I had long ago discovered that when a word or formula refused to come to mind the best thing for it was to think of something else: tigers for instance or oatmeal. Then when the fugitive word was least expecting it I would suddenly turn the full blaze of my attention back onto it catching the culprit in the beam of my mental torch before it could sneak off again into the darkness.

I had thought for years, probably 30 or 40 years, that it would be a lot of fun to try my hand at a classic English mystery novel... I love that form very much because the reader is so familiar with all of the types of characters that are in there that they already identify with the book.

What intrigued me more than anything else was finding out the way in which everything, all of creation - all of it! - was held together by invisible chemical bonds, and I found a strange, inexplicable comfort in knowing that somewhere, even though we couldn't see it in our own world, there was a real stability.

Liberals have always been the most fervent Imperialists.

Except I'm aware that as a writer you can't get away with as much writing for children as you can with adults. Children have much more finely tuned senses of justice, morals, and ethics. They are much more Platonic: children are symmetrical, before we begin to fragment them with our own nonsensical ideas and squelch their natural joy in knowledge.

Whenever I'm with other people, part of me shrinks a little. Only when I am alone can I fully enjoy my own company.
