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- Do not quote yourself.
- Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson.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.
And one new rule:
- 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 Do not quote with only a name.
-- Rational!Quirrel, HPMoR chapter 20
In other words: how else can you justify a moral belief and consequent actions, except by saying that you really truly believe in your heart that you're Right?
We should not confuse between the fact that almost all people other than Manson think he was morally wrong, and the fact that his justification for his action seems to me to be of the same kind as the justifications anyone else ever gives for their moral beliefs and actions.
Unlike Quirrell, Penn Jillette is not referring to "knowing in your heart" that your moral values are correct, but to "knowing in your heart" some matters of fact (which may then serve as a justification for having some moral values, or directly for some action).
