Perception-Based Theories of Concepts

Research on concepts has concentrated on the way people apply concepts online, when presented with a stimulus. Just as important, however, is the use of concepts offline, when planning what to do or thinking about what is the case. There is strong evidence that inferences driven by conceptual thought draw heavily on special-purpose resources: sensory, motoric, affective, and evaluative. At the same time, concepts afford general-purpose recombination and support domain-general reasoning processes—phenomena that have long been the focus of philosophers. There (...) is a growing consensus that a theory of concepts must encompass both kinds of process. This book shows how concepts are able to act as an interface between general-purpose reasoning and special-purpose systems. Concept-driven thinking can take advantage of the complementary costs and benefits of each. The book lays out an empirically-based account of the different ways in which thinking with concepts takes us to new conclusions and underpins planning, decision-making, and action. It also spells out three useful implications of the account. First, it allows us to reconstruct the commonplace idea that thinking draws on the meaning of a concept. Second, it offers an insight into how human cognition avoids the frame problem and the complementary, less discussed, ‘if-then problem’ for nested processing dispositions. Third, it shows that metacognition can apply to concepts and concept-driven thinking in various ways. The framework developed in the book elucidates what it is that makes concept-driven thinking an especially powerful cognitive resource. (shrink)

I present a reading of Marx’s critique of what he terms ‘intuitional materialism’, an expression which suggests a close link to Kant’s account of intuition. On my account, Marx advocates a view of sensibility as active, whereas Kant’s account of sensibility has often been interpreted as passive. In so doing, I claim that Marx offers an implicit critique of the conventional distinction between the ‘higher’ and ‘lower’ faculties, encompassing Wilfrid Sellars’ attack on the myth of the given. Marx claims that (...) limiting the contribution of cognition to the abstraction of particulars into concepts is a symptom of alienation under capitalism, while unalienation consists in the aesthetic attunement of sensible activity to the particularity of experience. This view is importantly related, I claim, to the cue Marx and Engels took from Darwin in reconceiving biological science, including the study of human material life, as dynamic and organic rather than mechanical.

On the traditional relationalist conception of singular thought, a thought has singular content when it is based on an ‘information relation’ to its object. Recent work rejects relationalism and suggests singular thoughts are distinguished from descriptive thoughts by their inferential role: only thoughts with singular content can be employed in ‘direct’ inferences, or inferences that ‘trade on identity’. Firstly this view is insufficiently clear, because it conflates two distinct ideas—one about a kind of inference, the other a kind of process (...) that grounds inferences—under the title, ‘trading on identity’. Secondly, this leaves us without a notion that can be used as an alternative to relationalism about singular thought. The first notion is no more applicable to singular than to descriptive thought. The second may help us better understand singular thought, but does so, not by replacing the view that singular thoughts are information-based, but by helping us understand the nature of information-based thought.

The expanding social role and continued development of artificial intelligence (AI) needs theological investigation of its anthropological and moral potential. A pragmatic theological anthropology adapted for AI can characterize moral AI as experiencing its natural, social, and moral world through interpretations of its external reality as well as its self-reckoning. Systems theory can further structure insights into an AI social self that conceptualizes itself within Ignacio Ellacuria’s historical reality and its moral norms through Thomistic ideogenesis. This enables a conceptualization process (...) capable of carrying moral weight and grounded in reality; structures the experience of an AI emergent self into multiple levels of interpretation; and drives a multi-level systems architecture for moral AI. Modeling AI’s interpretive experience and self-reckoning as a causal, sociotechnical, and moral actor can help moral AI identify conflicts between its normative values and develop the practical wisdom (phronesis) needed to apply its general moral models.

