Simon Blackburn’s supervenience argument—focusing on the mysterious “ban on mixed worlds”—is still subject to a variety of conflicting interpretations. In this paper, I hope to provide a defense of the argument that clarifies both the argument and the objections it must overcome. Many of the extant objections, I will argue, fail to engage the argument in its true form. And to counter the more compelling objections, it will be necessary to bring in additional argumentation that Blackburn himself does not clearly (...) provide. One important upshot of this discussion is that moral realism is not the only target of the argument: it raises trouble for a variety of metaethical views wed to realist-friendly construals of moral evaluation. Rightly understood, this argument not only survives the prominent responses, but turns out to be more powerful than his critics and Blackburn himself have recognized. (shrink)

In the 1970s and 1980s, Simon Blackburn published a number of much-discussed works in which he argued that the supervenience of the moral on the natural generates a serious problem for moral realism, a problem which his own brand of moral projectivism can avoid. As we will see below, Blackburn construed moral supervenience in terms of what is known as weak supervenience. Partly in response to Blackburn, a number of philosophers have argued that weak supervenience is too weak to capture (...) the intuitive sense in which the moral supervenes on the natural. Instead, it is argued, we should opt for strong supervenience, and, further, that strong supervenience completely disables Blackburn's argument against moral realism. This idea – that strong supervenience undermines Blackburn's argument – is very common in recent metaethics, and the purpose of the present paper is to develop a challenge to this near-orthodoxy.

My main goal in this article is methodological: I want to spell out how a Kantian perspective could accommodate current empirical work on cognition, and in particular on emotion. Having chosen John McDowell as a guide, I try to characterize his view of moral experience and underline its Kantian traits. I start by identifying the conception of freedom as exemplified in the rational wolf thought experiment in Two Forms of Naturalism as the main Kantian trait. I then go through the (...) characterization of two other crucial aspects of our moral experience – reasons and value. I suggest that McDowell’s approach to moral experience, although not itself strictly Kantian in all of its details, is an instance of a transformative view of rationality, as defended by Matthew Boyle and that such transformative view is the key to accommodate empirical research on cognition within a Kantian perspective.

Ethical rationalism has recently dominated the philosophical landscape, but sentimentalist forms of normative ethics (such as the ethics of caring) and of metaethics (such as Blackburn's projectivism and various ideal–observer and response–dependent views) have also been prominent. But none of this has been systematic in the manner of Hume and Hutcheson. Hume based both ethics and metaethics in his notion of sympathy, but the project sketched here focuses rather on the (related) notion of empathy. I argue that empathy is essential (...) to the development of morally required caring about others and also to deontological limits or restrictions on self–concern and other–concern. But empathy also plays a grounding role in moral judgement. Moral approval and disapproval can be non–circularly understood as empathic reflections of the concern or lack of concern that agents show towards other people; and moral utterances can plausibly be seen not as projections, expressions, or descriptions of sentiment but as “objective” and “non–relative” judgements whose reference and content are fixed by sentiments of approval and disapproval.

In this paper we defend the view that the ordinary notions of cause and effect have a direct and essential connection with our ability to intervene in the world as agents.1 This is a well known but rather unpopular philosophical approach to causation, often called the manipulability theory. In the interests of brevity and accuracy, we prefer to call it the agency theory.2 Thus the central thesis of an agency account of causation is something like this: an event A is (...) a cause of a distinct event B just in case bringing about the occurrence of A would be an effective means by which a free agent could bring about the occurrence of B. In our view the unpopularity of the agency approach to causation may be traced to two factors. The first is a failure to appreciate certain distinctive advantages that this approach has over its various rivals. We have drawn attention to some of these advantages elsewhere, and we summarize below. However, the second and more important factor is the influence of a number of stock objections, objections that seem to have persuaded many philosophers that agency accounts face insuperable obstacles. In this paper we want to show that these objections have been vastly overrated. There are four main objections. (shrink)

