This is a monthly thread for posting any interesting rationality-related quotes you've seen on LW/OB.

• 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• Do not quote yourself.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 post quotes that are NOT comments/posts on LW/OB - there is a separate thread for this.
• No more than 5 quotes per person per thread, please.

I always see that the monthly Rationality Quotes thread has this line: "Do not quote comments/posts on LW/OB - if we do this, there should be a separate thread for it." This is the thread for those quotes.
