Phenomenal knowledge is knowledge of what it is like to be in conscious states, such as seeing red or being in pain. According to the knowledge argument (Jackson 1982, 1986), phenomenal knowledge is knowledge that, i.e., knowledge of phenomenal facts. According to the ability hypothesis (Nemirow 1979; Lewis 1983), phenomenal knowledge is mere practical knowledge how, i.e., the mere possession of abilities. However, some phenomenal knowledge also (...) seems to be knowledge why, i.e., knowledge of explanatory facts. For example, someone who has just experienced pain for the first time learns not only that this is what pain is like, but also why people tend to avoid it. Some philosophers have claimed that experiencing pain gives knowledge why in a normative sense: it tells us why pain is bad and why inflicting it is wrong (Kahane 2010). But phenomenal knowledge seems to explain not (only) why people should avoid pain, but why they in fact tend to do so. In this paper, I will explicate and defend a precise version of this claim and use it as a basis for a new version of the knowledge argument, which I call the explanatory knowledge argument. According to the argument, some phenomenal knowledge (1) explains regularities in a distinctive, ultimate or regress-ending way, and (2) predict them without induction. No physical knowledge explains and predicts regularities in the same way. This implies the existence of distinctive, phenomenal explanatory facts, which cannot be identified with physical facts. I will show that this argument can be defended against the main objections to the original knowledge argument, the ability hypothesis and the phenomenal concept strategy, even if it turns out that the original cannot. In this way, the explanatory knowledge argument further strengthens the case against physicalism. (shrink)

: Phenomenal knowledge usually comes from experience. But it need not. For example, one could know what it’s like to see red without seeing red—indeed, without having any color experiences. Daniel Dennett (2007) and Pete Mandik (forthcoming) argue that this and related considerations undermine the knowledge argument against physicalism. If they are right, then this is not only a problem for anti‐physicalists. Their argument threatens to undermine any version of phenomenal realism— the view that there are (...) phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties. I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. This will strengthen the case for physically and functionally irreducible qualia. 2 Phenomenal knowledge usually comes from experience. For example, I know what it’s like to see red because I have done so. Does knowing what it’s like to have an experience with phenomenal character X require having an experience with X? No. A famous counterexample is Hume’s missing shade of blue, in which one can extrapolate from phenomenally similar experiences (A Treatise of Human Nature, Bk. I, Pt. I, Sec. I).1 One might think that a weaker version of the no‐phenomenal‐knowledge‐without‐experience thesis remains tenable, e.g., that knowing what it’s like to see in color requires having or having had color experiences. But this thesis also seems doubtful. Peter Unger (1966) devised plausible counterexamples over four decades ago, and since then others (e.g., Lewis 1988, Alter 1998, Stoljar 2005) have done the same. One could have phenomenal knowledge of color experiences without having such experiences. Indeed, one could have such knowledge without having experiences that are remotely like color experiences. What is the significance of this observation for contemporary debates about consciousness and physicalism? Daniel Dennett (2007) and Pete Mandik (forthcoming) suggest that it undermines the knowledge argument against physicalism.2 That is because they take the claim that someone who has never seen in color could not know what it’s like to see in color to be the basis of the knowledge argument’s main epistemic premise: the premise that (roughly put) 3 no amount of physical knowledge is sufficient for phenomenal knowledge of color experiences. If they are right, then this is not only a problem for anti‐ physicalists. Many physicalists (e.g., Loar 1990/97, Papineau 2002, 2007) accept the knowledge argument’s epistemic premise. Dennett’s and Mandik’s arguments threaten all versions of what David Chalmers (2003) calls phenomenal realism, the view that there are phenomenal properties, or qualia, that are not conceptually reducible to physical or functional properties.3 I will argue that this threat is illusory. Explaining why will clarify what is and is not at issue in discussions of the knowledge argument and phenomenal realism. The net result will be to strengthen the case for physically inexplicable qualia. (shrink)

In this paper, I analyze the role of phenomenal knowledge in understanding the experiences of the victims of hermeneutical injustice. In particular, I argue that understanding that is enriched by phenomenal knowledge is a powerful tool to mitigate hermeneutical injustice. I proceed as follows: Firstly, I investigate the requirements for a full understanding of the experiences at the center of hermeneutical injustice and I argue that phenomenal knowledge is key to full understanding. Secondly, I (...) distinguish between direct phenomenal knowledge and imaginative phenomenal knowledge. Thirdly, I investigate whether one can gain imaginative phenomenal knowledge of the experiences of members of social groups other than one´s own. I consider reasons for pessimism in this regard and show that they are not conclusive. Then, I provide a model of how outgroup members can acquire imaginative knowledge of the experiences of the victims of hermeneutical injustice. Finally, I connect the varieties of phenomenal knowledge with different grades of understanding an experience and I outline how understanding that involves imaginative phenomenal knowledge helps to overcome various forms of hermeneutical injustice.

