Ged had neither lost nor won but, naming the shadow of his death with his own name, had made himself whole: a man: who, knowing his whole true self, cannot be used or possessed by any power other than himself, and whose life therefore is lived for life's sake and never in the service of ruin, or pain, or hatred, or the dark.

Solitude is noncommunication, the absence of others, the presence of a self sufficient to itself.

Science 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.
