Social ontology is the study of the nature and properties of the social world. It is concerned with analyzing the various entities in the world that arise from social interaction. -/- A prominent topic in social ontology is the analysis of social groups. Do social groups exist at all? If so, what sorts of entities are they, and how are they created? Is a social group distinct from the collection of people who are its members, and if so, how is (...) it different? What sorts of properties do social groups have? Can they have beliefs or intentions? Can they perform actions? And if so, what does it take for a group to believe, intend, or act? -/- Other entities investigated in social ontology include money, corporations, institutions, property, social classes, races, genders, artifacts, artworks, language, and law. It is difficult to delineate a precise scope for the field (see section 2.1). In general, though, the entities explored in social ontology largely overlap with those that social scientists work on. A good deal of the work in social ontology takes place within the social sciences (see sections 5.1–5.8). -/- Social ontology also addresses more basic questions about the nature of the social world. One set of questions pertains to the constituents, or building blocks, of social things in general. For instance, some theories argue that social entities are built out of the psychological states of individual people, while others argue that they are built out of actions, and yet others that they are built out of practices. Still other theories deny that a distinction can even be made between the social and the non-social. -/- A different set of questions pertains to how social categories are constructed or set up. Are social categories and kinds produced by our attitudes? By our language? Are they produced by causal patterns? And is there just one way social categories are set up, or are there many varieties of social construction? -/- The term ‘social ontology’ has only come into wide currency in recent years, but the nature of the social has been a topic of inquiry since ancient Greece. As a whole, the field can be understood as a branch of metaphysics, the general inquiry into the nature of entities. (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.

Radical constructivism has had a major influence on present-day education, especially in the teaching of science and mathematics. The article provides an epistemological profile of constructivism and considers its strengths and weaknesses from the standpoint of its educational implications. It is argued that there are two central problems with constructivism: anti-realism and individualism which, in turn, lead to difficulties associated with idealism and relativism which, together, prove fatal for the theory.

An introductory overview of the main issues in the epistemology of perception.

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

Berkeley holds that vision, in isolation, presents only color and light. He also claims that typical perceivers experience distance, figure, magnitude, and situation visually. The question posed in New Theory is how we perceive by sight spatial features that are not, strictly speaking, visible. Berkeley’s answer is “that the proper objects of vision constitute an universal language of the Author of nature.” For typical humans, this language of vision comes naturally. Berkeley identifies two sorts of objects of vision: primary (light (...) and colors) and secondary (distance, figure, magnitude, and situation). Berkeley also appeals to a third class of a different sort: visible figure, magnitude, and situation, constituting the vocabulary of the language of vision. By considering two perceivers who lack this vocabulary we may better understand this third category and the difference between those who must learn the language of vision and those for whom it is a natural endowment.

Philosophy, as it is understood and practiced in the West, is and has been generally considered to be the search for truth. But even if philosophy is the search for truth, it does not automatically follow that those who are identified as ‘philosophers’ are themselves actually engaged in that search. And indeed, in this paper I argue that many philosophers have in fact not been genuinely engaged in the search for truth (in other words, many philosophers have not been doing (...) philosophy) and as such much of what passes for philosophy is in fact not really philosophy at all.

How is the burden of proof to be distributed among individuals who are involved in resolving a particular issue? Under what conditions should the burden of proof be distributed unevenly? We distinguish attitudinal from dialectical burdens and argue that these questions should be answered differently, depending on which is in play. One has an attitudinal burden with respect to some proposition when one is required to possess sufficient evidence for it. One has a dialectical burden with respect to some proposition (...) when one is required to provide supporting arguments for it as part of a deliberative process. We show that the attitudinal burden with respect to certain propositions is unevenly distributed in some deliberative contexts, but in all of these contexts, establishing the degree of support for the proposition is merely a means to some other deliberative end, such as action guidance, or persuasion. By contrast, uneven distributions of the dialectical burden regularly further the aims of deliberation, even in contexts where the quest for truth is the sole deliberative aim, rather than merely a means to some different deliberative end. We argue that our distinction between these two burdens resolves puzzles about unevenness that have been raised in the literature. (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.

