Thought experiments involving The Matrix, brains-in-vats, or Cartesian demons have traditionally thought to describe skeptical possibilities. Chalmers has denied this, claiming that the simulations involved are real enough to at least sometimes defeat the skeptic. Through an examination of the meaning of kind terms in natural language I argue that, though the Chalmers view may be otherwise attractive, it is not an antidote to skepticism.

In chapter 1 of Reason, Truth, and History, Hilary Putnam argues from some plausible assumptions about the nature of reference to the conclusion that it is not possible that all sentient creatures are brains in a vat. If this argument is successful, it seemingly refutes an updated form of Cartesian skepticism concerning knowledge of physical objects. In this paper, I will state what I take to be the most promising interpretation of Putnam's argument. My reconstructed argument differs from (...) an argument strongly suggested by Putnam's text. I will show that the latter argument obviously does not work. The more promising argument which I reconstruct on behalf of Putnam raises some interesting questions about the relation between the contents of one's beliefs and one's environment and about how this relation affects the evaluation of anti-skeptical arguments. I conclude that my reconstructed argument ultimately fails as a response to Cartesian skepticism: the argument engenders a skepticism about knowledge of meaning, or propositional content, which undercuts its anti-skeptical force.

Most contemporary analytic philosophers of language and mind accept the view that there is a wide class of terms, “natural kind terms”, which includes names of substances (the most common example is “water”), of species of animals, and of many other kinds of things in nature, whose meaning and reference is determined in the way explained by the theory developed in the 1970s by Saul Kripke and Hilary Putnam. The theory is often referred to as “the Kripke-Putnam (...) theory” and is supposed to have such achievements as the overthrow of the earlier dominant Fregean theory of word-meanings (dubbed “descriptivism” by Kripke) as determined by the concepts in our minds, providing support for the “externalist” approach to linguistic meanings (in line with Putnam’s claim that “"Meanings" just ain’t in the head”), and the discovery that there is a wide class of truths (such as that water is H20) that are both a posteriori and necessary. Although the priority in the development of this theory belongs to Kripke, it could hardly gain such a wide acceptance without contributions by Putnam, which turned out to be very influential. However, the habitual idea of “the Kripke-Putnam theory”, as one theory, tends to play down the differences between Putnam’s and Kripke’s approaches and to hush up the fact that in his late works, of 1983 and 1990, Putnam revised and abandoned pretty much of his “Kripkean” views of 1970-ies; in particular, repudiated the pride of Kripke’s theory, the idea of necessary a posteriori truths. This article makes critical analysis and evaluation of Putnam’s ideas and arguments usually credited as important contributions to “the Kripke-Putnam theory”, and highlights the main points of the revision in late Putnam’s works. The case is made that Putnam's famous argument for externalism about meanings, the Twin-Earth thought experiment, is question-begging, fails to do justice to likely changes in the meanings of words with the development of knowledge, and conflicts with the linguistic practice in the relevantly similar case of “jade”. Putnam's argument for externalism from the division of linguistic labour is not cogent too, because “semantic deference” is itself a matter of what is there in “heads” - of some (non-expert) heads deferring to other (recognised as expert) heads. Eventually, on close inspection and in the light of Putnam's later reexplanation and revision, his account of meaning and reference turns out to be a sophisticated variety of conceptualism/internalism.

In "the meaning of 'meaning'," hilary putnam uses three "twin earth" examples to argue that natural kind terms do not have a sense. I argue that the first two only show that kind terms are like indexicals and that they are rigid designators but that this is compatible with having a sense. The third argument relies on a theory about the epistemological role of kind terms and the claim that there are no analytic (...) truths about kinds that could arise from a sense. (shrink)

This is a two tiered investigation. On the one hand, the author presents a systematic account of the philosophy of Hilary Putnam. Being the first comprehensive account to be published in the German-speaking world, the author traces the development of Putnam's realism and philosophy of language and their connections from the early 1950's to 2000. Contrary to the popular view of the discontinuity of Putnam's philosophy, he demonstrates that Putnam maintains certain semantic, pragmatic and epistemological foundations for the (...) rational confirmability, fallibility and self-corrigibility of theoretical knowledge in the empirical sciences as a constant around which many other philosophical assumptions are allowed to vary under critical examination. The resulting view of Putnam's philosophical "position" is decidedly "anti-metaphysical" (contrary to the common association of his philosophy of language with e.g. Kripke's understanding of realism), but not fully "deflationary" (contrary to the reclamation of his criticism of realist metaphysics as Quinean or Rortyan skepticism). On the other hand, the author generalizes, in the second and third parts of the book, Putnam's now famous theory of meaning and reference to develop a framework for the pragmatics of semantic continuity and discontinuity, as well as conceptual change within general terms in empirical settings, like natural kind terms, theoretical terms in natural sciences and commonsense classifications. The third part presents, develops and defends the basic normative premisses as a pragmatic alternative to both, metaphysical (Kripke, Devitt) and sceptical approaches (Quine, Kuhn). The main result here is that many (if not all) preconditions for the semantic bahvior of 'rigid' general terms are not, as usually assumed, ontological in nature, but can be usefully framed as part of the pragmatics of general terms in epistemic practices counting with rational revisability.

Following the influential thought experiments by Hilary Putnam and others, philosophers of language have for the most part adopted semantic externalism concerning natural kind terms. In this article, we present results from three experiments on the reference of natural kind terms. Our results confirm some standard externalist assumptions, but are in conflict with others: Ordinary speakers take both appearance and underlying nature to be central in their categorization judgments. Moreover, our results indicate that speakers’ categorization (...) judgments are gradual, and proportional to the degree of similarity between new samples and familiar, “standard” samples. These findings pose problems for traditional theories, both externalist and internalist. (shrink)

Many still seem confident that the kind of semantic theory Putnam once proposed for natural kind terms is right. This paper seeks to show that this confidence is misplaced because the general idea underlying the theory is incoherent. Consequently, the theory must be rejected prior to any consideration of its epistemological, ontological or metaphysical acceptability. Part I sets the stage by showing that falsehoods, indeed absurdities, follow from the theory when one deliberately suspends certain devices Putnam (...) built into it , presumably in order to block such entailments. Part II then raises the decisive issue of at what cost these devices do the job they need to do. It argues that - apart from possessing no other motivation than their capacity to block the consequences derived in Part I - they only fulfil this blocking function if they render the theory unable to deal with fiction and related 'make-believe' activities. Part III indicates the affinity Putnam's account has with the classically 'denotative' view of meaning, and thus how its weaknesses may be seen as a variant of the classical weakness of 'denotative' approaches. It concludes that the theory is a conceptual muddle. (shrink)

