It is often thought that consciousness has a qualitative dimension that cannot be tracked by science. Recently, however, some philosophers have argued that this worry stems not from an elusive feature of the mind, but from the special nature of the concepts used to describe conscious states. Marc Champagne draws on the neglected branch of philosophy of signs or semiotics to develop a new take on this strategy. The term “semiotics” was introduced by John Locke in the modern period – (...) its etymology is ancient Greek, and its theoretical underpinnings are medieval. Charles Sanders Peirce made major advances in semiotics, so he can act as a pipeline for these forgotten ideas. Most philosophers know Peirce as the founder of American pragmatism, but few know that he also coined the term “qualia,” which is meant to capture the intrinsic feel of an experience. Since pragmatic verification and qualia are now seen as conflicting commitments, Champagne endeavors to understand how Peirce could (or thought he could) have it both ways. The key, he suggests, is to understand how humans can insert distinctions between features that are always bound. Recent attempts to take qualities seriously have resulted in versions of panpsychism, but Champagne outlines a more plausible way to achieve this. So, while semiotics has until now been the least known branch of philosophy ending in –ics, his book shows how a better understanding of that branch can move one of the liveliest debates in philosophy forward.

Knowledge of what it’s like to have perceptual experiences, e.g. of what it’s like to see red or taste Turkish coffee, is phenomenal knowledge; and it is knowledge the substantial or significant nature of which is widely assumed to pose a challenge for physicalism. Call this the New Challenge to physicalism. The goal of this paper is to take a closer look at the New Challenge. I show, first, that it is surprisingly difficult to spell out clearly and neutrally what (...) the New Challenge is in fact urging the physicalist to explain. What initially look like plausible or promising ways of making sense of it turn out to be either question begging or insufficient to generate a challenge to physicalism at all. I go on to suggest that what the New Challenge may be asking the physicalist to explain may be the fact that we come to token certain higher-order judgments about the significance of phenomenal knowledge. I end with a discussion of the implications of this interpretation of the New Challenge—which turns out to be as much a challenge for the anti-physicalist as it is for the physicalist. (shrink)

Using his two-dimensional semantics, I demonstrate that David Chalmers’s 2010 ‘two-dimensional argument against materialism’ is sound only if a wide swath of reductive physicalist theses – crucially, those involving identity and other intrinsic reductive relations – are inconceivable. 2DA therefore begs the question against its opponents and undermines its argumentative relevance. Comparisons are drawn to similar arguments in Marton and Sturgeon; the present account differs in its formal and philosophical simplicity, as well as its specific application to reductivist doctrines beyond (...) the ineffective and merely supervenient.

Discussion of the challenge that acquaintance with the nature of experience poses to physicalism.

Defenders of the phenomenal concept strategy have to explain how both physical and phenomenal concepts provide a substantive grasp on the nature of their referents, whilst referring to the very same experience. This is the ‘new challenge’ to physicalism. In this paper, I argue that if the physicalist adopts the powerful qualities ontology of properties then a new and powerful version of the phenomenal concept strategy can be developed, which answers the new challenge.

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

The ontology of ‘powerful qualities’ is gaining an increasing amount of attention in the literature on properties. This is the view that the so-called categorical or qualitative properties are identical with ‘dispositional’ properties. The position is associated with C.B. Martin, John Heil, Galen Strawson and Jonathan Jacobs. Robert Schroer ( 2012 ) has recently mounted a number of criticisms against the powerful qualities view as conceived by these main adherents, and has also advanced his own (radically different) version of the (...) view. In this paper I have three main aims: firstly, I shall defend the ontology from his critique, arguing that his criticisms do not damage the position. Secondly, I shall argue that Schroer’s own version of the view is untenable. Thirdly, the paper shall serve to clear up some conceptual confusions that often bedevil the powerful qualities view.

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

In this paper, I offer a third way in debates over the scope of phenomenal consciousness, in the form of a novel synthesis of liberal and conservative introspective observations. My primary claim i...

