LOCKE ON IDEAS OF SUBSTANCE AND THE VEIL OF PERCEPTION

Abstract: John Yolton has argued that Locke held a direct realist position according to which sensory ideas are not perceived intermediaries, as on the representational realist position, but acts that take material substances as objects. This paper argues that were Locke to accept the position Yolton attributes to him he could not at once account for appearance‐reality discrepancies and maintain one of his most important anti‐nativist arguments. The paper goes on to offer an interpretation of Locke's distinction between ideas of substances and modes, a distinction that helps Locke to explain appearance‐reality discrepancies, although not in a large enough range of cases to strengthen Yolton's interpretation.     

Boyle's corpuscular hypothesis and Locke's primary-secondary quality distinction

Locke denied that ideas of secondary qualities resemble their causes. It has been suggested that Locke denied this because he accepted a mechanical corpuscular hypothesis about the constitution of objects. This paper shows that this and other usual explanations of Locke's denial are mistaken. Further, it suggests an alternative relationship between the scientific account and Locke's philosophical views, and finally it provides Locke's real justification for his claim that ideas of secondary qualities do not resemble their causes.This paper was prepared with the assistance of a SUNY UAC/JAC Faculty Research Fellowship.     

Hume’s naturalistic theory of representation

Hume is a naturalist in many different respects and about many different topics; this paper argues that he is also a naturalist about intentionality and representation. It does so in the course of answering four questions about his theory of mental representation: (1) Which perceptions represent? (2) What can perceptions represent? (3) Why do perceptions represent at all? (4) Howdo perceptions represent what they do? It appears that, for Hume, all perceptions except passions can represent; and they can represent bodies, minds, and persons, with their various qualities. In addition, ideas can represent impressions and other ideas. However, he explicitly rejects the view that ideas are inherently representational, and he implicitly adopts a view according to which things (whether mental or non-mental) represent in virtue of playing, through the production of mental effects and dispositions, a significant part of the causal and/or functional role of what they represent. It is in virtue of their particular functional roles that qualitatively identical ideas are capable of representing particulars or general kinds; substances or modes; relations; past, present, or future; and individuals or compounds.     

Lockean Empathy

This paper offers an epistemic defense of empathy, drawing on John Locke's theory of ideas. Locke held that ideas of shape, unlike ideas of color, had a distinctive value: resembling qualities in their objects. I argue that the same is true of empathy, as when someone is pained by someone's pain. This means that empathy has the same epistemic value or objectivity that Locke and other early modern philosophers assigned to veridical perceptions of shape. For this to hold, pain and pleasure must be a primary quality of the mind, just as shape is a primary quality of bodies. Though Locke did not make that claim, I argue that pain and pleasure satisfy his criteria for primary qualities. I consider several objections to the analogy between empathy and shape‐perception and show how Locke's theory has resources for answering them. In addition, the claim that empathetic ideas are object‐matching sidesteps Berkeley's influential objection to Locke's theory of resemblance. I conclude by briefly considering the prospects for a similar defense of empathy in contemporary terms.     

Consciousness as sensory quality and as implicit self-awareness

When a mental state is conscious – in the sense that there is something it is like for the subject to have it – it instantiates a certain property F in virtue of which it is a conscious state. It is customary to suppose that F is the property of having sensory quality. The paper argues that this supposition is false. The first part of the paper discusses reasons for thinking that unconscious mental states can have a sensory quality, for example in cases of absent-minded perception. If unconscious mental states can have a sensory quality, then sensory quality is an insufficient condition for consciousness. The second part of the paper argues that there are even better reasons to think that sensory quality is an unnecessary condition for consciousness. The idea is that mental states can be conscious even when they lack sensory quality, for example, in the case of certain conscious propositional attitudes. In the third part of the paper, an alternative to the rejected supposition, drawn from the phenomenological tradition, is offered: that consciousness is a matter of implicit self-awareness, rather than of sensory quality. According to this alternative, a mental state is conscious when, and only when, it involves implicit self-awareness.     

Attributions of intergroup bias and outgroup homogeneity to ingroup and outgroup others

The research in this article explores the structure and content of attributed intergroup beliefs: to what extent do perceivers think others of their ingroup and their outgroup display intergroup evaluative bias and outgroup homogeneity? We report studies that address this question in ethnicity, gender, and nationality intergroup contexts. In all of these, we show that perceivers attribute to others more biased intergroup beliefs than they themselves espouse. Even when perceivers themselves do not show intergroup bias or outgroup homogeneity, they attribute such biases to others, both others from their ingroup and others from their outgroup. We argue that such attributed intergroup beliefs are fundamentally important to expectations concerning intergroup interaction. Copyright © 2005 John Wiley & Sons, Ltd.     