In this chapter, the author says that the standard view of brain‐in‐a‐vat scenario is endorsed by the people who created The Matrix. The author argues that the hypothesis that he is envatted is not a skeptical hypothesis, but a metaphysical hypothesis. That is, it is a hypothesis about the underlying nature of reality. According to the author, the Matrix Hypothesis is equivalent to a version of the following three‐part Metaphysical Hypothesis. First, physical processes are fundamentally computational. Second, our cognitive systems (...) are separate from physical processes, but interact with these processes. Third, physical reality was created by beings outside physical space‐time. The Metaphysical Hypothesis combines the Creation Hypothesis, the Computational Hypothesis, and the Mind‐Body Hypothesis. It also adds a more specific claim: the computational processes underlying physical space‐time were designed by the creators as a computer simulation of a world. (shrink)

A natural way to think about epistemic possibility is as follows. When it is epistemically possible (for a subject) that p, there is an epistemically possible scenario (for that subject) in which p. The epistemic scenarios together constitute epistemic space. It is surprisingly difficult to make the intuitive picture precise. What sort of possibilities are we dealing with here? In particular, what is a scenario? And what is the relationship between scenarios and items of knowledge and belief? This (...) chapter tries to make sense of epistemic space. It explores different ways of making sense of scenarios and of their relationship to thought and language. It discusses some issues that arise and outlines some applications to the analysis of the content of thought and the meaning of language. (shrink)

First published in 1978, this reissue presents a seminal philosophical work by professor Putnam, in which he puts forward a conception of knowledge which makes ethics, practical knowledge and non-mathematic parts of the social sciences just as much parts of 'knowledge' as the sciences themselves. He also rejects the idea that knowledge can be demarcated from non-knowledge by the fact that the former alone adheres to 'the scientific method'. The first part of the book consists of Professor Putnam's John Locke (...) lectures, delivered at the University of Oxford in 1976, offering a detailed examination of a 'physicalist' theory of reference against a background of the works of Tarski, Carnap, Popper, Hempel and Kant. The analysis then extends to notions of truth, the character of linguistic enquiry and social scientific enquiry in general, interconnecting with the great metaphysical problem of realism, the nature of language and reference, and the character of ourselves.

Some philosophical proposals seem to die hard. In a recent paper, Jason Stanley has worked to resurrect the description theory of reference, at least as it might apply to natural kind terms like ‘elm’ (Stanley, 1999). The theory’s founding idea is that to understand ‘elm’ one must know a uniquely identifying truth about elms. Famously, Hilary Putnam showed that ordinary users of ‘elm’ may understand it while lacking such knowledge, and may even be unable to distinguish elms (...) from beeches (Putnam, 1975). In response, Stanley claims that linguistic understanding in the case of natural kind terms comes in levels, and that only those at the top level need have the knowledge in question. The description theory, in Stanley’s hands, applies only to those with top level understanding and it is their understanding that fixes the term’s reference. To use the term successfully, those with inferior understanding need only be defer- ential to those at the top. However, Stanley’s appeal to expert knowledge fails to revive the description theory.

The scenario of the brain in a vat, first aired thirty-five years ago in Hilary Putnam's classic paper, has been deeply influential in philosophy of mind and language, epistemology, and metaphysics. This collection of new essays examines the scenario and its philosophical ramifications and applications, as well as the challenges which it has faced. The essays review historical applications of the brain-in-a-vat scenario and consider its impact on contemporary debates. They explore a diverse range of philosophical issues, from intentionality, (...) external-world scepticism, and the nature of truth, to the extended mind hypothesis, reference magnetism, and new versions of realism. The volume will be a rich and valuable resource for advanced students in metaphysics, epistemology, and philosophy of mind and language, as well as anyone interested in the relations between language, thought and the world.

Since Hilary Putnam and Saul Kripke's first attacks on traditional, descriptivist theories of natural kind terms, it has become customary to speak of the ‘Putnam-Kripke’ view of meaning and reference. This article argues that this is a mistake, and that Putnam's account of natural kind terms is importantly different from that of Kripke. In particular, Putnam has from the very start been sceptical of Kripke's modal claims, and in later papers he explicitly rejects the proposal (...) that theoretical identity statements are metaphysically necessary (if true). I suggest that this is wholly in line with Putnam's earlier, Quine-inspired writings on general terms, and his preoccupation with the philosophy of science. Moreover, I argue that the picture of general terms that emerges from Putnam's writings is more plausible than that suggested by Kripke. However, contrary to Putnam, I also suggest that Putnam's later views on natural kinds and natural kind terms do not support standard Twin Earth externalism. (shrink)

