Can robots have significant moral status? This is an emerging topic of debate among roboticists and ethicists. This paper makes three contributions to this debate. First, it presents a theory – ‘ethical behaviourism’ – which holds that robots can have significant moral status if they are roughly performatively equivalent to other entities that have significant moral status. This theory is then defended from seven objections. Second, taking this theoretical position onboard, it is argued that the performative threshold that robots need (...) to cross in order to be afforded significant moral status may not be that high and that they may soon cross it (if they haven’t done so already). Finally, the implications of this for our procreative duties to robots are considered, and it is argued that we may need to take seriously a duty of ‘procreative beneficence’ towards robots.

Anscombe counsels us to dispense with those moral concepts that presuppose a divine law conception of ethics, among which she numbers the concepts of “moral obligation and moral duty, […] of what is morally right and wrong, and of the moral sense of ‘ought’.” Schopenhauer made a similar point more than a century earlier, though his critique implicates a narrower range of concepts. Through reflection on his accounts of right and wrong and of duty and obligation, this chapter attempts to (...) show that we can dispense with the imperative in ethics while retaining these notions, thus preserving a distinctively modern conception of morality.

Timothy Hsiao argues that animals lack moral status because they lack the capacity for the sort of higher-level rationality required for membership in the moral community. Stijn Bruers and László Erdős have already raised a number of objections to this argument, to which Hsiao has replied with some success. But I think a stronger critique can be made. Here I raise further objections to three aspects of Hsiao's view: his conception of the moral community, his idea of root capacities grounded (...) in one's nature, and his explanation of why cruelty is wrong. I also argue that sentience is a more plausible candidate for the morally salient capacity than rationality. (shrink)
