: Fodor’s view of the mind is thoroughly computational. This means that the basic kind of mental entity is a “discursive” mental representation and operations over this kind of mental representation have broad architectural scope, extending out to the edges of perception and the motor system. However, in multiple epochs of his work, Fodor attempted to define a functional role for non-discursive, imagistic representation. I describe and critique his two considered proposals. The first view says that (...) images play a particular kind of functional role in certain types of deliberative tasks. The second says that images are solely restricted to the borders of perception, and act as a sort of medium for the fixing of conceptual reference. I argue, against the first proposal, that a broad-scope computationalism such as Fodor’s renders images in principle functionally redundant. I argue, against the second proposal, that empirical evidence suggests that non-discursive representations are learned through perceptual learning, and directly inform category judgments. In each case, I point out extant debates for which the arguments are relevant. The upshot is that there is motivation for limited scope computationalism, in which some, but not all, mental processes operate on discursive mental representations. Keywords: Computational Theory of Mind; Mental Representation; Perception; Mental Image; Jerry Fodor Fodor e le rappresentazioni mentali come immagini Riassunto: La concezione della mente di Fodor è rigorosamente computazionale, ossia le entità mentali di base sono rappresentazioni mentali “discorsive”. Le operazioni su queste rappresentazioni hanno un fine architettonico ampio, che va fino ai confini della percezione e del sistema motorio. In periodi diversi del suo lavoro, Fodor ha proposto due modi per definire un ruolo funzionale per la rappresentazione non-discorsiva come immagine. Tratterò criticamente entrambi. Per il primo, le immagini giocano un particolare tipo di ruolo funzionale in certi tipi di compiti deliberativi, mentre, per il secondo, sono relegate unicamente ai confini della percezione, agendo come medium per fissare il riferimento concettuale. Contro il primo sosterrò che un computazionalismo così ampio come quello di Fodor rende le immagini in principio funzionalmente ridondanti. Contro il secondo sosterrò che l’evidenza empirica suggerisce che le rappresentazioni non-discorsive vengono apprese percettivamente, agendo direttamente sui giudizi di categorizzazione. In entrambi i casi considererò gli argomenti più rilevanti nel dibattito corrente. Si vedrà che ci sono buone ragioni in favore di un computazionalismo più limitato, in cui alcuni processi mentali operano su rappresentazioni mentali discorsive.

: Fodor argues that perceptual representations are a subset of iconic representations, which are distinguished from symbolic/discursive representations. Iconic representations are nonconceptual and they do not support the abilities afforded by concepts. Iconic representations, for example, cannot support object individuation. If someone thinks that perception or some of its parts has imagistic NCC, they face the following dilemma. Either they will have to accept that this NCC does not allow for object individuation, but it represents instead conglomerations of properties (...) and at some stage of visual processing it must interface with cognition and its conceptual capacities for the visual objects to be individuated. Or, they will have to hold that the imagistic, NCC of perception, allows for object individuation. I opt for the second thesis because I think there is strong empirical evidence that objects are individuated during early vision. I also think that early vision individuates objects by means of, what I had previously called nonconceptual perceptual demonstrative reference. I argue, first, why Fodor’s view that iconic NCC does not enable object individuation is false. I also argue, contra Fodor, that early vision allows the perception of the cardinality of sets of objects. Keywords : Early Vision; Analog Representations; Object Individuation; Arithmetic Cognition; Cardinality of Sets L'individuazione di oggetti mediante il contenuto iconico: come è rappresentata la numerosità nella rappresentazione iconica? Riassunto: Per Fodor le rappresentazioni percettive sono un sottoinsieme delle rappresentazioni iconiche, distinte dalle rappresentazioni simbolico/discorsive. Le rappresentazioni iconiche sono nonconcettuali e non supportano le abilità richieste dai concetti. Le rappresentazioni iconiche, per esempio, non supportano l'individuazione di oggetti. Se si pensa che la percezione o qualche sua parte abbia un contenuto nonconcettuale come immagine, si ci si imbatte nel seguente dilemma. O si accetta che il NCC non permetta di individuare oggetti, ma che rappresenti conglomerati di proprietà e che si interfacci con la cognizione e le sue capacità concettuali, per individuare gli oggetti visivi. O si dice che l'immagine, il NCC, della percezione consenta di individuare oggetti. Propendo per la seconda tesi, poiché penso che ci sia solida evidenza empirica per cui gli oggetti vengono individuati durante le prime fasi della visione, in cui l’individuazione avviene mediante quanto definito come riferimento dimostrativo del contenuto nonconcettuale percettivo. Chiarirò le ragioni per cui la concezione di Fodor, per cui il contenuto nonconcettuale iconico non supporta l’individuazione di oggetti, è falsa. Inoltre, contra Fodor, sosterrò che le prime fasi della visione permettono la percezione della cardinalità di insiemi di oggetti. Parole chiave: Prime fasi della visione; Rappresentazioni analogiche; Individuazione di oggetti; Cognizione aritmetica; Cardinalità degli insiemi. (shrink)

