As I head home from work, I’m not sure whether my daughter’s new bike is green, and I’m also not sure whether I’m on drugs that distort my color perception. One thing that I am sure about is that my attitudes towards those possibilities are evidentially independent of one another, in the sense that changing my confidence in one shouldn’t affect my confidence in the other. When I get home and see the bike it looks green, so I increase my (...) confidence that it is green. But something else has changed: now an increase in my confidence that I’m on color-drugs would undermine my confidence that the bike is green. Jonathan Weisberg and Jim Pryor argue that the preceding story is problematic for standard Bayesian accounts of perceptual learning. Due to the ‘rigidity’ of Conditionalization, a negative probabilistic correlation between two propositions cannot be introduced by updating on one of them. Hence if my beliefs about my own color-sobriety start out independent of my beliefs about the color of the bike, then they must remain independent after I have my perceptual experience and update accordingly. Weisberg takes this to be a reason to reject Conditionalization. I argue that this conclusion is too pessimistic: Conditionalization is only part of the Bayesian story of perceptual learning, and the other part needn’t preserve independence. Hence Bayesian accounts of perceptual learning are perfectly consistent with potential underminers for perceptual beliefs. (shrink)

Seeing a red hat can (i) increase my credence in the hat is red, and (ii) introduce a negative dependence between that proposition and po- tential undermining defeaters such as the light is red. The rigidity of Jeffrey Conditionalization makes this awkward, as rigidity preserves inde- pendence. The picture is less awkward given ‘Holistic Conditionalization’, or so it is claimed. I defend Jeffrey Conditionalization’s consistency with underminable perceptual learning and its superiority to Holistic Conditionalization, arguing that the latter (...) is merely a special case of the former, is itself rigid, and is committed to implausible accounts of perceptual con- firmation and of undermining defeat.

Perceptual representations pick out individuals and attribute properties to them. This paper considers the role of perceptual attribution in determining or guiding perceptual reference to objects. We consider three extant models of the relation between perceptual attribution and perceptual reference–all attribution guides reference, no attribution guides reference, or a privileged subset of attributions guides reference–and argue that empirical evidence undermines all three. We then defend a flexible-attributives model, on which the range of perceptual attributives (...) used to guide reference shifts adaptively with context. This model underscores the remarkable and dynamic intelligence of our perceptual capacities. We elucidate implications of the model for the boundary between perception and propositional thought.

Perceptual modalities have been traditionally considered the product of dedicated biological systems producing information for higher cognitive processing. Psychological and neuropsychological evidence is offered which undermines this point of view and an alternative account of modality from the enactive approach to understanding cognition is suggested. Under this view, a perceptual modality is a stable form of perception which is structured not just by the biological sensitivities of the agent, but by their goals and the set of skills or (...) expertise which they are deploying at a given time. Such a view suggests that there is no such thing as an experience that is purely visual, auditory, or otherwise modal and that our attempts to understand consciousness and the mind must be conducted within a framework that provides an account of embodied, goal-directed adaptive coping with the world.

Theories of consciousness divide over whether perceptual consciousness is rich or sparse in specific representational content and whether it requires cognitive access. These two issues are often treated in tandem because of a shared assumption that the representational capacity of cognitive access is fairly limited. Recent research on working memory challenges this shared assumption. This paper argues that abandoning the assumption undermines post-cue-based “overflow” arguments, according to which perceptual conscious is rich and does not require cognitive access. Abandoning (...) it also dissociates the rich/sparse debate from the access question. The paper then explores attempts to reformulate overflow theses in ways that don’t require the assumption of limited capacity. Finally, it discusses the problem of relating seemingly non-probabilistic perceptual consciousness to the probabilistic representations posited by the models that challenge conceptions of cognitive access as capacity-limited.

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion present a serious challenge for this view. First, I submit that austere-relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere-relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind-independent objects. Third, I develop a representationalist model of (...) IOMs. The proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity. (shrink)

Arguably one of the most fundamental phase shifts that occurred in the intellectual history of Western culture involved the ontological reduction of secondary qualities to primary qualities. To say the least, this reduction worked to undermine the foundations undergirding Aristotelian thought in support of a scientific view of the world based strictly on an examination of the real—primary— qualities of things. In this essay, I identify the so-called “Causal Argument” for a reductive view of secondary qualities and seek to deflect (...) this challenge by deriving some plausible consequences that support a non-reductive view of secondary qualities from an Aristotelian view (via the philosophical commentary of Thomas Aquinas). Specifically, my argument has two facets. First, I show that Aristotle’s view both implies recognition of the extramental existence of secondary qualities and is a prima facia natural view to take regarding the ontology of secondary qualities. Second, I show that the Causal Argument, which is thought to undermine a natural view of secondary qualities as real things, loses its bite when one examines perception in light the ontological relationship among the categories of quality, quantity and substance.

Weisberg introduces a phenomenon he terms perceptual undermining. He argues that it poses a problem for Jeffrey conditionalization, and Bayesian epistemology in general. This is Weisberg’s paradox. Weisberg argues that perceptual undermining also poses a problem for ranking theory and for Dempster-Shafer theory. In this note I argue that perceptual undermining does not pose a problem for any of these theories: for true conditionalizers Weisberg’s paradox is a false alarm.

