The Fort Worth basin is one of the most fully developed shale gas fields in North America. Although there are hundreds of drilled wells in the basin, almost none of them reach the Precambrian basement. Imaged by perhaps 100 3D seismic surveys, the focus on the relatively shallow, flat-lying Barnett Shale objective has resulted in little published work on the basement structures underlying the Lower Paleozoic strata. Subtle folds and systems of large joints are present in almost all 3D seismic (...) surveys in the FWB. At the Cambro-Ordovician Ellenburger level, these joints are often diagenetically altered and exhibit collapse features at their intersections. We discovered how the basement structures relate to overlying Paleozoic reservoirs in the Barnett Shale and Ellenburger Group. In support of our investigation, the Marathon Oil Company provided a high-quality, wide-azimuth, 3D seismic data near the southeast fringe of the FWB. In addition to the seismic volume, we integrated the seismic results with gravity, magnetic, well log, and geospatial data to understand the basement and subbasement structures in the southeast FWB. Major tectonic features including the Ouachita frontal thrust belt, Lampasas arch, Llano uplift, and Bend arch surround the southeast FWB. Euler deconvolution and integrated forward gravity modeling helped us extend our interpretation beyond the 3D seismic survey into a regional context. (shrink)

I. Introduction Two kinds of remedies have traditionally been employed for breach of contract: legal relief and equitable relief. Legal relief normally takes the form of money damages. Equitable relief normally consists either of specific performance or an injunction – that is, the party in breach may be ordered to perform an act or to refrain from performing an act. In this article I will use a “consent theory of contract” to assess the choice between money damages and specific performance. (...) According to such a theory, contractual obligation is dependent on more fundamental entitlements of the parties and arises as a result of the parties' consent to transfer alienable rights. My thesis will be that the normal rule favoring money damages should be replaced with one that presumptively favors specific performance unless the parties have consented to money damages instead. The principal obstacle to such an approach is the reluctance of courts to specifically enforce contracts for personal services. The philosophical distinction between alienable and inalienable rights bolsters this historical reticence, since a right to personal services may be seen as inalienable. I will then explain why, if the subject matter of a contract for personal services is properly confined to an alienable right to money damages for failure to perform, specific enforcement of such contracts is no longer problematic. Finally, I shall consider whether the subject matter of contracts for corporate services is properly confined to money damages like contracts for personal services, or whether performance of corporate services can be made the subject of a valid rights transfer and judicially compelled in the same manner as contracts for external resources.

Dead reckoning is a feature of the navigation behaviour shown by several creatures, including the desert ant. Recent work by C. Randy Gallistel shows that some connectionist models of dead reckoning face important challenges. These challenges are thought to arise from essential features of the connectionist approach, and have therefore been taken to show that connectionist models are unable to explain even the most primitive of psychological phenomena. I show that Gallistel’s challenges are successfully met by one recent connectionist (...) model, proposed by Ulysses Bernardet, Sergi Bermúdez i Badia, and Paul F.M.J. Verschure. The success of this model suggests that there are ways to implement dead reckoning with neural circuits that fall within the bounds of what many people regard as neurobiologically plausible, and so that the wholesale dismissal of the connectionist modelling project remains premature.

This book is designed to remedy that lack.

It is hypothesized that human faces judged to be attractive by people possess two features—averageness and symmetry—that promoted adaptive mate selection in human evolutionary history by way of production of offspring with parasite resistance. Facial composites made by combining individual faces are judged to be attractive, and more attractive than the majority of individual faces. The composites possess both symmetry and averageness of features. Facial averageness may reflect high individual protein heterozygosity and thus an array of proteins to which parasites (...) must adapt. Heterozygosity may be an important defense of long-lived hosts against parasites when it occurs in portions of the genome that do not code for the essential features of complex adaptations. In this case heterozygosity can create a hostile microenvironment for parasites without disrupting adaptation. Facial bilateral symmetry is hypothesized to affect positive beauty judgments because symmetry is a certification of overall phenotypic quality and developmental health, which may be importantly influenced by parasites. Certain secondary sexual traits are influenced by testosterone, a hormone that reduces immunocompetence. Symmetry and size of the secondary sexual traits of the face (e.g., cheek bones) are expected to correlate positively and advertise immunocompetence honestly and therefore to affect positive beauty judgments. Facial attractiveness is predicted to correlate with attractive, nonfacial secondary sexual traits; other predictions from the view that parasite-driven selection led to the evolution of psychological adaptations of human beauty perception are discussed. The view that human physical attractiveness and judgments about human physical attractiveness evolved in the context of parasite-driven selection leads to the hypothesis that both adults and children have a species-typical adaptation to the problem of identifying and favoring healthy individuals and avoiding parasite-susceptible individuals. It is proposed that this adaptation guides human decisions about nepotism and reciprocity in relation to physical attractiveness. (shrink)

