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)

When policymakers craft rules for use by the general public, they must take into account the ways in which their rules are likely to be misapplied. Should contractualists and rule consequentialists do the same when they search for rules whose general acceptance would be non-rejectable or ideal? I argue that these theorists face a dilemma. If they ignore the possibility of misapplication, they end up with an unrealistic view that rejects rules designed to protect us from others’ mistakes. On the (...) other hand, if they take misapplication into account, they end up rejecting rules that appeal to what really matters morally in favor of easier-to-apply proxies for these rules. This leaves them unable to say why certain wrong acts are wrong, which in turn may lead them to mistaken verdicts about moral worth and wronging. I show how this misapplication dilemma applies to standard contractualist and rule consequentialist theories, but also suggest how it might generalize to other two-level theories, including those designed to avoid the ideal world objection.

This paper is a defence of T.M. Scanlon's contractualism - the view that an action is wrong if it is forbidden by the principles which no one could reasonably reject. Such theories have been argued to be redundant in two ways. They are claimed to assume antecedent moral facts to explain which principles could not be reasonably rejected, and the reasons they provide to follow the non-rejectable principles are said to be unnecessary given that we already have sufficient reasons not (...) to do the acts that are forbidden by those principles. In this paper, I try to argue that neither one of these claims is true. (shrink)

This article provides a critical introduction to contractualism as a moral or ethical theory, that is, as a theory of the rightness and wrongness of individual conduct – focusing specifically on the influential 'Kantian' version of contractualism due to T. M. Scanlon. I begin by elucidating the key features of Scanlon's contractualism: justifiability to others; reasonable rejectability; the individualist restriction; and mutual recognition. I then turn to discuss both its appeal and the main objections that have been raised to it (...) – objections concerning our duties to the cognitively limited and impaired, aggregation, demandingness, normativity and explanatory adequacy. I conclude by mentioning some contractualist alternatives to Scanlon's theory. (shrink)
