Locke: Representation

Much recent philosophy of perception is preoccupied with finding a place for phenomenal character in a physical world. By contrast, Locke’s philosophy of sensory perception is an episode in his ‘Historical, plain method’ and seeks to map out the processes by which we experience ordinary objects. On Locke’s account, our ideas of primary and secondary qualities enter the mind ‘simple and unmixed’; having an idea of a colour, for example, is not necessary for the visual experience of a shape. An (...) analysis of the Molyneux problem reveals that, for Locke, judgment corrects the initial two-dimensional idea vision presents us with. Nevertheless, Locke’s position is problematic: he has no account of how we pair ideas of primary and secondary qualities, nor of how we could experience a colourless visual idea of shape. (shrink)

How much is given in perceptual experience, and how much must be constructed? John Locke's answer to this question contains two prima facie incompatible strands. On the one hand, he claims that ideas of primary qualities come to us passively, through multiple senses: the idea of a sphere can be received either by sight or touch. On the other hand, Locke seemingly thinks that a faculty he calls “judgment” is needed to create visual ideas of three‐dimensional shapes. How can these (...) accounts be made consistent? The problem comes to a head in the discussion of Molyneux's problem: can a person born blind and then made to see identify a sphere and a cube, when he had only touched them in the past? Locke's answer is no, but, as George Berkeley points out, it is hard to see why: if the ideas of shapes come to us through sight as well as touch, nothing should stop Molyneux man from instantly recognizing sphere and cube. Pace much of the existing literature, I argue that although Locke does think we receive visual ideas of primary qualities, the faculty of judgment is required to “inflate” those ideas into three dimensions and to correct for other perspectival distortions. I then show how this answer is consistent with the rest of his theory of perception. (shrink)

En su Tratado sobre los principios del conocimiento humano, George Berkeley ofrece una serie de argumentos cuyo objetivo es criticar la tesis materialista. Mi propósito en este artículo es reconstruir y analizar en detalle estos argumentos. Dado que la crítica de Berkeley al materialismo es, fundamentalmente, una crítica al materialismo representacionalista de John Locke, empezaré este artículo explicando cuáles son las ideas básicas de la propuesta de Locke.

Michael Jacovides provides an engaging account of how the scientific revolution influenced one of the foremost figures of early modern philosophy, John Locke. By placing Locke's thought in its scientific, religious, and anti-scholastic contexts, Jacovides explains not only what Locke believes but also why he believes it.

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. (shrink)

This paper examines the pressures leading two very different Early Modern philosophers, Descartes and Locke, to invoke two ways in which thought is directed at objects. According to both philosophers, I argue, the same idea can simultaneously count as “of” two different objects—in two different senses of the phrase ‘idea of’. One kind of intentional directedness is invoked in answering the question What is it to think that thus-and-so? The other kind is invoked in answering the question What accounts for (...) the success of our proper methods of inquiry? For Descartes as well as Locke, the two kinds of “ofness” come apart as a result of strong rationalist commitments. However, I will suggest that even if we reject such commitments, we go wrong if we assume that a single kind of intentional directedness suffices to address both questions. (shrink)

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.

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. (shrink)

Locke’s argument for the primary-secondary quality distinction is compared with Descartes’s argument (in the Principles of Philosophy) for the distinction between mechanical modifications and sensible qualities. I argue that following Descartes, Locke’s argument for the primary-secondary quality distinction is an essentially a priori argument, based on our conception of substance, and the constraints on intelligible bodily interaction that this conception of substance sets.

The paper argues for the view advocated by Yolton that Locke's ideas are best viewed as intentional contents. Drawing on Smith and McIntyre's distincition between object- and content-theories of intentionality I seek it show that it belongs to the second category. The argument relies mainly on the analysis of Locke's discussion of meaning, the reality and adequacy of ideas and real essence.

