While introspective methods went out of favour with the decline of Titchener’s analytic school, many important questions concern the rehabilitation of introspection in contemporary psychology. Hatfield rightly points out that introspective methods should not be confused with analytic ones, and goes on to describe their “ineliminable role” in perceptual psychology. Here I argue that certain methodological conventions within psychophysics reflect a continued uncertainty over appropriate use of subjects’ perceptual observations and the reliability of their introspective judgements. My first claim is (...) that different psychophysical methods do not rely equally on the introspective capabilities of experimental subjects. I contrast “minimally-introspective” tasks with “introspection-heavy” ones. It is only in the latter, I argue, that introspection can be said to have a non-trivial role in the subjects’ performance. My second claim is that my rough-and-ready distinction maps onto a number of important “dichotomies” in vision science. Not coincidentally, the introspection-heavy categorisation captures many of the tasks typically considered less able to yield useful information regarding the processes underlying visual sensation.

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to doubt their (...) authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

Viewed from a certain perspective, nothing can seem more secure than introspection. Consider an ordinary conscious episode—say, your current visual experience of the colour of this page. You can judge, when reflecting on this experience, that you have a visual experience as of something white with black marks before you. Does it seem reasonable to doubt this introspective judgement? Surely not—such doubt would seem utterly fanciful. The trustworthiness of introspection is not only assumed by commonsense, it is also taken for (...) granted by many of theorists about the mind. Within both philosophy and the science of consciousness it is widely held that introspection is generally reliable, at least with respect to the question of one’s current (or immediately prior) conscious states. Without this assumption, we could not make sense of theorists’ widespread use of introspection, both in support of their own position and to undermine that of their opponents. (shrink)

How are we to understand the phenomenology of imagining? Attempts to answer this question often invoke descriptors concerning the “vivacity” or “vividness” of our imaginative states. Not only are particular imaginings often phenomenologically compared and contrasted with other imaginings on grounds of how vivid they are, but such imaginings are also often compared and contrasted with perceptions and memories on similar grounds. Yet however natural it may be to use “vividness” and cognate terms in discussions of imagination, it does not (...) take much reflection to see that these terms are ill understood. In this paper, I review both some relevant empirical literature as well as the philosophical literature attempt to get a handle on what it could mean, in an imaginative context, to talk of vividness. As I suggest, this notion ultimately proves to be so problematic as to be philosophically untenable. (shrink)

There is surprising evidence that introspection of our phenomenal states varies greatly between individuals and within the same individual over time. This puts pressure on the notion that introspection gives reliable access to our own phenomenology: introspective unreliability would explain the variability, while assuming that the underlying phenomenology is stable. I appeal to a body of neurocomputational, Bayesian theory and neuroimaging findings to provide an alternative explanation of the evidence: though some limited testing conditions can cause introspection to be unreliable, (...) mostly it is our phenomenology itself that is variable. With this account of phenomenal variability, the occurrence of the surprising evidence can be explained while generally retaining introspective reliability. (shrink)

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

Experiences and beliefs are different sorts of mental states, and are often taken to belong to very different domains. Experiences are paradigmatically phenomenal, characterized by what it is like to have them. Beliefs are paradigmatically intentional, characterized by their propositional content. But there are a number of crucial points where these domains intersect. One central locus of intersection arises from the existence of phenomenal beliefs: beliefs that are about experiences.

Abstract: In chapter 15 of A Materialist Theory of the Mind, D.M.Armstrong offers an account of what he calls “the biological value of introspection”, namely, that “without information…about the current state of our minds, purposive trains mental activity would be impossible.” This paper examines and assesses Armstrong’s “Just-so story about introspective consciousness”—as W.G.Lycan later called it. One moral will be that appreciating this aspect of Armstrong’s view blurs the difference between his own perceptual model of introspection, and the anti-perceptual models (...) advanced by such critics as Sydney Shoemaker .

This chapter (from Routledge's forthcoming handbook on the philosophy of pain) considers the question of whether people are always correct when they judge themselves to be in pain, or not in pain. While I don't show sympathy for traditional routes to the conclusion that people are "incorrigible" in their pain judgments, I explore--and perhaps even advocate--a different route to such incorrigibility. On this low road to incorrigibility, a sensory state's being judged unpleasant is what makes it a pain (or not).

Breaking new ground in the debate about the relation of mind and body, David Armstrong's classic text - first published in 1968 - remains the most compelling and comprehensive statement of the view that the mind is material or physical. In the preface to this new edition, the author reflects on the book's impact and considers it in the light of subsequent developments. He also provides a bibliography of all the key writings to have appeared in the materialist debate.

