An overview of the epistemology of perception, covering the nature of justification, immediate justification, the relationship between the metaphysics of perceptual experience and its rational role, the rational role of attention, and cognitive penetrability. The published version will contain a smaller bibliography, due to space constraints in the volume.

If our experiences are cognitively penetrable, they can be influenced by our antecedent expectations, beliefs, or other cognitive states. Theorists such as Churchland, Fodor, Macpherson, and Siegel have debated whether and how our cognitive states might influence our perceptual experiences, as well as how any such influences might affect the ability of our experiences to justify our beliefs about the external world. This article surveys views about the nature of cognitive penetration, the epistemological consequences of denying cognitive penetration, and the (...) epistemological consequences of affirming cognitive penetration.

This is a much shorter version of our entry on the Epistemology of Perception, which will be published in the Oxford Handbook for the Philosophy of Perception in 2013. The longer version has far more references in it, whereas this version is pared down to the essentials.

Plantinga famously argues against evidentialism that belief in God can be properly basic. But the epistemology of cognitive faculties such as perception and memory which produce psychologically non-inferential beliefs shows that various inferentially justified theoretical beliefs are epistemically prior to our memory and perceptual beliefs, preventing the latter from being epistemically basic. Plantinga's analogy between the sensus divinitatis and these cognitive faculties suggests that the deliverances of the sensus divinitatis cannot be properly basic either. Objections by and on (...) behalf of Plantinga to this argument are considered. (shrink)

Some argue that Candrakīrti is committed to rejecting all theories of perception in virtue of the rejection of the foundationalisms of the Nyāya and the Pramāṇika. Others argue that Candrakīrti endorses the Nyāya theory of perception. In this paper, I will propose an alternative non-foundationalist theory of perception for Candrakīriti. I will show that Candrakrti’s works provide us sufficient evidence to defend a typical Prāsagika’s account of perception that, I argue, complements his core non-foundationalist ontology.

Is perception cognitively penetrable, and what are the epistemological consequences if it is? I address the latter of these two questions, partly by reference to recent work by Athanassios Raftopoulos and Susanna Seigel. Against the usual, circularity, readings of cognitive penetrability, I argue that cognitive penetration can be epistemically virtuous, when---and only when---it increases the reliability of perception.

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was also (...) very influential in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

In this paper I argue for a version of the Total Evidence view according to which the rational response to disagreement depends upon one's total evidence. I argue that perceptual evidence of a certain kind is significantly weightier than many other types of evidence, including testimonial. Furthermore, what is generally called "The Uniqueness Thesis" is actually a conflation of two distinct principles that I dub "Evidential Uniqueness" and "Rationality Uniqueness." The former principle is likely true but the latter almost certainly (...) false. Seeing why the Rationality Uniqueness fails opens the door to seeing how mutual reasonable disagreement is possible even among those who share the same evidence. (shrink)

This article responds to two arguments against ‘Epistemic Perceptualism’, the view that emotional experiences, as involving a perception of value, can constitute reasons for evaluative belief. It first provides a basic account of emotional experience, and then introduces concepts relevant to the epistemology of emotional experience, such as the nature of a reason for belief, non-inferentiality, and prima facie vs. conclusive reasons, which allow for the clarification of Epistemic Perceptualism in terms of the Perceptual Justificatory View. It then (...) challenges two arguments which purport to show that emotional experience is not a source of reasons for evaluative belief. The first argument claims that because normative why-questions are always appropriate in the case of emotions, then emotions can never be conclusive reasons for corresponding evaluative beliefs. The second purports to show that appeal to emotional experience as a source of reasons for evaluative beliefs renders emotions problematically self-justifying, and since emotions cannot be self-justifying, they cannot provide any sort of reason for corresponding evaluative beliefs. This article responds to these arguments, and in doing so shows there is still much to be learned about the epistemology of emotional experience by drawing analogies with perceptual experience.

