“I have a covenant with God. I cannot ask for anything outside what is written in the covenant. What I will achieve in this world is in a book I am carrying everyday; I just have to open the pages. Outside the book is not mine.”

Response to a would be biographer in 1980, as quoted in "When Stephen met Sylvia" in The Guardian (24 April 2004) http://books.guardian.co.uk/review/story/0,12084,1201328,00.html
Context: I am very honoured by your wanting to write a life of me. But the fact is I regard my life as rather a failure in the only thing in which I wanted it to succeed. I have not written the books I ought to have written and I have written a lot of books I should not have written. My life as lived by me has been interesting to me but to write truthfully about it would probably cause much pain to people close to me — and I always feel that the feelings of the living are more important than the monuments of the dead.

but how you do it, how you approach it, and what you come to value.
[…] There are many realities. We should remember this when we get too caught in being concerned about the way the rest of the world lives or how we think they live.

But I have talked about this and written about it and then, unfortunately, in a few occasions I was not as accurate as I have been in the past.

Context: Reason, when it is refined into logic, has something to offer but only in terms of itself and depends for its effect and use on the nature of the premise. That useful argument as to how many angels can stand on the point of a needle would turn into nothing without the concept of angels. I took a further step into my new world. I formulated what I had felt against a mass of reasonable evidence and saw that to explain the near infinite mysteries of life by scholastic Darwinism, by the doctrine of natural selection, was like looking at a sunset and saying "Someone has struck a match". As for Freud, the reductionism of his system made me remember the refrain out of Marianna in Moated Grande — "He cometh not, she said, she said I am aweary aweary, O God that I were dead!". This was my mind, not his, and I had a right to it....
We question free will, doubt it, dismiss it, experience it. We declare our own triviality on a small speck of dirt circling a small star at the rim of one countless galaxies and ignore the heroic insolence of the declaration. We have diminished the world of God and man in a universe ablaze with all the glories that contradict that diminution.
Of man and God. We have come to it, have we not? I believe in God; and you may think to yourselves — here is a man who has left a procession and gone off by himself only to end with another gasfilled image he towns round with him at the end of the rope. You would be right of course. I suffer those varying levels or intensities of belief which are, it seems, the human condition. Despite the letters I still get from people who believe me to be still alive and who are deceived by the air of confident authority that seems to stand behind that first book, Lord of the Flies, nevertheless like everyone else I have had to rely on memories of moments, bet on what once seemed a certainty but may now be an outsider, remember in faith what I cannot recreate.
