A monthly thread for posting any interesting rationality-related quotes you've seen recently on the Internet, or had stored in your quotesfile for ages.
Please post all quotes separately (so that they can be voted up/down separately) unless they are strongly related/ordered.
Do not quote yourself.
Do not quote comments/posts on LW/OB - there is a separate thread for it.
No more than 5 quotes per person per monthly thread, please.
