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Do not quote yourself.
Do not quote comments/posts on LW/OB.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.
This reminds me of the phrase "nobody learns faster than someone who is being shot at". Considering all the technological research done in war time, there seems to be a good point about motivation.
