My philosophical case study concerns textbook presentations of the theory of demand. Does this theory contain anything more than just a collection of tautologies? In order to determine its empirical content, it must be viewed holistically. But then, the theory implies false factual claims. We can avoid this result by embracing the theory’s normative character. The resulting consequences will be illuminated with the new autodetermination thesis recently proposed in the philosophy of physics by Oliver Timmer. Applying his ideas to the (...) theory of demand reveals that the statements of this discipline simultaneously concern both values and facts. (shrink)

It is sometimes observed that the debate between internalists and externalists about moral motivation seems to have reached a deadlock. There are those who do, and those who don’t, recognize the intuitive possibility of amoralists: i.e. people having moral opinions without being motivated to act accordingly. This makes Sigrun Svavarsdóttir’s methodological objection to internalism especially interesting, since it promises to break the deadlock through building a case against internalism (construed as a conceptual thesis), not on such intuitions, but on a (...) methodological principle for empirical investigations. According to the objection, internalists incur the burden of argument, since they have to exclude certain explanations of the (verbal and non-verbal) behavior of apparent amoralists, while externalists don’t. In this paper I argue that the objection fails: the principle for empirical investigations is plausible, but Svavarsdóttir’s application of it to internalism is not. Once we clearly distinguish between the conceptual and the empirical aspects of the internalist and externalist explanations of apparent amoralists, we see that these views incur an equal burden of explanation. I end the paper with a positive suggestion to the effect that there is a third alternative, a view that involves accepting neither internalism nor externalism, which does not incur an explanatory burden of the relevant sort.

Concepts are mental representations that are the constituents of thought. EdouardMachery claims that psychologists generally understand concepts to be bodies of knowledge or information carrying mental states stored in long term memory that are used in the higher cognitive competences such as in categorization judgments, induction, planning, and analogical reasoning. While most research in the concepts field generally have been on concrete concepts such as LION, APPLE, and CHAIR, this paper will examine abstract moral concepts and whether such concepts may (...) have prototype and exemplar structure. After discussing the philosophical importance of this project and explaining the prototype and exemplar theories, criticisms will be made against philosophers, who without experimental support from the sciences of the mind, contend that moral concepts have prototype and/or exemplar structure. Next, I will scrutinize Mark Johnson’s experimentally-based argument that moral concepts have prototype structure. Finally, I will show how our moral concepts may indeed have prototype and exemplar structure as well as explore the further ethical implications that may be reached by this particular moral concepts conclusion.

Often our reason for doing something is an "instrumental reason": that doing that is a means to doing something else that we have reason to do. What principles govern this "instrumental transmission" of reasons from ends to means? Negatively, I argue against principles often invoked in the literature, which focus on necessary or sufficient means. Positively, I propose a principle, "General Transmission," which answers to two intuitive desiderata: that reason transmits to means that are "probabilizing" and "nonsuperfluous" with respect to (...) the relevant end. I then apply General Transmission to the debate over "detachment": whether "wide-scope" reason for a material conditional or disjunction implies "narrow-scope" reason for the consequent or disjuncts.

A discussion of epistemic reasons, theoretical rationality, and the relationship between them. Discusses the ontology of reasons and evidence, the relationship between reasons (motivating, normative, possessed, apparent, genuine, etc.) and rationality, the relationship between epistemic reasons and evidence, the relationship between rationality, justification, and knowledge, and many other related topics.

Consider the following three claims. (i) There are no truths of the form ‘p and ~p’. (ii) No one holds a belief of the form ‘p and ~p’. (iii) No one holds any pairs of beliefs of the form {p, ~p}. Irad Kimhi has recently argued, in effect, that each of these claims holds and holds with metaphysical necessity. Furthermore, he maintains that they are ultimately not distinct claims at all, but the same claim formulated in different ways. I find (...) his argument suggestive, if not entirely transparent. I do think there is at least an important kernel of truth even in (iii), and that (i) ultimately explains what’s right about the other two. Consciousness of an impossibility makes belief in the obtaining of the corresponding state of affairs an impossibility. Interestingly, an appreciation of this fact brings into view a novel conception of inference, according to which it consists in the consciousness of necessity. This essay outlines and defends this position. A central element of the defense is that it reveals how reasoners satisfy what Paul Boghossian calls the Taking Condition and do so without engendering regress. (shrink)

