In this paper I describe cases of moral blackmail as cases where A is told by B that if A does not commit an otherwise immoral act, B will commit an immoral act of equal or greater gravity. I describe cases of moral dilemma as cases where A must commit an otherwise immoral act to avert a natural disaster of equal or greater gravity. I then argue that cases of moral blackmail are structurally identical to cases of moral dilemma in all respects but one: In cases of moral blackmail, A is predicting the free actions of a moral agent (B), whereas in cases of moral dilemma, A is predicting natural events. I conclude that cases of moral blackmail are more problematic than otherwise similar cases of moral dilemma for this reason alone.

This essay explains for a general philosophical audience the central issues and strategies in the contemporary moral realism debate. It critically surveys the contribution of some recent scholarship, representing expressivist and pragmatist nondescriptivism (Mark Timmons, Hilary Putnam), subjectivist and nonsubjectivist naturalism (Michael Smith, Paul Bloomfield, Philippa Foot), nonnaturalism (Russ Shafer-Landau, T. M. Scanlon) and error theory (Richard Joyce). Four different faces of ‘moral realism’ are distinguished: semantic, ontological, metaphysical, and normative. The debate is presented as taking shape under dialectical pressure from the demands of (i) capturing the moral appearances and (ii) reconciling morality with our understanding of the mind and world.

I distinguish two different arguments against cognitivism in Bernard Williams’ writings on moral dilemmas. The first turns on there being a truth of the matter about what we ought to do in moral a dilemma. That argument can be met by appealing to our epistemic shortcomings and to pro tanto obligations. However, those responses make no headway with the second argument which concerns the rationality of the moral regret that we feel in dilemma situations. I show how the rationality of moral regret can be explained on an ‘independent desire’ model. And I show how Williams’ second argument only appears to have force because of a certain faulty way of conceiving of the issue over cognitivism. But Williams’ argument rightly alerts us to the rational role of desire in our moral thought.

Moral disagreement is widely held to pose a threat for metaethical realism and objectivity. In this paper I attempt to understand how it is that moral disagreement is supposed to present a problem for metaethical realism. I do this by going through several distinct (though often related) arguments from disagreement, carefully distinguishing between them, and critically evaluating their merits. My conclusions are rather skeptical: Some of the arguments I discuss fail rather clearly. Others supply with a challenge to realism, but not one we have any reason to believe realism cannot address successfully. Others beg the question against the moral realist, and yet others raise serious objections to realism, but ones that—when carefully stated—can be seen not to be essentially related to moral disagreement. Arguments based on moral disagreement itself have almost no weight, I conclude, against moral realism.

This paper defends moral realism against Sharon Street’s “Darwinian Dilemma for Realist Theories of Value” (this journal, 2006). I argue by separation of cases: From the assumption that a certain normative claim is true, I argue that the first horn of the dilemma is tenable for realists. Then, from the assumption that the same normative claim is false, I argue that the second horn is tenable. Either way, then, the Darwinian dilemma does not add anything to realists’ epistemic worries.

Moral Dilemmas is the second volume of collected essays by the eminent moral philosopher Philippa Foot, gathering the best of her work from the late 1970s to the 1990s. It fills the gap between her famous 1978 collection Virtues and Vice (now reissued) and her acclaimed monograph Natural Goodness, published in 2001. In this new collection, Professor Foot develops further her critique of the dominant ethical theories of the last fifty years, and discusses such topics as the nature of moral judgement, practical rationality, and the conflict of virtue with desire and self-interest. Moral Dilemmas, alongside her other two books, completes the summation of her distinctive and lasting contribution to twentieth-century moral philosophy.

In this article the author criticizes Michael Devitt’s Naturalistic Moral Realism, as well as that program in general. The author argues the following: moral explanations do not work; the fact that moral featuressupervene on the non-moral ones does not support the thesis of Realism; moral principles can not be tested like factual ones; Moral Realists Naturalists water down their thesis so much that it ceases to be a form of realism; there are no moral observations in any interesting sense.

It is sometimes alleged that “the reliability challenge” to moral realism is equally compelling against mathematical realism. This allegation is of interest. The reliability challenge to moral realism is increasingly taken to be the most serious challenge to moral realism. However, the specific considerations that are said to motivate it – such as considerations of rational dubitability and evolutionary influence – are widely held not to motivate an analogous challenge to mathematical realism. If it turned out that, in fact, they do, then one might have to choose between moral realism and mathematical realism.

Nevertheless, the relevant allegation has never been clarified, let alone evaluated. In this paper, I clarify and evaluate it. I argue that the allegation is plausible, but depends on theses in the philosophy of mathematics that are widely doubted. One upshot of the discussion is that mathematical realism faces challenges that have not been widely appreciated. Another is that the reliability challenge to moral realism may not be the most interesting epistemological challenge to moral realism.
