The argument proceeds from a sense of imminent danger; 9/11 and its sequel challenge our deepest pretensions regarding the universality and self-evidence of moral/political conviction. The intransigence of such convictions is now an important source of international conflict and terror. It also signifies that the resolution of the disorder that now confronts the international community requires a transformation in our conception of morality itself. In this regard, philosophy has an important task to address. The discussion explores a radical change in (...) our understanding of just war, the distinction between war and peace, the logic of conflict, and similar topics. (shrink)

I have recently argued that if the causal theory of reference is true, then, on pain of absurdity, no normative ethical theory is true. In this journal, Michael Byron has objected to my reductio by appealing to Frank Jackson’s moral reductionism. The present essay defends reductio while also casting doubt upon Jackson’s moral reductionism.

Where does normativity come from? Or alternatively, in virtue of what do facts about what an agent has reason to do obtain? On one class of views, reason facts obtain in virtue of agents’ motivations. It might seem like a truism that at least some of our reasons depend on what we desire or care about. However, some philosophers, notably Derek Parfit, have convincingly argued that no reasons are grounded in this way. Typically, this latter, externalist view of reasons has (...) been thought to enjoy the advantage of extensional adequacy—that is, the ability to account for all the reasons we intuitively think people have. This paper provides a novel argument against this assumption by considering a type of case wherein the relative strengths of the agent’s reasons can only be adequately explained by reference to what she cares about. Adding some further assumptions yields that there are at least some internally sourced reasons. (shrink)

In ethics, ‘probabilism’ refers to a position defended by a number of Catholic theologians, mainly in the sixteenth and seventeenth centuries. They held that, when one is uncertain which of a range of actions is the right one to perform, it is permissible to perform any which has a good chance of being the right one—even if there is another which has a better chance. This paper considers the value of this position from the viewpoint of modern ethical philosophy. The (...) unusual nature of probabilism as a theory focusing upon permissibility, rather than right-making properties, is explored and related to some modern attempts to set out ‘satisficing’ and ‘hybrid’ ethical theories. Such theories try to distinguish between what is best and what is permissible, and probabilism can be understood as an alternative way of supplementing a theory of right-making properties by adding to it a theory of permissibility. But a more radical version is also possible, where one abandons any attempt to identify right actions or right-making properties, and instead considers permissibility alone. Accordingly, a ‘multi-account theory’ of permissibility is proposed and defended as a model of how many people actually make moral decisions. (shrink)

Natural theology is still practiced as though substantive theological conclusions can be derived by a quasi-deductive process. Perhaps relevant "evidence" may lead to interesting theological conclusions -- the fact of natural evil, or the cosmic fine-tuning we hear about in contemporary cosmology, both cry out for theological explanation. I remain a skeptic, however, about the value of "a priori" methods in natural theology. The case study in this short discussion is the well known attempt to establish the logical incoherence of (...) the divine command theory of moral objectivity. If skeptics can make good on this charge, they will have gone a long way toward undercutting a central tenant of western theism. I will argue, however, that the case against theologically based moral absolutism is not as simple as showing some internal paradox or logical tension. (shrink)

The so-called 'Extreme Claim' asserts that reductionism about personal identity leaves each of us with no reason to be specially concerned about his or her own future. Both advocates and opponents of the Extreme Claim, whether of a reductionist or non-reductionist stripe, accept that similar problems do not arise for non-reductionism. In this paper I challenge this widely held assumption.

John Rawls’s 1980 Dewey Lectures are widely acknowledged to represent the locus classicus for contemporary discussions of moral constructivism. Nevertheless, few published works have engaged with the significant interpretive challenges one finds in these lectures, and those that have fail to offer a satisfactory reading of the view that Rawls presents there or the place the lectures occupy in the development of Rawls's thinking. Indeed, there is a surprising lack of consensus about how best to interpret the constructivism of these (...) lectures. In this paper, I argue that the constructivism presented in the Dewey Lectures is best understood as involving the view that moral truth is correspondence with procedurally-determined, stance-dependent facts. Employing Rawls’s discussion of rational intuitionism as a foil, I defend this reading against textual discrepancies from within the lectures, as well as those one finds across Rawls’s other works. In addition to settling interpretive disputes, I draw out the ways in which this understanding of Kantian constructivism fits within the broader comparative project in ‘moral theory’ that Rawls inherits from Sidgwick.

