Este artículo es una aproximación al carácter político de las mafias que protegen el tráfico de drogas desde una perspectiva mencionada pero poco tratada dentro del concepto mismo de mafia: la articulación de intereses de amplios grupos sociales dentro de su oferta de protección. Tanto las mafias de la droga que gozan de dominación social como las que no tienen mayor interacción social toman decisiones dirigidas a la imposición de sus intereses. La gran diferencia está en que las decisiones de (...) las primeras tienden a involucrar la estructura social que ha sido transformada por el narcotráfico. Cualquier intento por reprimir a las mafias involucra ahora un ataque a los intereses estructurales de amplios sectores sociales. Un caso concreto servirá para ilustrar esta lectura política del narcotráfico: la guerra de Pablo Escobar contra el estado. (shrink)

Mill’s socialism and democratic theory have led some scholars to accuse him of trying to eliminate conflict from political life. Whereas Graeme Duncan has averred that Mill’s socialism aims to institute a completely harmonious society, James Fitzjames Stephen has contended that Millian democracy sought to evacuate conflict from political discussion. This article reconstructs both critiques and argues they are imprecise. Even if disputes motivated by redistribution of material goods would no longer exist in an egalitarian society, conflicts driven by (...) resentment over social reputation would keep the flame of conflict burning in a Millian socialist community. Moreover, a close reading of Considerations on Representative Government shows that Mill knew that no amount of political discussion is able to make conflicting opinions disappear. According to him, conflict is unavoidable in democratic politics because citizens analyse political issues from different social perspectives. Mill’s goal was not to eliminate conflict, but rather to regulate it in such a way as to bring about its attendant benefits, namely, progress and self-development. (shrink)

We provide a 'verisimilitudinarian' analysis of the well-known Linda paradox or conjunction fallacy, i.e., the fact that most people judge the probability of the conjunctive statement "Linda is a bank teller and is active in the feminist movement" (B & F) as more probable than the isolated statement "Linda is a bank teller" (B), contrary to an uncontroversial principle of probability theory. The basic idea is that experimental participants may judge B & F a better hypothesis about Linda as compared (...) to B because they evaluate B & F as more verisimilar than B. In fact, the hypothesis "feminist bank teller", while less likely to be true than "bank teller", may well be a better approximation to the truth about Linda. (shrink)

Starting from the sixties of the past century theory change has become a main concern of philosophy of science. Two of the best known formal accounts of theory change are the post-Popperian theories of verisimilitude (PPV for short) and the AGM theory of belief change (AGM for short). In this paper, we will investigate the conceptual relations between PPV and AGM and, in particular, we will ask whether the AGM rules for theory change are effective means for approaching the truth, (...) i.e., for achieving the cognitive aim of science pointed out by PPV. First, the key ideas of PPV and AGM and their application to a particular kind of propositional theories - the so called "conjunctive propositions" - will be illustrated. Afterwards, we will prove that, as far as conjunctive propositions are concerned, AGM belief change is an effective tool for approaching the truth. (shrink)

Admitiendo la distinción propuesta por Mayr entre biología funcional y biología evolutiva, sugerimos que estos dos dominios de investigación siguen dos distintos modos de considerar lo viviente que pueden ser entendidos, pero en dos sentidos diferentes, como teleológicos. Para distinguir esas dos formas de teleología hacemos una comparación entre la explicación funcional típica de la biología funcional y la explicación seleccional propia de la biología evolutiva. Cada uno de estos tipos de explicación obedece a una regla metodológica especial: la explicación (...) funcional sigue al principio de adecuación autopoiética; y la explicación seleccional sigue al principio de adecuación adaptativa. Pero, mientras el primero será presentado como estando subordinado a un principio general da causación; el segundo será presentado como siendo independiente de él. Finalmente, en el contexto de una breve discusión relativa al concepto de symmorphosis, sostenemos que, en la biología contemporánea, la noción de adecuación adaptiva es preeminente sobre la noción de adecuación funcional: esta encuentra su fundamento en aquella.Admitting Mayr’s distinction between functional and evolutionary biology we suggest that these two dominions of inquiry follow two different modes of onsider the living that can be considered, but in two different senses, as being teleological. To distinguish these two forms of teleology we make a comparison between the functional explanation, typical of functional biology, and the selective explanation, proper of evolutionary biology. Each one of this kind of explanation obeys an special methodological rule: the functional explanation follows the principle of autopoietic adequacy; and the selective explanation follows the principle of adaptive adequacy. But, while the former principle will be presented as being subordinated to a general principle of causation; the later will be presented as being independent of it. Finally, in the context of a brief discussion concerning the concept of symmorphosis, we argue that, in contemporary biology, the notion of adaptive adequacy is preeminent over the notion of functional adequacy: the later find its fundament in the former.