In the current philosophy of perception, a debate about whether concepts permeate perceptual states in constituting the perceptual object or not has been widely discussed. Analytic philosophers and phenomenologists participate in this debate likewise, but it is also a debate in Kantian scholarship since the conceptualists’ thesis goes back to Kant’s Criticism and neo-Kantians already discussing such theory against any philosophy of immediate experience long before Wilfrid Sellars had started his attack against the so-called myth of the given. (...) In light of this historical panorama, the article reconstructs Ernst Cassirer’s views on perception in order to systematically reject both Conceptualism and Non-Conceptualism. It can be shown that both positions are uncritical stances which make claims to either the absoluteness of language or perception and that much-discussed arguments such as the fineness of grain argument rely on a category mistake. The proposed solution is a view that upholds the criticism against the myth of the given, but replaces the idea of a conceptual mediation of perceptual experience with a symbolic mediation. As a consequence, perception must perform a paradoxical feat and has thus to be elastic. (shrink)

Recent debates between representational and relational theories of perceptual experience sometimes fail to clarify in what respect the two views differ. In this essay, I explain that the relational view rejects two related claims endorsed by most representationalists: the claim that perceptual experiences can be erroneous, and the claim that having the same representational content is what explains the indiscriminability of veridical perceptions and phenomenally matching illusions or hallucinations. I then show how the relational view can claim that (...) errors associated with perception should be explained in terms of false judgments, and develop a theory of illusions based on the idea that appearances are properties of objects in the surrounding environment. I provide an account of why appearances are sometimes misleading, and conclude by showing how the availability of this view undermines one of the most common ways of motivating representationalist theories of perception.

Recently, it has been objected that naïve realism is inconsistent with an empirically well-supported claim that mental states of the same fundamental kind as ordinary conscious seeing can occur unconsciously (SFK). The main aim of this paper is to establish the following conditional claim: if SFK turns out to be true, the naïve realist can and should accommodate it into her theory. Regarding the antecedent of this conditional, I suggest that empirical evidence renders SFK plausible but not obvious. For it (...) is possible that what is currently advocated as unconscious perception of the stimulus is in fact momentaneous perceptual awareness (or residual perceptual awareness) of the stimulus making the subject prone to judge in some way rather than another, or to act in some way rather than another. As to the apodosis, I show that neither the core of naïve realism nor any of its main motivations is undermined if SFK is assumed. On the contrary, certain incentives for endorsing naïve realism become more tempting on this assumption. Since the main motivations for naïve realism retain force under SFK, intentionalism is neither compulsory nor the best available explanation of unconscious perception. (shrink)

Our emotional states affect how we perceive the world. If I am stressed, annoyed, or irritated, I might experience the sound of children laughing and screaming as they play around the house in a negative manner — it is unpleasant, loud, piercing, and so on. Yet, if I’m in a relaxed, happy, loving mood, the very same sounds might be experienced as pleasant, playful, warm, and so on. The sounds being made by the children are the same in both cases, (...) but how they are experienced differs. The auditory experience is affected by the emotional state that I am in. I perceive the sounds differently depending on how I’m feeling. Although this might at first seem to be a trivial observation, it certainly is not. We take for granted that our perceptual experiences give rise to justified beliefs and knowledge. Thus, if my perceptual experience of an object can differ based on my emotional state, and I take my perceptual experience to justify my beliefs and even lead to knowledge, then we might have a problem. If emotions — which are not fixed and in large part uncontrolled — affect our ability to accurately perceive the world, then they may undermine the justified beliefs and knowledge gained on the basis of our perceptual experience of the world. My goal here is to explore this potential problem. -/- I consider how we might understand the effect that emotions have on the justification of our perceptual beliefs about the world, beliefs that we acquire from a variety of sensory modalities — audition, gustation olfaction, and so on. I take the problem to be associated with one of two forms of perceptual influence: penetration or multisensory integration. In any given perceptual moment there are multiple sensory modalities and mental states at play, each affecting the overall experience. Whether we understand the influence of emotion on perception as a form of non-perceptual penetration or a form of non-visual sensory perception of the inner body — interoception — the potential epistemological difficulties remain: how can we be said to acquire justified beliefs and knowledge on the basis of such influenced perceptual experience. As has been the norm, only the five exteroceptive senses of vision, audition, olfaction, taste and touch are typically discussed in the context of sensory perception. However, as I argue, there is strong reason to accept the claim that emotional experience is a form of interoception, and that interoception ought to be considered when discussing sensory perception. In this way, then, I propose that clarifying the role played by interoception in sense perception across modalities is necessary if we are to make progress on the epistemological problems at hand.

