Within a single paragraph in his Treatise of Human Nature, David Hume prompted what has become one of the most central orthodoxies in ethical theory: the thesis that one cannot derive what ought to be from what there is. In the aftermath of Hume’s seminal discussion, the No-Ought-From-Is-thesis has obtained approval among moral theorists to the point that it has been assigned the status of an undisputed ‘law’. As common with commonplaces in philosophy, alas, both the exact content and argument (...) of ‘Hume’s Law’ have proven to be quite elusive. The present anthology aims to clarify and discuss several controversies surrounding the No-Ought-From-Is-thesis. (shrink)

Kantian moral theories must explain how their most basic moral values of dignity and autonomy should be interpreted and applied to human conditions. One place Kantians should look for inspiration is, surprisingly, the utilitarian tradition and its emphasis on generally accepted, informally enforced, publicly known moral rules of the sort that help us give assurances, coordinate our behavior, and overcome weak wills. Kantians have tended to ignore utilitarian discussions of such rules mostly because they regard basic moral principles as a (...) priori requirements that cannot be tailored to human foibles and limitations. I argue that Kantian moral theories should incorporate public moral rules as mid-level moral requirements for embodied and socially embedded human agents. I explain how certain specific moral judgments about how we ought to act are justified by public moral rules, which are themselves justified by more fundamental moral requirements. (shrink)

In this commentary, I critically discuss the respective views of Gert and Beauchamp–Childress on the nature of so-called common morality and its promise for enriching ethical reflection within the field of bioethics. Although I endorse Beauchamp and Childress’ shift from an emphasis on ethical theory as the source of moral norms to an emphasis on common morality, I question whether rouging up common morality to make it look like some sort of ultimate and universal foundation for morality, untouched by the (...) dialectics of time and reflective equilibrium, was an equally good move. As for Gert’s magisterial conception of common morality, I conclude that certain elements of his system are controversial at best and woefully inadequate at worst. He has a tendency to find in common morality what he himself put there, and his highly restricted conception of duties of assistance strikes this reader as ad hoc, inadequately defended, and unworthy of a project whose goal is to lessen the amount of misery in the world.
