Category-specific impairments of object recognition and naming are among the most intriguing disorders in neuropsychology, affecting the retrieval of knowledge about either living or nonliving things. They can give us insight into the nature of our representations of objects: Have we evolved different neural systems for recognizing different categories of object? What kinds of knowledge are important for recognizing particular objects? How does visual similarity within a category influence object recognition and representation? What is the nature of our (...) semantic knowledge about different objects? We review the evidence on category-specific impairments, arguing that deficits even for one class of object cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients. The same apparent pattern of impairment can be produced by damage to different loci. According to a new processing framework for object recognition and naming, the hierarchical interactive theory, we have a hierarchy of highly interactive stored representations. HIT explains the variety of patients in terms of lesions at different levels of processing and different forms of stored knowledge used both for particular tasks and for particular categories of object. Key Words: category-specific deficits; functional imaging; hierarchical models; interactive activation models; neuropsychology; object recognition; perceptual and functional knowledge. (shrink)

The thesis is a study of the notion of intuition in the foundations of mathematics which focuses on the case of natural numbers and hereditarily finite sets. Phenomenological considerations are brought to bear on some of the main objections that have been raised to this notion. ;Suppose that a person P knows that S only if S is true, P believes that S, and P's belief that S is produced by a process that gives evidence for it. On a phenomenological (...) view the relevant evidence is provided by intuition , and this should be the case in either ordinary perceptual knowledge or in mathematical knowledge. Intuition is to be understood in terms of fulfillments of intentions. Knowledge is a product of intuition and intention. In the case of mathematical knowledge it is said that there is a construction for a mathematical statement S if and only if the intention expressed by S is fulfilled . Constructions are thus viewed as intuition processes that could actually or possibly be carried out. In elementary parts of mathematics they might be characterized in terms of certain classes of recursive functions. This view is discussed in the case where S is taken to be a singular statement about natural numbers or finite sets, and also where S is taken to be a general statement about such objects. The distinction between intuition of and intuition that is also investigated in this context. ;It is pointed out how on a phenomenological view a number of central problems about mathematical intuition can be avoided: problems about the analogousness of perceptual and mathematical intuition, about causal accounts of knowledge in mathematics, and about structuralism in mathematics. The bearing of the account on issues concerning constructivism and platonism is also discussed. (shrink)

This thesis offers a fresh interpretation and defense of epistemological disjunctivism about perceptual knowledge. I adopt a multilevel approach according to which perceptual knowledge on one level can enjoy factive rational support provided by perceptual knowledge of the same proposition on a different level. Here I invoke a distinction Ernest Sosa draws between ‘judgmental’ and ‘merely functional’ belief to articulate what I call the bifurcated conception of perceptual knowledge. The view that (...) results is a form of epistemological disjunctivism about perceptual knowledge specifically at the higher judgmental level, layered over a straightforward externalism about perceptual knowledge at the lower merely functional level. The first chapter orients the reader to epistemological disjunctivism— with particular emphasis on the ‘reflective epistemological disjunctivism’ defended by Duncan Pritchard with inspiration from John McDowell. Here I review the arguments for thinking such a proposal true, as well as highlight some problems and three emerging challenges for the view: what I call the internalist challenge, the new access challenge, and the ‘new evil genius’ challenge. These challenges largely inspire the chapters to follow. In the second chapter I present the positive proposal: a fresh interpretation of epistemological disjunctivism in terms of perceptual knowledge at the specifically judgmental level. I argue that this is a modification that epistemological disjunctivists should adopt since it inoculates their view against the internalist challenge: the challenge of explaining why perception should provide one with knowledge by providing one with motivating reasons for belief. In the third chapter I motivate the view further in connection with the more familiar ‘basis problem’ for epistemological disjunctivism. I argue that this approach supports a unique strategy for solving that problem: one that is consistent both with what is known as ‘the entailment’ thesis and the thought that we can reduce perceptual knowledge to a kind of rationally supported belief. In the fourth chapter I move to playing defense. I defend the proposal against the so-called ‘new evil genius’ challenge. This is the challenge to explain why subjects in pairs of ‘good’ and ‘bad’ cases can seem equally justified for sustaining their perceptual beliefs. I argue that what we are being sensitive to here, rather, is the fact that both subjects can be equally epistemically responsible and/or reasonable for believing what they do. Before concluding this chapter I also offer an error theory. In the fifth chapter I defend the proposal against the new access challenges raised in chapter one. These alleged challenges for epistemological disjunctivism arise specifically for versions of reflective epistemological disjunctivism that hold that one’s rational support for perceptual beliefs is not only factive but reflectively accessible as well. Rather than address the challenges head on, I try to dislodge the thought they depend upon—viz., that one’s factive rational support for perceptual beliefs is reflectively accessible to the subject. Here I argue that the reflective accessibility of one’s factive rational support is actually a wheel turning idly in the debate with the underdetermination-based radical sceptic—so that we can simply drop it without consequence. The result is an epistemological disjunctivism that is immune to access problems. I then offer a final summary and conclude. At the end of this thesis I have attached an appendix, which is an excursion into religious epistemology and an exploration of a form of religious epistemological disjunctivism. Here I apply the epistemological disjunctivist insight to the case of religious perception in order to defend the idea that one can offer independent rational support for theistic belief by appealing to religious beliefs that are justified on the basis of religious experiences. This appendix chapter is in keeping with the general spirit of the thesis insofar as it seeks to developed epistemological disjunctivism in new and fruitful directions. (shrink)

What is the relation between a perceptual experience of an object X as being red, and one's belief, if any, as to the nature of that experience? A traditional Cartesian view would be that, if indeed object X does seem to be red to oneself, then one's resulting introspective belief about it could only be a _conforming _belief, i.e., a belief that X perceptually seems to be _red _to oneself--rather than, for instance, a belief that X perceptually seems to (...) be green to oneself instead. On such a Cartesian view, our introspective certainly about our own thoughts extends also to our perceptual experiences as to how things seem to be to us, so that our resulting introspective beliefs about our phenomenal states also count as knowledge of them.

Many neuroimaging studies of semantic memory have argued that knowledge of an object's perceptual properties are represented in a modality-specific manner. These studies often base their argument on finding activation in the left-hemisphere fusiform gyrus-a region assumed to be involved in perceptual processing-when the participant is verifying verbal statements about objects and properties. In this paper, we report an extension of one of these influential papers-Kan, Barsalou, Solomon, Minor, and Thompson-Schill (2003 )-and present evidence for an amodal (...) component in the representation and processing of perceptual knowledge. Participants were required to verify object-property statements (e.g., "cat-whiskers?"; "bear-wings?") while they were being scanned by functional magnetic resonance imaging (fMRI). We replicated Kan et al.'s activation in the left fusiform gyrus, but also found activation in regions of left inferior frontal gyrus (IFG) and middle-temporal gyrus, areas known to reflect amodal processes or representations. Further, only activations in the left IFG, an amodal area, were correlated with measures of behavioural performance. (shrink)

Despite the fact that attention is a core property of all perceptual and cognitive operations, our understanding of its neurophysiological mechanisms is far from complete. There are many theoretical models that try to fill this gap in knowledge, though practically all of them concentrate only on either involuntary (bottom-up) or voluntarily (top-down) aspect of attention. At the same time, both aspects of attention are rather integrated in the living brain. In this chapter we attempt to conceptualise both aspects (...) of attentional state within the theory of Operational Architectonics of brain and mind functioning, which provides a plausible theoretical basis for neurophysiological understanding of how attention is brought to existence in the living brain.