The relationship between perceptual experience and memory can seem to pose a chal- lenge for conceptualism, the thesis that perceptual experiences require the actualization of conceptual capacities. Since subjects can recall features of past experiences for which they lacked corresponding concepts at the time of the original experience, it would seem that a subject’s conceptual capacities do not impose a limit on what he or she can experience perceptually. But this conclusion ignores the fact that concepts can be (...) composed of other simpler concepts that a subject possessed earlier, and that de- monstrative capacities can explain how a subject can experience a particular feature of her environment, even when she lacks a fully general concept for that feature. Using these resources, conceptualism can explain the relation between perceptual experience and memory. Nevertheless, a puzzle remains for the defender of conceptualism. A cer- tain view about the relation between perceptual experience and mental imagery in epi- sodic memory – that imagery in recall matches the experience retained in it – can make it difficult to understand how conceptualism could be true. For if a subject’s conceptual capacities determine what the phenomenology of an experience (or memory of it) is like, then one would expect a perceptual experience and its recall in memory to differ in phenomenology if they involve different concepts. In this essay, I solve this puzzle for conceptualism by undermining the assumption that there is a match between im- agery in episodic memory and the phenomenal character of experience. (shrink)

The etiology of a perceptual belief can seemingly affect its epistemic status. There are cases in which perceptual beliefs seem to be unjustified because the perceptual experiences on which they are based are caused, in part, by wishful thinking, or irrational prior beliefs. It has been argued that this is problematic for many internalist views in the epistemology of perception, especially those which postulate immediate perceptual justification. Such views are unable to account for the impact of (...) an experience’s etiology on its justificational status, McGrath, Siegel, and Vahid ). Our understanding of what we have been told can also be affected by, for example, wishful thinking or irrational background beliefs. I argue that testimonial beliefs based on such states of understanding can thus be rendered unjustified. This is problematic not only for internalist immediate justification views of testimony, but also for some externalist views, such as the form of proper functionalism endorsed by Burge, and Graham. The testimonial version of the argument from etiology, unlike the perceptual variant, does not rest on the controversial hypothesis that perception is cognitively penetrable. Furthermore, there is a stronger case for the claim that testimonial justification can be undermined by etiological effects since, I argue, testimonial beliefs can be based on the background mental states which affect our understanding of what is said, and our states of understanding are rationally assessable.

Hili Razinsky, free downlad at link. ABSTRACT: Emotional perceptions are objectivist (objectivity-directed or cognitive) and conscious, both attributes suggesting they cannot be ambivalent. Yet perceptions, including emotional perceptions of value, allow for strictly objectivist ambivalence in which a person unitarily perceives the object in mutually undermining ways. Emotional perceptions became an explicandum of emotion for philosophers who are sensitive to the unique conscious character of emotion, impressed by the objectivist character of perceptions, and believe that the perceptual account (...) solves a worry about the possibility of a conflict between an emotion and a judgement. Back into the 1980s Greenspan has argued that emotional ambivalence is possible, her reasons implying that objectivist accounts of emotion are inconsistent with ambivalence. Tappolet has more recently replied that perceptual accounts allow for emotional ambivalence since the opposed values seen in ambivalence are good or bad in different senses. The present paper identifies strict objectivist ambivalence between judgements and between emotional perceptions by contrasting them with such ambivalence of separate values such as evoked by Tappolet.

It is often assumed that adaptation — a temporary change in sensitivity to a perceptual dimension following exposure to that dimension — is a litmus test for what is and is not a “primary visual attribute”. Thus, papers purporting to find evidence of number adaptation motivate a claim of great philosophical significance: That number is something that can be seen in much the way that canonical visual features, like color, contrast, size, and speed, can. Fifteen years after its reported (...) discovery, number adaptation’s existence seems to be nearly undisputed, with dozens of papers documenting support for the phenomenon. The aim of this paper is to offer a counterweight — to critically assess the evidence for and against number adaptation. After surveying the many reasons for thinking that number adaptation exists, we introduce several lesser-known reasons to be skeptical. We then advance an alternative account — the old news hypothesis — which can accommodate previously published findings while explaining various (otherwise unexplained) anomalies in the existing literature. Next, we describe the results of eight pre-registered experiments which pit our novel old news hypothesis against the received number adaptation hypothesis. Collectively, the results of these experiments undermine the number adaptation hypothesis on several fronts, whilst consistently supporting the old news hypothesis. More broadly our work raises questions about the status of adaptation itself as a means of discerning what is and is not a visual attribute. (shrink)

Phenomenal objectivism explains perceptual phenomenal character by reducing it to an awareness of mind-independent objects, properties, and relations. A challenge for this view is that there is a sense in which a distant tree looks smaller than a closer tree even when they are the same objective size (perceptual size variation). The dual content view is a popular objectivist account in which such experiences are explained by my objective spatial relation to the tree, in particular visual angle (perspectival (...) size). I describe a series of first-person experiments for investigating size experience. I use a ruler as a first-person method for operationalising perspectival size (Experiment 1). I use the corridor illusion (Experiment 2), outlining one’s head in the mirror (Experiment 3), and outlining the size of objects on glass (Experiment 4) to show a phenomenal difference in size for items in different depth contexts, despite being identical in visual angle. These finding demonstrate that visual angle cannot account for these spatial experiences. Psychological evidence provides further support for the thesis that subjects do not experience visual angle when depth information is present. Together this evidence supports the hypothesis that perceptual size variation cannot be accounted for by visual angle, hence undermining a plausible version of the dual content theory. This outcome, combined with problems raised by alternative objectivist accounts of size variation, provides support for a subjectivist account of size experience. (shrink)

