This book provides an original perspective on the debate about anti-representationalism and the nature of philosophy. This debate has come to prominence in recent years through the work of people like Richard Rorty, Paul Horwich, Huw Price and Amie Thomasson. It is the first book to explicitly consider this well-known pragmatist kind of anti-representationalism in relation to anti-representationalist views in other areas of philosophy, in particular the philosophy of perception and cognitive science. Taking as its point of departure the neo-pragmatism of Rorty and Price, it critiques the way these (and other) thinkers develop, on this basis, a positive view of philosophy and its remit. By examining the debate about representationalism versus anti-representationalism in perception and cognitive science it provides a different way of understanding the significance of neo-pragmatism, as well as providing an independently interesting perspective on these other debates. A central idea in this perspective involves distinguishing between a world-for-us and a world-in-itself, though in a different way from Kant and many other philosophers. The book extends these reflections to examine questions about realism and the limits of metaphysics for anti-representationalist pragmatism, arguing the view can uphold a common sense kind of realism, as well as the value of distinctively philosophical enquiry in metaphysics.

A perennial issue in contemporary philosophy is the question of how, in Wilfrid Sellars’ terms, categories of the ‘manifest image’ relate to those of the ‘scientific image’. A widespread kind of naturalism assumes that the categories of science have a certain kind of ontological priority and that other categories (meaning, mind, morality and so on) have to be somehow placed or located in the world of science to be fully vindicated. Huw Price has argued in several papers that if one gives up a view of how language functions he calls ‘representationalism’ then this way of understanding placement problems—object naturalism—necessarily lapses. Price argues that in foregoing representationalism and embracing semantic deflationism we should remain naturalists, but subject naturalists, seeking to understand the function our different discourses play in our lives as natural beings: the project of global expressivism. This argument has recently been challenged by several authors who argue that object naturalism can coherently and rationally be pursued within a semantic deflationist framework. I will argue that these objections to Price’s view are all ultimately unconvincing given a wide enough purview of the dialectic. The viability and coherence of global expressivism itself, and whether it is the only possible form of subject naturalism, are briefly addressed in conclusion.

Bertrand Russell famously distinguished between ‘Knowledge by Acquaintance’ and ‘Knowledge by Description’. For much of the latter half of the Twentieth Century, many philosophers viewed the notion of acquaintance with suspicion, associating it with Russellian ideas that they would wish to reject. However in the past decade or two the concept has undergone a striking revival in mainstream ‘analytic’ philosophy – acquaintance is, it seems, respectable again. This is the first collection of new essays devoted to the topic of acquaintance, featuring contributions from many of the world’s leading experts in this area. The volume showcases the great variety of topics in philosophy of mind, epistemology and philosophy of language for which philosophers are currently employing the concept of acquaintance. This book features an extensive introduction by one of the editors, which provides some historical background as well as summarizing the main debates and issues in contemporary philosophy where appeals to acquaintance are currently being made. The remaining thirteen essays are grouped thematically into the following four sections: (1) Phenomenal Consciousness, (2) Perceptual Experience, (3) Reference, (4) Epistemology.

Davidson and Chomsky, though differing on much in the study of language, are united in the view that the traditional notion of a shared language, such as English or Norwegian, has no part to play in a scientific or philosophical understanding of linguistic competence and communication. Davidson accepts Chomsky's ideas about our linguistic ability as underpinned by dedicated and possibly hard-wired aspects of the mind/brain, but does not see this as relevant to a constitutive account of meaning and communication; Chomsky sees Davidson's philosophy of language, like all others based on semantic notions, as doomed to obscurity. Against this background I subject Davidson's argument from malapropisms for the view that there are no such things as languages to critical scrutiny. I conclude that it fails to show that communication does not rest on shared languages, but only that we speak a lot more such languages than we are ordinarily inclined to suppose. This consequence, of interest in its own right, also seems absurd. In the context of a Chomsky-Davidson debate, in which one is sceptical of the traditional concept of a language, this provides a corresponding lift for Chomsky's overall perspective on language and the study thereof.

This paper motivates and defends “Rortian realism,” a position that is Rortian in respect of its underlying philosophical theses but non-Rortian in terms of the lessons it draws from these for cultural politics. The philosophical theses amount to what the paper calls Rorty's “anti-representationalism”, arguing that AR is robust to critique as being anti-realist, relativist, or sceptical, invoking Rorty's historicism/ethnocentrism as part of the defence. The latter, however, creates problems for Rorty in so far as his reformative views on the nature of philosophical and academic activity are meant to be foisted on an academy that ex hypothesi holds views different from these. The paper suggests we can motivate a different conception of the consequences of AR more amenable to the academy: Rortian realism, a view that makes greater concessions to realism and a kind of scientific naturalism than Rorty would like, but that for those very reasons is more likely to allow AR to prevail.