Phenomena such as our “understanding in a flash” and our immediate knowledge of the meaning of our own utterances seem to point to problems that call for philosophical explanation. Even though the meaning of an utterance appears to depend on where and when we use it, on what we use it for and on what we expect in response, we do not examine such circumstances when asked what we mean. Instead we simply say what we mean. Similarly, our having grasped (...) a rule is something shown by how we perform certain tasks and respond to certain requests. But we frequently declare that we have indeed grasped a rule without paying any attention to those overt performances and, despite this, we are normally correct. These facts seem puzzling and impel us towards a certain philosophical picture of meaning and understanding. This picture identifies the meaning of a subject’s utterances, and his understanding of the rules that he follows, with some kind of structure of which he has immediate knowledge. By virtue of their connection with these private, meaning-constituting phenomena, the public manifestations of meaning and understanding are invaluable as clues to the meaning of an utterance or a subject’s understanding of a rule. But the latter are, nevertheless, ultimately fixed by the inner structures to which only the subject in question has immediate access and upon which he or she therefore has authority. This picture prompts a host of perplexing questions. “What are these immediately-knowable structures?” “What does it mean to say that we have immediate acquaintance with them?” “How are these private structures connected with those public performances?” These questions are notoriously difficult to answer.

Many claims about conceptual matters are often represented as, or inferred from, claims about the meaning, reference, or mastery, of words. But sometimes this has led to treating conceptual analysis as though it were nothing but linguistic analysis. We canvass the most promising justifications for moving from linguistic premises to substantive conclusions. We show that these justifications fail and argue against current practice (in metaethics and elsewhere), which confuses an investigation of a word’s meaning, reference, or competence conditions with an (...) analysis of some concept or property associated with that word.

In this paper I continue an enterprise begun in earlier work in which I attempt to naturalize into a western philosophical context concepts that derive from the practice of Buddhist meditation. In particular I shall try to make use of the notion of samādhi and vipassanā or insight. I should stress that I make no attempt at a scholarly explication of these terms but try rather to establish a use for them through reflection on experience, and by making a connection (...) with concerns from aesthetics about expression and intentionality: I do so as a moral philosopher seeking to retrieve the Greek virtues of continence and temperance, which I have tried to relate to stages in the emergence of what I call an ‘ethical sensibility’, so that temperance, for instance, is the natural state of one in whom such a sensibility is flourishing. But I see the development of that sensibility as the concentration or gathering of a person's energies into its structure, into the sustaining of the thought or perception upon which action or non-action depends, as well as into the sustaining of action itself. In talking of ‘energy’ here I am trying to develop an idea of Simone Weil's in which she refers to ‘the energy available for action’. (shrink)

There seem to be topics on which people can disagree without fault. For example, you and I might disagree on whether Picasso was a better artist than Matisse, without either of us being at fault. Is this a genuine possibility or just apparent? In this paper I pursue two aims: I want to provide a systematic map of available responses to this question. Simultaneously, I want to assess these responses. I start by introducing and defining the notion of a faultless (...) disagreement. Then I present a simple argument to the conclusion that faultless disagreement is not possible. Those who accept the argument have to explain away apparent cases of faultless disagreement. Those who want to maintain the possibility of faultless disagreement must deny one of the argument's premisses. The position I want to promote belongs to the latter category and is a form of genuine relativism. (shrink)

What is a concept? Philosophers have given many different answers to this question, reflecting a wide variety of approaches to the study of mind and language. Nonetheless, at the most general level, there are two dominant frameworks in contemporary philosophy. One proposes that concepts are mental representations, while the other proposes that they are abstract objects. This paper looks at the differences between these two approaches, the prospects for combining them, and the issues that are involved in the dispute. We (...) argue that powerful motivations have been offered in support of both frameworks. This suggests the possibility of combining the two. Unlike Frege, we hold that the resulting position is perfectly coherent and well worth considering. Nonetheless, we argue that it should be rejected along with the view that concepts are abstract objects. (shrink)

This paper discusses and criticizes Segal’s 1989 argument against singular object-dependent thoughts. His argument aims at showing that object-dependent thoughts are explanatorily redundant. My criticism of Segal’s argument has two parts. First, I appeal to common anti-individualist arguments to the effect that Segal’s type of argument only succeeds in establishing that object-dependent thoughts are explanatorily redundant for those aspects of subjects’ behaviour that do not require reference to external objects. Secondly, Segal’s view on singular thoughts is at odds with his (...) view on the semantics of proper names, which favours the singularity and object-dependency of the truth-conditions of sentences in which they occur. In particular, his views are at odds with a position he holds, that truth-conditional semantics can adequately account for all aspects of speakers’ linguistic competence in the use of proper names.