The Darwinian revolution supposed and imposed a much broader and more complex concept of environment than that which, until that moment, had been considered by most as part of natural history. Until Darwin, the environment of living beings had been regarded, almost exclusively, as the inanimate surroundings. This pre-Darwinian notion of environment included physicochemical and climatic variables: the living beings themselves were scarcely considered, or they were regarded just as food to be assimilated. In contrast, with Darwin, the influence of (...) living surroundings began to be regarded as having decisive importance for understanding the distribution, configuration, and viability of living beings. The relationships established among different living beings became the main and more significant features of the biological environment. This conceptual change was an exigency derived from the formulation and justification of the theory of natural selection. The idea of struggle for existence supposed by that theory requires that the biotic environment be considered critical in determining the viability of each living being. (shrink)

La distinción propuesta por Ernst Mayr y François Jacob entre biología funcionaly biología evolutiva es una clave fundamental para un tratamiento claro y concluyente de dos problemas que, recurrentemente, se colocan en el ámbito de la Filosofía de la Biología: aquel que atañe al posible carácter teleológico de las explicaciones biológicas y aquel relativo a la autonomía de la Biología en relación a la Física y a la Química. Sin sostener una alternativa de solución para ninguno de estos problemas, presentamos (...) esa oposición mostrando su relevancia para el tratamiento de tales cuestiones. Nuestra idea es que las mismas no deberían plantearse sin especificar a cual de los dos dominios de la ciencias de la vida nos estamos refiriendo.Mayr’s and Jacob’s distinction between functional biology and evolutionary biology is a fundamental key for a clearer and more conclusive treatment of two problems that, currently, are discussed in Philosophy of Biology: that which matter to the teleological character of biological explanations and that which matter to the autonomy of Biology from Physic and Chemistry. Without hold any alternative solution for none of these problems, we present that opposition showing its relevance for the treatment of both questions. Our idea is that these problems shouldn’t be posed without a specification of the domain of Biology that is being considered. (shrink)

Las presiones selectivas no son factores ambientales que existan independientemente de los linajes por ellas afectados. Su existencia y su configuración siempre dependen de las alternativas de evolución que el propio linaje genera y acepta; y dicha configuración, necesariamente, se va alterando conforme el propio linaje evoluciona. Aclarar eso es muy importante para desestimar algunas reticencias generadas por la dicotomía próximo-remoto. Esta polaridad continúa siendo un recurso conceptual válido e insustituible para entender la especificidad de la Biología Evolucionaria. Enmendar algunos (...) equívocos generados por Mayr en su caracterización del concepto de causa remota es una alternativa mejor que la de pensar en abandonar o en relativizar esa distinción.

Although the knowledge about biological systems has advanced exponentially in recent decades, it is surprising to realize that the very definition of Life keeps presenting theoretical challenges. Even if several lines of reasoning seek to identify the essence of life phenomenon, most of these thoughts contain fundamental problem in their basic conceptual structure. Most concepts fail to identify either necessary or sufficient features to define life. Here, we analyzed the main conceptual frameworks regarding theoretical aspects that have been supporting the (...) most accepted concepts of life, such as (i) the physical, (ii) the cellular and (iii) the molecular approaches. Based on an ontological analysis, we propose that Life should not be positioned under the ontological category of Matter. Yet, life should be better understood under the top-level ontology of “Process”. Exercising an epistemological approach, we propose that the essential characteristic that pervades each and every living being is the presence of organic codes. Therefore, we explore theories in biosemiotics and code biology in order to propose a clear concept of life as a macrocode composed by multiple inter-related coding layers. This way, as life is a sort of metaphysical process of encoding, the living beings became the molecular materialization of that process. From the proposed concept, we show that the evolutionary process is a fundamental characteristic for life’s maintenance but it is not necessary to define life, as many organisms are clearly alive but they do not participate in the evolutionary process (such as infertile hybrids). The current proposition opens a fertile field of debate in astrobiology, epistemology, biosemiotics, code biology and robotics. (shrink)

En la Teoría de la Selección Natural, el concepto de función biológica debe suponerse para delimitar el concepto de aptitud; y éste debe suponerse para delimitar el concepto de adaptación y también para explicar el fenómeno al que este último alude.

