Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a proposal along these lines first described by Jordan (1986) which involves the use of recurrent links in order to provide networks with a dynamic memory. In this approach, hidden unit patterns are fed back to themselves: (...) the internal representations which develop thus reflect task demands in the context of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands: indeed, in this approach the notion of memory is inextricably bound up with task processing. These representations reveal a rich structure, which allows them to be highly context‐dependent, while also expressing generalizations across classes of items. These representations suggest a method for representing lexical categories and the type/token distinction. (shrink)

Jeffrey Barrett presents the most comprehensive study yet of a problem that has puzzled physicists and philosophers since the 1930s.

“The Nature of Belief Systems” sets forth a Hobson's choice between rule by the politically ignorant masses and rule by the ideologically constrained—which is to say, the doctrinaire—elites. On the one hand, lacking comprehensive cognitive structures, such as ideological “belief systems,” with which to understand politics, most people learn distressingly little about it. On the other hand, a spiral of conviction seems to make it difficult for the highly informed few to see any aspects of politics but those that confirm (...) the cognitive structures that organize their political perceptions. This is a troubling situation for any consequentialist democratic political theory, according to which what is crucial is the electorate's (and subsidiary decision makers') ability to make informed policy judgments, not their possession of willful but uninformed political “attitudes.” Any political theorist who does not take democracy to be an end in itself (regardless of its consequences) should be concerned about Converse's findings.

In “Popper, Weber, and Hayek,” I claimed that the economic and political world governed by social democracy is too complex to offer hope for rational social‐democratic policy making. I extrapolated this conclusion from the claim, made by Austrian‐school economists in the 1920s and 30s, that central economic planning would face insurmountable “knowledge problems.” Israel Kirzner's Reply indicates the need to keep the Austrians’ cognitivist argument conceptually distinct from more familiar incentives arguments, which can tacitly reintroduce the assumption of omniscience against (...) which the Austrian economists rebelled. Callahan's Reply illustrates the need to keep in mind the hypothetical, conditional nature of economic arguments. Notturno's Reply changes the subject by asserting the intrinsic value of social‐democratic participation, regardless of its outcomes—even while, like Talisse's Reply, ignoring the evidence that public ignorance and elite dogmatism probably can't be mitigated by more information or by appeals to be open minded. And Hill focuses on the very real imperfections of market and other private‐sphere decision making, without weighing the shortcomings of the political alternatives. Markets and other private‐sphere decision arenas don't have to be perfect for them to improve upon public‐sector processes. In the latter, cognitive demands tend to be much greater, because of the divergence of modern social problems from the conditions that would have faced the hunter‐gatherers whose cognitive apparatus we have inherited.

I show that the quantum state ω can be interpreted as defining a probability measure on a subalgebra of the algebra of projection operators that is not fixed (as in classical statistical mechanics) but changes with ω and appropriate boundary conditions, hence with the dynamics of the theory. This subalgebra, while not embeddable into a Boolean algebra, will always admit two-valued homomorphisms, which correspond to the different possible ways in which a set of “determinate” quantities (selected by ω and the (...) boundary conditions) can have values. The probabilities defined by ω (via the Born rule) are probabilities over these two-valued homomorphisms or value assignments. So any universe of interacting systems, including those functioning as measuring instruments, can be modelled quantum mechanically without the projection postulate. (shrink)

Levinas and the Philosophy of Religion Jeffrey L. Kosky Reveals the interplay of phenomenology and religion in Levinas’s thought. "Kosky examines Levinas’s thought from the perspective of the philosophy of religion and he does so in a way that is attentive to the philosophical nuances of Levinas’s argument.... an insightful, well written, and carefully documented study... that uniquely illuminates Levinas’s work." —John D. Caputo For readers who suspect there is no place for religion and morality in postmodern philosophy, (...) class='Hi'>Jeffrey L. Kosky suggests otherwise in this skillful interpretation of the ethical and religious dimensions of Emmanuel Levinas’s thought. Placing Levinas in relation to Hegel and Nietzsche, Husserl and Heidegger, Derrida and Marion, Kosky develops religious themes found in Levinas’s work and offers a way to think and speak about ethics and morality within the horizons of contemporary philosophy of religion. Kosky embraces the entire scope of Levinas’s writings, from Totality and Infinity to Otherwise than Being, contrasting Levinas’s early religious and moral thought with that of his later works while exploring the nature of phenomenological reduction, the relation of religion and philosophy, the question of whether Levinas can be considered a Jewish thinker, and the religious and theological import of Levinas’s phenomenology. Kosky stresses that Levinas is first and foremost a phenomenologist and that the relationship between religion and philosophy in his ethics should cast doubt on the assumption that a natural or inevitable link exists between deconstruction and atheism. Jeffrey L. Kosky is translator of On Descartes’ Metaphysical Prism: The Constitution and the Limits of Onto-theo-logy in Cartesian Thought by Jean-Luc Marion. He has taught at Williams College.

