Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This is the sequel to the previously reviewed first volume of a proposed three volume study of Proust as philosopher. Good as the first volume is, this is even better. It is extremely difficult, unusually subtle, and demands slow and ruminative reading. For the present reviewer, the book falls naturally into two parts, each with its own peak or crescendo. The key to understanding the book is to hear the two crescendos in unison, or better, in harmony. The first crescendo (...) begins at about page 97 and culminates on page 112. A crucial passage: "Le point de création: le point instable et indécis, où la vague se lève, où le dessin, la plume en feront un duvet.... Tout est allégorie et possibilité de métaphore ou de métamorphose: les choses ne sont pas, elles ne savent pas; elles sont quelquefois l'attente, l'impatience. Il faut venir à point et dans le bon moment." And another: "C'est parce que rien n'est marqué dans une complexion définitive, imprimée dans l'espace, que l'art peut approcher, regarder, rectifier. Non pas décrire et reproduire: réinventer". The second crescendo begins with a distinction between voluntary and involuntary memory, with a long culminating passage extending from page 238 to page 265. This may be summarized as follows: I do not produce but await my memories, which come as if from another and construct what I am. Now to combine the two crescendos: I make the world, and the world makes me. The second crescendo is already anticipated in the first, e.g., p. 97: art does not invent but articulates and structures nature. The first crescendo is resumed or echoed in the second : the work of art is the most perfect form of reality. To give another formulation to the harmony of the two crescendos: in order to perceive, one must remember; yet one cannot remember unless one has perceived. Hence perception and memory remake each other. In sum, I am that spectator of the world who makes, and is made by, the world. We cannot really perceive things except via an image of them which we produce and which provides us, not with an objective representation of the perceived things, but with an equilibrium between our desires and emotions on the one hand, and the perceptions on the other. This produced image is presumably the aforementioned perception of a memory. And thus we respond to the uniqueness of our perceptions, via our produced images, by uniting them into a world, each of which is again unique, and yet, which is in each case the same single world in which we all dwell. On this reading, Proust's theme is the equilibrium between seeing and producing, or between theory and practice at the level of the constitution of the world. To oversimplify drastically, Proust teaches the Platonic demiurge but not the Platonic Ideas. As a consequence, one is intermittently reminded of a quasi-Husserlian phenomenology rooted in the primacy of intentionality as enacted in perception. But the mathematicism of Husserl is absent; the intentionality is that of a poet.-Stanley Rosen, Pennsylvania State University. (shrink)

Quantum theory predicts that, e.g., in a Stern-Gerlach experiment with electrons the measured spin component $S_Z = \pm \frac{1}{2}$ does not come about by an adjustment at the last moment, a forced “flipping” or “tilting” of the spin (vector), which would imply z-angular momentum exchange between particle and instrument, but will afterward appear to have had the value $\frac{1}{2} or - \frac{1}{2}$ already before the measurement. Because an electron spin cannot have components $ \pm \frac{1}{2}$ in all directions at the (...) same time, the measuring direction has a “privileged” status before the measurement, however we choose that direction, which implies a retroactive effect. A second proof of retroactivity is derived from a special case of the paradox of Einstein, Podolsky, and Rosen. It is strongly suggested by our result that, in essential respects, both Bohr and Einstein were right in their famous controversy about determinism and considering microprocesses “as a whole.”.

The Shadow of God combines history and philosophy in a way that is, unlike Hegel, fundamentally pluralistic. It presents the period of German Idealism as a time when philosophers aimed to bring faith and reason together through the idea of autonomy. At the same time, the tensions endemic in that process led to a transfer of individual hope from an afterlife of reward or punishment to participation in a collective, historical process. This article responds to a series of critical questions: (...) Does the book assimilate consolation and reconciliation? Does it sufficiently distinguish knowledge and justification? Does it open the possibility for a reaffirmation of the individual? Does it underestimate the potential for a secularized Kantian philosophy to bring together equality, justification, and community? Does its interpretation of Kant give a place for his account of historical progress? Is awareness of the way in which theodicy came to be historicized helpful in understanding contemporary democracy and its discontents? (shrink)