Knowledge before belief ascription? Yes and no (depending on the type of “knowledge” under consideration). In an influential paper, Jonathan Phillips and colleagues have recently presented a fascinating and provocative big picture that challenges foundational assumptions of traditional Theory of Mind research (Phillips et al., 2020). Conceptually, this big picture is built around the main claim that ascription of knowledge is primary relative to ascription of belief. The primary form of Theory of Mind (ToM) thus is so-called (...) factive ToM that centres around knowledge-related mental states that are true rather than meta-representational ToM that centres around subjective epistemic states like belief that may or may not be true (Nagel, 2017; Phillips & Norby, 2019). Empirically, Phillips and colleagues build on converging findings from different areas: Ample research in developmental psychology shows that children track who has had informational access to events (and thus knows about the events) before they keep track of others’ potentially false beliefs (e.g., Perner & Roessler, 2012). Many studies from comparative psychology have found evidence that non-human great apes keep track of others’ perceptual and informational access while there is no convincing evidence that they keep track of others’ beliefs (Horschler et al., 2020; Martin & Santos, 2016; Call & Tomasello, 2008). And, work from cognitive psychology and experimental philosophy suggests that adults are faster, for example, to judge what others know than to judge what they believe (Phillips et al., 2018).In this commentary, we would like to critically evaluate and friendly amend the claims put forward by Phillips and colleagues. Conceptually, while we agree that some form of factive Theory of Mind is primary, we would like to raise doubts whether this primary factive ToM already involves full-fledged knowledge ascription. Empirically, we will point to potential test cases that are suitable to test Phillips and colleagues’ account against the friendly amendment proposed here. Is knowledge ascription really primary relative to belief ascription?We agree that the empirical findings reviewed by Phillips and colleagues do make a strong case for the conjecture that some form of factive ToM is indeed (phylogenetically, ontogenetically, and cognitively) primary. But we suspect that this claim, in unqualified form, may be somewhat incomplete and misleading. There is not necessarily one unitary form of factive ToM, and one notion of “knowledge“ in play across development and evolution, and perhaps not even in adults‘ Theory of Mind. This suspicion builds on several foundations: First, from an empirical point of view there have been, as highlighted by the authors, characteristic U-shaped developmental curves in some tasks of factive ToM – often a reliable indicator that different underlying processes are in play (Karmiloff-Smith, 1992). Second, from a theoretical point of view, conceptual change and dual process approaches to ToM and other forms of social cognition have highlighted the possibility of more complex developmental trajectories such that earlier and more basic forms of a conceptual competence may be supplemented and superseded by later and more sophisticated refinements (e.g. Apperly & Butterfill, 2009; Perner, 1991). For the case of factive ToM, it may be that there is a basic and primitive notion of “knowledge“ in place early in ontogeny (and perhaps phylogenetically more ancient) that shares some of the essential features of our mature “knowledge” concept: “knowledge” in this broad sense, as emphasized by the authors, is factive, not modality-specific, and allows for representations of egocentric ignorance. For this basic concept, the slogan “knowledge before belief“ may well be true. However, this basic concept need not yet be our mature notion of knowledge proper and thus this basic form of factive ToM may fall crucially short of our adult form of factive ToM. Why? Because essential elements of our mature concept of knowledge are still missing: First of all, while so-called Gettier cases and other considerations make clear that knowledge does not reduce to justified true belief (one can have justified true beliefs that still do not amount to knowledge; Gettier, 1963), according to many accounts knowledge at least presupposes justified true belief. Correspondingly, ascription of knowledge would thus presuppose ascription of belief. Now, we understand that this is one of the very traditional assumptions that Phillips and colleagues challenge, and given space restrictions we will not focus on it here any further (see, e.g, Rose & Schaffer, 2013). But there is a second crucial aspect of knowledge proper that is missing from the basic notion: knowledge proper is aspectual, and consequently reports of knowledge proper are intensional, while neither seems to be the case of basic knowledge and reports of it. Knowledge proper is aspectual in the following sense: whether or not someone knows something depends on how, under which aspects, she has had informational access to a given scene. Suppose Eve has seen Clark Kent enter the house. Does she know that Superman is in the house? It depends. If she knows about the identity Clark Kent = Superman, she does, otherwise she does not. Consequently, knowledge ascription is intensional in the sense that the substitution of co-referential terms is not necessarily truth-value preserving: “Eve knows that Clark Kent is in the house“ does not imply “Eve knows that Superman is in the house”.Now, from the point of view of cognitive development, much research suggests that children’s appreciation of the aspectuality of propositional attitudes (and the intensionality of propositional attitude reports) develops in protracted ways not before the age of four (e.g., Apperly & Robinson, 1998; Rakoczy et al., 2015; Proft et al., 2019). In fact, recent studies suggest that around age four children undergo a fundamental and coherent cognitive revolution: they acquire a solid meta-representational notion of propositional attitudes that allows them to ascribe subjective aspectual representations that may or may not be accurate: Children come to solve false belief tasks that require belief ascription at the same time as tasks that require an understanding of aspectuality, and there is strong convergence/correlation between these different tasks (Rakoczy, 2017; Rakoczy et al., 2015). These considerations thus evoke a somewhat modified picture of the developmental course of factive Theory of Mind: Some form of factive ToM, indeed, comes first (developmentally and phylogenetically). In this primary stage, subjects track agents‘ cognitive relations to the world that display some of the essential signatures of knowledge proper (factive; not modality-specific; allow for representations of egocentric ignorance). Various approaches in ToM research over the last years have aimed at describing this basic form of knowledge-like relations, for example in terms of “cognitive connections“ (Flavell, 1988), “registration“ (Apperly & Butterfill, 2009), “experiential records“ (Perner & Roessler, 2012) or “awareness relations“ (Martin & Santos, 2016). While differing in focus and details, all these accounts converge in stressing one crucial point: this early form of factive ToM allows observer to keep track of what others have or have not witnessed and, in this sense, what they do or do not know. It allows, in other words, so-called “Level I” perspective-taking (Flavell, 1977): understanding what others see. But this early form of factive ToM still falls short of knowledge ascription proper because it lacks an appreciation of the essential aspectuality of propositional attitudes in general and of knowledge in particular. In other words, it does not yet allow for “Level II” perspective-taking: understanding how different agents may represent a given scene (Fizke et al., 2017; Low & Watts, 2013; Oktay-Gür et al., 2018). Only later, around age 4, do children then develop the new meta-representational framework of propositional attitudes that goes beyond basic factive ToM. Once they have this framework and thus an understanding of aspectuality at hand, they can extend their initial and primary factive ToM to acquire the mature concept of knowledge (as at least presupposing true, justified belief, where belief is necessarily aspectual). So, while basic knowledge ascription indeed precedes belief ascription, full-blown attribution of aspectual knowledge develops in tandem with belief attribution. Or in other words: basic factive ToM precedes full-blown meta-representational ToM but full-blown factive ToM does not (since it is itself a part of full-blown meta-representational ToM). Empirical outlookThis slightly modified picture raises many interesting new empirical questions, and makes competing predictions relative to the picture put forward by Phillips and colleagues: From developmental and comparative perspectives, the modified picture would predict that “knowledge before belief” only applies for a circumscribed set of knowledge-related situations: those in which knowledge ascription does not require sensitivity to the aspectuality of knowledge (does not require distinguishing, for example, “Does she know that Clark Kent is in the house?” vs. “Does she know that Superman is in the house?”) and is limited to Level I perspective-taking. Young children before the age of four and non-human primates should be able to solve such non-aspectual knowledge ascription problems. But only older children from around age four, once they have acquired the full-fledged conceptual apparatus of meta-representation, should be able to handle aspectual knowledge ascription. Regarding adult functioning, the most fundamental question is: Do adults operate with one unitary factive ToM, as Phillips and colleagues assume? Or are there two kinds of factive ToM throughout the lifespan, as our modified picture suggests? In particular, does the more basic version remain in operation in adulthood, perhaps even as the default mode, that reveals itself under conditions of speeded responses, limited cognitive resources etc.? If the latter were true, specific performance patterns should be found. First, results such that adults are faster at knowledge ascription than at belief ascription (as found in Phillips et al., 2018) should be restricted to designs where knowledge ascription does not require any considerations of aspectuality. In such designs (as they were used in Phillips et al., 2018), subjects can make use of their primordial (non-aspectual) factive ToM in knowledge ascription, but have to use their full-fledged (aspectual) ToM in belief ascription. However, in new cases in which knowledge ascription is potentially aspectual (“Does Eve know that Superman is in the house?”), the speed difference between knowledge and belief ascription should vanish since both now require full-fledged (aspectual) ToM. Second, and relatedly, fast factive ToM should have characteristic signature limits to do with the lacking appreciation of aspectuality (Apperly & Butterfill, 2009; Low et al., 2016): Subjects under speeded conditions (or in dual task formats in which their central cognitive resources are taxed) should be unable to systematically distinguish between “Eve knows that Clark Kent is the house” (true) and “Eve knows that Superman is in the house” (possibly true). No such signature limits should be expected, in contrast, under reflective conditions in which subjects can use their full-fledged and mature factive ToM. Interestingly, these hypothetical developmental and adult performance patterns would correspond to similar patterns found in the domain of modal judgments. Adults, it seems, have two notions of modality at their disposal: a more primitive (ontogenetically old) default notion that does not differentiate between descriptive and normative modals and thus yield characteristic signature limits; and more differentiated and nuanced notions (ontogenetically more recent) that do sharply distinguish between different forms of modality. What works fast and gets addressed in speeded tasks is the primitive default notion (in speeded tasks, adults tend to confuse what is possible with what is permitted, for example, in the way very young children do) whereas the more nuanced notions reveal themselves in reflective task settings in which adults are not subject to such confusions (Phillips & Cushman, 2017). Modality judgments and factive ToM may thus reveal striking analogies. Just like in the area of modality, then, there may be basic and default factive ToM, present from early on and in operation throughout the lifespan in speeded responses (and under other conditions of limited cognitive resources), and more sophisticated factive Theory of Mind that develops later on the basis of full-fledged meta-representation and that reveals itself in more reflective judgements.