Event concepts are unstructured atomic concepts that apply to event types. A paradigm example of such an event type would be that of diaper changing, and so a putative example of an atomic event concept would be DADDY'S-CHANGING-MY-DIAPER.1 I will defend two claims about such concepts. First, the conceptual claim that it is in principle possible to possess a concept such as DADDY'S-CHANGING-MY-DIAPER without possessing the concept DIAPER. Second, the empirical claim that we actually possess such concepts and that they (...) play an important role in our cognitive lives. The argument for the empirical claim has the form of an inference to the best explanation and is aimed at those who are already willing to attribute concepts and beliefs to infants and nonhuman animals. Many animals and prelinguistic infants seem capable of re-identifying event-types in the world, and they seem to store information about things happening at particular times and places. My account offers a plausible model of how such organisms are able to do this without attributing linguistically structured mental states to them. And although language allows adults to form linguistically structured mental representations of the world, there is no good reason to think that such structured representations necessarily replace the unstructured ones. There is also no good reason for a philosopher who is willing to explain the behavior of an organism by appealing to atomic concepts of individuals or kinds to not use a similar form of explanation when explaining the organism's capacity to recognize events. -/- We can form empirical concepts of individuals, kinds, properties, event-types, and states of affairs, among other things, and I assume that such concepts function like what François Recanati calls ‘mental files’ or what Ruth Millikan calls ‘substance concepts’ (Recanati 2012; Millikan 1999, 2000, 2017). To possess such a concept one must have a reliable capacity to re-identify the object in question, but this capacity of re-identification does not fix the reference of the concept. Such concepts allow us to collect and utilize useful information about things that we re-encounter in our environment. We can distinguish between a perception-action system and a perception-belief system, and I will argue that empirical concepts, including atomic event concepts, can play a role in both systems. The perception-action system involves the application of concepts in the service of (often skilled) action. We can think of the concept as a mental file containing motor-plans that can be activated once the individual recognizes that they are in a certain situation. In this way, recognizing something (whether an object or an event) as a token of a type, plays a role in guiding immediate action. The perception-belief system, in contrast, allows for the formation of beliefs that can play a role in deliberation and planning and in the formation of expectations. I distinguish between two particular types of belief which I call where-beliefs and when-beliefs, and I argue that we can model the formation of such perceptual beliefs in nonlinguistic animals and human infants in terms of the formation of a link between an empirical concept and a position on a cognitive map. According to the account offered, seemingly complex beliefs, such as a baby's belief that Daddy changed her diaper in the kitchen earlier, will not be linguistically structured. If we think that prelinguistic infants possess such concepts and are able to form such beliefs, it is likely that adults do too. The ability to form such beliefs does not require the capacity for public language, and we can model them in nonlinguistic terms; thus, we have no good reason to think of such beliefs as propositional attitudes. Of course, we can use sentences to refer to such beliefs, and thus it is possible to think of such beliefs as somehow relations to propositions. But it is not clear to me what is gained by this as we have a perfectly good way to think about the structure of such beliefs that does not involve any appeal to language. (shrink)

Several different quantum gravity research programmes suggest, for various reasons, that spacetime is not part of the fundamental ontology of physics. This gives rise to the problem of empirical coherence: if fundamental physical entities do not occupy spacetime or instantiate spatiotemporal properties, how can fundamental theories concerning those entities be justified by observation of spatiotemporally located things like meters, pointers and dials? I frame the problem of empirical coherence in terms of entailment: how could a non-spatiotemporal fundamental theory entail spatiotemporal (...) evidence propositions? Solutions to this puzzle can be classified as realist or antirealist, depending on whether or not they posit a non-fundamental spacetime structure grounded in or caused by the fundamental structure. These approaches place different constraints on our everyday concepts of space and time. Applying lessons from the philosophy of mind, I argue that only realism is both conceptually plausible and suitable for addressing the problem at hand. I suggest a role functionalist version of realism, which is consistent with both grounding and causation, and according to which our everyday concepts reveal something of the true nature of emergent spacetime.

This essay aims to provide conceptual tools for the understanding of Wittgenstein’s theory of color as a grammar problem instead of a phenomenological or purely scientific one. From an introduction of his understanding of meaning in his early and late life, his notion of grammar will be analyzed to understand his rebuttal of scientific and phenomenological discourse as a proper means for dealing with the problem of color through his critique of Goethe. Then Wittgenstein’s take on color will become clear (...) as his sympathy for Runge, the painter that Goethe criticizes, is analyzed to understand color as a language-game regarding kinds of colors as numbers and geometrical figures, in that grammar rather than experience is used to acknowledge them.