Deviant phenomenal knowledge is knowing what it’s like to have experiences of, e.g., red without actually having had experiences of red. Such a knower is a deviant. Some physicalists have argued and some anti-physicalists have denied that the possibility of deviants undermines anti-physicalism and the Knowledge Argument. The current paper presents new arguments defending the deviant-based attacks on anti-physicalism. Central to my arguments are considerations concerning the psychosemantic underpinnings of deviant phenomenal knowledge. I argue that (...) physicalists are in a superior position to account for the conditions in virtue of which states of deviants constitute representations of phenomenal facts. (shrink)

In some philosophical arguments an important role is played by the claim that certain situations differ from each other with respect to phenomenology. One class of such arguments are minimal pair arguments. These have been used to argue that there is cognitive phenomenology, that high-level properties are represented in perceptual experience, that understanding has phenomenology, and more. I argue that facts about our mental lives systematically block such arguments, reply to a range of objections, and apply my critique to some (...) examples from the literature. (shrink)

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)

This paper is a defense of the so-called phenomenal-concept strategy, based on a new view of phenomenal concepts as special de re modes of presentation of the phenomenal character of experience. Phenomenal concepts can be explained in physical terms as mental particulars (as phenomenal files) created in the individual’s mind to pick out the phenomenal character of experience by representing certain physical properties as those represented by the experiences themselves (metarepresentation). They are individuated by (...) two fundamental relations: the perceptual (acquaintance) relation the creature bears to the physical properties represented by its own experience and the relation the creature bears to itself (self-acquaintance) as the subject undergoing those experiences. Mary’s newly acquired phenomenal file presents the phenomenal character of her new experience of red by means of the new relation she bears to herself as the creature standing in the experiential relation to the color red.

The irreducibility thesis of phenomenal consciousness can only succeed against the sceptical attack and avoid solipsism iff it can coherently establish the transition from subjective certainty to the objectivity of knowledge. The sceptical attack on the relationship between the phenomenal qualitative character of experience about the subjects own mental fact and the awareness of the qualitative properties of the phenomenal object can be avoided through establishing the immediacy of experience. The phenomenal realist become successful in (...) establishing the subjective certainty about the knowledge of phenomenal consciousness, however, has been failed in establishing objective certainty of knowledge, which leads to several epistemological problems (i.e., scepticism about the independent existence of external world, knowledge about the external reality and the existence of other mind; popularly known as the harder problem of consciousness) in philosophy of mind. In this paper, my objective is to reveal the undesirable consequences of representationalism. Representationalism is not an ideal option for responding to the sceptical attack against the other minds and the reality of the external world. It always leaves an open question for us about the relation between the representation of the object of experience and consciousness. Representationalistic theories of experience violates the principles of phenomenality by rejecting the immediacy of experience and has been committing the pragmatic contradiction by reducing the phenomenal properties to representational properties. The categorization of knowledge about phenomenality as inferential knowledge by representationalist leave no room for foundational knowledge about phenomenality. (shrink)

Some analytic philosophers have recently been defending the thesis that there’s “something it’s like” to consciously think a particular thought, which is qualitatively different from what it’s like to be in any other kind of conscious mental state and from what it’s like to think any other thought, and which constitutes the thought’s intentional content. (I call this the “intentional phenomenology thesis”). One objection to this thesis concerns the introspective availability of such content: If it is true that intentional phenomenology (...) is constitutive of intentional content, and that conscious phenomenology is always introspectively available, then it ought to be true that the content of any concept consciously entertained is always introspectively available. But it is not. For example, one can know introspectively that one is thinking that one knows that p without knowing introspectively what the content of the concept of knowledge is. Hence, it cannot be that intentional content is constituted by cognitive phenomenology. -/- I explore three responses to this objection. First, it is not clear that all of the contents of consciousness must be equally available to introspection. The capacities for conscious experience and introspective attention to it are distinct. It is not implausible that the resolving power of the latter might be insufficient to discern all of the fine-grained details of the former, or that its scope might be limited. Second, it is possible that in cases of incomplete accessibility one is entertaining only part of the concept the relevant term expresses in one’s language. In the knowledge case, for example, perhaps one is thinking only that one has justified true belief that p (one’s self-attribution of a thought about knowledge is in fact false). Finally, in such cases one might be consciously entertaining only part of the relevant concept, the rest remaining unconscious, and so unavailable to conscious introspection. I conclude that the objection is not decisive against the intentional phenomenology thesis. (shrink)

In this chapter, we argue for a phenomenal conservative perspective on religious epistemology and attempt to answer some common criticisms of this perspective.