In a recent paper, Karl Schafer argues that Hume's theory of mental representation has two distinct components, unified by their shared feature of having accuracy conditions. As Schafer sees it, simple and complex ideas represent the intrinsic imagistic features of their objects whereas abstract ideas represent the relations or structures in which multiple objects stand. This distinction, however, is untenable for at least two related reasons. Firstly, complex ideas represent the relations or structures in which the impressions that (...) are the objects of their simple components stand. Secondly, abstract ideas are themselves instances of complex ideas. I draw two important conclusions from these facts. Firstly, contra Schafer and Garrett, the Copy Principle, properly emended, constitutes the entirety of Hume's theory of mental representation. Secondly, whereas paradigm examples of complex ideas, e.g. ideas of spatial and temporal complexes, are structured by relations of contiguity, abstract ideas are those complex ideas instead structured by relations of resemblance. As such, they represent their objects not as spatially or temporally contiguous but rather as resembling. (shrink)

This dissertation works out a new approach to understanding what makes a representation pictorial and what makes a representation imagistic. Over the last thirty years, the most common approach to these problems has been to claim that what makes a representation pictorial is that normal perceivers can perceive it in certain ways. By contrast, my approach singles out structural features of representational systems as that which distinguishes pictures from other kinds of representations. Pictorial systems are those (...) that are transparent, relatively syntactically sensitive, relatively replete, and semantically rich. All pictures are images, but the converse relation does not hold because images need not be transparent, though they satisfy the weaker condition of being mimetic. This approach is similar to, but enjoys advantages over, Nelson Goodman's work on the topic. ;The account of what makes a representation pictorial or imagistic is then brought to bear on the imagery debate, which concerns whether the brain implements imagistic systems of representation, specifically in the early stages of perception. A review of what we know about the workings of the visual and auditory systems reveals that no representations in the brain are pictorial, though some are imagistic in quite limited respects. Though they fail to be imagistic in many interesting respects, the early stages of the visual and auditory systems are highly isomorphic to what they represent. ;The role of isomorphism in perceptual states has been much discussed in both philosophy and cognitive neuroscience. The last two chapters of the dissertation argue that perceptual representations of traditionally secondary qualities like colors and sounds are isomorphic to those properties to a lesser degree than representations of traditionally primary qualities like shapes. This distinction in how such properties are represented can affect out intuitions concerning the nature of those properties and the nature of perceptual experience. Furthermore, it is argued that isomorphism is an important feature of perceptual representations because of the role it plays in making information cognitively available. This role for isomorphism is maintained even if one is an information theorist, and therefore thinks that lawful causal generalizations fix the content of representations. (shrink)

[Pre-peer review draft available to download.] Our imaginative capacities shape the making of images, while the making of images has the ability to shape our imaginative capacities. What are the connections between vision and mental visual images that allow for this traffic between the contents of our minds and external images? And how are image-makers able to exploit the distinctive powers of imagery, to extend the modes of representation that are available to us, and hence also to extend the (...) resources upon which our imaginations can draw? The chapter explores various aspects of those issues. It starts by exploring “visual imagery” as a general category; and it identifies one very striking range of cases that encompasses both suitable mental and nonmental visual images. It develops a philosophical account of what is distinctive about the range of visual images thus identified. Subsequent sections then use the resulting ideas to investigate some of the ways in which various strategies for creating visual images exploit in remarkably inventive ways possibilities that are latent within the general phenomenon of imagistic representation.

The study of highly imagistic representations of Spinoza's philosophy found in popular, extra‐academic literature is essential for building a rational view on Spinoza's philosophy. Popular literature on Spinoza is an ineliminable condition of academic literature on Spinoza. The cementing of Spinoza's popularity belongs to a larger history of Spinoza's reception. This chapter examines two late‐nineteenth and early‐twentieth century works on Spinoza. Jules Prat's idiosyncratic blend of Spinozism and left‐wing French Republicanism stands out as a historically and philosophically rich approach (...) to Spinoza that has hardly been studied thus far. The chapter also examines the fiction of Isaac Bashevis Singer and Bernard Malamud. One common feature to Singer and Malamud is the way that they root their Spinozists in a Jewish world. In this, they are forerunners of the ongoing popular preoccupation with Spinoza's own relation to Judaism. (shrink)

I propose that an account of metaphor understanding which covers the full range of cases has to allow for two routes or modes of processing. One is a process of rapid, local, on-line concept construction that applies quite generally to the recovery of word meaning in utterance comprehension. The other requires a greater focus on the literal meaning of sentences or texts, which is metarepresented as a whole and subjected to more global, reflective pragmatic inference. The questions whether metaphors convey (...) a propositional content and what role imagistic representation plays receive somewhat different answers depending on the processing route. (shrink)

