A monthly thread for posting rationality-related quotes you've seen recently (or had stored in your quotesfile for ages).
- Please post all quotes separately, so that they can be voted up/down 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- Do not quote yourself.
- Do not quote comments/posts on LW/OB.
- No more than 5 quotes per person per monthly thread, please.
That's not even empirically true. At best, morality is the (really complicated) function relating "is" and "ought" - which means errors in the "is" can make vast differences to the consequent "ought".
(For example, in the Americas a couple centuries ago, it was widely believed that black people were not capable of being successful and happy without supervision of white people, and it was consequently meet to own such people in the same way as livestock is owned.)
As much as I keep citing this as an example myself, I don't think we're literally talking about sole prior cause and posterior effect here.