It is one thing to hold that merely statistical evidence is _sometimes_ insufficient for rational belief, as in typical lottery and profiling cases. It is another thing to hold that merely statistical evidence is _always_ insufficient for rational belief. Indeed, there are cases where statistical evidence plainly does justify belief. This project develops a dispositional account of the normativity of statistical evidence, where the dispositions that ground justifying statistical evidence are connected to the goals (= proper function) of objects. There (...) are strong intuitive motivations for doing this. For we can turn almost any case of _non-justifying_ merely statistical evidence into a case of _justifying_ merely statistical evidence by adding information about the dispositions and goals of the objects involved. The resulting view not only helps us understand when and why merely statistical evidence is normatively significant, but it also helps us understand how statistical evidence relates to more standard forms of evidence (perceptual, testimonial). The emerging view also has surprising applications, as it imposes limitations on the epistemic value of fine-tuning arguments for theism as well as undermines a standard class of case-based arguments for moral encroachment.

In Languages of Art, Nelson Goodman presents a general theory of symbolic notation. However, I show that his theory could not adequately explain possible cases of natural language notational uses, and argue that this outcome undermines, not only Goodman's own theory, but any broadly type versus token based account of notational structure.Given this failure, an alternative representational theory is proposed, in which different visual or perceptual aspects of a given physical inscription each represent a different letter, word, or other (...) notational item. Such a view is strongly supported by the completely conventional relation between inscriptions and notation, as shown by encryption techniques etc. (shrink)

Cartesian skepticism has its roots in classical skepticism and is geared to undermine our confidence even in immediate perceptual statements as `I see things in front of me'. We investigate with some assumptions which have as consequence that Cartesian skepticism is avoided in some contexts. I assume that Gettier style difficulties are not engendered by immediate perceptual statements, and I invoke things in general to not make assumptions in the metaphysics of objects. As Gettier issues are side stepped (...) for such statements as mentioned we have that I know that I see things in front of me if, and only if it is true that I see things in front of me, I am justified in believing that I see things in front of me and I believe that I see things in front of me. We assume epistemological deontologism, so that I am justified in believing something iff I am permitted to believe it. We assume Kant’s Law so that ‘ought’ implies ‘can’. As a matter of fact it is impossible for me to not believe that I see things in front of me; it follows by Kant’s Law that it is not the case that it ought to be the case that I do not believe that I see things in front of me; so I am permitted to believe that I see things in front of me, thence by epistemic deontologism I am justified in believing that I see things in front of me. Even the skeptic may not reasonably deny that it is true that I see things in front of me, and the skeptic does also not deny that I believe that I see things in front of me. Given our assumption that Gettier style difficulties do not apply for immediate perceptual statements it follows that I know that I see things in front of me. Needless to say, but one may challenge some of the assumptions we made to reach an anti skeptical conclusion. One may also explore the viability of extending the approach we have put forth here, and it can be of interest to explore further consequences for epistemology in general. The deontological conception of epistemic justification, e.g. in the version according to which a person is justified in holding p just in the case she is in some sense, normatively permitted to believe that p, has come under attack. According to William Alston, the major defect of epistemic deontologism is that it presupposes doxastic voluntarism, i.e. the view that we have direct voluntary control over whether to believe something or not. But Alston thinks that we have no such direct voluntary control, or rather that we only quite rarely have such control. And given this alleged failure of the prevalence of voluntary control, Alston maintains that "it is futile to discuss whether I am permitted to believe that p at t or whether I would be irresponsible in choosing to believe that p at t.".

Thinking the Visual, Visualizing the Thought.A perceptual and Political Model of VisionMerleau-Ponty’s program of perceptivizing thought has depoliticizing effects that, though he does not recognize them, undermine his understanding of politics. These anti-political consequences, moreover, bring out the internal difficulties of his anti-intellectualist starting point. There are three areas in which Merleau-Ponty gave a thorough application, though with unequal success, of his perception-based model: the presentation of his own thought, in which his program of picturalization had a striking success; (...) the explanation of the historical process, in which his visualization model was only partly effective; and access to other people’s thought, in which his perceptivist views encountered an undeniable failure. Merleau-Ponty’s successive approaches to other people’s thought show, by two distinct paths, and beyond his own intentions, an unforeseen political defect. His perceptive model proves incompatible with his political ideas when it is applied in depth, and it thus breaks apart the cohesion of his thought. From a larger perspective, it disrupts reflective approaches to politics since it damages their conceptual bases. This article shows successively that Merleau-Ponty laid out a perceptive model of universal scope; that he applied it to several areas, including politics; that this model proves politically deficient when it serves to remove the autochthonous sources of sense; that these depoliticizing effects become more acute when Merleau-Ponty employs the perceptive model to elucidate other people’s thought; and that its frustration in this area not only devalues his political reflections, but also signals that the perceptive model simply prevents a “thinking of the political.”Pensare il visuale, visualizzare il pensiero.Un modello percettivo e politico della visioneIl programma di percettivizzazione del pensiero intrapreso da Merleau-Ponty comporta effetti spoliticizzanti che sconfessano nascostamente la sua comprensione della politica. Tali conseguenze antipolitiche mettono altresì in rilievo le difficoltà intrinseche alla sua posizione anti-intellettualista. Vi sono tre ambiti nei quali Merleau-Ponty, con diverso successo, ha applicato il suo modello percettivo : la presentazione del suo stesso pensiero, nella quale questo programma di pittoricizzazione incontra un successo trionfale; la chiarificazione del processo storico, dove tale modello “visualeˮ non è efficace che in parte; infine l’accesso al pensiero di altri autori, terreno sul quale questa prospettiva percettivista subisce uno scacco innegabile. Molti tentativi merleaupontiani di approcciare il pensiero di altri autori attestano in vario modo un imprevisto deficit politico. Il modello percettivo di Merleau-Ponty si rivela in altri termini incompatibile con le sue idee politiche, nel momento in cui viene applicato in profondità, e in ultima analisi mette a dura prova la coerenza del suo pensiero. In una prospettiva più ampia, esso ostacola un approccio riflessivo alla politica poiché ne degrada le stesse basi concettuali. Il nostro articolo mostra quindi che Merleau-Ponty ha articolato un modello percettivo di portata universale; che l’ha applicato a svariati ambiti d’indagine, tra cui la politica; che quel modello si rivela deficitario quando viene utilizzato per attingere a specifiche fonti di senso; che tali effetti spoliticizzanti si acuiscono nel momento in cui Merleau-Ponty adotta il modello percettivo per illuminare il pensiero di altri autori; che, per concludere, la sua incongruenza con questo peculiare ambito di riflessione non solo impoverisce le sue riflessioni politiche, ma attesta che in linea generale il modello percettivo sbarra la strada a un qualsiasi «pensiero del politico».

Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of (...) hallucination and argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.

This paper offers a critical interpretation and evaluation of Wilfrid Sellars’s treatment of skepticism about empirical justification. It defends three central claims. First, against the suggestion that Sellars’s work simply bypasses traditional skeptical problems, I make the novel interpretive claim that Sellars not only addresses skepticism about empirical justification, but offers two independent (albeit sketchy) arguments against it: a transcendental argument that the likely truth of our perceptual beliefs is a necessary condition of the possibility of empirical content, and (...) a pragmatic argument that we’re warranted in accepting their likely truth in virtue of our aim of being effective agents. To the extent these have previously been distinctly formulated by commentators, the transcendental argument has been regarded as forceful, while the pragmatic argument has been dismissed as non-responsive. My second and third claims challenge this understanding. I argue, second, that examination of the literature relating to transcendental arguments from semantic externalism like Sellars’s (especially concerning the McKinsey paradox) suggests that such arguments are unpromising, while, third, a modified version of his pragmatic argument represents a powerful skeptical solution to skepticism about empirical justification, one that answers the worry that such skepticism would undermine the rationality of all our practical commitments.

It is often claimed that fear has an important epistemological function in making us aware of danger. Reactive theories challenge this view. According to them, fear is a response to real or apparent danger. In other words, real or apparent danger is the reason for which we experience fear. Thus, fear depends on awareness of danger instead of making us aware of danger. Proponents of the reactive theory have appealed to phenomenological and, most prominently, linguistic observations to support their views. (...) In particular, they argue that how we talk about the objects of fear supports the view that fear is a response (rather than a perception), and that how we talk about reasons for fear supports the view that reasons for fear are necessarily evaluative (about danger). Building on systematic linguistic observations in the form of corpus analyses and survey data, we argue that how we talk about the objects of fear and how we talk about reasons for fear do not support the reactive theory. Indeed, these linguistic considerations undermine the reactive theory. Most importantly, they suggest that there are non-evaluative reasons for fear. This is good news for rival theories, like perceptual theories, which hold that emotions have epistemic value in contributing to knowledge of evaluative properties such as danger. (shrink)

In this Introduction we introduce the central themes of the Evaluative Perception volume. After identifying historical and recent contemporary work on this topic, we discuss some central questions under three headings: (1) Questions about the Existence and Nature of Evaluative Perception: Are there perceptual experiences of values? If so, what is their nature? Are experiences of values sui generis? Are values necessary for certain kinds of experience? (2) Questions about the Epistemology of Evaluative Perception: Can evaluative experiences ever justify (...) evaluative judgments? Are experiences of values necessary for certain kinds of justified evaluative judgments? (3) Questions about Value Theory and Evaluative Perception: Is the existence of evaluative experience supported or undermined by particular views in value theory? Are particular views in value theory supported or undermined by the existence of value experience? (shrink)

Various prominent theories of pain assume that it is pain’s biological function to inform organisms about damage to their bodies. I argue that this is a mistake. First, there is no biological evidence to support the notion that pain was originally selected for its informative capacities, nor that it currently contributes to the fitness of organisms in this specific capacity. Second, neurological evidence indicates that modulating mechanisms in the nociceptive system systematically prevent pain from serving a primarily informative role. These (...) considerations threaten to undermine standard perceptual and representational accounts of pain. (shrink)

