Abstract

Either 1. the non-naturalist is in a state of mind that would treat as relevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters, or 2. the non-naturalist is in a state of mind that would treat as irrelevant information about the existence and patterns of non-natural properties and facts as they make up their mind about normative matters. The first state of mind is morally objectionable, for one should not change one’s normative beliefs to pander to the patterns of some non-natural realm. The second state of mind is irrational, for if you think you are aiming to represent non-natural properties correctly, you should be interested to know which actions share a non-natural property and which do not, and you should be prepared to change your mind accordingly.
