Stalk‐eyed flies of the family Diopsidae exhibit a unique form of hypercephaly, which has evolved under both natural and sexual selection. Male hypercephaly is used by female diopsids as an indicator of male quality. By choosing to mate with males expressing the most‐exaggerated hypercephaly, females can benefit both from the enhanced fertility of these males and the transmission of other heritable advantages to their offspring. Stalk‐eyed flies are close relatives of the model organism, Drosophila melanogaster. We have shown that similar (...) genetic and cellular mechanisms regulate the initial development of the head capsule in fruitflies and diopsids. The great diversity of stalk‐eyed fly species, exhibiting varying degrees of hypercephaly and sexual dimorphism, constitutes a major advantage for comparative studies of their development and evolution.

Sexually‐selected exaggerated traits tend to be unusually reliable signals of individual condition, as their expression tends to be more sensitive to nutritional history and physiological circumstance than that of other phenotypes. As such, these traits are the foundation for many models of sexual selection and animal communication, such as “handicap” and “good genes” models. Exactly how expression of these traits is linked to the bearer's condition has been a central yet unresolved question, in part because the underlying physiological mechanisms regulating (...) their development have remained largely unknown. Recent discoveries across animals as diverse as deer, beetles, and flies now implicate the widely conserved insulin‐like signaling pathway, as a common physiological mechanism regulating condition‐sensitive structures with extreme growth. This raises the exciting possibility that one highly conserved pathway may underlie the evolution of trait exaggeration in a multitude of sexually‐selected signal traits across the animal kingdom.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Chaucer’s Ovidian Arts of LoveWarren GinsbergChaucer’s Ovidian Arts of Love, by Michael A. Calabrese; x & 162 pp. Gainesville: University of Florida Press, 1994, $29.95.Michael Calabrese’s Chaucer’s Ovidian Arts of Love is a welcome re-examination of Chaucer’s interest in Ovid. Calabrese contends that Ovid’s entire “oeuvre,” including the poems of exile, determined Chaucer’s attitude toward him. The thesis is significant, both in itself and for the questions it (...) raises about medieval intertextuality.By the fourteenth century, accounts of Ovid’s life usually prefaced his poetic texts; in academic commentaries, an “accessus” also considered the ethical utility of the poem. Calabrese combines these two aspects of the textual tradition: he argues the trajectory of Ovid’s biography established a moral framework which determined his reception. There were, in effect, two Ovids, the poet of love and the poet of exile, the latter apologizing in old age for the indiscretions of his youth.Even as Ovid became a cornerstone of the school curriculum, however, many continued to censure him. While these anti-Ovidian comments and the academic commentaries share the same moral universe, they seem to be at odds. Calabrese explains the tension on theoretical grounds: in exile the Ovid of the commentators recanted his faith in rhetoric’s ability to create the world; his poetry now seeks to provide refuge amid the flux of a darker universe. For Christian moralists, this insight pointed to its own limitations: stability resides not in poetry but with the Word.For Calabrese, Chaucer read Ovid within this matrix of concerns. The rest of Chaucer’s Ovidian Arts of Love consists of extended readings of the Troilus, the “Wife of Bath’s Prologue and Tale,” and the “Retraction” that ends the Canterbury Tales. In the Troilus, Chaucer’s characters attempt to regulate an unpredictable Ovidian universe by means of an Ovidian rhetoric of love, in which art triumphs over every circumstance. When this rhetoric proves empty, Troilus abandons it entirely, aligning himself with the unvarying verities of Christian salvation. Pandarus and Criseyde, however, merely switch Ovids: the “praeceptor amoris” becomes the instructor who teaches how to survive the vacillations of Fortune. In making the Wife of Bath, Chaucer again set different Ovids against one another. Misogynists looked to the Ars Amatoria to support their contention that women were lecherous and deceitful. But Alice empowers herself by redeploying the stratagems of the third book of the Ars to gain control of men; she counters male mastery of her body by authoring a new art of love. The Wife combats the antifeminist tradition not only by using the same texts that constituted it, but by appropriating the commentators’ prerogative of rewriting authors to suit their purposes. Finally, Calabrese argues that Chaucer, reflecting on his own life as a fiction maker, turned again to Ovid’s biography; the Tristia and Ex Ponto, Ovid’s “apologiae pro poetria sua,” provided Chaucer an admonitory model when he composed his “Retraction.” [End Page 180]Throughout his book, Calabrese maintains a dialogue with John Fyler, who argued in Chaucer and Ovid that the English poet “took Ovid straight.” Calabrese is right to say that during the Middle Ages, “Ovid” meant both his poems and the accompanying commentary. But the fact that these materials are part of the manuscript record should not exempt them from critical scrutiny, nor does it constitute a sufficient account of their historicity. Academic strategies to rehabilitate Ovid need themselves to be interpreted, not least because Ovid anticipates their attempts to read his amatory poems as if they were some kind of “Eudam(on)ian” ethics. Granting the importance of the “vitae ovidii,” one nevertheless suspects Ovid’s fate meant something different to Chaucer in the 1380s from what it did in the 1390s.Moreover, by itself appealing to contemporary interpretation is neither more nor less helpful than Fyler’s approach in assessing how Chaucer responded to Ovid. To my mind, Calabrese under-reads Ovid in the same way the commentaries under-read him: both compartmentalize Ovid’s irony; neither allows that the poet might subvert every premise even as he urges its adoption. Chaucer, however, strikes... (shrink)

Eric Scerri has argued that chemists using ab initio calculations pursue a partial reduction of chemistry to physics, while accepting that full reduction (through axiomatization) is impractical. He characterizes this view as Popperian and naturalistic. However, Popper's position on reduction is not naturalistic, as he rejected axiomatization for different reasons.

