Joshua Greene argues that cognitive (neuro)science matters for ethics in two ways, the “direct route” and the “indirect route.” Greene illustrates the direct route with a debunking explanation of the inclination to condemn all incest. The indirect route is an updated version of Greene’s argument that dual-process moral psychology gives support for consequentialism over deontology. I consider each of Greene’s arguments, and I argue that neither succeeds. If there is a route from cognitive (neuro)science to ethics, Greene has not found (...) it. (shrink)

In discussions about the ethics of enhancement, it is often claimed that the concept of ‘human nature’ has no helpful role to play. There are two ideas behind this thought. The first is that nature, human nature included, is a mixed bag. Some parts of our nature are good for us and some are bad for us. The ‘mixed bag’ idea leads naturally to the second idea, namely that the fact that something is part of our nature is, by itself, (...) normatively inert. The Inert View claims that nothing normative follows from the mere fact that some trait is a part of our nature. If the Inert View is correct, then appeals to the value or importance of human nature in debates about enhancement are indeed misplaced. We argue that the Inert View is wrong, and that a certain concept of human nature – which we refer to as human form – does have an important role to play in debates about enhancement. (shrink)

This essay is an analysis of the central arguments in Plato’s Crito. The dialogue shows, in a variety of ways, that the opinion of another person can have practical relevance in one’s deliberations about what to do – e.g. as an argument, as a piece of expert advice, as a threat. Especially important among these forms of practical relevance is the relevance of authoritative commands. In the dialogue, the Laws of Athens argue that Socrates must accept his sentence of death, (...) because he must regard the court’s verdict as a command from a practical authority – the city. The Laws’ arguments rely on special features of authority-reasons that many commentators have overlooked. This article explains why the Law’s arguments are unsuccessful. Finally, it is argued that Socrates’ description of ‘the many’ suggests that the city lacks the deliberative capacity necessary for possessing practical authority. (shrink)

In her Natural Goodness, Philippa Foot argues both that a distinctive grammar of goodness applies to living things generally, and that moral goodness in human beings is a special instance of natural goodness. My goal in this chapter is to provide a sympathetic interpretation of Foots’ grammar of goodness, clarifying and expanding it in a few places, and defending it against some objections. I begin by sketching Foot’s grammar. As I understand it, that grammar includes four main notions: 1) THE (...) GOOD OF, 2) GOOD AS / GOOD IN, 3) GOOD FOR, and 4) GOODS / GOOD THINGS. I then consider the relation between GOOD FOR, on the one hand, and THE GOOD OF and GOOD AS, on the other. Is it always GOOD FOR a living thing to be GOOD AS the kind of thing it is? Could something be GOOD FOR an organism without being part of THE GOOD OF that kind of thing? I argue that GOOD FOR, GOOD AS, and THE GOOD OF are inseparable: what is GOOD FOR a living thing just is that which furthers or constitutes THE GOOD OF such a creature, and THE GOOD OF any creature is the actualization of those well-formed capacities that make it GOOD AS the kind of creature that it is. In the final part of this chapter, I consider how happiness fits into Foot’s grammar of goodness as applied to human beings, paying special attention to the idea that THE GOOD OF any living thing consists in a certain form of activity.

Does possessing some human virtues make it impossible for a person to possess other human virtues? Isaiah Berlin and Bernard Williams both answered “yes” to this question, and they argued that to hold otherwise—to accept the harmony of the virtues—required a blinkered and unrealistic view of “what it is to be human.” In this essay, I have two goals: (1) to show how the harmony of the virtues is best interpreted, and what is at stake in affirming or denying it; (...) and (2) to provide a partial defense of the harmony of the virtues. More specifically, I show how the harmony of the virtues can be interpreted and defended within the kind of Aristotelian naturalism developed by philosophers such as Philippa Foot, Rosalind Hursthouse, and Michael Thompson. I argue that far from being an embarrassing liability for Aristotelianism—based in an “archaic metaphysical biology”—the harmony thesis is an interesting and plausible claim about human excellences, supported by a sophisticated account of the representation of life, and fully compatible with a realistic view of our human situation.
