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)

Illusionists about consciousness boldly argue that phenomenal consciousness does not fundamentally exist — it only seems to exist. For them, the impression of having a private inner life of conscious qualia is nothing more than a cognitive error, a conjuring trick put on by a purely physical brain. Some phenomenal realists have accused illusionism of being a byproduct of modern Western scientism and overzealous naturalism. However, Jay Garfield has endorsed illusionism by explicitly drawing support from the classical Yogācāra Buddhist philosopher (...) Vasubandhu. In this paper, I assess the degree to which Garfield’s illusionist interpretation accurately captures the views of Vasubandhu and his commentator Sthiramati in their extant Sanskrit works. As it turns out, Vasubandhu and Sthiramati converge with contemporary illusionists in taking an unconscious causal basis of cognitive/linguistic processes to be responsible for generating the illusion of representational states with apparently phenomenal contents. Within their constitutive understanding of the mind as the “imagination of what is non-existent” (abhūtaparikalpa), I raise possible candidates for what might seem to be real instances of phenomenality — mental appearances (pratibhāsa), affective sensory experience (vedanā), and “intrinsic luminosity” (prakṛtiprabhāsvara) — and consider possible responses on behalf of an illusionist interpreter. I conclude that Vasubandhu and Sthiramati really do appear to be strong illusionists about phenomenal consciousness, particularly if phenomenal states are assumed to be essentially representational.

Self-consciousness relates to important themes, such as sentience and personhood, and is often the cornerstone of moral theories (Warren, 1997). However, not much attention is given to future moral creatures of the earth: robots. This may be due to the unsettled status of their experience, which is why I have chosen to find the necessary features of self-consciousness in them. Philosophy of mind is also my interest which I have developed since I rejected the idea of souls and could not (...) account for my own phenomenal experiences. Among the current answers to the hard problem of consciousness (Chalmers, 1995) one stood out to me – Daniel Dennett’s multiple drafts model of consciousness presented in “Consciousness Explained” (Dennett, 1991) and his other works. Daniel Dennett is a self-described illusionist (Dennett, 2016) and a functionalist. His position is synonymous to holding self-conscious experiences, such as deliberating over one’s pain or reflecting over one’s actions insufficient to postulate existence of a metaphysical self. He believes instead that experiences are functional realizations which do not require any self, and the feeling of being conscious or self-conscious is actually a ”user-illusion” (Dennett, 1991), a term describing the unjustified belief of being in control of one’s actions. In his views, a selfhood as it is popularly conceived is contradictory. Therefore, he rejects realism about mental events, a position also called naïve realism (Siegel, 2011), on the basis that it is unverifiable and there are insufficient grounds to accept mental events (Dennett, 1988). He adopts a similar scepticism towards other theories of minds, hence nearing eliminative materialism in self-consciousness and related theme of pain (Dennett, 1978). His multiple drafts model of consciousness seeks to ground our beliefs about self-consciousness in the specific architecture of mind, which is particular to every species and kind of being. As such it is a particularly flexible theory that examines experiences of non-humans without falling into binary thinking – believing that a being has as rich inner life as humans do or none. This is why it is a great starting point for establishing necessary conditions for consciousness in robots. In this essay, I will often use words computer, programme, robot interchangeably for the purpose of clarity and take as the working definition “autonomous machines capable of sensing their environment, making decision and performing tasks similar to human actions”. I chose to explore self-consciousness instead of committing to the issue of consciousness, because consciousness can be defined in a weak sense, in which even a thermostat is “conscious” of the temperature, and consciousness in a strong sense, which invokes the internalism and externalism debate that is less connected to the nature of experiences than self-consciousness. My exploration pertains first and foremost to the philosophy of mind, of which I will examine the most relevant positions and decide to commit to functionalism (Block, 1980). Then I will advocate for explaining away of some of phenomena of self-consciousness and believing self-consciousness to be a sort of illusion. From there I will conclude that robots could fall for the same illusion of self-consciousness and therefore become self-conscious. I will argue, that self-consciousness can be established using a modified Turing Test, which would determine if a robot believed in a meaningful narrative about itself (Ricoeur, 1991) and hence be self-conscious. This will lead to answering the question of this essay: what are the features necessary for a self-conscious robot in the light of “Consciousness Explained” by Daniel Dennett? (shrink)

