Christopher Norris

This book was written with a view to sorting our some of the muddles and misreadings - especially misreadings of Kant - that have charaterized recent postmodernist and post-structuralist thought. For these issues have a relevance, as Norris argues, far beyond the academic enclaves of philosophy, literary theory, and cultural criticism. Thus he makes large claims for the importance of getting Kant right on the relation between epistemology, ethics and aesthetics; for pursuing the Kantian question 'What is Enlightenment?' as raised in Foucault's late essays; or again, for recalling William Empson's spirited attempt to reassert the values of reason and truth against the orthodox 'lit crit' wisdom of his time. These are specialized concerns. But for better or worse it has been largely in the context of 'theory'- that capacious though ill-defined genre- that such issues have received their most scrutiny over the past two decades. As its title suggests, The Truth About Postmodernism disputes a good deal of what currently passes for advance theoretical wisdom. Above all it mounts a challenge to those fashionable doctrines - variants of the 'end-of-ideology' theme - that assimilate truth to some existing range of language-games, discourses, or in-place consensus beliefs. Norris's book will be welcomed for its clarity of style, its depth of philosophical engagement, and its refusal to endorse the more facile varieties of present-day textualist thought. It will also serve as a timely reminder that the 'politics of theory' cannot be practised in safe isolation from the politics of activist social concern

In this essay I examine various aspects of the nearcentury-long debate concerning the conceptualfoundations of quantum mechanics and the problems ithas posed for physicists and philosophers fromEinstein to the present. Most crucial here is theissue of realism and the question whether quantumtheory is compatible with any kind of realist orcausal-explanatory account which goes beyond theempirical-predictive data. This was Einstein's chiefconcern in the famous series of exchanges with NielsBohr when he refused to accept the truth orcompleteness of a doctrine (orthodox QM) which ruledsuch questions to be strictly inadmissible. I discussthe later history of quantum-theoretical debate withparticular reference to the issue of nonlocality,i.e., the phenomenon of superluminal(faster-than-light) interaction betweenwidely-separated particles. Then I show how thestandard `Copenhagen' interpretation of QM hasinfluenced current anti-realist orontological-relativist approaches to philosophy ofscience. Indeed, there are clear signs that somephilosophers have retreated from a realist positionvery largely in response to just these problems. So itis important to ask exactly why – on what scientificor philosophical grounds – any preferred alternative(causal-realist) construal should have been ruled outas a matter of orthodox QM wisdom. Moreconstructively, my paper presents various arguments infavour of one such alternative, the `hidden-variables'theory developed since the early 1950s by David Bohmand consistently marginalised by proponents of theCopenhagen doctrine.

This article offers a critical perspective on two lines of thought in recent epistemology and philosophy of science, namely Michael Dummett?s anti-realist approach to issues of truth, meaning, and knowledge and Bas van Fraassen?s influential programme of?constructive empiricism?. While not denying the salient differences between them it shows how they converge on a sceptical outlook concerning the realist claim that truth might always transcend the restrictions of some given state of knowledge. The author puts the case that such sceptical arguments, if followed through consistently, must involve giving up all claim to account for our knowledge of the growth of scientific knowledge. He also takes issue with Dummett?s idea of truth as nothing more than a matter of?warranted assertibility? and with van Fraassen?s likewise verificationist conception of empirical warrant as the most we can have by way of epistemic justification. Thus it is wrong to suppose that the realist is merely indulging in a display of? courage not under fire? when she assumes ontological commitments in excess of the observational data. This disavowal of realism in favour of a theory which?saves the appearances? has a less-than-distinguished prehistory in the range of compromise strategies adopted by upholders of a dominant metaphysics or world-view, starting out with the orthodox Catholic attempt to defuse the implications of the heliocentric hypothesis advanced by Copernicus and Galileo. Such theological motives are nowadays not so prominent although? it is suggested fithey do emerge at certain points in Dummett?s writing. More constructively, this article presents a case for objectivism with regard to scientific truth and also for inference to the best causal explanation on both the micro- and the macrophysical scale as the only approach with an adequate claim to make sense of the history of advancements in scientific knowledge to date

