One of the most influential studies in all expertise research is de Groot’s (1946) study of chess players, which suggested that pattern recognition, rather than search, was the key determinant of expertise. Many changes have occurred in the chess world since de Groot’s study, leading some authors to argue that the cognitive mechanisms underlying expertise have also changed. We decided to replicate de Groot’s study to empirically test these claims and to examine whether the trends in the data have changed (...) over time. Six Grandmasters, five International Masters, six Experts, and five Class A players completed the think-aloud procedure for two chess positions. Findings indicate that Grandmasters and International Masters search more quickly than Experts and Class A players, and that both groups today search substantially faster than players in previous studies. The findings, however, support de Groot’s overall conclusions and are consistent with predictions made by pattern recognition models. (shrink)
: In this paper I will examine two conceptions of philosophy that were defended in Latin America during the last century. I believe that both models have to be put away and that we must build a new one, recovering elements of both of them. At the end of my paper I will consider very briefly what can we learn from this in order to construct a genuine philosophical dialogue between the United States and Latin America.
This paper offers an exposition of Husserl's mature philosophy of mathematics, expounded for the first time in Logische Untersuchungen and maintained without any essential change throughout the rest of his life. It is shown that Husserl's views on mathematics were strongly influenced by Riemann, and had clear affinities with the much later Bourbaki school.
Against several recent interpretations, I argue in this paper that Immanuel Kant's support for enlightened absolutism was a permanent feature of his political thought that fit comfortably within his larger philosophy, though he saw such rule as part of a transition to democratic self-government initiated by the absolute monarch himself. I support these contentions with (1) a detailed exegesis of Kant’s essay "What is Enlightenment?" (2) an argument that Kantian republicanism requires not merely a separation of powers but also a (...) representative democratic legislature, and (3) a demonstration that each stage of a democratic transition can potentially be in an absolute monarch’s short-run self-interest. I conclude the paper by defending Kant's theory of democratization against charges of consequentialism and paternalism and by pointing out its similarity to other accounts of democratic transitions (for example, those of Samuel Huntington and Guillermo O'Donnell), suggesting a previously unnoticed opportunity for cross-fertilization between political philosophy and comparative politics.

Quine’s criticism of the notion of analyticity applies, at best, to Carnap’s notion, not to those of Frege or Husserl. The failure of logicism is also the failure of Frege’s definition of analyticity, but it does not even touch Husserl’s views, which are based on logical form. However, some relatively concrete number-theoretic statements do not admit such a formalization salva veritate. A new definition of analyticity based not on syntactical but on semantical logical form is proposed and argued for.
This paper is concerned with the use of logic to solve philosophical problems. Such use of logic goes counter to the prevailing empiricist tradition in analytic circles. Specifically, model-theoretic tools are applied to three fundamental issues in the philosophy of logic and mathematics, namely, to the issue of the existence of mathematical entities, to the dispute between first- and second-order logic and to the definition of analyticity.
The current literature on nanoethics focuses on a wide array of topics such as equity, privacy, military, environment, human enhancement, intellectual property, and security. The identification of those topics leads to the adoption of an ethical stance, which we call the in itself dimension . In this article we argue that even though it is correct to identify the areas where ethical problems are imperative to deal with ( in itself dimension ), it is a partial approach. This is because (...) the in itself dimension pays no attention to another ethical stance; one that does not have anything to do with individual or collective responsibilities, but rather with the socio-economic system into which those responsibilities are embedded. We call this second issue the contextual dimension. (shrink)
Possibly the most comprehensive collection of essays on Descartes' scientific writings ever published, this volume offers a detailed reassessment of his scientific work and its bearing on his philosophy. The 35 essays, written by some of the world's leading scholars, cover topics as diverse as optics, cosmology and medicine. The collection looks at Descartes' work in the sciences as an aspect of his natural-philosophical agenda and discusses: the central place of medicine in Descartes' overall project; the connections between his investigations (...) of specific psychological capacities and his ethics of self-government; and the debates and controversies into which he had his followers were drawn, and their role in shaping Cartesian natural philosophy; and other issues.