The call for a narrative medicine has been touted as the cure-all for an increasingly mechanical medicine. It has been claimed that the humanities might create more empathic, reflective, professional and trustworthy doctors. In other words, we can once again humanise medicine through the addition of humanities. In this essay, I explore how the humanities, particularly narrative medicine, appeals to the metaphysical commitments of the medical institution in order to find its justification, and in so doing, perpetuates a dualism of (...) humanity that would have humanism as the counterpoint to the biopsychosociologisms of our day.

This article suggests an iconic turn in cultural sociology. Icons can be seen, it is argued, as symbolic condensations that root social meanings in material form, allowing the abstractions of cognition and morality to be subsumed, to be made invisible, by aesthetic shape. Meaning is made iconically visible, in other words, by the beautiful, sublime, ugly, or simply by the mundane materiality of everyday life. But it is via the senses that iconic power is made. This new approach to meaning (...) is compared with others — with materialism, semiotics, aestheticism, moralism, realism, and spiritualism. (shrink)

We are concerned here with explaining how successful rule-following behavior might evolve and how an old evolved rule might come to be successfully used in a new context. Such rule-following behavior is illustrated in the transitive judgments of pinyon and scrub-jays (Bond et al., Anim Behav 65:479–487, 2003). We begin by considering how successful transitive rule-following behavior might evolve in the context of Skyrms–Lewis sender–receiver games (Lewis, Convention. Harvard University Press, Cambridge, 1969; Skyrms, Philos Sci 75:489–500, 2006). We then consider (...) two ways that an agent might come to use an old evolved rule in a new context. The first involves the agent evolving successful dispositions for one concrete type of experience, then associating a new type of experience with the old evolved dispositions. The second involves the agent evolving dispositions that represent a general inferential schema, then composing these dispositions with others in a way that allows the agent to make inferences concerning a new concrete type of experience.

Th is article examines the extent to which spaces are structuring influences on, or targets of, action. Two factors and their interactions are presented: the extent to which a space is 1) maintained and 2) used. As these factors increase in strength, the structural influences of a space increase while agential opportunities are diminished. Conversely, as spaces become dilapidated and abandoned, structural forces are weakened and the potential for creative action heightens. These spaces can be conceptualized as elements of the (...) ‘residual landscape’: spaces left behind by socio-historical processes and practices. Special cases are considered where the factors are inversely related and issues of structure and agency are complicated. A brief case study serves to illustrate each type of spaceand the factors which operate therein. (shrink)

Deontological (as opposed to consequentialist) liberals treat freedom of action as an end in itself, not a means to other ends. Yet logically, when one makes a deliberate choice, one treats freedom of action as if it were not an end in itself, for one uses this freedom as a means to the ends one hopes to achieve through one's action. The tension between deontology and the logic of choice is reflected in the paradoxical nature of the ?right to do (...) wrong?; and in Rawls's unsuccessful attempts to justify to acting agents their interest in such a right, embodied in his conception of agents as ?self-validating sources of claims.? A self-validating source of claims is akin to God as envisioned by voluntarist theologians such as Ockham. Leibniz's critique of voluntarism, then, is applicable to the Rawlsian subject: like the voluntarist God, she would be unable to act if it were indeed the case that her action validated itself.

