    José Díez & Pablo Lorenzano (2015). Are Natural Selection Explanatory Models a Priori? Biology and Philosophy 30 (6):787-809.
    The epistemic status of Natural Selection has seemed intriguing to biologists and philosophers since the very beginning of the theory to our present times. One prominent contemporary example is Elliott Sober, who claims that NS, and some other theories in biology, and maybe in economics, are peculiar in including explanatory models/conditionals that are a priori in a sense in which explanatory models/conditionals in Classical Mechanics and most other standard theories are not. Sober’s argument focuses on some “would promote” sentences that (...)

    En esta trabajo se analiza la relación existente entre las propuestas de Mendel, de los "redescubridores" -de Vries, Correns y Tschermak-, de Bateson y colaboradores y de Morgan y discípulos, e.e. la historia de la genética "clásica", en términos de "inconmensurabilidad", de forma tal de capturar y precisar tanto la idea de que entre éstas se dan ciertas discontinuidades y rupturas como de que éstas tienen "algo" que ver de algún modo entre sí. En particular, se introducen, con ayuda del (...)

    José Díez & Pablo Lorenzano (2013). Who Got What Wrong? Fodor and Piattelli on Darwin: Guiding Principles and Explanatory Models in Natural Selection. [REVIEW] Erkenntnis 78 (5):1143-1175.
    The purpose of this paper is to defend, contra Fodor and Piattelli-Palmarini (F&PP), that the theory of natural selection (NS) is a perfectly bona fide empirical unified explanatory theory. F&PP claim there is nothing non-truistic, counterfactual-supporting, of an “adaptive” character and common to different explanations of trait evolution. In his debate with Fodor, and in other works, Sober defends NS but claims that, compared with classical mechanics (CM) and other standard theories, NS is peculiar in that its explanatory models are (...)

    Pablo Lorenzano (2013). Los aspectos erotéticos de la ciencia: el caso de la genética. Revista de Filosofia Aurora 25 (36):13-41.
    The aim of this paper is to show, in the line suggested by Nickles (1980, 1981) and developed by Sintonen (1985, 1996), not just that the problem-solving approach and the theory approach are not incompatible, but also that the latter, in the version of the semantic conception of theories known as “structuralist view”, can be used to give precision to the problem-solving approach, by a more precise characterization of the theoretical context in which problems arise and, in this way, to (...)

    Scientific activity produces results of various types. In particular, science produces a special kind of knowledge or knowledges, assumed to be different from knowledge or common sense knowledge, from everyday experience and formulated in ordinary language; a more systematized knowledge, with greater range and accuracy, and intersubjectively controllable. To produce this kind of knowledge (or knowledge), we introduce new concepts, formulate hypotheses and laws and, ultimately, construct theories, being the result of a practice or specific activity, considering science as (perhaps), (...)

    Wolfgang Balzer & Pablo Lorenzano (2000). The Logical Structure of Classical Genetics. Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 31 (2):243-266.
    We present a reconstruction of so-called classical, formal or Mendelian genetics using a notation which we believe is more legible than that of earlier accounts, and lends itself easily to computer implementation, for instance in PROLOG. By drawing from, and emending, earlier work of Balzer and Dawe (1986,1997), the present account presents the three most important lines of development of classical genetics: the so-called Mendel's laws, linkage genetics and gene mapping, in the form of a theory-net. This shows that the (...)

    Different conceptions of scientific theories, such as the state spaces approach of Bas van Fraassen, the phase spaces approach of Frederick Suppe, the set-theoretical approach of Patrick Suppes, and the structuralist view of Joseph Sneed et al. are usually put together into one big family. In addition, the definite article is normally used, and thus we speak of the semantic conception of theories and of its different approaches .

First, the proposals of reconceptualization of the standard notions of partial potential model, intended application and empirical claim of a theory made by Balzer (1982, 1988, 1997a, 1997b, 2006, Balzer, Lauth & Zoubek 1993) and Gähde (1996, 2002, 2008) will be first discussed. Then, the distinction between “global” and “local empirical basis” will be introduced, linking it with that (...)

    The aim of this paper is to further develop van Fraassen’s diagnosis, expanding a previous analysis of the fundamental law of classical genetics and the status of the so-called ‘Mendel’s laws’.6 According to this diagnosis the Hardy-Weinberg law: 1) cannot be considered as axiom (or fundamental law) for classical population genetics, since it is a law that describes an equilibrium that 2) holds only under certain special conditions, and 3) only determines a subclass of models, 4) whose generalized form (and (...)

    The question posed by the title is usually answered by saying that the “synthesis” between the theory of evolution by natural selection and classical genetics, which took place in 1930s-40s, would have taken place much earlier if Darwin had been aware of Mendel and his work. What is more, it nearly happened: it would have been enough if Darwin had cut the pages of the offprint of Mendel’s work that was in his library and read them! Or, if Mendel had (...)

La segunda pretende dar cuenta de las causas de que la sangre se mueva y la denominamos teoría de las causas del movimiento de la sangre. En este trabajo, presentamos (...)

This reconstruction has been carried out with the instruments, duly modified and extended with respect to the case under consideration, of the structuralist conception of theories. The so-called Mendel’s Laws, as well as linkage genetics and gene mapping are formulated in a precise manner while the global structure of genetics is represented as a theory-net. These (...)
