Aumann agreement theorem

Why do you refer to science? Didn't you read Yudkowsky's anti-science rants? You are supposed to refer to Yudkowsky's interpretation of Bayes' theorem.

Also, you can't assume that utilitarianism is the "true" moral system, or the only possible framework to look at moral issues through. Hume's law can't be surpassed. No, not even by Yudkowsky. There is no correct moral theory. Certain utilitarian applications come across as rather horrible to the majority of us, so we choose not to apply them.