In this volume, Swedish visionary Emanuel Swedenborg discusses marriage from a spiritual perspective -- the ways in which men and women relate to each other both in this world and in the afterlife, and how marriages in heaven can either grow into a state of bliss and unity or wither away as partner discover their incompatibilities and seek their true soulmates. Swedenborg includes his perspective on sexual relationships in this world, both in and out of wedlock, and how the choices (...) that we make affect our spiritual development. Interwoven with the text are numerous examples of his experiences in heaven. This edition is a reprint of a 1915 translation by Samuel M. Warren, revised by Louis H. Tafel. (shrink)

Some authors, such as Felix Oppenheim, Will Kymlicka and Ronald Dworkin, have claimed that the notion of degrees of freedom makes no sense, or in any case plays no part in a liberal theory of justice. Their various arguments can be classed as ontological, epistemological and normative, given that they aim to show, respectively, that there is no such thing as overall freedom, that overall freedom cannot be measured, and that overall has no normative importance. For these authors the freedom (...) of a person to do a specific thing is the only kind of freedom that exists, or the only kind that we can know about, or the only kind that matters. In answer to the ontological objection, it can be shown that there is such a thing as overall freedom if there is such a thing as specific freedoms, given that one can quantify over each of the elements of the triadic relation in which a specific freedom consists. The normative objection is answered in chapters 2 and 3, and the epistemological objection in chapters 7-9. (shrink)

ABSTRACT This paper is an account of a response to a well‐intentioned and genuinely naive question concerning the nature of ‘applied philosophy’. It indicates differing points of view concerning the nature of philosophy and what one might or might not expect from it. It tries to synthesise these points of view into a position that sees philosophy as continuous with that attitude of mind that was epitomised by Socrates, an attitude of mind which is directed to every aspect or dimension (...) of human life. The notion of the enquiring activist is borrowed to encapsulate this attitude as a valuable goal of ‘applied philosophy’. (shrink)

Hans Kelsen and Max Weber are conventionally understood as initiators not only of two distinct and opposing processes of concept formation, but also of two discrete and contrasting theoretical frameworks for the study of law. _The Foundation of the Juridical-Political: Concept Formation in Hans Kelsen and Max Weber _places the conventional understanding of the theoretical relationship between the work of Kelsen and Weber into question. Focusing on the theoretical foundations of Kelsen’s legal positivism and Weber’s sociology of law, and guided (...) by the conceptual frame of the juridico-political, the contributors to this interdisciplinary volume explore convergences and divergences in the approach and stance of Kelsen and Weber to law, the State, political science, modernity, legal rationality, legal theory, sociology of law, authority, legitimacy and legality. The chapters comprising _The Foundation of the Juridical-Political _uncover complexities within as well as between the theoretical and methodological principles of Kelsen and Weber and, thereby, challenge the enduring division between legal positivism and the sociology of law in contemporary discourse.

What are international codes of conduct for? The broad support for such codes masks fundamental differences about their purpose. Corporations see codes of conduct as regimes for regulating their relations with their suppliers in developing countries and—not least—to counter negative publicity. For labor and human rights activists, on the other hand, codes of conduct are levers for forcing positive change in global labor and environmental standards. Here I consider two areas typically covered by codes of conduct—wages and child labor—and identify (...) some of the dangers of using codes to force change. If low wages or child labor are the result of poverty, and can’t be fixed by enlightened corporate policies, then codes will at best leave the underlying problems untouched and at worst will aggravate them. I conclude that we should be cautious about using codes to force higher standards. (shrink)

Interdisciplinary perspectives on the feature of conscious life that scaffolds every act of cognition: subjective time. Our awareness of time and temporal properties is a constant feature of conscious life. Subjective temporality structures and guides every aspect of behavior and cognition, distinguishing memory, perception, and anticipation. This milestone volume brings together research on temporality from leading scholars in philosophy, psychology, and neuroscience, defining a new field of interdisciplinary research. The book's thirty chapters include selections from classic texts by William James (...) and Edmund Husserl and new essays setting them in historical context; contemporary philosophical accounts of lived time; and current empirical studies of psychological time. These last chapters, the larger part of the book, cover such topics as the basic psychophysics of psychological time, its neural foundations, its interaction with the body, and its distortion in illness and altered states of consciousness.

This paper addresses one aspect of the natural law theory of Germain Grisez. According to Grisez, practical reason identifies the goods of human life prior to the invocation of any moral or normative notions. It can thus provide a non-normative foundation for moral theory. I present Grisez’s position and argue that the apparently non-normative aspect of natural law cannot support the moral position built upon it. I argue, in particular, that practical principles, as Grisez understands them, are best understood as (...) speech acts. If this is correct, it is possible to develop a sceptical challenge to Grisez’s position. (shrink)
