Moral discourse allows for speakers to disagree in many ways: about right and wrong acts, about moral theory, about the rational and conative significance of moral failings. Yet speakers’ eccentricities do not prevent them from engaging in moral conversation or from having (genuine, not equivocal) moral disagreement. Thus differences between speakers are compatible with possession of moral concepts. This paper examines various kinds of moral disagreements and argues that they provide evidence against conceptual-role and informational atomist approaches to understanding our (...) moral concepts. Conceptual role approaches fail because they cannot account for shared concepts among speakers with different commitments to the practical and conative ramifications of moral judgments. Informational atomist views fail because speakers need not be locked on to the same moral properties to share moral concepts. (shrink)

Philosophers have taken little heed of the fact that people often act contrary to their better judgment not because they suffer a volitional infirmity like weakness of will or compulsion but instead because they care too little about what they judge best (they are unconcerned) or they care too much about something else (they are compromised). Unconcerned and compromised action, being varieties of akratic action that do not involve volitional infirmity, are phenomena worth examining not only in their own right (...) but also for what they reveal about the better known varieties of akratic action for which they might easily be mistaken, such as weak-willed action and action (or inaction) that stems from accidie. Unconcern and compromise also are worth examining for what they reveal about a topic beyond philosophical psychology, namely, moral and legal accountability. Forgiveness, resentment, and retributive punishment each may have less to do with what an offender (morally) believes than with what he cares about. (shrink)

Realism has been a central object of attention among analytical philosophers for some decades. Starting from analytical philosophy, the return of realism has spread into other contemporary philosophical traditions and given birth to new trends in current discussions, as for example in the debates about “new realism.” Discussions about realism focused on linguistic meaning, epistemology, metaphysics, theory of action and ethics. The implications for politics of discussion about realism in action theory and in ethics, however, are not much discussed.

The purpose of this essay is twofold. First, I plan to argue that in light of Buddhist epistemology and metaphysics, it would be an inherent contradiction to the Buddhist tradition as whole to defend the cognitivist view that moral knowledge is possible. Quite the contrary, this essay will demonstrate that, in light of Buddhist theories of knowledge and metaphysical philosophies of no-self and emptiness, Buddhist ethics only makes coherent sense from a standpoint of non-cognitivism. Second, from the arguments that support (...) a non-cognitivist reading of Buddhist ethics, I plan to show that such a standpoint does not entail moral nihilism. Rather, what we find in Buddhism is a middle-way ethic of pluralism. Herein I shall argue that the moral life of Buddhism non-cognitively arises within skandha of feelings, yet is conditioned by the cognitive nature of Buddhist wisdom. (shrink)

In the first part of the article, an account of moral judgment in terms of emotional dispositions is given. This account provides an expressivist explanation of three important features of moral demands: inescapability, authority independence and meriting. In the second part of the article, some ideas initially put forward by Christopher Boehm are developed and modified in order to provide a hypothesis about the evolution of the ability to token moral judgments. This hypothesis makes evolutionary sense of inescapability, authority independence (...) and meriting. It does so by referring to the selection pressures generated in the Late Pleistocene by large-game hunting. If the hypothesis is correct, we can say that, in a sense, meat made us moral. (shrink)

In this paper we present an analysis of persuasive definition based on argumentation schemes. Using the medieval notion of differentia and the traditional approach to topics, we explain the persuasiveness of emotive terms in persuasive definitions by applying the argumentation schemes for argument from classification and argument from values. Persuasive definitions, we hold, are persuasive because their goal is to modify the emotive meaning denotation of a persuasive term in a way that contains an implicit argument from values. However, our (...) theory is different from Stevenson’s, a positivistic view that sees emotive meaning as subjective, and defines it as a behavioral effect. Our proposal is to treat the persuasiveness produced by the use of emotive words and persuasive definitions as due to implicit arguments that an interlocutor may not be aware of. We use congruence theory to provide the linguistic framework for connecting a term with the function it is supposed to play in a text. Our account allows us to distinguish between conflicts of values and conflicts of classifications. (shrink)

Supervenience has provided a way for nonreductive materialists to explain how the mental can be physically irreducible but still physically respectable. In recent years, doubts about this research program have emerged from a number of quarters. Consequently, Terence Horgan has argued that nonreductive materialists must appeal to an upgraded "superdupervenience," if supervenience is to do any materialist work. We argue that nonreductive materialism cannot meet this challenge. Superdupervenience is impossible.