Since weakly decaying particles are their own polarimeters, reactions like $\eta _c \to \Lambda \bar \Lambda , \psi \to \Lambda \bar \Lambda ,e^ + e^ - \to \mu ^ + \mu ^ -$ , etc. are interesting for testing the non-locality of quantum mechanical predictions. Although such reactions, in principle, do not exclude all classes of hidden variable theories, they can be used to complement current experiments with external polarimeters. The reaction $\eta _c \to \Lambda \bar \Lambda \to \pi ^ (...) - p\pi ^{ + - } \bar p$ is conceptually the simplest and most useful as agedanken experiment, although it has not yet been seen experimentally. The reaction $e^ + e^ - \to \Lambda \bar \Lambda \to \pi ^ - p\pi ^ + \bar p$ near threshold or at the φ resonance can be used for essentially the same test. This is feasible with presently available data and would be the first EPR experiment involving weak interactions. (shrink)

A new realislic local model of light propagation and detection is described. The authors propose a novel stochastic model of low-intensity photon detection in which background noise is added to a part of the photon prior to absorption. In this model, in agreement with Planck, there is no quantization of the propagating field. The model has some similarities to theories advanced by E. Santos and T. Marshall in the last decade, but also has substantial deviations from these. A mechanism, conserving (...) energy and momentum, is proposed by which a sudden collapse of the wave-packet is avoided. The experimental Bell inequality violation of Aspect. Grangier and Roger [Phys. Rev. Lett.47, 460 (1981)]is discussed. The authors have carried out a computer simulation of a radio frequency (RF) analogue of the Einstein-Podolsky-Rosen thought experiment to illustrate how the manipulation of certain factors, especially signal to noise ratio, detector threshold and characteristics of the noise, enables the same Bell inequality to be either satisfied or violated by a realistic local model. Building on arguments by Santos. [Phys. Rev. A46. 3646 (1992)],the appropriateness of this Bell lest is discussed. Neither the authors' stochastic-optical model, nor their RF analogue, involves an enhancement assumption of the type defined by Clauser and Horne [Phys. Rev. D10, 526 (1974)]. (shrink)

Public policy issues around access to networked information are explored and examined. Long viewed as the quintessential public good, information has evolved into a critically important market commodity in little more than a generation. New technologies and a political climate in which the meaning of universal access to information is no longer commonly understood and in which its importance is no longer taken for granted pose significant challenges for American society. Libraries, as information commons, offer the means of meeting those (...) challenges. Historical, economical, and professional factors that shape the conflict are described and discussed. (shrink)

The last decade has seen an explosion of research on the gut microbiota—the trillions of microorganisms that colonize the human gut. It is now clear that interindividual diversity in microbiota composition plays an important role in determining susceptibility to a wide variety of diseases. However, identifying the precise changes in microbiota composition that play causal roles has remained a largely unrealized goal. Here, we propose that functional classifications of microbes based on their interactions with and effects on the host—particularly the (...) host immune system—will illuminate the role of the microbiota in shaping human physiology. We outline the benefits of “functional” classification compared to phylogenetic classifications, and review current efforts at functional classification of the microbiota. Finally, we outline a theoretical framework for classifying host-microbiota interactions. Future advances enabling broader functional classifications of the microbiota promise to revolutionize our understanding of the role of gut microbes in health and disease. Functional classifications of the human microbiota reveal previously hidden patterns and will be key to cracking the microbiota composition code. This figure shows a theoretical comparison between phylogenetic classification and functional classification of a host-associated microbial community. (shrink)

