A common sense view is illustrated by Doubting Thomas, and surfaces in many philosophical and psychological writings : Touching is better than seeing. But can we make sense of this privilege? We rule out that it could mean that touch is more informative than vision, more ‘objective’ or more directly in contact with reality. Instead, we propose that touch offers not a perceptual, but a metacognitive advantage: touch is not more objective than vision but rather provides comparatively higher subjective (...) certainty.

In Philosophy and the Mirror of Nature, Richard Rorty presents powerful arguments against traditional epistemology, conceived as a quest both for empirical grounds that provide certainty and for necessary truths that provide a conceptual framework within which to couch empirical findings. Rorty finds traditional epistemology in general, and specifically any appeal to representation that might ground knowledge, to be an unmitigated failure. In this paper, I show that Rorty at least considered but ultimately rejected the possibility of a type (...) of epistemically relevant, foundational representation with a normative status. Drawing on the work of Tyler Burge, I argue that Rorty was too quick in dismissing the important, epistemically foundational role of perceptual representation. A new and improved picture of foundational epistemology emerges. Throughout the paper, I aim to shed light on the fundamental disconnect between Rorty’s and Burge’s approaches to epistemology, and to philosophical investigation more generally. (shrink)

The article proposes a comparison between the critique that Antoine Arnault (1612-1694) raises against Malebranche’s views on perception and the critique that Thomas Reid (1710-1796) moves against the theory of ideas defended by Berkeley and Hume. Both Arnault and Reid advocate a position according to which our perceptions allow us to have direct knowledge of material objects existing independently of us and not only of representations of them. Arnault proposes different arguments to refute Malebranche. In doing that he doesn’t completely (...) reject the Cartesian representational account of perception. Reid is more radical: in order to refuse Berkeley and Hume he rejects the whole theory of ideas, and focuses instead on the mental powers through which we cognize reality. (shrink)

This book asks whether there any limits to the sorts of religious considerations that can be raised in public debates, and if there are, by whom they are to be identified. Its starting point is the work of Richard Rorty, whose pragmatic pluralism leads him to argue for a politically motivated anticlericalism rather than an epistemologically driven atheism. Rather than defend Rorty’s position directly, Gascoigne argues for an epistemological stance he calls ‘Pragmatist Fideism’. The starting point for this exercise in (...) what Rorty calls ‘Cultural Politics’ is an acknowledgement that one must appeal to both secularists and those with religious commitments. In recent years ‘reformed’ epistemologists have aimed to establish a parity of epistemic esteem between religious and perceptual beliefs by exploiting an analogy in respect of their mutual vulnerability to sceptical challenges. Through an examination of this analogy, and in light of Wittgenstein’s On Certainty, this book argues that understood correctly the ‘parity’ argument in fact lends epistemological support to the argument that religious considerations should not be raised in public debate. The political price paid—paying the price of politics—is worth it: the religious thinker is provided with a good reason for maintaining that their practices and beliefs are not undermined by other forms of religious life.

We provide a new account of the oft-mentioned special character of touch, showing that its superior reliability is subjective rather than objective : Touch provides higher certainty than vision, for the same level of objective accuracy.

Contemporary epistemology has been moving away from classical foundationalism—the thesis that our empirical knowledge is grounded in perceptual beliefs we know with certainty. McGrew reexamines classical foundationalism and offers a compelling reconstruction and defense of empirical knowledge grounded in perceptual certainty. He articulates and defends a new version of foundationalism and demonstrates how it meets all the standard criticisms. The book offers substantial rebuttals of the arguments of Kuhn and Rorty and demonstrates the value of the (...) classical analytic approach to philosophy. 'Foundations' will interest philosophers of science, language, and the mind. (shrink)

This paper aims to stablishes the sense in which propositions included under the perceptual use of ‘seeing-as’, developed by Wittgenstein in the Second Part of Philosophical Investigations, are justifiable from an epistemic point of view. To do this, first, it will be clarified the internal link between ‘visual experience’ and ‘interpretation’ for the type of mentioned cases. Second, it will be shown how the ‘seeing-as’ respects the rule-following paradox’s solution, as long as it does not presuppose any intermediary or (...) need anyone to account for what is perceived, highlighting the notions of ‘practice’, ‘familiarity’ and ‘context’ common both in the aforementioned solution and in the ‘seeing-as’ cases. Third, the general distinction between certainties or ‘hinges’ and ‘epistemic propositions’ presented by Wittgenstein in On Certainty will be applied to cases of aspect perception as a possible field of application of the so called Hinge Epistemology, showing how, in specific cases, the perceptual certainties that shape our way of life and that are groundless, can be recontextualized and merit reasonable justification.Keywords: Wittgenstein, aspect perception, seeing-as, hinges, certainty, justification.

Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, (...) of our belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.

When we are fatigued, we feel that our performance is worse than when we are fresh. Yet, for over 100 years, researchers have been unable to identify an objective, behavioral measure that covaries with the subjective experience of fatigue. Previous work suggests that the metrics of signal detection theory —response bias and perceptual certainty —may change as a function of fatigue, but no work has yet been done to examine whether these metrics covary with fatigue. Here, we investigated (...) cognitive fatigue using SDT. We induced fatigue through repetitive performance of the n-back working memory task, while functional magnetic resonance imaging data was acquired. We also assessed cognitive fatigue at intervals throughout. This enabled us to assess not only whether criterion and d’ covary with cognitive fatigue but also whether similar patterns of brain activation underlie cognitive fatigue and SDT measures. Our results show that both criterion and d’ were correlated with changes in cognitive fatigue: as fatigue increased, subjects became more conservative in their response bias and their perceptual certainty declined. Furthermore, activation in the striatum of the basal ganglia was also related to cognitive fatigue, criterion, and d’. These results suggest that SDT measures represent an objective measure of cognitive fatigue. Additionally, the overlap and difference in the fMRI results between cognitive fatigue and SDT measures indicate that these measures are related while also separate. In sum, we show the relevance of SDT measures in the understanding of fatigue, thus providing researchers with a new set of tools with which to better understand the nature and consequences of cognitive fatigue.

