A wide range of biological processes, in all eukaryotes and in some prokaryotes, are controlled by rhythms with a period close to 24 hours. The circadian oscillator, which is responsible for generating these rhythms, is controlled by light signals that maintain its synchrony with the environmental day/night cycle. Higher plants exhibit many circadian rhythms, including rhythms in the transcription of specific genes. Molecular tools derived from such clock‐controlled genes have led to the identification of several circadian rhythm mutants in the (...) genetic model, Arabidopsis thaliana. The extensive understanding of photoperception in this species will make it a powerful system with which to investigate the light regulation of circadian rhythms. We compare Arabidopsis rhythms to the results from other systems, and discuss these data with respect to the current phototransduction models. (shrink)

Social thinkers in all fields are faced with one unavoidable question: what does it mean to be 'human' in the 21st century? As definitions between what is 'animal' and what is 'human' break down, and as emerging technologies such as artificial intelligence and nano- and bio- technologies develop, accepted notions of humanity are rapidly evolving. Humanity 2.0 is an ambitious and groundbreaking book, offering a sweeping overview of key historical, philosophical and theological moments that have shaped our understandings of humanity. (...) Tackling head on the twin taboos that have always hovered over the scientific study of humanity - race and religion - Steve Fuller argues thar far from disappearing, they are being reinvented. Fuller argues that these new developments will force us to decide which features of our current way of life - not least our bodies - are truly needed to remain human, and concludes with a consideration of these changes for ethical and social values more broadly.

What is the function of concepts pertaining to meaning in socio-linguistic practice? In this study, the authors argue that we can approach a satisfactory answer by displacing the standard picture of meaning talk as a sort of description with a picture that takes seriously the similarity between meaning talk and various types of normative injunction. In their discussion of this approach, they investigate the more general question of the nature of the normative, as well as a range of important topics (...) specific to the philosophy of language.

In this challenging and provocative book, Steve Fuller contends that our continuing faith in science in the face of its actual history is best understood as the secular residue of a religiously inspired belief in divine providence. Our faith in science is the promise of a life as it shall be, as science will make it one day. Just as men once put their faith in God's activity in the world, so we now travel to a land promised by (...) science. In "Science", Fuller suggests that the two destinations might be the same one. Fuller sympathetically explores what it might mean to live scientifically. Can science give a sense of completeness to one's life? Can it account for the entirety of what it is to be human? And what does our continuing belief in scientific progress say about us as a species? In answering these questions, Fuller ranges widely over the history of science and religion - from Aristotle and the atomists to Dawkins and the neo-Darwinists - and takes a close look at what science is, how its purpose has changed over the years, and what role religion and in more recent years atheism have played in its progression. Science, argues Fuller, is now undergoing its own version of secularization. We are ceasing to trust science in its institutional forms, formulated by an anointed class of science priests, and instead we are witnessing the emergence of what Fuller calls Protscience' - all sorts of people, from the New Age movement to anti-evolutionists, claiming scientific authority as their own. Fuller shows that these groups are no more anti-scientific than Protestant sects were atheistic. Fearless and thought-provoking, Science questions some of our most fundamental beliefs about the nature and role of science, and is a distinct and important contribution to debates about evolution, intelligent design, atheism, humanism, the notion of scientific progress, and the public understanding of science.

The theory of knowledge, or epistemology, is often regarded as a dry topic that bears little relation to actual knowledge practices. Knowledge: The Philosophical Quest in History addresses this perception by showing the roots, developments and prospects of modern epistemology from its beginnings in the nineteenth century to the present day. Beginning with an introduction to the central questions and problems in theory of knowledge, Steve Fuller goes on to demonstrate that contemporary epistemology is enriched by its interdisciplinarity, analysing (...) keys areas including: Epistemology as Cognitive Economics Epistemology as Divine Psychology Epistemology as Philosophy of Science Epistemology as Sociology of Science Epistemology and Postmodernism. A wide-ranging and historically-informed assessment of the ways in which man has - and continues to - pursue, question, contest, expand and shape knowledge, this book is essential reading anyone in the Humanities and Social Sciences interested in the history and practical application of epistemology.

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. (shrink)

In this paper we will discuss the issue of environmental advocacy in science education in light of William Hare’s concept of open-mindedness. Although we shall assume that science teaching and learning must go beyond the scientific facts and theories and deal with the implications of science for society, we shall argue that science education should also demand an open-mindedness about environmental concerns such that all proposals for sustainability and the like are weighed against the alternatives using the best scientific knowledge (...) available. Our approach will be to describe two examples of environmental education that recommend insufficiently open-minded forms of teaching and a third example that avoids this shortcoming yet provides a sound basis in environmental education.

