In this paper I introduce my work in ethics, inviting others to draw on my approach to address the ethical issues that concern them. I set up the Centre for Ethical Philosophy at Durham University in 2007 to plug a puzzling gap in philosophical work to help us help the world. In 1. I set out ethical philosophy. In 2. I consider some implications, for example, that to do good we must pay much more attention to the beings around us, less to ourselves. In 3. I consider the implications for how we should think about war and peace. In 4. I draw out some implications for good political practice. In 5. I consider objections and conclude.

A threat to women is obscured when we treat “abortion-as-evacuation” as equivalent to “abortion-as-killing.” This holds only if evacuating a fetus kills it. As technology advances, the equivalence will fail. Any feminist account of abortion that relies on the equivalence leaves moral room for women to be required to give up their fetuses to others when it fails. So an account of the justification of abortion-as-killing is needed that does not depend on the equivalence.

In our philosophical tradition and our wider culture, we tend to think of persons as agents. This agential conception is flattering, but in this paper I will argue that it conceals a more complex truth about what persons are. In 1. I set the issues in context. In 2. I critically explore four features commonly presented as fundamental to personhood in versions of the agential conception: action, capability, choice and independence. In 3. I argue that each of these agential features presupposes a non-agential feature: agency presupposes patiency, capability presupposes incapability, choice presupposes necessity and independence presupposes dependency. In 4. I argue that such non-agential features, as well as being implicit within the agential conception, are as apt to be constitutive of personhood as agential features, and in 5. I conclude.

Aristotle’s account of human needs is valuable because it describes the connections between logical, metaphysical, physical, human and ethical necessities. But Aristotle does not fully draw out the implications of the account of necessity for needs and virtue. The proper Aristotelian conclusion is that, far from being an inferior activity fit only for slaves, meeting needs is the first part of Aristotelian virtue.

In this article we argue that the concept of need is as vital for moral theory as it is for moral life. In II we analyse need and its normativity in public and private moral practice. In III we describe simple cases which exemplify the moral demandingness of needs, and argue that the significance of simple cases for moral theory is obscured by the emphasis in moral philosophy on unusual cases. In IV we argue that moral theories are inadequate if they cannot describe simple needs-meeting cases. We argue that the elimination or reduction of need to other concepts such as value, duty, virtue or care is unsatisfactory, in which case moral theories that make those concepts fundamental will have to be revised. In conclusion, we suggest that if moral theories cannot be revised to accommodate needs, they may have to be replaced with a fully needs-based theory.

One of the most striking contributions of particularism to moral philosophy has been its emphasis on the relative opacity of the moral scene to the tools of rational analysis traditionally used by philosophers. Particularism changes the place of the philosopher in relation to the moral life, pointing up the limits to what philosophy can do here. The modern moral philosopher who takes particularism seriously no longer has the luxury, endemic in our tradition, of imagining that moral philosophy can be done with only passing illustrative reference to experience, or that the truth about the whole of our moral life may be read of a list of a priori moral principles, whose rationality is underwritten by the mechanistic account of what it is to follow a rule that pre-Wittgensteinian philosophers took for granted.