The Problem of the Speckled Hen is a potential stumbling-block for any philosophical treatment of perceptual certainty. Roderick Chisholm argues in the third edition of his Theory of Knowledge (Prentice Hall, 1989) that the Speckled Hen is not a problem for the account of the perceptually certain contained in that book. In this note, I argue that Chisholm’s defense of his account does not work.

This chapter contains section titled: The Skeptic's Undoing Cartesian Certainty.

Our senses provide us with information about the world, but what exactly do they tell us? I argue that in order to optimally respond to sensory stimulations, an agent’s doxastic space may have an extra, “imaginary” dimension of possibility; perceptual experiences confer certainty on propositions in this dimension. To some extent, the resulting picture vindicates the old-fashioned empiricist idea that all empirical knowledge is based on a solid foundation of sense-datum propositions, but it avoids most of the problems (...) traditionally associated with that idea. The proposal might also explain why experiences appear to have a non-physical phenomenal character, even if the world is entirely physical. (shrink)

In informal terms, abductive reasoning involves inferring the best or most plausible explanation from a given set of facts or data. It is a common occurrence in everyday life and crops up in such diverse places as medical diagnosis, scientific theory formation, accident investigation, language understanding, and jury deliberation. In recent years, it has become a popular and fruitful topic in artificial intelligence research. This volume breaks new ground in the scientific, philosophical, and technological study of abduction. It presents new (...) ideas about inferential and information-processing foundations for knowledge and certainty. The authors argue that knowledge arises from experience by processes of abductive inference, in contrast to the view that it arises non-inferentially, or that deduction and inductive generalization are enough to account for knowledge. Much AI research is hypothetical, so the importance of this book is that it reports key discoveries about abduction that have been made as a result of designing, building, testing, and analyzing actual working knowledge-based systems for medical diagnosis and other abductive tasks. The book tells the story of six generations of increasingly sophisticated generic abduction machines, RED-1, RED-2, PEIRCE, MDX2, TIPS, QUAWDS, and the discovery of reasoning strategies that make it computationally feasible to form well-justified composite explanatory hypotheses, despite the threat of combinatorial explosion. The final chapter argues that perception is logically abductive and presents a layered-abduction computational model of perceptual information processing. This book will be of great interest to researchers in AI, cognitive science, and philosophy of science. (shrink)

Wordly internalists claim that while internal duplicates always share the same evidence, our evidence includes non-trivial propositions about our environment. It follows that some evidence is false. Worldly internalism is thought to provide a more satisfying answer to scepticism than classical internalist views that deny that these propositions about our environment might belong to our evidence and to provide a generally more attractive account of rationality and reasons for belief. We argue that worldly internalism faces serious difficulties and that its (...) apparent advantages are illusory. First, it cannot adequately handle some not terribly strange cases of perceptual error. Second, it cannot explain why one should plan to use their evidence to update their beliefs. The second issue allows us to explain why cases of misplaced certainty do not require us to introduce false evidence into our views and that why the alleged advantage of worldly internalism in resisting sceptical pressures is illusory.

Clear and distinct perception is the centrepiece of Descartes’s philosophy — it is the source of all certainty — but what does he mean by ‘clear’ and ‘distinct’? According to the prevailing approach, what it means for a perception to be clear is that its content has a certain objective property, like truth. I argue instead that clarity is at least partly a subjective, phenomenal quality whereby a content is presented as true to the perceiving subject. Clarity comes in (...) degrees. Any weak degree of clarity, available to the senses, can be merely subjective, since what it presents as true may not actually be true. But complete clarity, available to intellectual perception, has an objective dimension, since what it presents as true is always some truth, some bit of reality. Further, I argue that the other perceptual qualities that Descartes identifies — obscurity, confusion, and distinctness — are all defined in terms of clarity. Of particular note is the fact that distinctness is not a positive feature to be added to clarity: a distinct perception is just a completely clear perception. (shrink)

Summary The paper presents the result of a collective reflection inspired by the individual suggestions of 30 researchers working in different research areas. They are all familiar with the Experimental Phenomenology of Perception, and are aware of the importance that this approach might represent nowadays in their specific research field. The picture that emerges from this ‘mosaic’ stimulates us to consider the potential future developments of this approach if we accept that we need to push its borders beyond the traditional (...) aims of the study of perception (as masterfully developed by the historic Italian Maestri of this approach). If we take this broader view, the Experimental Phenomenology of Perception can extend its perimeters from an analysis of strictly perceptual aspects to an analysis of cognitive and metacognitive aspects (such as aesthetic evaluations, the perception of risk, the experience of certainty/uncertainty in a reasoning process, the perception of proximity to/distance from the solution to a problem and meaning-making in language). The cognitive and metacognitive aspects referred to are grounded in and modelled on the perceiver’s experience of a given situation. (shrink)

Here, we explore the sensitivity of different awareness scales in revealing conscious reports on visual emotion perception. Participants were exposed to a backward masking task involving fearful faces and asked to rate their conscious awareness in perceiving emotion in facial expression using three different subjective measures: confidence ratings , with the conventional taxonomy of certainty, the perceptual awareness scale , through which participants categorize “raw” visual experience, and post-decision wagering , which involves economic categorization. Our results show that (...) the CR measure was the most exhaustive and the most graded. In contrast, the PAS and PDW measures suggested instead that consciousness of emotional stimuli is dichotomous. Possible explanations of the inconsistency were discussed. Finally, our results also indicate that PDW biases awareness ratings by enhancing first-order accuracy of emotion perception. This effect was possibly a result of higher motivation induced by monetary incentives. (shrink)

This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

Along the way, a comparison with Wittgenstein's own views in on Certainty and with the positions held by other prominent hinge (...) epistemologists, particularly Moyal-Sharrock, Pritchard and Wright, is provided.

