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Do not quote yourself.
Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
No more than 5 quotes per person per monthly thread, please.
The problem isn't just that there are so many things we do for reasons too deep for us to understand; it is that our attempts to explain them spoil the party and cause us to stop doing them.
