Some philosophers think that if someone acts wrongly while falsely believing that her act is permissible, this moral mistake cannot excuse her wrongdoing. And some think that this is because it is morally blameworthy to fail to appreciate the moral significance of non‐moral facts of which one is aware, such that mistakenly believing that one's act is permissible when it is in fact wrong is itself morally blameworthy. Here I challenge the view that it is blameworthy to fail to appreciate (...) the moral significance of non‐moral facts of which one is aware. This view seems okay if we focus on examples of people mistakenly believing that their wrongful acts are permissible. But it is not remotely plausible when we consider other varieties of moral mistake – such as believing that one's action is required when it is in fact supererogatory, believing that one's action is wrong when it is in fact permissible, and believing false things about the moral properties of others’ actions and of merely possible actions. The upshot is that those who maintain that moral mistakes cannot excuse are sent back to the drawing board; we need a new explanation of why this would be the case. (shrink)

I develop and defend metaethical experientialism, the thesis that phenomenal facts explain certain kinds of value facts. I argue, for example, that anyone who knows what it’s like to feel extreme pain is in a position to know that that kind of experience is bad. I argue that metaethical experientialism yields genuine counterexamples to the principle that no ethical conclusion can be derived from purely descriptive premises. I also discuss the prospects for a pluralistic metaethics, whereby different metaethical theories hold (...) for different classes of ethical facts. (shrink)

While nudging has garnered plenty of interdisciplinary attention, the ethics of applying it to climate policy has been little discussed. However, not all ethical considerations surrounding nudging are straightforward to apply to climate nudges. In this article, we overview the state of the debate on the ethics of nudging and highlight themes that are either specific to or particularly important for climate nudges. These include: the justification of nudges that are not self-regarding; how to account for climate change denialists; transparency; (...) knowing the right or best behaviours; justice concerns; and whether the efficacy of nudges is sufficient for nudges to be justified as a response to the climate crisis. We conclude that climate nudges raise distinct ethical questions that ought to be considered in developing climate nudges. (shrink)