Stephen Laurence and Eric Margolis have recently argued that certain kinds of regress arguments against the language of thought (LOT) hypothesis as an account of how we understand natural languages have been answered incorrectly or inadequately by supporters of LOT ('Regress arguments against the language of thought', Analysis, 57 (1), 60-6, J 97). They argue further that this does not undermine the LOT hypothesis, since the main sources of support for LOT are (or might be) independent of it providing an account of how we understand natural language. In my paper I seek to refute both these claims, and reinstate the putative explanation of natural language understanding as a necessarily central part of the support for LOT. The main argument exploits the fact that Laurence and Margolis give too little weight to the ideas (a) that LOT might be innate (b) that for LOT supporters a semantic theory must apply to in-the-head tokens, not linguistic utterances

Noam Chomsky claims that we know the grammatical principles of our languages in pretty much the same sense that we know ordinary things about the world (e.g. facts), a view about linguistic knowledge that I term ''cognitivism''. In much recent philosophy of linguistics (including that sympathetic to Chomsky's general approach to language), cognitivism has been rejected in favour of an account of grammatical competence as some or other form of mental mechanism, describable at various levels of abstraction (''non-cognitivism''). I argue for cognitivism and against non-cognitivism. First, I show that the distinction between competence and performance in current linguistics is as clearly made as ever it was, in spite of recent interest in linguistic processing modules. Second, I use these facts about the practice of theoretical linguistics to refute various proposals for a non-cognitivist construal of grammatical competence, and to support cognitivism by reflecting on the inapplicability of a multi-level account of linguistic competence. Cognitivism is then defended against several objections centring around the problems of rational integration and conceptualization of grammatical knowledge. Finally, the conception of competence argued for in relation to linguistics is placed in the larger context of cognitive science research and its implications for philosophy of mind.

I argue that intentional psychology does not stand in need of vindication by a lower-level implementation theory from cognitive science, in particular the representational theory of mind (RTM), as most famously Jerry Fodor has argued. The stance of the paper is novel in that I claim this holds even if one, in line with Fodor, views intentional psychology as an empirical theory, and its theoretical posits as as real as those of other sciences. I consider four metaphysical arguments for the idea that intentional psychological states, such as beliefs, must be seen as requiring in-the-head mental representations for us to be able to understand their characteristic causal powers and argue that none of them validly generate their desired conclusions. I go on to argue that RTM, or some computational version thereof, is not motivated by appeal to the nature of cognitive science research either. I conclude that intentional psychology, though an empirical theory, is autonomous from details of lower level mechanism in a way that renders RTM unwarranted.

Theory of Science provides an accessible but systematic survey of perspectives on science and rationality through the arguments and ideas of leading thinkers of the 20th century, including Einstein, Carnap, Popper, Kuhn, Feyerabend, Hempel, Gadamer, Foucault, and Harding. The book also gives a critical introduction to scientific methodology, including the relationship between theory and observation, the problem of induction, hypothetic-deductive method, truth and progress, and explanation in natural and human science. The book covers the theory of science â?? part of the syllabus in Examen Philosophicum at The Norwegian University of Science and Technology (NTNU) â?? for which there has hitherto been no unitary text book in English. Theory of Science is also suited to use in other courses at various levels, as well as being of interest to a wider audience concerned with the philosophical and social problems of science.

"A critical investigation of modern naturalism is vitally needed for a deeper understanding of pragmatism's ability to offer enriching perspectives on contemporary philosophy of science. The kind of non-reductive naturalism so often associated with pragmatism needs to be assessed for its plausibility, as does whether a pragmatist perspective on different human ways of conceiving of the world can mediate between different points of view, especially those of natural science and common sense"-- Publisher summary.

In recent work Huw Price has defended what he calls a global expressivist approach to understanding language and its relation to the physical world. Global expressivism rejects a representationalist picture of the language-world relation and thereby, by intention at least, also a certain metaphysical conception of what are commonly known as placement problems: how entities of the everyday, common sense world like mental states, meanings, moral values, modalities and so on fit into the natural world. Global expressivism upholds a commitment to substantive enquiry into the naturalistic basis of thought about the world, but pursues this in a pragmatist or non-representationalist ’key’, thereby rendering—as it sees things—traditional metaphysical questions otiose. I am in broad sympathy with many of Price’s arguments and ideas. However, I believe the specific sub-variety of non-representationalism he develops actually fails to secure the anti-metaphysical results he seeks. My arguments have their starting point in the Carnap-Quine debate. Given Price’s view of this, which I endorse, I think it can be made clear that Quine’s view, or something very close to it, presents us with a coherent example of a non-representationalist metaphysical placement project. Though one might reasonably doubt the rationality of or motivation for such a view, Price’s own strongly naturalistic assumptions, as these are evinced in his so-called ’subject’ naturalism, make that move dialectically unavailable to him. I end with a brief sketch of an alternative non-representationalist and anti-metaphysical position.