Husserl's contributions to the nature of mathematical knowledge are opposed to the naturalist, empiricist and pragmatist tendences that are nowadays dominant. It is claimed that mainstream tendences fail to distinguish the historical problem of the origin and evolution of mathematical knowledge from the epistemological problem of how is it that we have access to mathematical knowledge.
Frege had not one but two different notions of sense, namely, that of ?Über Sinn und Bedeutung? and one implicit in a letter to Husserl of 1906 and elsewhere. This last one originates in Frege's notion of conceptual content. The distinction is used to clarify some obscurities in Frege's thought. In the last section a sort of ?explicans? of Frege's notion of conceptual content is introduced and applied to the semantic analysis of mathematics.
We analyze the connections of Lavoisier system of nomenclature with Leibniz’s philosophy, pointing out to the resemblance between what we call Leibnizian and Lavoisian programs. We argue that Lavoisier’s contribution to chemistry is something more subtle, in so doing we show that the system of nomenclature leads to an algebraic system of chemical sets. We show how Döbereiner and Mendeleev were able to develop this algebraic system and to find new interesting properties for it. We pointed out the resemblances between (...) Leibniz program and Lavoisier legacy, particularly regarding the lingua philosophica for understanding and thinking Nature, in this particular case, chemistry. In the second part we discuss, from the linguistic viewpoint, how Lavoisian algebraic system may be taken further to build a language. We study the constituents of such a chemical language. Finally, we formalize some of the ideas here presented by using elements of network theory and discrete mathematics. (shrink)

We review different studies of the Periodic Law and the set of chemical elements from a mathematical point of view. This discussion covers the first attempts made in the 19th century up to the present day. Mathematics employed to study the periodic system includes number theory, information theory, order theory, set theory and topology. Each theory used shows that it is possible to provide the Periodic Law with a mathematical structure. We also show that it is possible to study the (...) chemical elements taking advantage of their phenomenological properties, and that it is not always necessary to reduce the concept of chemical elements to the quantum atomic concept to be able to find interpretations for the Periodic Law. Finally, a connection is noted between the lengths of the periods of the Periodic Law and the philosophical Pythagorean doctrine. (shrink)
This paper discusses Husserl’s views on physical theories in the first volume of his Logical Investigations , and compares them with those of his contemporaries Pierre Duhem and Henri Poincaré. Poincaré’s views serve as a bridge to a discussion of Husserl’s almost unknown views on physical geometry from about 1890 on, which in comparison even with Poincaré’s—not to say Frege’s—or almost any other philosopher of his time, represented a rupture with the philosophical tradition and were much more in tune with (...) the physical geometry underlying the Einstein-Hilbert general theory of relativity developed more than two decades later.

In this article we explore multiple change operators, i.e., operators in which the epistemic input is a set of sentences instead of a single sentence. We propose two types of change: prioritized change, in which the input set is fully accepted, and symmetric change, where both the epistemic state and the epistemic input are equally treated. In both kinds of operators we propose a set of postulates and we present different constructions: kernel changes and partial meet changes.
Agricultural engineers’ jobs are especially related to sustainability and earth life issues. They usually work with plants or animals, and the aim of their work is often linked to producing food to allow people to improve their quality of life. Taking into account this dual function, the moral requirements of their day-to-day professional practice are arguably greater than those of other professions. Agricultural engineers can develop their ability to live up to this professional responsibility by receiving ethical training during their (...) university studies, not only by taking courses specifically devoted to ethics, but also by having to deal with moral questions that are integrated into their technical courses through a program of Ethics Across the Curriculum (EAC).

