Cuneo and Shafer-Landau have argued that there are moral conceptual truths that are substantive and non-vacuous in content, what they called ‘moral fixed points’. If the moral proposition ‘torturing kids for fun is pro tanto wrong’ is such a conceptual truth, it is because the essence of ‘wrong’ necessarily satisfies and applies to the substantive content of ‘torturing kids for fun’. In critique, Killoren :165–173, 2016) has revisited the old skeptical ‘why be moral?’ question and argued that the moral fixed (...) points give us no reason to care about morality and, therefore, they are normatively irrelevant. He concluded that this is a counterintuitive implication that undermines the proposal. In this paper, I develop a rejoinder to Killoren’s argument that explains why, at least from the perspective of the moral fixed points framework, if the moral fixed points exist, they are necessarily normatively relevant for rational agents. I supplement this explanation with an explanation of why it might prima facie appear that moral fixed points are not normatively relevant, although ultima facie they are relevant. The supplementary explanation explains prima facie normative irrelevance as the upshot of failures of rational agency. I conclude that the moral fixed points, can, in principle, offer an interesting response to the skeptical ‘why be moral?’ question’. (shrink)

Ingram (2015) has argued that Cuneo and Shafer-Landau’s (2014) ‘moral fixed points’ theory entails that error theorists are conceptually deficient with moral concepts. They are conceptually deficient with moral concepts because they do not grasp moral fixed points (e.g. ‘Torture for fun is pro tanto wrong’). Ingram (2015) concluded that moral fixed points theory cannot substantiate the conceptual deficiency charge and, therefore, the theory is defeated. In defense of moral fixed points theory, Kyriacou (2017a) argued that the theory is coherent (...) with the error theorists being conceptually competent with moral concepts, while reflectively denying moral fixed points theory. This is because error theorists could be conceptually competent with moral concepts but, due to intellectual vices, be swayed by unsound arguments against moral fixed points theory. Ingram (2018) replied to Kyriacou (2017a) that the intellectual vice charge against error theorists cannot be substantiated and, therefore, the moral fixed points theory is still defeated. In this paper, I argue that the possibility of intellectual vice is independently plausible and sufficient to undermine Ingram’s argument against the moral fixed points theory. (shrink)