The argument that has inspired much of the recent discussion of the logical relationship between these views is found in Putnam : If externalism is true, then if S were a brain in a vat, S’s utterances of the sentence “I am a brain in a vat” would not express the proposition that S is a brain in a vat. S’s use of the words “brain” and “vat” would not refer to a real brain or vat, just as, in a (...) Twin Earth-style thought experiment, the Twin Earthling cannot refer to water with his use of the term “water.” If we accept that generally we have knowledge of the contents of our utterances, then, if S knows that her utterances of “brain” and “vat” mean brain and vat, it will be possible for S to know that she is not a brain in a vat. For if S has authority with respect to the contents of her utterances, then she can know that her utterance, “I am not a brain in a vat,” refers to brains and vats. On externalism, since S would not refer to brains and vats if she were a brain in a vat, she could know by mere introspection that she is not a brain in a vat. In fact, S can come to know many arbitrary propositions about the external world simply by attending to the contents of her thoughts. For if externalism is true, she can argue, then certain empirical conditions must be satisfied if she is even to have the thoughts about the external world that she does; since she knows what she is thinking, she knows these empirical conditions are satisfied. Thus, if S knows that she is thinking about brains and vats, then she can know that she is not a brain in a vat ; for if she was a BIV, then she would not be thinking about brains and vats, but instead about electrical impulses or some such thing. The standard BIV argument against scepticism, therefore, cannot be correct. This line of argument can then be used to conclude more generally that scepticism is false; for the argument can be run with virtually any utterance or thought with empirical content. If S knows that she is thinking about trees, for example, then she can know that there are trees. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Worst Case of Knowing the Other?Stanley Cavell and Troilus and CressidaDavid HillmanStanley Cavell's luminous and influential writings about Shakespeare's works include extended essays on seven of the plays, and, scattered throughout his writings, more casual passages on many of the others. He takes these works to be significantly engaged in the conditions of skepticism as he apprehends it. These plays, according to Cavell, wrestle profoundly with questions about (...) the origins of, and the possibilities of living with, skeptical ways of thinking.Troilus and Cressida is Shakespeare's most self-consciously philosophical play, and the place in the Shakespearean corpus where the relations between philosophy and literature are most openly and directly addressed. It is often referred to as a "skeptical satire," and considered to be a kind of prelude to the great tragedies of the first decade of the seventeenth century. As I intend to show, in practically all of its salient features the play exhibits precise and—to my mind—unmistakable versions of many of the most significant features of skepticism as illuminated by the work of Cavell.Heinrich Heine, rather astonishingly, declared that Troilus and Cressida was "Shakespeare's most characteristic creation"; "for a detailed judgement," he added, "we should need the help of that new aesthetics which has not yet been written."1 I suggest that Cavell's aesthetics might go some way to remedying the absence Heine identifies. To my knowledge, though, there is not a single reference to the play—and certainly no extended discussion—throughout the writings of Cavell, and this strikes me as something of a mystery; for Troilus and Cressida appears to present opportunities to exemplify with particular clarity the lineaments of skepticism Cavell finds elsewhere writ large in the [End Page 74] Shakespearean corpus. And I think the play also offers possibilities for extending these investigations in unexplored directions, perhaps towards the origins of Shakespeare's engrossment with skeptical problems, perhaps towards the delicate question of the borderline between skepticism and cynicism, or the relation between, say, Montaignean skepticism (which Cavell describes as asking "how to conduct oneself best in an uncertain world") and Cartesian skepticism ("how to live at all in a groundless world")2—questions I intend to open rather than trying to answer here. In a word, if one is going to write about the claims of reason in Shakespeare, overlooking the play where the word "reason" appears significantly more often than in any other play (21 times according to the Harvard Shakespeare Concordance) seems like a peculiar thing to do. It is of course possible that the play has simply, as it were, not found an opportunity to impress itself upon the attention of Cavell, more or less by happenstance; if so, one aim of this paper is, quite simply, to remedy that oversight. More impertinently, but also more interestingly—and, perhaps, in a more Cavellian manner—I will be prompted to contemplate towards the end of this paper the possibility that there may perhaps be some knowledge being disowned in the occlusion of this play from Cavell's writing.I begin, by way of prologue, with a short rumination about my title, which has had a tendency to oscillate in my mind between "the worst case of the other" and "the worst case of knowing the other"; this uncertainty has something to do with, precisely, the question of the relation between cynicism and the attempt to deny skepticism—that is, between assuming the worst about another, and assuming one knows anything at all about the other—as if to say, if that's (epistemologically) the worst I can do, well, at least I know something, however unsavory or reductive it may be; perhaps the play's best-known phrase, "One touch of nature makes the whole world kin" (3.3.175), reveals just how disturbing its vision is.3 For the phrase has often been taken out of context and made to mean something rather idealizing, as if it refers to the natural affinity or humanity of us all; its actual meaning, made clear by the following line ("That all with one consent praise new-born gauds"), is far...

Names and natural kind terms have long been a major focus of debates about meaning and reference. This article discusses some of the theories and arguments that have appeared in those debates. It is remarkably difficult to say what names are without making controversial theoretical assumptions. This article does not attempt to do so here. It instead relies on paradigm examples that nearly all theorists would agree are proper names, for instance, ‘Aristotle’, ‘Mark Twain’, ‘London’, ‘Venus’, and ‘Pegasus’. (...) All of the proper names that are discussed in the article are singular nouns that have no syntactic structure. Most of them refer to objects, but some, such as ‘Pegasus’, apparently do not. The article begins with proper names and the question ‘What is the meaning of a proper name?’ It turns to natural kind terms later. (shrink)

Aristotle's account of the meaning of natural kind terms and the essence of natural kinds is distinguished from that offered by Saul Kripke and Hilary Putnam. With regard to, Aristotle did not require that one who understands a natural kind term and goes on to discover the essence of the kind grasps at the outset that the kind exists or has an essence yet to be discovered. With regard to, Aristotle separates essences (...) from necessary properties and connects essences with definition and explanation. is discussed in Part I of the book, in Part II. While the book contains detailed exegesis of Aristotle's text, it also includes a trail for readers mainly interested in grasping his overall philosophical picture. (shrink)

SCIENTISTS HAVE DISCOVERED that water is H2O. Water is H2O is true. But is it a necessary truth? In other words, is it true in all possible worlds? Some people think it is. For example Hilary Putnam, in his well-known Twin Earth argument, concludes that "water is H2O" is necessarily true; thus a liquid which phenomenally resembles H2O and fits the description of water in almost all aspects, but has the chemical formula XYZ, cannot be water. Saul Kripke (...) has made a similar claim about the necessary identity between water and H2O. Because this type of truth is based on empirical discoveries, Kripke calls truths of this sort "necessary a posteriori." The thesis shared by Putnam and Kripke has two premises: a realist view that natural kinds exist independently of human cognition, and a theory of direct reference of natural kind terms. Opposing the view that natural kind terms pick out objects through descriptions, Putnam and Kripke hold that natural kind terms pick out natural kinds in the world in a direct way. Based on these two premises, they argue that, if two natural kind terms, A and B, designate the same thing in the world, "A = B" expresses a necessary identity. (shrink)

The present paper focuses on essentialism about natural kinds as a case study in order to illustrate this more general point. Saul Kripke and Hilary Putnam famously argued that natural kinds have essences, which are discovered by science, and which determine the extensions of our natural kind terms and concepts. This line of thought has been enormously influential in philosophy, and is often taken to have been established beyond doubt. The argument for the conclusion, however, (...) makes critical use of intuitions, and I note that the intuitions are of the sort had by preschool children, and that they are traceable to a deep-seated cognitive outlook, which is often called “psychological essentialism.” Further, if we did not have such a cognitive outlook or implicit belief set—a belief set which is in fact in place by at least age 4—then we would not have the relevant philosophical intuitions. In light of this, I consider the question of whether natural kinds actually have scientifically discovered or discoverable essences, and whether these putative essences could determine the extensions of our terms and concepts as Kripke, Putnam, and many others have supposed. In fact, a number of philosophers of biology and chemistry have argued that biological and chemical kinds do not have such essences, yet these arguments—particularly in the case of chemistry—have not been assimilated by philosophers more generally. The reason for this poor assimilation is, I suggest, that the Kripke/Putnam view is just so intuitive. But this fact, I argue, is due to a deep-seated cognitive bias, rather than to any special insight into the nature of reality. (shrink)