Suppose our visual experiences immediately justify some of our beliefs about the external world — that is, justify them in a way that does not rely on our having independent reason to hold any background belief. A key question now arises: Which of our beliefs about the external world can be immediately justified by experiences? I address this question in epistemology by doing some philosophy of mind. In particular, I evaluate the following proposal: if your experience e immediately justifies (...) you in believing that p , then (i) e has the content that p , and (ii) e ’s having the content that p is fixed by what it is like to have e . I start by clarifying this proposal and surveying the case in its favour. I then argue against the proposal and develop an alternative. The discussion shows what role visual consciousness plays and does not play in the justification of perceptual beliefs. (shrink)

This paper proposes some guidelines for the undeveloped discussion of auditory epistemology. Auditory epistemology is an approach concerned with the perceptual basis for knowledge and belief, specifically around audition. The article pursues two goals. Firstly, it claims that addressing auditory perception from the viewpoint of epistemology is more fruitful than the discussion on phenomenology which has thus far dominated the debates in the literature on sound. Secondly, it elaborates a concrete proposal pertaining to the cooperation of (...) sense-modalities. In so doing, a model for “Perceptual Coherence” is suggested. The first section of the paper critically reviews the problem of perception as it is usually understood in traditional epistemology. An ensuing section outlines the model of perceptual coherence.

Perception is typically distinguished from cognition. For example, seeing is importantly different from believing. And while what one sees clearly influences what one thinks, it is debatable whether what one believes and otherwise thinks can influence, in some direct and non-trivial way, what one sees. The latter possible relation is the cognitive penetration of perception. Cognitive penetration, if it occurs, has implications for philosophy of science, epistemology, philosophy of mind, and cognitive science. This paper offers an analysis (...) of the phenomenon, its theoretical consequences, and a variety of experimental results and possible interpretations of them. The paper concludes by proposing some constraints for analyses and definitions of cognitive penetrability. (shrink)

This chapter concerns the cognitive penetration of the visual experience of colour. Alleged cases of cognitively penetrated colour perception are of special import since they concern an uncontroversial type of visual experience. All theorists of perception agree that colour properties figure properly in the content or presentation of visual perception, even though not all parties agree that pine trees or causes or other "high-level" properties can figure properly in visual content or presentation. So an alleged case of (...) this kind does not require controversial commitments regarding the admissible contents of visual perception. The chapter clarifies this theoretical importance , identifying alleged empirical cases of cognitively penetrated colour perception, and then analyzing the implications of such cases for an epistemology of perception.

We show how an epistemology informed by cognitive science promises to shed light on an ancient problem in the philosophy of mathematics: the problem of exactness. The problem of exactness arises because geometrical knowledge is thought to concern perfect geometrical forms, whereas the embodiment of such forms in the natural world may be imperfect. There thus arises an apparent mismatch between mathematical concepts and physical reality. We propose that the problem can be solved by emphasizing the ways in which (...) the brain can transform and organize its perceptual intake. It is not necessary for a geometrical form to be perfectly instantiated in order for perception of such a form to be the basis of a geometrical concept. (shrink)

What is the biological function of perception? I hold perception, especially visual perception in humans, has the biological function of accurately representing the environment. Tyler Burge argues this cannot be so in Origins of Objectivity (Oxford, 2010), for accuracy is a semantical relationship and not, as such, a practical matter. Burge also provides a supporting example. I rebut the argument and the example. Accuracy is sometimes also a practical matter if accuracy partly explains how perception contributes (...) to survival and reproduction. (shrink)

It seems possible to know that a mathematical claim is necessarily true by inspecting a diagrammatic proof. Yet how does this work, given that human perception seems to just (as Hume assumed) ‘show us particular objects in front of us’? I draw on Peirce’s account of perception to answer this question. Peirce considered mathematics as experimental a science as physics. Drawing on an example, I highlight the existence of a primitive constraint or blocking function in our thinking which (...) we might call ‘the hardness of the mathematical must’. (shrink)