ABSTRACTDuncan Pritchard proposes a biscopic solution to the problem of radical skepticism, which consists in epistemological disjunctivism and a theory about the limits of rational evaluation inspired by Wittgenstein's On Certainty. According to the latter theory, we cannot have rationally grounded knowledge of the denials of radical skeptical hypotheses, a consequence that Pritchard finds attractive insofar as he thinks that claims to know the falsity of radical skeptical hypotheses are epistemically immodest. I argue that there is room for a (...) neo-Moorean to dispute Pritchard's argument for the Wittgensteinian proposal and I raise some doubts about its underlying motivation. Finally, I put forward an alternative, which I call “moderate neo-Moorean epistemological disjunctivism.” While this theory contends that we possess rationally grounded anti-skeptical knowledge, it also allows for a degree of epistemic modesty, by conceding that perceptual knowledge never amounts to knowledge that is absolutely certain.

Western scholars have speculated for centuries about the perceptual capacities of non-western peoples, of children, and of animals; and, more recently, about the representation and communication of perceptual experience in language. Colour is a particularly intriguing domain within which to study the communication of experience because the physical stimulation necessary for the perception of colour, light radiation, can be specified with precision, and creates an aura of rigour and certainty.

Central elements of W. V. Quine’s epistemology are widely and deeply misunderstood, including the following. He held from first to last that our evidence consists of the stimulations of our sense organs, and of our observations, and of our sensory experiences; meeting the interpretive challenge this poses is a sine qua non of understanding his epistemology. He counted both “This is blue” and “This looks blue” as observation sentences. He took introspective reports to have a high degree of certainty. (...) He endorsed outright Hume’s “skeptical” argument concerning induction. His naturalized epistemology is simply naturalistic, or scientific, epistemology stripped of the project of rational reconstruction, and is thoroughly normative. Quine was unconditionally a scientific philosopher who took our theories to be answerable ultimately to our perceptual experiences (sensations)—and conditionally an empiricist, empiricism being a scientific theory that has no competitors worthy of the name. I attempt to make all of this clear, and conclude by offering a concise formulation of his epistemology. (shrink)

Epistemological probability is the kind of probability relative to a body of evidence. Many philosophers, including Henry Kyburg and Roderick Chisholm, hold that all epistemological probabilities reflect a relation between an evidential body of propositions and other propositions. But this article argues that some epistemological probabilities for empirical propositions must be relative to non-propositional evidence, specifically the contents of non-propositional perceptual states. In doing so, the article distinguishes between internalism and externalism regarding epistemological probability, and argues for a version (...) of awareness internalism. The article draws three main concluding lessons. First, epistemological probability is not to be identified with the sort of objective, experience-independent probability that is familiar from statistical and propensity interpretations of probability. Second, it is doubtful that epistemological probability is measurable, in any useful way, by real numbers, even if it admits of comparative assessments. Third, contrary to the familiar claim of C. I. Lewis, epistemological probability should not be viewed as requiring a basis of certainty. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Background Theory of Delusion and Existential PhenomenologyRichard G. T. Gipps (bio) and John Rhodes (bio)KeywordsPhenomenology, psychological explanation, epistemology, schizophreniaSituating and Clarifying the PaperThe commentaries of Nassir Ghaemi and Giovanni Stanghellini help to sketch out the intellectual landscape of philosophical perspectives in psychiatry, and situate our paper within it. A happy convergence between the analytical philosophy perspective from which we were writing, and the existential–phenomenological paradigm described by both (...) authors, is the result. Stanghellini in particular carefully describes three main theories of existential deformations, tracing delusion formation back to either (i) a disturbance of meaning synthesis conceived as a dysfunction of a Husserlian consciousness, (ii) a disturbance of pre-reflective self-consciousness resulting in a kind of paralyzing hyperreflexivity, and (iii) (Stanghellini’s preferred model) a disturbance of embodiment. This final account views delusion as springing from a failure in the subject’s corporeal and praxical being-in-the-world. As the subject’s practical, pre-reflective grip on the world is loosened, so their minds become unconstrained by that understanding and practical rationality immanent within that grip, and thought, now unconstrained, starts to travel through delusional worlds. Stanghellini accordingly views our model as an example of a disembodiment theory, which allows it to overcome the disadvantages of the first two models, which may both, in their own ways, overvalue the rôle of (disturbances of) reflective consciousness in the formation (and delusional deformation) of everyday understanding.Being situated within a preexisting landscape has both its benefits and its disbenefits, the principle example of the latter being the potential assimilation of anything new to what has already been said. Thus, although we are grateful to our commentators for placing us on the larger historical and conceptual map, it may be helpful to briefly rehearse our motivations for drawing on the philosophical ideas of the Bedrock and Background in our theory of delusion. Our paper was primarily motivated by a concern that current, psychologically mainstream, cognitive models of delusion, although helpfully drawing our attention to common reasoning and perceptual deficits in the person with psychosis, fail to adequately account for what is delusional about delusions. It was, in [End Page 321] particular, to account for the certainty with which the deluded person clings to often quite extraordinary beliefs that we drew on the epistemological notion of the background. And although this epistemological notion fits quite neatly with ontological concerns regarding the embodied and praxical character of human existence, it is the particular epistemic rôle that it played in our theory—to do with the extraratiocinative constraint on judgement provided by the Background—that we wish to stress here.We return to this shortly, but first wish to comment briefly on two specific considerations raised by the commentaries. The first concerns Stanghellini’s claim that, for us, “when studying delusions, the focus should be on providing an adequate framework for understanding, rather than providing empirical hypotheses to be tested” (2008, 311–314). It seems to us, however, that both are equally important. What we wished to stress, however, was that empirical hypothesis testing may be led astray if it is not informed by an adequate framework for understanding. For example, most cognitive psychological experiments on delusions concern themselves with the individual’s ability to make appropriate guesses (e.g., regarding the color of beads in a bag), and their tendency to jump to conclusions; they do not concern themselves with the kinds of extraordinary conviction and certainty met with in delusion. The risk run by empirical researchers of cognitive factors in delusion is that a lack of a prior adequate theorization of delusion makes for accounts that are ultimately only of the formation, not of delusion in particular but rather of false or unusual beliefs more generally. An analytical approach, however, can help to explicate the ways in which the psychiatric concept of delusion fails to be adequately characterized by the quite general ‘external criteria’ of delusion (as Jaspers [1963] called them: falsity, stubbornness, uncommon), and aids in the construction of empirical hypotheses this time constrained by an understanding of the true ‘internal criteria’ of psychotic belief. Such an approach helps to spell out the... (shrink)

