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.

In amodal completion the mind in some sense completes the visual perceptual representation of a scene by representing parts of the scene hidden behind other objects. Cognitive science has had a lot to say about how amodal completion occurs but has had little to say about the format of the representations involved and the way in which they represent. Some philosophers hold that amodal completions take the form of sensory imaginings of the occluded portions. This theory poses a puzzle for (...) both philosophy and neuroscience about how the occluded parts are imagined to be located relative to the unoccluded parts. A better theory begins with the observation that for many purposes it is useful to suppose that the mind contains mental models of three-dimensional structure. Visual perceptions and mental images may be conceived as mental models that represent external scenes by virtue of homomorphism and which possess both a deep aspect, representing both visible and occluded three-dimensional structure, and a perspectival aspect, representing only an arrangement of visible surfaces. In these terms we can explain various problem-solving abilities, such as the ability to imagine what a scene will look like from another point of view. Amodal completions can be treated as deep perceptual representations of three-dimensional structure. Thus amodal completions do not consist of mental imagery, but they can be used to generate mental imagery representing how a scene would look from alternative points of view. (shrink)

This paper introduces a novel conceptualisation of mental imagery; namely, that is grease for the mind’s gears (MGT). MGT is not just a metaphor. Rather, it describes an important and overlooked higher-order function of mental imagery: that it aids various mental faculties discharge their characteristic functional roles. MGT is motivated by reflection on converging evidence from clinical, experimental and social psychology and solves at least two neglected conceptual puzzles about mental imagery. The first puzzle concerns imagery’s architectural promiscuity; that is, (...) its ability to assist diverse mental faculties and perform many different functions when doing so. The second puzzle concerns how to square imagery’s architectural promiscuity with its psychopathological relevance; that is, its being a maintaining cause, and possibly even a partial constituent, of several psychological disorders, including post-traumatic stress disorder, bipolar disorder and major depressive disorder. Mental imagery helps and harms human psychology to extreme degrees and this is something that calls for elucidation. MGT says that instead of facing perplexing heterogeneities here, we instead face a significant unity. On this score, MGT is argued to be superior to the currently dominant conception of imagery in the philosophical literature; namely, as a perception-like state of mind. (shrink)

If I see, hear, or touch a sparrow, the sparrow seems real to me. Unlike Bigfoot or Santa Claus, it seems to exist; I will therefore judge that it does indeed exist. The “sense of existence” refers to the kind of awareness that typically grounds such ordinary judgments of existence or “reality.” The sense of existence has been invoked by Humeans, Kantians, Ideologists, and the phenomenological tradition to make substantial philosophical claims. However, it is extremely controversial; its very existence has (...) been called into question. This paper aims to clarify the nature and reality of the sense of existence by studying a psychiatric condition in which the sense appears to be disrupted: depersonalization disorder (DPD). (shrink)

Judgments of visual resemblance (‘A looks like B’), unlike other judgments of resemblance, are often induced directly by visual experience. What is the nature of this experience? We argue that the visual experience that prompts a subject looking at A to judge that A looks like B is a visual experience of B. After elucidating this thesis, we defend it, using the ‘phenomenal contrast’ method. Comparing our account to competing accounts, we show that the phenomenal contrast between a visual experience (...) that induces the judgment that A looks like B, and a visual experience that does not induce this judgment, is best explained by the fact that the former visually represents B, whereas the latter does not.

What is the relationship between perception and mental imagery? I aim to eliminate an answer that I call perceptualism about mental imagery. Strong perceptualism, defended by Bence Nanay, predictive processing theorists, and several others, claims that imagery is a kind of perceptual state. Weak perceptualism, defended by M. G. F. Martin and Matthew Soteriou, claims that mental imagery is a representation of a perceptual state, a view sometimes called The Dependency Thesis. Strong perceptualism is to be rejected since it misclassifies (...) imagery disorders and abnormalities as perceptual disorders and abnormalities. Weak Perceptualism is to be rejected since it gets wrong the aim and accuracy conditions of a whole class of mental imagery–projected mental imagery–and relies on an impoverished concept of perceptual states, ignoring certain of their structural features. Whatever the relationship between perception and imagery, the perceptualist has it wrong. (shrink)

Sensorimotor expectations concern how visual experience covaries with bodily movement. Sensorimotor theorists argue from such expectations to the conclusion that the phenomenology of vision is constitutively embodied: objects within the visual field are experienced as 3-D because sensorimotor expectations partially constitute our experience of such objects. Critics argue that there are two ways to block the above inference: to explain how we visually experience objects as 3-D, one may appeal to such non-bodily factors as expectations about movements of objects, not (...) the perceiver, or to the role of mental imagery in visual experience. But instead of using sensorimotor expectations to explain how objects are experienced within the visual field, we can instead use them to explain our experience of the visual field itself and, in particular, our experience of its limits; that is, our ever-present visual sense of there being more to see, beyond what’s currently within the visual field. Crucially, this inference from sensorimotor expectations to the constitutive embodiment of visual phenomenology is not threatened by the above two challenges. I thus present here a sensorimotor theory of the phenomenology of the visual field, that is, our experience of our visual fields as such. (shrink)

As far as I can see, there are two basic ways of cashing out the claim that intentionality is ultimately phenomenal: an indirect one, according to which the intentional content of an experiential intentional mental state is determined by the phenomenal character that state already possesses, so that intentionality is so determined only indirectly; a direct one, which centers on the very property of intentionality itself and can further be construed in two manners: either that very property is determined by (...) the above phenomenal character, or it is a sui generis phenomenal property, thereby giving its own contribution to the overall phenomenal character of that state. Yet neither way sounds ultimately satisfying. For the indirect way may work only under the assumption that intentionality is monadic. Since the direct way explicitly endorses this assumption, the indirect way must give pride of place to it. Yet the direct way seems to be unsuccessful, in any of its forms. Thus, the phenomenal intentionality research program ought to give way to another research program concerning intentionality. (shrink)

Alva Noë’s strategy to solve the puzzle of perceptual presence entirely relies on the principle of presence as access. Unaccessed or unattended parts or details of objects are perceptually present insofar as they are accessible, and they are accessible insofar as one possesses sensorimotor skills that can secure their access. In this paper, I consider several arguments that can be opposed to this claim and that are chiefly related to the modal status of action, i.e. the fact that the action (...) that would secure access to the absent aspects is a possibility, something that can be done. The main difficulty Noë’s account must face is –as several situations demonstrate– that the action that should be performed for the absent aspects to be actually accessed does not have to be itself available for these aspects to be perceptually present. What matters for the absent aspects to be present is not their de facto accessibility, but their de jure accessibility. To overcome those difficulties, I propose to rely on a ternary model of the role of action possibilities in perceptual awareness. This model builds on Husserl’s analysis of the role of perceptual circumstances in perception and connection between sense registering and horizontal intentionality. (shrink)