The study begins with the language employed in and the psychological basis of thought experiments as understood by certain medieval Arabic philosophers. It then provides a taxonomy of different kinds of thoughts experiments used in the medieval Islamic world. These include purely fictional thought experiments, idealizations and finally thought experiments using ingenious machines. The study concludes by suggesting that thought experiments provided a halfway house during this period between a staunch rationalism and an emerging empiricism.

: The present study considers Ibn Sînâ's (Lat. Avicenna) account of induction (istiqra') and experimentation (tajriba). For Ibn Sînâ induction purportedly provided the absolute, necessary and certain first principles of a science. Ibn Sînâ criticized induction, arguing that it can neither guarantee the necessity nor provide the primitiveness required of first principles. In it place, Ibn Sînâ developed a theory of experimentation, which avoids the pitfalls of induction by not providing absolute, but conditional, necessary and certain first principles. The theory (...) of experimentation that emerges though not modern, does have elements that are similar to a modern conception of scientific method. (shrink)

The growing body of whistleblowing literature includes many studies that have attempted to identify the individual level antecedents of whistleblowing behavior. However, cross-cultural differences in perceptions of the ethicality of whistleblowing affect the judgment of whistleblowing intention. This study ascertains how Chinese managers/professionals decide to blow the whistle in terms of their locus of control and subjective judgment regarding the intention of whistleblowing. Hypotheses that are derived from these speculations are tested with data on Chinese managers and professionals. Statistical analysis (...) largely supports the hypotheses, which suggests that an individual''s locus of control does moderate the relationship between ethical judgment and whistleblowing. (shrink)

Paraconsistent logics are characterized by rejection of ex falso quodlibet, the principle of explosion, which states that from a contradiction, anything can be derived. Strikingly these logics have found a wide range of application, despite the misgivings of philosophers as prominent as Lewis and Putnam. Such applications, I will argue, are of significant philosophical interest. They suggest ways to employ these logics in philosophical and scientific theories. To this end I will sketch out a ‘naturalized semantic dialetheism’ following Priest’s early (...) suggestion that the principles governing human natural language may well be inconsistent. There will be a significant deviation from Priest’s work, namely, the assumption of a broadly Chomskyan picture of semantics. This allows us to explain natural language inconsistency tolerance without commitment to contentious views in formal logic. (shrink)

The paper treats Avicenna’s ’metaphysical’ argument for the existence of God and the modal metaphysics that underpins it. Earlier analyses of modalities attempted to reduce necessity, possibility and impossibility to nonmodal elements, which was done most commonly by appealing to a temporal frequency model of modalities. In contrast, Avicenna believed that modalities were an inherent feature of existence, and so just as there is nothing more basic than existence, so likewise there is nothing more basic in term of which modalities (...) can be explained. The article concludes by considering how Avicenna’s modal metaphysics in turn provides him the means to show the absolute and nonconditional necessity of God, as opposed to the conditional necessity of earlier ’physical’ arguments.

Aristotle's account of place in terms of an innermost limit of a containing body was to generate serious discussion and controvery among Aristotle's later commentators, especially when it was applied to the cosmos as a whole. The problem was that since there is nothing outside of the cosmos that could contain it, the cosmos apparently could not have a place according to Aristotle's definition; however, if the cosmos does not have a place, then it is not clear that it could (...) move, but it was thought to move, namely, in its daily revolution, which was viewed as a kind of natural locomotion and so required the cosmos to have a place. The study briefly outlines Aristotle's account of place and then considers its fate, particularly with respect to the cosmos and its motion, at the hands of later commentators. To this end, it begins with Theophrastus' puzzles concerning Aristotle's account of place, and how later Greek commentators, such as Alexander of Aphrodisias, Themistius and others, attempted to address these problems in what can only be described as ad hoc ways. It then considers Philoponus' exploitation of these problems as a means to replace Aristotle's account of place with his own account of place understood in terms of extension. The study concludes with the Arabic Neoplatonizing Aristotelian Avicenna and his novel introduction of a new category of motion, namely, motion in the category of position. Briefly, Avicenna denies that the cosmos has a place, and so claims that it moves not with respect to place, but with respect to position. (shrink)

