Alejo José G. Sison and Dulce M. Redín take a critical look at the concept of autonomous moral agents (AMAs), especially in relation to artificial intelligence (AI), from a neo-Aristotelian ethical standpoint. The authors open with a compelling critique of the arguments in favor of AMAs, asserting that they are neither inevitable nor guaranteed to bring practical benefits. They elucidate that the term ‘autonomous’ may not be fitting, as AMAs are, at their core, bound to the algorithmic instructions they follow. Moreover, the term ‘moral’ is questioned due to the inherent external nature of the proposed morality. According to the authors, the true moral good is internally driven and cannot be separated from the agent nor the manner in which it is achieved.
The authors proceed to suggest that the arguments against the development of AMAs have been insufficiently considered, proposing a neo-Aristotelian ethical framework as a potential remedy. This approach places emphasis on human intelligence, grounded in biological and psychological scaffolding, and distinguishes between the categories of heterotelic production (poiesis) and autotelic action (praxis), highlighting that the former can accommodate machine operations, while the latter is strictly reserved for human actors. Further, the authors propose that this framework offers greater clarity and coherence by explicitly denying bots the status of moral agents due to their inability to perform voluntary actions.
Lastly, the authors explore the potential alignment of AI and virtue ethics. They scrutinize the potential for AI to impact human flourishing and virtues through their actions or the consequences thereof. Herein, they feature the work of Vallor, who has proposed the design of “moral machines” by embedding norms, laws, and values into computational systems, thereby, focusing on human-computer interaction. However, they caution that such an approach, while intriguing, may be inherently flawed. The authors also examine two possible ways of embedding ethics in AI: value alignment and virtue embodiment.
The research article provides an interesting contribution to the ongoing debate on the potential for AI to function as moral agents. The authors adopt a neo-Aristotelian ethical framework to add depth to the discourse, providing a fresh perspective that integrates virtue ethics and emphasizes the role of human agency. This perspective brings to light the broader philosophical questions around the very nature of morality, autonomy, and the distinctive attributes of human intelligence.
Future research avenues might revolve around exploring more extensively how virtue ethics can interface with AI and if the goals that Vallor envisages can be realistically achieved. Further philosophical explorations around the assumptions of agency and morality in AI are also needed. Moreover, studies examining the practical implications of the neo-Aristotelian ethical framework, especially in the realm of human-computer interaction, would be invaluable. Lastly, it may be insightful to examine the authors’ final suggestion of approaching AI as a moral agent within the realm of fictional ethics, a proposal that opens up a new and exciting area of interdisciplinary research between philosophy, AI, and literature.
Abstract
We examine Van Wynsberghe and Robbins (JAMA 25:719-735, 2019) critique of the need for Artificial Moral Agents (AMAs) and its rebuttal by Formosa and Ryan (JAMA 10.1007/s00146-020-01089-6, 2020) set against a neo-Aristotelian ethical background. Neither Van Wynsberghe and Robbins (JAMA 25:719-735, 2019) essay nor Formosa and Ryan’s (JAMA 10.1007/s00146-020-01089-6, 2020) is explicitly framed within the teachings of a specific ethical school. The former appeals to the lack of “both empirical and intuitive support” (Van Wynsberghe and Robbins 2019, p. 721) for AMAs, and the latter opts for “argumentative breadth over depth”, meaning to provide “the essential groundwork for making an all things considered judgment regarding the moral case for building AMAs” (Formosa and Ryan 2019, pp. 1–2). Although this strategy may benefit their acceptability, it may also detract from their ethical rootedness, coherence, and persuasiveness, characteristics often associated with consolidated ethical traditions. Neo-Aristotelian ethics, backed by a distinctive philosophical anthropology and worldview, is summoned to fill this gap as a standard to test these two opposing claims. It provides a substantive account of moral agency through the theory of voluntary action; it explains how voluntary action is tied to intelligent and autonomous human life; and it distinguishes machine operations from voluntary actions through the categories of poiesis and praxis respectively. This standpoint reveals that while Van Wynsberghe and Robbins may be right in rejecting the need for AMAs, there are deeper, more fundamental reasons. In addition, despite disagreeing with Formosa and Ryan’s defense of AMAs, their call for a more nuanced and context-dependent approach, similar to neo-Aristotelian practical wisdom, becomes expedient.