Whereas Charles Peirce’s pragmatist account of truth has been much discussed, his theory of perception still offers a rich mine of insights. Peirce presented a ‘two-ply’ view of perception, which combines an entirely precognitive ‘percept’ with a ‘perceptual judgment’ that is located in the space of reasons. Having previously argued that Peirce outdoes Robert Brandom in achieving a hyper-inferentialism (“Making it Explicit and Clear”, APQ, 2008), I now wish to examine his philosophy in the light of inferentialism’s ‘original fount’ – (...) Wilfrid Sellars. Does Peirce’s percept commit him to the Myth of the Given? I argue that it does not, because although the percept is understood as nonepistemic, it is not understood to justify the perceptual judgment. Rather, the perceptual judgement indexes the percept. I explain this original view, then argue that Peirce and Sellars actually have a great deal in common in their rare diachronically mediated yet at the same time direct perceptual realism, and the ‘critical commonsensist’ epistemology to which it gives rise.

The purpose of this paper is to defend Langsam’s Theory of Appearing (TA) against Djukic et al’s critique. In strengthening Langsam’s defense of TA, I adopt some of Le Morvan's arguments in defending Direct Realism. TA states that experiences are relations between material object and mind, and that phenomenal features are appearances of relations held between material objects and mind. Djukic objects to TA on three grounds of Hallucination, Causal Principle (CP), and Time-Gap: First, Djukic objects to TA on the (...) ground that perception and hallucinations are phenomenally indistinguishable, thus phenomenal features (or properties) instantiated in perception may not be relations either, and thus TA could fail. In defending TA, Langsam argues that indistinguishability does not entail that perception and hallucination instantiate the same appearance. Moreover, disjunctivist conception of experience supports TA in that phenomenal features are either a relation between a material object and mind, or it is something else (as in cases of hallucination). I aim to show that sense-data (or like) theories of perception, that Djukic favors as being superior, would fail Djukic's own scrutiny in cases of hallucination in addition to being against common-sense. Second objection is that perception and hallucination must have the same-cause because they are indistinguishable, and also CP requires that same-causes to produce the same-effects. But hallucination and perception are different experiences, and hence TA fails CP. Responding to CP objection, “same-cause same-effect” only applies to intrinsic changes and intrinsic changes are changes in intrinsic properties and relations between intrinsic properties. Third, TA is opposed because for a given Time-Gap we cannot experience objects as they are (were) at the time of our perception. TA defeats this objection because it does not claim that “we can now (experience) the no-longer existent object as it is now, but only that we can now (experience) the once-existent object as it used to be. Fourth, to further strengthen TA, I will raise objections to TA including from the vantage point of Durability, Perceptual Relativity, Illusion, and Partial Perception arguments, and respond to such objections accordingly. To explicate TA, I argue from the vantage points of common sense, realistic physical biological considerations, and non-miraculous expectations from any theory of perception, including from TA.

La distinción entre contenidos conceptuales y no-conceptuales tiene claras repercusiones en el modo en que el hombre configura su mundo, así como en la posibilidad de atribuir pensamiento, en sentido estricto, a sistemas y organismos no humanos. Con el fin de clarificar dicha distinción, en el presente trabajo se plantea una noción básica de estado mental y, especialmente, una definición clara de lo que es un concepto y las características esenciales de los estados en que estos aparecen. Lo que se (...) sostiene al final es que hay buenas y suficientes razones para hablar de contenidos conceptuales y contenidos no-conceptuales, en lugar de hacerlo de contenidos más o menos conceptuales. En otras palabras, que hay una distinción de tipo, y no de grado, entre unos y otros contenidos. (shrink)

Philosophers have often claimed that general ideas or representations have their origin in abstraction, but it remains unclear exactly what abstraction as a psychological process consists in. We argue that the Lockean aspiration of using abstraction to explain the origins of all general representations cannot work and that at least some general representations have to be innate. We then offer an explicit framework for understanding abstraction, one that treats abstraction as a computational process that operates over an innate quality space (...) of fine-grained general representations. We argue that this framework has important philosophical implications for the nativism-empiricism dispute, for questions about the acquisition of unstructured representations, and for questions about the relation between human and animal minds.

