A critique of the ‘as–if’ approach to machine ethics

In this paper, I argue that the replication of the effect of ethical decision-making is insufficient for achieving functional morality in artificial moral agents (AMAs). This approach is named the “as–if” approach to machine ethics. I object to this approach on the grounds that the “as if” approach requires one to commit to substantive meta-ethical claims about morality that are at least unwarranted, and perhaps even wrong. To defend this claim, this paper does three things: 1. I explain Heidegger’s Enframing [Gestell] and my notion of “Ready-Ethics,” which, in combination, can hopefully provide a plausible account for the motivation behind the “as if” approach; 2. I go over specific examples of Ethical AI projects to show how the “as if” approach commits these projects to versions of moral generalism and moral naturalism. I then explain the flaws of the views that the “as if” approach necessitates, and suggest that they cannot account for the justificatory process crucial to human moral life. I explain how Habermas’ account of the justificatory process could cast doubt on the picture of morality that the meta-ethical views of the “as if” approach proposes; 3. Finally, I defend the relevance of discussing these topics for the purpose of functional morality in AMAs.

The Projectability Challenge to Moral Naturalism

The Projectability Challenge states that a metaethical view must explain how ordinary agents can, on the basis of moral experience and reflection, accurately and justifiably apply moral concepts to novel situations. In this paper, we argue for two primary claims. First, paradigm nonnaturalism can satisfactorily answer the projectability challenge. Second, it is unclear whether there is a version of moral naturalism that can satisfactorily answer the challenge. The conclusion we draw is that there is an important respect in which nonnaturalism holds an advantage over its most prominent naturalist rivals. The conclusion is interesting if only because it is widely assumed that naturalism has an easier time handling thorny problems in moral epistemology. We argue that there is at least one such problem of which this assumption is not true.

Naturalism and Moral Conventionalism

This article provides a critical examination of Ken Binmore’s theory of the social contract in light of philosophical discussions about moral naturalism and moral conventionalism. Binmore’s account builds on the popular philosophical device of the original position but gives it a naturalistic twist. I argue that this makes it vulnerable to moral skepticism. I explore a possible answer to the moral skeptic’s challenge, building on the fact that Binmore’s account displays a variant of moral conventionalism. I ultimately conclude however that the conventionalist answer leads to a purely behaviorist view of morality, which implies that there is nothing special about morality and fairness norms. I propose alternative interpretations of conventionalism. These accounts escape most of the difficulties because they place emphasis on the reasons that establish a moral convention.

Sustainability Ethics and Justice

This chapter identifies the basic elements of an ethic of sustainability, showing how principles of sustainability ethics can be derived from core commitments of common morality to respect others as rationally self-determining persons and to take care not to harm others. It goes on to define some cardinal virtues of sustainability ethics, frames a conception of politics as an art of sustainability, and outlines a theory of justice and just institutions that provide and preserve essential bases for living well. Some limitations of John Rawls’s theory of justice are examined as background to this approach, which can better conceptualize and guide the long-term preservation of opportunity to live well. Kant, Locke, Plato, and Aristotle also serve as philosophical points of reference. The approach is a methodological hybrid of moral naturalism and constructivism, and the pivotal claims about what is universally essential to human happiness and flourishing are based on decades of empirical studies in psychology.
