Artificial intelligence (AI) ethics is proposed as an emerging and interdisciplinary field concerned with addressing the ethical issues of AI, such as the issue of moral decision-making. The conflict between our intuitive moral judgments constitutes an inevitable obstacle to decision-making in AI ethics. This article outlines the Moral Relevance Approach, which could provide a considerable moral foundation for AI ethics. Taking moral relevance as the precondition of the consequentialist principles, the Moral Relevance Approach aims to plausibly consider individual moral claims. (...) It is not only the common ethical target shaping our moral consensus but also the inherent moral ability connecting others with us. (shrink)

Stephen Darwall’s moral theory explains moral obligation by appealing to a “second-person” standpoint where persons use second-person reasons to hold one another accountable for their moral behavior. However, Darwall claims obligations obtain if and only if hypothetical persons endorse them, despite tying the second-person standpoint to our real-world moral practices. Focus on hypothetical persons renders critical elements of his account obscure. I solve this problem by distinguishing two ideas quietly working in tandem, the hypothetical endorsement of moral norms and the (...) hypothetical recognition of these norms. Hypothetical endorsement is a plausible source of normativity; hypothetical recognition is not. A more plausible account of second-person normativity must combine hypothetical endorsement with actual recognition. I term these alternative conceptions justification and easy publication. To combine justification and easy publication in an account of moral obligation, second-person normativity should be applied first to rules. Following other moral philosophers, I introduce the concept of a “social-moral” rule into an account of moral obligation. Social-moral rules acquire normative force when they are justified for and easily published by the relevant moral community. I conclude that a rule-centric account of second-personality is superior to Darwall’s reason-centric account. (shrink)

Common-sense morality seems to tell us that a rescuer who can save either one individual or five other individuals from death has a duty to save the greater number. But contractualism, a moral theory on which principles must be justifiable to individuals, seems to imply that it is permissible to save the one. This is because a commitment to individual justification blocks the possibility of appealing to the aggregate amount of lives saved. Does contractualism really have this implication? If so, (...) should we side with the common-sense approach, or is there any reason to side with the contractualist? In this paper, I first examine a new argument from Jay Wallace which claims to reconcile contractualism with a duty to save the greater number. I find the argument to be unsuccessful. I then suggest that common-sense morality doesn't support a duty to save the greater number as straightforwardly as it might initially seem as it might initially seem. I introduce two mundane cases in which the permissibility of saving either the lesser or greater number is intuitively plausible, and I offer some reasons to think that the permissibility of saving the lesser number coheres with our value judgements more generally.

Many of us think that perspective-taking is relevant to moral judgment. In this paper I claim that Scanlon’s contractualism provides an appealing and distinctive account of why this is so. Contractualism interprets our moral judgments as making claims about the reasons of individuals in various situations, reasons that we can only recognise by considering their perspectives. Contractualism thereby commits itself to the view that our capacity for moral judgment depends on our capacity for perspective-taking. I show that neither utilitarianism nor (...) Kantianism assign a similar significance to our capacity for perspective-taking. (shrink)