I seek to show that we do not need norms in a genuinely naturalistic epistemology. The argumentation is launched against a common conception of such norms as derived through a process of wide reflective equilibrium, where one aims to bring general normative statements into accord with concrete, possibly expert, intuitions about particular cases, taking simultaneously into account relevant scientific findings -- including facts about human psychological abilities -- and philosophical theories. According to this line, it is possible thus to arrive at genuine, general normative statements concerning how we should reason. I maintain that such statements are superfluous or illegitimate for several interlocking reasons. The central arguments are i) that certain norms simply repeat the content of descriptive statements which in any case would have to be taken account of in scientific reasoning; ii) if norms are merely meant to systematize an intuitive capacity for reasoning and forming beliefs, we can make do with honing that capacity; iii) there is no reason to regard principles in a psychological reasoning module as norms rather than simply prescursors of behaviour; iv) we cannot make sense of experts in relation to epistemic rationality; v) making play with the idea of purely philosophical constraints on theories of norms involves reneging on naturalism.

I focus on Fodor’s model of the relationship between special sciences and basic physics, and on a criticism of this model, that it implies that the causal stability of, e.g., the mental in its production of behaviour is nothing short of a miraculous coincidence. David Papineau and Graham Macdonaldendorse this criticism. But it is far less clear than they assume that Fodor’s picture indeed involves coincidences, which in any case their injection of a teleological supplement cannot explain. Papineau’s and Macdonald’s problem is subtly different from a similar one presented by Adrian Cussins. This is no more effective against Fodor’s picture, but the kind of account of the relation between the physical and the psychological which could constitute a solution to Cussins’ problem is one which, for independent reasons, a physicalist of Fodor’s stripe ought to provide

In this paper, I seek to refute arguments for the idea that folk psychological explanation, i.e., the explanation of actions, beliefs and desires in terms of one another, should be understood as being of a different character than ordinary scientific explanations, a view defended most prominently in analytical philosophy by Donald Davidson and John McDowell. My strategy involves arguing both against the extant arguments for the idea that FP must be construed as giving such explanations, and also against the very notion of such a different kind of explanation. I argue first that the in some sense a priori and conceptual nature of folk psychological principles does not support the idea that these are other than empirical generalisations, by appeal to recent nativist ideas in cognitive science and to Lewis's conception of the meaning of theoretical terms. Second, I argue that there is no coherent sense in which folk psychological explanations can be seen as normative. Thirdly, I examine the putatively holistic character of the mental and conclude that that too fails to provide any cogent reasons for viewing folk psychological explanations as different from other kinds of explanation.

The article presents a critical discussion of Larry Laudan's naturalistic metamethodological theory known as normative naturalism (NN). I examine the strongest extant objection to NN, and, with reference to ideas in Freedman ( Philosophy of Science , 66 (Proceedings), pp. S526-S537, 1999), show how NN survives it. I then go on to outline two problems that really do compromise NN. The first revolves around Laudan's conception of the relationship between scientific values and the history of science. Laudan argues we can make sense of progress in science without seeing great scientists in the past as having held the cognitive values and methodological rules we hold today as important for science. I argue this is extremely implausible, and moreover that Laudan must see our values today as justified by reference to the values of past scientists if he is to avoid a pernicious form of relativism. The second problem with NN is that its conception of methodological rules--as hypothetical imperatives linking cognitive means to ends--is untenable. Such rules would not be needed in a scientific community; moreover it is doubtful whether they should class as rules at all. I conclude by suggesting that the distinction between cognitive means and ends which undergirds Laudan's view is intuitively not well founded, and in any case does not provide sufficient materials for a viable normative naturalized epistemology.

Jonathan Knowles argues against theories that seek to provide specific norms for the formation of belief on the basis of empirical sources: the project of naturalized epistemology. He argues that such norms are either not genuinely normative for belief, or are not required for optimal belief formation. An exhaustive classification of such theories is motivated and each variety is discussed in turn. He distinguishes naturalized epistemology from the less committal idea of naturalism, which provides a sense in which we can achieve epistemic normativity without norms.
