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)

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 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.

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.

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)

In 'Illusionism as a Theory of Consciousness', Frankish argues for illusionism: the thesis that phenomenal consciousness does not exist, but merely seems to exist. Illusionism, he says, 'replaces the hard problem with the illusion problem -- the problem of explaining how the illusion of phenomenality arises and why it is so powerful'. The illusion of phenomenality is indeed quite powerful. In fact, it is much more powerful than any other illusion, in the sense that we face a very special and (...) unique intuitive resistance when trying to accept that phenomenality is an illusion. This is bad news for illusionists, because this means that they cannot entirely model their explanation of the illusion of consciousness on the explanation of other illusions. Explaining this unique intuitive resistance to illusionism may therefore constitute the hardest aspect of the illusion problem. However, I think that this aspect of the problem is solvable. I will outline a possible solution, which is based on the hypothesis that our (illusory) introspective representations of phenomenal states characterize them as having unique epistemological properties and as playing a special epistemological role.

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)

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.

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)

Does phenomenal consciousness overflow access consciousness? Some researchers have claimed that it does, relying on interpretations of various psychological experiments such as Sperling's or Landman's, and crucially using alleged subjective reports from participants to argue in favor of these interpretations. However, systematic empirical investigations of participants' subjective reports are scarce. To fill this gap, we reproduced Sperling's and Landman's experiments, and carefully collected reports made by subjects about their own experiences, using questionnaires and interviews. We found that participants' subjective reports (...) do not support the overflow thesis, but rather suggest alternative interpretations of the experiments. (shrink)

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)

In a recent paper, Eric Schwitzgebel argues that if materialism about consciousness is true, then the United States is likely to have its own stream of phenomenal consciousness, distinct from the streams of conscious experience of the people who compose it. Indeed, most plausible forms of materialism have to grant that a certain degree of functional and behavioral complexity constitutes a sufficient condition for the ascription of phenomenal consciousness – and Schwitzgebel makes a case to show that the United States (...) as a whole fulfills this condition. One way to avoid this counter-intuitive consequence of materialism about consciousness is to adopt what Schwitzgebel calls an “anti-nesting principle”: a principle that states that there can be no nested forms of phenomenal consciousness and that therefore a conscious whole cannot have parts that are themselves conscious. However, Schwitzgebel then proceeds in his paper to draw up various objections, notably based on thought experiments, in order to dismiss these kinds of “anti-nesting” principles. My aim in this paper is to present a version of a sophisticated anti-nesting principle that avoids Schwitzgebel’s objections. This principle is reasonable, intuitive, and as non-arbitrary as possible. Moreover, it can resist the objections mounted by Schwitzgebel against simple anti-nesting principles. This principle helps materialists avoid the implication that the United States has its own stream of consciousness, while granting consciousness to some entities which, in many cases, are intuitive instantiators of phenomenal consciousness. This principle therefore constitutes a way out for a materialist who wants to deny that the United States is conscious. (shrink)

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)

Numerous philosophers have recently tried to defend physicalism regarding phenomenal consciousness against dualist intuitions, by explaining the existence of dualist intuitions within a purely physicalist framework. David Papineau, for example, suggested that certain peculiar features of some of our concepts of phenomenal experiences (the so-called “phenomenal concepts”) led us to commit what he called the “Antipathetic Fallacy”: they gave us the erroneous impression that phenomenal experiences must be distinct from purely physical states (the “intuition of distinctness”), even though they are (...) not. Papineau’s hypothesis has been accepted, though under other names and in different forms, by many physicalist philosophers. Pär Sundström has tried to argue against Papineau’s account of the intuition of distinctness by showing that it was subjected to counterexamples. However, Papineau managed to show that Sundström’s counterexamples were not compelling, and that they could be answered within his framework. In this paper, I want to draw inspiration from Sundström, and to put forth some refined counterexamples to Papineau’s account, which cannot be answered in the same way as Sundström’s. My conclusion is that we cannot explain the intuition of distinctness as the result of a kind of “Antipathetic Fallacy”. (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.

