All knowledge is partial, infinitesimally partial. Reason is a net thrown out into an ocean. What truth it brings in is a fragment, a glimpse, a scintillation of the whole truth.
Ursula K. Le GuinWhat the brain does by itself is infinitely more fascinating and complex than any response it can make to chemical stimulation.
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 GuinA man would know the end he goes to, but he cannot know it if he does not turn, and return to his beginning, and hold that beginning in his being. If he would not be a stick whirled and whelmed in the stream, he must be the stream itself, all of it, from its spring to its sinking in the sea.
