Nous comparons les notions d’usage et de signification chez Ludwig Wittgenstein et Martin Heidegger. Contrairement à Jocelyn Benoist, nous pensons que l’analogie entre Wittgenstein et Heidegger n’est pas superficielle. La métaphysique de Heidegger explicite certaines présuppositions implicites de la seconde philosophie de Wittgenstein. Le pragmatisme naturaliste de Wittgenstein peut être théorisé. Notamment la notion wittgensteinienne d’usage, ou de jeu de langage, peut être comprise comme une pratique à la fois naturelle et normative régie par des règles. -/- Wittgenstein’s notions of (...) use and meaning are compared with the corresponding Heidegger’s ones. Unlike Jocelyn Benoist, we suggest that the analogy between Wittgenstein and Heidegger is not superficial. Heidegger’s metaphysics makes explicit some of the implicit presuppositions of Wittgenstein’s philosophy. Wittgenstein’s naturalistic pragmatism can be theorized. In particular, Wittgenstein’s notion of use, or language game, can be understood as both natural and normative rule- governing practice. (shrink)

Phenomenal consciousness appears to be particularly normatively significant. For this reason, sentience-based conceptions of ethics are widespread. In the field of animal ethics, knowing which animals are sentient appears to be essential to decide the moral status of these animals. I argue that, given that materialism is true of the mind, phenomenal consciousness is probably not particularly normatively significant. We should face up to this probable insignificance of phenomenal consciousness and move towards an ethic without sentience.

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist theories currently on (...) the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

We propose a new approach to the study of introspection. Instead of asking what form introspection actually takes in humans or other animals, we ask what forms it could take, in natural or artificial minds. What are the dimensions along which forms of introspection could vary? This is a relatively unexplored question, but it is one that has the potential to open new avenues of study and reveal new connections between existing ones. It may, for example, focus attention on possible (...) forms of introspection radically different from the human one and help to integrate competing theories of human introspection in a non-adversarial manner. We introduce and motivate the project, provide a preliminary mapping of the space of possible forms of introspection, and sketch a programme for interdisciplinary research on the topic. (shrink)

Animal ethicists have been debating the morality of speciesism for over forty years. Despite rather persuasive arguments against this form of discrimination, many philosophers continue to assign humans a higher moral status than nonhuman animals. The primary source of evidence for this position is our intuition that humans’ interests matter more than the similar interests of other animals. And it must be acknowledged that this intuition is both powerful and widespread. But should we trust it for all that? The present (...) paper defends a negative answer to that question, based on a debunking argument. The intuitive belief that humans matter more than other animals is unjustified because it results from an epistemically defective process. It is largely shaped by tribalism, our tendency to favor ingroup members as opposed to outgroup members. And this influence is distortive for two reasons. First, tribalism evolved for reasons unrelated to moral truths; hence, it would at best produce true moral beliefs accidentally. Second, tribalism generates a vast quantity of false moral beliefs, starting with racist beliefs. Once this intuition is discarded, little evidence remains that speciesism is morally acceptable.

Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism. (shrink)

Illusionism about consciousness is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Embracing illusionism presents the theoretical advantage that one does not need to explain how consciousness arises from purely physical brains anymore, but only to explain why consciousness seems to exist while it does not. As Keith Frankish puts it, illusionism replaces the “hard problem of consciousness” with the “illusion problem.” However, a satisfying version of illusionism has to explain not only why the illusion (...) of consciousness arises, but also why it arises with its particular strength: Notably, why we are so deeply reluctant to recognize the illusory nature of consciousness. Explaining our strong intuitive resistance to illusionism means solving what I call the “illusion meta-problem,” which I think is a part of the illusion problem. In this paper, I argue that current versions of illusionism are unable to solve the illusion meta-problem. I focus on two of the most promising recent illusionist theories of consciousness, and I show why they fail to explain the peculiar reluctance we encounter whenever we try to accept that consciousness is an illusion.

