This volume presents ten new essays on the nature of perceptual imagination and perceptual memory, framed by an introductory overview of these topics. How do perceptual imagination and memory resemble and differ from each other and from other kinds of sensory experience? And what role does each play in perception and in the acquisition of knowledge? These are the two central questions that the contributors seek to address.

Perception is said to have assertoric force: It inclines the perceiver to believe its content. In contrast, perceptual imagination is commonly taken to be non-assertoric: Imagining winning a piano contest does not incline the imaginer to believe they actually won. However, abundant evidence from clinical and experimental psychology shows that imagination influences attitudes and behavior in ways similar to perceptual experiences. To account for these phenomena, I propose that perceptual imaginings have implicit assertoric force and (...) put forth a theory—the Prima Facie View—as a unified explanation for the empirical findings reviewed. According to this view, mental images are treated as percepts in operations involving associative memory. Finally, I address alternative explanations that could account for the reviewed empirical evidence—such as a Spinozian model of belief formation or Gendler’s notion of alief—as well as potential objections to the Prima Facie View.

The present investigation concerns Reid’s explanation of how objects (be they real or nonexistent) are conceived. This paper shows that there is a deep-rooted tension in Reid’s understanding of conception: although the type of conception employed in perception is closely related to the one employed in imagination, three fundamental features distinguish perceptual conception (as the former will be referred to throughout this paper) from imaginative conception (as the latter will be called henceforth). These features would have been ascribed (...) by Reid himself to conception as involved in perception, but not to conception as involved in imagination. He should have recognized them as marking the former as a different kind from the latter, and he should not have hastily lumped perceptual and imaginative conceptions together. (shrink)

A commonly-discussed feature of perceptual experience is that it has ‘assertoric’ or ‘phenomenal’ force. We will start by discussing various descriptions of the assertoricity of perceptual experience. We will then adopt a minimal characterization of assertoricity: a perceptual experience has assertoric force just in case it inclines the perceiver to believe its content. Adducing cases that show that visual experience is not always assertoric, we will argue that what renders these visual experiences non-assertoric is that they are (...) penetrated by belief-like imaginings. Lastly, we will explain why it is that when belief-like imaginings—as opposed to beliefs (and other cognitive states)—penetrate visual experience, they render visual experiences non-assertoric.

This article offers a reply to commentaries from Amy Kind, Casey O’Callaghan, and Wayne Wu. It features a defense and further analysis of perceptual malleability, as defended in Thinking and Perceiving. In turn, it considers the consequences of malleability for attention and the cognitive penetrability of perception, imagination and perceptual skills, and perceptual content and objectivity.

The point of this paper is to reveal a dogma in the ordinary conception of sensory imagination, and to suggest another way forward. The dogma springs from two main sources: a too close comparison of mental imagery to perceptual experience, and a too strong division between mental imagery and the traditional propositional attitudes (such as belief and desire). The result is an unworkable conception of the correctness conditions of sensory imaginings—one lacking any link between the conditions under which (...) an imagining aids human action and inference and the conditions under which it is veridical. The proposed solution is, first, to posit a variety of imaginative attitudes—akin to the traditional propositional attitudes—which have different associated correctness (or satisfaction) conditions. The second part of the solution is to allow for imaginings with “hybrid” contents, in the sense that both mental images and representations with language-like constituent structure contribute to the content of imaginings.

Imaginative representations are crucial to the generation of action--both pretense and plain action. But well-known theories of imagination on offer in the literature [1] fail to describe how perceptually-formatted imaginings (mental images) and motor imaginings function in the generation of action and [2] fail to recognize the important fact that spatially rich imagining can be integrated into one's perceptual manifold. In this paper, I present a theory of imagining that shows how spatially rich imagining functions in the generation (...) of action. I also describe the imaginative structures behind two under-explored forms of action: semi-pretense and pretense layering. In addition, I suggest that my theory of imagining meshes better than the competitors with current work in cognitive and affective neuroscience. (shrink)

It is often held that in imagining experiences we exploit a special imagistic way of representing mentality—one that enables us to think about mental states in terms of what it is like to have them. According to some, when this way of thinking about the mind is paired with more objective means, an explanatory gap between the phenomenal and physical features of mental states arises. This paper advances a view along those lines, but with a twist. What many take for (...) a special imagistic way of thinking about experiences is instead a special way of misconstruing them. It is this tendency to misrepresent experiences through the use of imagery that gives rise to the appearance of an explanatory gap. The pervasiveness and tenacity of this misrepresentational reflex can be traced to its roots in a particular heuristic for monitoring and remembering the mental states of others. The arguments together amount to a new path for defending the transparency of perceptual experience. (shrink)

