In at least some of their forms, Cost-Benefit techniques for the evaluation of environmental projects and policies treat the preferences of citizens as the sole determinants of the value of outcomes. There are two salient ways in which this supposition might be defended. The first is metaethical and appeals to considerations about how we must understand talk of environmental and other values. The second is political and appeals to considerations about democratic legitimacy and the proper aims of public policy. Metaethical (...) considerations, I argue, are something of a red herring here. Roughly subjectivist understandings of our talk of values may be appealingly metaphysically unassuming, but in their most plausible formulations they do not support a view of preferences as the sole determinants of value. Political considerations, on the other hand, are to be taken very seriously. They offer, however, no straightforward rationale for any crudely preferentialist measure of social value. Findings obtained from the use of cost-benefit techniques might sometimes have a legitimate role as an input into, but not as a substitute for, political deliberation. Questions about the scope and limits of such legitimacy are properly addressed in political and not in metaethical terms. (shrink)

This article seeks to diagnose a serious defect in a highly influential supposed counterexample to utilitarianism: Bernard Williams's case of Jim and the Indians. Discussing this, Williams argues that, according to utilitarianism, it is obviously right to say that Jim should kill an Indian. But as this is not obviously right, Williams takes the example to furnish a forceful counterexample to utilitarianism. I note here that the force of the supposed counterexample is in fact very doubtful as the utilitarian can (...) readily enough explain the non-obviousness of the claim that Jim should kill with reference to the non-obviousness of utilitarianism itself.

Since the publication of Jonathan Dancy's 'Moral Reasons' in 1991, many English speaking ethicists have been especially interested in the role of abstract theory in moral life and the extent to which principles analogous to those employed in the hard sciences like physics are central to the development of ethical knowledge. Unlike earlier generations of philosophers who had, on the whole, accepted that principles had an integral role in the life of a morally serious person, contemporary ethicists are largely divided (...) about the merits of such principles and whether ethical knowledge is gained through principles. This debate about the form of ethical knowledge raises questions about the epistemic status of intuitions. Can intuitions about right and wrong provide an alternative source of genuine ethical knowledge? Is reflection upon a belief enough to show that it is true? This edited collection, consisting of 11 essays by distinguished philosophers, pursues and advances that debate. The early chapters of the book are concerned primarily with intuitions and intuitionism. John Cottingham, in an essay that casts doubt on the possibility of secular intuitions, argues that if intuitions are uprooted from their traditional theological foundations then they lose their plausibility. The claim is that theism and moral intuitionism are natural partners and morality is doomed if we reject theistic picture that 'provides a home for these intuitions'. James Lenman provides an indirect response to Cottingham, questioning whether evolutionary explanations of intuitions genuinely debunk them. Explaining the causal origins of intuitions within a naturalistic framework is not damning of them or of morality itself. (shrink)

This is a short review of James Lenman and Yonatan Shemmer's (eds.) collection of articles Constructivism in Practical Philosophy.

Recent studies indicate that mammalian chromosomes contain discretecis‐acting loci that control replication timing, mitotic condensation, and stability of entire chromosomes. Disruption of the large non‐coding RNA gene ASAR6 results in late replication, an under‐condensed appearance during mitosis, and structural instability of human chromosome 6. Similarly, disruption of the mouse Xist gene in adult somatic cells results in a late replication and instability phenotype on the X chromosome. ASAR6 shares many characteristics with Xist, including random mono‐allelic expression and asynchronous replication timing. (...) Additional “chromosome engineering” studies indicate that certain chromosome rearrangements affecting many different chromosomes display this abnormal replication and instability phenotype. These observations suggest that all mammalian chromosomes contain “inactivation/stability centers” that control proper replication, condensation, and stability of individual chromosomes. Therefore, mammalian chromosomes contain four types ofcis‐acting elements, origins, telomeres, centromeres, and “inactivation/stability centers”, all functioning to ensure proper replication, condensation, segregation, and stability of individual chromosomes.