Common sense has it that animals matter considerably less than humans; the welfare and suffering of a cow, a chicken or a fish are important but not as much as the welfare and suffering of a human being. Most animal ethicists reject this “speciesist” view as mere prejudice. In their opinion, there is no difference between humans and other animals that could justify such unequal consideration. In the opposite camp, advocates of speciesism have long tried to identify a difference that (...) would fit the bill, but they have consistently seemed to fail. In light of this, some naturally began to appeal to Moorean arguments: the case against speciesism must be flawed somehow, these philosophers maintain, because speciesism is supported by a strong and widespread intuition. This chapter draws on recent findings in social psychology to criticize this defence of speciesism. It argues that the strong and widespread intuition that humans count more than animals is epistemically defective because it is causally shaped by a pair of irrelevant influences: cognitive dissonance and tribalism. Accordingly, it is no suitable basis for a Moorean argument. (shrink)

Theoreticians that defend a form of realism regarding natural kinds minimally entertain the belief that the world features divisions into kinds and that the natural kind concept is a useful tool for philosophy of science. The objective of this paper is to challenge these assumptions. First, we challenge realism toward natural kinds by showing that the main arguments for their existence, which rely on the epistemic success of natural kinds, are unsatisfactory. Second, we show that, whether they exist or not, (...) natural kinds are expendable when it comes to describing and analyzing scientific explanations accurately. (shrink)

The prevalent view in animal ethics is that speciesism is wrong: we should weigh the interests of humans and non-humans equally. Shelly Kagan has recently questioned this claim, defending speciesism against Peter Singer’s seminal argument based on the principle of equal consideration of interests. This critique is most charitably construed as a dilemma. The principle of equal consideration can be interpreted in either of two ways. While it faces counterexamples on the first reading, it makes Singer’s argument question-begging on the (...) second. In response, Singer has grasped the first horn of this dilemma and tried to accommodate Kagan’s apparent counterexamples. In my opinion, this attempt is unpersuasive: the principle of equal consideration is inconsistent with common-sense intuitions on Kagan’s cases. Worse, Singer’s argument begs the question anyway. It therefore faces two serious objections. This is not to say that there is nothing wrong with speciesism, however. In the second half of the paper, I propose another, better argument against speciesism, which I argue is immune to both objections. According to this other argument, speciesism is wrong because it involves discriminating on the basis of a merely biological property. (shrink)

Illusionists about phenomenal consciousness claim that phenomenal consciousness does not exist but merely seems to exist. At the same time, it is quite intuitive for there to be some kind of link between phenomenality and value. For example, some situations seem good or bad in virtue of the conscious experiences they feature. Illusionist views of phenomenal consciousness then face what I call the normative challenge. They have to say where they stand regarding the idea that there is a link between (...) phenomenality and value. If they accept that there is such a link, they might be committed to revisionary normative consequences (and some of them may prove to be uncomfortable). If they deny that there is such link, they might avoid revisionary normative consequences (without being guaranteed against them) but then they have to give reasons to deny that such link obtains, which is not a trivial task. The existence of the normative challenge does not show that illusionism is false, but it shows that illusionism might have important consequences in the normative domain, which have to be clarified.

Many people believe that human interests matter much more than the like interests of non-human animals, and this “speciesist belief” plays a crucial role in the philosophical debate over the moral status of animals. In this paper, I develop a debunking argument against it. My contention is that this belief is unjustified because it is largely due to an off-track process: our attempt to reduce the cognitive dissonance generated by the “meat paradox”. Most meat-eaters believe that it is wrong to (...) harm animals unnecessarily, yet they routinely and deliberately behave in ways that cause great unnecessary suffering to animals. As recent research suggests, this practical inconsistency puts them in an unpleasant state of dissonance, which they try to escape by resolving the paradox. And they do so in part by adopting the speciesist belief—if animal suffering matters much less than human suffering, then harming animals cannot be so wrong after all. Since this belief-forming process does not track moral truth, I conclude that we are not justified in believing that human interests matter more than the similar interests of non-humans. (shrink)

