Moral relativists often defend their view as an inference to the best explanation of widespread and deep moral disagreement. Many philosophers have challenged this line of reasoning in recent years, arguing that moral objectivism provides us with ample resources to develop an equally or more plausible method of explanation. One of the most promising of these objectivist methods is what I call the self-interest explanation, the view that intractable moral diversity is due to the distorting effects of our interests. In (...) this paper I examine the self-interest explanation through the lens of the famine debate, a well-known disagreement over whether we have a moral obligation to donate most of our income to the global poor. I argue that objectivists should reduce their confidence that the persistence of the famine debate is due to the distorting influence of self-interest. If my argument is on target, then objectivists may need to supply a stronger explanation of moral disagreement to defend their view against the threat of moral relativism. (shrink)

People disagree about whether individuals in rich countries like the United States have an obligation to aid the world’s poorest people. A tempting thought is that this disagreement comes down to a non-moral matter. I argue that we should be suspicious of this view. Drawing on psychological evidence, I show that we should be more pessimistic about our ability to attribute the disagreement to a difference in factual beliefs.

Recent decades have seen a shift away from the traditional view that Aquinas's theory of the natural law is meant to supply us with normative guidance grounded in a substantive theory of human nature. In the present essay, I argue that this is a mistake. Expanding on the suggestions of Jean Porter and Ralph McInerny, I defend a derivationist reading of ST I-II, Q. 94, A. 2 according to which Aquinas takes our knowledge of the genuine goods of human life (...) and their proper ordering to one another to be self-evident only to the wise who are able to discern the truth about our God-given human nature. I then show that this reading provides a better account of Aquinas's view than two recent alternatives: John Finnis's brand of inclinationism and Daniel Mark Nelson's virtue-based interpretation.

Alasdair MacIntyre has developed a theory of the rationality of traditions that is designed to show how we can maintain both the tradition-bound nature of rationality, on the one hand, and non-relativism, on the other. However, his theory has been widely criticized. A number of recent commentators have argued that the theory is either inconsistent with his own conception of rationality or else is dependent on the standards of his particular tradition and therefore fails to defuse the threat of relativism. (...) In the present essay, I argue that this objection is mistaken. (shrink)

Disagreement has been grist to the mills of sceptics throughout the history of philosophy. Recently, though, some philosophers have argued that widespread philosophical disagreement supports a broad scepticism about philosophy itself. In this paper, I argue that the task for sceptics of philosophy is considerably more complex than commonly thought. The mere fact that philosophical methods fail to generate true majority views is not enough to support the sceptical challenge from disagreement. To avoid demanding something that human reasoning cannot supply, (...) sceptics must show that philosophers have sufficient overlap to resolve their disagreements in particular concrete cases.

Faced with endlessly repeated opportunities to save drowning children, most people think morality intuitively permits us to indulge in at least some goods that are not nearly as important as a child’s life. Some philosophers argue that this intuition gives us an important (though defeasible) reason to think we may sometimes permissibly refuse to save a life even when we can do so at insignificant cost. I argue that recent psychological experiments should make us wary of this claim.

A common response to ongoing disagreement about abortion has been to look for overlap between the prolife and prochoice sides of the debate. In recent years, however, both opposing camps in the debate have claimed to be able to establish their respective positions on the basis of the same common ground. Faced with the apparent failure of philosophers to settle their differences about abortion by means of shared values, the question naturally arises: what should we do about this? It is (...) possible to discern two main options in the scholarly literature. The first is to keep doing what we are already doing: namely, trying to create consensus on the abortion issue by appealing to analogies designed to reveal common ground. One example of this approach comes from a recent attempt by Charles Camosy to find areas of agreement with Peter Singer and other defenders of abortion.See Charles Camosy, “Common Ground on Surgical Abortion?—Engaging Peter Singer on the Moral Status of Potential Persons,”.

Recent years have seen a number of interpreters defend the claim that Nietzsche’s perspectivism is an epistemological doctrine. This interpretation of perspectivism leads to the worry that Nietzsche cannot offer any arguments for his view by means of which he may convince his opponents. To rescue Nietzsche from this justificatory problem, some interpreters have recently turned to the notion of “internal reasons,” or reasons that have force within multiple perspectives because they are based on shared standards. In this paper I (...) show that the task for supporters of Nietzsche is considerably more complex than it may seem at first sight. I argue that there is no way to know in advance of empirical investigation on a case-by-case basis whether perspectivism can be saved from undermining any compelling reasons that Nietzsche might provide in its defense.

Cells in the basal metazoan phylum Cnidaria are characterized by remarkable plasticity in their differentiation capacity. The mechanism controlling asymmetric cell divisions is not understood in cnidarians or in any other animal group. PIWI proteins recently have been shown to be involved in maintaining the self‐renewal capacity of stem cells in organisms as diverse as ciliates, flies, worms and mammals. Seipel et al.1 find that, in the cnidarian Podocoryne carnea, the Piwi homolog Cniwi is transcriptionally upregulated when the polyp (...) generates buds, which will develop into medusae. Since transdifferentiation of striated muscle cells to smooth muscle cells also activated Cniwi expression, Cniwi appears to play a crucial role in differentiation events. The discovery should facilitate elucidation of the poorly understood factors that control asymmetric cell divisions at the beginning of animal evolution.

Abastract The article analyses the intense public debate between the author Martin Walser and Ignatz Bubis caused by Walser's speach on the occasion of the award of the »Friedenspreis des Deutschen Buchhandels 1998«. lt argues that the conflict is based on two different conceptions of democratic public, public moral, and the function of moral elites in public. Both conceptions have religious implications and analogies in traditional theological conceptions of social corporations.