The purpose of this paper is two-fold. First, it aims at developing a preliminary typology of subconscious, tacit mechanisms that underlie the conscious exercise of practical skills as well as the formation and functioning of conscious mental representations such as perceptual experiences, mental images, explicitly held beliefs and explanatory hypotheses. Second, it employs the typology to consider whether these tacit mechanisms can be examined and explicated by what Ryszard Wójcicki calls heuristic theorizing or heuristic reasoning , i.e., by a (...) cognitive procedure whose job is to study one\'s tacit or personal knowledge.

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statis- tics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement record- ing systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During (...) class='Hi'>perceptual experience, association areas in the brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The stor- age and reactivation of perceptual symbols operates at the level of perceptual components – not at the level of holistic perceptual expe- riences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a com- mon frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspec- tion (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and ab- stract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinato- rially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a per- ceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal sym- bol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored. (shrink)

Taking perceptual experience to consist in a relation of acquaintance with the sensible qualities, I argue that the state of being acquainted with a sensible quality is intrinsically a form of knowledge, and not merely a means to more familiar kinds of knowledge, such as propositional or dispositional knowledge. We should accept the epistemic claim for its explanatory power and theoretical usefulness. That acquaintance is knowledge best explains the intuitive epistemic appeal of ‘Edenic’ counterfactuals involving (...) unmediated perceptual contact with reality (cf. Chalmers, in: Gendler, Hawthorne (eds) Perceptual experience, Oxford University Press, 2006). It explains the elusiveness of knowledge gained through new acquaintances. It coheres with the knowledge-like functional role of acquaintance in the special context of evaluative beliefs and evaluative reasoning, where the objects of acquaintance serve as evidence and inferential basis. And, finally, taking acquaintance to be knowledge is theoretically fruitful: it helps vindicate claims about the relationship between knowledge and concern for others we already find intuitive or outright accept. After developing a novel case for the epistemic claim, I respond to two familiar objections against it: namely, (1) that there are no pre-propositional, pre-conceptual cases of perceptual experience that remain epistemically relevant (Sellars in Empiricism and the philosophy of mind, Routledge, 1968, McDowell, in: Lindgard (ed) John McDowell: Experience, norm, and nature, Blackwell, 2008); and (2) that the category of knowledge appears gerrymandered once we add ‘object’ knowledge to the epistemological mix (Farkas, in: Knowles, Raleigh (eds), Acquaintance: new essays, Oxford University Press, 2019).

Shape and slant judgments of rotated or frontoparallel ellipses were elicited from three groups of 10 subjects. A masking stimulus was introduced to control processing time. Backward masking trials were presented with interstimulus intervals of 0, 25, and 50 msec, Reduction of processing time altered shape judgments in the direction of projective shape and slant judgments in the direction of frontoparallelness. This finding is consistent with the shape-slant invariance hypothesis. In order to study the effects of processing load, one group (...) of subjects was given prior knowledge of the kind of judgment to be made on each trial, one group had no prior knowledge, and a third group made both judgments on each trial. The effects of the processing load manipulation were interpreted in terms of the role of attention in perceptual encoding. Consistent with previous findings, allocation of attention did not affect perceptual encoding. (shrink)

This thesis aims to study the origins of interiority from an externalist perspective. The process by which self-knowledge is formed is considered in relation to the development of the first-person perspective. From a first-person perspective, one is capable of self-referring and knowing one's own mental and physical states. Self-consciousness and self-knowledge are discussed in relation to Descartes' idea of first-person authority. The Cartesian idea contends that the first-person perspective has privileged and non-empirical access to one's own mental state. (...) On the contrary, externalism's central thesis contends that the content of one's own mental state originates from interactions with the environment, thus, there is no privileged access of one's own mental state. Thus, the externalist's thesis puts into question the Cartesian idea of privileged epistemic access of the first person. The perceptual externalism of Davidson, for example, proposes a triadic solution to the origins of self-knowledge. Davidson's thesis is presented as reconciling self-knowledge and the basic externalist ideas. Two externalist models on the origins of self-knowledge are further discussed: 1) ecological models proposing a development of a sense of self as a function of interactions with the environment; 2) the psychological model of Winnicott proposing that the developing sense of self arises from the triadic relation between self, others, and transitional object(s). We defend the thesis that Winnicott's model is the most apt at describing the Davidsonian externalist model of the origins of self-knowledge. (shrink)

Epistemological disjunctivism says that one can know that p on the rational basis of one’s seeing that p. The basis problem for disjunctivism says that that can’t be since seeing that p entails knowing that p on account of simply being the way in which one knows that p. In defense of their view disjunctivists have rejected the idea that seeing that p is just a way of knowing that p (the SwK thesis). That manoeuvre is familiar. In this paper (...) I explore the prospects for rejecting instead the thought that if the SwK thesis is true then seeing that p can’t be one’s rational basis for perceptual knowledge. I explore two strategies. The first situates disjunctivism within the context of a ‘knowledge-first’ approach that seeks to reverse the traditional understanding of the relationship between perceptual knowledge and justification (or rational support). But I argue that a more interesting strategy situates disjunctivism within a context that accepts a more nuanced understanding of perceptual beliefs. The proposal that I introduce reimagines disjunctivism in light of a bifurcated conception of perceptual knowledge that would see it cleaved along two dimensions. On the picture that results perceptual knowledge at the judgemental level is rationally supported by perceptual knowledge at the merely functional or ‘animal’ level. This supports a form of disjunctivism that I think is currently off the radar: one that’s consistent both with the SwK thesis and a commitment to a traditional reductive account of perceptual knowledge.

Tyler Burge notably offers a truth‐first account of perceptual entitlement in terms of a priori necessary representational functions and norms: on his account, epistemic normativity turns on natural norms, which turn on representational functions. This paper has two aims: first, it criticises Tyler Burge's truth‐first a priori derivation on functionalist and value‐theoretic grounds. Second, it develops a novel, knowledge‐first a priori derivation of perceptual entitlement. According to the view developed here, it is a priori that we are (...) entitled to believe the deliverances of our perceptual belief formation system, in virtue of the latter's constitutive function of generating knowledge.

ABSTRACT: Central to both James’s earlier psychology and his later philosophical views was a recurring distinction between percepts and concepts. The distinction evolved and remained fundamental to his thinking throughout his career as he sought to come to grips with its fundamental nature and significance. In this chapter, I focus initially on James’s early attempt to articulate the distinction in his 1885 article “The Function of Cognition.” This will highlight a key problem to which James continued to return throughout his (...) later philosophical work on the nature of our cognition, including in his famous “radical empiricist” metaphysics of “pure experience” around the turn of the century. We shall find that James grappled insightfully but ambivalently with the perceptual and conceptual dimensions of the “knowledge relation” or the “cognitive relation,” as he called it—or what, following Franz Brentano, philosophers would later call our object-directed thought or intentionality more generally. Some philosophers have once again returned to James’s work for crucial insights on this pivotal topic, while others continue to find certain aspects of his account to be problematic. What is beyond dispute is that James’s inquiries in this domain were both innovative and of lasting significance. (shrink)

Happiness, like other basic emotions, has visual properties that create the conditions for happiness to be perceived in others. This is to say that happiness is perceivable. Its visual properties are to be identified with those facial expressions that are characteristic of happiness. Yet saying that something is perceivable does not suffice for us to conclude that it is perceived. We therefore need to show that happiness is perceived. Empirical evidence suggests that the visual system functions to perceive happiness as (...) well as other basic emotions. Experiences that can be had simply by virtue of how the perceptual system functions are known as observations. I will thus argue that visual experiences in which we become aware of others’ happiness are observations. This approach will provide the necessary conceptual framework to show that we have perceptual knowledge of others’ happiness. (shrink)

The information in the working environment of industrial Internet is characterized by diversity, semantics, hierarchy, and relevance. However, the existing representation methods of environmental information mostly emphasize the concepts and relationships in the environment and have an insufficient understanding of the items and relationships at the instance level. There are also some problems such as low visualization of knowledge representation, poor human-machine interaction ability, insufficient knowledge reasoning ability, and slow knowledge search speed, which cannot meet the needs (...) of intelligent and personalized service. Based on this, this paper designs a cognitive information representation model based on a knowledge graph, which combines the perceptual information of industrial robot ontology with semantic description information such as functional attributes obtained from the Internet to form a structured and logically reasoned cognitive knowledge graph including perception layer and cognition layer. Aiming at the problem that the data sources of the knowledge base for constructing the cognitive knowledge graph are wide and heterogeneous, and there are entity semantic differences and knowledge system differences among different data sources, a multimodal entity semantic fusion model based on vector features and a system fusion framework based on HowNet are designed, and the environment description information such as object semantics, attributes, relations, spatial location, and context acquired by industrial robots and their own state information are unified and standardized. The automatic representation of robot perceived information is realized, and the universality, systematicness, and intuition of robot cognitive information representation are enhanced, so that the cognition reasoning ability and knowledge retrieval efficiency of robots in the industrial Internet environment can be effectively improved.

