reading, England, suffering from dementia. Atheism and Deism The Presumption of Atheism Antony Flew's most influential professional works was his 1976 The Presumption of Atheism in which Flew forwarded the proposition that the question of God's existence should begin with the presupposition of atheism until empirical evidence for the existence of a God surfaces. He also criticised the idea of life after death, the free will defence to the problem of evil, and the meaningfulness of the concept of God. Flew's proposal to change his profession's use of the term "atheism" saw limited acceptance in the 20th century, but in the early 21st century Flew's definition of the negative sense of atheism came to be forwarded more commonly by people who identify as atheists. According to Christian apologist and philosopher William Lane Craig's 2007 assessment regarding the impact of Flew's proposed concept of negative atheism, the