We are prone to gross error, even in favorable circumstances of extended reflection, about our own ongoing conscious experience, our current phenomenology. Even in this apparently privileged domain, our self-knowledge is faulty and untrustworthy. We are not simply fallible at the margins but broadly inept. Examples highlighted in this essay include: emotional experience (for example, is it entirely bodily; does joy have a common, distinctive phenomenological core?), peripheral vision (how broad and stable is the region of visual clarity?), and the (...) phenomenology of thought (does it have a distinctive phenomenology, beyond just imagery and feelings?). Cartesian skeptical scenarios undermine knowledge of ongoing conscious experience as well as knowledge of the outside world. Infallible judgments about ongoing mental states are simply banal cases of self-fulfillment. Philosophical foundationalism supposing that we infer an external world from secure knowledge of our own consciousness is almost exactly backward. (shrink)

The philosophical method of conceptual analysis has been criticised on the grounds that empirical psychological research has cast severe doubt on whether concepts exist in the form traditionally assumed, and that conceptual analysis therefore is doomed. This objection may be termed the Charge from Psychology. After a brief characterisation of conceptual analysis, I discuss the Charge from Psychology and argue that it is misdirected.

In Book I, Part I, Section VII of the Treatise, Hume sets out to settle, once and for all, the early modern controversy over abstract ideas. In order to do so, he tries to accomplish two tasks: (1) he attempts to defend an exemplar-based theory of general language and thought, and (2) he sets out to refute the rival abstraction-based account. This paper examines the successes and failures of these two projects. I argue that Hume manages to articulate a plausible (...) theory of general ideas; indeed, a version of his account has defenders in contemporary cognitive science. But Hume fails to refute the abstraction-based account, and as a result, the early modern controversy ends in a stalemate, with both sides able to explain how we manage to speak and think in general terms. Although Hume fails to settle the controversy, he nevertheless advances it to a point from which we have yet to progress: the contemporary debate over abstract ideas in cognitive science has stalled on precisely this point.

The target article is an attempt to make some progress on the problem of color realism. Are objects colored? And what is the nature of the color properties? We defend the view that physical objects (for instance, tomatoes, radishes, and rubies) are colored, and that colors are physical properties, specifically types of reflectance. This is probably a minority opinion, at least among color scientists. Textbooks frequently claim that physical objects are not colored, and that the colors are "subjective" or "in (...) the mind." The article has two other purposes: first, to introduce an interdisciplinary audience to some distinctively philosophical tools that are useful in tackling the problem of color realism and, second, to clarify the various positions and central arguments in the debate.

In the Queries to the Latin version of the Opticks Newton claims that space is God’s sensorium. Although these passages are well-known, few commentators have offered interpretations of what Newton might have meant by these cryptic remarks. As is well known, Leibniz was quick to pounce on these passages as evidence that Newton held untenable or nonsensical views in metaphysics and theology. Subsequent commentators have largely agreed. This paper has two goals. The first is to offer a clear interpretation of (...) Newton’s claim about space and God’s sensorium by situating those claims within Newton’s philosophical thought. The second is to show how my interpretation rescues Newton from Leibniz’s critiques. I show that Newton had a considered position on the sensorium and the role it played in sensation and volition. The primary evidence for this comes from an experiment Newton performed involving after-images; an experiment he recorded in his student notebook and corresponded with Locke about. I also discuss Newton’s views on mind-body causation, divine extension, and divine analogy. My final position is that we should read Newton as claiming that space in the venue in which God exercises his divine will. I also consider the problem of the missing tanquam pointed out by Koyré and Cohen and propose a solution. (shrink)

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Este texto pretende apresentar, de forma sucinta, um conjunto de estratégias de ?folósofos modernos para a retomada e crítica do ceticismo antigo, procurando destacar algumas semelhanças e diferenças.

Russell's book The Problems of Philosophy was first published a hundred years ago.¹ A remarkable feature of this enduring text is the glint of Platonism it presents on a dark empiricist sea: while our knowledge of physical objects is entirely mediated by direct awareness of sense data, we can also have direct awareness of certain universals, Russell claims.² This is questionable, even if one has no empiricist inclination. Universals are abstract, hence causally inert. How, then, can we have any knowledge (...) of them, direct or indirect? This paper is about Russell's answer to that question. I will argue that given some modification and elaboration of Russell's views, his claim that some universals are knowable by acquaintance is plausible. (shrink)

After a brief outline of the topic of non-language thinking in mathematics the central phenomenological tool in this concern is established, i.e. the eidetic method. The special form of eidetic method in mathematical proving is implicit variation and this procedure entails three rules that are established in a simple geometrical example. Then the difficulties and the merits of analogical thinking in mathematics are discussed in different aspects. On the background of a new phenomenological understanding of the performance of non-language thinking (...) in mathematics the well-known theses of B. L. van der Waerden that mathematical thinking to a great extent proceeds without the use of language is discussed in a new light. (shrink)

If conceptual analysis is possible for finite thinkers, then there must ultimately be a distinction between complex and primitive or irreducible and unanalyzable concepts, by which complex concepts are analyzed as relations among primitive concepts. This investigation considers the advantages of categorizing intentionality as a primitive rather than analyzable concept, in both a historical Brentanian context and in terms of contemporary philosophy of mind. Arguments in support of intentionality as a primitive relation are evaluated relative to objections, especially a recent (...) criticism by Jerry A. Fodor. Against this background, the relation between qualia and intentionality in the understanding of consciousness is explored. (shrink)