Philosophers are now wary of conflating the “fittingness” or accuracy of an emotion with any form of moral assessment of that emotion. Justin D’Arms and Daniel Jacobson, who originally cautioned against this “conflation”, also warned philosophers not to infer that an emotion is inaccurate from the fact that feeling it would be morally inappropriate, or that it is accurate from the fact that feeling it would be morally appropriate. Such inferences, they argue, risk committing “the moralistic fallacy”, a mistake they (...) claim is widespread throughout the work of contemporary and historical moral philosophers. I argue that many basic and familiar forms of moral assessment of the emotions are not subject to these arguments. I illustrate this by reconsidering the idea that to assess an emotion as “fitting” is to assess it as what a virtuous person would feel. After showing how assessments akin to this “virtue-theoretical” notion of fit may be prevalent even outside of the Aristotelian tradition, I suggest some more charitable and philosophically productive interpretations of the philosophical views of the emotions that D’Arms and Jacobson criticize, and argue that we cannot coherently theorize about the fittingness conditions of the emotions in a morally neutral way.

What is the relation between desire and action? According to a traditional, widespread and influential view I call ‘The Motivational Necessity of Desire’ (MN), having a desire that p entails being disposed to act in ways that you believe will bring about p. But what about desires like a desire that the committee chooses you without your needing to do anything, or a desire that your child passes her exams on her own? Such ‘self-passive’ desires are often given as a (...) counter-example to MN. If MN is true then self-passive desires seem absurd: if someone has a self-passive desire she will be disposed to act, thereby preventing her from getting what she desires. But it seems that we can reasonably, and often do, have such desires. However, I argue that self-passive desires are not, in fact, counter-examples to MN: close consideration of the content of these desires, the contexts in which we ascribe them, and what is claimed by MN show that they are not a problem for that view. I also argue that strengthened versions of the examples are unsuccessful, and I offer a diagnosis of why these kinds of case are commonly thought to raise a challenge to MN. (shrink)

This book is a defence of the philosophy of common sense in the spirit of Thomas Reid and G.E. Moore, drawing on the work of Aristotle, evolutionary biology and psychology, and historical studies on the origins of early modern philosophy. It defines and explores common sense beliefs, and defends them from challenges from prominent philosophers.

Sabina Lovibond invites her readers to see how the "practical reason view of ethics" can survive challenges from within philosophy and from the antirationalist postmodern critique of reason. She elaborates and defends a modern practical-reason view of ethics by focusing on virtue or ideal states of character that involve sensitivity to the objective reasons circumstances bring into play. At the heart of her argument is the Aristotelian idea of the formation of character through upbringing; these ancient ideas can be made (...) contemporary if one understands them in a naturalized way. She then explores the implications that arise from the naturalization of the classical view, weaving into her theory ideas of Jacques Derrida and J. L. Austin. The book also discusses two modes of resistance to an existing ethical culture--one committed to the critical employment of shared norms of rationality, the other aspiring to a more radical attitude, grounded in hostility to the "universal." Lovibond tries to determine what may be correct in this second, admittedly paradoxical, tendency. This is a timely and valuable effort to connect the most advanced forms of thinking in the analytic tradition and in the Continental tradition, and to extend our understanding of the intimacies and resistances between these two prominent strands of contemporary philosophy.

I argue against motivational internalism. First I recharacterise the issue over moral motivation. Second I describe the indifference argument against motivation internalism. Third I consider appeals to irrationality that are often made in the face of this argument, and I show that they are ineffective. Lastly, I draw the motivational externalist conclusion and reflect on the nature of the issue.

Abstract: This article addresses a number of difficulties and complications in the standard formulations of motivational internalism, and considers what besires might be in the light of those difficulties and complications. Two notions of besire are then distinguished, before considering how different kinds of motivational internalism and different conceptions of besire fare against the significant argument that we may be indifferent to the demands of morality without irrationality.

