n the past I have written as though my opinions were set in concrete, apologetics, arguing for a particular Christian position. The further on I went, the less certainty I had and the more I began to prize uncertainty, without falling into absolute scepticism, which I think is paralysing. We have to hold all our beliefs with a kind of provisionality, because history teaches that we may have to drop them. We believed in slavery; we believed in the subordination of women; we believed that gays should be beyond decent society. I call it existential jazz – living in a way that enables you to listen to new things and develop a new ethic..... One of the things I’ve noticed is the drift to the right as you get older and I daresay that is probably happening to me. However, if you’re a writer, your attitudes tend not to harden quite so firmly, because you are constantly examining and questioning things. I am more accepting now about living with uncertainty. I just don’t want to be too certain of my uncertainty. .....

.... I’m having a great old age and I’m writing better than I ever did. My writing is more considered now. I always rushed things before. I never used to call myself a writer, but I do now and I get a tremendous kick out of it. And I will go on doing it until I pop. It’s a privilege to have something you don’t ever have to retire from. Writing is a good way to grow old.