LOCKE AND THE OBJECTS OF PERCEPTION

Abstract: It is common to assume that if Locke is to be regarded as a consistant epistemologist he must be read as holding that either ideas are the objects of perception or that [physical] objects are. He must either be a direct realist or a representationalist. But perhaps, paradoxical as it at first sounds, there is no reason to suppose that he could not hold both to be true. We see physical objects and when we do so we have ideas. We see or hear birds and bells but we also have visual and auditory ideas of birds and bells. This suggestion is explored through examination of what Locke says about perception in his Elements of Natural Philosophy and the accounts offered both by Locke in the Essay Concerning Human Understanding and by some of Locke's successors.     

Sensations as Representations in Kant

This paper defends an interpretation of the representational function of sensation in Kant's theory of empirical cognition. Against those who argue that sensations are ‘subjective representations’ and hence can only represent the sensory state of the subject, I argue that Kant appeals to different notions of subjectivity, and that the subjectivity of sensations is consistent with sensations representing external, spatial objects. Against those who claim that sensations cannot be representational at all, because sensations are not cognitively sophisticated enough to possess intentionality, I argue that Kant does not use the term ‘Vorstellung’ to refer to intentional mental states exclusively. Sensations do not possess their own intentionality, but they nevertheless perform a representational function in virtue of their role as the matter of empirical intuition. In empirical intuition, the sensory qualities given in sensation are combined with the representation of space to constitute the intuited appearance. The representational function of sensation consists in sensation being the medium out of which intuited appearances are constituted: the qualities of sensations stand in for what the understanding will judge (conceptualize) as material substance.     

Locke on Knowing Our Own Ideas (and Ourselves)

Locke defines knowledge as the perception of the agreement or disagreement of ideas. Nevertheless, he claims that we know particular things: the identity of our ideas, our own existence, and the existence of external objects. Although much has been done to reconcile the definition of knowledge with our knowledge of external objects, there is virtually nothing in the scholarship when it comes to knowing ideas or our own existence. I fill in this gap by arguing that perceptions of ideas are complex mental states that convey propositional knowledge due to agreeing elements therein.     

The ontology of character traits in Hume

This paper argues that Hume can account for character traits as lasting mental qualities without violating his reductionist account of the mind as a changing bundle of ideas and impressions. It argues that a trait is a disposition to act according to certain passions or motivations, explained entirely with reference to the ideas and impressions constituting one's current self. This account is consistent with Hume's view of the mind, and relies solely on his accounts of the association of impressions and ideas, and of the relationship between belief and passion, to establish relations that can properly be called lasting mental qualities.     

INTRODUCTION: VIRTUE AND VICE

Abstract: This introduction to the collection Virtue and Vice, Moral and Epistemic addresses three main questions: (1) What is a virtue theory in ethics or epistemology? (2) What is a virtue? and (3) What is a vice? (1) It suggests that a virtue theory takes the virtues and vices of agents to be more fundamental than evaluations of acts or beliefs, and defines right acts or justified beliefs in terms of the virtues. (2) It argues that there are two important but different concepts of virtue: virtues are qualities that attain good ends, and virtues are qualities that involve good motives. (3) Accordingly, vices are qualities that either fail to attain good ends or involve bad motives. Finally, the introduction summarizes the eleven essays in the collection, which are divided into four sections: the Structure of Virtue Ethics and Virtue Epistemology; Virtue and Context; Virtue and Emotion; and Virtues and Vices.     

Recent Scholarship on Hume's Theory of Mental Representation

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

Cognitive Architecture, Concepts, and Introspection: An Information‐Theoretic Solution to the Problem of Phenomenal Consciousness

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information‐theoretic framework of Dretske (1981) , we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so‐called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so‐called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.     