Kant famously declares that “although all our cognition commences with experience, … it does not on that account all arise from experience”. This marks Kant’s disagreement with empiricism, and his contention that human knowledge and experience require both sensation and the use of certain a priori concepts, the Categories. However, this is only the surface of Kant’s much deeper, though neglected view about the nature of reason and judgment. Kant holds that even our a priori concepts are acquired, not from (...) sensation, but “originally,” because our mind has a fundamental capacity to judge that, upon sensory stimulation, generates the Categories through its basic logical functions of judgment. This “epigenesis” of reason and our fundamental capacity to judge that drives it is the topic of Longuenesse’s fascinating book, and the source of her title. (shrink)

Since its appearance over a decade ago, Timothy Williamson's anti-luminosity argument has come under sustained attack. Defenders of the luminous overwhelmingly object to the argument's use of a certain margin-for-error premise. Williamson himself claims that the premise follows easily from a safety condition on knowledge together with his description of the thought experiment. But luminists argue that this is not so: the margin-for-error premise either requires an implausible interpretation of the safety requirement on knowledge, or it requires other equally implausible (...) assumptions. In this paper I bolster the margin-for-error premise against these attacks by recasting Williamson's own two-part defence, the first part intended to work on the assumption that there is no constitutive connection between the phenomenal and the doxastic, and the second intended to work without this assumption. Pace various luminists, I argue that the appeals to safety needed for Williamson's two-part defence are plausible. I also argue that all that is needed to generate the margin-for-error premise from these safety conditions is an empirical assumption about the kinds of creatures we are: that is, creatures whose beliefs are structured by certain dispositions. By recasting the anti-luminosity argument in this way, we can understand what is really at stake in the debate about luminosity: that is, whether we are luminous. (shrink)

Can perceptual experiences be states of uncertainty? We might expect them to be, if the perceptual processes from which they're generated, as well as the behaviors they help produce, take account of probabilistic information. Yet it has long been presumed that perceptual experiences purport to tell us about our environment, without hedging or qualifying. Against this long-standing view, I argue that perceptual experiences may well occasionally be states of uncertainty, but that they are never probabilistically structured. I criticize a powerful (...) line of reasoning that we should expect perceptual experience to be probabilistic, given their interfaces with unconscious probabilistic information, with behavior responsive to it, and with credences.

We are prone to gross error, even in favorable circumstances of extended reflection, about our own ongoing conscious experience, our current phenomenology. Even in this apparently privileged domain, our self-knowledge is faulty and untrustworthy. We are not simply fallible at the margins but broadly inept. Examples highlighted in this essay include: emotional experience (for example, is it entirely bodily; does joy have a common, distinctive phenomenological core?), peripheral vision (how broad and stable is the region of visual clarity?), and the (...) phenomenology of thought (does it have a distinctive phenomenology, beyond just imagery and feelings?). Cartesian skeptical scenarios undermine knowledge of ongoing conscious experience as well as knowledge of the outside world. Infallible judgments about ongoing mental states are simply banal cases of self-fulfillment. Philosophical foundationalism supposing that we infer an external world from secure knowledge of our own consciousness is almost exactly backward. (shrink)

Several contemporary philosophical theories of introspection have been offered, yet each faces a number of difficulties in providing an explanation of the exact nature of introspection. I contrast the inner-sense view that argues for a causal awareness with the acquaintance view that argues for a non-causal or direct awareness. After critically examining the inner-sense and the acquaintance views, I claim that these two views are complementary and not mutually exclusive, and that both perspectives, conceived of as modes of introspective access, (...) actually broaden the notion of introspection. I then propose a useful distinction between stimuli-induced introspection—i.e., a receptive process whereby some specific mental states induce introspection—and self-triggered introspection—i.e., a selective process whereby the individual’s own interest and volition initiates introspection. I argue that that distinction may eliminate the false dichotomy which claims that only one of those types of awareness, either the causal one or the direct one, is conducive to introspection or is defined as introspection.

What kind of content must visual states have if they are to offer direct (noninferential) justification for our external world beliefs? How must they present that content if the degree of justification they provide is to reflect the nuance of our changing visual experiences? This paper offers an argument for the view that visual states comprise not only a content, but a confidence relation to that content. This confidence relation lets us explain how visual states can offer noninferential perceptual justification (...) of differing degrees for external world beliefs. These confidence relations let visual states justify beliefs in a way that is sensitive to subtle differences in the character of our visual experiences, while still allowing that visual states give us direct access to the external world in virtue of their content.