Most recent philosophical theories of consciousness account for it in terms of representation, the bulk of the debate revolving around whether (suitably) representing something is sufficient for consciousness (as per first-order representationalism) or some further (meta-)representation is needed (as per higher-order representationalism and self-representationalism). In this paper, I explore an alternative theory of consciousness, one that aims to explain consciousness not in terms of representation but in terms of the epistemically and metaphysically direct relation of acquaintance. I call this the (...) Inner Acquaintance Theory of consciousness (IAT). Roughly, on IAT, what makes a mental state conscious is its subject being acquainted with it. Though not wholly unprecedented, IAT is still at the fringe of consciousness debates and remains largely underexplored. The main goal of this paper is to take some steps toward developing the details of IAT, illustrate its potential explanatory power, and put it forward as a plausible alternative to representational theories, with the hope that this will contribute to shifting IAT closer to the center of the debate. Here is how I proceed. In §2 I introduce a notion—inner awareness—that is crucial both to contextualize and to understand IAT. In §3 I provide some preliminary motivation for exploring IAT. In §4 I explain the notion of acquaintance and illustrate some of the features that are typically attributed to it in the literature. The details of IAT are then shaped through four main decision points. I address them in §§5-8, where I suggest a particular choice at each decision point, thereby progressively building up a view that I consider particularly promising. (shrink)

Consciousness-based approaches to non-human moral status maintain that consciousness is necessary for (some degree or level of) moral status. While these approaches are intuitive to many, in this paper I argue that the judgment that consciousness is necessary for moral status is not secure enough to guide policy regarding non-humans, that policies responsive to the moral status of non-humans should take seriously the possibility that psychological features independent of consciousness are sufficient for moral status. Further, I illustrate some practical consequences (...) of calling consciousness-based views into question. (shrink)

The primary goal of this paper is to provide substantial motivation for exploring an Acquaintance account of phenomenal consciousness, on which what fundamentally explains phenomenal consciousness is the relation of acquaintance. Its secondary goal is to take a few steps towards such an account. Roughly, my argument proceeds as follows. Motivated by prioritizing naturalization, the debate about the nature of phenomenal consciousness has been almost monopolized by representational theories. Among them, Self-Representationalism is by far the most antecedently promising. However, on (...) thorough inspection, Self-Representationalism turns out not explanatorily or theoretically better than the Acquaintance account. Indeed, the latter seems to be superior in at least some important respects. Therefore, at the very least, there are good reasons to take the Acquaintance account into serious consideration as an alternative to representational theories. The positive contribution of this paper is a sketch of an account of consciousness on which phenomenal consciousness is explained partly in representationalist terms, but where a crucial role is played by the relation of acquaintance.

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.

Most people believe that consciousness is real. But illusionists say it isn’t—they say consciousness is an illusion. One common illusionist strategy for defending their view involves a debunking argument. They explain why people _believe_ that consciousness exists in a way that doesn’t imply that it _does_ exist; and, in so doing, they aim to show that that belief is unjustified. In this paper I argue that we can know consciousness exists even if these debunking arguments are sound. To do this, (...) I draw on the claim that some knowledge is constituted, not by beliefs in propositions, but by awareness of properties and objects. Then I argue that accepting this claim allows us to evade illusionists’ debunking arguments by allowing us to hold that our knowledge of consciousness does not depend solely on potentially debunked _beliefs_ in consciousness. Finally, while considering potential illusionist responses, I suggest that my strategy also yields a plausible account of our most basic knowledge of consciousness and an explanation for why so few people accept illusionism even when they have (or had) no decisive reply to illusionists’ arguments.

Fifteen years ago, Sharon Street and Richard Joyce advanced evolutionary debunking arguments against moral realism, which purported to show that the evolutionary history of our moral beliefs makes moral realism untenable. These arguments have since given rise to a flurry of objections; the epistemic principles Street and Joyce relied upon, in particular, have come in for a number of serious challenges. My goal in this paper is to develop a new account of evolutionary debunking which avoids the pitfalls Street and (...) Joyce encountered and responds to the most pressing objections they faced. I begin by presenting a striking thought experiment to serve as an analogy for the evolution of morality; I then show why calibrationist views of higher-order evidence are crucial to the evolutionary debunking project; I outline a new rationale for why finding out that morality was selected to promote cooperation suggests that our moral judgments are unreliable; and I explain why evolutionary debunking arguments do not depend on our having a dedicated faculty for moral cognition. All things considered, I argue, evolutionary debunking arguments against moral realism are on relatively secure footing – provided, at least, that we accept a calibrationist account of higher-order evidence.