Argumentation is a form of communication, rather than an application of(formal) logic, and is used in communicative activity as a means forinquiry, although it is more typically thought of as bringing inquiry toclosure. Thus interpretation is an intrinsic and crucial aspect ofconversational (interactive) argumentation. In order to further thisunderstanding of argumentative activity, I propose a procedure forinterpretation that draws upon hermeneutic phenomenology. In response tocriticisms by argumentation theorists (and others) who understand thistradition as oriented to psychological, perceptual, or textual (...) objects, Iargue that hermeneutic phenomenology supports methods for analysis ofpublic communicative activity. The resulting conception of ’thick argumentation‘ responds to contemporary (postmodern) claims that argumentation valorizes univocity, stasis, and certainty at the expense ofthe pluralism, fluctuation, and range of epistemic results thatcharacterize discourse in the public sphere.

In the present paper I shall argue that the real problem here is the very idea that there is a dilemma that compels us to choose sides. We can hold both that the meditator's doubts are fully serious, and that they leave the perspective of common sense largely unscathed. The key to dissolving the dilemma is to see that the meditator observes a distinction between two levels of epistemic standards: the very demanding standards appropriate to certainty, understood in a (...) rather technical sense of that term; and the commonplace standards appropriate to reasonable belief. The significance of this levels distinction has not been widely appreciated but it has important consequences both for how we are to understand the skepticism about the senses that is at issue and for appreciating the extent to which Descartes acknowledges and retains our natural trust in the senses. I aim to show that the meditator’s skepticIsm about the senses specifically concerns the possibility of sensory certainties, and is quite serious. It is intended to lead one to a stable change of mind about what is most certain. But a skepticIsm about sense-based certainty leaves the matter of whether experience provides a reliable basis for belief untouched by reasonable doubt. Since the meditator's doubts presuppose very demanding standards they have no bearing on our assessments from within the common sense perspective. I defend this view by arguing that the methodological 'withdrawal of assent' from perceptual beliefs is a mere pretense that is compatible with continued endorsement. Despite the seriousness with which the method of doubt is pursued, there is an important sense in which the meditator never doubts the basic deliverances of his senses. This helps explain the practical insulation of perceptual beliefs from skepticism. With one minor qualification, the meditator retains his natural trust in the senses throughout - although Descartes’ rhetoric sometimes suggests otherwise. Note that I shall be exploring the skepticism about the senses as we find it in the First Meditation. This paper does not purport to discuss all of the skeptical doubts of the First Meditation, e.g., skepticism about mathematical truths, God's existence and reason. Instead I shall focus solely upon the ways in which the meditator's doubts bear on his perceptual beliefs. The rationale for this restriction is twofold: 1) in the first place Descartes describes the general aim of the skeptical doubts of the First Meditation m terms of 'freeing us from our preconceived opinions, and providing the easiest route by which the mind may be led away from the senses’. I am specifically concerned to qualify this ambition and argue that Descartes retains throughout his preconceived trust in the reliability of the senses; and 2) the Meditations has long been thought to provide the grounds for a radical form of external world skepticism which not only denies us knowledge of, but also any reason to believe in, the existence of an external world. My discussion of Descartes' perceptual doubts is intended to show just how distant any such skepticism is from Descartes' own thoughts and intentions. (shrink)

Among the means of valid cognition, the one which appears first in every enumeration, which was considered as being the basis of all other means of knowledge and which was considered as a legitimate method of knowledge by all schools of Indian thought is perception (pratyakṣa). With regard to perception, we can naturally expect such questions as ‘what is it to perceive’ or ‘what do we mean when we say that something is perceived’. It is generally believed that the philosophical (...) theories of perceptions are really theories about what we mean by ordinary perceptual statements. In considering our knowledge about the external world, the philosopher tends to consider the way in which perception can and does provide us with the knowledge and the nature, extent and certainty of knowledge it provides us with. It is a well acknowledged fact that perception is the fundamental source of knowledge. In Buddhist epistemology, a systematic discussion on perception is found in the writings of Dignāga’s Pramāṇasamuccaya with vṛitti, who belongs to Yogācāra school of Buddhism of Mahayana tradition. An attempt has been made in this paper to explain and examine critically the first chapter of Pramāṇasamuccaya with vṛitti, i.e., perception with special reference to Non-Buddhist schools, namely Nyāyayikas, Vaiśeṣikas, Sāṁkhyans and Mīmāṁsakas. To explain it, the paper has been divided into three sections. Section I deals with Dignāga’s theory of perception and examination of non-Buddhist school's theory of perception, section II deals with Dignāga’s examination of nature of Perception with reference to non-Buddhists schools and section III deals with conclusion.