Alleged self-evidence aside, conceivability arguments are one of the main reasons in favor of the claim that there is a Hard Problem. These arguments depend on the appealing Kripkean intuition that there is no difference between appearances and reality in the case of consciousness. I will argue that this intuition rests on overlooking a distinction between cognitive access and consciousness, which has received recently important empirical support. I will show that there are good reasons to believe that the intuition is (...) misguided—at least on the reading that the conceivability arguments require—and hence that the arguments are unsupported. This, in turn, alleviates the Hard Problem but leaves us with what I think is a not easy problem. (shrink)

Aesthetic concepts and conceptions are structured mental representations partly composed of phenomenal concepts. I defend this claim by appealing to contemporary accounts of concepts and to the current literature on phenomenal concepts. In addition, I discuss the relationship between aesthetic concepts and aesthetic understanding — an epistemic state at the centre of much work in contemporary epistemology.

David Lewis—famously—never tasted vegemite. Did he have any knowledge of what it's like to taste vegemite? Most say 'no'; I say 'yes'. I argue that knowledge of what it’s like varies along a spectrum from more exact to more approximate, and that phenomenal concepts vary along a spectrum in how precisely they characterize what it’s like to undergo their target experiences. This degreed picture contrasts with the standard all-or-nothing picture, where phenomenal concepts and phenomenal knowledge lack any such degreed structure. (...) I motivate the degreed picture by appeal to (1) limits in epistemic abilities such as recognition, imagination, and inference, and (2) the semantics of ‘knows what it’s like’ expressions. I argue that approximate phenomenal knowledge cannot be explained merely via determinable or vague phenomenal concepts. I develop a framework for systematizing approximate knowledge of phenomenal character. And I explain how my view challenges some standard assumptions about the acquisition conditions, requirements for mastery, and referential mechanisms of phenomenal concepts. (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)

A popular defense of physicalist theories of consciousness against anti-physicalist arguments invokes the existence of ‘phenomenal concepts’. These are concepts that designate conscious experiences from a first person perspective, and hence differ from physicalistic concepts; but not in a way that precludes co-referentiality with them. On one version of this strategy phenomenal concepts are seen as (1) type demonstratives that have (2) no mode of presentation. However, 2 is possible without 1-call this the ‘bare recognitional concept’ view-and I will argue (...) that this avoids certain recent criticisms while retaining the virtue of finessing the ‘mode of presentation’ problem for phenomenal concepts. But construing phenomenal concepts this way seems to not do justice to the phenomenology of conscious experience. In this paper I examine whether or not this impression can be borne out by a good argument. As it turns out, it is harder to do so than one might think. It can be done, but it involves somewhat more convoluted reasoning than one might have supposed necessary. Having shown that, I will end with a few brief remarks on what my argument means for attempts to preserve a physicalist account of consciousness. (shrink)

The aim of this paper is to reinforce anti-physicalism by extending the hard problem to a specific kind of intentional states. For reaching this target, I investigate the mental content of the new intentional states of Jackson’s Mary. I proceed in the following way: I start analyzing the knowledge argument, which highlights the hard problem tied to phenomenal consciousness. In a second step, I investigate a powerful physicalist reply to this argument: the phenomenal concept strategy. In a third step, I (...) propose a constitutional account of phenomenal concepts that captures the Mary scenario adequately, but implies anti-physicalist referents. In a last step, I point at the ramifications constitutional phenomenal concepts have on the constitution of Mary’s new intentional states. Therefore, by focusing the attention on phenomenal concepts, the so-called hard problem of consciousness will be carried over to the alleged easy problem of intentional states as well. (shrink)

This paper makes and defends four interrelated claims. First: most conscious experiences are complex in the sense that they have discernible constituent structure with discernible parts that can feature as parts of other experiences, and might occur as standalone experiences. Second: complex experiences have simple constituents that have no further discernible parts. Third: the phenomenal quality of having a complex experience is jointly determined by the phenomenal quality of its simple constituents plus the phenomenal structure simple constituents are organised into. (...) And fourth: physical descriptions can convey all the relevant information about the discernible phenomenal structure of conscious experiences. The combination of these four claims tells us that there is no further explanatory gap related to the phenomenal quality of complex experiences given that one is familiar with the phenomenal qualities of the simple parts constituting the complex experience in question, and that it is possible to acquire knowledge about the phenomenal quality of yet unexperienced complex experiences on the basis of previous acquaintances with constituent parts plus structural information. That is, the paper argues for a ‘summation’ model of phenomenal qualities. (shrink)

