[Brian P. McLaughlin] In recent years, some philosophers have claimed that we can know a priori that certain external world skeptical hypotheses are false on the basis of a priori knowledge that we are in certain kinds of mental states, and a priori knowledge that those mental states are individuated by contingent environmental factors. Appealing to a distinction between weak and strong a priority, I argue that weakly a priori arguments of this sort would beg the question of whether the (...) skeptical hypothesis under assessment is true, and that the prospect of a sound strongly a priori argument of this sort seems dim. \\\ [David Owens] Contemporary discussion of scepticism focuses on the possibility that most or all of our beliefs might be false. I argue that the hypothesis of massive falsity and the associated 'problem of the external world' are inessential to the scepticisms of Descartes and Hume. What drives Cartesian and Humean scepticism is the demand for certainty: any possibility of error, however local, must be ruled out before we can claim either justified belief or knowledge. Contemporary philosophers have ignored this form of scepticism because they doubt that the demand for certainty can be motivated. But Descartes provides a sound motivation for this demand in the Meditations. (shrink)

This volume is a collective exploration of major themes in the work of Crispin Wright, one of today's leading philosophers. These newly commissioned papers are divided into four sections, preceded by a substantial Introduction, which places them in the context of the development of Wright's ideas. The distinguished contributors address issues such as the rule-following problem, knowledge of our meanings and minds, truth, realism, anti-realism and relativism, as well as the nature of perceptual justification, the cogency of arguments such as (...) G. E. Moore's celebrated proof of an external world, and skepticism about the material world. Some papers explore the relationship of Wright's ideas with those of Ludwig Wittgenstein, whose influence has always been a prominent aspect of Wright's philosophy. The essays collectively testify to the enormous interest and relevance of Wright's seminal contributions for present-day debates in areas as diverse as the philosophy of language and mind, metaphysics, and epistemology, and significantly advance research in these areas. The volume also contains Wright's substantial responses to his critics, which offer the most up-to-date versions of his ideas and a vigorous defense of his philosophy. (shrink)

: For quite some time now there has been an ongoing debate whether authoritative self-knowledge is compatible with anti-individualism.1 One influential line of argument against compatibilism is due to Paul Boghossian (1998). I argue that Boghossian misconstrues what the anti-individualist really is committed to. This defence of compatibilism is elaborated by showing how the Twin Earth thought experiment is meant to speak in favour of anti-individualism. Partly this will show that Boghossian is wrong in his denial that empirical background knowledge (...) is imported into the Twin Earth experiment. The main points argued are that Boghossian fails to realize, both, (1) that anti-individualism does not involve concept-individuation in terms of reference, and (2) that anti-individualism assumes a core of representational success. In effect, these two points constitute an entirely new way to defend compatibilism, a way that seems to have gone unnoticed in the literature. (shrink)

Aimed at philsophy graduates this book investigates mental content in a systematic way and advances a number of claims about how mental content states are related to the body and the world. Internalism is the thesis that they are; externalism is the theory that they are not.

In Reason, Truth and History Hilary Putnam offered an argument purporting to show that Brain-in-a-Vat skepticism can be refuted on the assumption that central features of the causal theory of reference are correct. Many philosophers have discussed Putnam’s proposal, defending both the pro and con sides of the debate. The debate continues in the current literature with Putnamians such as Tymoczko and Dell’Utri offering ever more intricate defenses of the anti-skeptical position and critics such as David and Brueckner rebutting these (...) defenses.

Paul Boghossian has argued that Externalism is incompatible with privileged self-knowledge because (i) the Externalist can cite no property to be the reference of an empty natural kind concept such as the ether; (ii) without reference there is no content; hence (iii) either we do know on the basis of introspection alone whether an apparent natural kind thought has content or not, in which case we can infer from self-knowledge and a priori knowledge of Externalism alone to the existence in (...) our environment of water, gold etc.; (iv) or we do not know, without empirical investigation, whether an apparent natural kind thought has content. An Externalist not wanting to accept either (iii) or (iv) can deny (i). All empty natural kind concepts refer to the necessarily uninstantiated property of being identical to nothing. Since they have different senses and self-knowledge is only held to extend to the existence and identity of sense, this is compatible with privileged self-knowledge, and Externalism is still true of the concepts.

A venerable view, still very much alive, holds that human action is to be explained at least in part in terms of beliefs and desires. Those who advocate the view expect that the psychological theory which explains human behavior will invoke the concepts of belief and desire in a substantive way. I will call this expectation the belief-desire thesis. Though there would surely be a quibble or a caveat here and there, the thesis would be endorsed by an exceptionally heterogeneous (...) collection of psychologists and philosophers ranging from Freud and Hume, to Thomas Szasz and Richard Brandt. Indeed, a number of philosophers have contended that the thesis, or something like it, is embedded in our ordinary, workaday concept of action. If they are right, and I think they are, then insofar as we use the concept of action we are all committed to the belief-desire thesis. My purpose in this paper is to explore the tension between the belief-desire thesis and a widely held assumption about the nature of explanatory psychological theories, an assumption that serves as a fundamental regulative principle for much of contemporary psychological theorizing. This assumption, which for want of a better term I will call the principle of psychological autonomy, will be the focus of the first of the sections below. In the second section I will elaborate a bit on how the belief-desire thesis is to be interpreted, and try to extract from it a principle that will serve as a premise in the argument to follow. In the third section I will set out an argument to the effect that large numbers of belief-desire explanations of action, indeed perhaps the bulk of such explanations, are incompatible with the principle of autonomy. Finally, in the last section, I will fend off a possible objection to my argument. In the process, I will try to make clear just why the argument works and what price we should have to pay if we were resolved to avoid its consequences. (shrink)