According to philosophical orthodoxy, the parties to moral or legal disputes genuinely disagree only if their uses of key normative terms in the dispute express the same meaning. Recently, however, this orthodoxy has been challenged. According to an influential alternative view, genuine moral and legal disagreements should be understood as metalinguistic negotiations over which meaning a given term should have. In this paper, we argue that the shared meaning view is motivated by much deeper considerations than its recent critics recognize, (...) and that much would be lost in opting for the explanation of normative disputes as metalinguistic negotiations.

Premier ouvrage de l’histoire de la philosophie à être totalement consacré au concept d’entéléchie, il ne s’agira pas de proposer un essai historique allant de la mise en place de cette notion chez Aristote jusqu’à la conception biologique développée par Hans Driesch. Inscrit dans un projet plus global de compréhension du temps aristotélicien, c’est à une véritable refondation métaphysique du concept que ce travail nous convie. Si Kant, à l’ultime fin de sa première critique, avait admis qu’il n’existait que deux (...) voies possibles de fondation de l’a priori - la voie historique (platonicienne) empruntée par Hegel et la voie physiologique (aristotélicienne) qui sera la nôtre - la première partie de ce second volume prendra pour acquis qu’il n’existe pas de théorie qui puisse unifier ces deux pôles du savoir. Cela impliquera une scission entre deux mouvements irrationnels que sont le mouvement entéléchique aristotélicien et le mouvement dialectique platonicien. A partir du corps a priori du surhomme, le premier mouvement sera à la racine de la théorie de la connaissance (De la science) alors que le second sera au fondement de la théorie des valeurs (De l’Idéologie). En circonscrivant le mouvement dialectique dorien autour du noûs perse (iranien), ce travail offrira une première définition totalement négative du mouvement entéléchique appuyé, lui, sur le noûs ionien (« phénicien ») dont la seconde partie sera l’objet. De l’analyse de la substance première en passant par l’étude phénoménologique des schèmes de la camusité et du membre moteur, cette étude reviendra sur l’élasticité du tendon afin d’approcher non-phénoménalement le concept lui-même et tenter ainsi une première symphyse avec les rythmes circadiens de la biologie contemporaine.

I present and I implement what I take to be the best approach to solve the meta-problem: the evidential approach. The main tenet of this approach is to explain our problematic phenomenal intuitions by putting our representations of phenomenal states in perspective within the larger frame of the cognitive processes we use to conceive of evidence.

This paper analyzes recent attempts to reject reproduction with lineage formation as a necessary condition for evolution by means of natural selection :560–570, 2008; Stud Hist Philos Sci Part C Stud Hist Philos Biol Biomed Sci 42:106–114, 2011; Bourrat in Biol Philos 29:517–538, 2014; Br J Philos Sci 66:883–903, 2015; Charbonneau in Philos Sci 81:727–740, 2014; Doolittle and Inkpen in Proc Natl Acad Sci 115:4006–4014, 2018). Building on the strengths of these attempts and avoiding their pitfalls, it is argued that (...) a robust formulation of evolution by natural selection without reproduction can be established. The main contribution of this paper is a reformulation of Lewontin’s three principles stating that minimal evolution by natural selection occurs when two conditions are met in a population: fitness-related variation and memory. Paradigmatic evolution by natural selection, which can generate adaptations, takes place when an additional condition is present, namely regeneration. (shrink)

