Rationality Quotes September–December 2016

Another month, another rationality quotes thread. The rules are:

  • Provide sufficient information (URL, title, date, page number, etc.) to enable a reader to find the place where you read the quote, or its original source if available. Do not quote with only a name.

  • 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  • Do not quote yourself.

  • Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson.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.

EDIT: I haven’t posted a monthly thread for October and November, since people haven’t been posting many quotes and some people have said a monthly frequency might be too high. I’ll make them quarterly instead. I should actually have made a new thread for October-December, but I’ll leave it like this since people have been posting in it this month.