Many naturalistically-minded philosophers want to accomplish a naturalistic reduction of normative (e.g. moral and epistemic) claims. Mindful of avoiding the naturalistic fallacy, such philosophers claim that they are not reducing moral and epistemic concepts or definitions. Rather, they are only reducing the extension of these normative terms, while admitting that the concepts possess a normative content that cannot be naturalistically reduced. But these philosophers run into a serious problem. I will argue that normative claims possess two dimensions of normativity. I (...) will further argue that certain of the reductionist’s commitments require that these two dimensions of normativity be given a naturalistic reduction, while the other of the reductionist’s commitments make such a reduction impossible. Thus, the reductionist’s commitments both require and forbid a reductionist account of morality and epistemology. Thus, as we will see, reductionism is torn between two incompatible requirements, and must fail. (shrink)

Moral rationalism has long been an attractive position within moral philosophy. However, among empirical-minded philosophers, it is widely dismissed as scientifically untenable. In this essay, I argue that moral rationalism’s lack of uptake in the empirical domain is due to the widespread supposition that moral rationalists must hold that moral judgments and actions are produced by rational capacities. But this construal is mistaken: moral rationalism’s primary concern is not with the relationship between moral judgments and rational capacities per se, but (...) rather with developing a conception objectivity normativity that avoids Platonism. In light of this, I develop an alternative approach to translating moral rationalism into the empirical domain that builds on the common rationalist view that normative requirements are explained by the relationship between agents and the social structures and practices in which they are embedded. I propose that this social conception of normativity can be translated into a scientific framework by interpreting it as a claim about the importance of constraint-based explanation when accounting for norm-governed behavior. In order to develop this point more concretely and show that it is empirically tractable, I turn to research on macaque social organization that highlights the ways in which normative standards are generated by empirically observable social structures. The insights garnered from the macaque case allow me to then locate moral rationalism’s core claims about the relationship between morality and the standards of practical rationality within an empirically plausible framework.

Katarzyna de Lazari-Radek and Peter Singer have recently provided an evolutionary argument for utilitarianism. They argue that most of our deontological beliefs were shaped by evolution, from which they conclude that these beliefs are unjustified. By contrast, they maintain that the utilitarian belief that everyone’s well-being matters equally is immune to such debunking arguments because it wasn’t similarly influenced. However, Guy Kahane remarks that this belief lacks substantial content unless it is paired with an account of well-being, and he adds (...) that utilitarian beliefs about wellbeing—e.g. the belief that pleasure is good and pain is bad—were probably shaped by evolution. Logically, de Lazari-Radek and Singer should therefore reject these beliefs along with the deontological beliefs that evolved. The present paper is a defense of their argument. After considering a number of unsuccessful replies to Kahane’s objection, I put forward a more promising solution: de Lazari-Radek and Singer should combine their objectivist view in metaethics with a subjectivist account of well-being, such as the desire theory. Such a hybrid account would tackle Kahane’s challenge because subjective accounts of value are immune from evolutionary debunking arguments. And it would be compatible with utilitarianism, which doesn’t fit very well with metaethical subjectivism. Before concluding, I deal with two concerns that this solution might raise: I argue that the desire theory is actually subjective enough to escape Kahane’s objection, and I deny that retreating to the combination of ethical objectivism and prudential subjectivism is ad hoc.

