Does moral non-naturalism have a problem with supervenience? That is, are necessary relations between moral and natural properties mysterious if those properties are distinct? Here I try to remove anxiety about the modal comments of moral non-naturalism. I also want to understand the source of the anxiety for those afflicted by it. That source is a commitment to what is called ‘Hume’s Principle’. I attack that principle.

野蛮非自然主义与休谟原则

道德非自然主义是否存在随附性问题？也就是说，如果道德属性和自然属性不同，它们之间的必然关系是否神秘？在这里，我试图消除对道德非自然主义模态评论的焦虑。我也想了解那些受它折磨的人焦虑的根源。该来源是对所谓的“休谟原理”的承诺。我攻击这个原则。