Consider a group of people whose preferences satisfy the axioms of one of the current versions of utility theory, such as von Neumann-Morgenstern (1944), Savage (1954), or Bolker-Jeffrey (1965). There are political and economic contexts in which it is of interest to find ways of aggregating these individual preferences into a group preference ranking. The question then arises of whether methods of aggregation exist in which the group’s preferences also satisfy the axioms of the chosen utility theory, and in (...) which at the same time the aggregation process satisfies certain plausible conditions (e.g., the Pareto conditions below).

The first claim in the target article was that there is as yet no transparent, causal account of the relations between consciousness and brain-and-behaviour. That claim remains firm. The second claim was that the contents of consciousness consist, psychologically, of the outputs of a comparator system; the third consisted of a description of the brain mechanisms proposed to instantiate the comparator. In order to defend these claims against criticism, it has been necessary to clarify the distinction between consciousness-as-such and the (...) contents of consciousness, to widen the description of the neural machinery instantiating the comparator system, and to clarify the relationship between the contents of consciousness in the here-and-now and episodic memory.

In lieu of an abstract, here is a brief excerpt of the content:American Journal of Philology 121.4 (2000) 655-658 [Access article in PDF] RONALD MELLOR. The Roman Historians. London and New York: Routledge, 1999. x + 212 pp. Paper, $21.99. This is a textbook, the purpose of which is to provide "an introduction to the masterpieces of Roman historical and biographical writing" (ix). Although the question of the usefulness of these writings to the modern historian is not overlooked, the principal (...) concern is "to take Roman historical writing on its own terms" (196). Very little background is assumed, and no Latin (by "Roman" the title refers to works composed in Latin, regardless of subject matter: hence Nepos' Pelopidas is in, but Polybius, Diodorus, and Dio are out, except [End Page 655] as background or comparanda). The author is a distinguished Tacitean scholar, and his style is at once clear and attractive. His survey begins with the origins of Roman historiography, with special attention given to what can be known of the early annalists, to the contribution of the elder Cato, and especially to Cicero's verdict on the efforts of them all. Fine chapters on Sallust and Livy follow, and, naturally in view of the author's predilections, a long and adoring chapter on Tacitus. Ammianus Marcellinus also gets his due, in a chapter that is actually longer than Sallust's. A single chapter is devoted to Roman biography (Nepos, Tacitus once more, Suetonius and the Historia Augusta), another to autobiography (Caesar, Augustus' Res Gestae). An appraisal of the Roman achievement, and its influence, concludes the book. The strengths of Mellor's treatment of every author and every subject are many. He is keenly attentive to ancient expectations and the particular context of the central authors whose works he examines; he is especially good at fitting the purposes of a historian's writings to the historian's actual circumstances. He constantly reminds the reader of the differences between Roman and modern conceptions of historical writing. He appreciates the importance of style in appraising and understanding ancient historiography. And he makes frequent acute observations that will save instructors who use this book a good deal of time and explanation, as when he remarks of Tacitean characterization that, "since he could not easily explain ambiguities, they are expressed as contradictions" (104). In sum, then, the volume is intelligent, congenial, and will be very serviceable in courses dealing with Roman history or with historiography.It is inevitable, when anyone reviews a work of such scope, that there will be quibbles. Let me record a few of mine. Students are likely to be misled by the use of "plebeian" on p. 20. To say that, in 52 B.C., Clodius Pulcher was "Caesar's man," in contrast to Milo who by implication was Pompey's (31), is to get it wrong (cf. W. Jeffrey Tatum, The Patrician Tribune [Chapel Hill 1999] 214-15, 234-35). Since Caesar reached the senior magistracies at the earliest possible age, it is not clear to me that "his early career progressed slowly" (171). The view of Roman marriage represented on p. 69 is somewhat old-fashioned, and, along those lines, it is anachronistic to speak of "the bigamous marriage celebration of the empress Messalina" (90: Tacitus' Narcissus is accurate when at Ann. 11.30 he asks Claudius: an discidium... tuum nosti?). One does not often hear, these days, of the "clinical objectivity of Thucydides" (44). In discussing Sallust's attraction to Thucydides (43-45), it might have been helpful to discuss the (admittedly not uncomplicated) issue of Atticism in late-first-century Rome. I am less convinced than Mellor is that the speech of Sallust's Caesar constitutes the historian's "plea for common sense" (38) in the midst of the triumviral proscriptions; after all, Sallust wrote Cato's speech as well. It can hardly be true, if only in view of Pliny's keen interest in his friend's literary productivity, that Suetonius' Lives "is a book written by and for the equestrian" (152), nor do I think the description of the imperial equestrian order that is given on [End Page 656] that page...