On one predominant conception of virtue, the virtuous agent is, among other things, wholehearted in doing what she believes best. I challenge this condition of wholeheartedness by making explicit the connections between the emotion of boredom and the states of continence and akrasia. An easily bored person is more susceptible to these forms of disharmony because of two familiar characteristics of boredom. First, that we can be – and often are – bored by what it is that we know would (...) be best to do, and second, that occurrent states of boredom tend to give rise to positive interest in performing actions that we know are bad to perform. Moreover, while a person’s susceptibility to boredom can indicate a lack of attentiveness or acuity, or be evidence of a vice such as ingratitude or shallowness, it can in others indicate positive qualities of character, such as perspicacity, liveliness, and certain forms of intelligence. Upon imagining certain bored akratics without the psychological qualities that give rise to their boredom, we will either imagine them without these positive qualities, or with others that – though perhaps psychologically possible – are not clearly better. This yields the result that a person who is continent or even akratic because of her susceptibility to boredom may have a character no less excellent than that of the wholehearted agent. (shrink)

Kant has argued that moral requirements are categorical. Kant's claim has been challenged by some contemporary philosophers; this article defends Kant's doctrine. I argue that Kant's claim captures the unique feature of moral requirements. The main arguments against Kant's claim focus on one condition that a categorical imperative must meet: to be independent of desires. I argue that there is another important, but often ignored, condition that a categorical imperative must meet, and this second condition is crucial to understanding why (...) moral requirements are not hypothetical. I also argue that the claim that moral requirements are not categorical because they depend on desires for motivation is beside the point. The issue of whether moral requirements are categorical is not an issue about whether moral desires or feelings are necessary for moral motivation but are rather an issue about the ground of moral desires or moral feelings. Moral requirements are categorical because they are requirements of reason, and reason makes moral desires or feelings possible. (shrink)

Every student of English-speaking analytical metaphysics is taught that the early twentieth century philosophical debate about truth confronted the correspondence theory, supported by Russell, Moore, the early Wittgenstein and, later, J.L. Austin, with the coherence theory advocated by the British Idealists. Sometimes the pragmatist conception of truth deriving from Dewey, William James, and C.S. Peirce is regarded as a third player. And as befits a debate at the dawn of analytical philosophy, the matter in dispute is normally taken to have (...) been the proper analysis of the concept.No doubt this conception nicely explains some of the characteristic turns taken in the debate. Analysis, as traditionally conceived, has to consist in the provision of illuminating conceptual equivalences; and illumination will depend, according to the standard rules of play, on the analysans’ utilizing only concepts which, in the best case, are in some way prior to and independent of the notion being analyzed — or, if that's too much to ask, then concepts which at least permit of some form of explication which does not in turn take one straight back to that notion.

Discussions of objectivity often start from considerations about disagreement. We might ask why this should be so. It makes it seem as though disagreement were surprising, but there is no reason why that should be so (the earliest thinkers in the Western tradition found conflict at least as obvious a feature of the world as concord). The interest in disagreement comes about, rather, because neither agreement nor disagreement is universal. It is not that disagreement needs explanation and agreement does not, (...) but that in different contexts disagreement requires different sorts of explanation, and so does agreement. (shrink)

ABSTRACT This paper considers the possibility and desirability of global ethics in light of the claim that ‘global ethics’ in any form is not global, but simply the imposition of one form of local ethics – Western ethics – and, as such, a form of moral neo‐colonialism. The claim that any form of global ethics is moral neo‐colonialism is outlined using the work of a group of ‘developing world bioethicists’ who are sceptical of the possibility of global ethics. The work (...) of virtue ethicists is then introduced and compared to the position of the developing world bioethicists in order to show that the divide between ‘Western’ and ‘non‐Western’ ethics is exaggerated. The final section of the paper turns to the practical arena and considers the question of global ethics in light of practical issues in bioethics. The paper concludes that practical necessity is driving the creation of global ethics and thus the pertinent question is no longer ‘Whether global ethics?’, but ‘Why global ethics?’. (shrink)

My title refers to three accounts of interpersonal love: the rationalist account that Terence Irwin ascribes to Plato; the anti-rationalist but strikingly similar account that Harry Frankfurt endorses in his own voice; and the ‘ekstatic’ account that I – following the lead of Martha Nussbaum – find in Plato's Phaedrus. My claim is that the ekstatic account points to important features of interpersonal love to which the other accounts fail to do justice, especially reciprocity and a regulative ideal of equality.