The chapter deals with the notion of phenomenal realness, which was first systematically explored by Albert Michotte. Phenomenal realness refers to the impression that a perceptual object is perceived to have an autonomous existence in our mind-independent world. Perceptual psychology provides an abundance of phenomena, ranging from amodal completion to picture perception, that indicate that phenomenal realness is an independent perceptual attribute that can be conferred to perceptual objects in different degrees. The chapter outlines a theoretical (...) framework that appears particularly well-suited for dealing with corresponding phenomena. According to this framework, perception can be understood as a triggering of conceptual forms by sensor inputs. It is argued that the attribute of phenomenal realness is based on specific types of internal evaluation functions which deal with the segregation of causes conceived as ‘external’ from those conceived as ‘internal’. These evaluation functions integrate different internal sources of ‘knowledge’ about the potential causes for the activation of conceptual forms and provide markers by which conceptual forms can be tagged as ‘external world objects’.

Merging the information from different senses is essential for successful interaction with real-life situations. Indeed, sensory integration can reduce perceptual ambiguity, speed reactions, or change the qualitative sensory experience. It is widely held that integration occurs at later processing stages and mostly in higher association cortices; however, recent studies suggest that sensory convergence can occur in primary sensory cortex. A good model for early convergence proved to be the auditory cortex, which can be modulated by visual and tactile stimulation; (...) however, given the large number and small size of auditory fields, neither human imaging nor microelectrode recordings have systematically identified which fields are susceptible to multisensory influences. To reconcile findings from human imaging with anatomical knowledge from nonhuman primates, we exploited high-resolution imaging (functional magnetic resonance imaging) of the macaque monkey to study the modulation of auditory processing by visual stimulation. Using a functional parcellation of auditory cortex, we localized modulations to individual fields. Our results demonstrate that both primary (core) and nonprimary (belt) auditory fields can be activated by the mere presentation of visual scenes. Audiovisual convergence was restricted to caudal fields [prominently the core field (primary auditory cortex) and belt fields (caudomedial field, caudolateral field, and mediomedial field)] and continued in the auditory parabelt and the superior temporal sulcus. The same fields exhibited enhancement of auditory activation by visual stimulation and showed stronger enhancement for less effective stimuli, two characteristics of sensory integration. Together, these findings reveal multisensory modulation of auditory processing prominently in caudal fields but also at the lowest stages of auditory cortical processing. (shrink)

In this paper, I provide a probabilistic account of factual knowledge, based on the notion of chance, which is a function of an event given a prior history. This account has some affinity with my chance account of token causation, but it neither relies on it nor presupposes it. Here, I concentrate on the core cases of perceptual knowledge and of knowledge by memory. The analysis of knowledge presented below is externalist. The underlying intuition guiding (...) the treatment of knowledge in this paper is that knowledge boils down to high token discriminative indicativeness. Type indicativeness or type discriminability are neither necessary nor sufficient for knowledge: the token aspect comes out in the strong dependence on the specific circumstances and chances of the case. The main condition of the first section, the indicativity condition, properly refined, yields pertinent indicativity as a main constituent. Very roughly, it involves the chance of the content clause p being higher given the subject's believing that p than otherwise. The discriminability condition in question captures the sense of discriminability appropriate for knowledge and yield the indicativity condition: it is an extension of the indicativity condition KI. Roughly, the subject’s ability to discriminate the object in front of her being red from its being green is captured by holding fixed, in the indicativity condition, the condition “the object in front of her is red or green.” A major element in the analysis is the so-called Contrast Class, which governs the scope of discriminability. This is the class of features that have to be taken into account in the discriminability condition, and it is characterized by two constraints. Very roughly, according to the first constraint, for a feature to be in the contrast class, it must not represent a sub-type of the predicate in the content clause. According to the second constraint, which is a central condition with many implications, the chance that the object specified in the content clause has a feature represented in the contrast class must not under the circumstances be too low. This constraint, within the framework of the discriminability condition, brings out a major constitutive aspect of knowledge: knowledge amounts to a limited vulnerability to mistakes of the belief in question under the circumstances at hand. The contrast class plays a major role in my treatment of skepticism. The second constraint on the Contrast Class together with the VHP condition below bring out precisely the way in which perceptual knowledge is fallible. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.2 (2001) 312-314 [Access article in PDF] Shook, John R. Dewey's Empirical Theory of Knowledge and Reality.The Vanderbilt Library of American Philosophy. Nashville: Vanderbilt University Press, 2000. Pp. ix + 316. Cloth, $46.00; Paper, $22.95. The current renaissance of American pragmatism, and John Dewey's philosophy in particular, began two decades ago with Richard Rorty's refashioning of Dewey as a postmodernist who renounces (...) the "professional philosophy" of metaphysics and epistemology for the fluidity of conversation in the life and growth of a community. This depiction, though praised for rekindling Dewey's star, has been widely challenged by subsequent commentators. Ralph Sleeper's 1986 The Necessity of Pragmatism persuasively argues that Dewey reconfigures, rather than renounces, the logical and metaphysical grounds of knowledge. Despite an archaic Hegelian vocabulary that misleadingly suggests idealism and antirealism, Sleeper finds Dewey advancing a genuine metaphysics of existence, not merely a conversation about experience: a naturalistic realism of independent existences that enter into and are transformed by human interactions with them.This perspective is shared by most Dewey scholars, including Sandra Rosenthal, Raymond Boisvert, and J. E. Tiles. At least until now. In a profound and provocative exploration of his early philosophy, John R. Shook, presents a compelling case that Dewey's reconstruction of metaphysics and epistemology is deeper than even Sleeper imagined. Dewey did not merely abandon idealism under the influence of William James, as most assume; he transformed it in a original way that, while wholly naturalistic, [End Page 312] is a fusion of idealism and realism that overcomes both the former's "mind-stuff" and the latter's "in-itself reality."Dewey began his philosophical odyssey with the searing desire to eradicate the dualisms of mind versus world, phenomenal versus noumenal, perceptual versus conceptual. Post-Hegelian idealists agreed that this division is ultimately reconciled in the "absolute," though they disagreed about whether the absolute is psychological or cosmological, social or supernatural, knowable or unknowable. From the very beginning, Shook argues, Dewey accepted the psychological path as sketched by James Ward, and also Edward Caird's claim that the absolute must be knowable in some sense. Intriguingly, the missing link between perception and conceptual awareness is Wilhelm Wundt's notion of volition: percepts are neither mechanically attached to concepts nor are they overlaid by Kantian "faculties of mind." Instead, a disruption of perceptual or noncognitive experience generates a desire for reconciliation that calls forth ideas that diagnose the problem and suggest ways to resolve it. Achieved solutions, in turn, forge a background of habitual dispositions that shape interpretations within the noncognitive realm.While still an idealist, then, Shook finds the essential elements of the "method of inquiry" that later anchored Dewey's instrumentalism and pragmatism. Prior to 1890, however, he still construed this as individual "mental activity," and the problem of its relation to God's Absolute Mind remained. Upon relinquishing the supernatural for the social, however, this final obstacle was eliminated. The dispositional background extends beyond the individual to the customs, traditions, and values of a culture—indeed, even the barest notions of "self" and "reality" are inconceivable without reference to such a background. This is Dewey's broad conception of "experience"—a humanistic naturalism with no trace of mind-stuff or subjectivism. In this sense Dewey is a realist, though his affirmation of things-themselves (including things we have not or may never actually discover) avoids the things-in-themselves that is the bane of metaphysical realism. To claim that things exist without an experiential background of how we may find them to exist is at best empty verbiage, and at worst hypnosis by the dervishes of dualism.Scrupulous in research, penetrating in detail, Shook's presentation is so faithful to Dewey that it will undoubtedly draw many of the same criticisms once hurled at the master. Though careful readers will be able to identify "experience" in its broadly social and functional sense, others will be confused by applications as diverse as "mental activity," "soul," "reality," "the history of the...