This paper offers a critique of a central psychopathological concept, the notion of "poor reality-testing. "Using ideas from the philosopher Ludwig Wittgenstein, I consider the nature of delusions in schizophrenia, largely through examining Daniel Paul Schreber's famous Memoirs of My Nervous Illness. Many schizophrenic individuals do not in fact mistake their fantasies for reality, as is traditionally assumed. Rather, I argue, they engage in a solipsistic mode of experience, a felt subjectivization of the lived world that is associated with a (...) stance of passivity and hyperconsciousness. I discuss the existential conditions and consequences of this stance and show that certain anomalous or paradoxical features of schizophrenic delusion are explicable on this phenomenological account.

Thirty years ago, grounded cognition had roots in philosophy, perception, cognitive linguistics, psycholinguistics, cognitive psychology, and cognitive neuropsychology. During the next 20 years, grounded cognition continued developing in these areas, and it also took new forms in robotics, cognitive ecology, cognitive neuroscience, and developmental psychology. In the past 10 years, research on grounded cognition has grown rapidly, especially in cognitive neuroscience, social neuroscience, cognitive psychology, social psychology, and developmental psychology. Currently, grounded cognition appears to be achieving increased acceptance throughout cognitive (...) science, shifting from relatively minor status to increasing importance. Nevertheless, researchers wonder whether grounded mechanisms lie at the heart of the cognitive system or are peripheral to classic symbolic mechanisms. Although grounded cognition is currently dominated by demonstration experiments in the absence of well-developed theories, the area is likely to become increasingly theory driven over the next 30 years. Another likely development is the increased incorporation of grounding mechanisms into cognitive architectures and into accounts of classic cognitive phenomena. As this incorporation occurs, much functionality of these architectures and phenomena is likely to remain, along with many original mechanisms. Future theories of grounded cognition are likely to be heavily influenced by both cognitive neuroscience and social neuroscience, and also by developmental science and robotics. Aspects from the three major perspectives in cognitive science—classic symbolic architectures, statistical/dynamical systems, and grounded cognition—will probably be integrated increasingly in future theories, each capturing indispensable aspects of intelligence.

For a long time, under the influence of traditional Western philosophy, Orthodox interpreters have distorted Marx’s philosophy as the ontology of matter, thereby concealing the essence of Marx’s philosophy, and eliminating the fundamental difference between Marx’s philosophy and traditional philosophy. This paper proposes that Marx’s philosophy is not the ontology of matter, but on the contrary, by examining the ontology of matter, Marx put forward his own ontological theory, i.e., the ontology of the praxis-relations of social production, by which Marx (...) linked the realms of phenomenon and essence, revealing the content and essence of his philosophy.

At the turn of the twentieth century, a number of philosophers introduced the idea of philosophical research on cognition that could enter into competition with psychology, which was developing into an autonomous discipline at that time. In view of the problems of the traditional but still prevailing associationist theory, Ernst Cassirer demanded a more sophisticated theory that could explain the human ability to concentrate one's thoughts on a topic, such as a problem or a task. He presented a representational theory (...) of mind to explain this ability. This paper explicates the scope of this theory and Cassirer's idea of interdisciplinary cooperation between philosophers and psychologists. (shrink)

Philosophers have long sought to explain perceptual constancy—the fact that objects appear to remain the same color, size and shape despite changes in the illumination condition, perspective and the relative distance—in terms of a mechanism that actively categorizes variable stimuli under the same pre-formed conceptual categories. Contemporary representationalists, on the other hand, explain perceptual constancy in terms of a modular mechanism that automatically discounts variation in the visual field to represent the stable properties of objects. In this paper I argue (...) that while the former view is unmotivated by empirical evidence, the later fails to account for inter- and intra-personal variability, the influence of expectations on constancy, and the systematic and normal failures of color constancy. A Bayesian approach that builds on the representational tradition in psychology solves both problems. (shrink)

Realism concerning a given domain of things is the view that the things in that domain exist, and are as they are, quite independently of anyone.

In one of the closing paragraphs of Treatise Book 1, Hume provocatively concludes: ‘Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous’ . Unlike the first clause, the meaning of the second clause is far from obvious. I claim that errors in philosophy are ‘only ridiculous’ for Hume in the sense that – unlike errors in religion – they fail to disturb us psychologically or in practical life. The interesting question, however, is why they fail to (...) disturb us. I suggest that it is their critical role in resolving the psychological instability brought on by philosophical reflection that makes errors in philosophy quite helpful to us and necessary for re-stabilising ourselves. In recognising a positive role for philosophical errors, my account challenges the standard interpretation of Hume's claim according to which ‘ridiculous’ philosophical errors play the merely negative role of being innocuous or safely dismissed.