The moral error theory holds that moral claims and beliefs, because they commit us to the existence of illusory entities, are systematically false or untrue. It is an open question what we should do with moral thought and discourse once we have become convinced by this view. Until recently, this question had received two main answers. The abolitionist proposed that we should get rid of moral thought altogether. The fictionalist, though he agreed we should eliminate moral beliefs, enjoined us to (...) replace them with attitudes that resemble to some extent the attitudes we have towards pieces of fiction. But there is now a third theory on the market: conservationism, the view that we should keep holding moral beliefs, even though we know them to be false. (According to a fourth theory, ‘substitutionism’, we should modify the content of our moral claims in such a way that they become true.) Putting abolitionism (and substitutionism) aside, our aim is to assess the plausibility of conservationism as an alternative to the – relatively dominant – fictionalism that we find in the literature. Given the difficulty of finding a conservationist view that is both (i) plausible and (ii) not merely a terminological variant of fictionalism, we will argue that conservationism fails to constitute a plausible alternative to fictionalism, at least insofar as it purports to be an alternative view as to what we should do with our moral thoughts. (shrink)

According to the moral error theory, all moral judgments are false. Until lately, most error theorists were local error theorists; they targeted moral judgments specifically and were less skeptical of other normative areas. These error theorists now face so-called “prudential parity objections”, according to which whatever evidence there is in favor of the moral error theory is also evidence for a prudential error theory. The present paper rejects three prudential parity objections: one based on the alleged irreducible normativity of prudential (...) reasons; another on the lack of a story about the normativity of hypothetical reasons; yet another on the very nature of reasons generally. I argue that these objections leave an important variant of a local moral error theory intact. (shrink)

The moral error theory has become increasingly popular in recent decades. So much so indeed that a new issue emerged, the so-called “now-what problem”: if all our moral beliefs are false, then what should we do with them? So far, philosophers who are interested in this problem have focused their attention on the mode of the attitudes we should have with respect to moral propositions. Some have argued that we should keep holding proper moral beliefs; others that we should replace (...) our moral beliefs with fictional attitudes, beliefs in natural facts, or conative attitudes. But all these philosophers have set aside an important question about the content of these attitudes: which moral propositions, and more generally which moral theory, should we accept? The present paper addresses this neglected issue, arguing that moral error theorists should adopt a utilitarian moral fiction. In other words, they should accept the set of moral principles whose general acceptance would maximize overall well-being. (shrink)

If we are to assess whether our attitudes towards nature are morally, aesthetically or in any other way appropriate or inappropriate, then we will need to know what those attitudes are. Drawing on the works of Katie McShane, Alan Holland and Christine Swanton, I challenge the common assumption that to love, respect, honour, cherish or adopt any other sort of pro-attitude towards any natural X simply is to value X in some way and to some degree. Depending on how one (...) interprets ‘value’, that assumption is, I contend, either false or vacuous. I argue that to assess the appropriateness of a person’s pro-attitudes towards a natural entity one must in some cases appeal to the concepts of status and/or bond, and not just that of value. To develop my argument, I appeal to the works of two nature writers – Robert Macfarlane and J. A. Baker. (shrink)

Although much ink has been spilled on different aspects of legal concepts, the approach based on the developments of cognitive science is a still neglected area of study. The “mental” and cognitive aspect of these concepts, i.e., their features as mental constructs and cognitive tools, especially in the light of the developments of the cognitive sciences, is discussed quite rarely. The argument made by this paper is that legal concepts are best understood as mental representations. The piece explains what mental (...) representations are and why this view matters. The explanation of legal concepts, understood as mental representations is one of three levels of explanation within legal philosophy, but—as will be argued—it is the most fundamental level. This paper analyzes the consequences of such understanding of concepts used in the field of legal philosophy. Special emphasis is put on the current debate on the analogical or amodal nature of concepts. (shrink)

Michael Williams and Keith DeRose defend their different versions of contextualism on the grounds that contextualism gives a better account of the ordinary use of epistemic terms than invariantist competitors. One aim of this paper is to explain why their arguments do not succeed. A further aim is to show that the dispute between contextualists and invariantists portrayed by Williams and DeRose is a narrow interpretation of the dispute: there are important contextualist and invariantist positions which fall outside the scope (...) of their arguments and which a full defense of contextualism should consider.