Moral particularists and generalists alike have struggled over how to incorporate the role of moral salience in ethical reasoning. In this paper, I point to neglected resources in Kant to account for the role of moral salience in maxim formation: Kant's theory of reflective judgment. Kant tasks reflective judgment with picking out salient empirical particulars for formation into maxims, associating it with purposiveness, or intentional activity (action on ends). The unexpected resources in Kantian reflective judgment suggest the possibility of a (...) particularist universalism, where recalcitrant particulars directly inform, and in some cases revise, moral principles. Such an account improves on particularist accounts of moral salience and moral perception: rather than deriving moral sensitivity solely from an agent's upbringing or cultural resources, the reflective dimension is situated alongside the universalist dimension of moral principles typically identified with Kantian ethics, allowing for a critical approach both to moral universals and to the reception of moral particulars.

‘Internalism’ is used in metaethics for a cluster of claims which bear a family resemblance. They tend to link, in some distinctive way—typically modal, mereological, or causal—different parts of the normative realm, or the normative and the psychological. The thesis of this paper is that much metaethical mischief has resulted from philosophers’ neglect of the distinction between two different features of such claims. The first is the modality of the entire claim. The second is the relation between the items specified (...) in the claim. In part one I explain this distinction and the problems neglecting it may cause. In part two I show that it has been neglected, and has caused those problems, at least with respect to one version of internalism. That is judgment internalism, which claims that moral beliefs are necessarily related to pro- or con-attitudes; e.g., that if you believe you ought to x you must have some motivation to x. The considerations standardly adduced in favor of judgment internalism support only a version which lacks the metaethical implications typically attributed to it, at least so far as anyone has shown. Proponents and opponents of judgment internalism fail to realize this because of their neglect of the modality/relation distinction. I illustrate by considering discussions of judgment internalism by Russ Shafer-Landau, Simon Blackburn, James Dreier, David Brink, and others. (shrink)

Constitutivists have tried to answer Enoch’s “schmagency” objection by arguing that Enoch fails to appreciate the inescapability of agency. Although these arguments are effective against some versions of the objection, I argue that they leave constitutivism vulnerable to an important worry; namely, that constitutivism leaves us alienated from the moral norms that it claims we must follow. In the first part of the paper, I try to make this vague concern more precise: in a nutshell, it seems that constitutivism cannot (...) provide an adequate account of the relation between the constitutive norms of agency and the particular ends the agent pursues. I then provide a broad outline of an interpretation of Kant’s formalism that is immune to this objection. I conclude that constitutivism is best understood as the upshot of a formalist view of categorical practical principles. (shrink)

Here are some kinds of reasons for taking an action to have been morally right. It was done out of a good intention or a pure good will on the part of the agent, or was owed to a virtue of hers. It issued from the agent's moral perception or intuition with respect to a situation, not from the application of a general principle or from calculation of the consequences of possible actions. Although it would give rise to distress or (...) worse, the action was one of integrity, autonomy, or self-concern, perhaps in accord with the agent's aversion to killing by her own hand, or true to her life-hope to achieve a success on her own.

What is the relation between the concept good and more specific or ‘thick’ concepts such as admirable or courageous? I argue that good or more precisely good pro tanto is a general concept, but that the relation between good pro tanto and the more specific concepts is not that of a genus to its species. The relation of an important class of specific evaluative concepts, which I call ‘affective concepts’, to good pro tanto is better understood as one between a (...) determinable and its determinates, whereas concepts such as courageous can be analysed in terms of affective concepts and purely descriptive concepts.