The phenomenal character of conscious experience has long been regarded as the major problem for physicalist accounts of consciousness. In recent years, defenders of physicalism have typically been relying on the so-called Phenomenal Concept Strategy to avoid dualism. In this paper, we argue with PCS that cognitive-physicalistic explanations can account for the peculiarities of phenomenal character. However, we think that the conceptual features PCS investigates are not the genuine causes of the special characteristics of phenomenal consciousness but only symptoms, which (...) can themselves be explained in terms of the features of the sensory-perceptual representations underlying conscious experiences, namely that some, but not all, of these states are representationally unstructured.

The aim of this paper is to critically assess and respond to two objections advanced by Daniel Stoljar against the so-called phenomenal concept strategy. My goal is to defend the physicalist response to both the knowledge argument and the conceivability argument against Stoljar’s objections. Regarding the conceivability argument, I want to show that the distinction mobilized by Stoljar between a priori and a priori synthesizable does not help us to elucidate the psychophysical condition for that is a clear disanalogy between (...) the cases presented by Stoljar. Regarding the knowledge argument, I want to show that Stoljar’s argument about experienced Mary undermines the fundamental premise of the knowledge argument and therefore it cannot be mobilized to deflate the phenomenal concept strategy against the knowledge argument. My conclusion will be that Stoljar’s points are ineffective against the phenomenal concept strategy. (shrink)

In metaphysics, there are a number of distinct but related questions about the existence of “further facts”—facts that are contingent relative to the physical structure of the universe. These include further facts about qualia, personal identity, and time. In this article I provide a sequence of examples involving computer simulations, ranging from one in which the protagonist can clearly conclude such further facts exist to one that describes our own condition. This raises the question of where along the sequence the (...) protagonist stops being able to soundly conclude that further facts exist. (shrink)

This paper suggests that reference to phenomenal qualities is best understood as involving iconicity, that is, a passage from sign-vehicle to object that exploits a similarity between the two. This contrasts with a version of the ‘phenomenal concept strategy’ that takes indexicality to be central. However, since it is doubtful that phenomenal qualities are capable of causally interacting with anything, indexical reference seems inappropriate. While a theorist like David Papineau is independently coming to something akin to iconicity, I think some (...) of the awkwardness that plagues his account would be remedied by transitioning to a more inclusive philosophy of signs.

In recent literature, there is a strong tendency to endorse the following argument: There are particular judgments about one's current phenomenal experiences that are infallible; if there are particular judgments about one's current phenomenal experiences that are infallible, then the infallibility of those judgments is due to the relation of acquaintance; therefore, acquaintance explains why those particular judgments about one's current phenomenal experiences are infallible. The aim of this paper is to examine critically both the first and the second premise (...) of this argument. It will emerge that there might be a small class of judgments about one's current phenomenal experiences that are infallible, namely judgments involving direct phenomenal concepts. However, as I will try to show, the infallibility of such judgments, if existent at all, is not due to the relation of acquaintance. (shrink)

In this paper, I examine the relationship between physicalism and property dualism in the light of the dialectic between anti-physicalist arguments and physicalist responses. Upon rehearsing the moves of each side, it is hard not to notice that there is a puzzling symmetry between dualist attacks on physicalism and physicalist replies. Each position can be developed in a way to defend itself from attacks from the other position, and it seems that there are neither a priori nor a posteriori grounds (...) to choose between the two. I suggest that the reason for the intractability of the disagreement, perhaps surprisingly, is they are both true: physicalism and dualism are formulated in terms of different conceptual schemes, each involving basic metaphysical concepts such as possibility, necessity, law and property. My proposal is that this means that there is no real disagreement in fact; both schemes get at the same reality, in different ways. -/- . (shrink)

The phenomenal concept strategy is considered a powerful response to anti-physicalist arguments. This physicalist strategy aims to provide a satisfactory account of dualist intuitions without being committed to ontological dualist conclusions. In this paper I first argue that physicalist accounts of phenomenal concepts fail to explain their cognitive role. Second, I develop an encapsulation account of phenomenal concepts that best explains their particularities. Finally, I argue that the encapsulation account, which features self-representing experiences, implies non-physical referents. Therefore, the account of (...) phenomenal concepts that has strong explanatory power does not explain away dualist intuitions—rather, it reinforces dualism. (shrink)