According to a familiar line of thinking, hallucination reveals that what we take to be direct experiences of the world are in fact mere appearances: appearances which give only mediate and unreliable testimony to reality. If we wish to secure knowledge of the world, we must transition to a different register, that of reason and judgment. In this classical analysis, non-normal perception functions to show the deficit of normal perception. Merleau-Ponty offers a strikingly different account of hallucination. Far from (...) inciting skeptical concerns, Merleau-Ponty’s analysis of hallucination in the Phenomenology of Perception in fact leads him to his first sustained account of perceptual faith. Perceptual faith, as our primary bond with the world, is at the heart of Merleau-Ponty’s response to skepticism, and it underlies both perception and hallucination. In this article, I show how this surprising analysis of hallucination is possible. (shrink)

Philosophers of perception often claim that usual perceptual experiences not only present particulars but also phenomenally present them as particulars. Nevertheless, despite the initial plausibility of this thesis, it is not clear what exactly it means to say that particularity is phenomenally presented. The paper aims to provide a deeper analysis of the claim that perceptual experiences phenomenally present objects as particulars. In doing so, I distinguish two theses regarding phenomenally presented particularity: Generic Particularity and Specific Particularity. According (...) to the first thesis, vision phenomenally presents particularity of objects, understood as a general characteristic that may be shared by many entities. The second thesis states that vision phenomenally presents particularity of objects, understood as an individual characteristic unique to each particular. I argue that, relying on knowledge concerning the functioning of perceptual mechanisms, vision does not phenomenally present generic particularity but it has certain abilities for presenting specific particularity.

Recent reconstructions of Heidegger's thoughts on ethics have a curious paradoxical feature. On the one hand, Heidegger, particularly in his Aristotle lectures of the 1920s, offers a view of practical reason on which Dasein has its “moral knowledge” in a fully perceptual, non-cognitive way. This generally sets Heidegger in opposition to the whole business of principled moral justification before the fact. On the other hand, the literature is peppered with what appear to be principled denunciations of immorality—particularly violations (...) of other Dasein—grounded in the analytic of Dasein. To see human life as having a stable ergon (“business” or “function”), with certain broad tasks to pursue and vices to avoid, is not necessarily counter-Aristotelian; on the contrary, it is basic to the kind of Aristotelianism Husserl pursued in his own lectures on ethics. Here I set Heidegger's Aristotelian model of practical reason amid the competing, though similar, Aristotelianisms of John McDowell and Husserl, which differ on their handling of the human ergon. I conclude that Heidegger's views on practical reason and moral knowledge certainly constrain and very much alter the business of moral justification, but they do not precisely rule it out. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Loopholes, Gaps, and What Is Held Fast”Lorraine Code (bio)Keywordsepistemology, incredulity, knowing other people, memory, testimonyNancy Potter’s compelling essay points to some of the limitations of the theoretical apparatus that the post-positivist empiricist epistemologies of the Anglo-American mainstream make available for evaluating experiential memory claims in general, and “false memory syndrome” in particular. The loopholes and gaps in these theories of knowledge push urgent questions about testimony, (...) trust, and the politics of knowledge into a prominent place on the agendas of successor epistemology projects. These politics are enacted in societies whose dominant rhetoric privileges eye-witness evidence and “knowledge by acquaintance” as sources of objective knowledge, yet whose practices of incredulity—of granting and withholding acknowledgement to testimonial knowledge claims—expose power-saturated structures of dominance and subordination and of arbitrarily uneven distributions of epistemic authority. 1For classical empiricists and their successors, perception, memory and testimony, hierarchically ordered with perception on top, count as the principal sources of empirical knowledge. This ordering maps the relative reliability of the processes, with perception ranking as most stable, reliable and secure, memory coming second on all of these scores, and testimony ranking a poor third, closer to opinion, hearsay and rumor than to the other more respectable sources. Perception, for these theories, is “immediate” in that it is direct, bare, uncontaminated either by the particularities of the perceiving subject or of the perceptual event: from its presumed (but contestable) immediacy, all the rest follows. Memory counts as perception at one remove, its reliability a function of the relative “vividness” of the perceptions it commemorates. The esteem commonly claimed for eye-witness testimony derives from this conception of memory, which is believed to ground the testimony because of its presumed proximity to “immediate” perception. Yet testimony, even in its restricted “knowledge by description” form, tends by contrast with perception and memory to be a shaky affair; and as the temporal distance between event and testimony increases, so knowledge of matters unavailable to direct observation fares less and less well in classical and post-positivist epistemologies. A distrust of testimony is at once understandable and odd, because so small a proportion both of communal and of “individual” knowledge indeed derives from first-hand observations and experiences: most of it comes from testimony in an extended sense that encompasses books, teachings, media reports, all of the sources and resources on which both secular and scholarly knowledge relies for much of its substance. This expanded construction of the term runs alongside [End Page 255] the first-personal “testimonial” sense that is more plainly operative in discussions of false memory syndrome which, despite its experiential source, is often likewise contested on grounds that discredit the “privileged access” status that these same epistemologies claim for experience at first hand.Epistemologists commonly assimilate testimony to monologic, observational knowledge, deriving its constitutive features from instances where a testimonial utterance can pose as another perception—this time an auditory one—in a personal set of knowledge-producing observations (e.g., Fricker 1987). Because the speaker may be lying or mistaken, the process may fail to transmit knowledge; but this failure can be read as a simple perceptual error or a misremembering. Such approaches ignore the constitutive function of an interpreter/listener in fostering or thwarting testimonial knowledge to subsume it, too, much under an observational model. Indeed, not only do they separate the knower from the known and the process of knowing, as Potter observes, they also separate the knower from other knowers to guard against their influencing (= contaminating) the knowledge-production process. Experiences where an interlocutor actually enables the production of knowledge do not figure in such analyses, 2 whose effect is to suggest that giving or hearing testimony invokes no more significant moral-political issues than do acts of perceiving tables and chairs: that hearing, like seeing, is believing. (Norman Malcolm’s analysis of memory, which Potter cites, would also underwrite such a view of testimony.) Yet standard empiricist and post-positivist epistemologies generate an inquisitorial model of eliciting testimony in which the more generalized “testimony” in the knowledge that people acquire from books, media reports, conversation, reference sources recedes from...

This article argues for an epistemology of music, stating that dealing with music can be considered as a process of knowledge acquisition. What really matters is not the representation of an ontological musical reality, but the generation of music knowledge as a tool for adaptation to the sonic world. Three major positions are brought together: the epistemological claims of Jean Piaget, the biological methodology of Jakob von Uexküll, and the constructivistic conceptions of Ernst von Glasersfeld, each ingstress the (...) role of the music user rather than the music. Dealing with music, in this view, is not a matter of representation, but a process of semiotization of the sonorous environment as the outcome of interactions with the sound. Hence the role of enactive cognition and perceptual-motor interaction with the sonic environment. What is considered a central issue is the way how listeners as subjects experience their own phenomenal world or Umwelt, and how they can make sense out of their sonic environment. Umwelt-research, therefore, is highly relevant for music education in stressing the role of the listener and his/her listening strategies. (shrink)

The paper discusses how abduction relates tochildren's early acquisition of words, and has three sections: (a) a brief description of Peirce's notion of abduction; (b) a developmentof a hypothesis for the content-related symbolic functioning of words; and (c)arguments that children's knowledge of such functioning involves two kinds of abduction. In (b), children's knowledge of the content-related symbolic functioning of words is argued to consist in practical knowledge ofhow to use words to direct attention to kindsof things. To (...) acquire such knowledge, a childmust form a practical causal hypothesis aboutthe kind of thing to which a word directs attention. I argue that forming such ahypothesis involves abduction. On the basis of empirical work of several developmentalists, I also argue that children use abduction notmerely in forming practical hypotheses for the functioning of their earliest words, but also in forming theoretical hypotheses about core(as contrasted perceptual and functional)features of natural and artificial kinds.

