A study of the structural perfection of icosahedral quasicrystalline grains of various alloys and Al-Cu-Fe), grown by different slow solidification techniques was performed using high-resolution diffraction, including recording rocking curves combined with X-ray topography and phase contrast radiography, at a third-generation synchrotron radiation source . For Al-Pd-Mn, additional coherent diffraction and diffuse scattering measurements were also carried out. After evaluating the potentialities of the techniques used, in the light of the criteria defined for crystals, it is shown that the structural (...) perfection of icosahedral quasicrystals is quite comparable with that of metallic crystals but is considerably influenced by either uniform phason strains which can destroy the quasiperiodic long-range order, or by long-wavelength phason fluctuations leading to diffuse scattering. The structural perfection was also found to be extremely variable across the as-grown quasicrystalline grains and to be dependent on the presence and characteristics of inhomogeneities often included in the quasicrystalline matrix. Regarding the grains that we used, it has been impossible to distinguish a clear influence of either the type of alloy or the growth method. It has, however, been noticed that Al-Pd-Mn and Al-Cu-Fe grains appeared less defective than Zn-Mg-RE grains and that the microstructure of these latter grains looks like that of crystals grown by the same technique. Annealing and mechanical polishing effects have also been analysed in the case of Al-Pd-Mn grains. It appeared that annealing improves the quasicrystalline lattice perfection by lowering phason strains insofar as no precipitates are nucleated. Mechanical polishing can introduce defects, located at the external surfaces, having the shape of bands. (shrink)

Yet such a contrast fails to provide an adequate account of the full scope of either philosophy or psychoanalysis. On the one hand, philosophical inquiry is not wholly pre-empted by the question of reality; it may also extend into the realm of phantasy, as can be seen in Plato's effort to determine the epistemological value of eikasia or in Husserl's consideration of Phantasie as a basis of insight into essences. On the other hand, psychoanalysts are as concerned about reality as (...) they are about phantasy. Indeed, one of the key phrases of psychoanalytic therapy is "adaptation to reality." The reason for this concern with reality is clear: if phantasies are modifications or distortions of the real, it is imperative to discern what the character of reality is, especially since it is held out as the standard of a sound state of mental health.

Confidence ratings have often been integrated into reasoning and intelligence tasks as a means for assessing meta-reasoning processes. Although it is often assumed that eliciting these judgements throughout reasoning tasks has no effect on the underlying performance outcomes, this is yet to be established empirically. The current study examines whether eliciting CR from participants during a fluid-reasoning task influences their performance and how this effect is moderated by their initial self-confidence in their own reasoning abilities. In a first experiment, we (...) found that participants performing CR during Raven's Progressive Matrices significantly outperformed a control group who did not provide ratings. Additionally, a second experiment demonstrated that CR only facilitated performance in participants who have a high level of initial self-confidence in their reasoning ability, whereas they were detrimental to participants low in self-confidence.

: Dr. Smith is an internist in private practice who works at an inner city clinic affiliated with a university hospital. He is also a member of the university faculty. Many of Dr. Smith’s patients have type 2 diabetes mellitus and struggle with health care and other costs. Thinking about opportunities to better serve his patients and advance his career, Dr. Smith considers conducting clinical research in his office. ACME is a respected pharmaceutical company that for decades has engaged in (...) research, development, and production of widely used drugs. Several of ACME’s oral agents for type 2 diabetes will soon go off patent. In an effort to retain its market share in this class of drugs, ACME wants to complete clinical trials expeditiously and obtain approval for its new oral hypoglycemic medicine. The company approaches Dr. Smith to be a coinvestigator in its multicenter clinical trial. (shrink)

In classes that examine entrenched injustices like sexism or racism, students sometimes use “distancing strategies” to dissociate themselves from the injustice being studied. Education researchers argue that distancing is a mechanism through which students, especially students of apparent privilege, deny their complicity in systemic injustice. While I am sympathetic to this analysis, I argue that there is much at stake in student distancing that the current literature fails to recognize. On my view, distancing perpetuates socially sanctioned forms of ignorance and (...) unknowing, through which students misrecognize not only their complicity in injustice, but also the ways that injustice shapes the world, their lives, and their knowledge. Thus, distancing is pedagogically problematic because it prevents students from understanding important social facts, and because it prevents them from engaging with perspectives, analyses, and testimonies that might beneficially challenge their settled views and epistemic habits. To substantiate this new analysis, I draw on recent work on epistemologies of ignorance, especially José Medina’s account of “active ignorance.” In order to respond to student distancing, I argue, it is not sufficient for teachers to make students aware of injustice, or of their potential complicity in it. Beyond this, teachers should cultivate epistemic virtue in the classroom and encourage students to take responsibility for better ways of knowing. The article ends by outlining several classroom practices for beginning this work. (shrink)

This paper brings together the work of Nicholas Wolterstorff and William Alston in speech-act theory with the aim of providing a deeper understanding of the nature of divine speaking through the medium of Scripture. Despite the fecundity of Wolterstorff's seminal work on the philosophical theology of Scripture, aspects of his speech-act centric account are underdeveloped and would benefit from the contributions of William Alston. In particular, his account of divine speech-acts could be fruitfully expanded by incorporating the concept of ‘taking (...) responsibility’ that is central to Alston's analysis of the nature of illocutionary acts. This would elucidate both the way in which readers of Scripture encounter divine practical authority in the reading process and the nature of the response of faith that is demanded of them. (shrink)