El concepto de función biológica es un caso particular del concepto general de función; y el concepto de aptitud especifica el concepto de eficiencia.

The concept of biological function is a particular case of the general concept of function; and the concept of fitness is a specification of the concept of efficiency.

La idea de herencia extendida se ha transformado en un leitmotiv de lo que se ha dado en llamar ‘síntesis extendida’. Dicha idea, entretanto, lleva a ignorar una de las marcas distintivas de lo que clásicamente se ha entendido por transmisión hereditaria: su estrecha asociación con el proceso de reproducción. Sin considerar tal asociación, la noción de herencia, más que ampliarse, de hecho se disuelve; y aceptar esa disolución acarrearía demasiadas dificultades para el discurso de las ciencias biológicas. Una de (...) esas dificultades tiene que ver con el concepto de variación hereditaria. Con la disolución de la noción de herencia, ese concepto también se disolvería; y, sin éste, la Teoría de la Selección Natural no puede articularse. Pero, no habiendo motivos valederos para aceptar semejante costo teórico, aquí quiero mostrar que ambos conceptos, el de herencia y el de variación hereditaria, pueden y deben ser elucidados sin aceptar la idea de herencia ampliada.

This is the introductory essay to the Italian translation of Anthony de Jasay's "Choice, contract, and consent. A restatement of liberalism".

The main cognitive target of Ecology is the functional analysis of the ecological processes and systems. It does not suppose, meanwhile, that these processes and systems are designed systems and processes like individual leaving beings. The Ecology, likewise Physiology, is constitutively guided by the presupposition of a privileged state , to be explained, that it is the persistence of the systems and processes that she studied; and its functional analyses obey to this presupposition. Ecology supposes an ideal of natural order (...) , under which consideration this privileged state is thinking as an improbable state of things and, for that, needed of explanation; and, in what concerns this latter point, the analogy between Ecology and Physiology can also result instructive.

This article examines the changing scope and method of ecumenical public theology from the World Missionary Conference of 1910 until the present. Most changes were made in response to the changing ideological and political contexts. The collapse of liberalism and the social gospel was followed by a type of confessional ethics which arose directly out of the German Church Struggle. In opposition to this there emerged a realist ecumenical social ethics, much indebted to Reinhold Niebuhr, and of Ronald Preston. This (...) type of public theology and its distinctive ‘middle axiom’ method are examined and contrasted with the more recent public theologies which were influenced by liberation theology and grassroots movements. It is suggested that the ending of the Cold War and the fundamental changes that have taken place since September 11 2001 present a radically new kind of challenge to public theology. (shrink)

In The Philosophy of Information, Luciano Floridi presents a theory of “strongly semantic information”, based on the idea that “information encapsulates truth” (the so-called “veridicality thesis”). Starting with Popper, philosophers of science have developed different explications of the notion of verisimilitude or truthlikeness, construed as a combination of truth and information. Thus, the theory of strongly semantic information and the theory of verisimilitude are intimately tied. Yet, with few exceptions, this link has virtually pass unnoticed. In this paper, we briefly (...) survey both theories and offer a critical comparison of strongly semantic information and related notions, like truth, verisimilitude, and partial truth. (shrink)

RESUMEN: La idea de selección interna, propuesta originalmente por Lancelot Whyte, no sólo sirve para entender el papel causal que los constreñimientos del desarrollo tienen en evolución; sino que además puede hacernos comprender de qué modo esos factores organísmicos o internos, cuya importancia la Biología Evolucionaria del Desarrollo hoy quiere rescatar, son pasibles de ser considerados desde una perspectiva variacional o seleccional compatible, pero no asimilable, a la Teoría de la Selección Natural. Así, considerado como un concepto autónomo y diferente (...) al de selección natural, el concepto de selección interna puede permitirnos comprender de qué modo eso que Wallace Arthur llama developmental bias constituye una causa, efectiva y positiva, de transformacionesevolutivas irreversibles y acumulables.ABSTRACT: The idea of internal selection, originally proposed by Lancelot Whyte, not only helps to understand the causal role that the developmental constraints have in evoltion, but it can also show how these organismic or internal factors, which relevancy the Evolutionary Developmental Biology remarks today, can be considered from a variational or selectional perspective that is compatible with, but not reducible to, Natural Selection Theory. Thus, being considered as a concept autonomous and different from natural selection, the concept of internal selection can allow us to understand how that phenomenon that Wallace Arthur calls developmental bias constitutes an effective and positive cause of irreversible and cumulative evolutionary changes.