I defend (metaphysical) ground against recent, unanswered objections aiming to dismiss it from serious philosophical inquiry. Interest in ground stems from its role in the venerable metaphysical project of identifying which facts hold in virtue of others. Recent work on ground focuses on regimenting it. But many reject ground itself, seeing regimentation as yet another misguided attempt to regiment a bad idea (like phlogiston or astrology). I defend ground directly against objections that it is confused, incoherent, or fruitless. This vindicates (...) the very attempt to regiment ground. It also refocuses our attention on the genuine open questions about ground and away from the distracting, unpersuasive reasons for dismissing them. (shrink)

To have the burden of proof is to be rationally required to argue for or provide evidence for your position. To have a heavier burden than an opponent is to be rationally required to provide better evidence or better arguments than they are required to provide. Many commentators suggest that differential or uneven distribution of the burden of proof is ubiquitous. In reasoned discourse, the idea goes, it is almost always the case that one party must prove the claim at (...) issue to prevent the opposing view winning by default. The following passage is typical of the sort of thing one finds in critical thinking textbooks. (shrink)

This paper discusses some key connections between Berkeley's reflections on language in the introduction to his Treatise on the Principles of Human Knowledge and the doctrines espoused in the body of that work, in particular his views on vulgar causal discourse and his response to the objection that his metaphysics imputes massive error to ordinary thought. I argue also that there is some mileage in the view that Berkeley's thought might be an early form of non-cognitivism.

In this paper I shall attempt to argue for the simple view of personal identity. I shall first argue that we often do have warrant for our beliefs that we exist as continuing subjects of experience, and that these beliefs are justified independently of any reductionist analysis of what it means to be a person. This has two important implications that are relevant to the ongoing debate concerning the number of persons that are in existence throughout any duration in time: (...) (1) the lack of logically or metaphysically necessary and sufficient conditions for distinguishing one person from another should imply neither that there is only one person nor that personhood is not individuative; and (2) the lack of such universally applicable identity criteria should not imply that the term ‘person’ is a folk term with no real application. In other words, lack of reductionist analysis does not entail lack of existence. (shrink)

Theories concerning the structure, or format, of mental representation should (1) be formulated in mechanistic, rather than metaphorical terms; (2) do justice to several philosophical intuitions about mental representation; and (3) explain the human capacity to predict the consequences of worldly alterations (i.e., to think before we act). The hypothesis that thinking involves the application of syntax-sensitive inference rules to syntactically structured mental representations has been said to satisfy all three conditions. An alternative hypothesis is that thinking requires the construction (...) and manipulation of the cognitive equivalent of scale models. A reading of this hypothesis is provided that satisfies condition (1) and which, even though it may not fully satisfy condition (2), turns out (in light of the frame problem) to be the only known way to satisfy condition (3).

Philosophers often aim to demonstrate that the things we ordinarily think and say can be reconciled with our considered beliefs about the world. To this end, many philosophers try to paraphrase ordinary language claims by finding equivalent sentences that are less misleading. For instance, though we know that there is no British family that is the average one, we want to say that the average British family has 1.8 children, and we might do that by paraphrasing this claim as: there (...) are nearly twice as many British children as British families. This article aims to introduce and distinguish different paraphrase strategies, sketch their role in metaphysical debates and highlight some crucial questions that proponents of such strategies face.

How does the modern scientific conception of time constrain the project of assigning the mind its proper place in nature? On the scientific conception, it makes no sense to speak of the duration of a pain, or the simultaneity of sensations occurring in different parts of the brain. Such considerations led Henri Poincaré, one of the founders of the modern conception, to conclude that consciousness does not exist in spacetime, but serves as the basic material out of which we must (...) create the physical world. The central claim of Sensorama is that Poincaré was substantially correct. The best way to reconcile the scientific conception of time with the evidence of introspection is through a phenomenalist metaphysic according to which consciousness exists in neither time nor space, but serves as a basis for the logical construction of spacetime and its contents.

In order to make reliable predictions in any region of human activity, it is necessary to distinguish clearly what is based on experience and what is a construction of intellect. The theory of knowledge developed in the present paper is an attempt to devise a set of axioms that demarcate experience, as the only source of our knowledge of the external world, from the ideas, scientific models, and theories by means of which the scientific predictions are made. After a discussion (...) of the causality in relation to the laws of nature, the axioms of the expounded theory are formulated in the formalism of set theory. The theory is then applied to some problems in physics to demonstrate its usefulness. (shrink)