This paper argues that Locke has a representative theory of sensitive knowledge. Perceivers are immediately aware of nothing but sensory ideas in the mind; yet perceivers think of real external substances that correspond to and cause those ideas, and they are warranted in believing that those substances exist (at that time). The theory poses two questions: what warrants the truth of such beliefs? What is it in virtue of which sensory ideas represent external objects and how do they make perceivers (...) think of those objects? Both the epistemic and semantic issues need to be addressed. This paper urges that Locke's basic account of warrant is roughly reliabilist. The causal origin of sensory ideas assures that, in general, sense based beliefs are true. Locke defines the limit of this warrant by the theoretical point that we cannot discuss skeptical doubt without assuming the truthfulness of our perceptual faculty. Turning to the semantic question, the paper argues that ideas are mental modifications or entities. They are not intrinsically representative (satisfiable), but rather represent only by virtue of their causal origin. They merely “track” the presence of substances and their qualities. Ideas nevertheless prompt perceivers to think of their causes. This is roughly because sensory ideas have a specific mental role, namely, to serve as marks for distinguishing substances and their respective qualities for purposes of action. The paper suggests that, for Locke, the challenge posed by the semantic veil of ideas is to explain this externally directed marking function within bounds of his anti‐innatism. But it concludes that his answers to the twin questions fit together reasonably well. (shrink)

El hecho de que este año 2004 se cumpla el tercer centenario de la muerte de J. Locke ya de por sí es una ocasión para repasar su pensamiento como uno de los más influyentes en la tradición filosófica, especialmente en la anglosajona. Más oportuno aún es repensarlo a la luz de las consecuencias de sus planteamientos no sustancialistas. En el terreno gnoseo lógico, si de la sustancia no tenemos una idea clara y distinta entonces se alza con toda crudeza (...) el problema del correlato de nuestras ideas: su significado y su referencia. De la consideración de las ideas como signos surge una visión de las posiciones de Locke, inicialmente catalogadas de representacionistas, que las sitúa en el ámbito de la expresión. (shrink)

The topic of this dissertation is a discussion of the seventeenth century debate between Descartes and Locke over innate ideas. I propose a novel approach to the study of this debate. I argue that their disagreement over innate ideas is directly related to their differing views of how the content of ideas is determined and of what counts as having an idea in the mind. Approaching the controversy between Descartes and Locke from this perspective has allowed me to conclude that (...) Descartes' nativist argument prevail over Locke's arguments to the contrary. ;I begin the discussion, in Chapter One, by examining the anti-nativist arguments offered by Locke in Book I of his Essay concerning Human Understanding and by clarifying the nature of Descartes' dispositional nativism. I conclude that since Locke's arguments rely on a principle whose denial is implied by Descartes' Dispositional Nativism, his arguments at best beg the question against Descartes. I suggest then that discussion of the controversy between Descartes and Locke should shift to the arguments they provide, respectively, for and against the awareness principle. ;In Chapter Two, I argue that Locke's argument for the awareness principle is to be found in the empiricism of Book II of his Essay and, hence, that the anti-nativist arguments of Book I are question-begging since they presuppose the very empiricism they aim to prove. ;In Chapters Three and Four, I argue that Descartes' argument for the denial of the awareness principle is to be found in his rationalist theory of idea-individuation according to which the content of ideas is determined by an intellectual and implicitly known presentation of the object. ;In the final chapter, I argue that Descartes' arguments for nativism are a version of what is known in the literature as "Poverty-of-the-Stimulus Arguments" and conclude that, interpreted this way, they have an edge over Locke's anti-nativist arguments. I contend that whereas Locke's argument for the awareness principle depend on an empiricist theory of idea individuation that assumes that principle, Descartes' argument for the denial of the awareness principle depends on a rationalist theory of idea individuation that argues for the denial of that principle.

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

Our reading is a passage from John Locke, An Essay Concerning Human Understanding, Book III, Chapter II, § 2.When a man speaks to another, it is that he may be understood; and the end of speech is that those sounds, as marks, may make known his ideas to the hearer. … Words being voluntary signs, they cannot be voluntary signs imposed by him on things he knows not. That would be to make them signs of nothing, sounds without signification.