The dissertation critically examines Husserl's transcendental idealism as a response to epistemological skepticism. Contrary to prevailing interpretations, I argue that Husserl intended to formulate a non-reductive, idealist justification of empirical knowledge. I take the standard phenomenalistic interpretation of Husserl's idealism to be right in discerning his basic concern with the refutation of skepticism, but wrong in construing the transcendental reduction as an ontological reduction of the natural world to "ideal" sets of transcendental experiences. On the other hand, recent (...) "neutrality views" which hold that phenomenological epoche requires the permanent suspension of ontological commitments seem to confuse Husserl's quasi-verificationist critique of traditional metaphysics with the positivistic critique of all metaphysics. I suggest instead that Husserl's epistemological program be understood as an attempt to ground transcendentally, i.e. on the basis of apodictic and presuppositionless evidences, our ordinary beliefs about the world. In this light, Husserl's Weltvernichtung argument for the presuppositionlessness of consciousness can be seen as a necessary precondition of the transcendental justification of empirical knowledge. ;To clarify Husserl's genetic phenomenology, I adopt Dagfinn Follesdal's interpretation of the noema as a Fregean Sinn. I distinguish two levels of 'constitution' to show how Husserl traces back the sense and being of the objective world to the synthetic activity of the transcendental subject. The resolution of transcendental analogues of skeptical doubts by means of Husserl's analysis of 'retroactive cancellation' completes, in general outline, the grounding of the "verificationism" of the natural attitude. However, I argue that the anti-skeptical force of 'retroactive cancellation' depends on conceiving the relationship between the conscious subject and the world in a way that renders Weltvernichtung unintelligible. Husserl's transcendental idealist response to the skeptic accordingly leads to a dilemma: either one maintains the presuppositionlessness of consciousness but abandons the critique of skepticism for a descriptive study of the transcendental structures of experience; or one attempts to reformulate Husserl's phenomenological verificationism while abandoning the goal of absolute grounding.

The Matrix presents a version of an old philosophical fable: the brain in a vat. A disembodied brain is floating in a vat, inside a scientist’s laboratory. The scientist has arranged that the brain will be stimulated with the same sort of inputs that a normal embodied brain receives. To do this, the brain is connected to a giant computer simulation of a world. The simulation determines which inputs the brain receives. When the brain produces outputs, these are fed back (...) into the simulation. The internal state of the brain is just like that of a normal brain, despite the fact that it lacks a body. From the brain’s point of view, things seem very much as they seem to you and me. (shrink)

Naturalists who conceive of knowledge as a natural kind are led to treat ‘knowledge’ as a natural kind term. ‘Knowledge,’ then, must behave semantically in the ways that seem to support a direct reference theory for other natural kind terms. A direct reference theory for ‘knowledge,’ however, appears to leave open too many possibilities about the identity of knowledge. Intuitively, states of belief count as knowledge only if they meet epistemic criteria, not merely (...) if they bear a causal/historical relation to the term. I will develop this objection and show that it is grounded in modal considerations central to Kripke’s work on reference. I will also argue that a more plausible externalist semantics for natural kind terms disarms the objection. (shrink)

"Twin earth" examples have motivated a number of proposals for the lexicography of kind terms in natural languages. It is argued that these proposals create unacceptable difficulties for the analysis of de dicto propositional attitudes. A conservative solution of the twin earth problems is then proposed according to which they reflect pragmatic features of language use rather than semantic features of lexical content.

In today’s America the persistence of crushing poverty in the midst of staggering affluence no longer incites the righteous jeremiads it once did. Resigned acceptance of this paradox is fueled by a sense that poverty lies beyond the moral and technical scope of government remediation. The failure of experts to reach agreement on the causes of poverty merely exacerbates our despair. Are the causes internal to the poor – reflecting their more or less voluntary choices? Or do they emanate from (...) structures beyond their control? If both of these explanations are true, poverty experts will need to shift their focus to a hitherto under-theorized concept: coercion. I defend this claim by appealing to distinct areas of philosophical inquiry: social epistemology and moral theory. Poverty knowledge is directly related to both of these inquiries. The aim of poverty knowledge is clearly moral: to reduce suffering and to empower the weak. While the former aim is grounded in utilitarian thinking, the latter aim is grounded in the social contractarian insight that poverty is unjustly coercive, imposing excessive limits on the opportunities and choices of the poor that render them vulnerable to domination by others. Equally obvious is the social nature of poverty knowledge. All knowledge depends on the reliable testimony of others. Poverty knowledge not only ostensibly offers us the most reliable, scientific beliefs about the causes and effects of poverty, thereby determining how we morally judge the poor and their poverty, but it reciprocally bases its understanding of poverty on what the poor themselves have to say about it. What unites both social epistemology and moral theory – at least the social contract variants I will be examining here – is concern about the limits and possibilities of rational choice. As poverty knowledge came of age in the fifties and sixties, it absorbed the language of rational choice prevalent in economics, especially the Keynesian economics whose moral underpinnings can be found in Rawlsian social contract theory. Echoing a different economic theory supported by a different, more libertarian, brand of social contract theory, poverty expertise in the eighties continued to use an abstract model of rational choice. I submit that, in both early and later epochs of poverty expertise, reliance on rational choice reasoning prevented poverty experts from appreciating the coercive impact of poverty on the poor. Social epistemology explains this failure by demonstrating the poverty of rational choice thinking and its mistaken reliance on inflated commonsense expectations about the capacity of individuals to calculate their long-term interests, free from the distortions of social bias. Social epistemology not only exhibits the dangers of not relying on expert testimony, but it also exhibits the dangers of relying on an unreliable source of expert testimony that has removed itself from its human subject matter. In order for poverty experts to become more reliable educators about poverty’s coercive impact on the poor they must return to their discipline’s social epistemological roots. Only a more descriptive and explanatory sociology can narrate a comprehensive story about how the lived experience of poverty relates to the larger social system. The social contractarian model best suited to underwriting this kind of poverty knowledge, I submit, is the discourse theoretic model that has been championed by Jürgen Habermas. When applied as a pedagogical method of dialog and not as a social contractarian model of rational normative consent, discourse theory highlights the unique epistemological advantages of empathetic understanding that are so essential to dispelling stereotypes about the poor. Dispelling these stereotypes is the first step toward respecting the poor as free agents who are nonetheless forced to make suboptimal choices. My defense of these claims proceeds as follows: Part One argues that poverty expertise rightly deserves the opprobrium critics have heaped on it. The charge – leveled by progressives and conservatives alike - that such expertise is ideological is true to the extent that poverty knowledge has all-too-easily accommodated the political aims of the agency that has funded it: the federal government. The shift from the war on poverty to the war on the poor – and the resulting shift from blaming poverty on economic structures to blaming it on the culture of poverty – would not have been possible without an increased emphasis on data gathering aimed at measuring poverty rather than describing it. Part Two assesses the consequences of turning away from qualitative research to statistical analysis: the coercive nature of poverty becomes invisible beneath the surface of aggregate individual choices. The failure to grasp how voluntary choices, ostensibly based on rational, self-interested calculations, can be coerced by social structures - and thereby lead to sub-optimizing behavior – invites the conclusion that the poor have only themselves to blame for their misery. Part Three suggests that this pathologization of the poor directly controverts the major aim of poverty research: to empower the poor as free and equal parties to the social contract. I argue that the different varieties of social contract theory that have justified poverty expertise over the last forty years – the welfarist model pioneered by Rawls and the market-based model defended by Nozick – embrace the same rational choice models favored by poverty experts and so conspire with the latter in neglecting important dimensions of poverty-related coercion. While the welfarist model conceals the coercive nature of bureaucratically administered entitlement programs and top-down urban renewal policies, the market-based model conceals the coercive nature of economic class structures. The discourse-theoretic alternative proposed by Habermas endorses a populist, democratic response to the overly abstract rational choice assumptions embedded in these other models. Despite this advance over its counterparts, the chief advantage of discourse theory for poverty knowledge, I submit, resides less in its proposed procedure of rational collective choice than in its heuristic as a dialogical method of social learning. I demonstrate this claim in Part Four, where I turn to the social epistemological insights of Allen Buchanan. Social epistemology offers a much needed corrective to theories of knowledge that rely on the reasoning capacities of isolated individuals. By stressing the connection between moral response and social belief, on one hand, and the dependence of social belief on epistemic authorities, on the other, social epistemologists suggest ways in which we can learn to distinguish reliable from unreliable authorities and become aware of our own error-prone cognitive proclivities. Their insights need to be supplemented by moral epistemologists who stress the affective dimension of knowledge, above all, the role that empathy plays in understanding the plight of others. Drawing from victim narratives, Diana Meyers shows that switching between first-person experiences of one's own and third-person reconstructions of others' experiences is essential to appreciating the gravity of human rights violations and the seriousness of human rights claims. It goes without saying that such empathy is just as essential to understanding the plight of the poor. Meyers mainly has in mind empathetic understanding that has been facilitated by third-person observation and literary encounter, but the importance of visceral and corporeal representation suggests that face-to-face dialog may sometimes be a more effective way to facilitate empathetic understanding.