Region R Question: How many objects — entities, things — are contained in R? Ignore the empty space. Our question might better be put, 'How many material objects does R contain?' Let's stipulate that A, B and C are metaphysical atoms: absolutely simple entities with no parts whatsoever besides themselves. So you don't have to worry about counting a particle's top half and bottom half as different objects. Perhaps they are 'point-particles', with no length, width or breadth. Perhaps they are (...) extended in space without possessing spatial parts (if that is possible). Never mind. We stipulate that A, B and C are perfectly simple. We also stipulate that they are connected as follows. A and B are stuck together in such a way that when a force is applied to one of them, they move together 'as a unit'. Moreover, the two of them together exhibit behavior that neither would exhibit on its own — Perhaps they emit a certain sound, or glow in the dark — whereas C is.. (shrink)

Generalizing the work of Einstein and Mayer, it is assumed that at each point of space-time there exists an N-dimensional linear vector space with N≥5. This space is decomposed into a four-dimensional tangent space and an (N - 4)-dimensional internal space. On the basis of geometric considerations, one arrives at a number of fields, the field equations being derived from a variational principle. Among the fields obtained there are the electromagnetic field, Yang-Mills gauge fields, and fields that can be interpreted (...) as describing matter. As a simple example, the case N=6 is considered.

Cognitive neuroscience has inspired a number of methodological advances to extract the highest signal-to-noise ratio from neuroimaging data. Popular techniques used to summarize behavioral data include sum-scores and item response theory. While these techniques can be useful when applied appropriately, item dimensionality and the quality of information are often left unexplored allowing poor performing items to be included in an itemset. The purpose of this study is to highlight how the application of two-stage approaches introduces parameter bias, differential item functioning (...) can manifest in cognitive neuroscience data and how techniques such as the multiple indicator multiple cause model can identify and remove items with DIF and model these data with greater sensitivity for brain–behavior relationships. This was performed using a simulation and an empirical study. The simulation explores parameter bias across two separate techniques used to summarize behavioral data: sum-scores and IRT and formative relationships with those estimated from a MIMIC model. In an empirical study participants performed an emotional identification task while concurrent electroencephalogram data were acquired across 384 trials. Participants were asked to identify the emotion presented by a static face of a child across four categories: happy, neutral, discomfort, and distress. The primary outcomes of interest were P200 event-related potential amplitude and latency within each emotion category. Instances of DIF related to correct emotion identification were explored with respect to an individual’s neurophysiology; specifically an item’s difficulty and discrimination were explored with respect to an individual’s average P200 amplitude and latency using a MIMIC model. The MIMIC model’s sensitivity was then compared to popular two-stage approaches for cognitive performance summary scores, including sum-scores and an IRT model framework and then regressing these onto the ERP characteristics. Here sensitivity refers to the magnitude and significance of coefficients relating the brain to these behavioral outcomes. The first set of analyses displayed instances of DIF within all four emotions which were then removed from all further models. The next set of analyses compared the two-stage approaches with the MIMIC model. Only the MIMIC model identified any significant brain–behavior relationships. Taken together, these results indicate that item performance can be gleaned from subject-specific biomarkers, and that techniques such as the MIMIC model may be useful tools to derive complex item-level brain–behavior relationships.

Generalizing the work of Einstein and Mayer, it is assumed that at each point of space-time there exists a vector-spinor space with Nv vector dimensions and Ns spinor dimensions, where Nv=2k and Ns=2 k, k⩾3. This space is decomposed into a tangent space with4 vector and4 spinor dimensions and an internal space with Nv−4 vector and Ns−4 spinor dimension. A variational principle leads to field equations for geometric quantities which can be identified with physical fields such as the electromagnetic field, (...) Yang-Mills gauge fields, and wave functions of bosons and fermions. (shrink)

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings. Although formulated as a study in the logic of norms, it provided the initial ideas for work on the logic of theory (or belief) change, developed by the authors in a series of papers by the authors and Peter Gardenfors beginning in 1985.

