Each of the homeotic genes of the bithorax complex of Drosophila defines the identities of more than one body segment. The mechanisms by which this occurs have been elusive. In a recent report, Castelli‐Gair and Akam(1) analyze in detail the control of parasegment 5 and parasegment 6 identities by the bithorax complex gene Ubx. Their results indicate that differences in the spatial and temporal expression patterns of Ubx are critical in determining differences between these parasegments. However, dose effects observed by (...) others indicate that parasegment‐specific differences in the level of Ubx expression are also important. For the other BX‐C genes, parasegment‐specific expression of protein isoforms, or combinatorial control dependent on the expression patterns of other spatially restricted regulators, may also play a role.

A collection of anecdotes that articulate the inspirations behind the development of the Frank/Suzuki Performance Aesthetics, an actor training system.

In this paper I add credence to Linda Zagzebski's (1994) diagnosis of Gettier problems (and the current trend to abandon the standard analysis) by analyzing the nature of luck. It is widely accepted that the lesson to be learned from Gettier problems is that knowledge is incompatible with luck or at least a certain species thereof. As such, understanding the nature of luck is central to understanding the Gettier problem. Thanks by and large to Duncan Pritchard's seminal work, Epistemic (...) Luck, a great deal of literature has been developed recently concerning the nature of luck and anti-luck epistemology. The literature, however, has yet to explore the very intuitive idea that luck comes in degrees. I propose that once luck is recognized to admit degrees even the slightest non-zero degree (of the relevant sort) precludes knowledge. Connecting this to Zagzebski's thesis, I propose that a given theory of warrant must guarantee truth in order to avoid Gettier counterexamples (or subsequently deny that warrant bears any relationship to the truth whatsoever), simply because a sufficient standard analysis of knowledge cannot allow for knowledge that is even marginally lucky.

The notion of risk plays a central role in economics, finance, health, psychology, law and elsewhere, and is prevalent in managing challenges and resources in day-to-day life. In recent work, Duncan Pritchard (2015, 2016) has argued against the orthodox probabilistic conception of risk on which the risk of a hypothetical scenario is determined by how probable it is, and in favour of a modal conception on which the risk of a hypothetical scenario is determined by how modally close it (...) is. In this article, we use Pritchard’s discussion as a springboard for a more wide-ranging discussion of the notion of risk. We introduce three different conceptions of risk: the standard probabilistic conception, Pritchard’s modal conception, and a normalcy conception that is new (though it has some precursors in the psychological literature on risk perception). Ultimately, we argue that the modal conception is ill-suited to the roles that a notion of risk is required to play and explore the prospects for a form of pluralism about risk, embracing both the probabilistic and the normalcy conceptions.

Ian Duncan’s Human Forms and Devin Griffiths’s Age of Analogy attempt to illuminate inter­actions between evolutionary theories and literature from the late eighteenth century up through the nineteenth century. They do not advance knowledge about this subject. Both authors treat evolution as a semi-fictional construction that owes more to literary inspiration than to the scientific method, and they reduce literature to a battleground for ideological forces. They write using dense terminology, shifting rhetoric, and flights of verbal performance that obscure (...) their claims. In all these respects, they are representative of the field “science and literature”-and particularly of the subfield that studies evolution and literature. I analyze the history of this subfield of literary scholarship and attempt to explain how it developed into its present form. The subfield was founded in the 1980s on the basis of poststructuralist theory and has never escaped the core assumptions of that theory: our minds cannot reach outside culture; our thoughts, behaviors, and ideas about the world are primarily the result of our culture; some cultural traditions are oppressive while others are liberating; and the meaning of texts cannot be determined. Though Duncan and Griffiths represent the highest level of schol­arship on evolution and literature, I argue that they fail their fascinating subject by offering very little that is new within their own field, and nothing that is of value to other fields.

Duncan Foley’s Unholy Trinity: Labor, capital, and land in the new economy is the sixth in the series of Graz Schumpeter Lectures published by Routledge, all relatively slim volumes elucidating themes arguably related to Schumpeter, if just peripherally, and that usually summarize major arguments of the authors (previous authors were Stanley Metcalfe, Brian Loasby, Nathan Rosenberg, Ian Steedman, and Erich Streissler). In this one, which deals with questions of induced technological change in several sections, Foley attempts to provide an (...) integration of ideas that have evolved through his varied career, from high general equilibrium theorist (Foley, 1967), through deep student of Marxian economics (Foley, 1986), to complexity theorist (Foley, 1994; for more detailed discussion of his personal and intellectual path see Colander et al, 2004, Chapter 7). A central argument is that the classical political economists, not just Marx but also Adam Smith and Malthus with Ricardo (largely lumped together in his analysis), developed ideas that are well suited to representation and understanding using the methods of modern complexity economics, themes of dynamic out-of-equilibrium selforganization in systems with boundedly rational agents, in contrast to the requirements for full Walrasian general equilibrium that he studied early in his career.