The cross-cultural literature is reviewed and integrated together with attitude theories, thereby outlining a model through which certain values influence the intervening variables that ultimately lead managers to tolerate employee bribery. The case of Latin America is employed to illustrate how regionally dominant cultural values may shape managers' attitudes, subjective norms, and perceived behavioral control, which in turn affect tolerance of employee bribery. A series of research propositions and practical recommendations are derived from the model.
The dilemma confronted by Buridan’s Ass leads into a problem about nil-preference situations, to which there is a solution in the literature that is inspired by Alan Turing: we have evolved with a computational module in our brains that comes into play in such situations by picking a random action among the alternatives that detennines the subject’s choice. We relate these Buridan’s Ass situations to a larger, theoretically interesting category in which there is no alternative that is decisively superior to (...) others with respect to expected utility, and we try to show how our emotional makeup figures in a rational response, particularly as informed by symbolic utilitythat we draw down from our culture’s shared understandings. The category is theoretically interesting because it contains moral dilemmas, as well as hard cases in which an imponant choice must be made without an option that has clearly superior expected utility. We argue that our Emotional Response Model is preferable to Turing’s Randomizer for this category, as well as more illuminating about nil-preference situations or close approximations thereto.

We propose a revision operator on a stratified belief base, i.e., a belief base that stores beliefs in different strata corresponding to the value an agent assigns to these beliefs. Furthermore, the operator will be defined as to perform the revision in such a way that information is never lost upon revision but stored in a stratum or layer containing information perceived as having a lower value. In this manner, if the revision of one layer leads to the rejection of (...) some information to maintain consistency, instead of being withdrawn it will be kept and introduced in a different layer with lower value. Throughout this development we will follow the principle of minimal change, being one of the important principles proposed in belief change theory, particularly emphasized in the AGM model. Regarding the reasoning part from the stratified belief base, the agent will obtain the inferences using an argumentative formalism. Thus, the argumentation framework will decide which information prevails when sentences of different layers are used for entailing conflicting beliefs. We will also illustrate how inferences are changed and how the status of arguments can be modified after a revision process. (shrink)
By analysing a contemporary criticism to the so called “mathematical chemistry”, we discuss what we understand by mathematizing chemistry and its implications. We then pass to ponder on some positions on the subject by considering the cases of Laszlo, Venel and Diderot, opponents to the idea of mathematization of chemistry. In contrast, we analyse some scholars’ ideas on the fruitful relationship between mathematics and chemistry; here Dirac and Brown are considered. Finally, we mention that the mathematical–chemistry relationship should be considered (...) beyond the mere aspect of whether chemistry is or not able to be mathematized. This discussion is based upon opinions by Kant and Comte, the first one having two positions on chemistry based upon mathematics and the latter mooting the idea of doing chemistry with mathematical spirit.

Designers’ intentions are important for determining an artifact’s proper function (i.e., its perceived real function). However, there are disagreements regarding why. In one view, people reason causally about artifacts’ functional outcomes, and designers’ intended functions become important to the extent that they allow inferring outcomes. In another view, people use knowledge of designers’ intentions to determine proper functions, but this is unrelated to causal reasoning, having perhaps to do with intentional or social forms of reasoning (e.g., authority). Regarding these latter (...) social factors, researchers have proposed that designers’ intentions operate through a mechanism akin to social conventions, and that therefore both are determinants of proper function. In the current work, participants learned about an object’s creation, about social conventions for its use and about a specific episode where the artifact was used. The function implemented by the user could be aligned with the designer’s intended function, the social convention, both, or neither (i.e., an opportunistic use). Importantly, the use episode always resulted in an accident. Data show that the accident negatively affected proper function judgments and perceived efficiency for conventional and opportunistic functions, but not for designers’ intended functions. This is inconsistent with the view that designers’ intentions are conceptualized as causes of functional outcomes and with the idea that designers’ intentions and social conventions operate through a common mechanism.