This dissertation is concerned with normativity both as an explanatory device in the philosophy of language, logic and epistemology and as a philosophical issue in its own right. Following later Wittgenstein and Sellars, it is argued that language is normative, in the first instance because of the fact that speech acts take place within a structure of social norms and institutions. This fact is then utilized to show that important features of semantic content can be explained in terms of such (...) norms. ;This Sellarsian conception of linguistic usage as the performance of acts within a linguistic game of giving and asking for reasons, leads us to focus on inferential proprieties as central to semantic content. It is, then, natural to look at logical vocabulary, paradigmatically 'entails', as expressing the very normative relations definitive of this content. An idea of Brandom's is developed in providing a formal theory of the inferential content of logical vocabulary. Such normative-inferentialist semantic analyses are developed for a wide range of logical systems. ;A certain conception of justification also falls naturally out of this general theory of language. If asserting is an act performed within a linguistic game, then justification can be thought of as a matter of winning such a game, a successfully defending one's assertion in the face of licensed challenges to it. This account is developed, drawing consequences for the theory of rationality and knowledge. ;The second major issue of the dissertation is the theory of the normative itself and much of the constructive work in the philosophy of language, philosophy of logic and epistemology forms a case study for a particular theory of the normative. On the basis of Wittgensteinian considerations, it is argued that normativity must be understood as resting ultimately on social practice. ;We solve problems of earlier accounts of norms by introducing a novel normative relation between assertions of normative propriety and social practices. Normative assertions do not describe existing social standards, but do nonetheless derive their semantic content from those standards. This argument carried through in detail for cases of logical and epistemic vocabulary in the dissertation. (shrink)

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.

The understanding of decision-making systems has come together in recent years to form a unified theory of decision-making in the mammalian brain as arising from multiple, interacting systems (a planning system, a habit system, and a situation-recognition system). This unified decision-making system has multiple potential access points through which it can be driven to make maladaptive choices, particularly choices that entail seeking of certain drugs or behaviors. We identify 10 key vulnerabilities in the system: (1) moving away from homeostasis, (2) (...) changing allostatic set points, (3) euphorigenic signals, (4) overvaluation in the planning system, (5) incorrect search of situation-action-outcome relationships, (6) misclassification of situations, (7) overvaluation in the habit system, (8) a mismatch in the balance of the two decision systems, (9) over-fast discounting processes, and (10) changed learning rates. These vulnerabilities provide a taxonomy of potential problems with decision-making systems. Although each vulnerability can drive an agent to return to the addictive choice, each vulnerability also implies a characteristic symptomology. Different drugs, different behaviors, and different individuals are likely to access different vulnerabilities. This has implications for an individual's susceptibility to addiction and the transition to addiction, for the potential for relapse, and for the potential for treatment. (shrink)

In this detailed study, Christopher Norris defends the kinds of arguments advanced by the early realist, Hilary Putnam. Norris makes a point of placing Putnam's work in a wider philosophical context, and relating it to various current debates in epistemology and philosophy of science. Much like Putnam, Norris is willing to take full account of opposed viewpoints while maintaining a vigorously argued commitment to the values of debate and enquiry.

You will not always agree with Fuller, but he will force you to rethink some of your pet conceptions about how science works." —Isis This is the book that launched the research program of social epistemology, which has fueled imaginations and provoked debates across many disciplines around the world. Its opening question remains as pressing as ever: How should knowledge production be organized? (...) The second edition contains a substantial new introduction, in which Steve Fuller reflects on social epistemology’s place in the history of analytic and continental epistemology and discusses the inspiration he has drawn from a wide variety of fields in the humanities and social sciences. It also includes a spirited attack on alternative philosophical groundings for social epistemology and a detailed response to the standard criticism that social epistemology has received from realist philosophers and natural scientists during the "Science Wars." In its new edition, the book remains a provocative contribution to the debate on the production, dissemination, and interpretation of knowledge in the sciences. (shrink)