Maps provide us with an easily recognizable version of the new demarcation problem: On the one hand, we are all familiar with graphics and maps that unacceptably distort our perceptions without being technically inaccurate or fictive; indeed there are whole websites groups devoted to curating such images for fun. On the other hand, there are multiple unavoidably value-laden choices that must be made in the production of any map. Producing a map requires choosing everything from the colors and thicknesses of (...) the lines, the scale, the projection system, the categories and parameters represented, and much more. There is no neutral default for any of these choices, and all of them shape what information the map communicates. All the visual choices involved in producing a map enable some information to be conveyed at the cost of hiding or distorting other information, as map makers themselves routinely acknowledge and discuss. Hence there are no straightforward answers to questions about the line between distortion and legitimate representational choices. I explore three distinctive kinds of epistemic risks in map-making that generate special versions of the demarcation problem, which I dub aesthetic risk, categorization risk, and simplification risk. I argue that in each case, even good maps – maps that are accurate and epistemically valuable – have the potential to mislead us. I end by looking at maps that offer special epistemic benefits by making clear their own lack of value-neutrality while still being accurate and epistemically fecund. (shrink)

The theory-ladenness of perception argument is not an argument at all. It is two clusters of arguments. The first cluster is empirical. These arguments typically begin with a discussion of one or more of the following psychological phenomena: (a) the conceptual penetrability of the visual system, (b) voluntary perceptual reversal of ambiguous figures, (c) adaptation to distorting lenses, or (d) expectation effects. From this evidence, proponents of theory-ladenness typically conclude that perception is in some sense "laden" with theory. (...) The second cluster attempts to extract deep epistemological lessons from this putative fact. Some philosophers conclude that science is not (in any traditional sense) a rational activity, while others conclude that we must radically reconceptualize what scientific rationality involves. Once we understand the structure of these arguments, much conventional wisdom about the significance of the psychological data turns out to be false. (shrink)

Plato’s Theory of Perception This research deals with Plato's perceptual theory, as the perceptual theory in Plato's philosophy represents one of the steps of the Plato’s epistemology. Plato divided knowledge into four categories: Sensory knowledge, presumptive knowledge, mathematical knowledge, and rational knowledge. The theory of sensory perception is in the first place, so this research focuses on the statements, the meaning of perception, the senses, the difference between sensation and mind, the topics of sensory perception, (...) and the nature of the work of sensory perception.

Philosophy and Phenomenological Research, EarlyView.

I argue that perceptual content involves representations both of aspects of objects, and of objects themselves, whether at the level of conscious perception, or of low-level perceptual processing - a double content structure. I present an 'orientational' theory of the relations of the two kinds of perceptual content, which can accommodate both the general semantic possibility of perceptual misrepresentation, and also species of it involving characteristic perceptual confusions of aspectual and intrinsic content. The resulting theoretical structure is argued to (...) be a broadly methodological or logical one, rather than a substantive theory that is open to empirical refutation. (shrink)

Last year saw the 20th anniversary edition of JECP, and in the introduction to the philosophy section of that landmark edition, we posed the question: apart from ethics, what is the role of philosophy ‘at the bedside’? The purpose of this question was not to downplay the significance of ethics to clinical practice. Rather, we raised it as part of a broader argument to the effect that ethical questions – about what we should do in any given situation – are (...) embedded within whole understandings of the situation, inseparable from our beliefs about what is the case, what it is that we feel we can claim to know, as well as the meaning we ascribe to different aspects of the situation or to our perception of it. Philosophy concerns fundamental questions: it is a discipline requiring us to examine the underlying assumptions we bring with us to our thinking about practical problems. Traditional academic philosophers divide their discipline into distinct areas that typically include logic: questions about meaning, truth and validity; ontology: questions about the nature of reality, what exists; epistemology: concerning knowledge; and ethics: how we should live and practice, the nature of value. Any credible attempt to analyse clinical reasoning will require us to think carefully about these types of question and the relationships between them, as they influence our thinking about specific situations and problems. So, the answers to the question we posed, about the role of philosophy at the bedside, are numerous and diverse, and that diversity is illustrated in the contributions to this thematic edition.