If reduction of the social to the physical fail, what options remain for understanding their relationship? Two such options are supervenience and constructivism. Both are vitiated by a similar fault. So the choices are limited: reduction after all, or emergence.

Since the middle of the last century, normative language has been much studied. In particular, the normative function performed by certain sentences and by certain speech acts has been investigated in depth. Still, the normative function performed by certain physical artifacts designed and built to regulate human behaviors has not yet been thoroughly investigated. We propose to call this specific type of artifacts with normative intent ‘deontic artifacts’. This article aims to investigate this normative phenomenon that is so widespread in (...) our daily reality, but so often forgotten by scholars of norms and normativity. (shrink)

According to the ‘fact-plus-value’ model of pathology propounded by K. W. M. Fulford, ‘disease’ is a value term that ought to reflect a ‘balance of values’ stemming from patients and doctors and other ‘stakeholders’ in medical nosology. In the present article I take issue with his linguistic-analytical arguments for why pathological status must be relative to such a kind of medico-ethical normativity. Fulford is right to point out that Boorse and other naturalists are compelled to utilize evaluative terminology when they (...) characterize the nature of diseases and biological dysfunctions. But the relevant ‘biofunctional judgements’ are no less factual and empirical for that. While it is indeed evaluative to say that biological dysfunctions involve failures to execute naturally selected functions, such judgments are not bound to entail anything about what is good or bad for us, and what should be treated or not. In the last part of the paper I ruminate briefly on the relationship between ‘biological evaluationism’, on my construal, and descriptions of ‘causal biology’. As I note in my conclusion, a strict bioevaluative concept of disease can be valid for every species on earth, and thus be of particular usefulness in general biological contexts. (shrink)

The category of anarchy is conventionally associated with the emergence of an autonomous discipline of International Relations. Recently, Donnelly has argued that anarchy has never been central to IR. His criticism targets not just concepts of anarchy but theories of anarchy and thereby expresses an anti-theory ethos tacitly accepted in the discipline. As a form of conceptual atomism, this ethos is hostile to structuralist and normative theories. This article aims to reinstate theoretical holism against conceptual atomism and to defend the (...) enduring relevance of theories of international anarchy for IR. This is done by revisiting two classic, structuralist accounts of international anarchy articulated in Kenneth Waltz’s Theory of International Politics and Hedley Bull’s Anarchical Society. It will be shown that both represent coherent theoretical ‘wholes’ which reveal a more complex relationship between anarchy and hierar... (shrink)

As a matter of fact, few, if any, theists have been expressivists about morality. This is probably because expressivism is thought to have unacceptable theological implications. That is, it is thought to imply (1) that God’s goodness depends on our desire-like states, (2) that God’s goodness is not a real property, (3) that it is not true that God is good, and (4) that God’s moral thoughts have no explanation. I argue that expressivism has no such implications and conclude that (...) expressivism is theologically acceptable. (shrink)

This paper proposes a new Separabilist account of thick concepts, called the Expansion View (or EV). According to EV, thick concepts are expanded contents of thin terms. An expanded content is, roughly, the semantic content of a predicate along with modifiers. Although EV is a form of Separabilism, it is distinct from the only kind of Separabilism discussed in the literature, and it has many features that Inseparabilists want from an account of thick concepts. EV can also give non-cognitivists a (...) novel escape from the Anti-Disentangling Argument. §I explains the approach of all previous Separabilists, and argues that there’s no reason for Separabilists to take this approach. §II explains EV. §III fends off objections. And §IV explains how non-cognitivist proponents of EV can escape the Anti-Disentangling Argument. (shrink)

