This is the second volume of Oxford Studies in Political Philosophy. Since its revival in the 1970s political philosophy has been a vibrant field in philosophy, one that intersects with jurisprudence, normative economics, political theory in political science departments, and just war theory. OSPP aims to publish some of the best contemporary work in political philosophy and these closely related subfields. The papers in this volume address a range of central topics and represent cutting edge work in the field. They are grouped into three main themes: ideal theory, the moral assessment of states, and issues in social reliations.

François Huet (1814-1869), a French philosopher, sought to reconcile the principles of Christianity with those of socialism. He argues that each person is entitled to the wealth he/she produces and to an equal share of the wealth from natural resources and from artifacts inherited from previous generations. Unlike Colins, Huet holds that agents have the right to give and bequeath wealth that they have created, but no such right with respect to wealth they inherited or received as a gift. (This view was later endorsed and modified by Rignano.).

This book contains the historically most important discussions of the philosophical foundations of left-libertarianism. Like the more familiar right-libertarianism (such as that of Nozick), left-libertarianism holds that agents own themselves (and thus owe no service the others expect as the result of voluntary action). Unlike right-libertarianism, however, left-libertarianism holds that natural resources are owned by the members of society in some egalitarian manner, and may be appropriated only with their permission, or with a significant payment to them.

Amartya Sen and Martha Nussbaum have argued that justice is concerned, at least in part, with the distribution of capabilities (opportunities to function). Richard Arneson, G.A. Cohen, and John Roemer have argued that justice is concerned with something like the distribution of opportunities for well-being. I argue that, although some versions of the capability view are incompatible with some versions of the opportunity for well-being view, the most plausible version of the capability view is identical to a slight generalization of the opportunity for well-being view.

Act teleological theories are theories that judge an action permissible just in case its outcome is maximally good.[1] It is usually assumed that act teleological theories cannot be @i, i.e., make the permissibility of actions depend on what the past was like (e.g., on what promises were made, what wrong doings were done, and more generally on what actions were performed).[2] I shall argue that this is not so. Although @u act teleological theories, such as classical act utilitarianism, are not past-regarding, there are other types of act teleological theories that are past-regarding.

In Child versus Childmaker Melinda Roberts provides an enlightening analysis and a cogent defense of a version of the person-affecting restriction in ethics. The rough idea of this restriction is that an action, state of affairs, or world, cannot be wrong, or bad, unless it would wrong, or be bad for, someone. I shall focus solely on Roberts’s core principles, and thus shall not address her interesting chapter-length discussions of wrongful life cases and of human cloning cases. The person-affecting intuition can be spelled out in a deontic and in an axiological form: Deontic Person-Affecting Restriction: An action, state of affairs, or world is wrong only if it would wrong someone. Axiological Person-Affecting Restriction: An action, state of affairs, or world is worse than another only if it is worse for someone. Roberts develops and defends the deontic version of the person-affecting restriction. Indeed, as her discussion (and those of others) makes clear, it is quite unlikely that there is a coherent version of the axiological form of the intuition (e.g., because of problems of transitivity). Roberts rightly rejects any appeal to impersonal ranking of worlds, and appeals only to the (many) personal rankings of worlds of the individuals involved. Roberts defends the view that worlds in which a person does not exist can be ranked in terms of that person’s well-being (how good that world would be for him/her) along with the worlds in which he/she does exist. Worlds in which the person has a life worth living are ranked more highly for that person than worlds in which he/she doesn’t exist (along with some worlds with indifferent existence), and the latter worlds are ranked more highly than worlds in which the person exists but doesn’t have a life worth living. Although this is somewhat controversial (some would deny that we can assess how good a world is for a person who doesn’t exist in it), it seems exactly right to me. Throughout I shall assume, as does Roberts, that non-existence has a value of zero (and thus that lives worth living have positive values, and that lives not worth living have negative values). In what follows I shall formulate Roberts’s theory as a theory of the permissibility of actions. In most of the book, Roberts formulates her theory as one of the permissibility of worlds, but, as I shall argue below, such assessments have little normative relevance, since they ignore the probabilities of realization (which depend on what actions are performed). The core of Roberts’s theory is just as plausible, and in some ways more powerful, when (as is sometimes the case in the book) it takes actions to be the objects of assessment. To start with, however, I shall make a highly restrictive assumption (not made by Roberts) that will effectively eliminate the difference between assessing actions and assessing worlds within the sort of welfaristic consequentialist framework that Roberts presupposes. I shall assume that if a given action were performed, then a specific world would be realized. We shall assume, that is, that there are no uncertainties involved. Everything is completely determined by which of the feasible actions is performed. Later in this paper, I will address the problems that arise once this simplifying assumption is dropped.