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to (...) be favoured over the perceptual confidence view. (shrink)

Imagination seems to play an epistemic role in philosophical and scientific thought experiments, mindreading, and ordinary practical deliberations insofar as it generates new knowledge of contingent facts about the world. However, it also seems that imagination is limited to creative generation of ideas. Sometimes we imagine fanciful ideas that depart freely from reality. The conjunction of these claims is what I call the puzzle of knowledge through imagination. This chapter aims to resolve this puzzle. I argue that (...) imagination has an epistemic role to play, but it is limited to the context of discovery. Imagination generates ideas, but other cognitive capacities must be employed to evaluate these ideas in order for them to count as knowledge. Consideration of the Simulation Theory's so-called "threat of collapse” provides further evidence that imagination does not, on its own, yield new knowledge of contingent facts, and it suggests a way to supplement imagination in order to get such knowledge.

Look at a red apple. Now close your eyes and visualize this apple. Your perceptual state and your imagery of the apple are very similar in some respects. They are also different in some respects. The aim of this paper is to address three questions about the relation between perception and imagination: -/- (a) How similar are perception and imagination and what explains this similarity? (b) How different are perception and imagination and what explains this difference? (...) (c) How do perception and imagination interact? (shrink)

As an important view in the epistemology of perception, dogmatism proposes that for any experience, if it has a distinctive kind of phenomenal character, then it thereby provides us with immediate justification for beliefs about the external world. This paper rejects dogmatism by looking into the epistemology of imagining. In particular, this paper first appeals to some empirical studies on perceptual experiences and imaginings to show that it is possible for imaginings to have the distinctive phenomenal character dogmatists have (...) in mind. Then this paper argues that some of these imaginings fail to provide us with immediate justification for beliefs about the external world at least partly due to their inappropriate etiology. Such imaginings constitute counterexamples to dogmatism. (shrink)

The method of phenomenal contrast (in perception) invokes the phenomenal character of perceptual experience as a means to discover its contents. The method implicitly takes for granted that ‘what it is like’ to have a perceptual experience e is the same as ‘what it is like’ to imagine or recall it; accordingly, in its various proposed implementations, the method treats imaginations and/or recollections as interchangeable with real experiences. The method thus always contrasts a pair of experiences, at least (...) one of which is imagined or remembered rather than occurrent. Surveying all eighteen forms of implementing the method, I argue that in all of the proposed pairings, the substitution of imagination or recollection for perceptual experience in the method, is either inconceivable or impermissible. I identify four reasons why I think imagination cannot be substituted for real experience, and three reasons why recollection cannot be substituted for real experience. If my argument works, there is no form of implementing the method that is useful for discovering the contents of experience, and thus the method is not a well‐functioning tool to study the contents of perception.

When we see an object, we also represent those parts of it that are not visible. The question is how we represent them: this is the problem of amodal perception. I will consider three possible accounts: (a) we see them, (b) we have non-perceptual beliefs about them and (c) we have immediate perceptual access to them, and point out that all of these views face both empirical and conceptual objections. I suggest and defend a fourth account, according to (...) which we represent the occluded parts of perceived objects by means of mental imagery. This conclusion could be thought of as a (weak) version of the Strawsonian dictum, according to which “imagination is a necessary ingredient of perception itself”. (shrink)

Kendall Walton explains pictures in terms of games of perceptual make-believe. Pictures or depictions are props that draw us to participate in games of make-believe where we imagine seeing what a picture depicts. Walton proposes that one imagines of one’s perceptual experience of the coloured canvas that it is a different perceptual experience. The issue is whether perception and imagination can combine the way Walton suggests. Can one imagine a perception to be different? To get a (...) clearer understanding of the unified perceptual-imaginative experience Walton posits, the paper turns to competing theories that explain perceptual experience in terms of contents, relations to objects, or both contents and relations. Walton appeals to theories of perceptual content and cognitive penetration. But it is also important to examine whether his view fits with recent theories that explain perception only in terms of relations or in terms of both contents and relations. The paper argues that Walton’s view is compatible with content theories of perception and can be defended from some objection once we look at the detail these theories offer. Walton’s view is not compatible with pure relational theories of perception but it can be explained by hybrid content-relational theories of perception that posit de re senses. (shrink)

In this article , I first engage in some conceptual clarification of what the words "imagine," "imagining," and "imagination" can mean. Each has a constructive sense, an attitudinal sense, and an imagistic sense. Keeping the senses straight in the course of cognitive theorizing is important for both psychology and philosophy. I then discuss the roles that perceptual memories, beliefs, and genre truth attitudes play in constructive imagination, or the capacity to generate novel representations that go well beyond (...) what's prompted by one's immediate environment.

