Excerpt form his conversion story article:
But religion, once the glow of conversion had worn off, was not a matter of argument alone. It involves the whole person. Therefore I was drawn, over and over again, to the disconcerting recognition that so very many of the people I had most admired and loved, either in life or in books, had been believers. Reading Louis Fischer’s Life of Mahatma Gandhi, and following it up with Gandhi’s own autobiography, The Story of My Experiments With Truth, I found it impossible not to realise that all life, all being, derives from God, as Gandhi gave his life to demonstrate. Of course, there are arguments that might make you doubt the love of God. But a life like Gandhi’s, which was focused on God so deeply, reminded me of all the human qualities that have to be denied if you embrace the bleak, muddled creed of a materialist atheist. It is a bit like trying to assert that music is an aberration, and that although Bach and Beethoven are very impressive, one is better off without a musical sense. Attractive and amusing as David Hume was, did he confront the complexities of human existence as deeply as his contemporary Samuel Johnson, and did I really find him as interesting?
Watching a whole cluster of friends, and my own mother, die over quite a short space of time convinced me that purely materialist “explanations” for our mysterious human existence simply won’t do – on an intellectual level. The phenomenon of language alone should give us pause. A materialist Darwinian was having dinner with me a few years ago and we laughingly alluded to how, as years go by, one forgets names. Eager, as committed Darwinians often are, to testify on any occasion, my friend asserted: “It is because when we were simply anthropoid apes, there was no need to distinguish between one another by giving names.”
This credal confession struck me as just as superstitious as believing in the historicity of Noah’s Ark. More so, really.
I haven’t mentioned morality, but one thing that finally put the tin hat on any aspirations to be an unbeliever was writing a book about the Wagner family and Nazi Germany, and realising how utterly incoherent were Hitler’s neo-Darwinian ravings, and how potent was the opposition, much of it from Christians; paid for, not with clear intellectual victory, but in blood. Read Pastor Bonhoeffer’s book Ethics, and ask yourself what sort of mad world is created by those who think that ethics are a purely human construct. Think of Bonhoeffer’s serenity before he was hanged, even though he was in love and had everything to look forward to.
My departure from the Faith was like a conversion on the road to Damascus. My return was slow, hesitant, doubting. So it will always be; but I know I shall never make the same mistake again. Gilbert Ryle, with donnish absurdity, called God “a category mistake”. Yet the real category mistake made by atheists is not about God, but about human beings...
