One's life has value so long as one attributes value to the life of others, by means of love, friendship, indignation, and compassion.

- Simone de Beauvoir

"people can be naive, unsophisticated agents, can coordinate themselves to achieve complex, mutually beneficial ends even if the are not sure, at the start, what those ends are or what it will take to accomplish them. As individuals, they don't know where they are going. But as part of a market, they are suddenly able to get there, and fast."

James Surowiecki