. Artificial Intelligence (AI) has long dealt with the issue of finding a suitable formalization for commonsense reasoning. Defeasible argumentation has proven to be a successful approach in many respects, proving to be a confluence point for many alternative logical frameworks. Different formalisms have been developed, most of them sharing the common notions of argument and warrant. In defeasible argumentation, an argument is a tentative (defeasible) proof for reaching a conclusion. An argument is warranted when it ultimately prevails over other (...) conflicting arguments. In this context, defeasible consequence relationships for modelling argument and warrant as well as their logical properties have gained particular attention. This article analyzes two non-monotonic inference operators Carg and Cwar intended for modelling argument construction and dialectical analysis (warrant), respectively. As a basis for such analysis we will use the LDSar framework, a unifying approach to computational models of argument using Labelled Deductive Systems (LDS). In the context of this logical framework, we show how labels can be used to represent arguments as well as argument trees, facilitating the definition and study of non-monotonic inference operators, whose associated logical properties are studied and contrasted. We contend that this analysis provides useful comparison criteria that can be extended and applied to other argumentation frameworks. (shrink)
The goal of this study was to introduce a model explaining how managers’ attitudes, subjective norms, attributions, and the individualism–collectivism cultural dimension affect the way managers’ deal with employee bribery in organizations. Twenty-six internal and external attributions related to bribery were identified through a series of structured interviews with 65 subject matter experts. These attributions, together with the other variables in the model, were evaluated by 354 (n = 354) Ecuadorian managers. Hierarchical regression analyses indicated that attitudes and external attributions (...) significantly predicted managers’ intentions to discipline employees who accepted a bribe. In addition, external attributions mediated the relationship between individualism–collectivism and intent to discipline corrupt employees. Implications for the management of bribery in Latin American organizations are discussed. (shrink)
In this article I revisit earlier stages of the discussion of personal identity, before Neo-Lockean psychological continuity views became prevalent. In particular, I am interested in Bernard Williams’ initial proposal of bodily identity as a necessary, although not sufficient, criterion of personal identity. It was at this point that psychological continuity views came to the fore arguing that bodily identity was not necessary because brain transplants were logically possible, even if physically impossible. Further proposals by Shoemaker of causal relations between (...) mental states in our memory and Parfit’s discussion of branching causal chains created additional complications. My contention in this paper is that psychological continuity views deflected our attention from what should have remained in the spotlight all the time: the intersubjective character (or not) of criteria proposed to decide personal identity in our language game, and ultimately our form of life concerning ourselves as persons. B. Williams’ emphasis on the body was not just common sense. It was also recognition of the importance of giving priority to criteria that could be kept under intersubjective control. (shrink)

In this paper six of the most important issues in the philosophy of logic are examined from a standpoint that rejects the First Commandment of empiricist analytic philosophy, namely, Ockham’s razor. Such a standpoint opens the door to the clarification of such fundamental issues and to possible new solutions to each of them.
El objetivo del artículo es reflexionar sobre el concepto de revuelta popular para precisar su valor heurístico en relación con la comunidad política. Para ello se realiza un recorrido teórico de la idea de revuelta popular en algunos textos de Arendt, Rancière, Blanchot, Nancy, Agamben y Esposito. Propongo que la revuelta debe ser entendida en el marco de una ontología de la comunidad. Se concluye que la revuelta popular supone el rechazo de un orden de desigualdad sostenido en un desacuerdo (...) y la exigencia de no perder la comunidad entendida como el lugar mismo de nuestra existencia. The aim of this paper is to reflect on the concept of popular revolt in order to clarify its heuristic value in relation to political community. The essay traces a theoretical trajectory of the idea of popular revolt in some texts of Arendt, Rancière, Blanchot, Nancy, Agamben and Esposito. I propose that popular revolt must be understood in the context of an ontology of the community. I conclude that popular revolt presumes the rejection of an order on inequality sustained by a disagreement and the requirement of not to lose the community understood as the very place of our existence.

La Paradoja de Orayen es dos cosas en una. Primeramente, es un homenaje al filósofo argentino Raúl Orayen (1942–2003). Pocos filósofos hispanoamericanos han gozado de la solidez intelectual y agudeza filosófica de Orayen, y pocos han sido tan queridos. Se trata, pues, de un homenaje bien merecido y que mucho agradecemos los que tuvimos la fortuna de interactuar con Raúl y aprender de él. En segundo lugar, el libro es una contribución a la filosofía hispanoamericana. Alberto Moretti y Guillermo (...) Hurtado tuvieron el acierto de reconocer el valor de un proyecto que la prematura muerte de Orayen dejó inconcluso, y apreciar su potencial para generar discusión filosófica de alto nivel. El resultado es un volumen que recompensará la atención de sus lectores, y dará al trabajo de Orayen justa prominencia en el mundo hispanoamericano. (shrink)
