 This entry began with the suggestion that it is plausible that the ethical supervenes. This section has aimed to clarify some of our options for understanding that idea. The various interpretive options we have explored together suggest a dizzying space of possible ethical supervenience theses. This in turn raises a pressing question: which of these theses (if any) best articulate the plausibility and significance that philosophers have often taken ethical supervenience to have? One thing that might help to answer this question is to consider the arguments that we can give for supervenience: these arguments might favor some of these theses over others.