Why do we tend to think that phenomenal consciousness poses a hard problem? The answer seems to lie in part in the fact that we have the impression that phenomenal experiences are presented to us in a particularly immediate and revelatory way: we have a sense of acquaintance with our experiences. Recent views have offered resources to explain such persisting impression, by hypothesizing that the very design of our cognitive systems inevitably leads us to hold beliefs about our own experiences (...) with certainty. I argue against this kind of “designed certainty” views. First, I claim that it is doubtful that we really hold beliefs about our own experiences with certainty—in any sense of certainty that would make our phenomenal beliefs special. Second, I claim that, even if it were the case that we hold beliefs about experiences with certainty, this would fall short of explaining our sense of acquaintance. (shrink)

Dans « Représentationnalisme et langage privé », François Kammerer s’attache à la thèse dite du représentationnalisme qui, au regard de la conscience phénoménale, pose que les propriétés qualitatives d’une expérience consciente sont entièrement déterminées par ses propriétés représentationnelles ; de nombreux arguments ont été proposés en faveur de cette thèse, qui est devenue l’orthodoxie en philosophie de l’esprit contemporaine. L’auteur entend réfuter les arguments les plus significatifs, en se fondant sur des considérations de Wittgenstein sur l’impossibilité d’un « (...) langage privé ». (shrink)

The Phenomenal Concept Strategy is a popular strategy used to support physicalism in the realm of conscious experience. This Strategy accounts for dualist intuitions but uses the ways in which we think about our experiences to explain these intuitions in a physicalist framework, without any appeal to ontological dualism. In this paper, I will raise two issues related to the currently available versions of the Phenomenal Concept Strategy. First, most of the theories belonging to the Phenomenal Concept Strategy posit that (...) phenomenal concepts are exceptional and sui generis concepts, and these theories can be shown to be largely ad hoc. Second, these theories may explain the existence of anti-physicalist intuitions, but they do not explain their persistence. My aim is to put forward a new theory of phenomenal concepts that can rise up to these challenges to the Phenomenal Concept Strategy. In my view, phenomenal concepts are not independent and sui generis concepts. On the contrary, they are closely related to our other epistemic concepts, especially our concepts of “justification”. Thinking about an experience means thinking about a specific kind of justification – an unjustified justification, or, in other words, an “ultimate seeming”. I will show why this explains the existence and the persistence of antiphysicalist intuitions in a non-ad hoc way. (shrink)

Nietzsche est souvent perçu comme un philosophe de la critique du " moi ", qui entreprend d'évacuer le sujet souverain pour en faire un simple effet des rapports entre les volontés de puissance. L'ambition de ce livre est de montrer qu'une telle vision est incomplète. Il y a dans l'œuvre de Nietzsche, et particulièrement dans son dernier livre, Ecce Homo, une forte pensée de l'individu et du rapport à soi qui, loin d'éliminer le problème de la subjectivité, le pose à (...) nouveaux frais. Ce livre procède en deux temps. Tout d'abord, il revient sur l'ensemble du corpus nietzschéen afin de distinguer les différentes critiques que Nietzsche adresse aux notions de " moi ", d'individu, de sujet, et fait apparaître les perspectives ainsi ouvertes. Il s'intéresse ensuite plus particulièrement à Ecce Homo. En convoquant les pensées d'auteurs comme Foucault, Deleuze ou Simondon, il interprète ce dernier ouvrage comme l'effectuation d'un mode de subjectivation inédit : une nouvelle manière de se rapporter à soi et d'en faire le récit. Il tente alors d'analyser ce " moi " spécifiquement nietzschéen, et d'en repérer tant le mode d'apparition que le régime d'action et d'existence. (shrink)

This editorial introduces the Journal of Consciousness Studies special issue on "Animal Consciousness". The 15 contributors and co-editors answer the question "How should we study animal consciousness scientifically?" in 500 words or fewer.

Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task‐relevant features. The authors focused on the recognition heuristic, so the task‐relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty‐three three‐member groups performed an inference task in which they had to infer which of two German companies had (...) the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Should We Live Forever? The Ethical Ambiguities of Aging by Gilbert MeilaenderCharles L. Kammer IIIShould We Live Forever? The Ethical Ambiguities of Aging Gilbert Meilaender grand rapids, mi: eerdmans, 2013. 135 pp. $18.00.Should We Live Forever? The Ethical Ambiguities of Aging provides a helpful focus on both aging and research being done to extend human life expectancy. As Gilbert Meilaender notes, human beings have always longed for an (...) extended as well as a more generative life span. He raises the question, however, of whether these two desires stand in opposition. Built into our very biology is the “survival instinct,” along with the imaginative ability to transcend our biological limits. Together they generate a religious legacy of imagining life after death. But Meilaender believes we have moved into a different time. Citing John Gray, he asserts that “the hope of life after death has been replaced by the faith that death can be defeated” (xi).Meilaender presents scientific research on antiaging while observing that there is little cultural reflection on its impacts or desirability. This book steps in to provide a reflection on these larger questions from the perspective of the virtues, or what constitutes a truly “good and human” life. As the author notes, our reflections on aging and immortality are tied to our assumptions of what it means to be human. This is evident, for example, among members of the transhumanist movement, which envisions a human brain freed from dependence on a biological body. He surmises that our scientific quest for immortality may have its roots in the human quest to overcome contingency and its associated anxiety; it is in many ways the embodiment of our wish to be “gods” who have total control over our destinies.Meilaender uses classic and modern Western philosophers and theologians (including Aristotle, Augustine, Søren Kierkegaard, and Karl Barth) as well as the work of life-stage theorists (Erik Erikson and Bernard Williams) who contribute to the discussion of what constitutes a “fully human life.” Would biological immortality make a life more fully human, or is it rooted in a crass form of narcissism that makes our own survival more important than the needs and perhaps even the possibility of future generations?The book closes with a brief conversation between three friends who represent different perspectives, a useful discussion tool for raising the deeper issues presented in the book. According to the first view, we are biological organisms with prescribed natural limits; fulfillment therefore comes through accepting and finding provisional fulfillment in each of our life stages. The [End Page 216] second perspective sees human freedom and reason as the fundamental characteristics of being human and so advocates expanding life expectancy and following wherever human creativity leads. The third observes that we are constrained by our biology and yet are also free, both bound and transcendent. This perspective, however, notes that what we truly desire is not an indefinite extension of life but something richer and fuller that transcends any possibility that humans can create. Our longing is not actually a desire for more but a desire for something other than what continued existence can provide.Meilaender’s engagement of the deeper questions presented by the scientific attempt to “cure” aging and extend life indefinitely is, finally, a powerful Christian apologetic that is nevertheless respectful of other positions. If the book has a limitation, it lies in the failure to engage non-Western traditions that perceive and address the issues from much different frameworks. It also does not address the possibility that perhaps being human is to live with the awareness and resignation that, while we have a deep desire for something qualitatively fuller and richer, this is a longing that can never be fulfilled.Charles L.

Il est assez rare qu’un concept philosophique s’échappe de l’arène académique. C’est pourtant le cas du concept de spécisme, qui a fait une entrée remarquée dans la sphère publique au cours de la dernière décennie. Il est désormais au cœur du débat de société sur nos devoirs envers les animaux non humains. Hélas, ce concept et les enjeux qu’il soulève sont souvent mal compris. Nombreux sont les auteurs qui contestent sa légitimité alors qu’ils le maitrisent mal. D’autres l’utilisent plus volontiers (...) sans toutefois mieux le comprendre. Les confusions qui entourent cette notion l’empêche de contribuer à la discussion autant qu’elle le pourrait. Le présent ouvrage entend remédier à cet état de faits en donnant de la notion de spécisme une présentation à la fois assez précise pour rendre justice aux discussions philosophiques dont elle fait l’objet et suffisamment claire pour être accessible à quiconque s’intéresse au statut moral des animaux. Il se divise en deux parties. La première aborde des questions ontologiques : Qu’est-ce exactement que le spécisme ? À quelles conditions existe-t-il ? Ces conditions sont-elles remplies dans les faits ? Quant à la seconde, elle porte sur des questions éthiques : Le spécisme peut-il être justifié ? Faut-il au contraire le condamner au même titre que le racisme et le sexisme ? (shrink)