In this interview, Christopher Norris discusses a wide range of issues having to do with postmodernism, deconstruction and other controversial topics of debate within present-day philosophy and critical theory. More specifically he challenges the view of deconstruction as just another offshoot of the broader postmodernist trend in cultural studies and the social sciences. Norris puts the case for deconstruction as continuing the 'unfinished project of modernity' and—in particular—for Derrida's work as sustaining the values of enlightened critical reason in various spheres of thought from epistemology to ethics, sociology and politics. Along the way he addresses a number of questions that have lately been raised with particular urgency for teachers and educationalists, among them the revival of creationist doctrine and the idea of scientific knowledge as a social, cultural, or discursive construct. In this context he addresses the 'science wars' or the debate between those who uphold t

This paper argues the case for ontological realism as against various present‐day forms of conventionalist, instrumentalist, cultural‐relativist, or anti‐realist doctrine. In particular it takes issue with Richard Rorty’s writings on philosophy of science – where these ideas receive their most extreme and provocative statement – and with Bas van Fraassen’s more moderate ‘constructive empiricist’ approach. This latter entails ontological commitment to whatever shows up through trained observation or empirical research. However, it refuses to countenance realist claims concerning the existence of (as yet) unobserved entities and their role in explanatory theories premised on putative laws of nature. I maintain that van Fraassen’s position is: (1) inadequate to account for our knowledge of the growth of scientific knowledge; (2) self‐refuting since often undermined by examples which he himself supplies; and (3) incapable of mounting resistance to other, more wholesale (e.g., Rortian) varieties of anti‐realist argument. Only by combining causal realism with a principle of inference to the best explanation can philosophy of science avoid these kinds of hyperinduced sceptical doubt.

In this essay, I offer a critical evaluation of Hilary Putnam's writings on epistemology and philosophy of science, in particular his engagement with interpretative problems in quantum mechanics. I trace the development of his thinking from the late 1960s when he adopted a strong causal-realist position on issues of meaning, reference, and truth, via the "internal realist" approach of his middle-period writings, to the various forms of pragmatist, naturalized, or "commonsense" epistemology proposed in his latest books. My contention is that Putnam's retreat from a full-fledged realist outlook has been prompted in large part by his belief that it cannot possibly be reconciled with the implications of quantum mechanics for our understanding of processes and events in the subatomic domain. However, I suggest, this response should be seen as premature given the range of as-yet unresolved problems with quantum mechanics on the orthodox (Copenhagen) interpretation and also the existence of an alternative account - David Bohm's hidden-variables theory - which perfectly matches the established predictive-observational results while providing a credible realist ontology. I also examine Putnam's case for adopting a nonstandard (three-valued) "quantum logic" in relation to the thinking of other philosophers - Michael Dummett among them - who have espoused a more global or doctrinaire version of anti-realism. I conclude that Putnam's early (causal-realist) position is by no means untenable in light of the various arguments that he now takes as counting decisively against it.

This book is a critical introduction to the long-standing debate concerning the conceptual foundations of quantum mechanics and the problems it has posed for physicists and philosophers from Einstein to the present. Quantum theory has been a major infulence on postmodernism, and presents significant problems for realists. Keeping his own realist position in check, Christopher Norris subjects a wide range of key opponents and supporters of realism to a high and equal level of scrutiny. With a characteristic combination of rigour and intellectual generosity, he draws out the merits and weaknesses from opposing arguments. In a sequence of closely argued chapters, Norris examines the premises of orthodox quantum theory, as developed most influentially by Bohr and Heisenberg, and its impact on varous philosophical developments. These include the ideas developed by W.V Quine, Thomas Kuhn, Michael Dummett, Bas van Fraassen, and Hilary Puttnam. In each case, Norris argues, these thinkers have been influenced by the orthodox construal of quantum mechanics as requiring drastic revision of principles which had hitherto defined the very nature of scientific method, causal explanati and rational enquiry. Putting the case for a realist approach which adheres to well-tried scientific principles of causal reasoning and inference to the best explanation, Christopher Norris clarifies these debates to a non-specialist readership and scholars of philosophy, science studies and the philosophy of science alike. Quantum Theory and the Flight From Realism suggests that philosophical reflection can contribute to a better understanding of these crucial, current issues.