Creativity is intrinsic to Humanities and STEM disciplines. In the activities of artists and engineers, for example, an attempt is made to bring something new into the world through counterfactual thinking. However, creativity in these disciplines is distinguished by differences in motivations and constraints. For example, engineers typically direct their creativity toward building solutions to practical problems, whereas the outcomes of artistic creativity, which are largely useless to practical purposes, aspire to enrich the world aesthetically and conceptually. In this essay, (...) an artist (DHS) and a roboticist (GS) engage in a cross-disciplinary conceptual analysis of the creative problem of artificial consciousness in a robot, expressing the counterfactual thinking necessitated by the problem, as well as disciplinary differences in motivations, constraints, and applications. We especially deal with the question of why one would build an artificial consciousness and we consider how an illusionist theory of consciousness alters prominent ethical debates on synthetic consciousness. We discuss theories of consciousness and their applicability to synthetic consciousness. We discuss practical approaches to implementing artificial consciousness in a robot and conclude by considering the role of creativity in the project of developing an artificial consciousness.

Some philosophers consider that some of their colleagues deny that consciousness exists. We shall call the latter ‘deniers’, adopting a term that was initially meant pejoratively. What do the deniers deny? In order to answer this question, we shall examine arguments, both of some deniers and of their critics, and present denialism as a systematic highly non-trivial position that has had some interesting achievements. We will show that the denialist project concerns the epistemology of the mind and specifically of consciousness: (...) what can be known about it, and how it can be known. The main argument of denialism is that first-person reports about the mental realm are not always the best source of information about that realm, and are certainly not reliable. This leads the deniers to realize that the reference and meaning of mental terms as used in standard philosophical literature are vague and call for clarification, and that what many take to be empirical data in the study of the mind are actually heavily laden with theory. Denialism thus makes scientific and philosophical research clearer and more fruitful. (shrink)

In a recent paper in this journal, David Chalmers introduced the meta-problem of consciousness as “the problem of explaining why we think consciousness poses a hard problem” (Chalmers, 2018, p. 6). A solution to the meta-problem could shed light on the hard problem of consciousness. In particular, it would be relevant to elucidate whether people’s problem intuitions (i.e. intuitions holding that conscious experience cannot be reduced to physical processes) are driven by factors related to the nature of consciousness, or rather (...) by factors that are independent of consciousness. Whether people hold problem intuitions, and what factors drive those intuitions, are largely empirical questions. However, there is a lack of empirical research on these issues to date. The results of four studies will show that (1) problem intuitions are not widespread, and (2) when they arise, they do so because of factors that are unrelated to the nature of consciousness. This suggests that consciousness is, after all, not so problematic. (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)

‘Space does not exist fundamentally: it emerges from a more fundamental non-spatial structure.’ This intriguing claim appears in various research programs in contemporary physics. Philosophers of physics tend to believe that this claim entails either that spacetime does not exist, or that it is derivatively real. In this article, I introduce and defend a third metaphysical interpretation of the claim: reductionism about space. I argue that, as a result, there is no need to subscribe to fundamentality, layers of reality and (...) emergence in order to analyse the constitution of space by non-spatial entities. It follows that space constitution, if borne out, does not provide empirical evidence in favour of a stratified, Aristotelian in spirit, metaphysics. The view will be described in relation to two particular research programs in contemporary physics: wave function realism and loop quantum gravity. (shrink)

To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and pluralistic approaches have intensified the debate, (...) rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

: In this paper I approach the problem of the boundaries and location of consciousness in a strictly physicalist way. I start with the debate on extended cognition, pointing to two unresolved issues: the ontological status of cognition and the fallacy of the center. I then propose using identity to single out the physical basis of consciousness. As a tentative solution, I consider Mind-Object Identity and compare it with other identity theories of mind. Keywords: Extended Mind; Spread Mind; Enactivism; Cognition; (...) Consciousness; Mind-Object Identity; Identity I confini e la localizzazione della coscienza secondo le teorie dell’identità Riassunto: In questo lavoro tratterò il problema dei confini e della localizzazione della coscienza in termini strettamente fisicalisti. Prenderò le mosse dal dibattito sulla cognizione estesa, portando l’attenzione su due questioni irrisolte: lo status ontologico della cognizione e la fallacia del centro. Proporrò quindi di usare l’identità per individuare la base fisica della coscienza. Come possibile soluzione, prenderò in considerazione la Mind-Object Identity, confrontandola con oltre teorie dell’identità della mente.