He argues that, in comparison with the violence and narrowness of any given social order, anomie may well be (...) preferable, and, in any case, may be no more than another name for quietism.

This collection of essays by some of the leading scholars in religion in North America explores the complex relationship between the academic study of religion and personal religious experience. Each volume in this new series explores a central theme or topic that has informed the religious experiences of humanity throughout history. Each theme is discussed from a comparative perspective using a variety of methodological approaches.

It is argued that the measurement problem reduces to the problem of modeling quasi-classical systems in a modified quantum mechanics with superselection rules. A measurement theorem is proved, demonstrating, on the basis of a principle for selecting the quantities of a system that are determinate (i.e., have values) in a given state, that after a suitable interaction between a systemS and a quasi-classical systemM, essentially only the quantity measured in the interaction and the indicator quantity ofM are determinate. The theorem (...) justifies interpreting the noncommutative algebra of observables of a quantum mechanical system as an algebra of “beables,” in Bell's sense. (shrink)

A system of environmental ethics recently developed by Lawrence Johnson may be used to analyze the moral implications of biological control. According to this system, entities are morally relevant when they possess well-being interests (i.e., functions or processes that can be better or worse in so far as the entity is concerned). In this formulation of ethical analysis, species and ecosystems are morally relevant because they are not simply aggregates of individuals, so their processes, properties, and well-being interests are not (...) reducible to the sum of their individual members. Following Johnson's thesis, species and ecosystems have morally relevant interests in surviving and maintaining themselves as integrated wholes with particular self-identities. This theoretical structure gives rise to a number of ethical criteria that are particularly relevant to biological control, which apply to the ecosystem (the extent to which it is large, native, unique, and integrated) and to the action being considered (the extent to which it is novel, omnipresent, monitored, reversible, and necessary). In these terms, it is evident that not all biological control efforts are ethically defensible. In general terms, natural biological control is most desirable, followed by augmentative strategies, classical approaches, and finally neoclassical biological control. Two specific cases (neoclassical biological control of rangeland grasshoppers and classical biological control of prickly pear cactus) illustrate the ethical concerns. Finally, it can be shown that formalized restrictions of biological control are necessary, given the unique properties of this technology. (shrink)

This dialogue concerns metasemantics and language cognition. It defends a Lewisian conception of languages as abstract entities (Lewis 1975), arguing that semantic facts are necessities (Soames 1984), and therefore not naturalistically reducible. It identifies spoken languages as idiolects, in line roughly with Chomskyan I-languages. It relocates traditional metasemantic indeterminacy arguments as indeterminacies of what language an agent speaks or cognizes. Finally, it aims to provide a theoretical analysis of the cognizing relation in terms of the agent's assigning certain meanings to (...) strings. (shrink)

This article defends what I call the atmospheric claim about trust: at least one form of trust manifests itself in human life in a manner that is like an atmosphere (generalized, ambient, and diffuse). I also provide a provisional defense of the claim that trust is a necessary condition for the thriving of something that matters to us. I offer a phenomenological sketch of existential trust. Existential trust is a primordial and atmospheric (generalized, ambient, and diffuse) manifestation of trust that (...) constitutes a fundamental way of being in relationship with the world as a whole such that one feels supportively upheld, vulnerably open, orientationally attuned, and demanded in relation to this world, with the overall effect of feeling at home in it.

The distinction and relationship between teaching creatively and teaching for creativity identified in the report from the National Advisory Committee on Creative and Cultural Education (NACCCE, 1999), is examined by focusing on empirical research from an early years school, known for its creative approach. The examination uses four characteristics of creativity and pedagogy identified by Peter Woods (1990): relevance, ownership, control and innovation, to show the interdependence of the NACCCE distinctions. We conclude that although the NACCCE distinction between teaching creatively (...) and teaching for creativity has been useful as an analytical tool, it may, at the same time, have dichotomised an integrated practice and we suggest that a more useful distinction for the study of creative pedagogies would be the relationship between teaching creatively and creative learning.