Modern skepticism can be usefully divided into two camps: the Cartesian and the Humean.1 Cartesian skepticism is a matter of a theoretical doubt that has little or no practical import in our everyday lives. Its employment concerns whether or not we can achieve a special kind of certain knowledge – something Descartes calls “scientia” 2—that is far removed from our everyday aims or standards of epistemic appraisal. Alternatively, Humean skepticism engages the ancient skeptical concern with whether we have good (...) reason, or any reason at all, for our beliefs, including the common or garden beliefs that are presupposed in our ordinary practical affairs. On this traditional conception, philosophical doubt is a projection of everyday doubt and the lessons of the study are potentially lessons for the street. In this paper I shall focus on the Humean strain of skepticism whose focus concerns whether we have adequate reasons for our beliefs. Henceforth when I speak of skepticism it is this variety of skepticism that I am primarily referring to.3 I want to relate skepticism, so understood, to two kinds of self-knowledge. I shall argue that the failure of past solutions and dissolutions of skepticism to provide a satisfying response to the skeptic can be accounted for in terms of two stances that we can take towards our own..

In this chapter, I argue that it is time for an applied turn in epistemology analogous to the applied turn in ethics of the 1970s. Our epistemic landscape is changing rapidly. For example, the rise of new technologies, such as mobile phones and the internet, along with the decline of older sources of information, such as newspapers and traditional reference books, have significantly changed the ways in which we acquire knowledge and justify our beliefs. Philosophers, and especially epistemologists, should be (...) engaging in contemporary debates about these changes. The “knowledge economy” and the “information society” cry out for a new approach to epistemology. To some extent, the applied turn in epistemology is already underway. Although the term “applied epistemology” doesn't have the kind of brand recognition that “applied ethics” does, in recent years, several philosophers, some of whom are represented in this book, have explicitly applied epistemic considerations to issues of contemporary concern. Much of this has been categorised as “social epistemology”, rather than “applied epistemology”. Although the concerns of social epistemology and applied epistemology overlap to a great extent, they should be distinguished. Not all social epistemology is particularly applied and not all applied epistemology is particularly social. (shrink)

According to epistemological disjunctivism (ED), ordinary perceptual experience ensures an opportunity for perceptual knowledge. In recent years, two distinct models of this idea have been developed. For Duncan Pritchard (Epistemological disjunctivism, 2012, Oxford University Press; Epistemic angst: Radical skepticism and the groundlessness of our believing, 2012, Princeton University Press), perception provides distinctly powerful reasons for belief. By contrast, Clayton Littlejohn (Journal of Philosophical Research, 41, 201; Knowledge first, 2017, Oxford University Press; Normativity: Epistemic and practical, 2018, Oxford (...) University Press) and Alan Millar (The nature and value of knowledge: Three investigations, 2010, Oxford University Press; Philosophical Issues, 21, 332) argue for a version of ED in terms of a “knowledge first” program, on which perception directly provides knowledge, without relying on antecedent reasons or justification. Specifically, both Littlejohn and Millar argue that “reasons first” ED faces a problematic regress. In this article, I defend “reasons first” ED by arguing that experience provides a type of reason that escapes the regress. I also argue that reasons are a fundamental aspect of ED, especially in its anti-skeptical stance. (shrink)

Cartesian arguments for global skepticism about the external world start from the premise that we cannot know that we are not in a Cartesian scenario such as an evil-demon scenario, and infer that because most of our empirical beliefs are false in such a scenario, these beliefs do not constitute knowledge. Veridicalist responses to global skepticism respond that arguments fail because in Cartesian scenarios, many or most of our empirical beliefs are true. Some veridicalist responses have been motivated using verificationism, (...) externalism, and coherentism. I argue that a more powerful veridicalist response to global skepticism can be motivated by structuralism, on which physical entities are understood as those that play a certain structural role. I develop the structuralist response and address objections. (shrink)

The Moral Twin Earth challenge to ethical naturalism threatens to undermine an otherwise promising metaethical view by showing that typical, naturalist-friendly theories of reference determination predict diverging reference in Twin Earth scenarios, making it difficult to account for substantive moral disagreement. Several theorists have recently invoked David Lewis’s doctrine of reference magnetism as a solution, claiming that a highly elite moral property—a moral “joint in nature”—could secure shared reference between ourselves and our twins on Twin Earth, (...) despite our diverging usages of moral terms. This paper argues that this move has significant methodological implications: namely, it entails that a certain sort of simplicity is truth-conducive. Consequently, when applied to moral theories, this gives certain views, specifically monist ones like utilitarianism and contractualism, an advantage over their more complicated rivals, forms of pluralism and particularism. Thus, ethical naturalists cannot invoke reference magnetism without a substantial impact on first-order theorizing. (shrink)

This collection of 16 original articles by prominent theorists from a variety of disciplines provides an excellent insight into current thinking about artifacts. The four sections address issues concerning the metaphysics of artifacts, the nature and cognitive development of artifact concepts, and the place of artifacts in evolutionary history. The most overtly philosophical contributions are in the first two sections. Metaphysical issues addressed include the ‘mind-dependence’ of artifacts and the bearing of this on their ‘real’ existence, and the distinction between (...) natural and artifact kinds, and its implications for issues in epistemology and semantics – for example, whether there is ‘maker's knowledge’ of artifacts, and whether ‘direct’ theories of reference apply to artifact-kind terms. The papers concerned with the nature of artifact concepts – the ways in which we represent artifacts to ourselves – address how judgements of artifact identity track judgements about manifest appearance, function, and maker's intentions, and the neuroscientific basis for artifact categorization.