Do psychopaths make moral judgments but lack motivation? Or are psychopaths’ judgments are not genuinely moral? Both sides of this debate seem to assume either externalist or internalist criteria for the presence of moral judgment. However, if moral judgment is a natural kind, we can arrive at a theory-neutral criterion for moral judgment. A leading naturalistic criterion suggests that psychopaths have an impaired capacity for moral judgment; the capacity is neither fully present nor fully absent. Psychopaths are therefore not counterexamples (...) to internalism. Nonetheless, internalism is empirically problematic because it is unable to explain psychopaths’ moral deficits. (shrink)

Why is someone enduringly prized as a philosopher? To answer this question, this historical case study examines the intersecting careers of John Rawls and R. M. Hare. It looks at their writings, a complex chain of disagreements, the argumentative dimension. The essay moreover explores the clash of differing temperaments. Finally, themes in addition to ratiocination and personality are factored in: the leanings of the institutions that control access to intellectual endeavor; the public square—politics widely conceived—into which the two men were (...) thrown; and the cultural rivalry between England and America after World War Two.

I discuss Ricoeur's intriguing account of the phenomenology of the will, which focuses on deciding rather than desiring as the experientially paradigmatic exercise of the will.

In a series of publications, Tamar Gendler has argued for a distinction between belief and what she calls ?alief?. Gendler's argument for the distinction is a serviceability argument: the distinction is indispensable for explaining a whole slew of phenomena, typically involving ?belief-behaviour mismatch?. After embedding Gendler's distinction in a dual-process model of moral cognition, I argue here that the distinction also suggests a possible (dis)solution of what is perhaps the organizing problem of contemporary moral psychology: the apparent tension between the (...) inherently motivational role of moral judgments and their manifestly objectivistic phenomenology. I argue that moral judgments come in two varieties, moral aliefs and moral beliefs, and it is only the former that are inherently motivating and only the latter that have an objectivistic phenomenology. This serves to both bolster the case for the alief/belief distinction and shed new light on otherwise well-trodden territory in metaethics. I start with an exposition of the moral-psychological problem (?1) and a discussion of Gendler's alief/belief distinction (?2). I then apply the latter to moral judgments in an attempt to dissolve the former (?3). I close with discussion of the upshot for our understanding of moral thought, moral motivation, and moral phenomenology (?4). (shrink)

In this paper, I address the what, the how, and the why of moral phenomenology. I consider first the question What is moral phenomenology?, secondly the question How to pursue moral phenomenology?, and thirdly the question Why pursue moral phenomenology? My treatment of these questions is preliminary and tentative, and is meant not so much to settle them as to point in their answers’ direction.

Supervenience is necessary co-variation between two sets of entities. In the good old days, supervenience was considered a useful philosophical tool with a wide range of applications in the philosophy of mind, metaethics, epistemology, and elsewhere. In recent years, however, supervenience has fallen out of favor, giving place to grounding, realization, and other, more metaphysically “meaty”, notions. The emerging consensus is that there are principled reasons for which explanatory theses cannot be captured in terms of supervenience, or as the slogan (...) goes: “Supervenience Is Nonexplanatory”. While SIN is widely endorsed, it is far from clear what it amounts to and why we should believe it. In this paper, I will distinguish various theses that could be meant by it, and will argue that none of them is both interesting and plausible: on some interpretations of ‘explanatory’, we have no reason to believe that supervenience is unexplanatory, while on other interpretations, supervenience is indeed unexplanatory, but widely accepted textbook cases of explanatory relations come out as unexplanatory, too. This result raises doubts as to whether there is any interesting sense in which SIN is true, and suggests that the contemporary consensus about supervenience is mistaken. (shrink)