It is shown in this article that the two sides of an equation in the medieval Arabic algebra are aggregations of the algebraic “numbers” (powers) with no operations present. Unlike an expression such as our 3x + 4, the Arabic polynomial “three things and four dirhams” is merely a collection of seven objects of two different types. Ideally, the two sides of an equation were polynomials so the Arabic algebraists preferred to work out all operations of the enunciation to a (...) problem before stating an equation. Some difficult problems which involve square roots and divisions cannot be handled nicely by this basic method, so we do find square roots of polynomials and expressions of the form “A divided by B” in some equations. But rather than initiate a reconsideration of the notion of equation, these developments were used only for particularly complex problems. Also, the algebraic notation practiced in the Maghreb in the later middle ages was developed with the “aggregations” interpretation in mind, so it had no noticeable impact on the concept of polynomial. Arabic algebraists continued to solve problems by working operations before setting up an equation to the end of the medieval period. (shrink)

Mettre en rapport des textes de Hegel sur l’amour érotique avec quelques passages du penseur romantique Friedrich Schlegel permet de mettre en relief la méfiance hégélienne à l’égard du désir sexuel. Selon l’échelle hiérarchique de désirs chez Hegel, le désir érotique fait preuve d’un déséquilibre entre le sujet désirant et l’objet désiré, ce qui est typique d’un rapport purement naturel et non spirituel. C’est dire que la connaissance charnelle, avec son objet dénué de Soi propre, représente pour Hegel une forme (...) inférieure de savoir. L’inégalité sujet-objet propre à l’amour érotique n’est dépassée que par la participation à la substance éthique, ce qui exige la reconnaissance réciproque de consciences de soi égales. Dans ce contexte, il s’agit du mariage. Juxtaposing some of Hegel’s texts on erotic love with certain passages from the romantic thinker Friedrich Schlegel throws light on Hegel’s problematic relationship with sexual desire. According to his hierarchy of types of desire, erotic desire betrays an imbalance between the desiring subject and the object of desire, typical of a purely natural, non-spiritual relation. This means that carnal knowledge, with its self-less object, represents an inferior form of knowing. The inequality between subject and object, inherent in erotic love, is only surpassed through participation in the ethical substance, requiring the reciprocal recognition of equal self-consciousnesses. In the present context, this means marriage. (shrink)

Nucleosome positioning is proposed to have an essential role in facilitating the regulated transcription of eukaryotic genes. Some transcription factors can bind to DNA when it is appropriately wrapped around the histone core, others cannot bind due to the severe deformation of DNA structure. The staged assembly of nucleosomes and positioning of histone‐DNA contacts away from promoter elements can facilitate the access of transcription factors to DNA. Positioned nucleosomes can also facilitate transcription through providing the appropriate scaffolding to bring regulatory (...) factors bound at dispersed sites into juxtaposition. (shrink)

The most common form of the CO2‐fixing enzyme rubisco is a form I enzyme, heretofore found universally in oxygenic phototrophs (cyanobacteria and plastids) and widely in proteobacteria. Two groups(1–4), however, now report that in dinoflagellate plastids the usual form I rubisco has been replaced by the distantly related form II enzyme, known previously only from anaerobic proteobacteria. This raises the important question of how such an oxygensensitive rubisco could function in an aerobic organism. Moreover, the dinoflagellate rubisco has unusual molecular (...) properties: it is encoded as a polyprotein, by nuclear (rather than plastid) genes, and these genes contain noncanonical spliceosomal introns. The nuclear location and alphaproteobacterial affinity of dinoflagellate rubisco genes hint at a possible mitochondrial origin and highlight the extraordinary richness of lateral gene transfers, both between and within organisms, that have occurred during rubisco evolution.

This essay develops our meta-logical interpretation of Leibniz’s formal theory of contingency by taking up two additional issues not fully addressed in our earlier efforts. The first issue concerns the relationship between Leibniz’s formal theory of contingency and his views on species and essentialism. The second issue concerns the relationship between Leibniz’s formal theory of contingency and the modal status of the actual world.