Christopher Norris DERRIDA AT YALE: THE "DECONSTRUCTIVE MOMENT" IN MODERNIST POETICS IN seven types of ambiguity, William Empson breezily remarked of his critical method that it was "either all nonsense or all very startling and new." The reactions went very much as Empson predicted, with a whole new school of criticism eagerly latching on to the idea of multiple meanings in poetry, while the sober-sided scholars indignantly attacked his wayward "misreadings" and flagrant anachronisms. At present, there is a similar (...) controversy raging around the figure of Jacques Derrida, whose influence on literary critics—mainly the Yale school of Geoffrey Hartman, Harold Bloom and J. Hillis Miller— occupies the forefront of debate in current theoretical exchange. Apart from all the sideshow of polemics, this parallel with Empson is a useful jumping-off point for an approach to Derrida and the implications of his writing. Empson opened up the literary text to a practice of reading which released as many ambiguities, overtones, and hints of recondite meaning as the analyst could reasonably claim to find in it. Reason, or commonsense judgment, still played an arbitrating role, since Empson wanted his readings at least to match something in the credible intention—at whatever "unconscious" level—of the author concerned. Subsequently, Empson has taken issue with the American New Critics on precisely this ground of authorial intention. Where they have dismissed all such considerations as outside the critic's proper interest or competence—treating the text as a "verbal icon," detached from any speculative background of motive or intent—Empson has come out in sturdy defense of "intentionalist" readings, based on available evidence of what the poet was trying to express. In other words, Empson, for all his dazzling inventiveness, held to a notion of the author as (implicitly) a self-possessed creator of meanings, one whose intentions demand critical respect, however broadly that requirement is to be interpreted in practice. Anglo-American criticism 242 Christopher Norris243 has lately been much preoccupied with the question of whether—or exactly how far—an author's original "meaning" can be recovered by close attention to his text. E. D. Hirsch's Validity in Interpretation is a classic if long-winded statement of the conservative view: that the critic's obligation is to come as close as possible to establishing what an author most probably meant in using language as. he did.3 The discipline involved is partly a matter of historical semantics (drawing a limit or "horizon" of possible meanings in context), and partly a matter of interpretative tact and sympathy. Hirsch grounds his argument on the Kantian premise that a text is in some sense the surrogate voice of its author, and that texts must therefore be treated, like people, as ends in themselves, and not means toward the critic's display of self-advertising brilliance. All the same, Hirsch has to acknowledge that authorial intention, as such, is beyond the grasp of this reconstructive program, which offers at best a kind of inferential yardstick for narrowing down the range of semantic potential. The problem which Hirsch never quite gets to grips with, despite his elaborate argumentation, is the fact that texts come across to us always from a distance of time, of experience or culture, which makes their meaning more or less opaque and problematic. The author is not simply there in the text, a self-authenticating "voice" of intent, as Hirsch (in his more sanguine moments) would have us believe. One might expect some such assurance from the homely narrative address of a novelist like Fielding, or the intimate soul-baring style of Wordsworth's poetry. Yet Fielding is as cunning a narrative tactician as any, his "voice" a shifting multitude of ironies and ploys; while Wordsworth manages a complex and selective rhetoric of memory which (as recent critics have shown) by no means communicates the "unmediated vision" of purely personal address. Hirsch yields a hostage to the relativist case by proposing a distinction between "meaning" (that which inheres in the text, and which the critic is duty-bound to preserve), and "significance" (the purely associative values which change with the passage of time and make room for rival or updated interpretations...

Christopher Norris is Emeritus professor at Cardiff University. Recently, he began to address philosophical questions through poetry. In his paper, he explains why. Rather than expressing definite ideas in an elegant way, poetry can be intended as a process from which new ideas (also philosophical ones) can emerge. The result are a number of poems which cover a variety of issues, ranging from philosophy to politics, arts, history of ideas and science. Itinera has already begun to publish a few (...) of these poems in previous issues and is now presenting three of them on painters (Turner, Matisse, Magritte). (shrink)