De uma perspectiva comportamentalista radical, o eu é um repertório verbal complexo, que, como tal, tem uma gênese social. O reconhecimento da origem social do “eu” abre caminho para uma análise política, incluindo uma discussão do pa- pel das relações de poder na constituição do eu. Entretanto, uma concepção radicalmente social do “eu”, como a proposta pelo comportamentalismo, suscita um problema político: se o eu é integralmente produto do ambiente social, de onde viria uma eventual “vontade” de romper com esse (...) sistema? Parece que para reconhecer a possibilidade de ação política transformadora seria preciso preservar uma noção descontextualizada de “eu”. Considerando essa dificuldade, o objetivo deste artigo é propor uma interpretação política da constituição do “eu” no âmbito do comportamentalismo radical, mantendo no horizonte a possibilidade de uma ação política transformadora. Para tanto, destacamos como “eus” oprimidos são tornados submissos, mas também como de certas contingências podem emergir “eus” subversivos, que se opõem a um sistema social opressivo. Esse “eu” subversivo é caracterizado por um repertório de autoconhecimento mais amplo, que inclui a discriminação do papel das relações de poder e do controle promovido por instituições. Concluímos, com isso, que um “eu” socialmente constituído pode ser politicamente ativo. (shrink)

According to one sort of epistemic relativist, normative epistemic claims (e.g., evidence E justifies hypothesis H) are never true or false simpliciter, but only relative to one or another epistemic system. In chapter 6 of Fear of Knowledge, Paul Boghossian objects to this view on the ground that its central notions cannot be explained, and that it cannot account for the normativity of epistemic discourse. This paper explores how the dogged relativist might respond.

Because spaying/neutering animals involves the harming of some animals in order to prevent harm to others, some ethicists, like David Boonin, argue that the philosophy of animal rights is committed to the view that spaying/neutering animals violates the respect principle and that Trap Neuter Release programs are thus impermissible. In response, I demonstrate that the philosophy of animal rights holds that, under certain conditions, it is justified, and sometimes even obligatory, to cause harm to some animals in order to prevent (...) greater harm to others. As I will argue, causing lesser harm to some animals in order to prevent greater harm to others, as TNR programs do, is compatible with the recognition of the inherent value of the ones who are harmed. Indeed, we can, and do, spay/neuter cats while acknowledging that they have value in their own right. (shrink)

During the past decade there has been a very effective campaign against any explanation of remembering whose basic concept is that of a causally mediating trace. This paper attempts to provide such an explanation by presenting an explicit deductive argument for the existence of the memory trace. The conclusion is shown to follow from reasonable, empirical assumptions of which the most interesting is a spatiotemporal contiguity thesis. Set-theoretic techniques are used to provide a framework of analysis and probabilistic definitions of (...) some causal notions, as that of a causal chain, are presented. (shrink)

"The writer discusses the concept of kitsch. Having reviewed a variety of approaches to kitsch, he posits an historical conception of it, connecting it to modernity and defining it as a coping-mechanism for modernity. He thus suggests that kitsch is best understood as a tool in the struggle against the particular stresses of the modern world and that it uses materials at hand, fashioning from them some sort of stability largely through projecting images of nature, stasis, and continuity. He discusses (...) the relation of kitsch to fine art, arguing that fine art also has as its primary function a counter-movement to modernity. He suggests that the main difference between fine art and kitsch is that fine art, as well as its emotional function, also involves a reception context that allows it to assume an intellectual task. Among the writer's conclusions, he finds that positing a stark or absolute contrast between kitsch and fine art is unjustifiable as both have the same roots and objectives." [WilsonWeb]. (shrink)

An adequate theory of rights ought to forbid the harming of animals to promote trivial interests of humans, as is often done in the animal-user industries. But what should the rights view say about situations in which harming some animals is necessary to prevent intolerable injustices to other animals? I develop an account of respectful treatment on which, under certain conditions, it’s justified to intentionally harm some individuals to prevent serious harm to others. This can be compatible with recognizing the (...) inherent value of the ones who are harmed. My theory has important implications for contemporary moral issues in nonhuman animal ethics, such as the development of cultured meat and animal research. (shrink)

"C.E. Emmer’s article addresses the ongoing debates over how to classify and understand kitsch, from the inception of postmodern culture onwards. It is suggested that the lack of clear distinction between fine art and popular culture generates 'approaches to kitsch – what we might call 'deflationary' approaches – that conspire to create the impression that, ultimately, either 'kitsch' should be abandoned as a concept altogether, or we should simply abandon ourselves to enjoying kitschy objects as kitsch.' The author offers critical (...) insight into 'kitschy' items made in response to 9/11 and tries to examine the reception of these products through scrutinizing a selection of remarks posted by the Internet commentators."

