Another month has passed and here is a new rationality quotes thread. The usual rules are:
Please post all quotes separately, so that they can be upvoted or downvoted 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Do not quote yourself.
Do not quote from Less Wrong itself, Overcoming Bias, or HPMoR.
No more than 5 quotes per person per monthly thread, please.
Sometimes a downvote will lead to more overall upvotes than an upvote would have. Just like you can increase the probability of a sentence being quoted by including a typo, on purpose (try it!). Mind games!