The skeptical doubts entertained by Descartes give rise to seven distinct theses characterizable as solipsistic, each focused on one of three general epistemological problems, that of the reality of the perceived, that of the existence of the unperceived, and the so-called problem of the existence of an external world. The skeptical challenge in each case is concerned not with absolute certainty, but with the question of whether there is any warrant whatever for bridging the evidential gap between data and (...) common-sense tenets. ;The challenge is shown to be answerable neither with pragmatic considerations nor with semantic ones, nor by appeal either to usual perceptual procedures, or to the factual presuppositions of enquiry. Coherentist criteria of fit, consilience, and simplicity are equally uncompelling and irrelevant. Detailed examination shows charges of parasitism, whether self-referential, epistemic, conceptual, or linguistic, to fail against all but one form of Cartesian solipsism, that arising from the external world problem. In particular, it appears not only that the three assumptions of any linguistic parasitism argument, to wit, the ontocentricity of language, the impossibility of private language, and the logocentricity of thought, are each false, but also that solipsistic theses may be formulated either in revised English or in imagic thought. ;The conclusion dictated is that skepticism regarding the reality and existence of everyday objects is answerable only by a rational foundationalist enterprise building on the terrain of the sensuous flux of the radical skeptic. An introspective analysis of instances of thinking, whether non-symbolic, imagic, or linguistic, and of feeling and motivation shows an indispensable element of the thinking subject to be the tactual body. The accommodation of this circumstance makes forms of solipsism questioning the reality of the observed Googolizably arbitrary, and consequently their espousal irrational. Finally, an extrapolation of an inverse probability argument shows forms of solipsism denying the existence of the unobserved to be extremely unlikely to be true. The argument utilizes a method of random selection based on free choice, the one remaining option given the proscriptions against empirical knowledge. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Authenticity in Robert Musil’s Man Without QualitiesKelly CobleIHow is a man without qualities even possible? The question, also a translation of the title of a recent essay mining the philosophical sources of Robert Musil's The Man Without Qualities, has been a perennial one. The Austrian novelist's portrayal of an existence without the density of particularity has been an object of interminable conjecture.1 In the search for an interpretive foothold, (...) the bulk of Musil's commentators has identified Ernst Mach's "doctrine of elements," with its implication of the anonymity of perception, as the chief inspiration of Musil's portrait of a dispossessed inner life.2 Against this view Cambridge philosopher G. H. von Wright has asserted that Mach's influence was "incidental and without deeper significance to the content of Musil's later thoughts."3 Von Wright notes that Musil rejected Mach's skeptical and phenomenalist theses in his 1908 dissertation on Mach's theories, defending instead a realist position in the philosophy of physics. Yet another commentator has adduced evidence of Musil's persistent engagement in the sort of act-object analysis of states of consciousness that one would expect from a follower of Franz Brentano.4In the following pages I will show that Musil's literary masterpiece rests on a synthesis of Machian and Brentanist motifs. But the main impetus of Musil's presentation of an interior with substitutable qualities was not one or another claim in the domain of modern epistemology, "realism" versus "idealism," "phenomenology" versus "phenomenalism," but a crisis in moral reflection ensuing from a commitment to the standpoint of value-neutral objectivity. This standpoint gains its [End Page 337] appeal when both of the known pathways to moral certainty—both the conservative-traditional one of allegiance to enduring practices and institutions and the liberal-enlightenment one of deference to the universal requirements of reason—appear as blind alleys, as they did to inhabitants of Central Europe after the turn of the century and especially in the aftermath of the Great War. To exist without qualities is to abandon oneself to the purely theoretical outlook, and so to be unable to construct a narrative rendering the episodes of one's life as parts of a process with cumulativeness and direction. To live "without qualities" is to live the loss of moral narrative. Accordingly, the intent of Musil's literary investigations is both to illuminate the conditions of this loss and to assay the conditions of ethical life regained.IIAccording to Mach's doctrine of elements, the isolable sensations that constitute the ultimate points of psychological analysis are the very elements with which the physical sciences also have to deal, albeit the physical sciences deal with these elements in abstraction from their relations to our sense physiology. The core thesis of the doctrine is thus that the "sensations" isolated in psychological analysis are not mental events, ontologically speaking, but rather points of perfect convergence of the domains of psychology and physics. What psychologists call "sensations," namely "colors, tones, warmths, pressures, spaces, times, and so on," constitute "the actually real elements of the world"—albeit before the world has been banished to a shadowy realm of pure substances beyond the limits of perception.5 The ultimate, irreducible constituents of reality are not unanalyzable substances and subjects but associations and complexes of elements that compose the luminous fabric of experience.Mach's doctrine of elements replaces substance dualism with a brand of monism that analytical philosophers have tagged "ontological phenomenalism." Mach believed that widespread subscription to phenomenalism would have a liberating effect on the sciences, enabling empirical researchers to get on with the business of subjecting relatively permanent, relatively stable complexes of perceptual elements to the mathematical formalism that is the goal of the exact natural sciences.There is a widespread assumption that Mach was a sense-datist—an epistemological "pointillist" who replaced substances with dots of pure sensation that, in their aggregation, compose our perceptions. The [End Page 338] assumption is false. In Mach's view the sensations of which we can possibly be conscious are irreducibly features of wholes: "The single sensation is neither conscious nor unconscious. It... (shrink)