Clearly we can perceive both objects, and various aspects or appearances of those objects. But how should that complexity of perceptual content be explained or analyzed? I argue that perceptual representations normally have a double or two level nested structure of content, so as to adequately incorporate information both about contextual aspects Y(X) of an object X, and about the object X itself. On this double content (DC) view, perceptual processing starts with aspectual data Y?(X?) as a higher level of (...) content, which data does not itself provide lower level X-related content, but only an aspectually encoded form of such data. Hence the relevant perceptual data Y?(X?) must be. (shrink)

This paper examines an ancient debate over the rationality of perception. What leads the Stoics to affirm, and the Epicureans to deny, that to form a sense-impression is an activity of reason? The answer, we argue, lies in a disagreement over what is required for epistemic success. For the Stoics, epistemic success consists in believing the right propositions, and only rational states, in virtue of their predicational structure, put us in touch with propositions. Since they identify some sense-impressions as (...) criteria of truth and thus as the basis for epistemic success, the Stoics maintain that sense-impressions must be rational. The Epicureans agree with the Stoics that sense-impressions function as criteria of truth, and also agree broadly on what it means for a state to be rational, but deny that sense-impressions are rational because (1) they think that epistemic success must be supported by a state that is necessarily error-free and (2) accept that rational states can be false. In reconstructing this debate, we refine the standard interpretation of the fundamental difference between Epicurean and Stoic epistemology and also develop parallels with epistemological debates today. One upshot is a more nuanced appreciation of the merits of Epicurean epistemology vis-à-vis the Stoics. (shrink)

This paper explores the epistemological significance of the view that we can literally see, hear, and touch evaluative properties (the high-level theory of value perception). My central contention is that, from the perspective of epistemology, the question of whether there are such high-level experiences doesn’t matter. Insofar as there are such experiences, they most plausibly emerged through the right kind of interaction with evaluative capacities that are not literally perceptual (e.g., of the sort involved in imaginative evaluative reflection). (...) But even if these other evaluative capacities turn out not to alter the content of perceptual experience, they would still be sufficient to do all of the justificatory work that high-level experiences are meant to do. I close by observing that it may matter a great deal whether a certain other picture of value perception is true. This alternative picture has it that desires and/or emotions are perceptual-like experiences of value. (shrink)

This paper investigates the nature of reality by looking at the philosophical debate between realism and idealism and at scientific investigations in quantum physics and at recent studies of animal senses, neurology and cognitive psychology. The concept of perceptual relativity is examined and this involves looking at sense perception in other animals and various examples of perceptual relativity in science. It will be concluded that the universe is observer dependent and that there is no reality independent of the observer, (...) which is knowable to the observer. The paper concludes by an investigation of what an observer dependent universe would be like and that recognition of an observer dependent world would lead to a more open minded and tolerant world.

Much mainstream analytic epistemology is built around a sceptical treatment of modality which descends from Hume. The roots of this scepticism are argued to lie in Hume’s (nominalist) theory of perception, which is excavated, studied and compared with the very different (realist) theory of perception developed by Peirce. It is argued that Peirce’s theory not only enables a considerably more nuanced and effective epistemology, it also (unlike Hume’s theory) does justice to what happens when we appreciate (...) a proof in mathematics.

Reductionism about testimony holds that testimonial warrant or entitlement is just a species of inductive warrant. Anti-Reductionism holds that it is different from inductive but analogous to perceptual or memorial warrant. Perception receives much of its positive epistemic status from being reliably truthconducive in normal conditions. One reason to reject the epistemic analogy is that testimony involves agency – it goes through the will of the speaker – but perception does not. A speaker might always choose to lie (...) or otherwise deliberately mislead. It is argued that the force of this derives (in part) from Libertarianism about agency, and that Libertarianism, if it undermines the Anti-Reductionist explanation of why we are entitled to rely upon testimony, undermines the Reductionist explanation as..

This chapter has two objectives. The first is to clarify Aristotle’s view of the first principles of the sciences. The second is to stake out a critical position with respect to this view. The paper sketches an alternative to Aristotle’s intuitionism based in part on the use of quantitative inductive logics.