Eighteenth-century disputes in moral theory seem to offer an opportunity to scepticism about moral theory and about morality. Twentieth-century theorists have tried to forestall a sceptical argument from disagreement in moral theory to doubts about morality, by appeal to a division between first-order and second-order questions. This division, however, does not answer the sceptical argument. A better reply appears in Butler's treatment of disagreement through his strategies of consensus and comprehension. These strategies are illustrated by his discussion of utilitarianism and (...) of the relation between conscience and self-love. (shrink)

Whewell and ShaftesburyIn contemporary moral philosophy ‘moral realism’ refers to a position in the metaphysics of morality that is analogous to realism about ordinary objects, and to scientific realism about theoretical entities. It is a realist doctrine in contrast to non-cognitivism, constructivism, fictionalism, and nihilism about moral judgments and moral properties. But while these particular contrasts are characteristic of contemporary philosophy, realism itself is much older. Ross, Prichard, and Sidgwick, for instance, hold realist views in the metaphysics of morals, though (...) they do not describe them in this way.As far as I know, the first person to use ‘moral realism’ as a description of a distinct tradition in modern moral philosophy is Whewell. He speaks of Shaftesbury as “the origin of a new school of real moralists” , who maintained some of the views of “the ancient school of Cudworth and Clarke”. Balguy is a member of this “old realist school” who defe .. (shrink)

We discuss how analysis of contemporary artworks has shaped philosophical theories about the concept of art, the ontology of art, and artistic media. The rapid expansion, during the contemporary period, of the kinds of things that can count as artworks has prompted a shift toward procedural definitions, which focus on how artworks are selected, and away from definitions that focus exclusively on artworks’ features or effects. Some contemporary artworks challenge the traditional art–ontological dichotomy between physical particulars and repeatable entities whose (...) occurrences are physical particulars. And nontraditional techniques and materials employed in contemporary art violate the boundaries of conventional media, prompting a rethinking of what artistic medium might be. (shrink)

Robust Realists think that there are irreducible, non-natural, and mind-independent moral properties. Quasi-Realists and Relaxed Realists think the same, but interpret these commitments differently. Robust Realists interpret them as metaphysical commitments, to be defended by metaphysical argument. Quasi-Realists and Relaxed Realists say that they can only be interpreted as moral commitments. These theories thus pose a serious threat to Robust Realism, for they apparently undermine the very possibility of articulating the robust metaphysical commitments of this theory. I clarify and respond (...) to this threat, showing that there is in fact space to develop and defend a robust moral ontology. (shrink)

Some philosophers object to moral error theory by arguing that there a parity between moral and epistemic normativity. They maintain that moral and epistemic error theory stand or fall together, that epistemic error theory falls, and that moral error theory thus falls too. This paper offers a response to this objection on behalf of moral error theorists. I defend the view that moral and epistemic error theory do not stand or fall together by arguing that moral error theory can be (...) sustained alongside epistemic expressivism. This unusual combination of theories can be underpinned by differences in the foundational norms that guide moral and epistemic inquiry. I conclude that the problem of epistemic normativity fails to show that it is compulsory for us to reject moral error theory. (shrink)

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and judgement are committed to the existence of moral (...) properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape.

This paper defends the thesis that counterfactuals are strict conditionals. Its purpose is to show that there is a coherent view according to which counterfactuals are strict conditionals whose antecedent is stated elliptically. Section 1 introduces the view. Section 2 outlines a response to the main argument against the thesis that counterfactuals are strict conditionals. Section 3 compares the view with a proposal due to Aqvist, which may be regarded as its direct predecessor. Sections 4 and 5 explain how the (...) view di ers from the theories of counterfactuals advocated by Stalnaker and Lewis, and from some contextualist strict conditional accounts of counterfactuals that have emerged recently. Finally, section 6 addresses the thorny issue of disjunctive antecedents. (shrink)

Fictionalism has recently returned as a standard response to ontologically problematic domains. This article assesses moral fictionalism. It argues (i) that a correct understanding of the dialectical situation in contemporary metaethics shows that fictionalism is only an interesting new alternative if it can provide a new account of normative content: what is it that I am thinking or saying when I think or say that I ought to do something; and (ii) that fictionalism, qua fictionalism, does not provide us with (...) any new resources for providing such an account.