This paper discusses responses to Disagreement, Deference, and Rational Commitment from Bogardus and Burton, Thurow, and Kvanvig. Each of these responses objects to the rationalist account of “partisan justification” defended in the book. After explaining partisan justification and its significance, I first take up Bogardus and Burton’s argument for a more restrictive account of partisan justification which says that partisan justification requires certainty. I argue that this account yields implausible discontinuities in the verdicts given to nearly identical cases. Next, (...) I consider Thurow’s suggestion that perceptual evidence can provide partisan justification without supporting rational insight. I explain why insight plays a crucial role in cases where perceptual beliefs enjoy partisan justification.

In lieu of an abstract, here is a brief excerpt of the content:Authenticity in Robert Musil’s Man Without QualitiesKelly CobleIHow is a man without qualities even possible? The question, also a translation of the title of a recent essay mining the philosophical sources of Robert Musil's The Man Without Qualities, has been a perennial one. The Austrian novelist's portrayal of an existence without the density of particularity has been an object of interminable conjecture.1 In the search for an interpretive foothold, (...) the bulk of Musil's commentators has identified Ernst Mach's "doctrine of elements," with its implication of the anonymity of perception, as the chief inspiration of Musil's portrait of a dispossessed inner life.2 Against this view Cambridge philosopher G. H. von Wright has asserted that Mach's influence was "incidental and without deeper significance to the content of Musil's later thoughts."3 Von Wright notes that Musil rejected Mach's skeptical and phenomenalist theses in his 1908 dissertation on Mach's theories, defending instead a realist position in the philosophy of physics. Yet another commentator has adduced evidence of Musil's persistent engagement in the sort of act-object analysis of states of consciousness that one would expect from a follower of Franz Brentano.4In the following pages I will show that Musil's literary masterpiece rests on a synthesis of Machian and Brentanist motifs. But the main impetus of Musil's presentation of an interior with substitutable qualities was not one or another claim in the domain of modern epistemology, "realism" versus "idealism," "phenomenology" versus "phenomenalism," but a crisis in moral reflection ensuing from a commitment to the standpoint of value-neutral objectivity. This standpoint gains its [End Page 337] appeal when both of the known pathways to moral certainty—both the conservative-traditional one of allegiance to enduring practices and institutions and the liberal-enlightenment one of deference to the universal requirements of reason—appear as blind alleys, as they did to inhabitants of Central Europe after the turn of the century and especially in the aftermath of the Great War. To exist without qualities is to abandon oneself to the purely theoretical outlook, and so to be unable to construct a narrative rendering the episodes of one's life as parts of a process with cumulativeness and direction. To live "without qualities" is to live the loss of moral narrative. Accordingly, the intent of Musil's literary investigations is both to illuminate the conditions of this loss and to assay the conditions of ethical life regained.IIAccording to Mach's doctrine of elements, the isolable sensations that constitute the ultimate points of psychological analysis are the very elements with which the physical sciences also have to deal, albeit the physical sciences deal with these elements in abstraction from their relations to our sense physiology. The core thesis of the doctrine is thus that the "sensations" isolated in psychological analysis are not mental events, ontologically speaking, but rather points of perfect convergence of the domains of psychology and physics. What psychologists call "sensations," namely "colors, tones, warmths, pressures, spaces, times, and so on," constitute "the actually real elements of the world"—albeit before the world has been banished to a shadowy realm of pure substances beyond the limits of perception.5 The ultimate, irreducible constituents of reality are not unanalyzable substances and subjects but associations and complexes of elements that compose the luminous fabric of experience.Mach's doctrine of elements replaces substance dualism with a brand of monism that analytical philosophers have tagged "ontological phenomenalism." Mach believed that widespread subscription to phenomenalism would have a liberating effect on the sciences, enabling empirical researchers to get on with the business of subjecting relatively permanent, relatively stable complexes of perceptual elements to the mathematical formalism that is the goal of the exact natural sciences.There is a widespread assumption that Mach was a sense-datist—an epistemological "pointillist" who replaced substances with dots of pure sensation that, in their aggregation, compose our perceptions. The [End Page 338] assumption is false. In Mach's view the sensations of which we can possibly be conscious are irreducibly features of wholes: "The single sensation is neither conscious nor unconscious. It... (shrink)

Davidson aims to explain how it is that we come by knowledge of the world, our own minds and other minds, and to show that knowledge of other minds is the more fundamental. A community of minds is the basis of all knowledge and provides the measure of all things. Davidson believes that understanding this will provide a reply to the skeptic. I argue that while Davidson's work may provide a reply to a new skeptical problem, it is not clear (...) how it engages with traditional skeptical problems. In order to better understand Davidson's work in connection with the latter, I suggest that we look to the writing of Wittgenstein. I also suggest that when Davidson writes of knowledge, he is not thinking along traditional lines. Finally, I suggest that, while there exist inferential and perceptual models of our knowledge of another mind, Davidson's work offers yet another model. (shrink)