Locke asserts that “the Ideas of primary Qualities of Bodies, are Resemblances of them, and their Patterns do really exist in the Bodies themselves; But the Ideas, produced in us by these Secondary Qualities, have no resemblance of them at all.”1 On an unsophisticated way of taking his words, he means that ideas of primary qualities are like the qualities they represent and ideas of secondary qualities are unlike the qualities they represent.2 I will show that if we take his (...) assertions in this unsophisticated way, our reward will be a straightforward and satisfying interpretation of the central arguments of his chapter on primary and secondary qualities. With these arguments, Locke attempts to justify his assertions about resemblance. Some may be skeptical, thinking that the assertions, interpreted literally, are either too absurd or too obvious to have reasons supporting them. I take this skepticism to rest on deep foundations of charity, so half of the paper will be devoted to undermining these foundations by giving a sympathetic and historical exposition of Locke’s positive thesis that primary qualities resemble the ideas that represent them. I criticize rival interpretations of Lockean resemblance, say what it means to believe that ideas resemble qualities, explain the plausibility of the belief in Locke’s environment, and examine his descriptions of how ideas resemble particular primary qualities. Once I establish that we should take Locke’s resemblance theses literally, I can describe their place in his theory of representation. After that, I can describe his reasons for believing the resemblance theses. I will conclude by showing how Locke’s belief that ideas of secondary qualities do not resemble anything in bodies leads him to conclude that secondary qualities are merely powers to produce ideas. Let me begin near the end, however. Before defending a literal interpretation of the resemblance theses, I want to criticize three rival interpretations.. (shrink)

Tandis que l'histoire de la philosophie est traversée par la dichotomie entre le réalisme des universaux et le nominalisme, on tend à négliger la position intermédiaire — le conceptualisme — dont on a fait de Locke le plus illustre représentant, mais qu'on a tenu pour disqualifié par les célèbres critiques de Berkeley ou Leibniz. On peut cependant montrer que le conceptualisme est doublé d'une ontologie sous-jacente qui pourrait fournir aux philosophes contemporains une alternative originale à la philosophie des universaux. Whereas (...) the dichotomy between realism and nominalism, makes the problem of Universais a paradigm case of a philosophical problem, the mediate view put forward by conceptualism is generally neglected as being an erroneous view on language. Nevertheless, conceptualism is the counterpart of an original ontology — the philosophy of Resemblances — which might be regarded an alternative to the philosophy of Universals. (shrink)

Locke's Essay concerning Human Understanding has generally been read as primarily concerned with epistemology. In particular, it has been claimed that the Essay attempts to defeat epistemological skepticism, but fails in this enterprise because of the veiling character of Locke's ideas. By way of reexamination of the texts in question I show that epistemological skepticism is not the topic of the Essay, and that there is not sufficient reason to claim that Locke's account of knowledge leads to epistemological skepticism. I (...) argue, moreover, that the motivating topic of the Essay is moral skepticism, and I explain the central role of ch. 8, book 2 in Locke's argumentation for the claim that we may achieve a science of morality. I conclude with an account of some of practical consequences of a science of morality, as conceived by Locke. (shrink)

This paper is a defense of the “representative theory of perception” in general, and Locke's views about perception in particular. It is intended only as a limited defense, but one against those objections which recently have been taken thoroughly to discredit both the general theory and Locke's particular position. The chief of these objections is that the representative theory leads inevitably to skepticism about the existence of objective material things. George Pitcher finds this objection to the representative theory completely persuasive (...) and so well established that it scarcely requires discussion:It is just here [in the area of justifying perceptual knowledge of the world] that the most serious and notorious deficiencies of sense-datum theories are encountered. If the sense-datum theorist maintains the existence of physical objects, … as ordinarily conceived, then his claim that sense-data are metaphysically distinct from anything in the physical world commits him to a version of representative realism. The enormous epistemological difficulties [due to their skeptical consequences] faced by theories of this kind are well known, and I shall not say anything about them, except that I regard them as insuperable ….