In lieu of an abstract, here is a brief excerpt of the content:Ernst Cassirer, Historian of the WillDavid A. Wisner‘Tis not Wit merely, but a Temper, which must form a Well-Bred Man. In the same manner, ‘tis not a Head merely, but a Heart and a Resolution which must compleate the real Philosopher. 1In order to possess the world of culture we must incessantly reconquer it by historical recollection. But recollection does not mean merely the act of reproduction. It is (...) a new intellectual synthesis—a constructive act.... History is not knowledge of external facts or events; it is a form... an organon of our self-knowledge, an indispensable instrument for building up our human universe. 2Ernst Cassirer is probably best known to historians of ideas for his work on the problem of knowledge, which began with a neo-Kantian historical analysis of epistemological questions and culminated in the philosophy of symbolic forms. As he himself always admitted, even in his last public writings, this focus on epistemology was the foundation of his philosophical interests. Yet by the last two decades of his life he had in true Socratic fashion endowed his investigations with heightened emphasis. “That self-knowledge is the highest aim of philosophical inquiry,” he wrote in the opening lines of An Essay on Man, “appears to be generally acknowledged.” 3 Cassirer perceived, however, [End Page 145] that the need for such an effort to be made had reached monumentally critical proportions: the early twentieth century had engendered grave historical and philosophical crises which threatened to reverse the progress of modern thought. Paradoxically, modern philosophy had many tools for attaining “knowledge of human nature” and yet stood farther from its goal than ever before. What Cassirer called “anthropological philosophy,” concerned as it was “with the whole destiny of man,” still required special consideration, in both its theoretical and its historical dimensions. 4 It was essentially to these twin domains that Cassirer would devote himself in his later years.The transformation of Cassirer’s philosophical perspectives thus had two facets. In order to outline his program Cassirer had first to consider a broader range of human activities than thought alone, from which he concluded that human culture consisted of a hierarchy of symbolic forms beginning with myth and culminating in science. However, he also felt compelled to elucidate the historical process by which these symbolic forms could progressively manifest themselves, and more specifically the individual human effort which was required for true self-knowledge. This he did principally in his historical works of the late 1920s and early 1930s, and with particularly profound results: from a historian of knowledge Cassirer became a historian of the will; from an epistemologist he became an ethical thinker; from an academic he became an exemplar of self-conscious moral action, a paragon of human autonomy and freedom. Indeed, in this endeavor he proved to be more thoroughly and fundamentally a Kantian than ever his theory of knowledge would reveal.I would go so far as to suggest that Cassirer’s history of the will was an integral part of his mature constructive philosophy. On the surface this history can be restated in the following terms. First, Cassirer insists on a fundamental opposition between the rationalism and intellectualism of ancient Greek philosophy and the voluntarism of the Judeo-Christian tradition, both of which represent in Cassirer’s view manifestations of a struggle in Western thought continuing well into the twentieth century. Second, he suggests that the historical task of Western philosophy since the first mature articulation of Latin Christian theology by Saint Augustine has been to liberate the individual human will from any and all forms of subservience. Such views are most forcefully expressed in The Myth of the State, Cassirer’s last book, but they actually constitute an essential and coherent element in all of Cassirer’s later work on the history of ideas and culture. Indeed, Cassirer’s history of the will provides us with a particularly keen and nuanced account of this essential Western legacy, while at the same time reading into it in Kantian manner a moral for the life of the individual human being.

Available from UMI in association with The British Library. Requires signed TDF. ;This work examines some of the epistemological and ontological conditions of the deep self-knowledge that is demanded by the Delphic motto gnothi seauton . The guiding questions are: what is the 'self' that deep self-knowledge is of? What are we such that we can ask deep and puzzling questions about our life-plans, our self-conceptions and the meaning of our lives? Can we know ourselves as we really are, (...) or only under a certain description which conceals as much as it reveals? What is the nature of the relation between self-knowledge and reality? ;The central thesis that is defended is that a person is to a certain extent a self-defining and self-forming being by virtue of his self-knowledge; fundamental changes in how he knows himself, and conceives his way of life, his life-history, emotions, final ends, death etc.--particularly in light of fundamental practical questions --necessarily occasion changes in what he is. What he is at any one moment in his life is in part constituted by his self-knowledge. ;To account for the complex 'inter-relation' between self-knowledge and its object, and the possibility of self-formation, a broadly Kantian theory of constituting activity is developed, as well as a theory of the empirical 'under-determination' of self-knowledge. The peculiarity of self-knowledge is that the knower is the known, and that he is active with respect to the object known ; the object of knowledge and the knowing subject change and extend their range together. This complicates some of the claims of realism and the correspondence theory of truth: self-knowledge is not a matter of the strict conformity of beliefs or conceptions to an independent, determinate and unchanging reality. In Kantian terms, the object of self-knowledge conforms to the conditions of knowledge. ;This broadly Kantian approach is brought to the analysis of Hampshire and Sartre's theories, which are studied as illustrations of the general ontological and epistemological conditions of self-knowledge. Other issues that are discussed include the problem of truth conditions in deep self-knowledge, the agent-observer dualism in self-inquiry, the relational model of the self, and Iris Murdoch's critique of Hampshire and Sartre.

Inspired by Rudolf Carnap's Der Logische Aufbau Der Welt, David J. Chalmers argues that the world can be constructed from a few basic elements. He develops a scrutability thesis saying that all truths about the world can be derived from basic truths and ideal reasoning. This thesis leads to many philosophical consequences: a broadly Fregean approach to meaning, an internalist approach to the contents of thought, and a reply to W. V. Quine's arguments against the analytic and the a (...) priori. Chalmers also uses scrutability to analyze the unity of science, to defend a conceptual approach to metaphysics, and to mount a structuralist response to skepticism. Based on the 2010 John Locke lectures, Constructing the World opens up debate on central philosophical issues involving language, consciousness, knowledge, and reality. This major work by a leading philosopher will appeal to philosophers in all areas. This entry contains uncorrected proofs of front matter, chapter 1, and first excursus. (shrink)

