). Reputedly he liked dancing and attending the clubs in London and New York. He was also obsessed with sport: he had played rugby for Eton, and was a noted cricketer and a keen supporter of the Tottenham Hotspur football team. For an academic, Ayer was an unusually well-connected figure in his time, with close links to 'high-society' and the establishment. Presiding over Oxford high-tables, he is often described as charming, but at times he could also be intimidating.

In Language, Truth and Logic (1936), Ayer rejected atheism

, as he understood it, on the grounds that any religious discourse was meaningless. He believed that religious language was unverifiable and as such literally nonsense. Consequently "There is no God" was for Ayer as meaningless and metaphysical an utterance as "God exists." Though Ayer could not give assent to the declaration "There is no God," he was an atheist in the sense that he withheld assent from affirmations of God's existence. However, in "Language, Truth and Logic" he distinguishes himself from both agnostics and atheists by saying that both these stances take the statement "God exists" as a meaningful hypothesis, which Ayer himself does not. He also criticises C A Mace's opinion that metaphysics is a form of intellectual poetry. The stance of a person who believes "God" denotes no verifiable hypothesis is sometimes referred to as igtheism

. When Ayer demanded that Tyson stop, the boxer said: "Do you know who the fuck I am? I'm the heavyweight champion of the world," to which Ayer replied: "And I am the former Wykeham Professor of Logic. We are both pre-eminent in our field. I suggest that we talk about this like rational men". Ayer and Tyson then began to talk, while Naomi Campbell slipped out.

Near-death experience

In 1988, shortly before his death, Ayer wrote an article entitled, "What I saw when I was dead", describing an unusual near-death experience. Of the experience, Ayer first said that it "slightly weakened my conviction that my genuine death ... will be the end of me, though I continue to hope that it will be." However, a few days later he revised this, saying "what I should have said is that my experiences have weakened, not my belief that there is no life after death, but my inflexible attitude towards that belief".

In 2001 Dr. Jeremy George, the attending physician, claimed that Ayer had confided to him: "I saw a Divine Being. I'm afraid I'm going to have to revise all my books and opinions." Ayer's son Nick, however, said that he had never mentioned this to him though he did find his father's words to be extraordinary, and said he had long felt there was something possibly suspect about his father's version of his near death experience.

Works

Ayer is best known for popularising the verification principle, in particular through his presentation of it in Language, Truth, and Logic

In the preface to the book, he defends his selection to hold the lectureship on the basis that Lord Gifford allowed wished to promote '“Natural Theology”, in the widest sense of that term', and that non-believers are allowed to give the lectures if they are “able reverent men, true thinkers, sincere lovers of and earnest inquirers after truth”.