Locke on Individuation and the Corpuscular Basis of Kinds1

In this paper, I examine the crucial relationship between Locke’s theory of individuation and his theory of kinds. Locke holds that two material objects—e.g., a mass of matter and an oak tree—can be in the same place at the same time, provided that they are ‘of different kinds’. According to Locke, kinds are nominal essences, that is, general abstract ideas based on objective similarities between particular individuals. I argue that Locke’s view on coinciding material objects is incompatible with his view on kinds. In order for two material objects to be in the same place at the same time, they must differ with respect to at least one nominal essence. However, Locke thinks that it is impossible that x and y have the same real essence but differ with respect to any nominal essence; and coinciding material objects have the same real essence. Therefore, Locke cannot hold what he in fact holds, namely that distinct material objects can be in the same place at the same time.     

TWO KINDS OF INTENTIONALITY IN LOCKE

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities.     

A Theory of Secondary Qualities

The secondary qualities are those qualities of objects that bear a certain relation to our sensory powers: roughly, they are those qualities that we can readily detect only through a certain distinctive phenomenal experience. Contrary to what is sometimes supposed, there is nothing about the world itself (independent of our minds) that determines the distinction between primary and secondary qualities. Instead, a theory of the secondary qualities must be grounded in facts about how we conceive of these qualities, and ultimately in facts about human perception.     

SYMPOSIUM: LOCKE AND THE VEIL OF PERCEPTION Preface

Abstract: This Symposium comprises five papers on Locke's theory of sense perception. The authors are John Rogers, Gideon Yaffe, Lex Newman, Tom Lennon, and Martha Bolton. There are also comments on the papers, both individually and as a group, by Vere Chappell. In addition to Locke's view of perception, the papers deal with the nature of Lockean ideas and with the question whether Locke is committed to skepticism regarding the external world. The authors (and the commentator) disagree in their readings of Locke on these issues, but most maintain – and some argue – that he holds a representative theory of perception, and that he is not an external‐world skeptic.     

Defeat and proficiencies

Virtue epistemology is the view that beliefs are attempts at truth (or perhaps knowledge) and, as a result, can be assessed as successful, competent, and apt. Moreover, virtue epistemology identifies central epistemic properties with normative properties of beliefs as attempts. In particular, knowledge is apt belief and justified belief is competent belief. This paper develops a systematic virtue epistemological account of defeat (of justification/competence). I provide reason to think that defeat occurs not only for beliefs but for attempts more general. The key constructive idea is that defeaters are evidence that attempting (in a certain way) isn't successful and that defeaters defeat the competence of an attempt when one stands in a certain normative relation to the defeater. I argue that while this account handles paradigm cases of defeat both within epistemology and beyond nicely, cases of external (sometimes also ‘normative’ or ‘propositional’) defeat continue to cause trouble. To handle these cases, I develop a distinctively functionalist version of virtue epistemology. This functionalist version of virtue epistemology allows me to countenance proficiencies, that is, roughly, abilities that have the function to produce successes under certain conditions. It is the normative import of proficiencies that delivers the normative relation that serves to explain defeat in cases of external defeat. In this way, the functionalist version of virtue epistemology ushers the way towards a satisfactory account even of external defeat.     

Qualitative character and sensory representation

Perceptual experience seems to involve distinct intentional and qualitative features. Inasmuch as one can visually perceive that there is a Coke can in front of one, perceptual experience must be intentional. But such experiences seem to differ from paradigmatic intentional states in having introspectible qualitative character. argues that a perceptual experience's qualitative character is determined by intrinsic, nonrepresentational properties. But also argues that perceptual experiences have nonconceptual representational content in addition to conceptual content and nonrepresentational sensational properties. He thus distinguishes between conceptual, nonrepresentational, and nonconceptual but representational aspects of perceptual experience. I will argue that Peacocke posits too much. Contrary to his (1983) arguments, the sensational properties Peacocke claims are nonrepresentational are best construed as representational; they are best explained in terms of their relation to the perceptible properties they enable us to perceive. Since sensational properties are arguably nonconceptual, they are best construed as nonconceptual representational properties. I offer the Homomorphism View of sensory qualities, pioneered by, as a unified account of qualitative character and nonconceptual sensory representation. According to this view, a sensory quality represents a perceptible stimulus property in virtue of resembling and differing from other sensory qualities in ways parallel to the ways the stimulus property resembles and differs from other perceptible properties.     

What is Locke's Theory of Representation?

On a currently popular reading of Locke, an idea represents its cause, or what God intended to be its cause. Against Martha Bolton and my former self (among others), I argue that Locke cannot hold such a view, since it sins against his epistemology and theory of abstraction. I argue that Locke is committed to a resemblance theory of representation, with the result that ideas of secondary qualities are not representations.