The conception of first‐person knowledge of thought and experience was present in antiquity. It played a major role in Western philosophy in the early modern era as an integral part of the Cartesian and Lockean conceptions of the mind. If inner sense is a form of introspective self‐observation yielding knowledge, as it seemed to be, then awareness of the contents of the mind appears to be analogous to what we take to be awareness or consciousness of objects by the exercise (...) of a perceptual faculty. Descartes thought that the impossibility of doubt implied the presence of complete certainty. Consequently, he cast what he called 'thoughts' in the role of the certain foundations of empirical knowledge. Both Locke and Descartes supposed that one is conscious of what passes in the mind, and that what one is conscious of one knows to exist or obtain. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Human Goodness: Pragmatic Variations on Platonic ThemesCatherine E. MorrisonHuman Goodness: Pragmatic Variations on Platonic Themes by Paul Schollmeier Cambridge: Cambridge University Press, 2006. Pp. x + 302. $80.00, cloth.This is a book about spirits—human, godly, ghostly, and alcoholic. Paul Schollmeier's Human Goodness: Pragmatic Variations on Platonic Themes explores how humble humans act morally in an absurd world. Schollmeier contends that the Socratic spirit, or daimon, of self-knowledge and (...) hypothesis testing provides the foundation for a deeply human moral philosophy. It is, in Schollmeier's elegant phrasing, daimonic rather than eudaimonic, joining Aristotle and Plato with William James, as well as contributions from the ghosts of David Hume and Immanuel Kant and a few rounds of whiskey. Spirits abound! Mixing Socratic skepticism with Jamesian empiricism, Schollmeier argues that we act best when we apply general principles held as opinion (not as certain knowledge), and tested through experience, to our particular situation. When these opinions yield fruit, we find ourselves less at the whim of our capricious surroundings; when they do not, we are obliged to recognize the provisional nature of our opinions and change them. The ends of these day-to-day activities reflect a far grander cosmological order, one we ignore to our mortal (and moral) peril. It is by engaging in this intellectual activity that we are made happy, and it is in measured pursuit of this happiness that we are virtuous. Our actions are neither absolutely true nor perfect. They are instead the best that we can do. And for a reviewer attempting to encapsulate a finely nuanced book in a small space, this is comforting advice indeed. [End Page 190]The book begins with a puzzle: The curious twin claims in Plato's Apology that, true to the Delphic oracle's proclamation, Socrates is both wise and knows nothing. The key to this apparent paradox, Schollmeier contends, is the difference between divine knowledge, "ultimate, nonhypothetical knowledge of final causes" (6), and human knowledge, which is hypothetical only. Schollmeier marshals William James to argue that as humans, we encounter objects of knowledge perceptually; even our concepts are fashioned from this meager material. Without access to divine knowledge, humans must test hypotheses and assume that they are true only provisionally.James's (and Hume's) emphasis on the passions as the foundation for action, however, gives Schollmeier pause. In order to construct a moral philosophy that avoids absolutism but remains objective, Schollmeier argues for a harmony between the intellectual and the passional that is ultimately rational, our Socratic daimon. We are neither gods nor animals. Should we surrender rationality to desire, Schollmeier warns in concert with Socrates, our already fragile perceptual knowledge will be further distorted by fickle emotion. It is precisely because our grasp on the world is so tenuous that we must pay heed to cool intellect rather than hot passion.Such skepticism of our claim to know might make one hesitant to engage in the enigmatic world—but we have no choice! In order to find our hybrid daimon, both Socratic and pragmatic, Schollmeier suggests rhetoric as the methodology best suited to serving practical knowledge because it eschews certainty in favor of probability and acknowledges that the hypotheses on which we act are tentative and revisable. To this end, Schollmeier highlights the enthymeme and argument by example as the two techniques that best suit the nature of our hypothetical knowledge, and he urges a return to philodoxy, the love of opinion.Giving up our claim to certainty need not be a dismal proposition. Having established his methodology, Schollmeier begins building a moral philosophy that embraces an ontology of change and contends that our happiness provides us with stability in the form of a rational teleology. The objects of our human happiness are fleeting and changeable, so happiness cannot be static but is, rather, an activity that is its own end, "an activity that is an intellectual inquiry" (78). Our happiness is contingent on our ability to hypothetically determine, in our particular setting, our function and then fulfill this role to the best of our abilities. Depending on the setting, it may be dancing, parenting, or simply a lively... (shrink)

Therefore, the visual arts are a homeground of visual thinking. 1A common misconception about the nature of art and of aesthetic appreciation is that these activities are essentially (...) a question of "feeling," as if tuning in to the right feeling will automatically lead to a full understanding of the work of art. Another widespread misunderstanding essentially reduces art viewing to a simple question of perception, as if looking long and hard isalways enough to apprehend the work of art's message. Fortunately, a growing body of research into adults' art viewing experiences is debunking these widely held beliefs as oversimplifications of the art viewing process. We can now assert, with a good degree of certainty, that our art viewing experiences solicit four key areas: the affective, perceptual, communicative, and cognitive dimensions of human experiencing. 2 Therefore, we would be hard-pressed not to agree with Rudolph Arnheim's reflections, presented above, on the important role of thought in shaping our artistic and aesthetic experiences.While acknowledging at the outset the essential roles of affect, perception, and communication in our art viewing experiences, this paper focuses more specifically on aspects of the intellectual dimension of this experience. First, we will present and discuss a model that we have developed over the last several years. This model identifies the kinds of knowledge and learning involved in art viewing activities. Second, we will present the results of an empirical study conducted to provide support for the model. Finally we will briefly discuss the model's usefulness for the purposes of aesthetic education. [End Page 78] The Model of Aesthetic Understanding as Informed Experience The Model of Aesthetic Understanding as Informed Experience provides an explanation of the process of understanding and appreciating a work of art from an educational perspective: it identifies the types of knowledge involved and it also pinpoints the kinds of learning at each stage in the process leading to an understanding of the aesthetic object.In this model, the process of viewing and understanding a work of art is visualized as a two-phased type of informed experience. Through a process of experiential learning, the viewer first encounters the work of art and formulates an initial interpretation. Then, through a process involving theoretical learning, the viewer compares his or her first interpretation with a related body of external, scientific information. This second step in the learning process leads to a reconstruction of knowledge about the work of art. Tandem use of the two processes assists the viewer in furthering his or her understanding of the art object; it also promotes growth in his or her art viewing skills. In the course of each new encounter with an aesthetic object, the interplay of experiential and theoretical learning leads to additional development of the viewer's background knowledge in art, resulting in better preparedness to successfully engage the next work of art. 4 Theoretical Foundations of the Model Three different theories informed the development of the model. 5 By using anecdotal evidence obtained from a group of fifty-two museum professionals, Mihaly Csikszentmihalyi and Rick E.Robinson were able to identify the four major dimensions of aesthetic experience: intellect, communication, perception, and emotion.