This paper argues for contextualism about predicates of personal taste and evaluative predicates in general, and offers a proposal of how apparently resilient disagreements are to be explained. The present proposal is complementary to others that have been made in the recent literature. Several authors, for instance (López de Sa, 2008; Sundell, 2011; Huvenes, 2012; Marques and García-Carpintero, 2014; Marques, 2014a), have recently defended semantic contextualism for those kinds of predicates from the accusation that it faces the problem of lost (...) disagreement. These authors have proposed that a proper account of the resilient disagreement in the cases studied is to be achieved by an appeal to pragmatic processes, and to conflicting non-doxastic attitudes. It is argued here that the existing contextualist solutions are incomplete as they stand, and are subject to objections because of this. A supplementation of contextualism is offered, together with an explanation of why failed presuppositions of commonality (López de Sa), disputes over the appropriateness of a contextually salient standard (Sundell), and differences in non-doxastic attitudes (Sundell, Huvenes, Marques, and García-Carpintero) give rise to conflicts. This paper claims that conflicts of attitudes are the reason why people still have impressions of disagreement in spite of failed commonality presuppositions, that those conflicts drive metalinguistic disputes over the selection of appropriate standards, and hence conflicting non-doxastic attitudes demand an explanation that is independent of those context dependent pragmatic processes. The paper further argues that the missing explanation is 2-fold: first, disagreement prevails where the properties expressed by taste and value predicates are response-dependent properties, and, secondly, it prevails where those response-dependent properties are involved in evolved systems of coordination that respond to evolutionarily recurrent situations.

Pluralism about truth is the view that there is more than one way for a proposition to be true. When taken to imply that there is more than one concept and property of truth, this position faces a number of troubling objections. I argue that we can overcome these objections, and yet retain pluralism's key insight, by taking truth to be a multiply realizable property of propositions.

The paper advances a Humean metaethical analysis of "intrinsic value" - a notion fundamental in moral philosophy in general and particularly so in environmental ethics. The analysis reduces an object's moral properties (e.g., its value) to the empirical relations between the object's natural properties and people's psychological dispositions to respond to them. Moral properties turn out to be both objective and subjective, but in ways compatible with, and complementary to, each other. Next, the paper investigates whether the Humean analysis can (...) support non-anthropocentric environmental ethical theories, which attribute intrinsic value to nonhuman natural entities. It argues that one of the most useful resources from Hume for non-anthropocentrism is his account of justice as an artificial virtue, which is a plausible model for the internalization of various environmentally friendly conventions and the creation of environmental values. Finally, the paper concludes that any Humean account of intrinsic value is empiricist all the way down. Moral questions about what things are intrinsically valuable, and to what extent they are so, are ultimately empirical questions about complex psychological capacities and dispositions of human beings, which cannot be single-handedly answered by philosophers a priori; and that ethics is more appropriately seen as an interdisciplinary investigation, requiring collaboration among the various psychological and social sciences, human biological and neurological sciences, and history and philosophy.

The paper explores the consequences of adopting a moral error theory targeted at the notion of reasonable convergence. I examine the prospects of two ways of combining acceptance of such a theory with continued acceptance of moral judgements in some form. On the first model, moral judgements are accepted as a pragmatically intelligible fiction. On the second model, moral judgements are made relative to a framework of assumptions with no claim to reasonable convergence on their behalf. I argue that the (...) latter model shows greater promise for an error theorist whose commitment to moral thought is initially serious. (shrink)

Darwin’s treatment of morality in The Descent of Man has generated a wide variety of responses among moral philosophers. Among these is the dismissal of evolution as irrelevant to ethics by Darwin’s contemporary Henry Sidgwick; the last, and arguably the greatest, of the Nineteenth Century British Utilitarians. This paper offers a re-examination of Sidgwick’s response to evolutionary considerations as irrelevant to ethics and the absence of any engagement with Darwin’s work in Sidgwick’s main ethical treatise, The Methods of Ethics . (...) This assessment of Sidgwick’s response to Darwin’s work is shown to have significance for a number of ongoing controversies in contemporary metaethics. (shrink)