Evaluative concepts and emotions appear closely connected. According to a prominent account, this relation can be expressed by propositions of the form ‘something is admirable if and only if feeling admiration is appropriate in response to it’. The first section discusses various interpretations of such ‘Value-Emotion Equivalences’, for example the Fitting Attitude Analysis, and it offers a plausible way to read them. The main virtue of the proposed way to read them is that it is well-supported by a promising account (...) of emotions, namely the Perceptual Theory of Emotions, which emphasises the analogies between emotions and sensory perceptual experiences. The second section considers a worry about whether concepts such as admirable are really evaluative. It is maintained that even though the arguments used to show that thick terms and concepts are not inherently evaluative can be transposed to affective concepts, these arguments can be resisted. So there is no need to abandon the intuitive claim that affective concepts are inherently evaluative. (shrink)

Moral platonism, the claim that moral entities are both objective and prescriptive, is generally thought to be a dead end. In an attempt to defend a moderate form of moral platonism or more precisely platonism about values, I first argue that several of the many versions of this doctrine are not committed to ontological extravagances. I then discuss an important objection due to John McDowell and developed by Michael Smith, according to which moral platonism is incoherent. I argue that objectivism (...) is compatible with the claim that certain ways of being aware of values, namely those involving emotions, are motivating. (shrink)

In an overlooked section of his influential book What We Owe to Each Other Thomas Scanlon advances an argument against the desire-model of practical reasoning. In Scanlon’s view the model gives a distorted picture of the structure of our practical thinking. His idea is that there is an alternative to the “weighing behavior” of reasons, a particular way in which reasons can relate to each other. This phenomenon, which the paper calls “silencing”, is not something that the desire-model can accommodate, (...) or so Scanlon argues. The paper first presents and interprets Scanlon’s challenge. After this, the paper argues, through the examination of three responses, that Scanlon is right in claiming that the model cannot accommodate the phenomenon as he describes it. However, the paper further argues that there is no need to accept Scanlon’s depiction of silencing: advocates of the model can give an alternative account of what happens in cases of silencing that is just as plausible as Scanlon’s own. Scanlon’s challenge is thus, the paper concludes, illegitimate. (shrink)

The article begins with Jonathan Dancy’s attempt to refute the Humean Theory of Motivation. It first spells out Dancy’s argument for his alternative position, the view he labels ‘Pure Cognitivism’, according to which what motivate are always beliefs, never desires. The article next argues that Dancy’s argument for his position is flawed. On the one hand, it is not true that desire always comes with motivation in the agent; on the other, even if this was the case, it would still (...) not follow that desire is identical with the state of being motivated. When this negative work is done, the article turns to some positive, albeit admittedly tentative remarks about what sort of cognitivist theory of motivation one should endorse. The aim at this point is not to present a brand new theory, but rather to sketch an alternative that stems from what Dancy himself says and is in line with many of his endorsed commitments in other areas. In this way, by moving beyond Pure Cognitivism, the paper sketches a different, but still ‘Dancyesque’ theory of motivation. (shrink)

John Hare has proposed “prescriptive realism” in an attempt to stake out a middle-ground position in the twentieth century Anglo-American debates concerning metaethics between substantive moral realists and antirealist-expressivists. The account is supposed to preserve both the normativity and objectivity of moral judgments. Hare defends a version of divine command theory. The proposal succeeds in establishing the middle-ground position Hare intended. However, I argue that prescriptive realism can be strengthened in an interesting way.

ABSTRACTI defend the Interdependency Thesis, according to which rational evaluations of dispositions and actions are made in light of each other. I invoke a model of rationality that relies on various levels of consistency existing between an agent's reasons for adopting a moral disposition, the argument for the moral theory she endorses, her desires, disposition, and choice to be a moral person as reflected in the maxim she adopts. The Interdependency Thesis shows that we do not need to demonstrate the (...) rationality of every morally required action in order to defeat scepticism fully. (shrink)

According to the established understanding of the Frege-Geach problem, it is a challenge exclusively for metaethical expressivism. In this paper, I argue that it is much wider in scope: The problem applies generally to views according to which moral sentences express moral judgments entailing that one is for or against something, irrespective of what mental states the judgments consist in. In particular, it applies to motivational internalism about moral judgments. Most noteworthy, it applies to cognitivist internalism according to which moral (...) judgments consist in motivating beliefs. Hence, in order for a metaethical view to evade the Frege-Geach problem, it should avoid stating that moral judgments are motivating. (shrink)

One of the most discussed challenges to metaethical expressivism is the embedding problem. It is widely presumed that the reason why expressivism faces this difficulty is that it claims that moral sentences express non-cognitive states, or attitudes, which constitute their meaning. In this paper, it is argued that the reason why the embedding problem constitutes a challenge to expressivism is another than what it usually is thought to be. Further, when we have seen the real reason why expressivism is vulnerable (...) to this difficulty, it is plausible to argue that it makes up a challenge to certain other metaethical views as well.

