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.

This Routledge Revival , first published in 1985, gives detailed attention to the bearing of literary theory on questions of truth, meaning and reference. On the one hand, deconstruction brings a vigilant awareness of the figural and narrative tropes that make up the discourse of philosophic reason. On the other it insists that argumentative rigour cannot be divorced from the kind of close reading that has come to characterize literary theory in its more advanced or speculative forms. This present-day ‘contest of faculties’ has large implications for philosophers and critics, many of whom will welcome the reissue of such a clear-headed statement of the impact of deconstruction

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.

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.
