Practical wisdom enables moral decision-making and action by aligning one’s apprehension of proximate goods with a distal, socially embedded interpretation of a more ultimate Good. A focus on purpose within the overall process mutually informs human moral psychology and moral AI development in their examinations of practical wisdom. AI practical wisdom could ground an AI system’s apprehension of reality in a sociotechnical moral process committed to orienting AI development and action in light of a pluralistic, diverse interpretation of that Good. (...) Defining AI purpose in terms of the human struggle to determine the moral “ought” (versus the way reality is) can overcome practical and normative limitations of principle-based approaches to AI ethics without requiring idiosyncratic moral reasoning or a premature commitment to a single ethical theory, which could hinder navigating the moral implications of future unknowns. Dividing practical wisdom into proximate, mediating, and distal processes enables each division to incorporate the moral dimensions of the situation, individual AI system, and sociotechnical community, respectively. Drawing upon externalist (4E) and ecological cognitive psychology theories to extend Xavier Zubiri’s sentient intelligence, proximate apprehension of what an object affords the perceiver includes affordances for practical and moral purposes. Those apprehensions are structured by moral and other social-cognitive schemas that mediate moral constructs, the apprehended situation, and individual commitments and other motivating identifications in a process Ignacio Ellacuria calls historical reality. Distally, Josiah Royce’s community of interpretation characterizes one way of organizing a sociotechnical process to synthesize diverse interpretations of the Good, orient AI moral practice, and align AI development with human and AI moral purpose.

On a standard Aristotelian account, the moral virtues and vices stand in an asymmetric relationship to one another. To help explain this asymmetry, I argue that the vices share significantly less common structure than many think. That there are many ways for agents to get it wrong gives us prima facie reason to think that the vices lack a robust common structure. Further, the most promising candidates for a common structure of the vices fall short. These are that (a) the (...) vices have the common structure of being excesses and deficiencies, (b) the vices result from agents' unreflectively taking their inclinations as their ends, and, relatedly, (c) the vices result from rational corruption. Argument (b), which Terence Irwin and others endorse, is the most promising one, so I focus on it. But it, too, faces weighty objections. I conclude that none of these important arguments establishes the existence of a robust common structure of the moral vices. The great variety of moral vices is a puzzling phenomenon that continues to stand in need of explanation. (shrink)