This volume gathers together for the first time are all the key texts in a crucial debate in modern philosophy, centered on Leibniz's famous 1695 essay, the "New System of the Nature of Substances and their Communication," in which he introduced his strikingly original theory of metaphysics. His "system" became increasingly famous and drew him into discussion and development of these ideas, both in public and in private, with a variety of thinkers, most notably the great French philosopher Pierre Bayle. (...) Woolhouse's and Francks's new English edition gives the only full representation of this debate, and will therefore be essential reading for anyone who wishes to gain a proper understanding of Leibniz's philosophy and its intelletual context. All the texts are newly translated and extensively annotated; many appear in English for the first time. (shrink)

I MAKE NO APOLOGIES for writing about this well-worn topic. For, although there has been an enormous amount written about the account Hume gives of the nature of moral evaluation, commentators are as far from agreement as ever. My own contribution to the controversy has, if anything, not only added to the variety of opinions but also has increased the general confusion. For this I must accept some responsibility. I have certainly laid myself open to some misinterpretation, and the view (...) I have so far expressed in print may also need some modification. I shall here attempt to clarify what precisely my view now is, and why I prefer it to some alternative views advanced by those who find my interpretation of this aspect of Hume's philosophy unacceptable. II. Since what I want to defend is in all important respects my earlier interpretation of the Treatise, 2 I shall for the most part, though not exclusively, be concerned with what Hume says in this, his early, but major, work.

The article interprets Franz Caucig’s Socrates with a Disciple and Diotima?, one of several paintings commissioned for Palais Auersperg in Vienna, now housed at the Slovenian National Gallery. Socrates and a young man are in a pastoral setting beneath a plane tree near a river. They are addressed by a woman, and a chariot with maidens can be seen in the background. The scene is from Plato’s Phaedrus, since Socrates never leaves Athens, except for military service and in this scene (...) from the Phaedrus. The woman addressing Socrates and Phaedrus in the painting cannot be Diotima because her chariot has two white horses, indicating a goddess. The most likely goddess would be the goddess in the poem of Parmenides of Elea, the source of the soul-chariot analogy in the Phaedrus. The setting of Caucig’s Socrates painting bears a remarkable similarity to his Amnytus painting, which features political references to Napoleon’s subjection of Gorizia, Caucig’s homeland. Caucig’s Phaedrus remarks upon Napoleon’s conquests, Hegel’s lectures on Parmenides, and David’s idealized painting of Napoleon crossing the Alps. (shrink)

This essay concerns Scott Shapiro's criticism that H.L.A. Hart's theory of law suffers from a Although other philosophers of law have summarily dismissed Shapiro's criticism, I argue that it identifies an important requirement for an adequate theory of law. Such a theory must explain why legal officials justify their actions by reference to abstract propositional entities, instead of pointing to the existence of social practices. A virtue of Shapiro's planning theory of law is that it can explain this phenomenon. Despite (...) these sympathies, however, I end with the suggestion that Shapiro's criticism of Hart, as it stands, is incomplete. Careful attention to Hart's notion of the internal point of view indicates that he was aware that legal justification ends with abstract objects, not practices, and that he offered his own explanation of this phenomenon.

This article delineates the core concerns and motivations of the ontological work of Gilles Deleuze, and is intended as a programmatic statement for a general philosophical audience. The article consists of two main parts. In the first, two early writings by Deleuze are analysed in order to clarify his understanding of ontology broadly, and to specify the precise aim of his understanding of being in terms of difference. The second part of the article looks at the work of Heidegger and (...) Derrida in order to distinguish Deleuze's conceptions of ontology and difference from theirs. A final section clarifies Deleuze's efforts to undertake the construction of an ontology divergent from the dominant tradition and in contrast to the emphasis on the closure of metaphysics in the thought of Heidegger and Derrida.

Abstract:S. N. Balagangadhara, Sarika Rao, Jakob De Roover, and Marianne Keppens One of the best-known aspects of Indian society is its "rigid caste system" and the "evil practices of untouchability." It is a truism today to say that Indian society is divided into four castes, which are not allowed to mix. Many Indian texts are brought forward as evidence of this understanding of Indian society. The ancient Indian text Mānavadharmaśāstra or "Laws of Manu" takes a central place in such accounts. (...) This is especially the case for its verses on varṇasankara, translated as "mixing of social classes" or "intermixture of castes." Given the important role these verses play in the understanding of Indian culture, society, and policymaking, it is crucial to translate them accurately. Using one verse in one text, this article focuses on the standard translation and deals both critically and constructively with the received view. (shrink)

In his case report, A Logic in Madness, Aaron Hauptman details the case of Mr. A, an intelligent college student with Asperger’s syndrome, who became severely depressed subsequent to what he perceived as a rejection by what he viewed as “the love of his life.” Dr. Hauptman describes Mr. A as suicidal and as suffering from all the hallmarks of a major depression. At the urging of his family, he presents himself to a psychiatric inpatient unit and agrees to a (...) voluntary hospitalization. However, he refuses pharmacological treatment or electroconvulsive therapy, both of which his clinicians are considering given the severity of his case. Dr. Hauptman describes the young man’s response... (shrink)

Volume 8 of this landmark edition follows Peirce from May 1890 through July 1892—a period of turmoil as his career unraveled at the U.S. Coast and Geodetic Survey. The loss of his principal source of income meant the beginning of permanent penury and a lifelong struggle to find gainful employment. His key achievement during these years is his celebrated Monist metaphysical project, which consists of five classic articles on evolutionary cosmology. Also included are reviews and essays from The Nation in (...) which Peirce critiques Paul Carus, William James, Auguste Comte, Cesare Lombroso, and Karl Pearson, and takes part in a famous dispute between Francis E. Abbot and Josiah Royce. Peirce's short philosophical essays, studies in non-Euclidean geometry and number theory, and his only known experiment in prose fiction complete his production during these years. Peirce's 1883-1909 contributions to the Century Dictionary form the content of volume 7 which is forthcoming. (shrink)
