Since he was very young he had known that in certain ways he was unlike anyone else he knew. For a child the consciousness of such difference is very painful, since, having done nothing yet and being incapable of doing anything, he cannot justify it. The reliable and affectionate presence of adults who are also, in their own way, different, is the only reassurance such a child can have; and Shevek had not had it.

— Ursula K. Le Guin, The Dispossessed, Harper & Row, Ch. 4, 1974
