Rationality Quotes: October 2009

A monthly thread for posting rationality-related quotes you’ve seen recently (or had stored in your quotesfile for ages).

  • Please post all quotes separately, so that they can be voted up/​down separately. (If they are strongly related, reply to your own comments. If strongly ordered, then fine, post them together.)

  • Do not quote yourself.

  • Do not quote comments/​posts on LW/​OB.

  • No more than 5 quotes per person per monthly thread, please.