Dispositionalism is the theory of modality that grounds all modal truths in powers: all metaphysically possible and necessary truths are to be explained by pointing to some actual power, or absence thereof. One of the main reasons to endorse dispositionalism is that it promises to deliver an especially desirable epistemology of modality. However, so far this issue has not be fully investigated with the care it is due. The aim of this paper is to fill this gap. We will (...) cast some doubts on whether the dispositionalist really is in a better position to explain our modal knowledge. In fact, we argue that there is a tension between some core tenets of a powers metaphysics and the very features that make dispositionalism the ideal backdrop for a desirable epistemology of modality. We conclude that this leaves dispositionalists who want to deliver the promised epistemology with a hard, currently unfulfilled, task. (shrink)

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and (...) brain stimulation). They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs. They thus hypothesized that folk intuitions better align with a no blocker condition than with a causal condition. This paper continues this line of enquiry with two new experiments. The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition. They also provide an empirical reason to doubt the reflection defense. (shrink)

Disjunctivist views in the theory of perception hold that genuine perceptions differ in some relevant kind from misperceptions, such as illusions and hallucinations. In recent papers, Tyler Burge has argued that such views conflict with the basic tenets of perceptual psychology. According to him, perceptual psychology is committed to the view that genuine perceptions and misperceptions produced by the same proximal stimuli must be or involve perceptual states of the same kind. This, he argues, conflicts with disjunctivism. In this (...) paper, I defend epistemological disjunctivism from Burge’s inconsistency charge. To this end, I survey the perceptual psychological literature, and reveal that the perceptual kinds they tend to employ differ from and imply nothing about the kinds at issue for the epistemological disjunctivist. I then argue that Burge’s concerns with epistemological disjunctivism are best interpreted as motivated not by his commitment to empirical science, but instead by his views in epistemology and about human rationality.

We enjoy immediate knowledge of our own limbs and bodies. I argue that this knowledge, which is also called proprioception, is a special form of perception, special in that it is, unlike perception by the external senses, at the same time also a form of genuine self-knowledge. The argument has two parts. Negatively, I argue against the view, held by G. E. M. Anscombe and strengthened by John McDowell, that this knowledge, bodily self-knowledge, is non-perceptual. This involves, inter (...) alia, rescuing from McDowell’s attack the very idea of receptive self-knowledge. On the positive side, I develop, by drawing on the work of Brian O’Shaughnessy, a detailed account of bodily self-knowledge as a special form of perception. This account spells out how this special form of perception is epistemologically mediated by sensations of a special class of primary qualities—vital-dynamic sensations as I call them—in one’s limbs. (shrink)

It is widely assumed that perception is a source of reasons (SR). There is a weak sense in which this claim is trivially true: even if one characterizes perception in purely causal terms, perceptual beliefs originate from the mind's interaction with the world. When philosophers argue for (SR), however, they have a stronger view in mind: they claim that perception provides pre- or non-doxastic reasons for belief. In this article I examine some ways of developing this view (...) and criticize them. I exploit these results to formulate a series of constraints that a satisfactory account of the epistemic role of perception should fulfil. I also make a positive suggestion: coherentists are right when they claim that only beliefs can be reasons for other beliefs. Nevertheless, I depart from traditional coherentism, for I do not buy its conception of perception as bare sensation, nor explicate the justificatory status of beliefs in terms of coherence. My point is rather that, when one invokes experience to justify a belief, the justifying state must have structural features of beliefs. (shrink)

Almost everyone agrees that many testimonial beliefs constitute knowledge. According to non-reductionists, some testimonial beliefs possess positive epistemic status independent of that conferred by perception, memory, and induction.

Outside of philosophy, ‘intuition’ means something like ‘knowing without knowing how you know’. Intuition in this broad sense is an important epistemological category. I distinguish intuition from perception and perception from perceptual experience, in order to discuss the distinctive psychological and epistemological status of evaluative property attributions. Although it is doubtful that we perceptually experience many evaluative properties and also somewhat unlikely that we perceive many evaluative properties, it is highly plausible that we intuit many instances of evaluative (...) properties as such. The resulting epistemological status of evaluative property attributions is very much like it would be if we literally perceived such properties. (shrink)

