I think the attempt to defend belief can unsettle it, in fact, because there is always an inadequacy in argument about ultimate things.
I read things like theology, and I read about science, Scientific American and publications like that, because they stimulate again and again my sense of the almost arbitrary given-ness of experience, the fact that nothing can be taken for granted.
Fact explains nothing. On the contrary, it is fact that requires explanation.
I owe everything that I have done to the fact that I am very much at ease being alone.
I tend to think of the reading of any book as preparation for the next reading of it. There are always intervening books or facts or realizations that put a book in another light and make it different and richer the second or the third time.