Introspective knowledge by acquaintance is knowledge we have by being directly aware of our phenomenally conscious states. In this paper, I argue that introspective knowledge by acquaintance is a sui generis kind of knowledge: it is irreducible to any sort of propositional knowledge and is wholly constituted by a relationship of introspective acquaintance. My main argument is that this is the best explanation of some epistemic facts about phenomenal consciousness and introspection. In particular, it (...) best explains the epistemic asymmetry between a subject who has never had a certain phenomenal state and one who has. I also consider two theoretical objections to my claim: an objection from disunity and an objection from mysteriousness. I show that these objections can be answered and that introspective knowledge by acquaintance being sui generis remains a live option on the table. (shrink)

Some contemporary discussion about the explanation of consciousness substantially recapitulates a decisive debate about reference, knowledge and justification from an earlier stage of the analytic tradition. In particular, I argue that proponents of a recently popular strategy for accounting for an explanatory gap between physical and phenomenal facts – the so-called “phenomenal concept strategy” – face a problem that was originally fiercely debated by Schlick, Carnap, and Neurath. The question that is common to both the older and (...) the contemporary discussion is that of how the presence or presentation of phenomenal experiences can play a role in justifying beliefs or judgments about them. This problem is, moreover, the same as what was classically discussed as the problem of acquaintance. Interestingly, both physicalist and non-physicalist proponents of the phenomenal concept strategy today face this problem. I consider briefly some recent attempts to solve it and conclude that, although it is prima facie very plausible that acquaintance exists, we have, as yet, no good account of it. (shrink)

In the philosophical literature on mental states, the paradigmatic examples of mental states are beliefs, desires, intentions, and phenomenal states such as being in pain. The corresponding list in the psychological literature on mental state attribution includes one further member: the state of knowledge. This article examines the reasons why developmental, comparative and social psychologists have classified knowledge as a mental state, while most recent philosophers--with the notable exception of Timothy Williamson-- have not. The disagreement is traced (...) back to a difference in how each side understands the relationship between the concepts of knowledge and belief, concepts which are understood in both disciplines to be closely linked. Psychologists and philosophers other than Williamson have generally have disagreed about which of the pair is prior and which is derivative. The rival claims of priority are examined both in the light of philosophical arguments by Williamson and others, and in the light of empirical work on mental state attribution. (shrink)

In response to Petitmengin and Bitbol's recent account of first-person methodologies in the study of consciousness, I provide a revised model of our introspective knowledge of our own conscious experience. This model, which I call the existential constitution model of phenomenal knowledge, avoids the problems that Petitmengin and Bitbol identify with standard observational models of introspection while also avoiding an underlying metaphorical misconception in their own proximity model, which misconstrues first-person knowledge of consciousness in terms of (...) a dichotomous epistemic relationship. The end result is a clearer understanding of the unique nature and epistemic properties of our knowledge of consciousness, as well as the epistemic status of subsequent first-person reports on conscious experience.

We critique MacIntyre's traditions-based perspectivalist approach to religious epistemology as articulated by Erik Baldwin from the perspective of phenomenal conservatism.

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal (...) concepts. My arguments exploit the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails. (shrink)

Frank Jackson’s knowledge argument and different conceivability arguments, advanced by Saul Kripke, David Chalmers and Joseph Levine, conclude that consciousness involves non-physical properties or properties that cannot be reductively accounted for in physical terms. Some physicalists have replied to these objections by means of different versions of the phenomenal concept strategy. David Chalmers has responded with the master argument, a reasoning that, if successful, would undermine any reasonable version of the phenomenal concept strategy. In this paper, I (...) argue that the master argument does not advance the debate between the supporters of the anti-physicalist arguments and those of the phenomenal concept strategy. (shrink)

Philosophers and scientists refer to the special character of phenomenal consciousness, something supposedly obvious to all conscious persons. However, we had no empirical evidence about the folk view of consciousness until the first studies were carried out in the experimental philosophy of consciousness. According to the leading interpretation of these results, laypersons—people without academic knowledge about consciousness—do not notice the phenomenal aspect of consciousness. The aim of the article is to answer the question of whether we can (...) trust these results. I show that there are serious doubts about the validity of the experimental philosophy of consciousness research. As a result, the leading interpretation should be rejected, and the question about the folk nature of the concept of consciousness must be regarded as open. (shrink)

