In the Introduction to the Treatise concerning the Principles of Human Knowledge, Berkeley attacks the “received opinion that language has no other end but the communicating our ideas, and that every significant name stands for an idea” (PHK, Intro §19). How far does Berkeley go in rejecting this ‘received opinion’? Does he offer a general theory of language to replace it? If so, what is the nature of this theory? In this chapter, I consider three main interpretations of Berkeley's view: (...) the modified ideational theory, the speaker intentions theory, and the use theory. I argue that the use theory does, and its competitors do not, make sense of Berkeley's remarks on language in both the earlier and later works. (shrink)

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

During the past few decades, a radical shift has occurred in how philosophers conceive of the relation between science and philosophy. A great number of analytic philosophers have adopted what is commonly called a ‘naturalistic’ approach, arguing that their inquiries ought to be in some sense continuous with science. Where early analytic philosophers often relied on a sharp distinction between science and philosophy—the former an empirical discipline concerned with fact, the latter an a priori discipline concerned with meaning—philosophers today largely (...) follow Willard Van Orman Quine (1908-2000) in his seminal rejection of this distinction. -/- This book offers a comprehensive study of Quine’s naturalism. Building on Quine’s published corpus as well as thousands of unpublished letters, notes, lectures, papers, proposals, and annotations from the Quine archives, this book aims to reconstruct both the nature (chapters 2-4) and the development (chapter 5-7) of his naturalism. As such, this book aims to contribute to the rapidly developing historiography of analytic philosophy, and to provide a better, historically informed, understanding of what is philosophically at stake in the contemporary naturalistic turn.

John Locke’s claims about relations (such as cause and effect) and mixed modes (such as beauty and murder) have been controversial since the publication of the Essay. His earliest critics read him as a thoroughgoing anti-realist who denies that such things exist. More charitable readers have sought to read Locke’s claims away. Against both, I argue that Locke is making ontological claims, but that his views do not have the absurd consequences his defenders fear. By examining Locke’s texts, as well (...) as the intellectual context in which they were written, I show that Locke’s position is at once radical and thoroughly traditional. (shrink)

En este ensayo analizaremos el argumento que usa Berkeley para probar la existencia de Dios en el Tratado sobre los principios del conocimiento humano I, §29. Veremos cuál es la estructura del argumento, la justificación que ofrece Berkeley de sus premisas y expondremos los que creemos son los principales problemas del argumento. A partir de nuestro análisis, llegaremos a la conclusión de que el argumento es dialécticamente inútil, en tanto que sus premisas no están justificadas.

Discussions of John Locke’s theory of causation tend, understandably, to focus on the related notion of power and in particular the dialectic with David Hume. But Locke faces a very different threat, one that is internal to his view. For he argues both that causation is a relation and that relations are not real. The obvious conclusion is intolerable. And yet the premises, I argue, are unassailable. Building on an interpretation of Locke’s treatment of relations I have developed elsewhere, I (...) show how Locke can at once speak meaningfully of causation and deny its mind-independent existence. (shrink)

A standard interpretation of Hume’s naturalism is that it paved the way for a scientistic and ‘disenchanted’ conception of the world. My aim in this paper is to show that this is a restrictive reading of Hume, and it obscures a different and profitable interpretation of what Humean naturalism amounts to. The standard interpretation implies that Hume’s ‘science of human nature’ was a reductive investigation into our psychology. But, as Hume explains, the subject matter of this science is not restricted (...) to introspectively accessible mental content and incorporates our social nature and interpersonal experience. Illuminating the science of human nature has implications for how we understand what Hume means by ‘experience’ and thus how we understand the context of his epistemological investigations. I examine these in turn and argue overall that Hume’s naturalism and his science of man do not simply anticipate a disenchanted conception of the world. (shrink)

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)

Exposing the chimpanzee to language training appears to enhance the animal's ability to perform some kinds of tasks but not others. The abilities that are enhanced involve abstract judgment, as in analogical reasoning, matching proportions of physically unlike exemplars, and completing incomplete representations of action. The abilities that do not improve concern the location of items in space and the inferences one might make in attempting to obtain them. Representing items in space and making inferences about them could be done (...) with an imaginal code, but representing relations and judging the relations between them, as in analogies, requires a more abstract code. Language training cannot instill such an abstract code, but for species that have the code to start with, it may enhance the animal's ability to use it. (shrink)

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. (shrink)

The first half of this review article on Locke on primary and secondary qualities leads up to a fairly straightforward reading of what Locke says about the distinction in Essay II.viii, one that, in its general outlines, represents a sympathetic understanding of Locke’s discussion. The second half of the paper turns to consider a few of the ways in which interpreting Locke on primary and secondary qualities has proven more complicated. Here we take up what is sometimes called the Berkeleyan (...) interpretation of Locke, the understanding of Locke’s resemblance thesis, and Locke’s views of qualities and their relationship to powers.