This volume introduces the major classical Arabic philosophers through substantial selections from the key works (many of which appear in translation for the first time here) in each of the fields—including logic, philosophy of science, natural philosophy, metaphysics, ethics, and politics—to which they made significant contributions. -/- An extensive Introduction situating the works within their historical, cultural, and philosophical contexts offers support to students approaching the subject for the first time, as well as to instructors with little or no formal (...) training in Arabic thought. A glossary, select bibliography, and index are also included. (shrink)

A caged animal in the heart of the city, thousands of miles from its natural habitat, neurotically pacing in its confinement . . . Zoos offer a convenient way to indulge a cultural appetite for novelty and diversion, and to teach us, albeit superficially, about animals. Yet what, conversely, do they tell us about the people who create, maintain, and patronize them, and about animal captivity in general? Rather than foster an appreciation for the lives and attributes of animals, zoos, (...) in Randy Malamud's view, reinforce the idea that we are, by nature, an imperial species: that our power and ingenuity entitles us to violate the natural order by tearing animals from the fabric of their ecosystems and displaying them in an "order" of our own making. In so doing, he argues, zoos not only contribute to the rapid disintegration of our ecosystems, but also deaden our very sensibilities to constraint, spatial disruption, and physical pain. Invoking an array of literary depictions of animals, from Albee's Zoo Story and Virginia Woolf's diaries to the films of Harold Pinter and the poetry of Marianne Moore, Reading Zoos links culture, literature, and nature in an engaging and accessible introduction to environmental ethics, animal rights, cultural critique, and literary representation.

A debated topic in Avicennan psychology is whether for Avicenna abstraction is a metaphor for emanation or to be taken literally. This issue stems from the deeper philosophical question of whether humans acquire intelligibles externally from an emanation by the Active Intellect, which is a separate substance, or internally from an inherently human cognitive process, which prepares us for an emanation from the Active Intellect. I argue that the tension between thesedoctrines is only apparent. In his logical works Avicenna limns (...) an account where through the internal human process of abstraction accidents accruing to an essence existing in matter are extracted, thus preparing the essence for new accidents emanating externally from the Active Intellect, which make the essence something conceptualized in the intellect. This study, then, outlines the epistemological and metaphysical framework presented in the logical works that underpins Avicenna’s theory of abstraction presented in his psychological works.

Pierre Klossowski's career in philosophy is a brief but significant intervention into the manner in which the connections between desire, identity, and meaning are thought. Although Klossowski's influence on much of what is called French “post-structuralism” or “post-modernism” is frequently noted, Klossowski's development of the motif of the simulacrum is rarely traced in its proper context. Through readings of the texts of the Marquis de Sade, Georges Bataille, and Friedrich Nietzsche, as well as his own ruminations on the polytheism of (...) the ancient Roman cult of Diana, Klossowski constructs a critique not only of the identity of the self but also of the supposed unity of reason and rational signs. Klossowski's critique demonstrates how meaningful discourse is produced from the basis of incommunicable affects, which project images in consciousness that, only then, are able to take the form of iterable simulacra. Our “gregarious” discourse in language is, thus, formed only indirectly from the affects and acquires its supposed unity only as it fails to express those affects. (shrink)

The forma fluens/fluxus formae debate concerns the question as to whether motion is something distinct from the body in motion, the flow of a distinct form identified with motion , or nothing more than the successive states of the body in motion, the flow of some form found in one of Aristotle's ten categories . Although Albertus Magnus introduced this debate to the Latin West he drew his inspiration from Avicenna. This study argues that Albertus misclassified Avicenna's position, since Albertus (...) could not conceptualize motion at an instant, whereas it is claimed here this was the very position Avicenna adopted. The paper includes an overview of Albertus's discussion and a brief survey of the Avicennan sources upon which Albertus drew. The heart of the paper treats Avicenna's analysis of motion at an instant. Avicenna's general argument was that since spatial points have no extremities, nothing in principle prevents a moving object from being at a spatial point for more than an instant, understood as a limit. It is then argued that Avicenna had the philosophical machinery to make sense of a limit, albeit not in mathematical terms, but in terms of an Aristotelian potential infinite. (shrink)