In this essay I attempt to tease out and assess two arguments that pervade Sellars's writings on the practical sphere. The first is an argument that categorical reasonableness must be a part of any adequate account of practical reason. The second argues that, nonetheless, the Kantian's strong connection between morality and practical reasonableness cannot be defended. I argue that the former argument is a powerful and ingenious defense of a role for something more than hypothetical reasonableness in the practical sphere, (...) while the latter argument against a strong conceptual connection between morality and reason fails.

The logic of 'elsewhere,' i.e., of a sentence operator interpretable as attaching to a formula to yield a formula true at a point in a Kripke model just in case the first formula is true at all other points in the model, has been applied in settings in which the points in question represent spatial positions, as well as in the case in which they represent moments of time. This logic is applied here to the alethic modal case, in which (...) the points are thought of as possible worlds, with the suggestion that its deployment clarifies aspects of a position explored by John Divers under the name 'modal agnosticism.' In particular, it makes available a logic whose Halldén incompleteness explicitly registers the agnostic element of the position - its neutrality as between modal realism and modal anti-realism.

Skeptical hypotheses such as the brain-in-a-vat hypothesis provide extremely poor explanations for our sensory experiences. Because these scenarios accommodate virtually any possible set of evidence, the probability of any given set of evidence on the skeptical scenario is near zero; hence, on Bayesian grounds, the scenario is not well supported by the evidence. By contrast, serious theories make reasonably specific predictions about the evidence and are then well supported when these predictions are satisfied.

I defend the 'Repugnant' Conclusion that for any possible population of happy people, a population containing a sufficient number of people with lives barely worth living would be better. Four lines of argument converge on this conclusion, and the conclusion has a simple, natural theoretical explanation. The opposition to the Repugnant Conclusion rests on a bare appeal to intuition. This intuition is open to charges of being influenced by multiple distorting factors. Several theories of population ethics have been devised to (...) avoid the Repugnant Conclusion, but each generates even more counterintuitive consequences. The intuition opposing the Repugnant Conclusion is thus among the best candidates for an intuition that should be revised. (shrink)

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral stance.

Internalists about reasons generally insist that if a putative reason, R, is to count as a genuine normative reason for a particular agent to do something, then R must make a rational connection to some desire or interest of the agent in question. If internalism is true, but moral reasons purport to apply to agents independently of the particular desires, interests, and commitments they have, then we may be forced to conclude that moral reasons are incoherent. Richard Joyce (2001) develops (...) an argument along these lines. Against this view, I argue that we can make sense of moral reasons as reasons that apply to, and are capable of motivating, agents independently of their prior interests and desires. More specifically, I argue that moral agents, in virtue of their capacities for empathy and shared intentionality, are sensitive to reasons that do not directly link up with their pre-existing ends. In particular, they are sensitive to, and hence can be motivated by, reasons grounded in the desires, projects, commitments, concerns, and interests of others. Moral reasons are a subset of this class of reasons to which moral agents are sensitive. Thus, moral agents can be motivated by moral reasons, even where such reasons fail to link up to their own pre-existing ends. (shrink)

J. L. Mackie argued that if there were objective moral properties or facts, then the supervenience relation linking the nonmoral to the moral would be metaphysically queer. Moral realists reply that objective supervenience relations are ubiquitous according to contemporary versions of metaphysical naturalism and, hence, that there is nothing especially queer about moral supervenience. In this paper we revive Mackie's challenge to moral realism. We argue: (i) that objective supervenience relations of any kind, moral or otherwise, should be explainable rather (...) than sui generis; (ii) that this explanatory burden can be successfully met vis-à-vis the supervenience of the mental upon the physical, and in other related cases; and (iii) that the burden cannot be met for (putative) objective moral supervenience relations.