In this paper I propose we read David Hume's view of meaningful discourse, or his theory of meaning, as an aspect of his theory of politics. I will argue that readings which ignore the political dimension are incomplete and distort Hume's position. When I use the word ‘political’ in the Humean context, however, it means something similar to what we mean by the term ‘social’; in the Humean context ‘politics’ is inclusive of the narrow sense taken by political science in (...) its study of regular partisan politics and governance structures. My proposal is similar to the social-context or social-constructivist interpretations of commentators such as Pall Ardal, Donald Livingston, and Nicholas Capaldi. A political reading also stresses the importance of social context in our understanding of Hume, and agrees with the social-context argument that there is a social or political dimension to intellectual life which Hume hints at but does not address directly in Book 1 of theTreatise.

It is commonly thought that Hume endorses the claim that causal cognition can be fully explained in terms of nothing but custom and habit. Associative learning does, of course, play a major role in the cognitive psychology of the Treatise. But Hume recognizes that associations cannot provide a complete account of causal thought. If human beings lacked the capacity to reflect on rules for judging causes and effects, then we could not (as we do) distinguish between accidental and genuine regularities, (...) and Hume could not (as he does) carry out his science of human nature. One might reply that what appears to be rule-governed behavior might emerge from associative systems that do not literally employ rules. But this response fails: there is a growing consensus in cognitive science that any adequate account of causal learning must invoke active, controlled cognitive processes. (shrink)

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.

What sort of property did Locke take colors to be? He is sometimes portrayed as holding that colors are wholly subjective. More often he is thought to identify colors with dispositions—powers that bodies have to produce certain ideas in us. Many interpreters find two or more incompatible strands in his account of color, and so are led to distinguish an “official,” prevailing view from the conflicting remarks into which he occasionally lapses. Many who see him as officially holding that colors (...) are dispositions concede that some of his remarks imply that colors are in us rather than in objects. After raising some difficulties for these readings, I offer an alternative. I will argue that Locke takes colors to be relational, but not dispositional, properties of the objects around us. On his view, an object is red if and only if it is actually causing a certain sensation in some observer. (shrink)

An important part of Hume's philosophy is grounded in a fundamental distinction between two kinds of perceptions: impressions and ideas. Existing views of the distinction are that the former are livelier than the latter, that the former are causally prior to the latter, that the latter are copies of the former, that the former but not the latter are perceptions of an objective realm, and that the former are feelings whereas the latter are thoughts. I argue that all of these (...) views of the distinction are problematic and should be replaced by the Reflection view, according to which (simple) ideas are, while impressions are not, the direct products of reflection on other perceptions.

On the assumption that we may learn from our elders and betters, this paper approaches some fundamental questions in perceptual epistemology through a dispute between McDowell and Wright about external world scepticism.

Abductivists claim that explanatory considerations (e.g., simplicity, parsimony, explanatory breadth, etc.) favor belief in the external world over skeptical hypotheses involving evil demons and brains in vats. After showing how most versions of abductivism succumb fairly easily to obvious and fatal objections, I explain how rationalist versions of abductivism can avoid these difficulties. I then discuss the most pressing challenges facing abductivist appeals to the a priori and offer suggestions on how to overcome them.

in The Cambridge Companion to Locke’s Essay, edited by Lex Newman. Cambridge: Cambridge University Press, 2007.

The abductivist reply to skepticism is the view that commonsense explanations of the patterns and regularities that appear in our sensory experiences should be rationally preferred to skeptical explanations of those same patterns and regularities on the basis of explanatory considerations. In this article I critically examine Laurence BonJour’s rationalist version of the abductivist position. After explaining why BonJour’s account is more defensible than other versions of the view, I argue that the notion of probability he relies upon is deeply (...) problematic, that he incorporates an implausible double-standard concerning a priori and a posteriori justification, and that his view is vulnerable to skepticism about the a priori. I suggest that some of these problems are due to idiosyncratic commitments BonJour makes and that abductivists would be better off without them. I conclude with some suggestions about how to improve BonJour’s abductivist response to skepticism. (shrink)