Imagine I hold up a Granny Smith apple for all to see. You would thereby gain justified beliefs that it was green, that it was apple, and that it is a Granny Smith apple. Under classical foundationalism, such simple visual beliefs are mediately justified on the basis of reasons concerning your experience. Under dogmatism, some or all of these beliefs are justified immediately by your experience and not by reasons you possess. This paper argues for what I call the looks (...) view of the justification of simple visual beliefs. According to the looks view, such beliefs are mediately justified on the basis of reasons concerning how the relevant things look. Unlike under classical foundationalism, under the looks view as I develop it, these reasons are public. They are public with respect to both their content and possession: with respect to content, they are not about ourselves and our experiences, and with respect to their possession, many people can have the very same looks-related reasons.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive (...) is to represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

This chapter argues that epistemic uses of the imagination are a sui generis form of reasoning. The argument proceeds in two steps. First, there are imaginings which instantiate the epistemic structure of reasoning. Second, reasoning with imagination is not reducible to reasoning with doxastic states. Thus, the epistemic role of the imagination is that it is a distinctive way of reasoning out what follows from our prior evidence. This view has a number of important implications for the (...) epistemology of the imagination. For one thing, it clarifies the epistemic role of widely invoked “constraints” on the imagination. For another, it highlights important and underappreciated disanalogies between how perceptual experiences and imaginings justify beliefs. Ultimately, the view that we can reason with imagination offers an illuminating and theoretically fruitful framework through which to understand the epistemic structure of the imagination. (shrink)

What is the relation between affective states, such as emotions and pleasure, and imagining? Do the latter cause the former, just as perceptual states do? Or are the former merely imagined, along with suitable objects? I consider this issue against the backdrop of Sartre’s theory of imagination, and drawing on his highly illuminating discussion of it. I suggest that, while it is commonly assumed that imaginative states cause affective responses much as do perceptions, the alternatives merit more careful (...) consideration than they are usually given. (shrink)

Traditionally, philosophers have appealed to the phenomenological similarity between visual experience and visual imagery to support the hypothesis that there is significant overlap between the perceptual and imaginative domains. The current evidence, however, is inconclusive: while evidence from transcranial brain stimulation seems to support this conclusion, neurophysiological evidence from brain lesion studies (e.g., from patients with brain lesions resulting in a loss of mental imagery but not a corresponding loss of perception and vice versa) indicates that there are functional (...) and anatomical dissociations between mental imagery and perception. Assuming that the mental imagery and perception do not overlap, at least, to the extent traditionally assumed, then the question arises as to what exactly mental imagery is and whether it parallels perception by proceeding via several functionally distinct mechanisms. In this review, we argue that even though there may not be a shared mechanism underlying vision for perception and conscious imagery, there is an overlap between the mechanisms underlying vision for action and unconscious visual imagery. On the basis of these findings, we propose a modification of Kosslyn’s model of imagery that accommodates unconscious imagination and explore possible explanations of the quasi-pictorial phenomenology of conscious visual imagery in light of the fact that its underlying neural substrates and mechanisms typically are distinct from those of visual experience.

Aesthetic non-cognitivists deny that aesthetic statements express genuinely aesthetic beliefs and instead hold that they work primarily to express something non-cognitive, such as attitudes of approval or disapproval, or desire. Non-cognitivists deny that aesthetic statements express aesthetic beliefs because they deny that there are aesthetic features in the world for aesthetic beliefs to represent. Their assumption, shared by scientists and theorists of mind alike, was that language-users possess cognitive mechanisms with which to objectively grasp abstract rules fixed independently of human (...) responses, and that cognizers are thereby capable of grasping rules for the correct application of aesthetic concepts without relying on evaluation or enculturation. However, in this article I use Wittgenstein’s rule-following considerations to argue that psychological theories grounded upon this so-called objective model of rule-following fail to adequately account for concept acquisition and mastery. I argue that this is because linguistic enculturation, and the perceptual learning that’s often involved, influences and enables the mastery of aesthetic concepts. I argue that part of what’s involved in speaking aesthetically is to belong to a cultural practice of making sense of things aesthetically, and that it’s within a socio-linguistic community, and that community’s practices, that such aesthetic sense can be made intelligible.