A central theme to be found in Dewey’s writings is his criticism of theories of knowledge proposed throughout the history of Western philosophy. None of the once familiar “isms,” whether it be a variant of empiricism, rationalism, or idealism, escaped Dewey’s scrutiny. And each in its turn proved to be unacceptable to Dewey, because it was found that each rested upon what Dewey referred to as “the philosophical fallacy,” namely “the conversion of eventual functions into antecedent existence,” or the (...) fallacy of selective emphasis. Basically, this fallacy amounted for Dewey to the emphasis of one aspect of scientific inquiry to the exclusion of the rest, and taking the features characteristic of that aspect as paradigmatic for the purpose of accounting for knowledge. Thus, for example, advocates of what Dewey called sensationalism, for whom knowledge was to be explicated in terms of an immediate acquaintance with a perceptual given, emphasized an aspect of scientific inquiry, viz., that inquiry is engaged in only when some given situation is problematic, without regard to the fact that even those features of a problematic situation, which are taken to be given and stable features for purposes of resolving the problem, are so taken only provisionally, depending upon whether the ensuing inquiry is successful in resolving the problem at hand.

What does cognitive neuroscience contribute to our philosophical understanding of concepts? Over the past several decades, brain researchers have employed the tools of cognitive neuroscience and neuropsychology to probe the structure and func­tion of the conceptual system. The results of this effort, which are often extremely surprising, raise more questions than they resolve. Brain research has invigorated age-old philosophical debates about the nature of concepts—such as whether concepts are perceptual representations—and generated new controversies about how conceptual knowledge is (...) organized. In this essay, I examine three debates in the neuroscience of conceptual knowledge: whether concepts are embodied or couched in amodal representations, whether conceptual knowledge is organized according to evolved categories, and whether the brain has multiple conceptual systems. My purpose is not to resolve these debates—rather, I intend to show how many of the proposed solutions fail to accommodate the diverse range of data emerging from cognitive neuroscience. I am therefore skeptical that brain data alone will resolve these issues, but remain optimistic that neuroscience has much to contribute to philosophical accounts of concepts. (shrink)

