In this paper, I develop an argument against a type of Non-Analytic Normative Naturalism. This argument, the Normative Property Dualism Argument, suggests that if Non-Analytic Normative Naturalists posit that normative properties are identical to natural properties and that such identities are a posteriori, they will be forced to posit that these properties that are both normative and natural have higher-order normative properties of their own.

规范属性二元论论证

在本文中，我提出了反对一种非分析规范自然主义的论点。这个论点，即规范属性二元论论证，表明如果非分析规范自然主义者假设规范属性与自然属性相同，并且这种身份是后验的，那么他们将被迫假设这些既是规范属性又是自然属性的属性它们自己的高阶规范属性。