It is often observed that images—including mental images—are in some sense representationally ambiguous. Some, including Jerry Fodor, have added that mental images only come to have determinate contents through the contribution of non-imagistic representations that accompany them. This paper agrees that a kind of ambiguity holds with respect to mental imagery, while arguing (pace Fodor) that this does not prevent imagery from having determinate contents in the absence of other, non-imagistic representations. Specifically, I argue that mental images can (...) represent determinate types of outlays of properties without help from any non-imagistic representations, yet can only become involved in the representation of particular objects through pairing with a non-imagistic representation of the right sort. These points are defended through reflection on the “Picture Principle,” the nature of depiction, and general principles for typing and individuating mental states. (shrink)

Having, in previous papers, distinguished at least three forms of consciousness , I now further examine their differences. This examination has some surprising results. Having argued that neither C1 nor C2 is a phenomenological state?and so different from CN?I now show that CN itself is best thought of as a subclass of a larger state . CS is the set of image?representation states. CN is that set of CS states that we are also C2 about. I argue that CN (...) states should be considered a subset of CS states because they share with other CS states imagistic representational powers as opposed to the sentential ones of C1 and C2. And I argue that there are good reasons to consider any state which utilises imagistic representation as a sensation. I then show that the notion of an unconscious sensation makes sense if we think of it as a CS state that is not C2. More radically, I conclude that either it makes sense to say that there are unfelt sensations or there are felt sensations we are not conscious about. While there are good reasons for saying one or the other of these surprising things, I argue that the second, more radical sounding, alternative is actually better motivated?and not quite so surprising as it sounds.

William James described the stream of thought as having two components: (1) a nucleus of highly conscious, often perceptual material; and (2) a fringe of dimly felt contextual information that controls the entry of information into the nucleus and guides the progression of internally directed thought. Here I examine the neural and cognitive correlates of this phenomenology. A survey of the cognitive neuroscience literature suggests that the nucleus corresponds to a dynamic global buffer formed by interactions between different regions of (...) the brain, while the fringe corresponds to a set of mechanisms in the frontal and medial temporal lobes that control the contents of this global buffer. A consequence of this account is that there might be conscious imagistic representations that are not part of the nucleus. I argue that phenomenology can be linked to psychology and neuroscience and a meaningful way that illuminates both. (shrink)

Descartes is often thought to bifurcate sensory experience into two distinct cognitive components: the sensing of secondary qualities and the more or less intellectual perceiving of primary qualities. A closer examination of his analysis of sensory perception in the Sixth Replies and his treatment of sensory processing in the Dioptrics and Treatise on Man teIls a different story. I argue that Descartes offers a unified cognitive account of sensory experience according to which the senses and intellect operate together to produce (...) a fundamentally imagistic representation of the world in both its primary and secondary quality aspects. At stake here is not only our understanding of the cognitive structure of sensory experience but the relation of sense and intellect more generally in the Cartesian mind. The deep bifurcation in the Cartesian mind is not between the sensory perception of primary and secondary qualities but between sensory perception and purely intellectual perception. (shrink)

I examine a tension between temporal and spatial conceptualization of the genesis of the cosmos to show how chronological characterization of ‘beginnings’ occludes ontological interpretation of our existential orientations, to help my audience distinguish symbolic expressions of wonder that the cosmos exists from explanations for it. I bring together resources from multiple intellectual and religious traditions to perform a philosophy of religions that goes beyond the narrowness, intellectualism, and insularity of institutionalized philosophy of religion. I turn to Ibn Rushd, Tillich, (...) Pamela Sue Anderson, and Sara Ahmed to expose problems of confusing symbols with concepts. I bring Aristotle, Nagarjuna, Maimonides, Kant, Wittgenstein, and Nasr together in conversation about the notion of a ‘beginning.’ Through this, I seek to shift questions of cosmic linearity to questions of spatial symbols of inclusivity and suggest that our orientation toward chronology distracts us from inclusive ontologies, inadvertently getting us stuck in imagistic representation of a closed cosmos rather than critical conceptualization of open symbols for an inclusive cosmos.

Reasoning with diagrams is considered to be a peculiar form of reasoning. Diagrams are often associated with imagistic representations conveyed by spatial arrangements of lines, points, figures, or letters that can be manipulated to obtain knowledge on a subject matter. Reasoning with diagrams is not just ‘peculiar’ because reasoners use spatially arranged characters to obtain knowledge – diagrams apparently have cognitive surplus: they enable a quasi-intuitive form of knowledge. The present paper analyses the issue of diagrams’ cognitive value by (...) enquiring into the tradition of symbolic cognition developed by Leibniz, Lambert, and Kant. The proposal resulting from this enquiry is to question the idea that the cognitive value of diagrams lies solely in allowing evidence for inferences. The imaginative dimension of diagrams connects reasoning to doxastic attitudes of meditation and enquiry. (shrink)

When we imaginatively picture what might happen, we may take what we imagine to be either realistic or fantastic. A wine glass falling to the floor and shattering is realistic. A wine glass falling and morphing into a bird and flying away is fantastic. What does the distinction consist in? Two important necessary conditions are here defined. The first is a condition on the realistic representation of spatial configuration, grounded in an account of the imagistic representation of (...) spatial configuration. The second is a condition on the manner in which realistic courses of mental imagery may be grounded in remembered perceptions. This is defined in terms of an account of the representation of comparative similarity. This is an open access publication. (shrink)

Concept formation in science is a reasoned process, commensurate with ordinary problem-solving processes. An account of how analogical reasoning and reasoning from imagistic representations generate new scientific concepts is presented. The account derives from case studies of concept formation in science and from computational theories of analogical problem solving in cognitive science. Concept formation by analogy is seen to be a process of increasing abstraction from existing conceptual structures.