[Replies to My Friends] This is an answer to the critics of my book WHAT IT'S LIKE, OR WHAT IT'S ABOUT? THE PLACE OF CONSCIOUSNESS IN THE MATERIAL WORLD (2017). I proceed from the least to the most serious objections. I start with Jakub Mihálik’s defense of Russellian Monism against my claim that it is not a genuine alternative to standard dualism and materialism. In reply, I claim this is a side issue to the central aim of my book, which (...) is to undermine the concept of phenomenal consciousness assumed by Russellian Monism as much as by every other standard theory. One of these standard theories is reductive materialism, pursued by Michal Polák and Tomáš Marvan. Both Polák and Marvan are worried by Dennett’s alleged eliminativism, even though their arguments somewhat differ. Polák believes in a deflationary concept of consciousness, which I am afraid lacks a definite content. Marvan offers an “innocent” concept of consciousness, on which there is supposed to be a general consensus, but I think he just assumes that the concept of phenomenal property is part of the definition of consciousness. Curiously, while Polák and Marvan take me as to be a Dennettian, Stefanie Dach argues that I misinterpret Dennett. Conversely, I believe that she overlooks weak points in Dennett’s theory. (shrink)

The philosophers’ concept of qualia is an artifact of bad theorizing, and in particular, of failing to appreciate the distinction between the intentional object of a belief and the cause of that belief. Qualia, like Santa Claus and the Easter Bunny, have a history but that does not make them real. The cause of a hallucination, for instance, may not resemble the intentional object hallucinated at all, and the representation in the brain is not rendered in special subjective properties.

There is a long-standing tradition of questioning the viability and scientificity of first-person methods. Husserlian reflective methodology, in particular, has been challenged on the basis of its perceived inability to meet the standards of objectivity and reliability, leading to what has been called “phenomenological skepticism” ( Roy, 2007 ). In this article, I reassess this line of objection by outlining Daniel C. Dennett’s empirically driven skepticism and reconstructing his methodological arguments against Husserlian phenomenology. His ensuing phenomenological skepticism is divided into (...) strong skepticism and categorical and gradual versions of weak skepticism. Both strands of Dennett’s criticism are then countered by analyzing the key components of Husserl’s method of phenomenological reflection: epoché and transcendental reduction, intentional analysis, eidetic variation, and intersubjective validation. Laying out the basic features of phenomenological reflection serves two purposes. First, it undermines Dennett’s methodological arguments, which are based on the unfounded assumptions that Husserl is committed to introspection, methodological solipsism, the first-person-plural presumption, and the lone-wolf approach. Second, it shows how Husserl’s own methodology can alleviate the more justified empirical worries concerning overinterpretation, underdescription, and disagreement. Finally, I argue that gradual weak skepticism is the only plausible form of phenomenological skepticism and conclude that Husserlian methodology is well-equipped to combat it. (shrink)

Integrated information theory is a theory of consciousness that was originally formulated, and is standardly still expressed, in terms of controversial interpretations of its own ontological and epistemological basis. These form the orthodox interpretation of IIT. The orthodox epistemological interpretation is the axiomatic method, whereby IIT is ultimately derived from, justified by, and beholden to a set of phenomenological axioms. The orthodox ontological interpretation is panpsychism, according to which consciousness is fundamental, intrinsic, and pervasive. In this paper it is argued (...) that both components of the orthodox interpretation should be rejected. But IIT should not be rejected since an interpretation-neutral formulation is available. After explaining the neutral formulation, more plausible non-axiomatic epistemologies are defended. The neutral formulation is then shown to be consistent with various contemporary physicalist ontologies of consciousness, including the phenomenal concept strategy, representationalism, and even illusionism. Along the way, instructive connections between interpretations of IIT and interpretations of quantum mechanics are noted. (shrink)
