Much contemporary thinking about language is animated by the idea that the core function of language is to represent how the world is and that therefore the notion of representation should play a fundamental explanatory role in any explanation of language and language use. The chapters in this volume explore various ways this idea may be challenged as well as obstacles to developing various forms of anti- representationalism. Particular attention is given to deflationary accounts of truth, the role of language in expressing mental states, and the normative and the natural as they relate to issues of representation. The chapters further various fundamental debates in metaphysics—for example, concerning the question of finding a place for moral properties in a naturalistic world view—and illuminate the relation of the recent neo- pragmatist revival to the expressivist stream in analytic philosophy of language.

Pragmatists have traditionally been enemies of representationalism but friends of naturalism, when naturalism is understood to pertain to human subjects, in the sense of Hume and Nietzsche. In this volume Huw Price presents his distinctive version of this traditional combination, as delivered in his René Descartes Lectures at Tilburg University in 2008. Price contrasts his view with other contemporary forms of philosophical naturalism, comparing it with other pragmatist and neo-pragmatist views such as those of Robert Brandom and Simon Blackburn. Linking their different 'expressivist' programmes, Price argues for a radical global expressivism that combines key elements from both. With Paul Horwich and Michael Williams, Brandom and Blackburn respond to Price in new essays. Price replies in the closing essay, emphasising links between his views and those of Wilfrid Sellars. The volume will be of great interest to advanced students of philosophy of language and metaphysics.

Inspired by the work of Wilfrid Sellars, Michael Williams launches an all-out attack on what he calls "phenomenalism," the idea that our knowledge of the world rests on a perceptual or experiential foundation. The point of this wider-than-normal usage of the term "phenomenalism," according to which even some forms of direct realism deserve to be called phenomenalistic, is to call attention to important continuities of thought between theories often thought to be competitors. Williams's target is not phenomenalism in its classical sense-datum and reductionist form but empiricism generally. Williams examines and rejects the idea that, unless our beliefs are answerable to a "given" element in experience, objective knowledge will be impossible. Groundless Belief was first published in 1977. This second edition contains a new afterword in which Williams places his arguments in the context of some current discussions of coherentism versus the Myth of the Given and explains their relation to subsequent developments in his own epistemological views.

Professor Vogel claims that my responses to scepticism leave the traditional problems standing. I argue in reply that he fails to take sufficiently seriously the diagnostic character of my enterprise. My aim is not to offer direct refutations of sceptical arguments, taking such arguments at face value, but to undermine their plausibility by revealing their dependence on unacknowledged and contentious theoretical presuppositions. Professor Rorty is much more sympathetic to my approach but thinks that there is a simpler and more direct way to get the job done: that sketched by Davidson, who argues that scepticism fails because belief is intrinsically veridical. I doubt this. My approach is to identify the distinctively epistemological presuppositions of sceptical argumentation. If this remains undone, Davidsonian reflections on belief and meaning will seem only to transform sceptical problems about knowledge of the world into problems about knowledge of meaning.

IThere are various ways of being a sceptic. Most obviously, perhaps, versions of scepticism can differ with respect to scope. Scepticism can be universal; it can be directed against beliefs belonging to certain broad kinds, say beliefs having to do with the external world; or it can be quite focussed, as in the case of religious scepticism. But there is also the question of force. Some philosophers treat scepticism as a purely theoretical affair, defining it as the thesis that knowledge is impossible. This kind of scepticism, theoretical scepticism, has no essential connection with any particular sceptical practice. A theoretical sceptic does not necessarily entertain doubts or suspend judgment about any particular matter of fact or theory. He may think that the problem of induction is insoluble yet not be seriously concerned that the sun will not rise tomorrow. But in other versions, the force of scepticism is taken to be practical, in which case to be a sceptic is to entertain doubts or suspend judgment, and not just to take a certain theoretical position in epistemology.

Robert Fogelin agrees that arguments for Cartesian sceptism carry a heavy burden of theoretical commitment, for they take for granted, explicitly or implicitly, the foundationalist's idea that experimental knowledge is in some fully general way 'epistemologically prior' to knowledge of the world. He thinks, however, that there is a much more direct and commonsensical route to scepticism. Ordinary knowledge-claims are accepted on the basis of justificatory procedures that fall far short of eliminating all conceivable error-possibilities. As a result, it is always possible, by bringing new errorpossibilities into play, to raise the 'level of scrutiny' to which a given knowledge-claim is subject, so that it no longer seems adequately justified. Philosophical theories of justification can be seen as attempts to repair this fragility of ordinary knowledge. But they fail, all succumbing to the Pyrrhonian modes of assumption, circularity or infinite regress. I argue that Fogelin's conception of varying levels of scrutiny leads at most to fallibilism and not to radical scepticism. More importantly, I show that changing the range of relevant defeaters to a given knowledge claim can do more that impose stricter standards for justification: it can change the subject by altering the direction of inquiry. We see from this that the introduction of 'sceptical hypotheses' (such as that Descartes's Evil Deceiver) are not best seen as raising standards to some maximal level but as introducing a new kind of evaluation which, without commitment to what I call 'epistemological realism,' does nothing to impugn the justificational status of ordinary knowledge-claims entered in ordinary contexts.

[Michael Williams] A response to Sosa's criticisms of Sellars's account of the relation between knowledge and experience, noting that Sellars excludes merely animal knowledge, and hopes to bypass epistemology by an adequate philosophy of mind and language. /// [Ernest Sosa] I give an exposition and critical discussion of Sellars's Myth of the Given, and especially of its epistemic side. In later writings Sellars takes a pragmatist turn in his epistemology. This is explored and compared with his earlier critique of givenist mythology. In response to Michael Williams, it is argued that these issues are importantly independent of philosophy of language or mind, and that my own take on them does not commit me to any absurd radical foundationalism on language or mind. My own take is in line with Descartes' two-level epistemology of cognitio and scientia, a bifurcation that protects him from vicious circularity, and is adaptable for an epistemology naturalized, whether in the way of Quine, or Moore, or Davidson.

PYRRHONIAN SCEPTICISM, as presented in the writings of Sextus Empiricus, differs in various ways from the forms of scepticism that continue to be of such central concern to modern philosophers. Two differences stand out immediately. One is Pyrrhonism's practical orientation. For Sextus, scepticism is a way of life in which suspension of judgment leads to the peace of mind the sceptic identifies with happiness. The other is the puzzling failure on the part of the Pyrrhonists, along with all other ancient sceptics, to formulate the sceptical problem that many modern and contemporary philosophers regard as fundamental and paradigmatic: the problem of our knowledge of the external world.

Genia Schönbaumsfeld argues that Cartesian skepticism is an illusion induced by the “Cartesian Picture” of perceptual knowledge, in which knowledge of the “external world” depends on an inference from how things subjectively seem to one to how they actually are. To show its incoherence, she draws on the work of John McDowell, which she sees as elaborating a central theme from Wittgenstein’s On Certainty. I argue that Cartesian skepticism is not an illusion, as Schönbaumsfeld understands ‘illusion’, and that McDowell’s account of perceptual knowledge is both untenable and incompatible with Wittgenstein’s ideas about knowledge. Schönbaumsfeld thinks that, to understand how perception can engender knowledge of the world, we need a non-Cartesian account of perceptual reasons. Wittgenstein offers a much more radical break with the Cartesian Picture: an account of knowledge without ‘experience’.