Recent years have seen a growing interest among psychologists for debates in moral philosophy. Moral psychologists have investigated the causal origins of the opposition between utilitarian and deontological judgments and the psychological underpinnings of people’s beliefs about the moral status of animals. One issue that remains underexplored in this research area is the relationship between people’s disposition to engage in utilitarian thinking and their attitudes towards animals. This gap is unfortunate considering the tight philosophical connection between utilitarianism and the claim (...) that animals have the same moral status as humans. Indeed, the principle of utility leads naturally enough to the view that animals count every bit as much as human beings. In this paper, we report two empirical studies dedicated to bridging this gap. In Study 1, we looked at the relationship between attitudes towards animals and utilitarian judgments in the context of sacrificial dilemmas. In Study 2, we bypassed the problems raised by the use of such dilemmas as a measure of utilitarianism by relying on other types of thought experiments. Overall, our results suggest no strong correlation between utilitarianism and attitudes towards animals. Rather, the existence of a correlation between utilitarianism and attitudes towards animals very much depends on how both are measured. (shrink)

This study of Greek time before Aristotle’s philosophy starts with a commentary on his first text, the Protrepticus. We shall see two distinct forms of time emerge: one initiatory, circular and Platonic in inspiration, the other its diametrical opposite, advanced by Aristotle. We shall explore this dichotomy through a return to poetic conceptions. The Tragedians will give us an initial outline of the notion of time in the Greek world (Fate); we shall then turn to Homer in order to better (...) grasp the complex relations between time and the religious sphere (the Hero); the work of the great theologian Hesiod will confirm this initiatory vision, later set out in remarkable fashion by Nietzsche (Myths); we shall then dive deep into Pythagoreanism to complete our account (Mysteries). Having understood this current of thought, powerfully influenced by the Iranian theogony, we shall be able to discern its clear differences from the so-called “Ionian” current, and thus to move away from Plato (Ideology). Lastly, we shall return to the early Ionian thinkers Thales and Anaximander to analyse whether this really was the vision of the world that Aristotle adopted in developing the first model of time (Science). In the second volume we shall see the return of the thought of the theologoi within the Aristotelian corpus itself, and will question our distinction between the being and existence of time.

Notre étude sur le temps grec précédant la pensée d Aristote commencera d'abord par un commentaire de son premier texte, le Protreptique. Nous verrons se dégager deux temps distincts : l'un initiatique, circulaire et d'inspiration platonicienne, et l'autre diamétralement opposé dont Aristote serait le défenseur. Afin d'interroger cette dichotomie, nous retournerons aux conceptions poétiques. Les Tragiques nous permettront d'offrir une première esquisse de cette notion dans l'univers grec (Du destin...). Ensuite, l'oeuvre épique d'Homère sera l'occasion de mieux saisir le nouage (...) existant entre le temps et la sphère religieuse (Des héros...). Le travail du grand théologue Hésiode viendra confirmer cette vision initiatique, comme l'avait déjà remarquablement exposée F. Nietzsche (Des mythes...). C'est alors que nous plongerons au sein du pythagorisme afin de parachever cette vision (Des mystères...). Notre compréhension de ce courant, traversé par la théogonie iranienne, nous permettra, ensuite, de bien le distinguer de celui dit «ionien» et ainsi de s'éloigner de la parole platonicienne (De l'idéologie...). Enfin, en revenant aux premiers penseurs ioniens que furent Thalès et Anaximandre, nous analyserons si c'est effectivement cette vision du monde qui a été retenue par le Stagirite afin de fonder la première modélisation du concept de temps (De la science...). -/- Dans le deuxième volume, nous verrons revenir la pensée des théologoï au sein même du corpus aristotélicien et c'est alors que nous interrogerons notre division entre être et existence du temps. -/- Régis LAURENT est philosophe, membre de l'association Kairos kai logos (Centre d'études sur la pensée antique).Ce livre est le premier volet de son travail de thèse de doctorat en philosophie effectué au sein de trois Universités françaises (Grenoble, Clermont-Ferrand et Rennes).Outre cette formation philosophique,l'auteur est également diplômé en sciences humaines (Maîtrise des sciences du langage et maîtrise de psychologie).

