 Section 1.3  showed that one of the crucial choice-points in theorizing ethical supervenience is the strength of the modality of the supervenience relation (conceptual? metaphysical? etc.). And  Section 3  and  Section 4  showed that the claim that the ethical supervenes with conceptual or metaphysical necessity is the starting point for several influential arguments. Gideon Rosen’s (2020) develops a view of the modal strength of ethical supervenience that is intended to be strong enough to accommodate the intuitive appearances, while weak enough to be dialectically inert.