Case studies of diverse scientific fields show how scientists use a range of resources to generate new interpretative models and to establish their plausibility as explanations of a domain. They accomplish this by manipulating imagistic representations in particular ways. I show that scientists in different domains use the same basic transformations. Common features of these transformations indicate that general cognitive strategies of interpretation, simplification, elaboration, and argumentation are at work. Social and historical studies of science emphasize the diversity of (...) local contexts of practice. However, the existence of common strategies shows that this diversity masks an important repertoire of cognitive strategies. Scientists use this repertoire to adapt their representations to meet the cognitive demands of different contexts of practice. This paper considers the implications of this finding for the notion of scientists as cognitive agents in distributed knowledge-producing systems. (shrink)

In the last six or seven years, aphantasia has received attention from media outlets, television shows, and social networks. This alleged condition, however, has hardly been discussed in the philosophy of mind. In this paper, I assess some of the research conducted in cognitive science and provide, for the first time in the literature, a comprehensive assessment of possible explanations for aphantasia. Specifically, the hypotheses I submit for consideration ascribe the reports of absence of visual imagery to (i) a discrepancy (...) at the level of concepts, (ii) a failure of attentional mechanisms that modulate introspection, (iii) a lack of personal-level access to sub-personal imagistic representations, and (iv) an absence of sub-personal imagistic representations. I conclude that hypotheses (i) and (ii) can be rejected while hypotheses (iii) and (iv) can be accepted as defensible candidates for explaining aphantasia, although the latter is better suited to account for the available evidence in both comparative and absolute terms. Finally, I present some educated guesses and empirical research that could shed further light on the study of this condition. (shrink)

Experiences of qualia, subjective sensory-like aspects of stimuli, are central to imagistic representation. Following Raffman , qualia are considered to reflect experiential knowledge distinct from descriptive, abstract, and propositional knowledge; following Jackendoff , objective neural activity is distinguished from subjective experience. It is argued that descriptive physical knowledge does not provide an adequate accounting of qualia, and philosophical scenarios such as the Turing test and the Chinese Room are adapted to demonstrate inadequacies of accounts of cognition that ignore (...) subjective experience. Arguments by Dennett and others that qualia do not exist or that qualia do not provide additional explanatory power are addressed, and it is suggested that consideration of qualia is necessary in order to explain objective behavior. The hypotheses of functional equivalence, second-order isomorphism, and psychophysical complementarity between imagery and perception are discussed, and the ability of analog and schematic models of imagery to account for qualia is examined.

Pylyshyn rightly argues that the neuroscientific data supporting the involvement of the visual system in mental imagery is largely irrelevant to the question of the format of imagistic representation. The purpose of this commentary is to support this claim with a further argument.

In this analysis, I address the recent debate over the functional characteristics of mental imagery, in which the question is whether the format for imagistic representation is pictorial or sentential. I offer an account of imagery and cognition as an important aspect of the theory of mental representation, one which serves as a test for prevalent views of the nature of explanation in cognitive science. ;The first chapter articulates a functionalist theory of internal states. I argue for (...) the need to individuate mental states by virtue of their formal features, but in a way which is consistent with the fact that natural representational systems are self-interpreting. To that end, I describe a basic capacity for imaging which underlies any mental representation. ;In the second chapter, I discuss recent experiments and argue that a correct interpretation of the data cannot be determined on methodological grounds. The substantive argument against mental pictures is set forth and shown to rest upon two distinct assumptions. ;The third chapter aims to show that the argument that mental pictures are inherently ambiguous fails as an argument for an exclusively sentential format. I argue further that sentential states alone are insufficient to account for all rational behavior. The conclusion is that conceptual considerations do not preclude nondiscursive images, and a view of cognition as broader than computation favors them. I propose a logical foundation for an account of access to mental images-under-descriptions. ;The fourth chapter sets forth principles governing operations in which images might occur naturally. I argue that such an account depends upon the possibility of pictorial attitudes, mental features which are theoretically important for the notion of representational competence. ;In the fifth chapter, I show the relevance of the general account described in the previous chapter by applying it to diverse contexts: animal representation, hypothesis in perception, and self-representation.