While there seems to be much evidence that perceptual states can occur without being conscious, some theorists recently express scepticism about unconscious perception. We explore here two kinds of such scepticism: Megan Peters and Hakwan Lau's experimental work regarding the well-known problem of the criterion -- which seems to show that many purported instances of unconscious perception go unreported but are weakly conscious -- and Ian Phillips' theoretical consideration, which he calls the 'problem of attribution' -- the worry that (...) many purported examples of unconscious perception are not perceptual, but rather merely informational and subpersonal. We argue that these concerns do not undermine the evidence for unconscious perception and that this sceptical approach results in a dilemma for the sceptic, who must either deny that there is unconscious mentality generally or explain why perceptual states are unique in the mind such that they cannot occur unconsciously. Both options, we argue, are problematic. (shrink)

Defeat cases are often taken to show that even the most securely-based judgment can be rationally undermined by misleading evidence. Starting with some best-case scenario for perceptual knowledge, for example, it is possible to undermine the subject’s confidence in her sensory faculties until it becomes unreasonable for her to persist in her belief. Some have taken such cases to indicate that any basis for knowledge is rationally defeasible; others have argued that there can be unreasonable knowledge. I argue that (...) defeat cases really involve not an exposure of weakness in the basis of a judgment, but a shift in that basis. For example, when threatening doubts are raised about whether conditions are favorable for perception, one shifts from a basis of unreflective perceptual judgment to a basis of conscious inference. In these cases, the basis of one’s knowledge is lost, rather than rationally undermined. This approach to defeat clears the path for a new way to defend infallibilism in epistemology, and a new understanding of what can count as the basis of any instance of knowledge. (shrink)

One central argument in favor of perceptual accounts of emotions concerns recalcitrant emotions: emotions that persist in the face of repudiating judgments. For, it is argued, to understand how the conflict between recalcitrant emotions and judgment falls short of incoherence in judgment, we need to understand recalcitrant emotions to be something like perceptual illusions of value, so that in normal, non-recalcitrant cases emotions are non-illusory perceptions of value. I argue that these arguments fail and that a closer examination (...) of recalcitrant emotions reveals important disanalogies with perception that undermine the perceptual model of emotions.

Perception solves computationally demanding problems at lightning fast speed. It recovers sophisticated representations of the world from degraded inputs, often in a matter of milliseconds. Any theory of perception must be able to explain how this is possible; in other words, it must be able to explain perception's computational tractability. One of the few attempts to move toward such an explanation has been the information encapsulation hypothesis, which posits that perception can be fast because it keeps computational costs low by (...) forgoing access to information stored in cognition. I argue that we have no compelling reason to believe that encapsulation explains (or even contributes to an explanation of) perceptual tractability, and much reason to doubt it. This is because there exist much deeper computational challenges for perception than information access, and these threaten to make the costs of access irrelevant. If this is right, it undermines a core computational motivation for encapsulation and sends us back to the drawing board for explanations of perceptual tractability. (shrink)

This paper defends the idea that there must be some joints in reality, some correct way to classify or categorize it. This may seem obvious, but we will see that there are at least three conventionalist arguments against this idea, as well as philosophers who have found them convincing. The thrust of these arguments is that the manner in which we structure, divide or carve up the world is not grounded in any natural, genuine boundaries in the world. Ultimately they (...) are supposed to pose a serious threat to realism. The first argument that will be examined concerns the claim that there are no natural boundaries in reality, the second one focuses on the basis of our classificatory schemes, which the conventionalist claims to be merely psychological, and the third considers the significance of our particular features in carving up the world, such as physical size and perceptual capabilities. The aim of this paper is to demonstrate that none of these objections succeed in undermining the existence of genuine joints in reality. (shrink)

Cognitive Penetration holds that cognitive states and processes, specifically propositional attitudes (e.g., beliefs), sometimes directly impact features of perceptual experiences (e.g., the coloring of an object). In contrast, more traditional views hold that propositional attitudes do not directly impact perceptual experiences, but rather are only involved in interpreting or judging these experiences. Understandably, Cognitive Penetration is controversial and has been criticized on both theoretical and empirical grounds. I focus on defending it from the latter kind of objection and (...) in doing so, highlight important features of Cognitive Penetration mechanisms and effects. I first sketch promising criteria for Cognitive Penetration and then address widespread Replication and Demonstration worries about purported instances of it. Next, I present one of the most compelling Cognitive Penetration studies and address specific objections against it and others. I demonstrate that each of these objections misunderstands important features of either Cognitive Penetration mechanisms or the specific studies to which they are applied. Ultimately, I conclude that multiple key studies are not undermined by these objections and con- tinue to provide support for Cognitive Penetration. Correcting these misunderstandings bolsters empirical support for Cognitive Penetration and contributes to a better understand- ing of the mechanisms involved in perceptual processing. (shrink)

Brain activity determines which relations between objects in the environment are perceived as differences and similarities in colour, smell, sound, etc. According to selectionism, brain activity does not create those relations; it only selects which of them are perceptually available to the subject on a given occasion. In effect, selectionism entails that perceptual experience is diaphanous, i.e. that sameness and difference in the phenomenal character of experience is exhausted by sameness and difference in the perceived items. It has been (...) argued that diaphaneity is undermined by phenomenological considerations and empirical evidence. This paper considers five prominent arguments of this sort and shows that none of them succeeds. (shrink)

ABSTRACT: The Reflexive Theory of Perception (RTP) claims that perception of an object or property X by an organism Z consists in Z being caused by X to acquire some disposition D toward X itself. This broadly behavioral perceptual theory explains perceptual intentionality and correct versus incorrect, plus successful versus unsuccessful, perception in a plausible evolutionary framework. The theory also undermines cognitive and perceptual modularity assumptions, including informational or purely epistemic views of perception in that, according to (...) the RTP, any X-caused and X-directed dispositions are genuinely perceptual—including affective, attitudinal, and immediately activated purely action-directed behavioral dispositions. Thus the RTP has the potential to provide the foundations for a broadly behavioral counter-revolution in cognitive science. (shrink)

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..