This paper considers the problem of assigning meanings to empty natural kind terms. It does so in the context of the Twin-Earth externalist-internalist debate about whether the meanings of natural kind terms are individuated by the external physical environment of the speakers using these terms. The paper clarifies and outlines the different ways in which meanings could be assigned to empty natural kind terms. And it argues that externalists do not have the semantic (...) resources to assign them meanings. The paper ends on a sceptical note concerning the fruitfulness of using the Twin-Earth setting in debates about the semantics of empty natural kind terms. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The American Philosopher: Conversations with Quine, Davidson, Putnam, Nozick, Danto, Rorty, Cavell, MacIntyre, and KuhnDavid GormanThe American Philosopher: Conversations with Quine, Davidson, Putnam, Nozick, Danto, Rorty, Cavell, MacIntyre, and Kuhn, by Giovanna Borradori; translated by Rosanna Crocitto; xii & 177pp. Chicago: University of Chicago Press, 1993, $32.00 cloth, $12.95 paper.The idea for this book, first published in Italian in 1991, was good—to assemble a collection of interviews with (...) the key figures in American philosophy. And the list of philosophers whom Giovanna Borradori chose as representing the best in contemporary American thought was very good—as becomes especially clear when in her introduction she mentions the ones who, for whatever reason, got away: Noam Chomsky, Jerry Fodor, Nelson Goodman, Saul Kripke, John Rawls, and John Searle (p. 5). Add these names to those of the philosophers whom she was able to interview for this volume, and you have an impressively complete roster of the thinkers who have made the postwar era in the United States arguably one of the great periods of philosophy.Unfortunately, the execution of the book does not fulfill the promise of its conception. And perhaps nothing could have; the fact remains, however, that Borradori proves herself singularly ill-equipped, in terms both of background knowledge and of intellectual orientation, to bring out very much of importance in these important philosophers’ ideas, either in the interviews that she conducts with them or in the prefatory material that she supplies to bind the collection together.The essence of Borradori’s problem is that she approaches these professional academic philosophers with the incongruous assumption that they are [End Page 388] people with interesting general ideas about history, society, art, religion, or whatever—she assumes in short that these professors are intellectuals. But that is scarcely a term that describes your typical American philosopher. Nor do I mean this condescendingly: on the contrary, just what is significant and valuable about contemporary philosophers in the analytic mold (as almost all of Borradori’s interviewees are) is the narrowness of their focus on problems and methods of logic and the natural sciences, the two Archimedean levers by which analytic philosophy has come far closer than anyone could have predicted to moving the conceptual universe decisively.Of course, not everyone views matters this way, and Richard Rorty in particular has made a spectacular career out of disputing this image—largely a self-congratulatory one, as he takes it—of the analytic tradition. Whether his dissent is justified or not, his role in the collection constitutes another of its problems, because he is not just one of the group of thinkers whom Borradori is interviewing: beyond this, it is Rorty’s ideas which supply Borradori with an intellectual program (in default of one of her own), which necessarily distorts her presentation of the other philosophers’ thoughts, and her line of questioning in these interviews. So, for example, all the interviewees are subjected to questions about American Pragmatism generally and John Dewey in particular, not because these things are of any inherent significance to most of them (as several of them point out, politely), but because Rorty thinks that they should be, and because Borradori follows his line unquestioningly. Thus most of the conversations recorded here are at cross-purposes to start with.Borradori provides brief introductions for each interview, betraying little familiarity with the work of the philosophers, particularly when the work involved is at all technical, or more than about ten years old. Except to summarize these summaries her general introduction for the volume does no more than to indulge in the kind of military and cartographic metaphors made tiresomely familiar by such recent European thinkers as Foucault. Little seems to have been lost in the retranslation of this volume from the Italian, except that the historian of science George Sarton has somehow become “Georges Sardon” (p. 31).David GormanNorthern Illinois UniversityCopyright © 1995 The Johns Hopkins University Press...

Horgan and Timmons, with their Moral Twin Earth arguments, argue that the new moral realism falls prey to either objectionable relativism or referential indeterminacy. The Moral Twin Earth thought experiment on which the arguments are based relies in crucial ways on the use of intuitions. First, it builds on Putnam’s well-known Twin Earth example and the conclusions drawn from that about the meaning of kind names. Further, it relies on the intuition that were Earthers and (...) class='Hi'>Twin Earthers to meet, they would be able to have genuine moral disagreements. I will argue that the similarities with Putnam’s thought experiment are questionable and so the reliance on Putnam-like intuitions is questionable. I will then further argue that even if we accept the intuitions that Horgan and Timmons rely on, the anti-realist conclusion is not warranted due to there being more to the meaning of kind terms than the argument assumes. Once we develop the meaning of kind terms further we can acknowledge both that Earthers and Twin Earthers refer to different properties with their moral terms, and that in spite of that they can have a substantive disagreement due to a shared meaning component.

"The first two lectures place the alternative I defend -- a kind of pragmatic realism -- in a historical and metaphysical context. Part of that context is provided by Husserl's remark that the history of modern philosophy begins with Galileo -- that is, modern philosophy has been hypnotized by the idea that scientific facts are all the facts there are. Another part is provided by the analysis of a very simple example of what I call 'contextual relativity'. The position (...) I defend holds that truth depends on conceptual scheme and it is nonetheless 'real truth'. "In my third lecture I turn to the Kantian antecedents of this view, explaining what I think should be retained of the Kantian idea of autonomy as the central theme of morality, and extracting from Kant's work a 'moral image of the world' that connects the ideals of equality and intellectual liberty. In this lecture I defend the idea that moral images are an indispensible part of our moral and cultural heritage. "In the final lecture I defend the idea of moral objectivity. I compare our epistemological positions in ethics, history, analysis of human character, and science, and I argue that in no area can we hope for a 'foundation' which is more ultimate than the beliefs that actually, at a given time, function as foundational in the area, the beliefs concerning which one has to say 'this is where my spade is turned'. In ethics such beliefs are represented in moral images of the world.". (shrink)

UNCLEAR as it is, the traditional doctrine that the notion "meaning" possesses the extension/intension ambiguity has certain typical consequences. The doctrine that the meaning of a term is a concept carried the implication that mean- ings are mental entities. Frege, however, rebelled against this "psy- chologism." Feeling that meanings are public property-that the same meaning can be "grasped" by more than one person and by persons at different times-he identified concepts (and hence "intensions" or meanings) with abstract entities rather than (...) mental entities. However, "grasping" these abstract entities was still an individual psychological act. None of these philosophers doubted that understanding a word (knowing its intension) was just a matter of being in a certain psychological state (somewhat in the way in which knowing how to factor numbers in one's head is just a mat- ter of being in a certain very complex psychological state).

