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Do not quote yourself.
Do not quote comments/posts on LW/OB.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.
