Sci-fi uses the images that sf - starting with H.G. Wells - made familiar: space travel, aliens, galactic wars and federations, time machines, et cetera, taking them literally, not caring if they are possible or even plausible. It has no interest in or relation to real science or technology. It's fantasy in space suits. Spectacle. Wizards with lasers. Kids with ray guns. I've written both, but I have to say I respect science fiction enough that I wince when people call it sci-fi.
Ursula K. Le GuinWe like to think we live in daylight, but half the world is always dark, and fantasy, like poetry, speaks the language of the night.
Ursula K. Le GuinA child free from the guilt of ownership and the burden of economic competition will grow up with the will to do what needs doing and the capacity for joy in doing it. It is useless work that darkens the heart. The delight of the nursing mother, of the scholar, of the successful hunter, of the good cook, of the skilful maker, of anyone doing needed work and doing it well, - this durable joy is perhaps the deepest source of human affection and of sociality as a whole.
Ursula K. Le GuinHardly anybody ever writes anything nice about introverts. Extroverts rule. This is rather odd when you realise that about nineteen writers out of twenty are introverts. We are been taught to be ashamed of not being 'outgoing'. But a writer's job is ingoing.
Ursula K. Le GuinA scientist can pretend that his work isn't himself, it's merely the impersonal truth. An artist can't hide behind the truth. He can't hide anywhere.
Ursula K. Le GuinIt win be a device that will permit communication without any time interval between two points in space. The device will not transmit messages, of course; simultaneity is identity. But to our perceptions, that simultaneity will function as a transmission, a sending. So we will be able to use it to talk between worlds, without the long waiting for the message to go and the reply to return that electromagnetic impulses require. It is really a very simple matter. Like a kind of telephone.
Ursula K. Le GuinFor we each of us deserve everything, every luxury that was ever piled in the tombs of the dead Kings, and we each of us deserve nothing, not a mouthful of bread in hunger. Have we not eaten while another starved? Will you punish us for that? Will you reward us for the virtue of starving while others ate? No man earns punishment, no man earns reward. Free your mind of the idea of deserving, the idea of earning, and you will begin to be able to think.
