One of the things Gary Habermas asked Antony Flew about in their interview was what certain 20th century philosophers would have thought if they were still alive and had they seen modern apologetic advances and Flew’s apparent acceptance of belief in God.
One of these philosophers was A. J. Ayer, who was one of the architects of logical positivism (which was so anti-religious that it claimed religious statements literally had no meaning at all) in the 1950s (before it was pointed out that judged by their own criteria, central positivist claims also appeared to be meaningless, contributing to the movement’s collapse).
Ayer was venomously anti-religious, but before he died, he had a very unusual experience: In fact, he had a near-death experience. He choked on a piece of fish and was clinically dead for four minutes. When he came back, he reported his experience.
I’m not overly impressed with apologetic evidence allegedly offered by NDEs. In fact, I’m quite skeptical of them at this point.
Some of the press accounts of Ayer’s experience sound really weird and implausible–more like a hallucination than a genuine experience of the afterlife (though the Church acknowledges that the consciousness of a subject can mix elements into a genuine experience of the supernatural in private revelation).
Still, it’s a cosmic irony that Ayer–so long a proponent of the idea that talk about the afterlife was either meaningless or foolish–would have an NDE, following which he reported seeing the Supreme Being and saying that the event "weakened my conviction that death would be the end of me, though I continue to hope it will be."
His NDE made quite a splash in the press, both legitimate and illegitimate. After his experience was reported in an American tabloid (The Weekly World News, if I recall correctly), one of the professors in my philosophy department taped the story to his door and another (or possibly the same) professor wrote "Well, that’s it for empiricism" in the margin.
