Although he retains his dislike of violence, he has lost his Quaker religious faith and calls himself an agnostic. In an interview published in the Times newspaper in 2000 Sanger is quoted as saying: "My father was a committed Quaker and I was brought up as a Quaker, and for them truth is very important. I drifted away from those beliefs – one is obviously looking for truth but one needs some evidence for it. Even if I wanted to believe in God I would find it very difficult. I would need to see proof".