Historical records show that there was no real concept of probability in Europe before the mid-seventeenth century, although the use of dice and other randomizing objects was commonplace. Ian Hacking presents a philosophical critique of early ideas about probability, induction, and statistical inference and the growth of this new family of ideas in the fifteenth, sixteenth, and seventeenth centuries. Hacking invokes a wide intellectual framework involving the growth of science, economics, and the theology of the period. He argues that the (...) transformations that made it possible for probability concepts to emerge have constrained all subsequent development of probability theory and determine the space within which philosophical debate on the subject is still conducted.

An expanded & revised version of Religion in an Age of Science. Three new chapters on physics & metaphysics in the 18th century and biology & theology in the 19th century. Other new sections included.

This truly philosophical book takes us back to fundamentals - the sheer experience of proof, and the enigmatic relation of mathematics to nature. It asks unexpected questions, such as 'what makes mathematics mathematics?', 'where did proof come from and how did it evolve?', and 'how did the distinction between pure and applied mathematics come into being?' In a wide-ranging discussion that is both immersed in the past and unusually attuned to the competing philosophical ideas of contemporary mathematicians, it shows that (...) proof and other forms of mathematical exploration continue to be living, evolving practices - responsive to new technologies, yet embedded in permanent facts about human beings. It distinguishes several distinct types of application of mathematics, and shows how each leads to a different philosophical conundrum. Here is a remarkable body of new philosophical thinking about proofs, applications, and other mathematical activities. (shrink)

Science is often thought of as a methodical but dull activity. But the finest science, the breakthroughs most admired and respected by scientists themselves, is characterized by elegance." "What does elegance mean in the context of science? Economy is a considerable part of it; creativity too. Sometimes, a suggested solution is so simple and neat that it elicits an exclamation of wonder from the observer. The greatest science, whether primarily theoretical or experimental, reflects a creative imagination." "In this book, the (...) distinguished physiologist and writer Ian Glynn explores some of the finest examples of elegance in science: the delightful simplicity of the laws discovered by Kepler and Newton in the motion of the planets; Galileo's experiments with an inclined plane; the remarkable work of Thomas Young on light; dazzling insights into the counterintuitive workings of our perception demonstrated by Richard Gregory and Vilayanur Ramachandran; and the several breakthroughs that led to Crick and Watson's unravelling of the structure and function of DNA. The result is a fascinating tour through some of the most important episodes in the history of science."--BOOK JACKET. (shrink)

The idea of elegance in science is not necessarily a familiar one, but it is an important one. The use of the term is perhaps most clear-cut in mathematics - the elegant proof - and this is where Ian Glynn begins his exploration. Scientists often share a sense of admiration and excitement on hearing of an elegant solution to a problem, an elegant theory, or an elegant experiment. The idea of elegance may seem strange in a field of endeavour that (...) prides itself in its objectivity, but only if science is regarded as a dull, dry activity of counting and measuring. It is, of course, far more than that, and elegance is a fundamental aspect of the beauty and imagination involved in scientific activity. Ian Glynn, a distinguished scientist, selects historical examples from a range of sciences to draw out the principles of science, including Kepler's Laws, the experiments that demonstrated the nature of heat, and the action of nerves, and of course the several extraordinary episodes that led to Watson and Crick's discovery of the structure of DNA. With a highly readable selection of inspiring episodes highlighting the role of beauty and simplicity in the sciences, the book also relates to important philosophical issues of inference, and Glynn ends by warning us not to rely on beauty and simplicity alone - even the most elegant explanation can be wrong.

This concise overview of the perception of Islam in eight of the most important German thinkers of the eighteenth and nineteenth centuries allows a new and fascinating investigation of how these thinkers, within their own bodies of work, often espoused contradicting ideas about Islam and their nearest Muslim neighbors. Exploring a variety of 'neat compartmentalizations' at work in the representations of Islam, as well as distinct vocabularies employed by these key intellectuals, Ian Almond parses these vocabularies to examine the importance (...) of Islam in the very history of German thought. Almond further demonstrates the ways in which German philosophers such as Hegel, Kant, and Marx repeatedly ignored information about the Muslim world that did not harmonize with the particular landscapes they were trying to paint – a fact which in turn makes us reflect on what it means when a society possesses 'knowledge' of a foreign culture.

