Christopher Norris

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.

_Deconstruction: Theory and Practice_ has been acclaimed as by far the most readable, concise and authoritative guide to this topic. Without oversimplifying or glossing over the challenges, Norris makes deconstruction more accessible to the reader. The volume focuses on the works of Jacques Derrida which caused this seismic shift in critical thought, as well as the work of North American critics Paul de Man, Geoffrey Hartman, J. Hillis Miller and Harold Bloom. In this third, revised edition, Norris builds on his 1991 Afterword with an entirely new Postscript, reflecting upon recent critical debate. The Postscript includes an extensive list of recommended reading, complementing what was already one of the most useful bibliographies available.

Should the truth-value of statements be thought of as epistemically constrained or as determined by objective factors that stand quite apart from our best knowledge, evidence, or powers of conceptual grasp? The anti-realist/realist debate turns ultimately on this disagreement. My article takes its lead from a famous pronouncement by US Defense Secretary Donald Rumsfield to the effect that there are ‘known knowns’, i.e. ‘things that we know we know’; ‘known unknowns’, or ‘things we know we do not know’; and lastly, ‘unknown unknowns’, ‘things we don’t know we don’t know’. Whether Rumsfeld was talking gobbledegook, making some acute logical points, or just pulling the wool with regard to Iraq’s disputed weapons capability is matter for debate. Still, his remarks may be useful for clarifying certain fundamental issues about knowledge and truth, especially in the context of assertions - by anti-realist philosophers such as Michael Dummett - that truth cannot possibly transcend our best powers of proof or ascertainment. On the other hand such scruples may have just the opposite (obfuscating) effect when we are faced with a complex and case-specific question, such as whether or not Iraq truly possessed weapons of mass destruction. My article contends that a wide range of reliably knowledge-conducive procedures, while indeed they fall short of absolute, indubitable truth, nonetheless offer grounds for arriving at a reasoned assessment of the evidence and for not consigning statements of the Dummettian ‘disputed class’ to a limbo of ultimate undecidability.

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

This book is concerned chiefly with issues in epistemology, philosophical semantics and philosophy of science. It defends a causal-realist approach to theories and explanations in the natural sciences and a truth-based propositional semantics for natural language derived from various sources, among them unusually in this context the work of William Empson. It argues against various forms of anti-realist doctrine with regard to both the truth-claims of science and the construal of intentions, meanings and beliefs in the process of linguistic understanding. His book will be welcomed for its vigorous arguments and notable clarity of style. It will be of particular interest to teachers and students in philosophy, critical theory, science studies and the history of ideas.