This dissertation examines the theory of perceptual cognition laid out by the 7th century Buddhist scholar, Dharmakīrti, in his magnum opus, the Pramāṇavārttika. Like most theories of perception, both ancient and modern, the sensory cognition of ordinary objects is a topic of primary concern. Unlike other theorists, however, Dharmakīrti advances a technical definition of “perception” as a cognition which is both nonconceptual and non-erroneous. Dharmakīrti’s definition of perception is thereby deliberately inclusive of three additional types of “perceptual” (...) cognition, in addition to veridical sensory awareness: the nonconceptual mental apprehension of an immediately-preceding cognition (“mental perception”), the vivid appearance of soteriologically efficacious objects of contemplative practice (“yogic perception”), and the sheer unmediated presence of the contents of cognition—whatever these might be—to the cognizing mind (“reflexive awareness”). Through the logical examination of what it means to be aware of an object, Dharmakīrti demonstrates that the awareness of an object is just the awareness of a phenomenal form or cognitive image produced by that object. Pursuing this analysis further, however, Dharmakīrti argues that the very notion of an object of cognition that exists “externally” or outside the mind is incoherent. Additionally, Dharmakīrti maintains that the phenomenological structure of subject and object—that is, the “first-personal” sense of one’s own cognitions as pertaining to oneself (“for-me-ness”), together with the inseparably concomitant sense that the objects of cognition exist “out there” in an extramental world—is strictly a form of cognitive error. Therefore, because ordinary sensory cognition is inherently structured by this subject-object duality, ordinary sensory cognition must in the final analysis be understood as erroneous. According to Dharmakīrti, in other words, ultimately only the nondual “luminosity” of reflexive awareness is genuinely perceptual, because only reflexive awareness is undistorted by nature. In this way, Dharmakīrti’s epistemology provides a theoretical foundation for the advanced nondual contemplative practices of Indian and Tibetan Buddhism, particularly Mahāmudrā and rDzogs chen.

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.

This chapter is organized around four central questions about the role of reasons in the epistemology of perception. The 'whether?' question: does perception provide us with reasons for belief about the external world? The 'how?' question: how does perception provide us with reasons for belief about the external world? The 'when?' question: when does perception provide us with reasons for belief about the external world? The 'what?' question: what are the reasons that perception provides (...) us with for belief about the external world? (shrink)

I argue that we should question the orthodox way of thinking about epistemological disjunctivism. I suggest that we can formulate epistemological disjunctivism in terms of states of seeing things as opposed to states of seeing that p. Not only does this alternative formulation capture the core aspects of epistemological disjunctivism as standardly formulated, it has two salient advantages. First, it avoids a crucial problem that arises for a standard formulation of epistemological disjunctivism—the basis problem. And second, it is less committed (...) than standard formulations are in the metaphysics of perception. (shrink)

In this paper, I put forward an argument for the view that emotional responses of esteem to perceived demonstrations of good character represent the perceived character traits as valuable, and hence, as virtues. These esteeming experiences are analogous to perceptual representations in other modalities in their epistemic role as causing, providing content for and justifying beliefs regarding the value of the traits they represent. I also discuss the role that the perceiver’s own character plays in their ability to recognize and (...) respond appropriately to virtue in others, showing that moral virtues are also epistemic virtues when it comes to facilitating knowledge about the character of people we encounter.

Six hundred three people completed a survey measuring perceptions of traditional areas of philosophical inquiry and their relationship to empirical science. The ten areas studied were: aesthetics, epistemology, ethics, history of philosophy, logic, metaphysics, philosophy of language, philosophy of mind, philosophy of science, and political philosophy. For each area, participants rated whether it is currently central to philosophy, whether its centrality depends on integration with science, and whether work in the area is sufficiently integrated with science. Centrality judgments tended (...) to be high. Participants viewed nine of the ten areas as central to philosophy, although they made this judgment more confidently for some areas. Dependence judgments were more varied, ranging from clear disagreement to clear agreement. Integration judgments were also varied but exhibited more uncertainty. Some areas whose centrality depended on integration were judged to be well integrated, but a central tendency for all other areas was ambivalence. Demographic factors had small but statistically significant effects on all three sorts of judgment. Higher age predicted higher centrality judgments and higher integration judgments. Higher socioeconomic status predicted lower dependence judgments and higher integration judgments. Men recorded higher integration judgments. (shrink)

This is a very selective survey of developments in epistemology, concentrating on work from the past twenty years that is of interest to philosophers of science. The selection is organized around interesting connections between distinct themes. I first connect issues about skepticism to issues about the reliability of belief-acquiring processes. Next I connect discussions of the defeasibility of reasons for belief to accounts of the theory-independence of evidence. Then I connect doubts about Bayesian epistemology to issues about the (...) content of perception. The last detailed connection is between considerations of the finiteness of cognition and epistemic virtues. To connect the connections I end by briefly discussing the pressure that consideration of social roles in the transmission of belief puts on the purposes of epistemology. (shrink)

