This sub-section has focused on morality. But there are other topics which arguably involve matters of value, such as aesthetics, the normativity of theoretical and practical reason, and so on. The constraints placed on theories of moral facts by naturalist considerations will apply, mutatis mutandis, in these areas too, militating against theories that posit non-natural value-bearing facts and in favour of naturalist alternatives, of either a realist or irrealist stripe.