In this article, I defend the view that we can acquire factual knowledge – that is, contingent propositional knowledge about certain (perceivable) aspects of reality – on the basis of imaginative experience. More specifically, I argue that, under suitable circumstances, imaginative experiences can rationally determine the propositional content of knowledge-constituting beliefs – though not their attitude of belief – in roughly the same way as perceptual experiences do in the case of perceptual knowledge. I also highlight some philosophical (...) consequences of this conclusion, especially for the issue of whether imagination can help us to learn something from fictions. (shrink)

We tend to think that perceptual experiences tell us about what the external world is like without being influenced by our own mind. But recent psychological and philosophical research indicates that this might not be true. Our beliefs, expectations, knowledge, and other personal-level mental states might influence what we experience. This kind of psychological phenomena is now called “cognitive penetration.” The research of cognitive penetration not only has important consequences for psychology and the philosophy of mind, but also has (...) interesting epistemological implications. According to the Downgrade Thesis, some cognitively penetrated perceptual experiences give their subjects less justification for believing their penetrated contents than perceptual experiences that are unpenetrated to represent those contents would usually give. In this paper, I propose an innovative argument for the Downgrade Thesis. First, I develop a positive account of how some cognitive penetration works, according to which cognitive states influence perceptual experiences by triggering some imaginings. Second, I argue that imaginings do not give their subjects justification for believing their contents. I apply this epistemology of imagining to cognitive penetration, and argue that because of the role that imaginings play, some cognitively penetrated experiences also give their subjects less justification for believing their penetrated contents.

Abstract: In The Imaginary Jean-Paul Sartre makes what will strike many as an implausibly strong claim, namely that perception and imagination are incompatible kinds of experience - I call this the exclusion claim. This paper offers a reconstruction of Sartre’s exclusion claim. First, it frames the claim in terms of cross-modal attention distribution, such that it is not possible to simultaneously attend to what one is imagining and what one is perceiving. However, this leaves it open that a subject (...) can simultaneously imagine and perceive on the condition that either the perceived or imagined objects are not attended to. While this is a philosophically plausible position it fails to do justice to Sartre’s intended position, which suggests a more radical exclusion between perception and imagination. In light of this section 3 develops a supplementary argument to remove one of the possible configurations of attention that the ban on divided attention leaves in place by arguing that the objects of imagining must be attended to, which follows from Sartre’s characterisation of imagination as spontaneous. The resulting exclusion is as follows: attentive perception excludes imagination (and vice versa), given that the latter is necessarily attentive, but attentive imagination can co-occur with non-attentive or background perception (in this sense the exclusion is asymmetric in a way that Sartre fails to recognise). In concluding I detail how from this exclusion we get an important consequence – which Sartre wants the exclusion claim to have – namely that it rules out an imagination-based solution to the problem of perceptual presence.

How tight is the conceptual connection between imagination and perception? A number of philosophers, from the early moderns to present-day predictive processing theorists, tie the knot as tightly as they can, claiming that states of the imagination, i.e. mental imagery, are a proper subset of perceptual experience. This paper labels such a view ‘perceptualism’ about the imagination and supplies new arguments against it. The arguments are based on high-level perceptual content and, distinctly, cognitive penetration. The (...) paper also defuses a recent, influential argument for perceptualism based on the ‘discovery’ that visual perception and mental imagery share a significant neural substrate: circuitry in V1, the brain’s primary visual cortex. Current neuropsychology is shown to be equivocal at best on this matter. While experiments conducted on healthy, neurotypical subjects indicate substantial neural overlap, there is extensive clinical evidence of dissociations between imagery and perception in the brain, most notably in the case of aphantasia.

This book develops a theory of how the imagination functions, and how it evolved. The imagination is characterized as an embodied cognitive system. The system draws upon sensory-motor, visual, and linguistic capacities, but it is a flexible, developmental ability, typified by creative improvisation. The imagination is a voluntary simulation system that draws on perceptual, emotional, and conceptual elements, for the purpose of creating works that adaptively investigate external (environmental) and internal (psychological) resources. Beyond the adaptive useful (...) values of this system, imagination also possesses significant intrinsic value (e.g., in the joy of play, and states of wonder). The book argues that imagination is not a late arrival in the evolution of mind, but one of the earliest human abilities. (shrink)