In my article I reconstruct the main threads of Robert Stalnaker’s book Our Knowledge of the Internal World, which focuses on the problem of our epistemic relation to our experience and the relation between experience and knowledge. First, the book proposes an interesting view of externalism, which combines classical externalist claims with a contextualist approach to content ascriptions. The approach accommodates some important internalist intuitions by showing how content ascriptions can be sensitive to the perspective from which a (...) subject perceives the world. Second, Stalnaker proposes a theory of selflocating and phenomenal knowledge, which should be understood in terms of differentiating between real possibilities. The puzzling upshot of this elegant solution is that it commits one to the existence of possibilities accessible only from the first-person perspective. Finally, Stalnaker presents an argument which shows that our knowledge about our phenomenal experience is no more direct than the knowledge about external objects. Stalnaker’s claim that by merely having an experience we don’t learn any new information seems, however, too strict in light of his contextualist approach to content ascriptions. (shrink)

Epiphenomenalist dualists hold that certain physical states give rise to non-physical conscious experiences, but that these non-physical experiences are themselves causally inefficacious. Among the most pressing challenges facing epiphenomenalists is the so-called “paradox of phenomenal judgment”, which challenges epiphenomenalism’s ability to account for our knowledge of our own conscious experiences. According to this objection, we lack knowledge of the very thing that epiphenomenalists take physicalists to be unable to explain. By developing an epiphenomenalist theory of subjects and (...) mental states, this paper argues that there is nothing paradoxical or problematic about the epiphenomenalist’s understanding of phenomenal judgments or phenomenal self-knowledge. The appearance of paradox emerges from inconsistently combining (epiphenomenalist) dualism about qualia with a physicalistic conception of subjects of experience. The lesson we should take from this is not that there is anything wrong with epiphenomenalism, but that epiphenomenalist dualists should be “dualists all the way down”—embracing a picture of mind that gives phenomenology a central place, in its understanding of both subjects and their knowledge of their own minds. Epiphenomenalist-friendly accounts of reference and memory are also developed, showing that neither of these issues creates a paradox for the epiphenomenalist. (shrink)

It may be true that we are epistemically in the dark about various things. Does this fact ground the truth of fallibilism? No. Still, even the most zealous skeptic will probably grant that it is not clear that one can be incognizant of their own occurrent phenomenal conscious mental goings-on. Even so, this does not entail infallibilism. Philosophers who argue that occurrent conscious experiences play an important epistemic role in the justification of introspective knowledge assume that there are (...) occurrent beliefs. But this assumption is false. This paper argues that there are no occurrent beliefs. And it considers the epistemic consequences this result has for views that attempt to show that at least some phenomenal beliefs are infallible. (shrink)

This paper explores the logical consequences of the the thesis that all of the essential properties of consciousness can be known introspectively (Completeness, called "Strong Transparency" in the paper, following D.M. Armstrong's older terminology). It is argued that it can be known introspectively that consciousness does not have complete access to its essential properties; and it is show how this undermines conceivability arguments for dualism.

If I am aware that p, say, that it is raining, is it the case that I must be aware that I am aware that p? Does introspective or object-awareness entail the apprehension of mental states as being of some kind or another: self-monitoring or intentional? That is, are cognitive events implicitly self-aware or is “self-awareness” just another term for metacognition? Not surprisingly, intuitions on the matter vary widely. This paper proposes a novel solution to this classical debate by reframing (...) the problem of self-knowledge in terms of the relation between phenomenal concepts and phenomenal knowledge. Concepts of consciousness such as “introspective awareness” and “reflexive self-awareness” are grounded in phenomenal experiences rather than physical events and processes. As such they yield a different kind of self-knowledge than what can be gained by applying externalist conceptual schemas to understanding the mind. I argue that Dharmakīrti’s theory of content can be seen as endorsing the efficacy of phenomenal experience as a vehicle for self-knowledge. (shrink)

This work examines and critically evaluates the proposal that phenomenal properties, or the subjective qualities of experience, present a formidable challenge for the mind-body identity theory. Physicalism per se is construed as being ontically committed only to phenomena which can be made epistemically and cognitively available in the third person; observed and understood from within an objective frame of reference. Further, the identity relation between the mental and the physical is taken to be strict identity; the mental phenomena in (...) question just are the physical phenomena on which, ex hypothesi, they supervene. The problem of phenomenal properties has two basic strands. The first is the problem of how they are causally related to the physical; if they are not physical phenomena, by what causal mechanism might they be related to physical phenomena? One of the motivating considerations which led to the identity thesis was that it appeared to remove this problem. Our interest, however, is in evaluating the arguments which purport to establish that phenomenal properties are, indeed, distinct from the physical. (shrink)

Standard responses to the knowledge argument grant that Mary could know all of the physical facts even while trapped inside her black‐and‐white room. What they deny is that upon leaving her black‐and‐white room and experiencing red for the first time, Mary learns a genuinely new fact. This paper develops an alternate response in a grounding physicalist framework, on which Mary does not know all of the physical facts while trapped inside the room. The main thesis is that Mary does (...) not know certain phenomenal facts while trapped inside the room, whereby these facts classify as physical due to being wholly and fully metaphysically grounded in the underlying fundamental facts which are themselves entirely physical.

