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. Now, we dare not go 100 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.
Ursula K. Le Guin