Participants in the cognitive phenomenology debate have proceeded by (a) proposing a bifurcation of theoretical options into inflationary and non-inflationary theories, and then (b) providing arguments for/against one of these theories. I suggest that this method has failed to illuminate the commonalities and differences among conscious intentional states of different types, in the absence of a theory of the structure of these states. I propose such a theory. In perception, phenomenal-intentional properties combine with somatosensory properties to form P-I property clusters (...) that serve as phenomenal modes of presentations of particulars. In imagination, somatosensory properties are replaced with phenomenal-intentional properties whose intentional objects are somatosensory properties, thus resulting in imaginative facsimiles of perceptual P-I property clusters. Such structures can then be used as phenomenal prototypes that pick out individuals and kinds. Sets of such prototypes constitute a subject’s conception of individuals and kinds. Combined with a few additional elements, these imaginative P-I property clusters serve as the building-blocks of conscious cognitive states. Different ways of carving up theoretical space classify my theory either as inflationary or as non-inflationary. I conclude that the theory is anti-inflationary in letter but inflationary in spirit.

The highly enjoyable experiences associated with drinking good wines have been widely misunderstood. It is common to regard wine appreciation as an analytical or quasi-scientific kind of activity, in which wine experts carefully distinguish the precise sensory qualities of each wine, and then pass on their accumulated factual knowledge to less experienced wine enthusiasts. However, this model of wine appreciation is seriously defective. One good way to show its defects is to provide a better and more fundamental scientific account of (...) what is involved in wine appreciation. In order to do so, I outline a novel, evolutionarily based theory of perceptual consciousness that explains why there must be imaginative as well as analytical kinds of experiences of wines. In addition, imaginative wine experiences, unlike typical imaginative artistic experiences, may be shown to involve highly individualistic, improvisatory elements that help to give wine drinking a unique place among the recreational arts.

This chapter addresses the application of contemporary theories of the imagination—largely drawn from cognitive psychology—to our understanding of film. Topics include the role of the imagination in our learning what facts hold within a fictional film, including what characters’ motivations, beliefs, and feelings are; how our perceptual experience of a film explains our imaginative visualizing of its contents; how fictional scenarios in films generate certain affective and evaluative responses; and how such responses compare to those we have (...) toward analogous circumstances in real life.

This is the original, longer draft for my entry on Hume in the 'The Routledge Hand- book of Philosophy of Imagination', edited by Amy Kind and published by Routledge in 2016 (see the separate entry). — Please always cite the Routledge version, unless there are passages concerned that did not make it into the Handbook for reasons of length. — -/- This chapter overviews Hume’s thoughts on the nature and the role of imagining, with an almost exclusive focus on (...) the first book of his Treatise of Human Nature. Over the course of this text, Hume draws and discusses three important distinctions among our conscious mental episodes (or what he calls ‘perceptions’): (i) between impressions (including perceptual experiences) and ideas (including recollections, imaginings and occurrent beliefs); (ii) between ideas of the memory and ideas of the imagination; and (iii), among the ideas of the imagination, between ideas of the judgement (i.e. occurrent beliefs) and ideas of the fancy (i.e. imaginings). I discuss each distinction in turn, also in connection to contemporary views on imagining. In addition, I briefly consider Hume’s views on the imagination as a faculty aimed at the production of ideas, as well as on the role that imagining plays in the wider context of our mental lives, notably in the acquisition of modal knowledge and in the comprehension of, and resistance to, stories and opinions that we take to be false or fictional.

Sora from Open AI has shown exceptional performance, yet it faces scrutiny over whether its technological prowess equates to an authentic comprehension of reality. Critics contend that it lacks a foundational grasp of the world, a deficiency V-JEPA from Meta aims to amend with its joint embedding approach. This debate is vital for steering the future direction of Artificial General Intelligence(AGI). We enrich this debate by developing a theory of productive imagination that generates a coherent world model based on (...) Kantian philosophy. We identify three indispensable components in the coherent world model that enable genuine world understanding: latent representations of isolated objects, an a priori law of change across space and time, and Kantian categories. Our analysis reveals that Sora is limited because of its oversight of the a priori law of change and Kantian categories, flaws that are not rectifiable through scaling up the training. V-JEPA learns the context-dependent aspect of the a priori law of change. Yet it fails to fully comprehend Kantian categories and incorporate experience, leading us to conclude that neither system currently achieves a comprehensive world understanding. Nevertheless, each system has developed components essential to advancing an integrated AI productive imagination-understanding engine. Finally, we propose an innovative training framework for an AI productive imagination-understanding engine, centered around a joint embedding system designed to transform disordered perceptual input into a structured, coherent world model. Our philosophical analysis pinpoints critical challenges within contemporary video AI technologies and a pathway toward achieving an AI system capable of genuine world understanding, such that it can be applied for reasoning and planning in the future.