This article offers a critical review of various ontological-relativist arguments, mostly deriving from the work of W. V. Quine and Thomas K hn. I maintain that these arguments are (1) internally contradictory, (2) incapable of accounting for our knowledge of the growth of scientific knowledge, and (3) shown up as fallacious from the standpoint of a causal-realist approach to issues of truth, meaning, and interpretation. Moreover, they have often been viewed as lending support to such programmes as the 'strong' sociology of knowledge and the turn towards wholesale cultural-relativist doctrines, whether of the Wittgensteinian ('language-games') or Heideggerian (depth-hermeneutic) varieties. Thus Richard Rorty recommends that we should henceforth drop all that old-fashioned talk of 'truth', 'knowledge', or 'reality', since whatever warrants those descriptions from time to time is just the product of some currently favoured language-game or range of elective metaphors. Such ideas have little in common with Quine's general outlook of robust physicalism, nor again - though the case is less clear - with Kuhn's reconsidered approach to these issues as set forth in his 1969 Postscript to The Structure of Scientific Revolutions . However, both thinkers have left themselves open to misconstrual by adopting a sceptical-relativist fallback position in response to the well-known problems with logical empiricism. This essay therefore reviews those problems with reference to alternative, more adequate accounts of what is involved in the process of scientific discovery and theory-change.

Truth, Christopher Norris reminds us, is very much out of fashion at the moment whether at the hands of politicians, media pundits, or purveyors of postmodern wisdom in cultural and literary studies. Across a range of disciplines the idea has taken hold that truth-talk is either redundant or the product of epistemic might. Questions of truth and falsehood are always internal to some specific language-game; history is just another kind of fiction; philosophy is only a kind of writing; law is a wholly rhetorical practice. In _Reclaiming Truth_, Norris critiques these fashionable trends of thought and mounts a specific challenge to cultural relativist doctrines in epistemology, philosophy of science, ethics, and political theory. Norris presents his case in a series of closely argued chapters that take issue with the relativist position. He attempts to rehabilitate the value of truth in philosophy of science by restoring a lost distinction between concept and metaphor and argues that theoretical discourse, so far from being an inconsequential activity, has very real consequences, particularly in ethics and politics. This debate has become skewed, he suggests, through the widespread and typically postmodern idea that truth-claims must always go along with a presumptive or authoritarian bid to silence opposing views. On the contrary, there is nothing as dogmatic—or as silencing—as a relativism that acknowledges no shared truth conditions for valid or responsible discourse. Norris also offers a timely reassessment of several thinkers—Althusser and Derrida among them—whose reception history has been distorted by the vagaries of short-term intellectual fashion. _Reclaiming Truth _will be welcomed by readers concerned with the uses and abuses of theory at a time when such questions are in urgent need of sustained and serious debate.

This essay responds to Jeff Malpas's foregoing article, itself written in response to my various publications over the past two decades concerning Donald Davidson's ideas about truth, meaning, and interpretation. It has to do mainly with our disagreement as regards the substantive content of Davidson's truth-based semantic approach in relation to the problematic legacy of logical empiricism, including Quine's incisive but no less problematical critique of that legacy. I also raise questions with respect to Malpas's coupling of Davidson with Heidegger, intended to provide a more adequate depth-ontological grounding for the formalized (logico-semantic) conception of truth that Davidson adopts from Tarski. My essay then argues the case for an outlook of objectivist causal realism joined with a theory of inference to the best, most rational explanation that would satisfy this need in more philosophically (as well as scientifically) accountable terms.

Alain Badiou is a highly original, indeed decidedly iconoclastic thinker whose work has ranged widely over areas of equal concern to philosophers in the ‘continental’ and mainstream analytic traditions. These areas include ontology, epistemology, ethics, politics, and – above all – philosophy of mathematics. It is unfortunate, and symptomatic of prevailing attitudes, that his work has so far receivedminimal attention from commentators in the analytic line of descent. Here I try to help the process of reception along by describing Badiou’s remarkably ambitious approach to issues of mathematical (more specifically: of set-theoretical) ontology, and by explaining just where his project stands in relation to some major issues within current analytic debate. Chief among them are: the issue between realists and anti-realists – along with various avowed middle-ground or compromise solutions – and those oddly tenacious problems-from-Wittgenstein (e.g., concerning what it means to follow a rule) that have so preoccupied philosophers over the past decade. In particular I stress the unusual, indeed unique combination in his thought of high formal rigour and conceptual clarity allied to a speculative scope and inventiveness which tend to make those other discussions appear somewhat self-absorbed and parochial. Most importantly, Badiou engages these issues at a level of creative as well as of technical or analytic grasp, which puts his thinking closely in touch with the way that set theory has itself evolved through a constant process of – in Badiou’s phrase – ‘turning paradoxes into concepts.’ I also discuss his strong and principled rejection of the ‘linguistic turn’ in its manifold (analytic and continental) variants, and his idea of the ‘event’ as that which inherently eludes or surpasses the conceptual resources of any received ontology, whether in mathematics and the natural sciences or in the history of genuinely epochal changes in politics and ethics. All in all, I put the case for Badiou as a thinker of the first importance not only for the impressive range, depth and originality of his work, but also because it points to an escape-route from some of the more cramped or windowless quarters of present-day philosophic thought