The primary aim of this paper is to highlight, at least in short, how the resources of experimental philosophy could be fruitfully applied to the evidential problem of evil. To do this, we will consider two of the most influential and archetypal formulations of the problem: William L. Rowe’s article, “The Problem of Evil and Some Varieties of Atheism” (1979). and Paul Draper’s article, “Pain and Pleasure: An Evidential Problem for Theists” (1989). We will consider the relevance of experimental philosophy (...) to Rowe’s 1979 argument in §1 and to Draper’s 1989 argument in §2. But in addition to exploring how the resources of experimental philosophy might apply to the problem of evil, it is also worth exploring what broader empirical factors might contribute to people having the intuitions that have—from someone’s affective state to someone’s need for closure. In §3, we want to very briefly elucidate a few areas where the psychology of philosophy might be productively explored in future empirical research. (shrink)

In October 1924, The Physical Review, a relatively minor journal at the time, published a remarkable two-part paper by John H. Van Vleck, working in virtual isolation at the University of Minnesota. Van Vleck used Bohr's correspondence principle and Einstein's quantum theory of radiation to find quantum formulae for the emission, absorption, and dispersion of radiation. The paper is similar but in many ways superior to the well-known paper by Kramers and Heisenberg published the following year that is widely credited (...) to have led directly to Heisenberg's Umdeutung paper. As such, it clearly shows how strongly the discovery of matrix mechanics depended on earlier work on the application of the correspondence principle to the interaction of matter and radiation.

As a young bachelor of theology William of Ockham found himself under attack for—among other things—views he had expressed regarding the Aristotelian accident of quantity and the related question of Christ’s presence in the Eucharist. This essay focuses on Ockham’s conception of academic freedom as it was articulated in defense of his own position. Against fellow schoolmen who mistake their own magisterial opinions for settled Catholic dogma, Ockham insists on the latitude that is afforded scholars in matters that have not (...) yet been definitively determined by the Roman Church. Hence when it comes to the precise alignment of the eucharistic accidents, until such time as the Roman Pontiff hands down an official determination, Ockham contends that he is under no obligation to yield to the pressures of envious academics. The younger Ockham, who pointedly refrains from accusing his opponents of heresy, simply asks that they would exhibit the same restraint. (shrink)

L'évêque anglican Joseph Butler proclama, au XVIIIe siècle, que " la probabilité est le guide même de la vie ". Aujourd'hui, probabilités et statistiques ont envahi quasiment tous les domaines de nos vies privées et publiques. Les politiques gardent les yeux rivés sur les sondages, les organismes de retraite nous annoncent des années noires au vu des courbes démographiques, et dans l'intimité de nos salles de bains, perchés sur la balance, nous nous demandons si notre poids est conforme à la (...) moyenne. Dans le domaine scientifique, l'usage de la probabilité semble avoir détrôné un goût de la certitude plus cartésien : l'irruption de la mécanique quantique et de sa fameuse fonction d'onde a fait couler des fleuves d'encre philosophique. Mais une querelle d'interprétation continue à opposer deux conceptions irréductibles : selon l'une, la probabilité est une affaire foncièrement subjective qui relève essentiellement de l'état des croyances de chacun ; selon l'autre, elle est avant tout une question objective relative à la fréquence d'apparition de phénomènes dits aléatoires. De ce concept essentiel et délicat, Ian Hacking tente ici l'archéologie. Comment la probabilité a-t-elle pu devenir aussi envahissante, en politique comme en science, et qu'a-t-elle à voir avec l'opinion? Comment une notion apparemment aussi fugace est-elle devenue l'objet d'un calcul? Quels défis lance-t-elle au raisonnement et à la logique? Dans cette quête aux allures de roman policier, Pascal, Leibniz ou Huygens côtoient des politiques mettant en place un système de rentes à vie, des amateurs tentant de déceler dans des épidémies un ordre sous-jacent, des joueurs impénitents et des inconditionnels de la loterie.

We explore two special challenges indigenous peoples pose to the idea of sovereigns as trustees for humanity. The first challenge is rooted in a colonial history during which a trusteeship model of sovereignty served as an enabler of paternalistic colonial policies. The challenge is to show that the trusteeship model is not irreparably colonial in nature. The second challenge, which emerges from the first, is to specify the scope and nature of indigenous peoples’ sovereignty within the trusteeship model. Whereas the (...) interaction between states and foreign nationals is the locus of cosmopolitan law, the relationship between states and indigenous peoples is distinctive. In the ordinary cosmopolitan case, foreign nationals do not purport to possess legal authority. Indigenous peoples often do make such a claim, pitting their claim to authority against the state’s. We discuss how international law has attempted to come to grips with indigenous sovereignty by requiring states to include indigenous peoples in decision-making processes that affect their historical lands and rights. A crucial fault line in the jurisprudence, however, separates a duty to consult indigenous peoples from a duty to acquire their free, prior and informed consent. The latter but not the former recognizes that indigenous peoples possess a veto over state projects on their lands, in effect recognizing in them a limited co-legislative power. We focus on recent jurisprudence from the Inter-American Court of Human Rights, and consider whether either the duty to consult or FPIC are enough to dispel the shadow of the trusteeship model’s colonial past. We suggest that they are a move in the right direction, and that implicitly they represent international law’s recognition that states are no longer the sole bearers of sovereignty at international law. In limited circumstances, international law recognizes indigenous peoples as sovereign actors. (shrink)
