I defend the following version of the ought-implies-can principle: (OIC) by virtue of conceptual necessity, an agent at a given time has an (objective, pro tanto) obligation to do only what the agent at that time has the ability and opportunity to do. In short, obligations correspond to ability plus opportunity. My argument has three premises: (1) obligations correspond to reasons for action; (2) reasons for action correspond to potential actions; (3) potential actions correspond to ability plus opportunity. In the (...) bulk of the paper I address six objections to OIC: three objections based on putative counterexamples, and three objections based on arguments to the effect that OIC conflicts with the is/ought thesis, the possibility of hard determinism, and the denial of the Principle of Alternate Possibilities.

Charles Beitz rejects two highly influential conceptions of international theory as empirically inaccurate and theoretically misleading. In one, international relations is a Hobbesian state of nature in which moral judgments are entirely inappropriate, and in the other, states are analogous to persons in domestic society in having rights of autonomy that insulate them from external moral assessment and political interference. Beitz postulates that a theory of international politics should include a revised principle of state autonomy based on the justice of (...) a state's domestic institutions, and a principle of international distributive justice to establish a fair division of resources and wealth among persons situated in diverse national societies.

Somalia, Haiti, Bosnia, and Kosovo. All are examples where humanitarian intervention has been called into action. This timely and important new volume explores the legal and moral issues which emerge when a state uses military force in order to protect innocent people from violence perpetrated or permitted by the government of that state. Humanitarian intervention can be seen as a moral duty to protect but it is also subject to misuse as a front for imperialism without regard to international law. (...) In Humanitarian Intervention, the contributors explore the many questions surrounding the issue. Is humanitarian intervention permitted by international law? If not, is it nevertheless morally permissible or morally required? Realistically, might not the main consequence of the humanitarian intervention principle be that powerful states will coerce weak ones for purposes of their own? The current debate is updated by two innovations in particular, the first being the shift of emphasis from the permissibility of intervening to the responsibility to intervene, and the second an emerging conviction that the response to humanitarian crises needs to be collective, coordinated, and preemptive. The authors shed light on the timely debate of when and how to intervene and when, if ever, not to. Contributors: Carla Bagnoli, Joseph Boyle, Anthony Coates, Thomas Franck, Brian D. Lepard, Catherine Lu, Pratap Bhanu Mehta, Terry Nardin, Thomas Pogge, Melissa S. Williams, and Kok-Chor Tan. (shrink)

The International Commission on Intervention and State Sovereignty's report, The Responsibility to Protect, argues that when a state is unable or unwilling to uphold its citizens? basic human rights, such as in cases of genocide, ethnic cleansing, and crimes against humanity, the international community has a responsibility to protect these citizens by undertaking humanitarian intervention. An essential issue, however, remains unresolved: which particular agent in the international community has the duty to intervene? In this article, I critically examine four ways (...) of assigning this duty. Although I highlight the benefits of institutionalising the responsibility to protect, I argue that we should adopt, in the short term at least, a consequentialist solution: humanitarian intervention should be the responsibility of the intervener that will be the most effective.

This essay explores the idea of just war in two ways. Part I outlines the formation, early development, and substantive content of just war tradition in its classic form, sketches the subsequent development of this idea in the modern period, and examines three benchmarks in the recovery of just war thinking in American thought over the last four decades. Part II identifies and critiques several prominent themes in contemporary just war discourse, testing them against the context, purpose, and content of (...) the just war idea in its classic form. My argument throughout is that the historical substance of just war tradition needs to be respected in contemporary just war discourse, both to discipline that discourse and to engage contemporary moral reflection with the values embodied in just war tradition.

The aim of this article is twofold. First, it is argued that while the principle of ‘ought implies can’ is certainly plausible in some form, it is tempting to misconstrue it, and that this has happened in the way it has been taken up in some of the current literature. Second, Kant's understanding of the principle is considered. Here it is argued that these problematic conceptions put the principle to work in a way that Kant does not, so that there (...) is an important divergence here which can easily be overlooked.

Have we any obligations beyond our own borders? What form do these take? These questions are addressed through a concept of comparative justice indebted to the just war tradition and the equal moral regard of persons.

Although we do not know exactly how many people die each year of malnutrition or related health problems, the number is very high, in the millions. By giving money to support famine relief efforts, each of us could save at least some of them. By not giving, we let them die.

Recently David Widerker argued that from the widely accepted ought implies can principle one can deduce the controversial and much discussed principle of alternative possibilities (PAP). Actually, he argues that this result is true only of the part of PAP which deals with moral blame. Because there are acts of supererogation, he maintains that it does not apply to the part which deals with moral praise. What Widerker says about supererogation seems true, and I develop and expand upon this idea (...) in the first half of the paper. Then I argue that Widerker's argument regarding moral blame fails.