Moral error theorists face the so-called “now-what problem”: what should we do with our moral judgments from a prudential point of view if these judgments are uniformly false? On top of abolitionism and conservationism, which respectively advise us to get rid of our moral judgments and to keep them, three revisionary solutions have been proposed in the literature: expressivism, naturalism, and fictionalism. In this paper, I argue that expressivism and naturalism do not constitute genuine alternatives to abolitionism, of which they (...) are in the end mere variants—and, even less conveniently, variants that are conform to the very spirit of abolitionism as formulated by its proponents. The main version of fictionalism, by contrast, provides us with a recommendation to which abolitionists cannot consistently subscribe. This leaves us with only one revisionary solution to the now-what problem. (shrink)

Oscar Horta has argued that speciesism is wrong by definition. In his view, there can be no more substantive debate about the justification of speciesism than there can be about the legality of murder, for it stems from the definition of “speciesism” that speciesism is unjustified just as it stems from the definition of “murder” that murder is illegal. The present paper is a case against this conception. I distinguish two issues: one is descriptive and the other normative. Relying on (...) philosophers’ use of the term, I first answer the descriptive question negatively: speciesism is a purely descriptive concept. Then, based on both its main functions in the philosophical and public debates and an analogy with racism, I answer the normative question negatively: speciesism should remain a purely descriptive concept. If I am correct, then speciesism neither is nor should be wrong by definition. (shrink)

Rejet de la dialectique comme objet pouvant rentrer au sein de la logique. Refoulement de la dialectique dans l'histoire. Or si la dialectique est historique alors nous pouvons la situer spatialement dans l'histoire.

Many philosophers have tried to defend physicalism concerning phenomenal consciousness, by explaining dualist intuitions within a purely physicalist framework. One of the most common strategies to do so consists in interpreting the alleged “explanatory gap” between phenomenal states and physical states as resulting from a fallacy, or a cognitive illusion. In this paper, I argue that the explanatory gap does not rest on a fallacy or a cognitive illusion. This does not imply the falsity of physicalism, but it has consequences (...) on the kind of physicalism we should embrace. (shrink)

On abordera ici l'échec du pseudo-théologien Heidegger à venir se saisir de l'irrationnel augustinien et soulignerons la différence entre l'irrationnel dorien (au bout du langage) et l'irrationnel ionien (au bout du monde) autour de la mesure.

Le structuralisme, en le rapprochant du langage, a détruit le concept freudien de "Verdichtung" (condensation). Il s'agissait chez Freud d'un mouvement irrationnel dont la rationalité ne venait que de la cause finale qu'était le désir (inconscient). Avec sa notion de "Volonté de Puissance" (Der Wille zur Macht), Nietzsche tente de la même manière de déterminer l'intention et l’extension de ce mouvement de sens sans introduire la cause finale comme le fit Freud. Il s'approche alors de la dialectique platonicienne et de (...) son fondement, avant de plonger dans l'abyme de la source iranienne (perse). L'échec de la métabiologie de Nietzsche sera le départ de notre approche métabiologique appuyée sur la métaphysique d'Aristote et Kant. (shrink)

What does it take for lawyers and others to think or talk about the same legal topic—e.g., defamation, culpability? We argue that people are able to think or talk about the same topic not when they possess a matching substantive understanding of the topic, as traditional metasemantics says, but instead when their thoughts or utterances are related to each other in certain ways. And what determines the content of thoughts and utterances is what would best serve the core purposes of (...) the representational practice within which the thought or utterance is located. In thus favoring a “relational model” in metasemantics, we share Ronald Dworkin's goal of explaining fundamental legal disagreements, and also his reliance on constructive interpretation. But what we delineate is a far more general and explanatorily resourceful metasemantics than what Dworkin articulated, which also bypasses some controversial implications for the nature of law that Dworkin alleged.