This chapter is written for an audience that is not intimately familiar with the philosophy of animal consumption. It provides an overview of the harms that animals, the environment, and humans endure as a result of industrial animal agriculture, and it concludes with a defense of ostroveganism and a tentative defense of cultured meat.

In The Case for Animal Rights, Tom Regan argues that although all subjects-of-a-life have equal inherent value, there are often differences in the value of lives. According to Regan, lives that have the highest value are lives which have more possible sources of satisfaction. Regan claims that the highest source of satisfaction, which is available to only rational beings, is the satisfaction associated with thinking impartially about moral choices. Since rational beings can bring impartial reasons to bear on decision making, (...) Regan maintains that they have an additional possible source of satisfaction that nonrational beings do not have and, consequently, the lives of rational beings turn out to have greater value..

This paper brings to light the significance of Merleau-Ponty’s thinking for contemporary physics. The point of departure is his 1956–57 Collège de France lectures on Nature, coupled with his reflections on the crisis in modern physics appearing in THE VISIBLE AND THE INVISIBLE. Developments in theoretical physics after his death are then explored and a deepening of the crisis is disclosed. The upshot is that physics’ intractable problems of uncertainty and subject-object interaction can only be addressed by shifting its philosophical (...) base from objectivism to phenomenology, as Merleau-Ponty suggested. Merleau-Ponty’s allusion to “topological space” in THE VISIBLE AND THE INVISIBLE provides a clue for bridging the gap between “hard science” and “soft philosophy.” This lead is pursued in the present paper by employing the paradoxical topology of the Klein bottle. The hope is that, by “softening” physics and “hardening” phenomenology, the “two cultures” (cf. C. P. Snow) can be wed and a new kind of science be born. (shrink)

A widely accepted view in epistemology is that we do not have direct control over our beliefs. And we surely do not have as much control over our beliefs as we have over simple actions. For instance, you can, if offered $500, immediately throw your steak in the trash, but a meat-eater cannot, at will, start believing that eating animals is wrong to secure a $500 reward. Yet, even though we have more control over our behavior than we have over (...) our beliefs, some of our behavior, especially moral behavior, is heavily influenced by our beliefs. Meat-eating is one example. So, if we do not have direct control over our beliefs and our beliefs influence our moral behavior, it’s no wonder meat-eaters aren’t immediately boycotting Burger King and lining up for the Beyond Burger after hearing about the mistreatment of farmed animals. So, how, or can we, inspire meat-eaters to change their beliefs regarding the moral significance of meat-eating and, consequently, their animal-eating behavior? I propose an answer to this difficult question. (shrink)

The distinction between clinical practice and surgical research may seem trivial, but this distinction can become a complex issue when innovative surgeries are substituted for standard care without patient knowledge. Neither the novelty nor the risk of a new surgical procedure adequately defines surgical research. Some institutions tacitly allow the use of new surgical procedures in series of patients without informing individuals that they are participating in a scientific study, as long as no written protocol or hypothesis exists. Institutions can (...) justify this practice by viewing human research in narrow terms as an activity outlined in a formal protocol. Application of limited definitions, however, erodes patients' rights and risks losing public confidence in how biomedical research is conducted. I propose an operational definition of human research also be recognised. Enforcing more rigid and less ambiguous guidelines of human research may curtail enrolment into some studies, but it will also protect patients from being used as subjects without their knowledge.