When asked which of our concepts are normative concepts, metaethicists would be quick to list such concepts as GOOD, OUGHT, and REASON. When asked why such concepts belong on the list, metaethicists would be much slower to respond. Matti Eklund is a notable exception. In his recent book, Choosing Normative Concepts, Eklund argues by elimination for “the Normative Role view” that normative concepts are normative in virtue of having a “normative role” or being “used normatively”. One view that Eklund aims (...) to eliminate is “the Metaphysical view” that normative concepts are normative in virtue of referring to normative properties. In addition to arguing that Eklund’s objection looks doubtful by its own lights, we argue that there are several plausible versions of the Metaphysical view that Eklund doesn’t eliminate, defending various claims about normative concepts and their relationships to deliberation, competence, reference, and possession along the way.

This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- (...) which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne. (shrink)

Is it possible to build a conscious machine, an artifact that has qualitative experiences such as feeling pain, seeing the redness of a flower or enjoying the taste of coffee ? What makes such experiences conscious is their phenomenal character: it is like something to have such experiences. In contemporary philosophy of mind, the question of the qualitative aspect of conscious experiences is often addressed in terms of qualia. In a pre-theoretical and intuitive sense, qualia refer to the phenomenal character (...) or “what-it’s-like-ness” of a conscious experience: the painfulness of a pain experience or the redness of a visual experience of a red object. The problem of artificial qualia is the question of the theoretical possibility of the realization of qualia by artifacts. In this work, this problem will serve as a methodological tool to address what is arguably the most fundamental question of philosophy of mind: what exactly is consciousness? (shrink)

Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

Llamamos “conocimiento fenoménico” al conocimiento de nuestras experiencias conscientes: al saber cómo es tener una determinada experiencia. Los conceptos fenoménicos son aquellos asociados a este conocimiento y refieren, de modo introspectivo y directo, a las propiedades fenoménicas de nuestras experiencias. El papel que juegan estos conceptos es esencial en la filosofía de la mente contemporánea en la medida que muchos de sus defensores creen que una explicación adecuada de su naturaleza nos permitirá disipar un sinfín de rompecabezas epistemológicos (sobre la (...) relación de los individuos con sus estados fenoménicos) y metafísicos (que giran en torno a la naturaleza de la consciencia). Estos problemas son dos caras de la misma moneda y una respuesta a uno conlleva, necesariamente, implicaciones para el otro. Mi objetivo en este artículo es ofrecer una introducción al papel que desempeñan los conceptos fenoménicos en el debate metafísico en torno a la naturaleza de la consciencia. En especial, esta exposición se centra en la Estrategia de los Conceptos Fenoménicos, una de las respuestas fisicistas a los argumentos dualistas cuya conclusión es que no es posible acomodar una explicación de la consciencia en un marco fisicista. Para ello, en §1 describo la tesis central del fisicismo y presento uno de los más célebres argumentos en su contra: el argumento del conocimiento. Enseguida, en §2 expongo qué son los conceptos fenoménicos y en qué difieren de otro tipo de conceptos, en §3 explico el modus operandi de la Estrategia de los Conceptos Fenoménicos en respuesta a los retos dualistas señalados en §1, y en §4 menciono algunas de las objeciones más frecuentes en contra de esta estrategia. Finalmente, en §5 hago una síntesis de los puntos esenciales discutidos en este artículo. (shrink)

In this paper it is argued that existing ‘self-representational’ theories of phenomenal consciousness do not adequately address the problem of higher-order misrepresentation. Drawing a page from the phenomenal concepts literature, a novel self-representational account is introduced that does. This is the quotational theory of phenomenal consciousness, according to which the higher-order component of a conscious state is constituted by the quotational component of a quotational phenomenal concept. According to the quotational theory of consciousness, phenomenal concepts help to account for the (...) very nature of phenomenally conscious states. Thus, the paper integrates two largely distinct explanatory projects in the field of consciousness studies: (i) the project of explaining how we think about our phenomenally conscious states, and (ii) the project of explaining what phenomenally conscious states are in the first place.

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)
