In the philosophy of science, abstraction has usually been analyzed in terms of the interface between our experience and the design of our concepts. The often implicit assumption here is that such interface has a definite identifiable and universalizable structure, determining the epistemic correctness of any abstraction. Our claim is that, on the contrary, the epistemic grounding of abstraction should not be reduced to the structural norms of such interface but is also related to the constraints on the cognitive processes (...) of specific abstractions. This suggests that we should understand abstraction as embodied in different kinds of abstraction practices. (shrink)

En este texto se examina críticamente la teoría combinatoria de las representaciones científicas de Andoni Ibarra y Thomas Mormann. El núcleo de la crítica va dirigido a mostrar que una serie de estudios sobre la ciencia, que ellos mismos mencionan, sugiere que la clasificación en tipos de representaciones propuesta es problemática. Es más, esos mismos estudios muestran que por lo menos muchas representaciones tienen una dimensión histórica que parece imposible capturar por medio del tipo de formalismo propuesto. /// Ibarra and (...) Mormann's combinatorial theory of scientific representations is subject to critical scrutiny. It is argued that the classification of types of representations offered cannot serve as a basis for an analysis of the variety of representations that happen to arise in science. Empirical studies on ways of representing used in science strongly suggest that a formal theory of representations of the kind proposed is not able to capture the historical dimension of the structure of representations.

RESUMEN: Una tendencia importante en la filosofía de la educación contemporánea toma de la sociología del conocimiento la manera de entender la naturaleza del conocimiento científico. Esta tendencia parte de una crítica al "cognitivismo" individualista, asociado con una concepción tradicional del conocimiento y defiende una posición consensualista según la cual el conocimiento es la búsqueda de consenso. El objetivo del trabajo es mostrar que los consensualistas asumen una falsa dicotomía. Contrario a lo que los consensualistas asumen la cognición puede entenderse (...) a la vez como un logro social y como el resultado del ejercicio de capacidades individuals. Concluyo haciendo ver algunas consecuencias del abandono de esa dicotomía para entenderel papel de la autoridad en la educación.ABSTRACT: An important trend in contemporary philosophy of education follows a view of knowledge promoted by sociologists of knowledge. According to this view a critique of the cognitive individualism implicit in the traditional account of knowledge leads to "consensualism ", the view that knowledge is the search for consensus. The aim of this paper is to show that the consensualists assume a false dichotomy. Cognition can be understood both as a social achievement and as the display of individual capacities. I conclude by exploring some consequences of the abandoning of this dichotomy for our understanding of the role of authority in education. (shrink)

This paper explores some of the philosophical difficulties involved in the task of clarifying the idea of an irreducible statistical law, by means of an analysis of the paradigmatic example of such a law in the Quantum theory.These are two alternative strategies that can be pursued in clarifying this question. One is to understand this irreductibility by means of one or another interpretation of the Quantum theory. But, as will be shown, the different interpretations of Quantum mechanics lead to radically (...) different and fundamentally incompatible answers to the problem. The second strategy is to try to caracterize this irreducibility “directly”, via a proof of the impossibility of a hidden-variable extension of the statistical formalism of the theory. This strategy culminates with Bell’s theorem which indeed establishes the impossibility of constructing “Iocal” theories of hidden variables. This impossibility result, however, fails to provide us with a satisfying interpretation of the quantum irreductibility, rather, it merely shows how far we are from a solution to the problem.

Usual derivations of Lilders's projection rule show that Liuders's rule is the rule required by quantum statistics to calculate the final state after an ideal (minimally disturbing) measurement. These derivations are at best inconclusive, however, when it comes to interpreting Liuders's rule as a description of individual state transformations. In this paper, I show a natural way of deriving Liiders's rule from well-motivated and explicit physical assumptions referring to individual systems. This requires, however, the introduction of a concept of individual (...) state which is not standard. (shrink)

An interpretation of quantum mechanics that rejects hidden variables has to say something about the way measurement can be understood as a transformation on states of individual systems, and that leads to the core of the interpretive problems posed by Luders' projection rule: What, if any, is its physical content? In this paper I explore one suggestion which is implicit in usual interpretations of the rule and show that this view does not stand on solid ground. In the process, important (...) aspects of the role played by the projection postulate in the conceptual structure of quantum mechanics will be clarified. It will be shown in particular that serious objections can be raised against the (often implicit) view that identifies the physical relation of compatibility preserved by Luders' rule with the relation of simultaneous measurability.

I construct a quantum-logical model of the type of situation that seems to be at the root of the problem of interpreting the projection postulate (Luders' rule) as a criterion of minimal disturbance. It is shown that the most natural way of characterizing minimal disturbance leads to contradictory conclusions concerning the final state.
