In a conflict between two people, one person wants one thing and the other wants something else and they think they can't both have what they want. Suppose that what they want can only be the outcome of some joint action. Adam must do either y or z and Eve either y ' or z ' – here y -and- y ' would be one joint action, y -and- z ' would be another, and so on. Adam wants the outcome (...) of his doing z while Eve is doing y '. Eve wants the outcome of her doing z ' while Adam is doing y. Each thinks that these outcomes can't both be had. (shrink)

We resolve a useful formulation of the question how a statistician can coherently incorporate the information in a consulted expert’s probability assessment for an event into a personal posterior probability assertion. Using a framework that recognises the total information available as composed of units available only to each of them along with units available to both, we show: that a sufficient statistic for all the information available to both the expert and the statistician is the product of their odds ratios (...) in favour of the event; that the geometric mean of their two probabilities specifies a contour of pairs of assertions in the unit-square that yield the same posterior probability; that the information-combining function is parameterised by an unknown probability for the event conditioned only on the unspecified information common to both the statistician and the expert; and that an assessable mixing distribution over this unspecified probability allows an integrable mixture distribution to represent a computable posterior probability. The exact results allow the identification of the subclass of coherent probabilities that are externally Bayesian operators. This subclass is equivalent to the class of combining functions that honour the principles of uniformity and compromise. (shrink)

The study of human origins is a kaleidoscopic field, a multitude of objects, reflections, and disciplines a swirl in an ever-changing tumult. The extreme diversity of the elements of information that are indispensable to this field of study (teeth, bones, apes, genes, ancient objects, present-day objects, biomechanical factors, cultural constructions …) appears all by itself to be enough to consign any attempt at synthesis to the realm of the Utopian. It hardly seems reasonable to expect the disparate sciences that fuel (...) the field (paleoanthropology, archaeology, molecular biology, physics, psychology, and others) and the contradictory conceptions of scientific activity that they defend (human sciences, natural sciences, experimental sciences, exact sciences) to be joined with any regularity. As for formulating an overall problematics of the interdependent phenomena encountered in the field, one would have to be more than optimistic to entertain such dreams. And yet this is exactly the program that prehistory and paleoanthropology are laboring to construct tinder the label “the study of the origins of man,” an expression that includes both diachronic processes (human evolution) and activities or behaviors from particular moments, elements that are exceedingly difficult to compare given the separation of their geographic and temporal contexts.

"Die Tat" concerns the effort to recapture a particular memory. In searching to recover that memory trace the writer discovers that the memory datum itself diffuses and breaks up into the present remembering action of the one who remembers. The essay anatomizes that process of diffusion, and tries to come up with a definition of memory.

Most traditional systems of metaphysics do not seem to assert that there are such things as propositions. This appears to me to be a defect in such systems, especially as each such system is really itself a class of propositions or a single complex proposition.

Recent years have featured the existence of a variety of structuralisms, with an important partition between methodological versus philosophical structuralism. Inside philosophical structuralism, many trends can be identified, corresponding to various ontological stances. We argue here that another main partition has contributed to organize structuralism in the twentieth century, rooted in different technical and theoretical interests. This partition is largely transversal to the ones classically identified. Concretely, the paper will focus on possible differences between an arithmetical and logical notion of (...) structure that can be traced back to the writings of Bertrand Russell and Rudolf Carnap, and a mathematical notion of structure, exemplified in the works by Bourbaki. This coexistence gives rise to a fundamental ambiguity that affects contemporary structuralism. Philosophically, in one case the attention is rather centered on a foundational and reductionist perspective, as featured by the Whitehead-Russell Principia and the Carnapian project of the Aufbau: the scientific construction of the world around the idea of structure. In the other, the focus is on epistemological and dynamical issues, as exemplified by two key issues in Bourbaki’s treatise: understanding the architecture of mathematics, offering a tool-kit to mathematicians. These two distinct meanings still coexist inside contemporary scientific practices and lead to different theoretical interests, as we will show thanks to various recent examples. (shrink)

The hypothesis that every class of facts has an explanation is never refuted by evidence, But is confirmed every time any hypothesis is confirmed. Hence, It is the most highly confirmed hypothesis of all, And, Therefore, Should be considered to be true. If it is true, Then there is an explanation of the class of all facts, And this explanation may be identified with god.

This is an important new book about human motivation, about the reasons people have for their actions. What is distinctively new about it is its focus on how people see or understand their situations, options, and prospects. By taking account of people's understandings, Professor Schick is able to expand the current theory of decision and action. The author provides a perspective on the topic by outlining its history. He defends his new theory against criticism, considers its formal structure, and shows (...) at length how it resolves many currently debated problems: the problems of conflict and weakness of will, Allais' problem, Kahneman and Tversky's problems, Newcomb's problem, and others. The book will be of special interest to philosophers, psychologists, and economists. (shrink)

A partir de los años 90, la expansión del capitalismo y la globalización ubicaron a las fronteras como espacios privilegiados para el intercambio de bienes, servicios y personas. Paralelamente, y en consecuencia, también se convirtieron en el lugar de movimiento de aquellos actos considerados como delitos y de aquellas personas consideradas como criminales. En este marco, aparecerán las llamadas nuevas amenazas a la seguridad, que ya no se circunscriben a una ideología o territorio determinado, sino que tienen múltiples (des)localizaciones. Los (...) nuevos riesgos serán el terrorismo, el narcotráfico, la trata de personas y los migrantes, en sus diversos procesos de movilidad y asociados directamente al terrorismo. En este artículo, propongo entonces analizar los marcos internacionales y regionales para identificar narrativas y actores, internacionales y regionales, involucrados en el proceso de (in)securitización de la migración, a través del cual esta aparece dentro del espectro de las nuevas amenazas, principalmente aquella catalogada como irregular. A partir del análisis de documentos, intentaré hacer un aporte en relación a la construcción del sujeto terrorista en el Cono Sur, identificando cómo la migración se convierte también en un posible vector del riesgo terrorista a través de la figura del asilo y el refugio —migración forzada.