Genia Schönbaumsfeld argues that Cartesian skepticism is an illusion induced by the “Cartesian Picture” of perceptual knowledge, in which knowledge of the “external world” depends on an inference from how things subjectively seem to one to how they actually are. To show its incoherence, she draws on the work of John McDowell, which she sees as elaborating a central theme from Wittgenstein’s On Certainty. I argue that Cartesian skepticism is not an illusion, as Schönbaumsfeld understands ‘illusion’, and that (...) McDowell’s account of perceptual knowledge is both untenable and incompatible with Wittgenstein’s ideas about knowledge. Schönbaumsfeld thinks that, to understand how perception can engender knowledge of the world, we need a non-Cartesian account of perceptual reasons. Wittgenstein offers a much more radical break with the Cartesian Picture: an account of knowledge without ‘experience’. (shrink)

Steven Lehar allows too much to his direct realist opponent in using the word “subjective” of the sensory field per se. The latter retains its nonconceptual, nonmental nature even when explored by perceptual judgement. He also needs to stress the evolutionary value of perceptual differences between person and person, a move that enables one to undermine the direct realist's superstitious certainty about the singular object.

In lieu of an abstract, here is a brief excerpt of the content:“No One Is Psychotic in My Presence”S. Nassir Ghaemi (bio)Keywordsexistentialism, Semrad, delusions, psychosis, empathy, HavensWe are all prone to make wrong judgments about others (and ourselves) based on inaccurate (or insufficient) information. I recently had this experience with a relative, who cited a number of behaviors as reasons for him to make a rather harsh judgment about my internal mental states. Before hearing his rationale—and despite my belief that (...) he was wrong—I had to reserve some doubt that I might, unconsciously, have those disagreeable habits that my kind relative ascribed to me. But after I heard his explanation, the only possibility that seemed to fit was psychosis (in him, not me); because I was rather certain that he did not have a psychotic illness, I had to conclude that he had beliefs that served his own purposes in some way, although they were simply wrong.We all do this, all the time (perhaps this is the source of the wisdom behind a peasant woman’s admonition to Maxim Gorky: “Remember, above all, do not judge: that is the Devil’s work” [Gorky 1949]).But we do not all have delusions, at least in the sense that delusions are supposed to mark out psychiatric illnesses. Rhodes and Gipps (2008) make this point in their critique of cognitive theories of delusion: “One (‘rationalist’) line of research has explored to what extent people with psychotic delusions may have a malfunction in their reasoning processes (Garety and Hemsley 1994). Another (‘empiricist’) approach has it that delusions are a product of normal reasoning processes running on data provided by abnormal perceptual experiences (Maher 1988, 1999).” Both approaches identify abnormal kinds of reasoning in persons with psychosis, most of which are shared with the normal population (like my relative). But: “the question needs to be asked as to why, in many cases, clear counter-evidence has no effect in correcting the delusional belief. Confirmation bias after all itself only explains why people may not look for disconfirming evidence (Wason 1968), and does not explain why people may fail to believe it when they happen upon or are presented with it” (Rhodes and Gipps 2008, 306).This gets to the distinction between non-bizarre and bizarre delusions (a distinction that the authors do not make in their paper): Non-bizarre delusions seem completely explainable on cognitive grounds—they are not incredibly irrational (my relative’s perspective is logically plausible), yet they are just wrong (it is empirically false, I think). (Another example: I could plausibly believe that the FBI has me—a Shiite Muslim Middle Eastern male who hails from the Axis of Evil—under surveillance; it would simply be false, or not). On the other hand, the authors’ examples of delusions are both bizarre and wrong at first glance, not because they are illogical (in their conceptual associations), but simply because they just seem wrong without [End Page 315] much need to explain why (unlike my relative’s theories): “What, then, needs accounting for is why deluded persons do not themselves recognize the following: the unlikeliness of their belief, the insufficiency of the grounds they provide, the unlikeliness of their premises when they provide them (as well as their conclusions), the greater likelihood that the evidence they adduce was (for example) hallucinated rather than perceived, and so on” (Rhodes and Gipps 2008, 297).The authors turn first to Ludwig Wittgenstein, then John Searle—the former for the notion that we have “Bedrock certainties” that are founded on having served us in acting in the world (these beliefs do not require rational or empirical justification), the latter for the notion of a Background “defined as those abilities and dispositions which themselves are neither representations nor rules, yet that we need to hypothesize as functioning before we can make sense of everyday perception, thinking and language” (Searle 1995, 129). Go mow the lawn, we say, presuming that scissors will not be used:The capacity to discern what counts as the relevant context is itself a Background capacity that cannot, on pains of an infinite regress of an infinity of disambiguations, be understood as consisting in further propositional knowledge. The cultural ‘common sense... (shrink)