Over the past decade or so, David Papineau has given an account of the content and motivation of a physicalist conception of the world with more thoroughness and argumentative defence than many physicalists have thought necessary. In doing this, he has substantially advanced the debate on physicalism, and physicalists and non-physicalists alike should be grateful to him.1 At the heart of Papineau’s defence of physicalism in his recent book (2002) is his theory of phenomenal concepts. Like many physicalists, Papineau (...) diagnoses the apparent threats to physicalism posed by the phenomena of consciousness by locating the source of anti-physicalist intuitions in features of our thinking rather than in non-physical features of reality. But what is new in Thinking About Consciousness is his detailed account of which features of our thinking it is that generate these supposedly confused anti-physicalist arguments. Hence the bulk of the book is an attempt to show that the most famous ‘consciousness-based’ anti-physicalist arguments—the knowledge argument, the zombie argument and the explanatory gap argument—rest on a mistaken understanding of certain kinds of concepts: phenomenal concepts. I agree with Papineau that physicalism (properly understood) should not be troubled by the knowledge argument and the explanatory gap argument, and that some other anti-physicalist arguments seem to move from assumptions about ways of thinking to conclusions about reality. But I doubt whether his theory of phenomenal concepts can help his defence of physicalism and his diagnosis of the errors of dualism. My reason for saying this is that I do not think there are any such concepts. In saying this I do not mean to deny that there is a useful distinction to be made between scientific concepts, the mastery of which requires knowledge of a certain amount of theory, and concepts which are acquired on the basis of experience, which can be called ‘phenomenal’ concepts.

Plantinga develops an ambitious theistic religious epistemology on which theists can have non-inferential knowledge of God. Central to his epistemology is the idea that human beings have a “sensus divinitatis” that produces such knowledge. Recently, several authors have urged an appropriation of the sensus divinitatis that is more friendly to internalist views, such as Phenomenal Conservativism. I argue that this appropriation is too timid and tepid in a variety of ways. It applies only to a small fraction (...) of theistic beliefs; it fails to play the theological role Plantinga intended the sensus divinitatis to play; it fails to imply that most theistic beliefs, most of the time, are justified; when combined with a standard form of Evidentialism, it actually implies that most theistic beliefs are, if justified, inferentially justified; and it is consistent with substantive criticisms of theistic belief originating in work from the Cognitive Science of Religion.

This paper is a new defense of type-B materialism against Jackson’s knowledge argument (1982) inspired by the Kantian main opposition between concepts and sensible intuitions. Like all materialists of type B, I argue that on her release from her black-and-white room, Mary makes cognitive progress. However, contrary to the so-called phenomenal concept strategy (henceforth PCS), I do not think that such progress can be accounted for in terms of the acquisition of new concepts. I also reject Tye’s recent (...) account of Mary’s cognitive progress as the acquisition of a “thing-knowledge.” What is crucial is not the Russellian opposition between knowing things and knowing truths but rather the Kantian opposition between conceptual and nonconceptual representations of the same thing (property). Mary’s phenomenal knowledge is here accounted for as the result of the cooperation of her newly acquired nonconceptual representation of the same phenomenal redness (the same thing) she had a conceptual representation before. As that new nonconceptual representation carries information about the same physical property she already represented but is now coded in analog rather than in digital form (Dretske, 1981), that nonconceptual representation can be accounted for in physical terms as Chalmers’s Master argument requires. Nevertheless, that representation can account for Mary’s cognitive progress since it carries information coded in analog form, something that the imprisoned she could never possess. (shrink)

This chapter focuses on the relationship between consciousness and knowledge, and in particular on the role perceptual consciousness might play in justifying beliefs about the external world. We outline a version of phenomenal dogmatism according to which perceptual experiences immediately, prima facie justify certain select parts of their content, and do so in virtue of their having a distinctive phenomenology with respect to those contents. Along the way we take up various issues in connection with this core theme, (...) including the possibility of immediate justification, the dispute between representational and relational views of perception, the epistemic significance of cognitive penetration, the question of whether perceptual experiences are composed of more basic sensations and seemings, and questions about the existence and epistemic significance of high-level content. In a concluding section we briefly consider how some of the topics pursued here might generalize beyond perception. (shrink)

