Art, like sex, cannot be carried on indefinitely solo; after all, they have the same enemy, sterility.
Ursula K. Le GuinScience fiction - and the correct shortcut is 'sf' - uses actual scientific facts or theories for the source ideas or framework of the story. It has some scientific content, however speculative. If it breaks a law of physics, it knows it's doing so and follows up the consequences. If it invents a society of aliens, it does so with some respect for and knowledge of the social sciences and what you might call social probabilities. And some of it is literarily self-aware enough to treat its metaphors as metaphors.
Ursula K. Le GuinIt's probably simply a matter of temperament that I never stopped to wonder if I could "match" what I had done, never choked off my writing by competing with myself, or with anybody else for that matter. My ambition was absolutely centered on the work itself, never on what it would bring me, or "who" it would make me. I never cared about that at all.