The project of my dissertation was to advance the metaphysical debate about temporal passage, by relating it to debates about the perceptual experience of time and change. It seems true that we experience temporal passage, even if there is disagreement whether time actually passes, or what temporal passage consists in. This appears to give the defender of dynamic time an advantage in accounting for our experience. I challenge this by arguing that no major account of temporal perception can accommodate (...) experiences of temporal passage such that we could infer passage from them. This shows that static theories of time are at no disadvantage in accounting for the phenomenology of temporality. The conclusion has far reaching consequences: for instance, an important motivation for holding an A-theory of time is precisely the psychological intuition that we experience temporal passage. By undermining that intuition, I undermine the motivation for holding an A-theory. (shrink)

Contemporary scientific and philosophical literature on perception often focuses on the relationship between perception and action, emphasizing the ways in which perception can be understood as geared towards action or ‘action-oriented’. In this paper I provide a framework within which to classify approaches to action-oriented perception, and I highlight important differences between the distinct approaches. I show how talk of perception as action-oriented can be applied to the evolutionary history of perception, neural or psychological perceptual mechanisms, the semantic content (...) or phenomenal character of perceptual states, or to the metaphysical nature of perception. I argue that there are no straightforward inferences from one kind of action-oriented perception to another. Using this framework and its insights, I then explore the notion of action-oriented perceptual representation which plays a key role in some approaches to embodied cognitive science. I argue that the concept of action-oriented representation proposed by Clark and Wheeler is less straightforward than it might seem, because it seems to require both that the mechanisms of perceptual representation are action-oriented and that the content of these perceptual representations are action-oriented. Given that neither of these claims can be derived from the other, proponents of action-oriented representation owe us separate justification for each claim. I will argue that such justifications are not forthcoming in the literature, and that attempts to reconstruct them run into trouble: the sorts of arguments offered for the representational mechanisms being action-oriented seem to undermine the sorts of arguments offered for the representational content being action-oriented, and vice-versa.

This paper controverts the ability of intentionalism about perception to account for unique epistemic significance of phenomenal consciousness. More specifically, the intentionalist cannot explain the latter without denying two well-founded claims: the transparency of experience, and the possibility of unconscious perception. If they are true, intentionality of perception entails that phenomenal consciousness has no special epistemic role to play. Although some intentionalists are ready to bite this bullet, by doing so they effectively undermine one of the standard motivations of their (...) view, i.e. the claim that perceptual experiences justify beliefs. Consequently, whatever reason might there be to think that phenomenal consciousness has unique epistemic import, it is also a reason to reject intentionalism. I recommend replacing the latter with an unorthodox formulation of relationalism about perception. (shrink)

Joel Pust has recently challenged the Thomas Reid-inspired argument against the reliability of the a priori defended by Alvin Plantinga, Nicholas Wolterstorff, William Alston, and Michael Bergmann. The Reidian argument alleges that the Cartesian insistence on the primacy of a priori rationality and subjective sensory experience as the foundations of epistemic justification is unwarranted because the same kind of global skeptical scenario that Cartesians recognize as challenging the legitimacy of perceptual beliefs about the external world also undermine the reliability (...) of a priori rationality. In reply, Pust contends that some a priori propositions are beyond doubt and that fact can be used to support the overall reliability of reason. This paper challenges Pust’s argument. I argue that while Pust successfully undermines a radical skeptical view of reason, he does not refute a more modest skepticism. I conclude with some suggestions for Cartesian a priorists. (shrink)

This chapter introduces and motivates the Null View about standard causally matching hallucinations. The Null View holds that these hallucinations fail to present any objects or sensible qualities, despite being dead ringers for perceptions of ordinary objects and their qualities. Motivation for the Null View comes from a neglected observation about perception-based thought, namely that perception can permit perception-based thought about a sensible quality even while misleading a subject about that quality. The chapter's other contribution is defensive. Most reject the (...) Null View on phenomenological or epistemic grounds. These objections to the Null View are sharpened and then undermined. (shrink)

Perceptual experiences are not immediately responsive to reasons. You see a stick submerged in a glass of water as bent no matter how much you know about light refraction. Due to this isolation from reasons, perception is traditionally considered outside the scope of epistemic evaluability as justified or unjustified. Is perception really as independent from reasons as visual illusions make it out to be? I argue no, drawing on psychological evidence from perceptual learning. The flexibility of perceptual (...) learning is a way of responding to new epistemic reasons. The resulting perceptual experiences are epistemically evaluable as justified or unjustified. (shrink)