Jackson (1982) introduced the Knowledge Argument to elucidate the phenomenal, interior aspects of experience. In 1908 McTaggart defined two series that characterize one dimension of time, the A-series and the B-series. The A-series is usually thought to be phenomenal Farr (2019), SEP (2018). Thus there is the possibility of giving a Knowledge Argument for time. One (informal) statement of the classical Knowledge Argument might be “Mary knows all the facts about color qualia but lives in (...) a black-and-white room. Upon being released into a colorful world, it would seem she learns something new.” The analogous Knowledge Argument for Time (KAT) would be “Nathan knows all the facts about time but lives in a B-series room. Upon being released into a world with both an A-series and a B-series it would seem he learns something new.” I give variations of the KAT based on various distinctions. I don’t give any particular proposed solutions to the Knowledge Arguments for Time. Rather, the point is to state the Arguments (or indicate how they may be stated). It may be hoped that these will help clarify some issues in the philosophy of time and lead to a cross-fertilization between the philosophy of time and the philosophy of mind. (shrink)

Quantities like mass and temperature are properties that come in degrees. And those degrees (e.g. 5 kg) are properties that are called the magnitudes of the quantities. Some philosophers (e.g., Byrne 2003; Byrne & Hilbert 2003; Schroer 2010) talk about magnitudes of phenomenal qualities as if some of our phenomenal qualities are quantities. The goal of this essay is to explore the anti-physicalist implication of this apparently innocent way of conceptualizing phenomenal quantities. I will first argue for (...) a metaphysical thesis about the nature of magnitudes based on Yablo’s proportionality requirement of causation. Then, I will show that, if some phenomenal qualities are indeed quantities, there can be no demonstrative concepts about some of our phenomenal feelings. That presents a significant restriction on the way physicalists can account for the epistemic gap between the phenomenal and the physical. I’ll illustrate the restriction by showing how that rules out a popular physicalist response to the Knowledge Argument. (shrink)

In 1982 Jackson introduced the Knowledge Argument to elucidate the phenomenal, interior aspects of experience.

Buridan holds that the proper subject of psychology (i.e., the science undertaken in Aristotle’s De Anima) is the soul, its powers, and characteristic functions. But, on his view, the science of psychology should not be understood as including the body nor even the soul-body composite as its proper subject. Rather its subject is just “the soul in itself and its powers and functions insofar as they stand on the side of the soul". Buridan takes it as obvious that, even thus (...) narrowly construed, such a science is possible. To the extent that this science includes the human or intellective soul, however, Buridan’s claim regarding its possibility is far from obvious. After all, like most of his contemporaries, Buridan takes the human soul to be immaterial. Thus, he readily admits that “the intellect cannot be sensed” and its operations are likewise inaccessible to the senses. Yet, on Buridan's broadly empiricist theory of knowledge, all (human) knowledge, including knowledge of the intellect or intellective soul, takes its start in the senses. How, then, is a science of the human soul possible? What is the nature or source of our knowledge of the intellect? In this paper, I reconstruct Buridan's answer to these questions. -/- My discussion divides roughly into two parts. In the first, I set out the main elements of Buridan’s account of how we come to cognize the intellect, focusing on what he says about the genesis of our concept of the intellect. I then consider his account of our cognition of our own intellective states. As the discussion in part one make clear, Buridan holds that our concepts of intellect and of intellective states are both derived (inferentially) from subjective “experience” of our own states and rational activities. In part two, therefore, I try to elucidate Buridan’s notion of experience. Ultimately, I argue that it is a non-conceptual, non-discursive mode of self-awareness. I suggest, moreover, that it might best be understood in terms of our own notion of phenomenal consciousness. On the interpretation I advance, then, it turns out that, for Buridan, our concept of the intellect itself and, hence, the science of (human) psychology in general, is ultimately grounded in phenomenal experience of our own intellective states.

Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge about experiences is not complete knowledge about experiences to the falsity of physicalism. Some physicalists (e.g., John Perry) have countered by arguing that what Jackson’s Mary, the perfect scientist who acquires all physical knowledge about experiencing red while being locked in a monochromatic room, lacks before experiencing red is merely a piece of recognitional knowledge of an identity, and that since lacking a (...) piece of recognitional knowledge of an identity does not entail lacking any pieces of knowledge of worldly facts, physicalism is safe. I will argue that what Mary lacks in her room is not merely a piece of recognitional knowledge of an identity and that some physicalists have failed to see this because of a failure to appreciate that Mary’s epistemic progress when she first experiences red has two different stages. While the second epistemic stage can perhaps be plausibly considered as acquiring merely a piece of recognitional knowledge of an identity, there is good reason to think that the first epistemic stage cannot be thus considered.

