 First, recall from  Section 1.1  the difficulties of identifying a plausible and uncontroversial account of what the ethical supervenes on. Nicolas Sturgeon suggests that one conclusion to draw from these difficulties is that there is no dialectically significant ethical supervenience thesis. For example, he accepts the supervenience of the ethical on the natural, but he suggests that his reasons for accepting it are just his reasons for accepting ethical naturalism (2009, 61). He argues that philosophers who reject naturalism are likewise in a position to reject the supervenience of the ethical on the natural (2009, 62–7).
