 Relatively little has so far been written on the topic of tropes in relation to issues in moral philosophy and value theory. Two things have however been argued. First, that tropes (and not, as is more commonly supposed, objects or persons or states of affairs) are the bearers of final value. Second, that moral non-naturalists (who hold that moral facts are fundamentally autonomous from natural facts) must regard properties as tropes to be able to account for the supervenience of the moral on the natural.