Cumulative technological culture (CTC) refers to the increase in the efficiency and complexity of tools and techniques in human populations over generations. A fascinating question is to understand the cognitive origins of this phenomenon. Because CTC is definitely a social phenomenon, most accounts have suggested a series of cognitive mechanisms oriented toward the social dimension (e.g., teaching, imitation, theory of mind, and metacognition), thereby minimizing the technical dimension and the potential influence of non-social, cognitive skills. What if we have failed (...) to see the elephant in the room? What if social cognitive mechanisms were only catalyzing factors and not thesufficient and necessaryconditions for the emergence of CTC? In this article, we offer an alternative, unified cognitive approach to this phenomenon by assuming that CTC originates in non-social cognitive skills, namely technical-reasoning skills which enable humans to develop the technical potential necessary to constantly acquire and improve technical information. This leads us to discuss how theory of mind and metacognition, in concert with technical reasoning, can help boost CTC. The cognitive approach developed here opens up promising new avenues for reinterpreting classical issues (e.g., innovation, emulation vs. imitation, social vs. asocial learning, cooperation, teaching, and overimitation) in a field that has so far been largely dominated by other disciplines, such as evolutionary biology, mathematics, anthropology, archeology, economics, and philosophy.

Plato’s works have been the object of countless interpretations and recuperations ever since Greek antiquity. In the context of prenazi Germany, the writer Hans F.K.

The present article tries to set forth what is at stake in that propaganda piece, its historical context, as (...) well as the disquieting implications of such an “appropriation” of classical philosophy to purely political ends.

Diversity of evidence is widely claimed to be crucial for evidence amalgamation to have distinctive epistemic merits. Bayesian epistemologists capture this idea in the variety-of-evidence thesis: ceteris paribus, the strength of confirmation of a hypothesis by an evidential set increases with the diversity of the evidential elements in that set. Yet, formal exploration of this thesis has shown that it fails to be generally true. This article demonstrates that the thesis fails in even more circumstances than recent results would lead (...) us to expect. Most importantly, it can fail whatever the chance that the evidential sources are unreliable. Our results hold for two types of degrees of variety: reliability independence and testable aspect independence. We conclude that the variety-of-evidence thesis can, at best, be interpreted as an exception-prone rule of thumb. (shrink)

La philosophie bergsonnienne a rendu le monde de ses contemporains moins opaque, les aidant à lui trouver un sens. Si la France cartésienne coïncide avec les partisans de la démocratie parlementaire ancrée à gauche, celle de Bergson recrute ses plus gros bataillons dans la droite nationale, conservatrice, mais également dans une gauche antiparlementaire, révolutionnaire.

The variety-of-evidence thesis has been criticized by Bovens and Hartmann. This article points to two limitations of their Bayesian model: the conceptualization of unreliable evidential sources as randomizing and the restriction to comparing full independence to full dependence. It is shown that the variety-of-evidence thesis is rehabilitated when unreliable sources are reconceptualized as systematically biased. However, it turns out that allowing for degrees of independence leads to a qualification of the variety-of-evidence thesis: as Bovens and Hartmann claimed, more independence does (...) not always imply stronger confirmation.

This article maintains that an important class of scientific generalizations should be reinterpreted: they have typically been understood as ceteris paribus laws, but are, in fact, generics. Four arguments are presented to support this thesis. One argument is that the interpretation in terms of ceteris paribus laws is a historical accident. The other three arguments draw on similarities between these generalizations and archetypal generics: they come with similar inferential commitments, they share a syntactic form, and the existing theories to make (...) sense of them are alike. Once these generalizations are properly understood as generics, the recent cognitive approach to generics can be extended to the study of the relevant sciences. The last section indicates ways in which this extension is fruitful for the two strands of research that we combine: the philosophy of science literature on generalizations and the semantics literature on generics.

This article examines two theses formulated by Russo and Williamson in their study of causal inference in the health sciences. The two theses are assessed against evidence from a specific case in the social sciences, i.e., research on the institutional determinants of the aggregate unemployment rate. The first Russo–Williamson Thesis is that a causal claim can only be established when it is jointly supported by difference-making and mechanistic evidence. This thesis is shown not to hold. While researchers in my case (...) study draw extensively on both types of evidence, one causal claim out of the three analyzed is established even though it is exclusively supported by mechanistic evidence. The second Russo–Williamson Thesis is that standard accounts of causality fail to handle the dualist epistemology highlighted in the first Thesis. I argue that a counterfactual-manipulationist account of causality—which is endorsed by many philosophers as well as many social scientists—can perfectly make sense of the typical strategy in my case study to draw on both difference-making and mechanistic evidence; it is just an instance of the common strategy of increasing evidential variety.