A belief in a firm correspondence between objects, ideas, and their representation in language pervaded the works of Anne Robert Jacques Turgot

(1727–1781) in 1750. This conviction is particularly manifest in Turgot’s sharp critique of Berkeley’s philosophical system and his remarks on Maupertuis’s reconstruction of the origin of language. During the 1750s Turgot’s epistemological views underwent a change, apparent in two of his contributions to the Encyclopédie: the entries Existence and Étymologie (1756). These articles included a reassessment of Berkeleyan immaterialism, facing (...) an ultimate crisis of definition and representation. A similar development may be traced in contemporary works by Condillac and Diderot. Turgot’s Encyclopédie entries also envisaged a new science, an archeology of the human mind aided by the examination of linguistic development and change. This entailed the scientific verification of conjectures in any historical account of ideas, turning etymological

and psychological inquiries into what Turgot termed ‘experimental metaphysics’. (shrink)

Zero provides a challenge for philosophers of mathematics with realist inclinations. On the one hand it is a bona fide cardinal number, yet on the other it is linked to ideas of nothingness and non-being. This paper provides an analysis of the epistemology and metaphysics of zero. We develop several constraints and then argue that a satisfactory account of zero can be obtained by integrating an account of numbers as properties of collections, work on the philosophy of absences, and (...) recent work in numerical cognition and ontogenetic studies.

A number of philosophers have found inspiration for a distinctive approach to a wide range of epistemological issues in P. F. Strawson’s classic essay, “Freedom and Resentment.” These Strawsonian epistemologists, as I call them, argue that the epistemology of testimony, self-knowledge, promising, and resolving is fundamentally different in kind from the epistemology of perception or inference. We should not see properly formed belief on these topics as evidence-based, for such an objective perspective, in such cases, results in (...) a kind of alienation. This paper explores these Strawsonian themes in recent epistemology, and argues that the Strawsonian approach should be resisted. (shrink)

How does an audience receive a work of art? Does the experience only affect the viewer or does it have an effect and thus influence his or her actions? It is the cultural philosopher Ernst Cassirer and his successors in philosophy and developmental psychology as well as in neuroscience to this day who postulate that perception in general and perception of art in particular are not neutral in their origins but alive and thus meaningful. They assume that both (...) are based on analogous principles: in the perception of moving forms and spatial forms in the world and rhythms of forms, colors, light and shadow in art. In practice, this means that perception and its felt effects have an effect on the feelings of the viewer and thus help him to inform himself directly and intensively about the world through art. In contrast to this general epistemological aesthetic theory, which philosophers in particular accept, it is to be shown that this assumption must be redefined not with reference to the world, but with reference to art and design. For the latter, the approach will be extended to a semiotic theory. The background is that in contrast to the world, the designed forms and thus the designed intentions of the artist and designer or his client in relation to the chosen theme have an impact on the viewer and thus on culture and its communicative dynamics.

It is generally accepted that sight—the capacity to see or to have visual experiences—has the power to give us knowledge about things in the environment and some of their properties in a distinctive way. Seeing the goose on the lake puts me in a position to know that it is there and that it has certain properties. And it does this by, when all goes well, presenting us with these features of the goose. One might even think that it is (...) part of what it is to be a perceptual capacity that it has this kind of epistemological power, such that a capacity that lacked this power could not be perceptual. My focus in this essay is the sense of taste—the capacity to taste things or to have taste experiences. It has sometimes been suggested that taste lacks sight-like epistemological power. I argue that taste has epistemological power of the same kind as does sight, but that as a matter of contingent fact, that power often goes unexercised in our contemporary environment. We can know about things by tasting them in the same kind of way as we can know about things by seeing them, but we often do not. I then consider the significance of this conclusion. I suggest that in one way, it matters little, because our primary interest in taste is not epistemic but aesthetic. But, I end by suggesting, it can matter ethically. (shrink)