Much moral skepticism stems from the charge that moral facts do not figure in causal explanations. However, philosophers committed to normative epistemological discourse (by which I mean our practice of evaluating beliefs as justified or unjustified, and so forth) are in no position to demand that normative facts serve such a role, since epistemic facts are causally impotent as well. I argue instead that pragmatic reasons can justify our continued participation in practices which, like morality and epistemology, do not serve (...) the function of causal explanation. Finally, I defend this pragmatic justification of morality and epistemology against a number of objections, including the objection that it confuses practical and theoretical justification. (shrink)

There is a fundamental inconsistency in Western society’s treatment of non-human animals on the one hand, and of human foetuses on the other. While most Western countries allow the butchering of animals and their use in experimentation, this must occur under carefully controlled conditions that are intended to minimize their pain and suffering as much as possible. At the same time, most Western countries permit various abortion methods without similar concerns for the developing fetus. The only criteria for deciding which (...) abortion method is used centre in the stage of the pregnancy, the size of the fetus, the health of the pregnant woman and the physician’s preference. This is out of step with the underlying ethos of animal cruelty legislation, cannot be justified ethically and should be rectified by adjusting abortion methods to the capacity of the fetus to experience nociception and/or pain.

This paper discusses in broad terms the metaphysical projects of Sydney Shoemaker’s Physical Realization . Specifically, I examine the effectiveness of Shoemaker’s novel “subset” account of realization for defusing the problem of mental causation, and compare the “subset” account with the standard “second-order” account. Finally, I discuss the physicalist status of the metaphysical worldview presented in Shoemaker’s important new contribution to philosophy of mind and metaphysics.

This is a review of Tim Henning's 'From a Rational Point of View' (Oxford 2019).

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence φ allows for cases in which one party utters φ and the other its negation, and neither party’s claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a (...) doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other’s claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the par- ties to reject each other’s claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. e existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well. (shrink)

There was a time when meta-ethical expressivism seemed to be the only game in town for meta-ethical non-representationalists. In recent years, though, meta-ethical inferentialism has emerged as a promising non-representationalist alternative. So far, however, inferentialists lack something that would really allow them to draw level with expressivists. This is an explanation for the distinctive difference between normative and descriptive vocabulary when it comes to disagreement—something expressivists can explain in terms of the difference between representational and desire-like states and which constitutes (...) one of the primary motivations for expressivism. This paper develops a novel and distinctive account for this difference on behalf of inferentialists, based on the different functions of these two vocabularies. Not only does this account help inferentialists, it also shows how non-representionalist accounts can capture the relevant disagreement phenomena without appealing to the sorts of desire-like states expressivists tend to appeal to.

ABSTRACTOne argument that has been suggested for conventionalism about personal identity is that it captures that certain disagreements about personal identity seem irresolvable, without being committed to the view that these disagreements are merely verbal. In this paper, I will take the considerations about disagreement used to motivate conventionalism seriously. However, I will use them to motivate a very different, novel, and as yet unexplored view about personal identity. This is the view that personal identity is a non-representational concept, the (...) nature of which isn’t to be accounted for in terms of what entity it represents, but its non-representational role. I highlight that we find structurally very similar concerns about disagreement in another philosophical debate, namely in meta-ethics. But, in meta-ethics, such sorts of considerations are, traditionally, thought to support one distinctive view: meta-ethical expressivism, a non-representational view about normative thought and discourse. This suggests that we should take a similar view seriously for personal identity. I also develop what such an unfamiliar view might look like, using expressivism as a template. On this view, judgements about personal identity are plans that regulate who to hold accountable. (shrink)

ABSTRACT It has been frequently observed in the literature that assertions of plain sentences containing predicates like fun and frightening give rise to an acquaintance inference: they imply that the speaker has first-hand knowledge of the item under consideration. The goal of this paper is to develop and defend a broadly expressivist explanation of this phenomenon: acquaintance inferences arise because plain sentences containing subjective predicates are designed to express distinguished kinds of attitudes that differ from beliefs in that they can (...) only be acquired by undergoing certain experiences. Its guiding hypothesis is that natural language predicate expressions lexically specify what it takes for their use to be properly ‘grounded’ in a speaker's state of mind: what state of mind a speaker must be in for a predication to be in accordance with the norms governing assertion. The resulting framework accounts for a range of data surrounding the acquaintance inference as well as for striking parallels between the evidential requirements on subjective predicate uses and the kind of considerations that fuel motivational internalism about the language of morals. A discussion of how the story can be implemented compositionally and of how it compares with other proposals currently on the market is provided. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