In this book Christopher Norris develops the case for scientific realism by tackling various adversary arguments from a range of anti-realist positions. Through a close critical reading he shows how they fail to make adequate sense on any rational, consistent and scientifically informed survey of the evidence. Along the way he incorporates a number of detailed case-studies from the history and philosophy of science. Norris devotes much of his discussion to some of the most prominent and widely influential source-texts of anti-realism. Also included are the sophisticated versions of verificationism developed by thinkers such as Michael Dummett and Bas van Fraassen. Central to Norris's argument is a prolonged engagement with the once highly influential but nowadays neglected work of Norwood Russell Hanson. This book will be welcomed especially by readers who possess some knowledge of the background debate and who wish to deepen and extend their understanding of these issues beyond an introductory level.

This article examines Hilary Putnam's work in the philosophy of mathematics and - more specifically - his arguments against mathematical realism or objectivism. These include a wide range of considerations, from Gödel's incompleteness-theorem and the limits of axiomatic set-theory as formalised in the Löwenheim-Skolem proof to Wittgenstein's sceptical thoughts about rule-following, Michael Dummett's anti-realist philosophy of mathematics, and certain problems – as Putnam sees them – with the conceptual foundations of Peano arithmetic. He also adopts a thought-experimental approach – a variant of Descartes' dream scenario – in order to establish the in-principle possibility that we might be deceived by the apparent self-evidence of basic arithmetical truths or that it might be ‘rational’ to doubt them under some conceivable set of circumstances. Thus Putnam assumes that mathematical realism involves a self-contradictory ‘Platonist’ idea of our somehow having quasi-perceptual epistemic ‘contact’ with truths that in their very nature transcend the utmost reach of human cognitive grasp. On this account, quite simply, ‘nothing works’ in philosophy of mathematics since wecan either cling to that unworkable notion of objective truth or abandon mathematical realism in favour of a verificationist approach that restricts the range of admissible statements to those for which we happen to possess some means of proof or ascertainment. My essay puts the case, conversely, that these hyperbolic doubts are not forced upon us but result from a false understanding of mathematical realism – a curious mixture of idealist and empiricist themes – which effectively skews the debate toward a preordained sceptical conclusion. I then go on to mount a defence of mathematical realism with reference to recent work in this field and also to indicate some problems – as I seethem – with Putnam's thought-experimental approach as well ashis use of anti-realist arguments from Dummett, Kripke, Wittgenstein, and others.

This essay argues a case for viewing Derrida's work in the context of recent French epistemology and philosophy of science; more specifically, the critical‐rationalist approach exemplified by thinkers such as Bachelard and Canguilhem. I trace this line of descent principally through Derrida's essay ‘White Mythology: Metaphor in the Text of Philosophy’. My conclusions are (1) that we get Derrida wrong if we read him as a fargone antirealist for whom there is nothing ‘outside the text'; (2) that he provides some powerful counter‐arguments to this and other items of current postmodern wisdom; (3) that deconstruction is more aptly viewed as continuing the epistemo‐critical approach developed by thinkers like Bachelard; and (4) that it also holds important lessons for philosophy of science in the mainstream Anglo‐ American ‘analytic’ tradition.