This essay presents a new theory of statutory application that is superior to two competitors. One of the competitors claims that statutory directives apply to act-tokens fitting the legislature's intention. The other holds that statutes apply to act-tokens that are of the genuine kinds named by the classifying words. These theories solve certain problems badly or not at all, respectively: (1) accounting for the capacity of statutes for epistemic guidance; and (2) avoiding literalism. Both do a limited job of accounting (...) for the rationality of statutory promulgation. The theory developed here, social salience theory, does better on all counts. According to social salience theory, the default position is that statutes apply to act-tokens that are socially salient, given the linguistic and social contexts. The departure from that position is also social, produced by conventions to defer to experts on the statute's applications to particular cases. (shrink)

Charles Peirce's diagrammatic logic — the Existential Graphs — is presented as a tool for illuminating how we know necessity, in answer to Benacerraf's famous challenge that most ‘semantics for mathematics’ do not ‘fit an acceptable epistemology’. It is suggested that necessary reasoning is in essence a recognition that a certain structure has the particular structure that it has. This means that, contra Hume and his contemporary heirs, necessity is observable. One just needs to pay attention, not merely to individual (...) things but to how those things are related in larger structures, certain aspects of which relations force certain other aspects to be a certain way.

The Language of Thought Hypothesis is often taken to have the fatal flaw that it generates an explanatory regress. The language of thought is invoked to explain certain features of natural language (e.g., that it is learned, understood, and is meaningful), but, according to the regress argument, the language of thought itself has these same features and hence no explanatory progress has been made. We argue that such arguments rely on the tacit assumption that the entire motivation for the language (...) of thought consists in explaining the explanandum that allegedly generates the regress. But this tacit assumption is simply false. The Language of Thought Hypothesis is a cogent view and one with considerable explanatory advantages. (shrink)

In order to understand a sentence, one must know the relevant semantic rules. Those rules are not learned in a vacuum; they are given to one through one's senses. As a result, knowledge of semantic rules sometimes comes bundled with semantically irrelevant, but cognitively non-innocuous, knowledge of the circumstances in which those rules were learned. Thus, one must work through non-semantic information in order to know what is literally meant by a given sentence-token. A consequence is that one's knowledge of (...) what is literally meant by a given sentence-token is sometimes embedded in non-semantic knowledge, resulting in a cleavage between what that sentence-token literally means and what the auditor in question takes it to mean. Such deviations obviously have nothing to do with the principles put forth by Grice, since those principles only concern sentence-tokens that have already been understood---since, to put it another way, those principles only concern post-semantic implicature. The just-described deviations are appropriately described as being due to "pre-semantic implicature." Given the phenomenon of pre-semantic implicature, it is easily shown that Russell's Theory of Descriptions, if taken as a theory of literal meaning, is false. In the present volume, these rather elementary principles are entirely ignored, and all of the articles in it are sterile repetitions of the points made by Russell and Strawson. The blinkered approach to language embodied in this volume must be reconsidered in light of psychological principles relating to language-acquisition and language-use. Unfortunately, analytic philosophers shy away from such topics, as is made clear by the papers in this grim volume. (shrink)

Several prominent philosophers believe that moral facts are facts about what reasons we have, and that this entails that moral judgments are necessarily and inherently motivating. According to this argument, if morality cannot move us, then it is hard to understand how it could be sensibly regarded as action-guiding or normative. That is, they endorse a traditional argument for motivational judgment internalism based on moral rationalism. This paper criticizes this argument, and argues instead that there is no necessary or conceptual (...) connection between moral facts and motivation. First, I formulate MJI as the thesis that moral judgments are necessarily and inherently motivating, and introduced several refinements designed to accommodate some plausible exceptions to the initial formulation. I then introduce MR as the thesis that moral facts are identical with or analyzable in terms of facts about requirements of reason. MR is ambiguous between an interpretation that analyzes moral requirements in terms of motivating reasons, and is also subject to various possible refinements, and an interpretation that proceeds in terms of justifying reasons. Finally, I argue that neither interpretation entails any interesting or plausible formulation of MJI. If the argument of this paper are sound, then there is no important connection between moral rationalism and motivational internalism. (shrink)