While "moral naturalism" is sometimes used to refer to any approach to metaethics intended to cohere with naturalism in metaphysics more generally, the label is more usually reserved for naturalistic forms of moral realism according to which there are objective moral facts and properties and these moral facts and properties are natural facts and properties. Views of this kind appeal to many as combining the advantages of naturalism and realism but have seemed to many others to do inadequate justice to (...) central dimensions of our practice with our moral concepts. This entry examines some of these concerns and some ways in which moral naturalists have responded to them. It also profiles central aspects of the more particular views of some leading contemporary advocates of moral naturalism. (shrink)

The article investigates the resources of contractualist moral theory to make sense of the ethics of risk imposition. In some ways, contractualism seems well placed to explain how it can be reasonable to accept exposure to risk of harms whose direct imposition would not be acceptable. However, there are difficulties getting clear about what directness comes to here, especially given the difficulty of adequately motivating traditional views that assign ethical significance to what the agent intends as opposed to merely foreseeing. (...) The article considers two principles which might help the contractualist: the Redistribution Principle, which, while attractive, is perhaps somewhat too restrictive, and the Aim Consistency Principle, which grants ethical significance to the aims with which our actions are in principle consistent whatever our actual intentions may be. The article also considers the relative significance of ex ante and ex post perspectives from which to evaluate actions and principles. Key Words: contractualism • Doctrine of Double Effect • ethics • intention • justice • risk • T.M. Scanlon • utilitarianism. (shrink)

Moral Expressivists typically concede that, in some minimal sense, moral sentences are truth-apt but claim that in some more robust sense they are not. The Immodest Disciplined Syntacticist, a species of minimalist about truth, raises a doubt as to whether this contrast can be made out. I here address this challenge by motivating and describing a distinction between reducibly and irreducibly truth-apt sentences. In the light of this distinction the Disciplined Syntacticist must either adopt a more modest version of his (...) theory, friendlier to Expressivism, or substantially modify it, abandoning one of its central conditions on truth-aptness. One natural and promising such modification, the Pure Discipline View, is described and its implications for an understanding of Expressivism briefly discussed. (shrink)

This volume presents twelve original papers on the idea that moral objectivity is to be understood in terms of a suitably constructed social point of view that all can accept.

From an impersonal, timeless perspective it is hard to identify good reasons why it should matter that human extinction comes later rather than sooner, particularly if we accept that it does not matter how many human beings there are. We cannot appeal to the natural narrative shape of human history for there is no such thing. We have more local and particular concerns to which we can better appeal but only if an impersonal, timeless perspective is abandoned: only from a (...) generation–centred perspective do such concerns help to make sense of our concern for the timing of our own extinction.

My concern here is with the Humean claim that no purely cognitive state could, in combination with appropriate other beliefs, but with nothing else, originate a process of rational motivation. The starting point of such motivation must always include some other element: a desire. Let's call this claim, following David McNaughton the belief-desire theory, or BDT for short. The theory is widely believed but intensely controversial. I argue here that it is true.

Let me say something, to begin with, about wanting weird stuff. Stuff like saucers of mud. The example, famously, is from Anscombe’s Intention (Anscombe Anscombe 957)) where she is, in effect, defending a version of the old scholastic maxim, Omne appetitum appetitur sub specie boni. If your Latin is rusty like mine, what that says is just that every appetite – for better congruence with modern discussions, let’s say every desire – desires under the aspect of the good, or in (...) the wording made current by Velleman, under the guise of the good (Velleman 992). To desire something is to regard it as good in some way, as having some desirability characteristic. And not just any old thing can be regarded as good in some way, as having some desirability characteristic. Obviously if this is correct, it rules against our giving desires any sort of ground-floor role in our understand-. (shrink)

Modern philosophical literature distinguishes between explanatory reasons and justifying reasons. The former are reasons we appeal to in attempting to explain actions and attitudes. The latter are reasons we appeal to in attempting to justify them.

Parfit argues that naturalistic theories that seek to understand normative concepts either as simply descriptive of certain natural facts about our desires or as expressive of our desires commit us to a bleak normative nihilism whereby nothing matters. I here defend such naturalism, in particular its expressivist variety, against this charge. It is true that such views commit us to there being no reasons as Parfit understands them. But for Parfit to suppose that equivalent to there being no reasons leaves (...) him begging the question where the relative credibility of these rival understandings is just what is at issue. 1.