It is widely accepted that physicalism faces its most serious challenge when it comes to making room for the phenomenal character of psychological experience, its so-called what-it-is-like aspect. The challenge has surfaced repeatedly over the past two decades in a variety of forms. In a particularly striking one, Frank Jackson considers a situation in which Mary, a brilliant scientist who knows all the physical facts there are to know about psychological experience, has spent the whole of her life in (...) a black and white room. He asks, What will happen when Mary is released from her black and white room or is given a colour television monitor? Will she learn anything or not? It seems just obvious that she will learn something about the world and our visual experience of it. But then it is inescapable that her previous knowledge was incomplete. But she had all the physical information. (Jackson 1986: 130). (shrink)

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) (...) even granting (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

This paper is both systematic and historical in nature. From a historical viewpoint, I aim to show that to establish Wittgenstein’s claim that “an ‘inner process’ stands in need of outward criteria” (PI §580) there is an enthymeme in Wittgenstein’s private language argument (henceforth PLA) overlooked in the literature, namely Wittgenstein’s suggestion that both perceptual and bodily experiences are transparent in the relevant sense that one cannot point to a mental state and wonder “What is that?” From a systematic viewpoint, (...) I aim to show that Wittgenstein’s PLA teaches us that the prevailing picture of the nature of phenomenal concepts (henceforth PCs) is upside down: we can only introspectively know what is going on inside our heads after we learn of what is going on outside (PI §580). In this regard, I aim to defend two associate claims against the prevailing view of PCs on the basis of PLA. First, by means of transparency, I aim to show that there is no de re awareness of our private sensation that could determine the meaning of sensation words; for example, I am never aware of the phenomenal blueness of my experience of something blue. The second associated claim is that introspective self-knowledge of our private sensations is always de dicto. We can only know introspectively that phenomenal blueness is the phenomenal character of the experience we are undergoing after we have learned that (de dicto knowledge) blue is the color that usually causes us that kind of experience. Likewise, we can only introspectively know that pain is the phenomenal character of the experience we are undergoing after we have learned that pain is what usually causes some typical pain behavior.

One distinct interest in self-knowledge concerns whether one can know about one’s own mental states and processes, how much, and by what methods. One broad distinction is between accounts that centrally claim that we look inward for self-knowledge (introspective methods) and those that claim that we look outward for self-knowledge (transparency methods). It is here argued that neither method is sufficient, and that we see this as soon as we move beyond questions about knowledge of one’s (...) beliefs, focusing instead on how one distinguishes, for oneself, one’s veridical visual memories from mere (non-veridical) visual images. Given robust psychological and phenomenal similarities between episodic memories and mere imagery, the following is a genuine question that one might pose to oneself: “Do I actually remember that happening, or am I just imagining it?” After critical analysis of the transparency method (advocated by Byrne 2010, following Evans 1982) to this latter epistemological question, a brief sketch is offered of a more holistic and inferential method for acquisition of broader self-knowledge (broadly following the interpretive-sensory access account of Carruthers 2011). In a slogan, knowing more of the mind requires using more of the mind. (shrink)

This article presents phenomenological meta-analysis of Tymieniecka's phenomenology of life with regard to its strategies of knowledge. The novelty of phenomenology of life consists in special orientation of direct intuition of Tymieniecka's insight. The analysis suggests that the positioning of the direct intuition differes from philosopher to philosopher. Even though this perspective pays attention to individual differences in philosophical thinking, this view has to be distinguished froll1 psychologism as criticized by Husser!. and rather, seen as a development of Husserl (...) 's lheory of direct intuition. A framework for such analysis can be also found in Islamic philosophies of Suhrawardi and Ibn 'Arabi, who introduced the concepts of individual predisposition, modes of knowledge, and self-knowledge mediated by knowledge by presence. These concepts can be applied to understanding of the origins of philosophical insight. The paper examines in depth the workings of direct, or presentive, intuition in Tymieniecka's descriptions of the phenomenal field of life, and of life per se as a dynamic object. It demonstrates the dialogical nature of interrogation, and the sentience of logos as a horizon of philosophical inquiry. Finally, the paper introduces the concept of process phenomenology, and suggests directions of future research with regard to phenomenology of imagination. (shrink)