Chapter 1 First Person Access to Mental States. Mind Science and Subjective Qualities -/- Abstract. The philosophy of mind as we know it today starts with Ryle. What defines and at the same time differentiates it from the previous tradition of study on mind is the persuasion that any rigorous approach to mental phenomena must conform to the criteria of scientificity applied by the natural sciences, i.e. its investigations and results must be intersubjectively and publicly controllable. In Ryle’s view, philosophy (...) of mind needs to adopt an antimentalist stance to achieve this aim. Antimentalism not only definitively rejects the idea that mind is a substance separated from the body, it also denies that mental phenomena radically differ from physical phenomena by virtue of several unique features. Most problematically, mental phenomena have a conscious character (mental states are related to specific qualitative feelings) and are accessible only to the first-person (only the subject knows directly what s/he is experiencing inside his/her mind). Ryle takes a strong stance on antimentalism going so far as to maintain that an approach to mind which aims to meet the criteria of scientificity set by the natural sciences must avoid any reference to internal, unobservable mental states. In his view (which is considered a specifically philosophical version of psychological behaviorism and also addresses questions put forward in psychological research), mental states can be redescribed in terms of behavioral dispositions. In this chapter, we address the historical roots of the antimentalist view and analyze its relation to the later tradition of research on mind. We show that, compared to the antimentalist stance, functionalism and cognitivism take a step back when they maintain that direct reference to mental states is necessary since mental states cause and therefore explain human behavior. This step backwards is often interpreted as a return to mentalism. However, this is only partially true. Indeed, we suggest that these later traditions retain one important element of Ryle’s antimentalism, i.e. the idea that mental states must be uniquely identified using external and publicly observable criteria, while excluding any reference to introspection and those qualitative dimensions of a mental state, which are accessible only to the first-person. According to the perspective we put forward, this epistemological stance has continued to influence contemporary research on mind and current philosophical and psychological theories which both tend to exclude the subjective qualities of human experience from their accounts of how the mind works. The issue we raise here is whether this is legitimate or whether subjective qualities do play a role with respect to the way our mind works. The conclusion of this chapter anticipates the argument the book makes in in favor of this latter position, starting from a particular angle, i.e. the problem of how we categorize concepts related to our internal states. -/- Chapter 2 The Misleading Aspects of the Mind/Computer Analogy. The Grounding Problem and the Thorny Issue of Propriosensitive Information -/- Abstract. After the crisis of behaviorism, cognitivism and functionalism became the predominant models in the field of psychology and of philosophy, respectively. Their success is mainly due to the new key they use for interpreting mental processes: the mind/computer analogy. On the basis of this analogy, mental operations are seen as cognitive processes based on computations, i.e. on manipulations of abstract symbols which are in turn understood as informational unities (representations). This chapter identifies two main problems with this model. The first is how these symbols can relate to and communicate with perception and thus allow us to identify and classify what we perceive through the senses. Here we limit ourselves to presenting this issue in relation to the classical symbol grounding problem originally put forward by Harnad on the basis of Searle’s Chinese room argument. An attempt to address the problem raised here will be made in chap. 3. The second point we discuss in relation to the mind/computer analogy concerns the idea of information it fosters. Indeed, following this analogy, information is something available in the external world which can be captured by the senses and transmitted to the central system without being influenced or modified by the procedures of transmission. This perspective does not take into account that – unlike computers – in living beings information is acquired by means of the body. As Ulric Neisser has already pointed out, the body is itself an informational source that provides us with additional sensory experience that influences (modifies or complements) the information extracted from the external world by the senses. To develop this line of analysis and to determine exactly what information is provided by the body and how this might influence cognition, we examine Sherrington’s and Gibson’s positions. Moving on from their views, we qualify bodily information in terms of ‘proprioception’. We use ‘proprioception’ in a broad sense to describe any kind of experience we have of our internal states (including postural information as well as sensations related to the general state of the body and its parts). Following Damasio’s and Craig’s studies, we further elaborate this position, arguing that living beings are equipped with an internal propriosensitive monitoring system which maps all the changes that constantly occur in our body and that give us perceptual (‘proprioceptive’ or propriosensitive) information about what happens inside us. Moreover, relying on Goldie’s and Ratcliffe’s view, we show that emotional information can also be considered as a form of ‘proprioception’ which contributes to determining everything we perceive. This analysis leads us to the second main thesis of this book: ‘proprioception’ is a form of internal perception and it is an essential component of the sensory information we can access and use for all cognitive purposes. -/- Chapter 3 Semantic Competence from the Inside: Conceptual Architecture and Composition -/- Abstract. Concepts are essential constituents of thought: they are the instruments we use to categorize our experience, i.e. to classify things and group them together in homogeneous sets. Here we define concepts as the internal mental information (representations) that allows us, among other things, to master words in natural language. By analyzing the way in which individuals master word meanings we explore a number of hypotheses regarding the nature of concepts. Following Diego Marconi’s research, we differentiate between two kind of abilities that underpin lexical competence – so-called ‘referential’ and ‘inferential competence’ – and we suggest that, in order to support these abilities, concepts must also include two corresponding kinds of information, i.e. inferential and referential information. We point out that the most widely used and acknowledged theories of concepts do not make this distinction, instead broadly characterizing the information used for categorization in terms of propositionally described feature lists. However, we show that while feature lists can explain inferential competence, they do not account for referential competence. To address the issue of referential competence we examine Ray Jackendoff’s hypothesis that to account for the possibility of linking perceptual and conceptual information we need to assume the existence of a (visual) representation that encodes the geometric and topological properties of objects and bridges the gap between the percept and the concept. Furthermore, we analyze the extension of this work by Jesse Prinz who introduced the notion of a proxytype, a perceptual representation of a class of objects that incorporates structural and parametric information related to their appearance. However, as we point out, proxytypes can only explain the relationship between perception and concepts with respect to instances that can be perceived through the senses and that belong to the same class by virtue of their physical similarity. We suggest that this notion be extended to include larger conceptual classes. To accomplish this, we further develop Mark Johnson, George Lakoff and Jean Mandler’s idea of a schematic image and argue that conceptual representations include a perceptual schema. Perceptual schemata are non-linguistic, structured experiential gestalts (patterns or maps) that make use of information taken from all sensory modalities, including body perception. They accomplish a quasi-conceptual function: they allow us to recognize and to classify different instances. In this work, we hypothesize that perceptual schemata are an essential component of concepts, but not identical to them. Instead, we suggest that concepts include both perceptual and propositional information with perceptual schemata providing the ‘perceptual core concept’ that grounds related propositional information. -/- Chapter 4 In the Beginning There Were Categories. The Bodily Origin of Prelinguistic Categorical Organization: The Example of Folkbiological Taxonomies -/- Abstract. Studies of categorization in psychology and the cognitive sciences have made use of the notions of ‘category’ and ‘concept’ without precisely defining what is meant by either; in fact, often these terms have been used as synonyms, making it difficult to address specific issues related to conceptual development. This chapter begins by discussing the definitions of, as well as the distinctions between, ‘categories’ and ‘concepts’ in the classical philosophical tradition (Aristotle, Kant and Husserl). We introduce our view of categories with reference to Husserl. Categorization is defined as the way in which our experience is originally (pre-linguistically) organized in a passive and fully unconscious manner on the basis of universal structuring principles. Conceptualization is explained as a later process in which the earlier categorical macro-classes are further subdivided into more specific and detailed sets; this later process also relies on linguistic learning and exposure to culture. On the basis of Ray Jackendoff, Jean Mandler, George Lakoff and Mark Johnson’s work, we hypothesize that categorization is a two-step process that begins with the formation of homogeneous sets of entities partitioned into regions that describe the ontological boundaries of the objects that humans perceive (categories) and continues at a later stage with the development of more specific classifications (concepts). In this chapter, we mainly address three related issues: Why should we assume that there is categorical organization which precedes the development of a conceptual system? How do categories and concepts relate to each other? Shall we hypothesize that categories are innate or that they are formed before concepts on the basis of information and organizational structure available at a very early developmental stage? We show that categorical partitions are necessary for categorization and, following Mandler, that the general categories we form at an early age do not match our adult superordinate concepts. As for the third issue, we argue that there might be no need to assume that categories are innately present in the human mind, since their formation can be explained – at least in certain cases – by basic mechanisms that work on body (propriosensitive) information. This hypothesis will not be discussed in general, but in relation to a particularly relevant example of categorical partition, i.e. the folk-biological dichotomy between ANIMATE/INANIMATE. This is compared with other dichotomies that derive from it, but are not directly categorical such as LIVING/NON-LIVING and BIOLOGICAL/NON-BIOLOGICAL. -/- Chapter 5 Internal States: From Headache to Anger. Conceptualization and Semantic Mastery -/- Abstract. Here we ask if we can also apply the distinction between referential and inferential competence we introduced in Chapter 3 to words that do not refer to things that are perceived using the external senses, especially to words/concepts that denote bodily experiences (such as pain, thirst, hunger, etc.) or emotions. We introduce and discuss the hypothesis that – even though such words/concepts do not refer to intersubjectively identifiable entities in the external world – they do have a kind of referent that can be accessed via direct perception, more specifically ‘proprioception’, as we have defined it in terms of all propriosensitive information we can consciously access. In the first part of the chapter, we specifically consider terms denoting bodily experiences such as ‘pain’ or ‘hunger’ and argue that their referents are identified and classified from a first-personal point of view on the basis of four main characteristics: their specific intensity, their localization in the body, their co-occurrence with other signals and above all their specific qualitative sensations. Emotions are addressed in the second part of the chapter. We suggest that there is a continuity between bodily experiences and emotions. In particular, we argue for a perceptual theory of emotions in line with that proposed by James and Lange at the end of the 19th century and developed more recently by authors such as Damasio (see also chap. 2§5, §6). The hypothesis we put forward is that the referential information that supports the categorization of emotions and therefore also our mastery of terms referring to emotions consists in the perception (i.e. the ‘proprioception’) of those bodily states and changes in bodily states which constitute our emotional experience. In the context of this discussion we examine some objections to this line of reasoning that arise from a cognitivist perspective and following authors such as Oatley, Johnson-Laird and Frijda, we distinguish between basic emotions that can be identified and classified solely on the basis on how they feel and complex emotions whose identification and classification additionally depends on cognitive factors. To describe how emotions are identified and classified on the basis of how they feel, we rely on Marcel and Lambie’s distinction between an ‘emotion state’ and an ‘emotion experience’. Both notions indicate kinds of feelings that we consciously experience. However, they describe first-order and second order emotion awareness respectively. The emotion state is the feeling we have of the bodily states and changes that occur when we are experiencing an emotion, while the emotion experience is the fully developed and integrated emotion we both experience and are, with reflection, aware of experiencing. On the basis of this differentiation, we also show that the same characteristics that aid in the identification and classification of bodily experiences (specific qualitative sensations; somatic localization; specific intensity; presence/absence of specific concomitant sensations) can also be used for the identification and classification of emotions – at least basic emotions. In the last two sections of the chapter we present some clinical evidence on the semantic competence of people who suffer from Alexithymia and Autism Spectrum Disorder which supports the conclusions of our preceding analyses. -/- Chapter 6 The ‘Proprioceptive’ Component of Abstract Concepts -/- Abstract. In this chapter, we address the issue of whether the mastery of abstract words requires only inferential knowledge and thus, if the concepts that support the mastery of abstract words include only linguistic information. We start by differentiating the notions of ‘abstract’ and ‘general’ which are often erroneously confused. We then identify a strict definition of abstract, as contrasted with ‘concrete’, that applies to words or concepts whose referent cannot be experienced by the senses. We argue that abstract words/concepts would be better described as theoretical, because they are usually conceived as structured sets of inferential knowledge expressed linguistically; that is, as small theories. Pointing out parallels with Carnap’s analysis of this issue in philosophy of science, we hypothesize that words/concepts denoting non-observable entities are not all ‘equally theoretical’, because their link to sensory experience can be stronger or weaker. We revive the distinction, inspired by Quine, between theoretical and intertheoretical concepts/words. This distinction relies on the fact that the former – unlike the latter – retains a strong, although indirect, connection with perception. In Quine’s discussion, perception is understood uniquely in terms of observability, i.e. of external sensory experience. Here we argue, however, that bodily, ‘proprioceptive’ (i.e. propriosensitive) experience can also serve to referentially ground theoretical (i.e. abstract) concepts/words. We frame this issue using the example of the theoretical concept ‘freedom’ and Lakoff’s hypothesis that this concept is developed on the basis of bodily information. We contrast this with the example of ‘democracy’ which more closely resembles an intertheoretical concept/word. Furthermore, we show that one of the classical views put forward in psycholinguistic research to explain how abstract concepts are mentally represented – i.e. Paivio’s Dual Coding Theory – points in the same direction as our analysis. The same is true of Barsalou’s work suggesting that we use internal information to understand at least some abstract words. To sustain this position, we put forward two lines of evidence: the first comes from psycholinguistic studies while the second examines deficits of semantic competence exhibited by people with Autism Spectrum Disorder. On the basis of our analysis, we put forward a classification that distinguishes between different kinds of concreteness and different degrees of abstraction: concepts/words referring to body experiences and basic emotions are described as analogous to concrete concepts/words because they are grounded in perceptual (i.e. propriosensitive) experience, while abstract concepts/words are considered more or less abstract depending on whether they are intratheoretical (and rely entirely on inferential information) or theoretical (and are partially grounded in perceptual – or more often in propriosensitive perceptual – information). In the last section of the chapter we consider two scales that have been used in psycholinguistic research to measure the degree of concreteness vs. abstractness of words and we show that – used conjointly – they can provide a measure of the internal vs. external grounding of specific words.

Evolutionary epistemology has experienced a continuous rise over the last decades. Important new theoretical considerations and novel empirical findings have been integrated into the existing framework. In this paper, I would like to suggest three lines of research that I believe will significantly contribute to further advance EE: ontogenetic considerations, key ideas from cognitive biology, and the framework of the Extended Evolutionary Synthesis. EE, in particular the program of the evolution of epistemological mechanisms, seeks to provide a phylogenetic account of (...) the generation of cognitive processes underlying knowledge creation. Traditionally, EE and EEM have been oriented towards an account of evolutionary theory that mainly drew from the tenets of the Modern Synthesis. The Modern Synthesis largely dismisses ontogenetic processes and considers them irrelevant for evolutionary explanations. If anything, the role of development in evolution is believed to be that of a constraint. There is, however, ample evidence for a tight intertwinement of developmental and evolutionary processes. Organisms employ their cognitive apparatus to interact with the environment in order to achieve a fully functioning perceptual and cognitive nervous system. Also, ontogeny provides generative potentials to enable variations that natural selection can act upon. EEM’s agenda may, therefore, strongly benefit from bringing together ontogenetic and phylogenetic approaches. To grapple with this challenge, an alternative vision of the evolutionary theory termed Extended Evolutionary Synthesis could be used. This extended evolutionary theory explores relationships between the processes of individual development and phenotypic change during evolution and can provide a more suitable framework for EEM to draw from. In recent years, cognitive biology has gained momentum as an independent research field. Cognitive biology builds on the concepts of EEM and understands knowledge as a biogenic phenomenon. Its main objective is also the formulation of substantiated interrelations between cognition and evolution but it focuses on cognitive functionality at all levels of biological organization. It thus employs a “vertical” approach that encompasses nested hierarchies which span from single molecules, cells, and tissues to the organismal level, communities, and societies. In contrast to cognitive biology, EEM is here understood to adopt a “horizontal” approach that focuses on phylogenetic explanations of cognition and knowledge acquisition. Linking EEM with the key ideas of cognitive biology could make EEM’s research program stronger as it can more easily accommodate phylogenetic and ontogenetic questions within a hierarchical, multilevel perspective. This is of particular importance for a more comprehensive account of cognition since living systems are subject to context-dependent causal influences from different organizational levels. In addition to EEM, there is a second program of EE. This program has been labeled evolutionary epistemology of theories and understands the increase in human knowledge, such as scientific theories, as naturalistic accounts of evolution. Both, EEM and EET initially drew from the core concepts of the Modern Synthesis. Several scholars have severely criticized the analogies made between EET and the Neo-Darwinian key processes of evolution. In particular processes of random mutation, the rate of variation, natural selection as the unique driving force, and the adaptationist agenda are believed to reveal disanalogies. In contrast to the Modern Synthesis, the Extended Evolutionary Synthesis not only recognizes developmental processes but also ecological interactions and systems dynamics as well as social and cultural evolutionary reciprocity as important evolutionary processes. Concepts of the Extended Evolutionary Synthesis are therefore expected to be more fruitful for re-conceptualizing parallels between scientific theorizing and biological evolution. (shrink)