In lieu of an abstract, here is a brief excerpt of the content:Evil as the Good?A Reply to Brook ZiporynDavid R. LoyI was surprised to receive this lengthy response to my short review—yet not displeased, for the important question is, of course, how much Professor Ziporyn's reply helps to clarify the issues at stake, which we agree deserve to be pursued. One of the many admirable aspects of his Evil and/or/as the Good is that, in addition to presenting the Tiantai (...) ethical position in its historical context, it argues forcefully for the validity and relevance of that approach today. Moreover, I am pleased at the way Ziporyn's response focuses the argument of his rich and dense book, so I welcome this opportunity to continue the discussion. And perhaps those who have read this far will also be pleased that I am able to present my main concerns somewhat more concisely.Ziporyn begins with the relationship between ultimate and provisional truth, usually the crux of the matter from a Mahāyāna perspective. In response to a point I make—that ethically the nondual 'ultimate' point of view needs to be supplemented by a provisional 'lower truth' that distinguishes between good and evil—he emphasizes that according to Tiantai "conventional truth and ultimate truth are actually identical" (his italics) and that the conventional truth embraces all possible assertions, beliefs, and positions. Later, he elaborates that "provisional truth is a portion of ultimate truth, in a peculiar omnicentric sort of whole/part relation in which each part in fact contains the whole." The important term remains identity, for according to Tiantai "the idea that two entities might be mutually implicative and dependent, not adventitiously but in their nature, and yet not identical, is logically impossible." Ethically, of course, this means something more than the interdependence of good and evil: it is not only that "the most horrible evils are ineradicable, built into the absolute unchangeable nature of all existence, and fully and eternally present even in Buddhahood," but that "greed, anger, and delusion would be seen to be identical with Buddhahood, in accordance with precisely this Tiantai doctrine of the interpenetration of good and evil."As in the original review, my main point is that this emphasis on the identity of conventional truth and ultimate truth is an important insight, but one that turns out to be quite problematic ethically. Its value is mostly epistemological and metaphysical: it helps us escape from the kind of dualism that often postulates some 'higher' transcendental reality corresponding to a 'higher' ultimate truth. Instead, the 'higher' is not separate from the provisional and conventional, but the truth (whether realized or not) is that the whole 'ultimate' is completely contained within each conventional part or provisional position.Dōgen somewhere makes the point that the goal is not to eradicate concepts (which is a dualistic approach to practice, seeking a purified mind that transcends language) but to liberate concepts. What becomes important is our ability to move [End Page 348] (and play) freely among the multiplicity of linguistic possibilities—in Ziporyn's terms, to 'recontextualize' without getting stuck in any particular context or conceptual system. Nothing is lacking in any of these possibilities; in terms of Indra's Net, each node manifests the whole. We are not liberated from language, except in the sense that we are not trapped in any particular language game; rather, we are liberated in language. We should not blame the victim: the problem is not language itself, but our tendencies to cling to some concepts, et cetera, more than others- including, for example, our dualistic tendency to discriminate between 'good' and 'evil' in order to identify with the former by annihilating the latter (a very timely topic, unfortunately).But good and evil for Ziporyn are more than interdependent. He claims that they are identical, and that is where difficulties arise. The epistemological point about the identity of the two truths becomes more problematical when we move into ethics, where the 'cash value' is somewhat more obvious and immediate, in the sense that we need ethics to help us cope with moral choices that we find ourselves required to make in daily life, in circumstances not always...

In Reason, Truth, and History Hilary Putnam has presented an anti-skeptical argument purporting to prove that we are not brains in a vat. How exactly the argument goes is somewhat controversial. A number of competing "recon¬structions" have been proposed. They suffer from a defect which they share with what seems to be Putnam's own version of the argument. In this paper, I examine a very simple and rather natural reconstruction of the argument, one that does not employ (...) any premises in which a sentence, viz. the sentence 'I am a brain in a vat', is mentioned rather than used. In this respect my version of the argument is importantly different from what appears to be Putnam's own version. (shrink)

The philosophical interest of verbal disputes is twofold. First, they play a key role in philosophical method. Many philosophical disagreements are at least partly verbal, and almost every philosophical dispute has been diagnosed as verbal at some point. Here we can see the diagnosis of verbal disputes as a tool for philosophical progress. Second, they are interesting as a subject matter for first-order philosophy. Reflection on the existence and nature of verbal disputes can reveal something about the nature of concepts, (...) language, and meaning. In this article I first characterize verbal disputes, spell out a method for isolating and resolving them, and draw out conclusions for philosophical methodology. I then use the framework to draw out consequences in first-order philosophy. In particular, I argue that the analysis of verbal disputes can be used to support the existence of a distinctive sort of primitive concept and that it can be used to reconstruct a version of an analytic/synthetic distinction, where both are characterized in dialectical terms alone.

This lecture, given at Beijing University in 1984, presents a remarkable (previously unpublished) proof of the Gödel Incompleteness Theorem due to Kripke. Today we know purely algebraic techniques that can be used to give direct proofs of the existence of nonstandard models in a style with which ordinary mathematicians feel perfectly comfortable--techniques that do not even require knowledge of the Completeness Theorem or even require that logic itself be axiomatized. Kripke used these techniques to establish incompleteness by means that could, (...) in principle, have been understood by nineteenth-century mathematicians. The proof exhibits a statement of number theory--one which is not at all "self referring"--and constructs two models, in one of which it is true and in the other of which it is false, thereby establishing "undecidability" (independence).

Propositions are the referents of the ‘that’-clauses that appear in the direct object positions of typical ascriptions of assertion, belief, and other binary cognitive relations. In that sense, propositions are the objects of those cognitive relations. Propositions are also the semantic contents (meanings, in one sense ) of declarative sentences, with respect to contexts. They are what sentences semantically express, with respect to contexts. Propositions also bear truth-values. The truth-value of a sentence, in a context, is the truth-value of (...) the proposition that it semantically expresses, in that context. This much is common ground among many (but not all) philosophers. I accept other claims about propositions that are more controversial. Propositions (I hold) are Russellian: they are structured entities whose constituents include individuals, properties, and relations. The contribution of a proper name to the proposition that a sentence semantically expresses (in a context) is the referent of that name. Thus, the semantic content of ‘Bill Clinton’ is Bill Clinton himself, and the semantic content of ‘Bill Clinton smokes’ is a proposition whose constituents are Bill Clinton and the property of smoking (ignoring tense, as I shall do from here on). Such 1 singular propositions are among the objects of belief, assertion, and other cognitive relations. This combination of a Millian view about proper names with a Russellian theory of propositions might appropriately be called ‘Millian Russellianism’, or ‘MR’ for short. David Chalmers, in his stimulating paper “Probability and Propositions,” defines a closely related view, Referentialism, as follows (see also the penultimate paragraph of his introduction). Referentialist views say that insofar as beliefs are about individuals (such as Nietzche), the objects of these belief are determined by those individuals. On one such view, the objects of belief are Russellian propositions composed from the individuals and properties that one’s belief is about.. (shrink)

This is the third volume of Hilary Putnam's philosophical papers, published in paperback for the first time. The volume contains his major essays from 1975 to 1982, which reveal a large shift in emphasis in the 'realist'_position developed in his earlier work. While not renouncing those views, Professor Putnam has continued to explore their epistemological consequences and conceptual history. He now, crucially, sees theories of truth and of meaning that derive from a firm notion of reference as inadequate.
