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Do not quote yourself.
Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson.
No more than 5 quotes per person per monthly thread, please.
Of course, many works traditionally labeled fantasy also prefer to explore the consequences of worlds with different physics (HPMoR, for example). I've heard this called "Hard fantasy".