In “Perceptual Confidence,” I argue that our perceptual experiences assign degrees of confidence. In “Precision, not Confidence, Describes the Uncertainty of Perceptual Experience,” Rachel Denison disagrees. In this reply I first clarify what i mean by ‘perceptual experiences’, ‘assign’ and ‘confidence’. I then argue, contra Denison, that perception involves automatic categorization, and that there is an intrinsic difference between a blurry perception of a sharp image and a sharp perception of a blurry image. -/- .

Perceptual Confidence is the view that perceptual experiences assign degrees of confidence. After introducing, clarifying, and motivating Perceptual Confidence, I catalogue some of its more interesting consequences, such as the way it blurs the distinction between veridical and illusory experiences, a distinction that is sometimes said to carry a lot of metaphysical weight. I also explain how Perceptual Confidence fills a hole in our best scientific theories of perception and why it implies that experiences don't have objective accuracy conditions.

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental strength has been (...) largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

It has often been thought that our knowledge of ourselves is _different_ from, perhaps in some sense _better_ than, our knowledge of things other than ourselves. Indeed, there is a thriving research area in epistemology dedicated to seeking an account of self-knowledge that would articulate and explain its difference from, and superiority over, other knowledge. Such an account would thus illuminate the descriptive and normative difference between self-knowledge and other knowledge.¹ At the same time, self- knowledge has also encountered its (...) share of skeptics – philosophers who refuse to accord it any descriptive, let alone normative, distinction. In this paper, we argue that there is at least one _species_ of self-knowledge that is different from, and better than, other knowledge. It is a specific kind of knowledge of one’s concurrent phenomenal experiences. Call knowledge of one’s own phenomenal experiences _phenomenal knowledge_. Our claim is that some (though not all) phenomenal knowledge is different from, and better than, non-phenomenal knowledge. In other. (shrink)

One striking feature of the contemporary modelling practice is its interdisciplinary nature. The same equation forms, and mathematical and computational methods, are used across different disciplines, as well as within the same discipline. Are there, then, differences between intra- and interdisciplinary transfer, and can the comparison between the two provide more insight on the challenges of interdisciplinary theoretical work? We will study the development and various uses of the Ising model within physics, contrasting them to its applications to socio-economic systems. (...) While the renormalization group methods justify the transfer of the Ising model within physics – by ascribing them to the same universality class – its application to socio-economic phenomena has no such theoretical grounding. As a result, the insights gained by modelling socio-economic phenomena by the Ising model may remain limited. (shrink)

A different way of thinking about how the sciences are organized is suggested by the use of cross-disciplinary computational methods as the organizing unit of science, here called computational templates. The structure of computational models is articulated using the concepts of construction assumptions and correction sets. The existence of these features indicates that certain conventionalist views are incorrect, in particular it suggests that computational models come with an interpretation that cannot be removed as well as a prior justification. A form (...) of selective realism is described which denies that one can simply read the ontological commitments from the theory itself. (shrink)

My goal is to formulate a theory of introspection that can be integrated with a strongly reductionist account of sensations that I have defended elsewhere. In pursuit of this goal, I offer a skeletal explanation of the metaphysical nature of introspection and I attempt to resolve several of the main questions about the epistemological status of introspective beliefs.

Nick Shea’s Representation in Cognitive Science commits him to representations in perceptual processing that are about probabilities. This commentary concerns how to adjudicate between this view and an alternative that locates the probabilities rather in the representational states’ associated “attitudes”. As background and motivation, evidence for probabilistic representations in perceptual processing is adduced, and it is shown how, on either conception, one can address a specific challenge Ned Block has raised to this evidence.

In the second half of the twentieth-century, the traditional problem of other minds was re-focused on special problems with propositional attitudes and how we attribute them to others. How do ordinary people, with no education in scientific psychology, understand and ascribe such complex, unobservable states? In different terminology, how do they go about "interpreting" their peers?

Phenomenal beliefs are beliefs about the phenomenal properties of one's concurrent conscious states. It is an article of common sense that such beliefs tend to be justified. Philosophers have been less convinced. It is sometimes claimed that phenomenal beliefs are not on the whole justified, on the grounds that they are typically based on introspection and introspection is often unreliable. Here we argue that such reasoning must guard against a potential conflation between two distinct introspective phenomena, which we call fact-introspection (...) and thing -introspection; arguments for the unreliability of introspection typically target only the former, leaving the reliability of the latter untouched. In addition, we propose a theoretical framework for understanding thing -introspection that may have a surprising consequence: thing -introspection is not only reliable, but outright infallible. This points at a potential line of defense of phenomenal-belief justification, which here we only sketch very roughly. (shrink)