In this paper we advocate the thesis that qualia are tropes (or qualitons), and not (universal) properties. The main advantage of the thesis is that we can accept both the Wittgensteinian and Sellarsian assault on the given and the claim that only subjective and private states can do justice to the qualitative character of experience. We hint that if we take qualia to be tropes, we dissolve the problem of inverted qualia. We develop an account of sensory concept acquisition that (...) takes the presence of qualia as an enabling condition for learning. We argue that qualia taken to be qualitons are part of our mechanism of sensory concept acquisition. (shrink)

Imagism about Phenomenal Thought is (roughly) the view that there is some concept *Q* (for some sensory quality Q) that we can employ only while we experience the quality Q. I believe this view is theoretically significant, is or can be made intuitively appealing, and is explicitly or implicitly accepted by many contemporary philosophers However, there is no good reason to accept it. Or so I argue.

Harold Brown has written an ambitious work, which traces the formation of concepts in individuals and cultures, examines case studies of concepts in calculus, mathematics, biology and related fields, summarises important philosophical works on the theory of concepts, and seeks to reconcile scientific realism with conceptual change. Brown considers himself a scientific realist but concedes that this very label is one that depends on a long history of concepts that came before, and may indeed be superseded as conceptual change continues. (...) Yet, concepts are not strictly relative to their contexts. ‘‘The usual claim is that truth is relative – period; and this claim assumes a non-relativized truth-concept’’ (p. 309). Crucial to his goal of developing a theory of concepts is how Brown reconciles conceptual change with objectivity. (shrink)

Embodied Cognition is the kind of view that is all trees, no forest. Mounting experimental evidence gives it momentum in fleshing out the theoretical problems inherent in Cognitivists’ separation of mind and body. But the more its proponents compile such evidence, the more the fundamental concepts of Embodied Cognition remain in the dark. This conundrum is nicely exemplified by Pecher and Zwaan’s book, Grounding Cognition, which is a programmatic attempt to rally together an array of empirical results and linguistic data, (...) and its successes in this endeavor nicely epitomize current directions among the various research provinces of Embodied Cognition. The untoward drawback, however, is that such successes are symptomatic of the growing imbalance between experimental progress and theoretical interrogation. In particular, one of the theoretical cornerstones of Embodied Cognition —namely, the very concept of grounding under investigation here—continues to go unilluminated. Hence, the advent of this volume indicates that—now more than ever—the concept of grounding is in dire need of some plain old-fashioned conceptual analysis. In that sense, Embodied Cognition is grounded until further notice. (shrink)

This paper argues that perception is a mode of engagement with individuals and their determinate properties. Perceptual content involves determinate properties in a way that relies on our conceptual capacities no less than on the properties. The “richness” of perceptual experience is explained as a distinctive individual and property involving content. This position is developed in three steps: (i) novel phenomenological description of lived experience; (ii) detailed reconstruction of Gareth Evans’ proposal that we are capable of genuinely singular thought that (...) involves individuals under modes of presentation; (iii) re-consideration of the re-identification condition on conceptual contents.

Given the fundamental role that concepts play in theories of cognition, philosophers and cognitive scientists have a common interest in concepts. Nonetheless, there is a great deal of controversy regarding what kinds of things concepts are, how they are structured, and how they are acquired. This chapter offers a detailed high-level overview and critical evaluation of the main theories of concepts and their motivations. Taking into account the various challenges that each theory faces, the chapter also presents a novel approach (...) to concepts that is organized around two ideas. The first is a pluralistic view of differing types of conceptual structure. The second is a model that treats concepts as atomic representations that are linked to various types of conceptual structures. (shrink)

Jerry Fodor has argued that concept acquisition cannot be a psychological or “rational-causal” process, but can only be a “brute-causal” process of acquisition. This position generates the “doorknob  DOORKNOB” problem: why are concepts typically acquired on the basis of experience with items in their extensions? I argue that Fodor’s taxonomy of causal processes needs supplementation, and characterize a third type: what I call “intelligible-causal processes.” Armed with this new category I present what I regard as a better response than (...) Fodor’s to the doorknob  DOORKNOB problem. (shrink)