When speakers utter conflicting moral sentences, it seems clear that they disagree. It has often been suggested that the fact that the speakers disagree gives us evidence for a claim about the semantics of the sentences they are uttering. Specifically, it has been suggested that the existence of the disagreement gives us reason to infer that there must be an incompatibility between the contents of these sentences. This inference then plays a key role in a now-standard argument against certain theories (...) in moral semantics. In this paper, we introduce new evidence that bears on this debate. We show that there are moral conflict cases in which people are inclined to say both that the two speakers disagree and that it is not the case at least one of them must be saying something incorrect. We then explore how we might understand such disagreements. As a proof of concept, we sketch an account of the concept of disagreement and an independently motivated theory of moral semantics which, together, explain the possibility of such cases. (shrink)

Quasi-realism prominently figures in the expressivist research program. However, many complain that it has become increasingly unclear what exactly quasi-realism involves. This paper offers clarification. It argues that we need to distinguish two distinctive views that might be and have been pursued under the label “quasi-realism”: conciliatory expressivism and quasi-realism properly so-called. Of these, only conciliatory expressivism is a genuinely meta-ethical project, while quasi-realism is a first-order normative view. This paper demonstrates the fruitfulness of these clarifications by using them to (...) address Terence Cuneo’s recent challenge that quasi-realist expressivists lack the resources to plausibly accommodate certain sorts of data points.

Davidson has attempted to offer his own solution to the problem of self-knowledge, but there has been no consensus between his commentators on what this solution is. Many have claimed that Davidson’s account stems from his remarks on disquotational specifications of self-ascriptions of meaning and mental content, the account which I will call the “Disquotational Explanation”. It has also been claimed that Davidson’s account rather rests on his version of content externalism, which I will call the “Externalist Explanation”. I will (...) argue that not only are these explanations of self-knowledge implausible, but Davidson himself has already rejected them. Thus, neither can be attributed to Davidson as his suggested account of self-knowledge. I will then introduce and support what I take to be Davidson’s official and independent account of self-knowledge, that is, his “Transcendental Explanation”. I will defend this view against certain potential objections and finally against the objections made by William Child. (shrink)

Metaethical realists believe that moral facts exist, but they disagree among themselves about whether moral facts have ontological import. Robust realists think that they do. Quietist realists deny this. I argue that quietist realism faces a new objection; viz., the moral determination objection. This is the objection that general moral facts (or moral principles) must determine specific moral facts (or which actions in the world are right and wrong) but that general moral facts cannot do this if they lack ontological (...) import. I also argue that some robust realists can answer the moral determination objection. This gives these robust realists an edge over quietist realism. (shrink)

A critical review of Paul Boghossian's Fear of Knowledge. I argue that the central argument against epistemic relativism fails and that even if the arguments of Fear of Knowledge worked perfectly on their own terms, Fear of Knowledge would fail to persuade the relativistically inclined.

Facts about the evolutionary origins of morality may have some kind of undermining effect on morality, yet the arguments that advocate this view are varied not only in their strategies but in their conclusions. The most promising such argument is modest: it attempts to shift the burden of proof in the service of an epistemological conclusion. This paper principally focuses on two other debunking arguments. First, I outline the prospects of trying to establish an error theory on genealogical grounds. Second, (...) I discuss how a debunking strategy can work even under the assumption that noncognitivism is true. (shrink)

Lewis has argued that quasi-realism is fictionalism. Blackburn denies this, offering reasons which rely on a descriptive reading of quasi-realism. This note offers a different, more general argument against Lewis's claim, available to prescriptive as well as descriptive quasi-realists.

