Nor could she frame deeper words herself; human understandings trickled shallow these days. It was the way. - Brian Aldiss

One of the objections I have against Campbell's Astounding was that there was too little love in it. It was a very loveless magazine. They never took enough account of the feeling that is always in SF.

It occurred to him that perhaps all his life he had only been hearing echoes of himself, and that his morality, on which he had once prided himself, was merely a refusal to permit other people into his life.

That first novel of mine, Non-Stop, is directly attributable to Heinlein. His "Common Sense" seemed to me such a good story, but bereft of any human feelings. I thought long about that story, and then I thought how wonderful it would be to write about a spaceship in which people have been imprisoned for generations and to put in something of the human feeling. So that novel is directly attributable to Heinlein. I thought, in my youthful arrogance, that I could do it better — I didn't! I thought I could do it differently, and I think I did do it differently. And I suppose that on the whole, I've concentrated on doing things differently ever since.