I know, for the most part, what I think, want, and intend, and what my sensations are. In addition, I know a great deal about the world around me. I also sometimes know what goes on in other people's minds. Each of these three kinds of empirical knowledge has its distinctive characteristics. What I know about the contents of my own mind I generally know without investigation or appeal to evidence. There are exceptions, but the primacy of unmediated self- (...) class='Hi'>knowledge is attested by the fact that we distrust the exceptions until they can be reconciled with the unmediated. My knowledge of the world outside of myself, on the other hand, depends on the functioning of my sense organs, and this causal dependence on the senses makes my beliefs about the world of nature open to a sort of uncertainty that arises only rarely in the case of beliefs about my own states of mind. Many of my simple perceptions of what is going on in the world are not based on further evidence; my perceptual beliefs are simply caused directly by the events and objects around me. But my knowledge of the propositional contents of other minds is never immediate in this sense; I would have no access to what others think and value if I could not note their behaviour. (shrink)

Discussion continues here of a theory I have previously described as being an equivocal remembrance theory of inner awareness, the direct appre-hension of one’s own mental-occurrence instances . O’Shaughnessy claims that we acquire knowledge of each of our experiences as it occurs, yet any occurrent cognitive awareness of it that we may have comes later and is mediated by memory. Thus, acquiring knowledge of an experience firsthand is automatic and silent, not a matter of experientially apprehending the experience. (...) Although O’Shaughnessy does hold that every experience has itself as an object, this is not a matter of a cognitive self-apprehension . O’Shaughnessy’s grounds for his proposal of a nonexperiential acquisition of knowledge of one’s experiences amounts to the claim that to hold otherwise would imply an infinite regress of experiences, for the experience by which we would know of an experience would be itself the object of experience, etc. I argue that neither an appendage theory nor an intrinsic theory of inner awareness, both of which are experiential, sets an experiential regress going. Then, I argue that something experiential would seem to be essential to acquiring firsthand knowledge of one’s experiences according to O’Shaughnessy’s own account of environmental perception. At its core is the thesis that the basic perceptual experience, the primary component of a perception, is a nonconceptual and noncognitive noticing of present sensations produced by environmental items. This first component evokes a second, cognitive component of the experience that is a recognitional awareness of the first component. Only in this way could perception perform its cognitive function, according to the theory, which is to yield knowledge of sensations and their causes in the environment. But the recognitional awareness, the “interpretative” component, clearly is experiential and an inner awareness. Moreover, O’Shaughnessy does not appear to view this component as resulting in an infinite number of inner awarenesses because implicitly he considers it, perhaps, to be intrinsic to the perceptual experience.

The function of Metaphysics is to furnish an intelligible and significant perspective. The tendency of recent speculation is to abstain from the attempt to give a total or absolute perspective of the world as a unit—there is some question as to whether we can think of the world as a whole—but rather to understand the objects about us, to bring values, formerly located in a transcendental realm, into life and conduct here and now, and to broaden our understanding and interests (...) to included related activities and other communities. To make our perspective within a single science intelligible it is necessary, as Professor Miller has demonstrated, to fill in the gaps between perceptual objects with inexperienceable “interphenomena” and to employ methodological concepts and principles derived by abstraction and inference. Then again, each of the special sciences selects certain aspects of the general perspective for intensive research leaving gaps between the sciences to be filled in by integrating concepts. Finally, values emerge at the various levels, and these need to be related to the conditions out of which they arise and to the fields of applied knowledge in which they function. (shrink)

Feldman and Goldsmith sought an evolutionary explanation of the child prodigy phenomenon. Following in this vein, a theory involving the evolution and development of the collaboration of working memory and the cognitive functions of the cerebellum is presented with commentary on Edmunds and Noel’s report on a child’s literary precocity. It is argued that the evolution of working memory and the cerebellum within the increasing rule-governed complexity of culture may have produced the child prodigy within agricultural villages as early as (...) 10,000 years ago, in child prodigies, heightened emotional–attentional control in the central executive of working memory and modeled in the cerebellum is acquired in infancy through perceptual analysis , and this heightened emotional–attentional control begins in visuospatial processing, links visuospatial and language processing in working memory , and initiates and accelerates a positive feedback loop with the cerebellum in a specific knowledge domain. It is concluded that the working memory– cerebellar approach provides an evolutionary and developmental explanation of the child prodigy and strongly supports Edmunds and Noel’s visuospatial–high verbal ability explanation.

Perception purports to help you gain knowledge of the world even if the world is not the way you expected it to be. Perception also purports to be an independent tribunal against which you can test your beliefs. It is natural to think that in order to serve these and other central functions, perceptual representations must not causally depend on your prior beliefs and expectations. In this paper, I clarify and then argue against the natural thought above. All (...) perceptual systems must solve an under-determination problem: the sensory data they receive could be caused by indefinitely many arrangements of distal objects and properties. Using a Bayesian approach to perceptual processing, I argue that in order to solve the under-determination problem, perceptual capacities must rely on prior beliefs or expectations of some kind. I then argue that perceptual states or processes can help ground knowledge of the world whether the ‘beliefs’ necessary for perceptual processing are encoded as sub-personal states within a perceptual system or cognitive states, such as person-level beliefs. My argument has two main parts. First, I give a preliminary argument that cognitive influence on perception can be appropriate, and I respond to three lines of objection. Second, I argue that cognitively influenced perceptual states can be instances of seeing that p, which makes the relevant states well suited to help ground knowledge that p. I conclude that a cognitively penetrated perceptual state or process can help ground knowledge under some circumstances. (shrink)

Abstract Since their inception, distributional models of semantics have been criticized as inadequate cognitive theories of human semantic learning and representation. A principal challenge is that the representations derived by distributional models are purely symbolic and are not grounded in perception and action; this challenge has led many to favor feature-based models of semantic representation. We argue that the amount of perceptual and other semantic information that can be learned from purely distributional statistics has been underappreciated. We compare the (...) representations of three feature-based and nine distributional models using a semantic clustering task. Several distributional models demonstrated semantic clustering comparable with clustering-based on feature-based representations. Furthermore, when trained on child-directed speech, the same distributional models perform as well as sensorimotor-based feature representations of children’s lexical semantic knowledge. These results suggest that, to a large extent, information relevant for extracting semantic categories is redundantly coded in perceptual and linguistic experience. Detailed analyses of the semantic clusters of the feature-based and distributional models also reveal that the models make use of complementary cues to semantic organization from the two data streams. Rather than conceptualizing feature-based and distributional models as competing theories, we argue that future focus should be on understanding the cognitive mechanisms humans use to integrate the two sources.

In this double-volume work, a great modern philosopher propounds a system of thought in which Einstein's theory of relativity represents only the latest (albeit the most radical) fulfillment of the motives inherent to mathematics and the physical sciences. In the course of its exposition, it touches upon such topics as the concept of number, space and time, geometry, and energy; Euclidean and non-Euclidean geometry; traditional logic and scientific method; mechanism and motion; Mayer's methodology of natural science; Richter's definite proportions; relational (...) concepts and the activity of the ego; Einstein's relativity and "reality"; and the philosophical concept of truth and its role in relativity theory. 1923 edition.
