Here's the new thread for posting quotes, with the usual rules:
- 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- Do not quote yourself.
- Do not quote comments/posts on LW/OB.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.
While this quote isn't directly about rationality, it reminds me a good deal of Tsuyoku Naritai!.
~ Theodore Roosevelt, The Man in the Arena
(Edit: Just to clarify as some might misinterpret the posting of this to be a knock on rationality, the relevance of this quote is that what counts is trying to solve problem. While with hindsight it's easy to say how (to pick a mundane example) one might work out the area under a curve once you already know calculus, it's not so easy to do it without that knowledge.)