Mental imagery has often been taken to be equivalent to “sensory imagination”, the perception‐like type of imagination at play when, for example, one visually imagines a flower when none is there, or auditorily imagines a music passage while wearing earplugs. I contend that the equation of mental imagery with sensory imagination stems from a confusion between two senses of mental imagery. In the first sense, mental imagery is used to refer to a psychological attitude, which is perception‐like in nature. In (...) the second sense, mental imagery refers to a mental content, which can be grasped via different attitudes. I will show that failure to acknowledge the distinction between these senses of mental imagery has muddled philosophical discussion. This distinction brings much needed clarity to debates where sensory imagination and mental imagery are invoked, shedding light on issues such as the nature of imagistic mental states, and the representational powers and limits of mental imagery. I will conclude by sketching a general attitudinal account of imagination that does justice to both senses of mental imagery, outlining a promising framework for understanding imagination. (shrink)

I argue for the existence of imaginative beliefs: mental states that are imaginative in format and doxastic in attitude. I advance two arguments for this thesis. First, there are imaginings that play the functional roles of belief. Second, there are imaginings that play the epistemic roles of belief. These arguments supply both descriptive and normative grounds for positing imaginative beliefs. I also argue that this view fares better than alternatives that posit distinct imaginative and doxastic states to account for the (...) same phenomena. Along the way, I demonstrate the theoretical significance of imaginative beliefs by showing how they pose a challenge for standard taxonomies of the mind, clarify the sense in which imagination is occurrent and voluntary, explain the justificatory role of the imagination, and point to a deep but underappreciated symmetry between imagistic and non-imagistic thought. (shrink)

Typical accounts of imagistic content have focused on the apparent analog character or continuous variability of images. In contrast, I consider the distinctive features of digital images, those composed of finite sets of discrete pixels. A rich source of evidence on digital imagistic content is found in the content-preserving algorithms that resize and reproduce digital images on computer screens and printers. I argue that these algorithms reveal a distinctive structural feature: digital images are always compositional (their parts contribute (...) systematically to overall content), but never inverse compositional (atomic parts may be replaced nonsynonymously without changing content). This indicates a sharp contrast with linguistic representations, which may or may not be compositional, and may or may not be inverse compositional. I argue this result sheds new light on the claim that imagistic content is inherently perspectival. (shrink)

How can thinking be effective in enabling us to meet our goals? If we answer this in terms of representation relations between thoughts and the world, then we are challenged to explain what representation is, which no one has been able to do. If we drop the appeal to representation, then it is hard to explain why certain inferences are good and others are not. This paper outlines a strategy for a nonrepresentationalist account of the way in (...) which the structure of reality may drive cognition. It begins by restricting our attention to certain paradigm cases of linguistically-mediated cooperative exchange. Second, it introduces a kind of nonconceptual thinking -- thinking in mental images. Third, in terms of imagistic cognition, the nonnormative conditions under which sentences are asserted and accepted is explained. Fourth, in terms of these conditions, the possibility of successful linguistic exchange in the paradigm cases is to be explained. Fifth, the strategy calls for an explanation how a language can be internalized and become a medium of intrapersonal thought. Finally, the norms of discourse can be conceived as norms that supervise the processes of linguistic exchange so explained. In this paper only the first three steps of the overall strategy will be carried out in any detail. But a strategy for completing the last three steps will be sketched. (shrink)

At least since Locke, philosophers and psychologists have usually held that concepts arise out of sensory perceptions, thoughts are built from concepts, and language enables speakers to convey their thoughts to hearers. Christopher Gauker holds that this tradition is mistaken about both concepts and language. The mind cannot abstract the building blocks of thoughts from perceptual representations. More generally, we have no account of the origin of concepts that grants them the requisite independence from language. Gauker's alternative is to show (...) that much of cognition consists in thinking by means of mental imagery, without the help of concepts, and that language is a tool by which interlocutors coordinate their actions in pursuit of shared goals. Imagistic cognition supports the acquisition and use of this tool, and when the use of this tool is internalized, it becomes the very medium of conceptual thought. (shrink)

The imagistic promotion of the iconic city form is increasingly achieved by the deployment of the CCTV webcam system. This not only presents new material to mediate people's engagement with this space, but also offers new ways to materialize its actual three-dimensional form. Recent design-based research conducted at the University of Technology, Sydney, shows that the function of the CCTV Internet cameras can be extended and adapted to provide a type of engagement with urban environments that subverts its more (...) representational role and converts it into one that is qualitative and experiential. The article will discuss how the performative aspects offered by this virtual environment can be productively employed by the Internet user to not only create a new type of engagement with public space, but also, ultimately, to curate this space. The article will also reveal how the strategic deployment of recently developed non-proprietary software can be used to intervene within the operational logic of the Internet camera to exploit its potential for use as a design tool. By the strategic recruitment of this software, raw virtual qualitative data from webcam images are processed to generate a formal response to civic space. This type of intervention, which utilizes the two-dimensional image as a platform for intervention within three-dimensional space, asks the designer to relinquish the techniques traditionally used to generate urban form and instead to capitalize upon the opportunities for material intervention offered by the spatial ambiguity of virtual and real-time environments. The exploration of the distortional optical properties associated with contemporary camera technology begins to suggest the development of a range of new techniques for design intervention that will continue to evolve in direct relationship to the technology they exploit. This article will therefore discuss how the utilization of the interactive potential of the CCTV system can produce a new understanding of urban space that replaces any symbolic role for form with the affect of form. This range of unprecedented techniques can be seen to offer a new paradigm for material intervention within both virtual and urban space. (shrink)