This book is a revised and expanded edition of three lectures delivered by the author at Wake Forest University in 1979. Long out of print, in its new edition it should be a valuable resource for scholars and teachers of the philosophy of religion. The first two lectures, after a critique of the incompleteness of St. Thomas Aquinas's famous Five Ways of arguing for the existence of God, explore lesser-known resources of Aquinas's philosophical ascent of the mind to God: the (...) unrestricted dynamism of the human spirit as it reaches toward the fullness of being, and the strictly metaphysical ascent to God from finite to infinite, in the line of Aquinas's later, more Neoplatonically inspired, metaphysics of participation. The third, and most heavily revised, lecture is a critique of Whitehead's process philosophy, distinguishing Aquinas more sharply and critically from Whitehead than in the first edition. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Logic of the SiteAlain Badiou (bio)Translated by Steve Corcoran (bio) and Bruno Bosteels (bio)The Commune Is a Site 1. Ontology of the CommuneTake any world whatsoever. A multiple that is an object of this world—whose elements are indexed by the transcendental of this world—is a site, if it happens to count itself within the referential field of its own indexation. Or again: a site is a multiple that (...) happens to behave in the world with regard to itself as with regard to its elements, in such a way as to be the support of being of its own appearance.Even if the idea is still obscure, we can begin to see its content: a site is a singularity, because it convokes its being in the appearing of its own multiple composition. It makes itself, in the world, the being-there of its being. Among other consequences, the site gives itself an intensity of existence. A site is a being that happens to exist by itself.We will ask: can we give a more concrete idea of what a site is? Is there a site?Let us consider the world "Paris at the end of the Franco-Prussian War of 1870." We are in the month of March 1871. After a semblance of resistance, and shot through with fear of revolutionary and worker Paris, the interim government of bourgeois "Republicans" capitulates to Bismarck's Prussians. In order to consolidate this political "victory"—very comparable to Petain's reactionary revenge in 1940 (where preferring an arrangement with the external enemy to exposure to the internal enemy)—it has an assembly with a royalist majority hastily elected by a frightened rural world, an assembly that sits in Bordeaux.Led by Thiers, the government hopes to take advantage of the circumstances to annihilate the political capacity of the workers. But on the Parisian front, the proletariat is armed in the form of a National Guard, owing to its having been mobilized during the siege on Paris. In theory the Parisian proletariat has many hundreds of cannons at its disposition. The "military" organism of the Parisians is the Central Committee, at which assemble the delegates of the various battalions of the National Guard, battalions [End Page 141] that are in turn linked to the great working-class quartiers of Paris—Montmartre, Belleville, and so forth.Thus we have a divided world whose logical organization—what in philosophical jargon could be called its transcendental organisation—reconciles intensities of political existence according to two sets of antagonistic criteria. Concerning the representative, electoral, and legal dispositions, one cannot but observe the preeminence of the Assembly of traditionalist Rurals,1 Thiers's capitulard government, and the officers of the regular army, who, having been licked without much of a fight by the Prussian soldiers, dream of doing battle with the Parisian workers. That is where the power is, especially as it is the only power recognized by the occupier. On the side of resistance, political intervention, and French revolutionary history, there is the fecund disorder of Parisian worker organizations, which intermingles with the Central Committee of the twenty quartiers, the Federation of Syndicate Chambers, a few members of the International, local military committees. In truth, the historical consistency of this world, which had been separated and disbanded [délié] owing to the war, is held together only by the majority conviction that no kind of worker capability for government exists. For the vast majority of people, including often the workers themselves, the politicized workers of Paris are simply incomprehensible. These workers are the inexistent aspect [l'inexistant propre] of the term "political capacity" in the uncertain world of the spring of 1871. But for the bourgeoisie they are still too existent, at least physically. The government receives threats from the stock exchange of this sort: "You will never have financial operations if you do not get rid of these reprobates." First up then, an imperative task, and a seemingly easy one to carry out: disarm the workers and, in particular, recuperate the cannons spread throughout working-class Paris by the military committees of the National Guard. It is this initiative that will make... (shrink)

This text is a reply to some of the more doctrinaire beliefs that pass for "radical" thinking. For the most part, Norris argues, these ideas are based on a false understanding of crucial episodes in their own pre-history.

In this commentary, I consider Schmitt's cross-cultural investigation of sociosexuality from a comparative perspective. I argue that such a perspective lends support to an evolutionary explanation of a number of Schmitt's findings, including universal sex differences in sociosexuality and the sensitivity of mating behavior to contextual variables such as sex ratio.

Quillen [17] introduced model categories as an abstract framework for homotopy theory which would apply to a wide range of mathematical settings. By all accounts this program has been a success and—as, e.g., the work of Voevodsky on the homotopy theory of schemes [15] or the work of Joyal [11, 12] and Lurie [13] on quasicategories seem to indicate—it will likely continue to facilitate mathematical advances. In this paper we present a novel connection between model categories and mathematical logic, inspired (...) by the groupoid model of (intensional) Martin–Löf type theory [14] due to Hofmann and Streicher [9]. In particular, we show that a form of Martin–Löf type theory can be soundly modelled in any model category. This result indicates moreover that any model category has an associated “internal language” which is itself a form of Martin-Löf type theory. This suggests applications both to type theory and to homotopy theory. Because Martin–Löf type theory is, in one form or another, the theoretical basis for many of the computer proof assistants currently in use, such as Coq and Agda (cf. [3] and [5]), this promise of applications is of a practical, as well as theoretical, nature. This paper provides a precise indication of this connection between homotopy theory and logic; a more detailed discussion of these and further results will be given in [20]. (shrink)

Specifically, basic categories of classes and categories of classes are axiomatized and shown to provide models of the aforementioned set theories. Finally, models of these theories are constructed in the category of (...) ideals. (shrink)