Epistemological contrastivism can model how infallible knowledge functions by employing the explanatory resource of structural differences between contrastive propositions, e.g., “P rather than Q”, and orthodox propositions, e.g., “P”. In doing so we notice that how this difference factors into our conception of infallible knowledge depends on two aspects: one, whether belief acts as a necessary condition for knowledge, and two, whether epistemic justification is construed as consciously internalist or non-consciously externalist. We further leverage the notion of (...) phenomenal resolution, conceived as an outcome of one’s discriminative capacities in accessing their evidence, to clarify in what sense it becomes reasonable to say that the truth of P mutually excludes the truth of Q when the latter is contrasted to the former. Importantly then, there is a way of infallibly knowing that P that is indistinguishable from infallibly knowing that P rather than Q, and a way that is not. (shrink)

This paper responds to critical commentaries on my book, Perceiving Reality (OUP, 2012), by Laura Guerrero, Matthew MacKenzie, and Anand Vaidya. Guerrero focuses on the metaphysics of causation, and its role in the broader question of whether the ‘two truths’ framework of Buddhist philosophy can be reconciled with the claim that science provides the best account of our experienced world. MacKenzie pursues two related questions: (i) Is reflexive awareness (svasaṃvedana) identical with the subjective pole of a dual-aspect cognition or are (...) there alternative, perhaps better, ways of understanding this self-intimating character of mental states? (ii) Is perception constitutively intentional or is it representational? Vaidya argues that, in so far as Husserlian phenomenology and Buddhism differ in terms of their fundamental ontological commit- ments, they must be incompatible, thus rendering any cross-cultural philosophical project that seeks their rapprochement tenuous. One of my aims in Perceiving Reality is to show how accounts of perception informed by metaphysical realism can be problematic on both metaphysical and epistemological grounds, especially when relying on conceptions of consciousness that ignore its properly phenomenological features.

How does the temporal knowledge argument fair when exposed to Chalmers' 2-dimensional analysis of the knowledge argument?

ABSTRACT. Thought experiments about de se attitudes and Jackson’s original Knowledge Argument are compared with each other and discussed from the perspective of a computational theory of mind. It is argued that internal knowledge, i.e. knowledge formed on the basis of signals that encode aspects of their own processing rather than being intentionally directed towards external objects, suffices for explaining the seminal puzzles without resorting to acquaintance or phenomenal character as primitive notions. Since computationalism is ontologically (...) neutral, the account also explains why neither Lewis’s two gods nor Mary’s surprise in the Knowledge Argument violate physicalism. (shrink)

Phenomenology is the study of appearance as such. It is a branch of both Ontology and Epistemology, since appearing is being known. By an ‘appearance’ is meant any existent which impinges on consciousness, anything cognized, irrespective of any judgment as to whether it be ‘real’ or ‘illusory.’ The evaluation of a particular appearance as a reality or an illusion is a complex process, involving inductive and deductive logical principles and activities. Opinion has to earn the status of strict knowledge. (...) Knowledge develops from appearances, which may be: (a) objects of perception, i.e. concrete phenomena in the physical or mental domains; (b) objects of intuition, i.e. one’s subjective self, cognitions, volitions and valuations (non-phenomenal concretes); and/or (c) objects of conception, i.e. simple or complex abstracts of preceding appearances. Abstraction relies on apprehensions of sameness and difference between appearances (including received or projected appearances, and projected negations of appearances). Coherence in knowledge (perceptual, intuitive and conceptual) is maintained by apprehensions of compatibility or incompatibility. Words facilitate our construction of conceptual knowledge, thanks to their intentionality. The abstract concepts most words intend are common characters or behaviors of particulars (concrete material, mental or subjective experiences). Granting everything in the world is reducible to waves, ‘universals’ would be equalities or proportionalities in the measures of the features, motions and interrelations of particular waves. Such a theory of universals would elucidate sensation and memory. In attempting to retrace the development of conceptual knowledge from experience, we may refer to certain major organizing principles. It is also important to keep track of the order of things in such development, interrelating specific concepts and specific experiences. By proposing a precise sequence of events, we avoid certain logical fallacies and are challenged to try and answer certain crucial questions in more detail. Many more topics are discussed in the present collection of essays, including selfhood, adduction and other logical issues, the status of mathematical concepts and theology. (shrink)

Many philosophers reduce ordinary knowledge to sensory or, more generally, to perceptual knowledge, which refers to entities belonging to the phenomenic world. However, ordinary knowledge is not only the result of sensory-perceptual processes, but also of non-perceptual contents that are present in any mind. From an epistemological point of view, ordinary knowledge is a form of knowledge that not only allows epistemic access to the world, but also enables the formulation of models of it with (...) different degrees of reliability. Usually epistemologists focus their attention on scientific knowledge, believing that ordinary knowledge does not, or cannot, have an epistemology for it is not in any way rigorous. The papers collected in this volume analyse different aspects of ordinary knowledge and of its epistemology. (shrink)

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, (...) acquaintance is, in itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)