In this sweeping volume, Christopher Norris challenges the view that there is no room for productive engagement between mainstream analytic philosophers and thinkers in the post-Kantian continental line of descent. On the contrary, he argues, this view is simply the product of a limiting perspective that accompanied the rise of logical positivism. Norris reveals the various shared concerns that have often been obscured by parochial interests or the desire to stake out separate philosophical territory. He examines the problems that emerged within the analytic tradition as a result of its turn against Husserlian phenomenology and its outright rejection of what came to be seen as a merely "psychologistic" approach to issues of meaning, knowledge, and truth. Norris shows how these problems have resurfaced in various forms from the heyday of logical empiricism to the present. He provides critical readings of such philosophers as Willard Quine, Thomas Kuhn, Donald Davidson, Hilary Putnam, Richard Rorty, Michael Dummett, Thomas Nagel, and John McDowell. He also offers a running discussion of Wittgenstein's influence and its harmful effect in promoting a placidly consensus-based theory of knowledge. On the continental side, Norris argues for a reassessment of Husserl's phenomenological project and its potential contribution to present-day Anglo-American debates in epistemology and philosophy of science. He discusses Bachelard, Canguilhem, and the French tradition of rationalisme applique as an alternative to Kuhnian conceptions of scientific paradigm change. This leads him to suggest a non-Wittgensteinian way around the problems that have dogged more traditional theories of knowledge andtruth. In two chapters on the work of Jacques Derrida, Norris explores the "supplementary" logic of deconstruction and compares it with other recent proposals for a nonstandard logic. Here again he stresses the community of interests between the two philosophical cultures and the extent to which continental thinking has engaged certain issues with a rigor largely ignored by Anglophone writers. By bringing a fresh perspective to questions that have often been considered the exclusive preserve of analytic philosophy, Norris offers an overview of current debates that is at once refreshingly open-minded and sure of its own argumentative bearings.

Norris presents a series of closely linked chapters on recent developments in epistemology, philosophy of language, cognitive science, literary theory, musicology and other related fields. While to this extent adopting an interdisciplinary approach, Norris also very forcefully challenges the view that the academic "disciplines" as we know them are so many artificial constructs of recent date and with no further role than to prop up existing divisions of intellectual labour. He makes his case through some exceptionally acute revisionist readings of diverse thinkers such as Derrida, Paul de Man, Wittgenstein, Chomsky, Michael Dummett and John McDowell. In each instance Norris stresses the value of bringing various trans-disciplinary perspectives to bear while none-the-less maintaining adequate standards of area-specific relevance and method. Most importantly he asserts the central role of recent developments in cognitive science as pointing a way beyond certain otherwise intractable problems in philosophy of mind and language.

This essay examines some of the arguments in David Deutsch's book The Fabric of Reality , chief among them its case for the so-called many-universe interpretation of quantum mechanics (QM), presented as the only physically and logically consistent solution to the QM paradoxes of wave/particle dualism, remote simultaneous interaction, the observer-induced 'collapse of the wave-packet', etc. The hypothesis assumes that all possible outcomes are realized in every such momentary 'collapse', since the observer splits off into so many parallel, coexisting, but epistemically non-interaccessible 'worlds' whose subsequent branchings constitute the lifeline-or experiential world-series- for each of those proliferating centres of consciousness. Although Deutsch concedes that his 'multiverse' theory is counter-intuitive, he none the less takes it to be borne out beyond question by the sheer observational/predictive success of QM and the conceptual dilemmas that supposedly arise with alternative (single-universe) accounts. Moreover, he claims the theory resolves a range of longstanding philosophical problems, notably those of mind/body dualism, the various traditional paradoxes of time, and the freewill/determinism issue. The essay suggests on the contrary, that Deutsch unwittingly transposes into the framework of presentday quantum debate speculative themes from the history of rationalist metaphysics, often with bizarre or philosophically dubious results, and that he rules out at least one promising rival account, namely Bohm's 'hidden variables' theory. It goes on to consider reasons for resistance to that theory among proponents of the 'orthodox' (Copenhagen) doctrine, and for the strong anti-realist, at times even irrationalist bias that has characterized much of this discussion since Bohr's debates with Einstein about quantum non-locality, observer-intervention, and the limits of precise measurement. Finally, the contrast is pointed out between Deutsch's ontologically extravagant use of the many-worlds hypothesis (akin to certain ideas advanced by speculative metaphysicians from Leibniz down) and those realist modes of counterfactual reasoning- e.g. in Kripke and the early Putnam- which deploy similar arguments to very different causal-explanatory ends.