In 'Ethics Without Sentience: Facing Up to the Probable Insignificance of Phenomenal Consciousness' (Kammerer, 2022), I argued that phenomenal consciousness is probably normatively insignificant, and does not play a significant normative role. In 'Preserving the Normative Significance of Sentience' (Dung, 2024), Leonard Dung challenges my reasoning and defends sentientism about value and moral status against my arguments. Here I respond to Dung's criticism, pointing out three flaws in his reply. My conclusion is that the view that phenomenal consciousness is distinctively (...) significant is still very much under threat. (shrink)

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

We present bibliometric evidence for increasing estrangement between the philosophy of economics and economics itself. Our analysis centers on research articles published in the Journal of Economic Methodology (JEM) between 1994 and 2021. We analyze the citations within these research articles, in particular with respect to the citations of economics. Our results are fourfold. (1) The share of economic citations in JEM articles has been decreasing. (2) The remaining economic citations in JEM articles are increasingly older relative to citation patterns (...) within economics. (3) The profile of economic citations in JEM articles is increasingly dissimilar when compared to what is cited within economics. (4) There is decreasing diversity with regards to the share of attention towards different economic subfields in the articles published in JEM when compared to economics. We discuss interpretations of this evidence for estrangement between philosophy of economics and economics. (shrink)

On the basis of two thought experiments, I argue that self-building technologies are possible given our current level of technological progress. We could already use technology to make us instantiate selfhood in a more perfect, complete manner. I then examine possible extensions of this thesis, regarding more radical self-building technologies which might become available in a distant future. I also discuss objections and reservations one might have about this view.

Illusionists claim that phenomenal consciousness does not exist, but merely seems to exist. Most debates concerning illusionism focus on whether or not it is true—whether phenomenal consciousness really is an illusion. Here I want to tackle a different question: assuming illusionism is true, what kind of illusion is the illusion of phenomenality? Is it a “rich” illusion—the cognitively impenetrable activation of an incorrect representation—or a “sparse” illusion—the cognitively impenetrable activation of an incomplete representation, which leads to drawing incorrect judgments? I (...) present this distinction and I classify the most influential illusionist theories along this line of divide. I then offer an argument against the accounts of the illusion of phenomenality in terms of sparse illusion. (shrink)

Our societies are marked by anthropocentrism: most people treat animals in ways in which they would by no means treat fellow humans. One might nonetheless expect this prejudice to be much less prevalent in animal shelters since these places are created for the very sake of non-humans and generally managed by people who truly care about animal welfare. This chapter questions this expectation. It discusses three practices that are widespread in animal shelters and yet could be suspected of anthropocentrism: killing (...) animals for lack of resources, partnering with the livestock industry, and feeding animals meat. Drawing on the distinction between ideal and non-ideal theory, the chapter argues that management euthanasia and cooperation with animal agriculture are acceptable in non-ideal theory even though they would be condemned by ideal theory. Then it argues that meat-based pet food should be rejected even in the non-ideal circumstances faced by animal shelters. (shrink)

Animal ethicists often distinguish between direct and indirect defenses of speciesism, where the former appeal to species membership and the latter invoke other features that are simply associated with it. The main extant charge against indirect defenses rests on the empirical claim that any feature other than membership in our species is either absent in some humans or present in some nonhumans. This paper challenges indirect defenses with a new argument, which presupposes no such empirical claim. Instead, the argument from (...) discordance resorts to the following principle: a certain feature can only justify discriminating on the basis of that feature. (shrink)

ARISTOTE contre LEIBNITZ : En quoi le concept d'Entéléchie aristotélicien est-il totalement opposé au concept d'Harmonie platonicien et leibnitzien ?

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

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

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

In recent years Fodor has repeatedly argued that nothing epistemic can be essential to, or constitutive of, any concept. This holds in virtue of a constraint which Fodor dubs the Compositionality Constraint. I show that Fodor's argument is fallacious because it rests on an ambiguity.
