Christopher Hom has recently argued that the best-overall account of the meaning of pejorative terms is a semantic account according to which pejoratives make a distinctive truth-conditional contribution, and in particular express complex, negative socially constructed properties. In addition, Hom supplements the semantic account with a pragmatic strategy to deal with the derogatory content of occurrences of pejorative terms in negations, conditionals, attitude reports, and so on, according to which those occurrences give rise to conversational implicatures to the effect that (...) the pejorative terms are non-empty, which explains the offensiveness of those occurrences. In this paper, I aim to defend this semantic strategy from several recent objections, and I will also present a novel objection, which in my view shows that we should understand the semantic account as a version of inferentialism, rather than radical externalism.

If mathematics is regarded as a science, then the philosophy of mathematics can be regarded as a branch of the philosophy of science, next to disciplines such as the philosophy of physics and the philosophy of biology. However, because of its subject matter, the philosophy of mathematics occupies a special place in the philosophy of science. Whereas the natural sciences investigate entities that are located in space and time, it is not at all obvious that this is also the case (...) with respect to the objects that are studied in mathematics. In addition to that, the methods of investigation of mathematics differ markedly from the methods of investigation in the natural sciences. Whereas the latter acquire general knowledge using inductive methods, mathematical knowledge appears to be acquired in a different way, namely, by deduction from basic principles. The status of mathematical knowledge also appears to differ from the status of knowledge in the natural sciences. The theories of the natural sciences appear to be less certain and more open to revision than mathematical theories. For these reasons mathematics poses problems of a quite distinctive kind for philosophy. Therefore philosophers have accorded special attention to ontological and epistemological questions concerning mathematics. (shrink)

Den Philosophen und Theologen Friedrich Schleiermacher und den dänischen Philosophen, Mineralogen und Theologen Henrik Steffens verband nicht nur eine enge Freundschaft, sondern sie verstanden sich – kurz nacheinander 1804 an die Universität Halle berufen – auch als wissenschaftliches Pendant. Grundlegend für den gefühlten Gleichklang beider Köpfe ist der romantische Gedanke progressiver Universalität, der auf der Suche nach einer angemessenen wissenschaftlichen Methodik gleichermaßen die Forderung nach System und Antisystem, System und seine Subversion generiert. Trotz dieser häufig konstatierten wissenschaftlichen Entsprechung beider Denker (...) ist ihr systematisches Verhältnis bis dato in der Forschung kaum bedacht und ebenso Desiderat wie die philosophische Literatur zu Steffens Werk überhaupt. Die Beiträge des Bandes gehen biographischen Spuren nach, thematisieren die Einheit des Wissens im Spannungsverhältnis von System und Subversion, untersuchen das Wechselverhältnis von Ethik und Physik, Naturphilosophie und Naturwissenschaft und fragen auch nach den im Verlauf ihrer Freundschaft zunehmenden Differenzen im Denken beider Philosophen, die sich nicht zuletzt in ihren theologischen und kirchenpolitischen Schriften manifestieren.

Para explorar las diferencias significativas entre estos dos pensadores, la primera parte de este articulo considerará sus ideas ontológicas. Comenzando con su preocupación común por la multiplicidad, exploraremos el movimiento fundacional de Deleuze hacia diferentes tipos de multiplicidad. La crítica de Badiou a este enfoque estará relacionada con su defensa de los recursos abstractos de la teoría de conjuntos en oposición a las síntesis concretas con las que Deleuze busca comenzar. La segunda parte de este documento explorará las consecuencias de (...) los compromisos ontológicos de Deleuze cuando se trata de la ética del acontecimiento exigido por Badiou. El compromiso de Deleuze con el estoicismo proporcionará el escenario para su explicación de cómo ocurren los acontecimientos y representa una fuente de pensamiento y actividad. En la tercera y última parte se buscará evaluar la explicación de Deleuze sobre el papel de los acontecimientos en situaciones particulares y en las actividades de los sujetos que responden a estos. Esto nos permitirá sacar conclusiones sobre la crítica de Badiou a Deleuze y la capacidad de Deleuze para resistir estas críticas. Argumentaré que Deleuze comparte con Badiou la preocupación de mantener una visión clara del tema como una figura comprometida en la búsqueda de proyectos nuevos e inauditos que responden al llamado de los acontecimientos.

Given any finite graph, which transitive graphs approximate it most closely and how fast can we find them? The answer to this question depends on the concept of “closest approximation” involved. In [8,9] a qualitative concept of best approximation is formulated. Roughly, a qualitatively best transitive approximation of a graph is a transitive graph which cannot be “improved” without also going against the original graph. A quantitative concept of best approximation goes back at least to [10]. A quantitatively best transitive (...) approximation is a transitive graph that makes the minimal number of mistakes against the original graph. In other words, the sum of the edges that are removed from and are added to the original graph is minimal. (shrink)

Eric Davidson was a legend both in his science and his personality. He inspired and challenged a new generation of developmental biologists and I was lucky to be one of them. He changed the way we think about biological interactions by synthesizing a large scale, almost incomprehensible set of data into a causal model of a gene regulatory network. While his death leaves a big hole in our lives, his contribution to the conceptualization of regulatory biology will inspire developmental and (...) evolutionary biologists for decades to come.