Diagrams are a form of spatial representation that supports reasoning and problem solving. Even when diagrams are external, not to mention when there are no external representations, problem solving often calls for internal representations, that is, representations in cognition, of diagrammatic elements and internal perceptions on them. General cognitive architectures—Soar and ACT-R, to name the most prominent—do not have representations and operations to support diagrammatic reasoning. In this article, we examine some requirements for such internal representations and processes in (...) cognitive architectures. We discuss the degree to which DRS, our earlier proposal for such an internal representation for diagrams, meets these requirements. In DRS, the diagrams are not raw images, but a composition of objects that can be individuated and thus symbolized, while, unlike traditional symbols, the referent of the symbol is an object that retains its perceptual essence, namely, its spatiality. This duality provides a way to resolve what anti-imagists thought was a contradiction in mental imagery: the compositionality of mental images that seemed to be unique to symbol systems, and their support of a perceptual experience of images and some types of perception on them. We briefly review the use of DRS to augment Soar and ACT-R with a diagrammatic representation component. We identify issues for further research. (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.

Mythopoetry, the imagistic voice of the muses which manifests in myth and natural poetry, has been invoked as an impression of ideal curriculum with which to cherish intimate, vital experience (and to oppose its exile from educational life). In this statement, I intend to see through the pleasant surface of the label, mythopoetry, to see what image may lie just out of sight, beyond the "inspired writing" that mythopoetry implies. Beyond words themselves, meaning is found in sound and in (...) expressive representation. “Music, when soft voices die, / Vibrates in the memory” (Shelley). (shrink)

Jonathan Walkan challenges cognitive science's dominant model of mental representation and proposes a novel, well-devised alternative. The traditional view in the cognitive sciences uses a linguistic model of mental representation. That logic-based model of cognition informs and constrains both the classical tradition of artificial intelligence and modeling in the connectionist tradition. It falls short, however, when confronted by the frame problem---the lack of a principled way to determine which features of a representation must be updated when new (...) information becomes available. So far, proposed alternatives, including the imagistic model, have not resolved the problem. Waskan proposes the Intrinsic Cognitive Models hypothesis, according to which representational states can be concpetualized as the cognitive equivalent of scale models.Waskan argues further that the proposal that humans harbor and manipulate cognitive counterparts to scale models offers the only viable explanation for what most clearly differentiates humans from other creatures: the capacity to engage in truth-preserving manipulation of representations. The ICM hypothesis, he claims, can be distinguished from sentence-based accounts of truth preservation in a way that is fully compatible with what is known about the brain. (shrink)

Feminism, poststructuralism, postcolonialism, and Marxism, among other critical approaches, have undermined traditional notions of aesthetics in recent decades. But questions of aesthetic judgment and pleasure persist, and many critics now seek a "return to aesthetics" or a "return to beauty." Janet Wolff advances a "postcritical" aesthetics grounded in shared values that are negotiated in the context of community. She relates this approach to contemporary debates about a committed politics similarly founded on the abandonment of certainty. Neither universalist nor relativist, the (...) "aesthetics of uncertainty" provides a discourse on beauty that contemporary critics can engage with and offers a basis for judgment that is committed to assigning value to works of art. Wolff explores her position through a range of topics: the question of beauty in relation to feminist critique; the problematic status of twentieth-century English art, visual representations of the Holocaust, Jewish identity as portrayed by the artist R. B. Kitaj, refugee artists and modernism in 1940s Britain, and the nature and appeal of imagistic thinking in sociology. She addresses the desire for certainty and the timeliness of doubt and concludes with a meditation on the intersection of aesthetics and ethics, arguing that ethical issues are very much implicated in aesthetic discourse.

Contemporary epistemology has assumed that knowledge is represented in sentences or propositions. However, a variety of extensions and alternatives to this view have been proposed in other areas of investigation. We review some of these proposals, focusing on (1) Ryle's notion of knowing how and Hanson's and Kuhn's accounts of theory-laden perception in science; (2) extensions of simple propositional representations in cognitive models and artificial intelligence; (3) the debate concerning imagistic versus propositional representations in cognitive psychology; (4) recent treatments (...) of concepts and categorization which reject the notion of necessary and sufficient conditions; and (5) parallel distributed processing (connectionist) models of cognition. This last development is especially promising in providing a flexible, powerful means of representing information nonpropositionally, and carrying out at least simple forms of inference without rules. Central to several of the proposals is the notion that much of human cognition might consist in pattern recognition rather than manipulation of rules and propositions. (shrink)

Explanations of animal problem-solving often represent our choices as limited to two: first, we can explain the observed behavior as a product of trained responses to sensory stimuli, or second, we can explain it as due to the animal’s possession of general rules utilizing general concepts. My objective in this essay is to bring to life a third alternative, namely, an explanation in terms of imagistic cognition.The theory of imagistic cognition posits representations that locate objects in a multidimensional (...) similarity space. It proposes that an animal’s expectations can be explained on the basis of the similarity of novel objects to objects previously encountered.The animal can predict the behavior of the novel object by producing a mental movie of the novel object by morphing it into an object, the behavior of which has previously been observed. After criticizing the theory of concept abstraction, I will identify some of the key elements of imagistic cognition.Then I will attempt to illustrate the utility of this conception of cognition by using it to explain the combination of successes and failures observed in monkeys in tool- mediated retrieval tasks (Fujita et al. 2003; Fujita et al. 2011) and in great apes in trap tube and trap table experiments (Martin-Ordas et al. 2008; Martin-Ordas et al. 2012).