I argue for three principle claims. First, philosophers who seek to integrate the semantic and the intentional into a naturalistic metaphysical worldview need to address a task that they have thus far largely failed even to notice: explaining into- level connections between the physical and the intentional in a naturalistically acceptable way. Second, there are serious reasons to think that this task cannot be carried out in a way that would vindicate realism about intentionality. Third, there is much to be (...) said for an irrealist, non-eliminativist, naturalistic approach to intentionality that I call "preservative irrealism". (shrink)

Moral judgments are typically experienced as being categorically authoritative – i.e. as having a prescriptive force that is motivationally gripping independently of both conventional norms and one's pre-existing desires, and justificationally trumps both conventional norms and one's pre-existing desires. We argue that this key feature is best accommodated by the meta-ethical position we call ‘cognitivist expressivism’, which construes moral judgments as sui generis psychological states whose distinctive phenomenological character includes categorical authoritativeness. Traditional versions of expressivism cannot easily accommodate the justificationally (...) trumping aspect of categorical authoritativeness, because they construe moral judgments as fundamentally desire-like. Moral realism cannot easily accommodate the aspect of inherent motivational grip, because realism construes moral judgments as a species of factual belief. (shrink)

What is the significance of empirical moral psychology for metaethics? In this article we take up Michael Ruse’s evolutionary debunking argument against moral realism and reassess it in the context of the empirical state of the art. Ruse’s argument depends on the phenomenological presumption that people generally experience morality as objective. We demonstrate how recent experimental findings challenge this widely-shared armchair presumption and conclude that Ruse’s argument fails. We situate this finding in the recent debate about Carnapian explication and argue (...) that it illustrates the necessary role that empirical moral psychology plays in explication preparation. Moral psychology sets boundaries for reasonable desiderata in metaethics and, therefore, it is necessary for metaethics. (shrink)

How should we understand the notion of moral objectivity? Metaethical positions that vindicate morality’s objective appearance are often associated with moral realism. On a realist construal, moral objectivity is understood in terms of mind-, stance-, or attitude-independence. But realism is not the only game in town for moral objectivists. On an antirealist construal, morality’s objective features are understood in virtue of our attitudes. In this paper I aim to develop this antirealist construal of moral objectivity in further detail, and to (...) make its metaphysical commitments explicit. I do so by building on Sharon Street’s version of “Humean Constructivism”. Instead of the realist notion of attitude-independence, the antirealist account of moral objectivity that I articulate centres on the notion of standpoint-invariance. While constructivists have been criticized for compromising on the issue of moral objectivity, I make a preliminary case for the thesis that, armed with the notion of standpoint-invariance, constructivists have resources to vindicate an account of objectivity with just the right strength, given the commitments of ordinary moral thought and practice. In support of this thesis I highlight recent experimental findings about folk moral objectivism. Empirical observations about the nature of moral discourse have traditionally been taken to give prima facie support to moral realism. I argue, by contrast, that from what we can tell from our current experimental understanding, antirealists can capture the commitments of ordinary discourse at least as well as realists can.

Over the course of human history there appears to have been a global shift in moral values towards a broadly ‘liberal’ orientation. Huemer argues that this shift better accords with a realist than an antirealist metaethics: it is best explained by the discovery of mind-independent truths through intuition. In this article I argue, contra Huemer, that the historical data are better explained assuming the truth of moral antirealism. Realism does not fit the data as well as Huemer suggests, whereas antirealists (...) have underappreciated resources to explain the relevant historical dynamics. These resources include an appeal to socialization, to technological and economical convergences, to lessons learned from history, to changes induced by consistency reasoning and to the social function of moral norms in overcoming some of the cooperation problems that globalizing societies face. I point out that the realist’s explanans has multiple shortcomings, that the antirealist’s explanans has several explanatory virtues, and conclude that the latter provides a superior account of the historical shift towards liberal values.

Hobbes’s interpreters have struggled to find a plausible semantics for evaluative language in his writings. I argue that this search is misguided. Hobbes offers neither an account of the reference of evaluative terms nor a theory of the truth-conditions for evaluative statements. Rather, he sees evaluative language simply as having the non-representational function of prescribing actions and practical attitudes, its superficially representational appearance notwithstanding. I marshal the evidence for this prescriptivist reading of Hobbes on evaluative language and show how it (...) sidesteps various textual and philosophical problems that bedevil the traditional interpretations.