My topic in this paper will be Hume’s claim that we have no idea of a vacuum. I offer a novel interpretation of Hume’s account of our ideas of extension that makes it clear why those ideas cannot include any ideas of vacuums, and I distinguish my interpretation from prominent readings offered by other Hume scholars. An upshot of Hume’s account, I will argue, is his commitment to a remarkable and distinctly Humean view I call “perceptual relationism.” Perceptual (...) relationism is a fundamental characteristic of Hume’s “universe of the imagination,” and a manifestation of just how “loose and separate” the constituents of that inner universe are. Once we understand perceptual relationism and its entailments, we are in a better position to understand the rest of Hume’s sometimes puzzling remarks on space and the vacuum. (shrink)

I defend the thesis that most or all perceptual experiences are infused with imaginative contributions. While the idea is not new, it has few supporters. I begin by developing a framework for the underlying debate. Central to that framework is the claim that a perceptual experience is infused with imagination if and only if there are self-generated contributions to that experience that have ampliative effect on its phenomenal and directed elements. Self-generated ingredients to experience are produced by (...) the subject as opposed to being received from the world. Some form of stored content is an obvious starting point. Ampliative effects are aspects of perceptual experience that outstrip the content the senses get from the world. This conceptual framework is applied to three case studies: object-sameness and object-kind recognition (section 2), memory colour (section 3), and perceptual constancy and amodal completion (section 4). If the three cases and my overall analysis are accepted (a substantive if), then we have a forceful inductive argument for perception being infused with imagination. (shrink)

In his paper, The Transparency of Experience, M.G.F. Martin has put forward a well- known – though not always equally well understood – argument for the disjunctivist, and against the intentional, approach to perceptual experiences. In this article, I intend to do four things: (i) to present the details of Martin’s complex argument; (ii) to defend its soundness against orthodox intentionalism; (iii) to show how Martin’s argument speaks as much in favour of experiential intentionalism as it speaks in favour (...) of disjunctivism; and (iv) to argue that there is a related reason to prefer experiential intentionalism over Martin’s version of disjunctivism.

The thesis of cognitive penetrability, according to which cognitive states can affect perceptual experiences, remains the topic of intense debate among philosophers. A new candidate for a case of cognitive penetration is presented and defended. The candidate is based on studies involving suggestions that something is a certain way, which are usually given under hypnosis, rather than mere request to imagine that things are a certain way.

Balancing a hermeneutic of trust with a hermeneutic of suspicion, this article develops a phenomenological description of imagination that highlights its alethic ambiguity. Imagination is an act of disclosure, without which the world of fiction and pure possibility cannot be constituted. Imagination is also an act of self-indulgence and narcissism, the source of much concealment and untruth. It is not the one or the other, but both at the same time, essentially ambiguous because of its phenomenological constitution. (...) In this article, I will take some steps towards clarifying this essential ambiguity of the imagination by drawing on the insights of Husserl and Sartre. Beginning with Husserl’s parallel treatment of imagination and perception as intuitive, objectifying acts, I will argue, drawing on insights from Sartre, that there is an important discrepancy between them with respect to the role of desire. While the constitution of perceptual presence is inseparable from a desire for truth, the desire involved in the constitution of imaginary presence has an ambiguous character, both epistemic and magical. This duplicity of desire partly accounts for the ambiguity of imagination, which is all the more pronounced the more the imagination demands the full emotional involvement of the imagining subject.

This paper proposes a novel experimental approach that would help to determine whether perspectival shapes, such as the elliptical profile of a tilted plate or coin, are part of perceptual experience. If they are part of perceptual experience, then it should be possible to identify these shapes simply by attending appropriately to them. Otherwise, in order to identify perspectival shapes they must first be constructed in the visual imagination. We propose that these accounts of perspectival identification can (...) be tested by measuring the interference between visual and verbal working memory load, respectively, and the identification of perspectival shapes in the appearance of a 3D object.

