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 go ahead and 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Do not quote yourself.
Do not quote comments/posts on LW/OB.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.
There's some equivocation here. "Ridiculous" can mean, as the etymology would suggest, "that which should be ridiculed", or it can mean "not sensible". In the latter case, the ridiculous should not necessarily be ridiculed.