Karen Bennett argues that there is no distinct problem with metaphysics, and she proposes a disjunctive conception of the subject matter of metaphysics. This paper critically examines her arguments and positive view. I defend that metaphysics prima facie is distinctly problematic, and I raise some questions about Bennett’s disjunctive conception of the subject matter of metaphysics and the a priori aspect of its methodology.

Most scientists agree that; at least for the time being; unquantified uncertainties are inevitably connected to predictions of climate models. Uncertainties; however; do not justify political inaction. This paper addresses the question of how epistemic uncertainties are of relevance for practical decision making. It is shown how common decision approaches based on the precautionary principle fail to adequately deal with uncertainties as they arise in climate modeling. I argue that with regards to climate change; unquantified uncertainties can neither be ignored (...) in decision making nor be reduced to quantified ones by assigning subjective probabilities. This distinguishes the ethical problems associated with climate change from other problems regarding energy supply and demand like; for example; those associated with nuclear power. (shrink)

Verbunden mit dem drohenden Verlust von kognitiven Kapazitäten und der Veränderung der eigenen Persönlichkeit, ist zu vermuten, dass bei Demenzerkrankungen ein Sinnverlust vom Erkrankten befürchtet wird. Es ist Aufgabe dieses Papers aufzuklären, was es mit einer solch meist diffus empfundenen Angst auf sich hat.

Es wird gezeigt, dass es möglich ist, bis zu einem gewissen Grad der Demenz ein sinnvolles Leben zu führen – ein Leben, bei dem subjektiv (...)

It is an assumption common to many theories of rationality that all practical reasons are based on a person's given desires. I shall call any approach to practical reasons which accepts this assumption a "Humean approach". In spite of many criticisms, the Humean approach has numerous followers who take it to be the natural and inevitable view of practical reason. I will develop an argument against the Humean view aiming to explain its appeal, as well as to expose its mistake. (...) I focus on just one argument in favour of the Humean approach, which I believe can be constructed as the background idea of many Humean accounts: the argument from motivation. (shrink)

Alcohol intoxication is a major source of antisocial behavior in our society, strongly implicated in various forms of interpersonal aggression. Yet, moral philosophers have paid surprisingly little attention to the literature on alcohol and its effects. In part, this is because philosophers who have adopted a more empirically informed approach to moral psychology have gravitated toward moral sentimentalism, while the literature on alcohol intoxication fits very poorly with the sentimentalist account. Most contemporary research on the psychological effects of alcohol is (...) focused upon variants of the “disinhibition” theory, which suggests that alcohol does not provoke any specific affect, it merely weakens executive control. This research, we argue, lends support to a deontic moral psychology, which identifies our ability to suppress behavioral impulses as a central feature of moral agency. (shrink)

In this paper, I argue that Humean theories of moral motivation appear preferable to Kantian approaches only if one assumes a broadly foundationalist conception of rational justification. Like foundationalist approaches to justification generally, Humean psychology aims to counter the regress-of-justification argument by positing a set of ultimate regress-stoppers-in this case, unmotivated desires. If the need for regress-stoppers of this type in the realm of practical deliberation is accepted, desires do indeed appear to be the most likely candidate. But if this (...) foundationalist strategy is rejected, there is no longer any reason to suppose that all motivation must be traceable to some extra-rational incentive. This clears the way for a rehabilitation of the Kantian claim that reasons for action can take the form of categorical imperatives. To illustrate this thesis, I show how a conception of practical rationality that incorporates a contextualist model of justification can be developed that treats social norms as reasons for action, without assigning any mediating role to agent desires. a theory of action of this type eliminates the gap between moral obligation and action, and so articulates the fundamental Kantian intuition that acting on the basis of moral principle-and with disregard for self-interest-is just one way of acting rationally.
