Is a non-natural fact, a fact that can’t be discovered by empiricism, or a fact that can’t be discovered by empiricism+logic? It could plausibly be the latter, since does use logical reasonjng, and there are examples of of quasi-logical. ethical systems, such as Kantianism and contractarianism, as well as quasi empirical ones like Platonism and Ethical intuitionism.
The frosting is the only thing the non-natural normative realist cares about.
If there are moral facts, whether natural or not, everyone should care about them. If they are accessible by abstract reasoning, then arguments from the causal closure of the physical don’t apply.