It is shown that quantum mechanics cannot be formulated as a stochastic theory involving a probability distribution function of position and momentum. This is done by showing that the most general distribution function which yields the proper quantum mechanical marginal distributions cannot consistently be used to predict the expectations of observables if phase space integration is used. Implications relating to the possibility of establishing a "hidden" variable theory of quantum mechanics are discussed.

[ES]Una historia de la ontología que pretenda dar cuenta de su acontecer de manera integral y equilibrada, ha de considerar tanto los aspectos historiográficos y filosóficos de sus fuentes así como los relativos a su contexto socio-cultural y necesariamente en relación con los de la metafísica, pues sus historias están indisolublemente ligadas, aunque ello no significa que necesariamente sean las mismas. En este trabajo, se intenta de manera elemental y mínima bosquejar dichas consideraciones, a través de una breve revisión historiográfica (...) de distintas nociones y hechos que puedan configurar una base sólida para la constitución de la historia de la ontología e interpretación de su significado y naturaleza. [EN] A history of ontology that pretends to be an integral and well-balanced account of its development, must considerer the historiographical and philosophical aspects of its sources, as well as the relation with its socio-cultural context, and necessarily, the relation with the same aspects of Metaphysics, as both histories are inextricably related, without necessarily being the same. In this work, it is intended, in a minimal way, to outline such considerations, trough a brief historiographic revision of the distinctive facts and notions that can configure a solid ground for the constitution of the history of ontology and the interpretation of its significance and nature.

In this paper I present an overview of the doctrine known as Positive Aesthetics regarding aesthetic judgements about nature. According to this view, all pristine nature is always beautiful and, generally, although not necessarily, human intervention tends to introduce ugliness in nature. One of the strong practical motivations behind this claim is an attempt to ground our reasons to preserve natural environments in aesthetic reasons. Positive Aesthetics has been defended within contrary approaches to nature appreciation such as the cognitivists and (...) the anti-cognitivist. Recently, the possibility of real ugliness in nature has been defended; at the same time, it is argued that the presence of ugly items in nature does not lead necessarily to the idea that they are not aesthetically valuable. Hence, natural ugliness can be a reason to preserve nature. In this sense, the denial of the Positive Aesthetics claim is shown to be compatible with the appeal to aesthetic negative qualities as a source of reasons for preserving natural environments.

About a month after his 83rd birthday Raphael Robinson was almost wholly incapacitated by a massive stroke, and 8 weeks later, on January 27, 1995, he died of ensuing complications. Mathematics was his life. He was always working on problems—those brought to him in journals or by colleagues, and others that he invented. Just three days before his death he received word that a paper of his, originating in a published problem, was accepted for publication. His 64 publications spanned a (...) full 6 decades, and included significant papers on number theory, combinatorics, complex analysis, and geometry, in addition to logic and set theory.Robinson was born on November 2, 1911, in National City, California. He came to Berkeley to study mathematics, obtaining an A.B. in 1932, an M.A. in 1933, and his Ph.D. in December, 1934. His dissertation was in complex analysis. He took 12 graduate courses in a variety of fields, but not one was close to logic or set theory—which was later the setting of about a quarter of his publications.After completing his studies Robinson served as Instructor for two years at Brown University, then returned for good to Berkeley in 1937, reaching the rank of full Professor in 1949. He taught a great variety of courses and was known as an excellent teacher, but was most interested in problemsolving and research and in 1972, at age 61, he elected early retirement, at considerable financial sacrifice, in order to concentrate on these pursuits.

L'A. propose ici une lecture de la Bible, philosophique et en recherche de la sagesse. Il illustre cela en recherchant dans l'étude de la Bible ce qu'il appelle le rêve humaniste qui revient sans cesse de la société rationnelle. Parce que la Bible enseigne, la plupart du temps, non par argumentation, mais par récits, il propose de s'arrêter sur la première histoire concernant ce thème, celle de la ville et de la tour de Babel, racontée dans le livre de la (...)

This paper focuses on the conceptual relationship between rationality and progress as applied to scientific development. The concept of methodology is used in the sense of a model of scientific change. It is argued, as against e.g. recent discussion by Larry Laudan, that progress implies rationality. The notion of rationality useful for this conception of scientific development includes instrumental rationality, butalso the idea of rational paradigm-shift, which is analysed in terms of changes of conceptual frameworks. The key idea is the (...) posibility of a rational reconstruction of series of conceptual frameworks, where the shift from one framework to its successor may be reconstructed as rational in the sense of there being reasons in the successor for accepting the change, and thus the whole series being rational.

There is some cost to you in voting. While it may be small for some, it is significant for others. Some people go to a great deal of effort just to vote. What return do they get for this effort? Zilch! A single vote can only impact an election when there is a tie, which has essentially zero chance of happening in a state or national election. The typical response to this is "Well, what if everyone did that?" Of course, (...) that would be a disaster. But we are not talking about everyone, we are talking about ONE individual. (shrink)