It has recently been argued by Cian Dorr that if noncognitivism is true, inferences to factual conclusions from premises at least one of which is moral must be condemned as irrational. For, given a noncognitivist understanding of what it is to accept such premises, such reasoning would be wishful thinking: irrationally revising our views about the world to make them cohere with our desires and feelings. This he takes to be a reductio of noncognitivism. I argue that no compelling case (...) to this effect has been made out. I show how, in many cases, non-cognitivists can make excellent sense of the rational legitimacy of such arguments. In cases where they plausibly cannot do so, moreover, this legitimacy is highly doubtful for independently plausible reasons and should be doubted even by cognitivists. (shrink)

Smith has defended the rationalist's conceptual claim that moral requirements are categorical requirements of reason, arguing that no status short of this would make sense of our taking these requirements as seriously as we do. Against this I argue that Smith has failed to show either that our moral commitments would be undermined by possessing only an internal, contextual justification or that they need presuppose any expectation that rational agents must converge on their acceptance. His claim that this rationalistic understanding (...) of metaethics is required for the intelligibility of moral disagreement is also found to be inadequately supported. It is further proposed that the rationalist's substantive claims – that therearesuch categorical requirements of reason and that our actual moral commitments are a case in point – are liable to disappointment; and that the conceptual claim is fatally undermined by reflection on how we might best respond to such disappointment. (shrink)

I argue against the claim that we should adopt a moral error theory. The intelligibility of our moral practice need offer no questionable metaphysical hostages to fortune. The two most credible policy recommendations that might follow from moral error theory, abolitionism and prescriptive fictionalism, are not very credible.

Those whose Way is not the same cannot take counsel together.Confucius, Analects XV, 40Quasi-Realism and Fundamental Disagreement: Egan’s ProblemI believe that it is wrong to open your boiled egg at the big end. You believe that it is not wrong to open your egg at the big end. We are at an impasse. The impasse might not be deep. One of us might just be wrong on some matter of prosaic nonnormative fact. But perhaps that is not the case. Even (...) if we both came to be fully informed about all relevant facts, our disagreement might persist. Perhaps other rational means are available to resolve our disagreement. Perhaps if I became more sensitive, more imaginative, more considerate of others’ needs, I would change my mind. And perhaps, by my own present lights, one’s moral sensibility is improved by being changed in these ways, so that this would be, again by my own present lights, a change for the better. Perhaps your contrary view would not prove robust in circumstances where you had to endu. (shrink)

Vaesen infers unique properties of mind from the appearance of specific cultural innovation – a correlation without causal direction. Shifts in habitat, population density, and group dynamics are the only independently verifiable incentives for changes in cultural practices. The transition from Acheulean to Late Stone Age technologies requires that we consider how population and social dynamics affect cultural innovation and mental function.

Ridge defends a form of hybrid expressivism where normative judgements are constituted by two elements, normative perspectives and representational beliefs that invoke standards our normative perspectives determine. He thinks this view will enable him to ‘offload logical complexity’ onto the latter, representational components of our judgements, thereby taming the Frege-Geach Problem and conferring a dialectical advantage over non-hybrid, ‘pure’ forms of expressivism. But this will only work if our normative perspectives are themselves consistent in ways that are resistant to such (...) offloading. There are, moreover, serious problems with building normative perspectives into what we understand by moral judgement that appear best tamed by thinning out our understanding of them in ways that effectively collapse the ecumenical form of expressivism back into its purer cousin. The supposed dialectical advantage proves, I argue, chimerical. (shrink)

The first English translation of Fichte’s second set of 1804 lectures on the Wissenschaftslehre.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

1. Brian Hedden, in this impressively learned and ingenious, if somewhat maddening book,1 1 defends a view he calls Time-slice Rationality, a view comprising two central claims. They are: Synchronicity : All requirements of rationality are synchronic. Impartiality : In determining how you rationally ought to be at a time, your beliefs about what attitudes you have at other times play the same role as your beliefs about what attitudes other people have.