People frequently report that, at times, their thought has a vocal character. Thinking commonly appears to be accompanied or constituted by silently ‘talking’ to oneself in inner speech. In this paper, we explore the specifically epistemic role of inner speech in conscious reasoning. A plausible position—but one I argue is ultimately wrong—is that inner speech plays asolelyfacilitative role that is exhausted by (i) serving as the vehicle of representation for conscious reasoning, and/or (ii) allowing one to focus on certain (...) types of objects or relations, e.g., causal relations, abstracta, counterfactuals, etc., or to consciously entertain structured propositional contents that it would be hard (or impossible) to focus on or entertain with representations in other (e.g., imagistic) formats. According to this position, inner speech doesn't figure as a justificatory element in our reasoning or as the partial epistemic basis of our conclusions—it merely facilitates reasoning through (i) and/or (ii). In contrast to the view that inner speech is amerefacilitator, I establish that (outside of potentially playing roles (i) and/or (ii)) the language we use itself serves as a crucial source of information in reasoning. In other words, we reason from propositions about the language we use in inner speech as opposed to exclusively reasoning from the semantic contents of the speech. My conclusion follows from how we use language as a cognitive tool to keep track of information, e.g., the contents of premises, lemmas, previous reasoning results, etc., in reasoning. (shrink)

A productive way to think about imagistic mental models of physical systems is as though they were sources of quasi‐empirical evidence. People depict or imagine events at those points in time when they would experiment with the world if possible. Moreover, just as they would do when observing the world, people induce patterns of behavior from the results depicted in their imaginations. These resulting patterns of behavior can then be cast into symbolic rules to simplify thinking about future problems (...) and to reveal higher order relationships. Using simple gear problems, three experiments explored the occasions of use for, and the inductive transitions between, depictive models and number‐based rules. The first two experiments used the convergent evidence of problem‐solving latencies, hand motions, referential language and error data to document the initial use of a model, the induction of rules from the modeling results, and the fallback to a model when a rule fails. The third experiment explored the intermediate representations that facilitate the induction of rules from depictive models. The strengths and weaknesses of depictive modeling and more analytic systems of reasoning are delineated to motivate the reasons for these transitions. (shrink)

Hegel makes claims about the relation of philosophy to religion that might raise concerns for those who want to locate his philosophy generally within the modern enlightenment tradition. For example, at the outset of his Lectures on Aesthetics he claims that philosophy “has no other object but God and so is essentially rational theology”.1 What might seem to placate worries here is that Hegel of course differentiates between the forms of religious and philosophical cognition in which such a content is (...) presented: while religion grasps this content in the form of imagistic or figurative representations [Vorstellungen], philosophy grasps it within conceptual thought, an attitude which might seem to align him with that found within the German enlightenment, for example, that found in Lessing and Kant. However, it seems undeniable that, in comparison to Kant, for example, Hegel employs forms of expression for the presentation of his own philosophical thought that are redolent with the type of imagistic and figurative locutions supposedly at home in religion. Moreover, the actual imagery employed seems to refer to the type of trinitarian version of Christianity that can seem antithetical to those forms of Christian thought that lent themselves to the sort of “demythologization” characteristic of the enlightenment attitude to religious doctrine. Such factors as these make it easy to portray Hegel’s philosophy as a type of irrationalist mysticism,2 or at least as a disguised theology with a content from revealed religion, and thus aligning him more to the spirit of the Counter-Enlightenment than the Enlightenment.

This paper brings neuroscientific experiments into relation with concepts from phenomenological philosophy to investigate phantom sensations from the perspective of embodied subjectivity. Using a mirror device to create intersensory effects in subjects experiencing phantom sensations, one can create illusions aiming at alleviating phantom pain. Neuroplasticity as a general property of the brain and cortical remapping as a specific mechanism underlying the success of this procedure are interpreted with the phenomenological notions of body image, body schema, and body memory. It is (...) argued that a phantom can be understood as an ambiguous unity of body-imagistic neglect and body-schematic remembering. This neurophenomenological approach highlights the significance of the polarity of subjective-objective embodied experience one the one hand, and the spatial and temporal horizons of the emergence of phantoms on the other. Thereby, implicit and explicit forms of remembering, habitual and reflective modes of behavioural and cognitive self-representation and -understanding can be compared according to how the body integrates its various sensations.