1. It seems plausible to say that a language is a system of expressions the use of which is subject to certain rules. It would seem, thus, that learning to use a language is learning to obey the rules for the use of its expressions. However, taken as it stands, this thesis is subject to an obvious and devastating refutation. After formulating this refutation, I shall turn to the constructive task of attempting to restate the thesis in a way which (...) avoids it. In doing so, I shall draw certain distinctions the theoretical elaboration of which will, I believe, yield new insight into the psychology of language and of what might be called “norm conforming behavior” generally. The present paper contains an initial attempt along these lines. (shrink)

In this paper, I argue that subvenient bases of natural kinds and also of thoughts, must be ocnstrued as involving absences.

In this paper, I argue that content externalism and privileged access are compatible, but that one can, in a sense, have privileged access to the world. The supposedly absurd conclusion should be embraced.

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).

Note first that knowledge of one's own thought-contents would not count as a priori according to the usual criteria for knowledge of this kind. Surely, then, incompatibilists are using this term to refer to some other, stipulatively defined, epistemic property. But could this be, as suggested by McKinsey { 1 99 1: 9), the property of being knowable 'just by thinking' or 'from the armchair'? Certainly not if these were metaphors for knowledge attainable on the basis of reason alone, since (...) self-knowledge would fail to come out a priori in this sense. And exactly the same would happen if the property were that of being knowable by inference, since, according to a common intuition, self-knowledge is noninferential. (shrink)

The attempt to hold both anti-individualism and privileged self-knowledge may have the absurd consequence that someone could know a priori propositions that are knowable only empirically. This would be so if such an attempt entailed that one could know a priori both the contents of one’s own thoughts and the anti-individualistic entailments from those thought-contents to the world. For then one could also come to know a priori the empirical conditions entailed by one’s thoughts. But I argue that there is (...) no construal of a priori knowledge that could be used to raise an incompatibility problem of this sort. First, I suggest that the incompatibilist a priori must be a stipulative one, since in none of the main philosophical traditions does knowledge of the contents of one’s thoughts count as a priori. Then, I show that under various possible construals of a priori, the incompatibilist argument would be invalid: either a fallacy of equivocation or an argument without a plausible closure principle guaranteeing transmission of epistemic status from premises to conclusion. Finally, I maintain that the only possible construal of the property of being knowable a priori that avoids invalidity is one that fails to generate the intended reductio. (shrink)

Dry earth seems to its inhabitants (our intrinsic duplicates) just as earth seems to us, that is, it seems to them as though there are rivers and lakes and a clear, odorless liquid flowing from their faucets. But, in fact, this is an illusion; there is no such liquid anywhere on the planet. I address two objections to externalism concerning the nature of the concept that is expressed by the word 'water' in the mouths of the inhabitants of dry earth. (...) Gabriel Segal presents a dilemma for the externalist concerning the application conditions of the concept, and Paul Boghossian presents a dilemma for the externalist concerning the complexity of the concept. I show that, in both cases, the externalist may occupy the horn of his choice without departing from either the letter or spirit of externalism. (shrink)

Several authors (Boghossian 1998; Segal 2000) allege that 'empty' would-be natural kind terms are a problem for anti-individualistic semantics. In this paper I rebut the charge by providing an anti-individualistic semantics for such terms.

If God had looked into our minds he would not have been able to see there whom we were speaking of.

This paper addresses a problem about epistemic warrant. The problem is posed by philosophical arguments for externalism about the contents of thoughts, and similarly by philosophical arguments for architecturalism about thinking, when these arguments are put together with a thesis of first person authority. In each case, first personal knowledge about our thoughts plus the kind of knowledge that is provided by a philosophical argument seem, together, to open an unacceptably ‘non-empirical’ route to knowledge of empirical facts. Furthermore, this unwelcome (...) prospect of transferring a ‘non-empirical’ warrant from premises about our own mental states and about philosophical theory to a conclusion about external environment or internal architecture seems to depend upon little more than the possibility of knowledge by inference. (The use of the scare-quoted term ‘non-empirical’ is explained a couple of paragraphs further on.). (shrink)

In this paper, I defend McKinsey's argument (Analysis 1991) that Burge's antiindividualist position is incompatible with privileged access, viz. the claim that each subject can know his own thought contents just by reflection and without having undertaken an empirical investigation. I argue that Burge thinks that there are certain necessary conditions for a subject to have thoughts involving certain sorts of concepts; these conditions are appropriately different for thoughts involving natural kind concepts and thoughts involving non-natural kind concepts. I use (...) Burge's commitment to these entailments to show that his antiindividualist position is incompatible with privileged access. (shrink)