Malebranche holds that visual experience represents the size of objects relative to the perceiver's body and does not represent objects as having intrinsic or nonrelational spatial magnitudes. I argue that Malebranche's case for this body-relative thesis is more sophisticated than other commentators—most notably, Atherton and Simmons —have presented it. Malebranche's central argument relies on the possibility of perceptual variation with respect to size. He uses two thought experiments to show that perceivers of different sizes—namely, miniature people, giants, and typical (...) human beings—can experience the very same objects as having radically different sizes. Malebranche argues that there is no principled reason to privilege one of these ways of experiencing size over the others and, more specifically, that all three kinds of perceivers experience size veridically. From the possibility of this kind of veridical perceptual variation, Malebranche infers that visual experience represents only body-relative size. (shrink)

The psychology and phenomenology of our knowledge of other minds is not well captured either by describing it simply as perception, nor by describing it simply as inference. A better description, I argue, is that our knowledge of other minds involves both through ‘perceptual co-presentation’, in which we experience objects as having aspects that are not revealed. This allows us to say that we perceive other minds, but perceive them as private, i.e. imperceptible, just as we routinely perceive aspects (...) of physical objects as unperceived. I discuss existing versions of this idea, particularly Joel Smith’s, on which it is taken to imply that our knowledge of other minds is, in these cases, perceptual and not inferential. Against this, I argue that perceptual co-presentation in general, and mind-perception in particular, yields knowledge that is simultaneously both perceptual and inferential. (shrink)

Human beings have the ability to ‘augment’ reality by superimposing mental imagery on the visually perceived scene. For example, when deciding how to arrange furniture in a new home, one might project the image of an armchair into an empty corner or the image of a painting onto a wall. The experience of noticing a constellation in the sky at night is also perceptual-imaginative amalgam: it involves both seeing the stars in the constellation and imagining the lines that connect (...) them at the same time. I here refer to such hybrid experiences – involving both a bottom-up, externally generated component and a top-down, internally generated component – as make-perceive (Briscoe 2008, 2011). My discussion in this paper has two parts. In the first part, I show that make-perceive enables human beings to solve certain problems and pursue certain projects more effectively than bottom-up perceiving or top-down visualization alone. To this end, the skillful use of projected mental imagery is surveyed in a variety of contexts, including action planning, the interpretation of static mechanical diagrams, and non-instrumental navigation. In the second part, I address the question of whether make-perceive may help to account for the “phenomenal presence” of occluded or otherwise hidden features of perceived objects. I argue that phenomenal presence is not well explained by the hypothesis that hidden features are represented using projected mental images. In defending this position, I point to important phenomenological and functional differences between the way hidden object features are represented respectively in mental imagery and amodal completion.

A common view about the phenomenology of episodic remembering has it that when we remember a perceptual experience, we can relive or re-experience many of its features, but not its characteristic presence. In this paper, we challenge this common view. We first say that presence in perception divides into temporal and locative presence, with locative having two sides, an objective and a subjective one. While we agree with the common view that temporal and objective locative presence cannot be relived (...) in remembering, we argue that subjective locative presence – the feeling of being immersed in a certain scene – can be so. Our argument for this claim starts by determining independently the underpinning mechanisms of subjective locative presence in quasi-perceptual imagination. These mechanisms are self-projection, imaginative pretence, and attentional focus. We then proceed to establish that they have been found to underpin conscious states of episodic remembering too. We conclude that episodic remembering can bring us to relive the subjective locative presence characteristic of a perceptual experience, and that the common view is mistaken. Our view – ‘mnemonic immersivism’ – has important consequences regarding the relationships between memory and imagination and the phenomenology of episodic remembering. (shrink)

Visual imagination (or visualization) is peculiar in being both free, in that what we imagine is up to us, and useful to a wide variety of practical reasoning tasks. How can we rely upon our visualizations in practical reasoning if what we imagine is subject to our whims? The key to answering this puzzle, I argue, is to provide an account of what constrains the sequence in which the representations featured in visualization unfold—an account that is consistent with its (...) freedom. Three different proposals are outlined, building on theories that link visualization to sensorimotor predictive mechanisms (e.g., efference copies, forward models ). Each sees visualization as a kind of reasoning, where its freedom consists in our ability to choose the topic of the reasoning. Of the three options, I argue that the approach many will find most attractive—that visualization is a kind of off-line perception, and is therefore in some sense misrepresentational—should be rejected. The two remaining proposals both conceive of visualization as a form of sensorimotor reasoning that is constitutive of one’s commitments concerning the way certain kinds of visuomotor scenarios unfold. According to the first, these commitments impinge on one’s web of belief from without, in the manner of normal perceptual experience; according to the second, these commitments just are one’s (occurrent) beliefs about such generalizations. I conclude that, despite being initially counterintuitive, the view of visualization as a kind of occurrent belief is the most promising. (shrink)