According to capacitism, to perceive is to employ personal-level, perceptual capacities. In a series of publications, Schellenberg (2016, 2018, 2019b, 2020) has argued that capacitism offers unified analyses of perceptual particularity, perceptual content, perceptual consciousness, perceptual evidence, and perceptual knowledge. “Capacities first” (2020: 715); appealing accounts of an impressive array of perceptual and epistemological phenomena will follow. We argue that, given the Schellenbergian way of individuating perceptual capacities which underpins the above analyses, (...) perceiving an object does not require employing a perceptual capacity which picks it out. Although each eye, used on its own, can suffice for perceiving objects in one’s environment, binocular vision allows one to see the same object(s) via both eyes, taking advantage of informational disparities registered by each eye. Yet in certain conditions it is possible to simultaneously see one object via the left eye and a distinct object via the right eye (at least when the inputs are sufficiently similar to prevent the onset of binocular rivalry). We argue that capacitism has trouble making sense of this. After surveying responses, we conclude that not all of the above phenomena can be unified under the capacitist framework. We then present a more nuanced, disjunctivist account of how capacities are individuated. While it may be illuminating to think of perceiving as the employment of perceptual capacities, this picture does not best favour a ‘common factor’ theory of perceptual content in the way existing presentations have envisaged.

Perceptual systems respond to proximal stimuli by forming mental representations of distal stimuli. A central goal for the philosophy of perception is to characterize the representations delivered by perceptual systems. It may be that all perceptual representations are in some way proprietarily perceptual and differ from the representational format of thought (Dretske 1981; Carey 2009; Burge 2010; Block ms.). Or it may instead be that perception and cognition always trade in the same code (Prinz 2002; Pylyshyn (...) 2003). This paper rejects both approaches in favor of perceptual pluralism, the thesis that perception delivers a multiplicity of representational formats, some proprietary and some shared with cognition. The argument for perceptual pluralism marshals a wide array of empirical evidence in favor of iconic (i.e., image-like, analog) representations in perception as well as discursive (i.e., language-like, digital) perceptual object representations.

This chapter presents the perceptual reality monitoring theory of consciousness (PRM). PRM is a higher-order theory of consciousness. It holds that consciousness involves monitoring the reliability of one’s own sensory signals. I explain how a perceptual reality monitoring mechanism computes the higher order representations that are crucial for consciousness. While PRM accounts for the difference between conscious and unconscious states, it does not explain, on its own, why experiences feel the way they do—the phenomenal character of experience. PRM (...) is compatible with multiple theories of phenomenal character. Here, I show how to combine it with ‘Mental Quality Space’ theory. I finish by presenting empirical evidence for PRM, as well as some of its predictions. (shrink)

Perceptual malleability and diversity can stem from perceptual learning, expertise, genetics, disease, or accident. Perceptual malleability and diversity force us to reject the claim that perceptual capacities, perceptual experience, and perceptual content are universal across subjects and times. And it casts doubt on the presumption of a universal human perceptual nature. However, it does not directly challenge perceptual objectivity, understood as the claim that one can perceive a world of things and features (...) that are independent from oneself and one's experiences and that could be perceived by other subjects.

The aim of this paper is to argue that the phenomenal similarity between perceiving and visualizing can be explained by the similarity between the structure of the content of these two different mental states. And this puts important constraints on how we should think about perceptual content and the content of mental imagery.

Some have defended a Fregean view of perceptual content. On this view, the constituents of perceptual contents are Fregean modes of presentation (MOPs). In this paper, I propose that perceptual MOPs are best understood in terms of object files. Object files are episodic representations that store perceptual information about objects. This information is updated when sensory conditions change. On the proposed view, when a subject perceptually represents some object a under two distinct MOPs, then the subject (...) initiates two object files that both refer to a. My defense of this view appeals to its satisfaction of four constraints that I argue theories of perceptual MOPs should satisfy. Furthermore, I show that some existent accounts of perceptual MOPs fail to satisfy them. The defended constraints also indicate what is unique about perceptual, as opposed to linguistic or cognitive, MOPs. (shrink)

Suppose you have recently gained a disposition for recognizing a high-level kind property, like the property of being a wren. Wrens might look different to you now. According to the Phenomenal Contrast Argument, such cases of perceptual learning show that the contents of perception can include high-level kind properties such as the property of being a wren. I detail an alternative explanation for the different look of the wren: a shift in one’s attentional pattern onto other low-level properties. Philosophers (...) have alluded to this alternative before, but I provide a comprehensive account of the view, show how my account significantly differs from past claims, and offer a novel argument for the view. Finally, I show that my account puts us in a position to provide a new objection to the Phenomenal Contrast Argument. (shrink)

Perception provides us with access to the external world, but that access is shaped by our own experiential histories. Through perceptual learning, we can enhance our capacities for perceptual discrimination, categorization, and attention to salient properties. We can also encode harmful biases and stereotypes. This article reviews interdisciplinary research on perceptual learning, with an emphasis on the implications for our rational and normative theorizing. Perceptual learning raises the possibility that our inquiries into topics such as epistemic (...) justification, aesthetic criticism, and moral knowledge should include not only an examination of cognition but also of perception.

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content (...) apply only to accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational. (shrink)