In The Quest for Reality: Subjectivism and the Metaphysics of Colour [Stroud, 2000], Barry Stroud carries out an ambitious attack on various forms of irrealism and subjectivism about color. The views he targets - those that would deny a place in objective reality to the colors - have a venerable history in philosophy. Versions of them have been defended by Galileo, Descartes, Boyle, Locke, and Hume; more recently, forms of these positions have been articulated by Williams, Smart, Mackie, Ryle, and (...) Hardin, among others. Stroud's aim is to argue not only that these writers fail to make their cases, but that no conceivable argument could ever convince us that colors are not a part of objective reality. (shrink)

To the great puzzlement of his readers, Berkeley begins by arguing that nothing exists other than minds and ideas, but concludes by claiming to have defended the existence of bodies. How can Berkeley's idealism amount to such a defense? I introduce resources from Berkeley's philosophy of language, and especially his analysis of the discourse of physics, to defend a novel answer to this question. According to Berkeley, the technical terms of physics are meaningful despite failing to designate any reality; their (...) meaningfulness derives from the useful role they play in organizing and predicting our experience. I argue that Berkeleian bodies have the same status as these theoretical entities: they are mere 'quasi-entities' introduced by our ways of speaking and thinking in order to serve our practical purposes. Berkeley nevertheless considers this to be a defense of the existence of bodies because he endorses a radically deflationary semantics for 'exists.'. (shrink)

Locke’s theory of consciousness is often appropriated as a forerunner of present-day Higher-Order Perception (HOP) theories, but not much is said about it beyond that. We offer an interpretation of Locke’s account of consciousness that portrays it as crucially different from current-day HOP theory, both in detail and in spirit. In this paper, it is argued that there are good historical and philosophical reasons to attribute to Locke the view not that conscious states are accompanied by higher-order perceptions, but rather (...) that conscious states constitute perceptions of themselves.

This entry outlines relationalism, primitivism, and eliminativism about color and considers objections to each theory.

Although the importance, both historically and systematically, of the seventeenth century distinction between primary and secondary qualities is commonly recognised, there is no consensus on its exact nature. Apparently, one of the main difficulties in its interpretation is to tell the constitutive from the argumentative elements. In this paper, we focus on the primary-secondary quality distinctions drawn by Boyle and Locke. We criticise, more specifically, MacIntosh’s analysis of them. On the one hand, MacIntosh attributes too many different primary-secondary quality distinctions (...) to Boyle and Locke. On the other hand, he forbears to attribute a particular primary-secondary quality distinction to them, which, at least in the case of Boyle, differs genuinely from his main distinction between the mechanical affections of matter and all of matter’s other qualities.

Locke's main semantic thesis is that words stand for, or signify, ideas. He says this over and over again, though the phraseology he employs varies. In Book III chapter 2 alone we find the following statements of the thesis: ‘ … Words … come to be made use of by Men, as the Signs of their Ideas’ [III.2.1; 405:10-11); The use then of Words, is to be sensible Marks of Ideas; and the Ideas they stand for, are their proper and (...) immediate Signification’ [III.2.1; 405:15-17]; ‘Words in their primary or immediate Signification, stand for nothing, but the Ideas in the Mind of him that uses them’ [III.2.2; 405:21-2]; That then which Words are the Marks of, are the Ideas of the Speaker’ [III.2.2; 405:27-8]; ‘ ….

When Keats identified truth and beauty, he surely intended mere extensionality. I myself have never had much trouble with either half of the equivalence. Others have considerable difficulty. A case in point is the Watson-Allaire-Cummins interpretation of Berkeley's idealism, which I shall refer to henceforth as the inherence account. That account is put forward to answer an extremely perplexing question in the history of philosophy: Why did Berkeley embrace idealism, i.e., why did he hold that esse est percipi, that to (...) be is to be perceived, indeed that what is perceived must be perceived in order to exist? In essence, the IA answers these questions very simply and elegantly: perceived qualities are, for Berkeley, qualities of the mind in the same sense that, in the tradition of substance metaphysics, blue is a quality of a blue flower; just as the blue of the flower is inseparable from it, so the perceived blue is inseparable from the mind that perceives it.

Berkeley’s capacity to conceive of mind-independent bodies was corrupted by his theory of representation. He thought that representation of things outside the mind depended on resemblance. Since ideas can resemble nothing than ideas, and all ideas are mind dependent, he concluded that we couldn’t form ideas of mind-independent bodies. More generally, he thought that we had no inner resembling proxies for mind-independent bodies, and so we couldn’t even form a notion of such things. Because conception is a suggestible faculty, Berkeley’s (...) arguments actually made it the case that he himself couldn’t conceive of mind-independent bodies. (shrink)