The nature and consequences of readers’ affective engagement with literature has, in recent years, captured the attention of experimental psychologists and philosophers alike. Psychological studies have focused principally on the causal mechanisms explaining our affective interactions with fictions, prescinding from questions concerning their rational justifiability. Transportation Theory, for instance, has sought to map out the mechanisms the reader tracks the narrative experientially, mirroring its descriptions through first-personal perceptual imaginings, affective and motor responses and even evaluative beliefs. Analytical philosophers, by (...) contrast, have largely focussed on the problems fiction poses for traditional theories of rationality (as in the ‘Paradox of Fiction), challenging fiction’s wider epistemic value. The result has been a theoretical impasse in which the power of fiction to affectively ‘transport’ a reader is at once often lauded (by psychologists) as a privileged route to interpersonal understanding, and condemned (by philosophers) as an abdication of the authority of reason. This chapter surveys some of the central claims on both sides, tracing the source of the debate to competing conceptions of rationality. (shrink)

ABSTRACT Cognitive penetrability refers to the possibility that perceptual experiences are influenced by our beliefs, expectations, emotions, or other personal-level mental states. In this paper, I focus on the epistemological implication of cognitive penetration, and examine how, exactly, aetiologies matter to the justificatory power of perceptual experiences. I examine a prominent theory, according to which some cognitively penetrated perceptual experiences are like conclusions of bad inferences. Whereas one version of this theory is psychologically implausible, the other version (...) has sceptical consequences. In the second half of the paper, I suggest an alternative theory, drawing on recent empirical research on imagining-perception interaction and the epistemology of imagining. (shrink)

Vision often dominates other perceptual modalities both at the level of experience and at the level of judgment. In the well-known McGurk effect, for example, one’s auditory experience is consistent with the visual stimuli but not the auditory stimuli, and naïve subjects’ judgments follow their experience. Structurally similar effects occur for other modalities (e.g. rubber hand illusions). Given the robustness of this visual dominance, one might not be surprised that visual imagery often dominates imagery in other modalities. One might (...) be surprised, however, that visual imagery often dominates perception in other modalities. This more controversial claim is motivated both by empirical data and by introspection. Some think of perception-perception visual dominance as epistemically good, holding that cases in which visual dominance misleads us (e.g. McGurk and rubber hand illusions) are cases in which the perceptual system resolves conflicts according to principles that are generally reliable. Here, we explore support for the more controversial claim that imagery-perception visual dominance is epistemically good. We suggest that, when the task is richly spatial, requiring for optimal performance the all-at-once identification of macro-spatial and allocentric properties (e.g. identifying the shape or location of a felt or heard object), the visual, whether perception or imagination, should dominate other modalities. Put another way, when identifying objects, one should go and look or, short of that, visually imagine candidate objects, and then follow the visual, even against conflicting perceptions from other modalities. For this broadly-typed category of of cognitive-perceptual task, vision does dominate and it should. (shrink)

In this paper I explicate the notion of “presence” [Gegenwart] as it pertains to intuition. Specifically, I examine two central problems for the position that an empirical intuition is an immediate relation to an existing particular in one’s environment. The first stems from Kant’s description of the faculty of imagination, while the second stems from Kant’s discussion of hallucination. I shall suggest that Kant’s writings indicate at least one possible means of reconciling our two problems with a conception of (...) “presence” such that perceptual and hallucinatory states might be understood as different kinds of intuition. This may not be sufficient to secure the relationalist’s claim that intuition is an immediate relation to an existing particular in one’s environment, but it does show that opposition to this claim will require further argument.

How does visual imagination differ from visual perceptual experience? And how should we describe experiences of visual imagery? Moreover how can people who have visual imagery convey what it is like to have it to those who have never had it – congenital aphantisics? This paper addresses these questions using examples of illusions and other perceptual phenomena to hone in on the answers.

Imagine your mirror‐inverted counterpart on Mirror Earth, a perfect mirror image of Earth. Would her experiences be the same as yours, or would they be phenomenally mirror‐inverted? I argue, first, that her experiences would be phenomenally the same as yours. I then show that this conclusion gives rise to a puzzle, one that I believe pushes us toward some surprising and philosophically significant conclusions about the nature of perception. When you have a typical visual experience as of something to your (...) left, the following three claims seem very plausible: (1) No one could have an experience phenomenally just like yours without thereby having an experience as of something to her left. (2) Your experience is veridical. (3) Your experience doesn't differ from that of your mirror‐inverted counterpart with respect to veridicality. But (1)‐(3) jointly contradict the claim that you and your mirror‐inverted counterpart would have the same experiences. I argue that any viable response to this puzzle will embrace the following disjunction: either there is a degree of independence between perceptual phenomenology and representational content, contrary to popular intentionalist views of perception, or spatial subjectivism is true, where spatial subjectivism is the view that the spatial properties presented in perception are either mind‐dependent or illusory.