In disputes about conceptual analysis, each side typically appeals to pre-theoretical 'intuitions' about particular cases. Recently, many naturalistically oriented philosophers have suggested that these appeals should be understood as empirical hypotheses about what people would say when presented with descriptions of situations, and have consequently conducted surveys on non-specialists. I argue that this philosophical research programme, a key branch of what is known as 'experimental philosophy', rests on mistaken assumptions about the relation between people's concepts and their linguistic behaviour. The (...) conceptual claims that philosophers make imply predictions about the folk's responses only under certain demanding, counterfactual conditions. Because of the nature of these conditions, the claims cannot be tested with methods of positivist social science. We are, however, entitled to appeal to intuitions about folk concepts in virtue of possessing implicit normative knowledge acquired through reflective participation in everyday linguistic practices.

Many an adult Ugandan probably employs the language of morals more or less unconsciously but frequently in everyday conversation. But, how do some Ugandans use language when they say of some things in a moral sense that it is good or right, because is not a matter related to corruption, bad or wrong, since it is a corruption-related issue? The author endeavours to analyse a given language that many Ugandans use when confronted with situations and/or facts of corruption and when (...) they make moral judgements about these situations and facts from a metaethical perspective. He confirms that what he terms a language of corruption exists in Uganda and is employed to condone or approve corrupt acts in certain circumstances. That language of corruption, the author recommends, should not be regarded as amoral, but as moral in character and it must be addressed as such. (shrink)

In this paper I examine which is the most appropriate moral theory for dealing with disaster bioethics contexts. It is pointed out that, contrary to what is usually believed, moral theories of right action cannot actually guide us in such difficult situations. Instead, it is claimed that a virtue ethics theory of an Aristotelian version, which gives emphasis not only on the virtuous person but also on the relevant developmental process of becoming virtuous, can provide us with the right theoretical (...) framework for coping with the problems which the victims of such disastrous situations face.

Technological enthusiasm is a value that can influence engineering, shape technologies and subsequently transform human lifestyles. Despite its significant role, up until now, there has been little research done on this value. The dominant idea is that this value is commendable. However, based on consequentialism, a recently proposed idea describes TE as neither morally commendable nor reprehensible. In this paper, three arguments are presented against this recent idea, and a new idea is introduced, which challenges not only commendation for TE (...) but also neutrality of TE. Further, it is shown that a virtue ethics approach can be adopted to evaluate the moral role of TE. In the approach, TE can be considered a character trait or a virtue/vice. Then, three arguments are proposed to indicate that TE is not a virtue but a vice. This paper illustrates some advantages of virtue ethics in ethical evaluation of a problem in which consequentialism or utilitarianism is not effective. (shrink)

If the logic of belief changes is extended to cover belief states which contain both factual and normative beliefs, it is easily shown that a change of a factual belief (an 'Is') in a mixed belief state can imply a change of a normative belief (an 'Ought') in the same state. With regard to Hume's so-called 'Is-Ought problem', this means that one has to distinguish its statics from its dynamics. When this is done, it becomes clear that changes of factual (...) beliefs can, for rational reasons, have far-reaching normative consequences. Similarly, a change of a factual belief can imply a change of a value belief. (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.

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)

In "Milk, Honey, and the Good Life on Moral Twin Earth", David Copp explores some ways in which a defender of synthetic moral naturalism might attempt to get around our Moral Twin Earth argument. Copp nicely brings out the force of our argument, not only through his exposition of it, but through his attempt to defeat it, since his efforts, we think, only help to make manifest the deep difficulties the Moral Twin Earth argument poses for the synthetic moral naturalist.