The purpose of this paper is to examine some contentions advanced by B. A. O. Williams in his books Descartes: The Project of Pure Enquiry and Ethics and the Limits of Philosophy . In particular I shall be concerned with the claims he makes about the nature of ethics—namely that it cannot be ‘objective’ or ‘realistic’ and that we may not hope for rational convergence in ethical judgments. My claims will be that Williams's case on these matters is importantly unclear (...) and incomplete and that we lack cogent reasons to accept the conclusions he offers us. But a good deal of scene-setting is necessary before we can pose the questions I wish to address. (shrink)

Ordinary normative discourse includes talk about the reasons for action we had in the past but only came to discover in hindsight. In some cases, we come to discover these reasons not because new information has come to light, but because our values have changed. Contemporary metaethical views, namely Street's Humean constructivism and Blackburn's and Gibbard's quasi-realism, have some difficulty accounting for these reasons and the claims we make about them. This difficulty hinges on the diachronic complexity of these reasons (...) and claims. It cannot be the case that these reasons were constructed by the perspective we had in the past before our values changed. If there were no extant reasons in the past, then it would seem that our claims about them in the present cannot be true. Quasi-realists can account for the way in which reason claims purport to be true by appealing to a deflationary sense of truth and so can remain agnostic on the actual existence of these reasons. Nevertheless, Street argues that t.. (shrink)

The idea that there can be cases of faultless disagreement, cases of disagreement in which neither party is making a mistake, is frequently discussed in connection with relativist views in philosophy of language. My goal is to argue that we can make sense of faultless disagreement without being committed to any form of relativism if we recognise that disagreement sometimes involves attitudes other than belief, such as desires or preferences. Furthermore, this way of making sense of faultless disagreement allows us (...) to avoid some of the problems that have been raised in connection with relativist accounts of faultless disagreement.

Predicates of taste, such as ‘fun’ and ‘tasty’, have received considerable attention in recent debates between contextualists and relativists, with considerations involving disagreement playing a central role. Considerations involving disagreement have been taken to present a problem for contextualist treatments of predicates of taste. My goal is to argue that considerations involving disagreement do not undermine contextualism. To the extent that relativism was supposed to be motivated by contextualists being unable to deal with disagreement, this motivation is lacking. The argument (...) against contextualism rests on a too simple and narrow conception of disagreement that turns out to be problematic once we consider a wider range of cases. If we reject the assumptions about disagreement that the argument rests on, it no longer poses a threat to contextualism. (shrink)

A widespread concern within philosophy has been, and continues to be, to determine which domains of discourse address real, robust, not‐merely‐deflationary facts, and which do not. But a threat to the legitimacy of this concern is the extreme lack of consensus amongst philosophers on the question of how to tell whether or not a given domain is oriented towards ‘robust reality’. The present paper criticizes Kit Fine’s attempt to settle that question. This discussion is followed by some considerations suggesting that (...) there is no good answer to it, that the notion of ‘robust reality’ is defective and ought to be abandoned. (shrink)

I want to promote what I shall call ‘the identity theory of truth’. I suggest that other accounts put forward as theories of truth are genuine rivals to it, but are unacceptable. A certain conception of thinkables belongs with the identity theory’s conception of truth. I introduce these conceptions in Part I, by reference to John McDowell’s Mind and World; and I show why they have a place in an identity theory, which I introduce by reference to Frege. In Part (...) II, I elaborate on the conception of thinkables, with a view to demonstrating that the identity theory’s conception of truth is defensible. Part III is concerned with the theory’s relation to some recent work on the concept of truth: I hope to show that the identity theorist not only has a defensible conception of truth, but also, in the present state of play, has appropriate ambitions.

Kant claims that the judgement of taste, the judgement that some particular is beautiful, exhibits two ‘peculiarities’. First: [t]he judgement of taste determines its object in respect of delight with a claim to the agreement of every one , just as if it were objective.

The aim of this paper is to discover whether or not a solitary individual, a human being isolated from birth, could become a rule-follower. The argumentation against this possibility rests on the claim that such an isolate could not become aware of a normative standard, with which her actions could agree or disagree. As a consequence, theorists impressed by this argumentation adopt a view on which the normativity of rules arises from corrective practices in which agents engage in a community. (...) However, it has been suggested that an isolated individual could engage in such a practice by herself. Three prospective examples of such cases are considered, and the possibility of solitary rule-following is vindicated. Furthermore, the nature of the goals at which rule-following practices generally aim is clarified. (shrink)

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver (...) is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false. (shrink)
