We live well in the houses — well enough. But we are ruled utterly by fear. There was a time we sailed in ships between the stars, and now we dare not go a hundred miles from home. We keep a little knowledge, and do nothing with it. But once we used that knowledge to weave the pattern of life like a tapestry across night and chaos. We enlarged the chances of life. We did man’s work.
Ursula K. Le Guin, City of Illusions (1967)