Human adults possess the extraordinary ability to produce mental imagery about a wide variety of non-occurrent events. We can, for example, simulate the perception of different places, different times, different possibilities, or others’ perspectives. Findings from cognitive psychology, neuropsychology, and cognitive neuroscience suggest that all of these capacities rely on the same neuro-cognitive mechanism: episodic simulation. This ability produces mental imagery by constructively recombining elements of past experiences to simulate event representations. However, if episodic simulation indeed produces mental imagery, it (...) remains unclear how the non-imagistic aspects of its outputs become cognitively determined. In this article, I argue that there are (at least) four such non-imagistic ‘dimensions’ of episodic simulation: specificity, temporal orientation, subjectivity, and factuality. Further, I propose an account of the mechanisms which might be responsible for determining where a given output of episodic simulation falls within this dimensional space. According to this view, episodic simulation relies on propositional ‘scope-operators’ either deployed as inputs to the simulation process itself or produced by post-hoc monitoring processes operating over its outputs. This view has consequences for how we should view the operation, development, and evolution of episodic simulation. (shrink)

Feminism, poststructuralism, postcolonialism, and Marxism, among other critical approaches, have undermined traditional notions of aesthetics in recent decades. But questions of aesthetic judgment and pleasure persist, and many critics now seek a "return to aesthetics" or a "return to beauty." Janet Wolff advances a "postcritical" aesthetics grounded in shared values that are negotiated in the context of community. She relates this approach to contemporary debates about a committed politics similarly founded on the abandonment of certainty. Neither universalist nor relativist, the (...) "aesthetics of uncertainty" provides a discourse on beauty that contemporary critics can engage with and offers a basis for judgment that is committed to assigning value to works of art. Wolff explores her position through a range of topics: the question of beauty in relation to feminist critique; the problematic status of twentieth-century English art, visual representations of the Holocaust, Jewish identity as portrayed by the artist R. B. Kitaj, refugee artists and modernism in 1940s Britain, and the nature and appeal of imagistic thinking in sociology. She addresses the desire for certainty and the timeliness of doubt and concludes with a meditation on the intersection of aesthetics and ethics, arguing that ethical issues are very much implicated in aesthetic discourse.

Abstract: This entry elucidates causal and constitutive roles that various forms of imagining play in human action. Imagination influences more kinds of action than just pretend play. I distinguish different senses of the terms “imagining” and “imagination”: imagistic imagining, propositional imagining, and constructive imagining. Each variety of imagining makes its own characteristic contributions to action. Imagistic imagining can structure bodily movement. Propositional imagining interacts with desires to motivate pretend play and mimetic expressive action. And constructive imagination generates representations (...) of possibilities and actions on the basis of which we choose what to do. [Version archived here is a penultimate draft.]. (shrink)

Is mental imagery pictorial? In Pylyshyn's view no empirical data provides convincing support to the “pictorial” hypothesis of mental imagery. Phenomenology, Pylyshyn says, is deeply deceiving and offers no explanation of why and how mental imagery occurs. We suggest that Pylyshyn mistakes phenomenology for what it never pretended to be. Phenomenological evidence, if properly considered, shows that mental imagery may indeed be pictorial, though not in the way that mimics visual perception. Moreover, Pylyshyn claims that the “pictorial hypothesis” is flawed (...) because the interpretation of “picture-like” objects in mental imagery takes a homunculus. However, the same point can be objected to Pylyshyn's own conclusion: if imagistic reasoning involves the same mechanisms and the same forms of representation as those that are involved in general reasoning, if they operate on symbol-based representations of the kind recommended by Pylyshyn (1984) and Fodor (1975), don't we need a phenomenological homunculus to tell an imagined bear from the real one?

The research on which the present paper makes a point in aimed at designing a cognitive model of Albert Einstein's discovery that is based on fundamental Einstein's publications and placed, ideally, at a meso-level, between macro-historical and micro-cognitive reconstructions (e.g. protocol analysis). As in a cognitive-historical analysis, we will trace some discovery heuristics in the construction of representations, that are on a continuum with those we employ in ordinary problem solving. Firstly, some theory-specific, reflexive heuristics—named orientative heuristics—are traced: inner perfection, (...) explain-or-assume, explanatory correspondence, and covariance/invariance. Then, other well-known abstractive heuristics as analogical and imagistic reasoning, thought experiment, limiting case analysis (e.g. Nersessian 1992) are shown occurring in Einstein's key-publications. A sketch of a socio-cognitive model for his discovery is then presented following two suggestions: (a) an idea of Van Fraassen about discovery phases, and (b) the Humean distinction between beliefs and ideas.

Christopher Gauker proposes that all cognition can be divided into nonconceptual image-based thought and conceptual language-based thought. The division between the two hinges on the representational powers of their respective mediums. I argue that a richer variety of representational states and processes is necessary in order to explain both human and nonhuman cognition. There are aspects of nonhuman cognition that cannot be explained simply by images, and there are aspects of human conceptual thought, particularly those dealing with causal reasoning, that (...) push us towards positing abstract systems of representation that are neither imagistic nor linguistic. Conceptual thought, then, occurs in its own proprietary inner code, not in images or words. (shrink)