The Nicomachean Ethics opens with some preparatory, although important, claims about the nature of the end for which all other things we do are said to be means. After having labelled this end “the highest good,” Aristotle asks: “Will not the knowledge of it, then, have a great influence on our way of life, and would we not [as a consequence] be more likely to attain the desired end, like archers who have a mark to aim at?”1 The question is (...) never explicitly considered, but an affirmative answer presupposed. We have thus at least some reason to believe that Aristotle embraces a species of internalism when it comes to moral motivation, although, admittedly, Aristotle’s initial formulation is weak. He does not say that there is any necessary link between someone knowing that an act has the indicated role and being motivated to perform it, just that someone’s knowledge somehow will influence him in that direction. Nevertheless, we will see that Aristotle can be interpreted as an internalist of the qualified kind in the Nicomachean Ethics. It is reasonable to claim that Aristotle there embraces a specific sort of internalism, to the effect that a person is motivated to perform the acts which are virtuous for him to perform, actions which will make him happy, unless he suffers from some sort of epistemic defect. A person who is virtuous can be said to know what happiness is, and such a person is motivated to perform actions that result in happiness. Moreover, Aristotle can be interpreted as an internalist in the Humean tradition, in the sense that in order to be motivated to perform an action, desires are needed as well as beliefs. (shrink)

Contemporary virtue ethicists widely accept thethesis that a virtuous agent''s feelings shouldbe in harmony with her judgments about what sheshould do and that she should find virtuousaction easy and pleasant. Conflict between anagent''s feelings and her actions, by contrast,is thought to indicate mere continence – amoral deficiency. This ``harmony thesis'''' isgenerally taken to be a fundamental element ofAristotelian virtue ethics.I argue that the harmony thesis, understoodthis way, is mistaken, because there areoccasions where a virtuous agent will findright action painful and (...) difficult. What thismeans is that the generally accepteddistinction between continence and virtue isunsupportable. This conclusion affects severalwell-known accounts of virtuous action,including those of Philippa Foot and JohnMcDowell. A closer look at Aristotle, however, providesanother way of distinguishing betweencontinence and virtue, based in hiscategorization of goods as noble or base. Iargue that virtue is exhibited when anagent''s feelings harmonize with his correctjudgments of value, while discrepancies betweenfeelings and correct judgments of valueindicate continence. This understanding ofcontinence and virtue enables us to accommodatethe problem cases I raise. (shrink)

I argue that there is a continuum of judgments ranging from those that are affectively rich, what might be called passionate judgments, to those that are purely cognitive and nonaffective, what might be called dispassionate judgments. The former are akin to desires and other affective states and so are necessarily motivating. Applying this schema to moral judgments, I maintain that the motivational internalist is wrong in claiming that all moral judgments are necessarily motivating, but right in regard to the subset (...) of passionate moral judgments. This picture of moral judgments has implications for related debates in metaethics between cognitivists and non-cognitivists and between Humeans and anti-Humeans. (shrink)

One argument put forward by Christine Korsgaard in favour of her constructivist appeal to the nature of agency, is that it does better than moral realism in answering moral scepticism. However, realists have replied by pressing on her the worry raised by H. A. Prichard, that any attempt to answer the moral sceptic only succeeds in basing moral actions in non-moral ends, and so is self-defeating. I spell out these issues in more detail, and suggest that both sides can learn (...) something by seeing how the sceptical problematic arises in Kant. Doing so, I argue, shows how Korsgaard might raise the issue of scepticism against the realist whilst avoiding the Prichardian response.1. (shrink)
