Questions in Logic

This dissertation pursues two tightly interwoven goals: to bring out the relevance of questions for the field of logic, and to establish a solid theory of the logic of questions within a classical logical setting. These enterprises feed into each other: on the one hand, the development of our formal systems is motivated by our considerations concerning the role to be played by questions; on the other hand, it is via the development of concrete, workable logical systems that the potential of questions in logic is made clear and tangible.

Política

El Arte de la Transición

El triunfo electoral y la superación de dinámicas caotizadoras post-electorales requiere inevitablemente un centro de poder conductor, que esté en relación dialéctica real con las masas y los bloques de poder. Lo que sucede, cuando por falta de liderazgo no se establece la direccionalidad e integración necesaria de las fuerzas de transformación estatales y sociales en una gobernanza nacional adecuada, lo vemos en Venezuela y, crecientemente, en Argentina, Brasil, Estados Unidos y Nicaragua. La entropía del sistema aumenta y se acerca al punto del colapso vía el magnicidio, el golpe militar, el levantamiento de masas o la intervención externa.

Computational reverse mathematics and foundational analysis

Reverse mathematics studies which subsystems of second order arithmetic are equivalent to key theorems of ordinary, non-set-theoretic mathematics. The main philosophical application of reverse mathematics proposed thus far is foundational analysis, which explores the limits of different foundations for mathematics in a formally precise manner. This paper gives a detailed account of the motivations and methodology of foundational analysis, which have heretofore been largely left implicit in the practice. It then shows how this account can be fruitfully applied in the evaluation of major foundational approaches by a careful examination of two case studies: a partial realization of Hilbert’s program due to Simpson [1988], and predicativism in the extended form due to Feferman and Schutte. Shore [2010, 2013] proposes that equivalences in reverse mathematics be proved in the same way as inequivalences, namely by considering only ω -models of the systems in question.

Respuesta a un crítico de la teoría del cierre

Análogamente, el cero es una representación gráfica de una operación consistente en dejar un hueco, un lugar vacío, en un ceremonial político-religioso propio de una sociedad de castas que ya posee la escritura como era la de la India. Lo que explicaría por qué los indios –que no tenían un Euclides o un Arquímedes– conocieron el cero. Pero el número cero terminó segregándose de este contexto técnico (Gustavo Bueno, Prólogo a Historia de la Lógica de Julián Velarde, Universidad de Oviedo, Oviedo, 1989, p. XIII). Escribir los numerales en rojo no hace que los números sean rojos, porque también podrían haberse trazado con tinta negra o azul. Esta neutralización de la subjetualidad ligada a los contextos técnicos, mediante un mecanismo de reducción-absorción, es condición de posibilidad del cierre categorial de las matemáticas.

Church’s Theorem and the Analytic-Synthetic distinction in Mathematics

” Kant’s classification of mathematical truth as synthetic a priori has given rise to a very considerable literature on the subject. We will limit ourselves here to discussing a recent attempt to vindicate Kant in terms of certain results in contemporary first order logic. In a series of letures delivered at Oxford in the early sixties, J. Hintikka has proposed formal explications of the Kantian distinction between analytic and synthetic truths and arguments. Entitled “An Analysis of Analyticity”, “Are Logical Truths Tautologies? “, “Kant Vindicated”, and “Kant and the Tradition of Analysis”, these lectures now form a central part of Hintikka’s book Logic, Language Games and Infom1ation : Kantian Themes in the Philosophy of Logic(Oxford, 1973); henceforth references to Hintikka’s presentation will simply be given by the appropriate page number in the book. We shall first give an overview of Hintikka’s arguments, then examine then criticallly, and finally argue for Church’s Theorem as a superior formal vindication of Kant’s position.

The World Wants You to Think Like a Realist

Last but not least, if you think like a realist, you’re likely to be skeptical about the ambitious schemes that idealists keep dreaming up to bring an end to conflict, injustice, inequality, and other bad things. Striving to build a safer and more peaceful world is admirable, but realism reminds us that the ambitious efforts to remake world politics always create unintended consequences and rarely deliver the promised results. It also reminds that even allies fear unchecked power and will have misgivings whenever the United States tries to run the world. If you think like a realist, in short, you are more likely to act with a degree of prudence, and you’ll be less likely to see opponents as purely evil (or see one’s own country as wholly virtuous) and less likely to embark on open-ended moral crusades. Ironically, if more people thought like realists, the prospects for peace would go up.

Opinion

Science and Methaphysics

The idea that there is a difference in principle between science and metaphysics, and not only a difference but an opposition, is about as old as science itself (and by ‘science’ we mean modem science as it has e:xisted for the last three or four hundred years). It became generally accepted by the men of science themselves in the seventeenth century, at least after the influence of the Cartesians had been broken. For Descartes could not, of course, accommodate such a delimitation as his whole philosophy was one great attempt to merge science and metaphysics into one. But he already had to reckol with contemporaries who thought differently.

Analyticity, Truthmaking and Mathematics

Whereas for many truths, truthmaker theory offers a plausible account, there are certain kinds of truths for which the theory seems less helpful: principally (though not exclusively) analytic truths. I argue that an augmentation of the usual idea of truthmakers can solve this problem. Moreover that once solved we are able to look afresh at the nature of mathematics, whether conceived as analytic or synthetic, necessary or contingent, and reduce the ontological options. I also argue that it was Quine’s reformulation of analyticity, deployed in place of the correct Leibniz-Wolff-Kant account, which led to his holistic account of knowledge and pragmatist account of scientific revisability.

PDVSA: Cifras y Producción Julio 2018

Julio ha sido un mes de malas noticias para Venezuela. Su ya esquelética cadena de producción y medios de subsistencia tradicional siguen siendo vulnerados, asaltados y manejados como bodegas; con mentalidad de bodeguero y PDVSA no escapa de esa realidad. La industria petrolera está asfixiada; estrangulada. Eso lo saben sus socios extranjeros y como todo buen negociador, toman ventaja de cualquier situación de debilidad de su contraparte.

An Explication of the Concept “Analogy”

In this article we have tried to give an explicit interpretation to the concept “analogy”, which, according to us-is used too often in an intuitive way without explicit definition. In this interpretation we have constructed a quantification function for analogy. This quantification function is dependant on a digital automaton but under certain conditions extendible to an analog automaton. We have tried to prove that this quantitative function is a distance function.

Probabilistic Causal Analysis of Social Influence

Mastering the dynamics of social influence requires separating, in a database of information propagation traces, the genuine causal processes from temporal correlation, homophily and other spurious causes. However, most of the studies to characterize social influence and, in general, most data-science analyses focus on correlations, statistical independence, conditional independence etc.; only recently, there has been a resurgence of interest in “causal data science”, e.g., grounded on causality theories. In this paper we adopt a principled causal approach to the analysis of social influence from information-propagation data, rooted in probabilistic causal theory. Our approach develops around two phases. In the first step, in order to avoid the pitfalls of misinterpreting causation when the data spans a mixture of several subtypes (“Simpson’s paradox”), we partition the set of propagation traces in groups, in such a way that each group is as less contradictory as possible in terms of the hierarchical structure of information propagation.