This paper defends a novel account of how we introspect phenomenal states, the Demonstrative Attention account (DA). First, I present a set of necessary and sufficient conditions for phenomenal state introspection which are not psychological, but purely metaphysical and semantic. Next, to explain how these conditions can be satisfied, I describe how demonstrative reference to a phenomenal content can be achieved through attention alone. This sort of introspective demonstration differs from perceptual demonstration in being non-causal. DA nicely explains key intuitions (...) about phenomenal self-knowledge, makes possible an appealing diagnosis of blindsight cases, and yields a highly plausible view as to the extent of our first-person epistemic privilege. Because these virtues stem from construing phenomenal properties as non-relational features of states, my defense of DA constitutes a challenge to relational construals of phenomenal properties, including functionalism and representationalism. And I provide reason to doubt that they can meet this challenge. (shrink)

The notion of subjective vividness plays a fundamental role in comparing different conscious experiences, yet it is poorly understood and lacks proper definition. Philosophical reflection on this topic is especially scarce. This article proposes a novel account of vividness arguing that its standard operationalisation in psychology conflates two major modality‐general dimensions along which experiences vary—subjective intensity and subjective specificity—which themselves are determined by further modality‐specific factors. The article identifies the neural underpinnings of these factors in the visual domain, demonstrates the (...) unificatory power of the account, and argues that vividness is part of the content of perception.

Block [Block, N. . Two neural correlates of consciousness. Trends in Cognitive Science, 9, 46–52] and Snodgrass claim that a signal detection theory analysis of qualitative difference paradigms, in particular the exclusion failure paradigm, reveals cases of phenomenal consciousness without access consciousness. This claim is unwarranted on several grounds. First, partial cognitive access rather than a total lack of cognitive access can account for exclusion failure results. Second, Snodgrass’s Objective Threshold/Strategic model of perception relies on a problematic ‘enable’ approach to (...) perception that denies the possibility of intentional control of unconscious perception and any effect of following different task instructions on the presence/absence of phenomenal consciousness. Many of Block’s purported examples of phenomenal consciousness without cognitive access also rely on this problematic approach. Third, qualitative difference paradigms may index only a subset of access consciousness. Thus, qualitative difference paradigms like exclusion failure cannot be used to isolate phenomenal consciousness, any attempt to do so still faces serious methodological problems. (shrink)

Most of us are familiar with the phenomenology of mental effort accompanying cognitively demanding tasks, like focusing on the next chess move or performing lengthy mental arithmetic. In this paper, I argue that phenomenology of mental effort poses a novel counterexample to tracking intentionalism, the view that phenomenal consciousness is a matter of tracking features of one’s environment in a certain way. I argue that an increase in the phenomenology of mental effort does not accompany a change in any of (...) the following candidate representational contents: representation of externally presented features, e.g. brightness, contrast, and so on representation of task difficulty, representation of the possibility of error, representation of trying to achieve some state of affairs, representation of bodily changes like muscle tension, or representation of change in cognitive resource availability and lost opportunity cost. While tracking intentionalism about some phenomenal experiences like pains might obtain, it does not seem to obtain for all phenomenal experiences. This puts the intentionalist into an uncomfortable position of trying to explain why some phenomenal experiences have representational content and not others. Since many believe that tracking intentionalism or something like it provides the best chance of naturalizing consciousness, these arguments deserve detailed consideration. (shrink)

The introspective devices framework proposed by Kammerer and Frankish (this issue) offers an attractive conceptual tool for evaluating and developing accounts of introspection. However, the framework assumes that different views about the nature of introspection can be easily evaluated against a set of common criteria. In this paper, I set out to test this assumption by analysing two formal models of introspection using the introspective device framework. The question I aim to answer is not only whether models developed outside of (...) philosophy can be successfully evaluated against the set of conceptual criteria proposed by Kammerer and Frankish, but also whether this kind of evaluation can reveal some limitations inherent to the framework.

What is consciousness? How does the subjective character of consciousness fit into an objective world? How can there be a science of consciousness? In this sequel to his groundbreaking and controversial The Conscious Mind, David Chalmers develops a unified framework that addresses these questions and many others. Starting with a statement of the "hard problem" of consciousness, Chalmers builds a positive framework for the science of consciousness and a nonreductive vision of the metaphysics of consciousness. He replies to many critics (...) of The Conscious Mind, and then develops a positive theory in new directions. The book includes original accounts of how we think and know about consciousness, of the unity of consciousness, and of how consciousness relates to the external world. Along the way, Chalmers develops many provocative ideas: the " consciousness meter", the Garden of Eden as a model of perceptual experience, and The Matrix as a guide to the deepest philosophical problems about consciousness and the external world. This book will be required reading for anyone interested in the problems of mind, brain, consciousness, and reality. (shrink)