En los últimos años, algunos autores han venido sosteniendo que la validez de la representación arborescente del patrón filético generado por la evolución está siendo menoscabada por el reconocimiento del impacto evolutivo que tendrían la transferencia genética horizontal, la simbiogénesis, la especiación por hibridación y la introgresión. Esa concepción o representación cladogenética de la evolución sólo nos dejaría ver un aspecto parcial de las relaciones de filiación que conectan a los diferentes linajes de seres vivos; ocultando otro aspecto cuya representación (...) más adecuada sería un reticulado de relaciones entre taxones. Con todo, aún sin poner en tela de juicio la frecuencia y la relevancia explicativa de dichos fenómenos, en este trabajo se intentará mostrar que su admisión y reconocimiento no tiene por qué ir en detrimento de esa concepción cladogenética de la evolución cuya relativización se está pregonando. Por el contrario, la comprensión y la representación de tales fenómenos supone dicha concepción. Palabras clave: Filogénesis, Especiación por hibridación, Introgresión, Simbiogénesis, TGH. (shrink)

Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for (...) is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

Asumiendo y profundizando la distinción entre Biología Funcional y Biología Evolutiva conforme ha sido propuesta por Ernst Mayr y François Jacob, comparamos la naturaleza de los procedimientos experimentales que se realizan en uno y otro dominio de las ciencias de la vida. En vistas a esto, introducimos ciertas precisiones sobre las nociones de observación y experimento e intentamos elucidar los presupuestos sobre los que se apoya la experimentación en biología funcional. A continuación, presentamos los fundamentos y las particularidades de los (...) procedimientos experimentales desarrollados en el contexto de ese capítulo de la biología evolutiva que es la genética de poblaciones, y analizamos las peculiaridades de las variables sobre la que estos se ejercen. Esto nos permite mostrar la diferencia radical que existe entre operar sobre variables poblacionales y operar sobre variables fisiológicas.In this article we compare the nature of the experimental procedures that are carried out in different areas of biology. This is done by accepting and deepening the distinction between Functional and Evolutive Biology as it is argued for by Ernst Mayr and François Jacob. Keeping this in mind, we introduce some remarks on the notions of observation and experiment and try to clear up the presuppositions on the basis of which experimentation in Functional Biology rest. In the wake of it, we show the foundations and the main aspects of those experimental procedures that are developed in the context of that chapter of Evolutive Biology called Genetics of Populations and analyze the peculiarities of the variables by which those experiments are carried out. This allows us to show the radical difference between working on population and physiological variables. (shrink)

A survey of some game-theoretic accounts of the emergence and evolution of spontaneuous cooperation in social and public-good dilemmas.

Having as starting point that a proximal cause is one which effects can be registered in the states of an individual organism, in this work I will argue that what defines an ultimate cause is the fact that its effects can be registered in the evolution of lineages, and not simply in population states. This, on the other hand, not only will allow us to clarify how the developmental constraints can be understood as causes of the evolutionary phenomena; but also (...) it will allow us to point the eminently historical character of Developmental Evolutionary Biology that Wallace Arthur lessened in Biased Embryos and Evolution. Thus, and following this latter reasoning, I will also try to show that, although the action of developmental constraints could happen beyond the limits of a population or a particular species, that does not imply that we are before a comeback of typological thought in Evolutionary Biology.

Research in modern biology has largely been developed according to two main ways of inquiry, as they were outlined by Charles Darwin and Claude Bernard. Each stands for a specific approach to the living corresponding to two different methodological rules: the principle of natural selection and the principle of causation.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

Focusing on the work of Friedrich von Hayek and Vernon Smith, we discuss some conceptual links between Austrian economics and recent work in behavioral game theory and experimental economics. After a brief survey of the main methodological aspects of Austrian and experimental economics, we suggest that common views on subjectivism, individualism, and the role of qualitative explanations and predictions in social science may favour a fruitful interaction between these two research programs.
