12 - On the Morality of Artificial Agents

Summary

Introduction: Standard versus Nonstandard Theories of Agents and Patients

Moral situations commonly involve agents and patients. let us define the class A of moral agents as the class of all entities that can in principle qualify as sources or senders of moral action, and the class P of moral patients as the class of all entities that can in principle qualify as receivers of moral action. A particularly apt way to introduce the topic of this paper is to consider how ethical theories (macroethics) interpret the logical relation between those two classes. There can be five logical relations between A and P; see Figure 12.1.

It is possible, but utterly unrealistic, that A and P are disjoint (alternative 5). On the other hand, P can be a proper subset of A (alternative 3), or A and P can intersect each other (alternative 4). These two alternatives are only slightly more promising because they both require at least one moral agent that in principle could not qualify as a moral patient. Now this pure agent would be some sort of supernatural entity that, like Aristotle's God, affects the world but can never be affected by it. Yet being in principle “unaffectable” and irrelevant in the moral game, it is unclear what kind of role this entity would exercise with respect to the normative guidance of human actions.
