    Theoricity, observation and homology: a response to Pearson.Ariel Jonathan Roffé, Santiago Ginnobili & Daniel Blanco - 2018 - History and Philosophy of the Life Sciences 40 (3):42.
    An interesting metatheoretical controversy took place during the 1980’s and 1990’s between pattern and phylogenetic cladists. What was always at stake in the discussion was not how work in systematics should be carried out, but rather how this practice should be metatheoretically interpreted. In this article, we criticize Pearson’s account of the metatheoretical factors at play in this discussion. Following him, we focus on the issue of circularity, and on the role that phylogenetic hypotheses play in the determination of “primary (...)

    Dynamic Homology and Circularity in Cladistic Analysis.Ariel Jonathan Roffé - 2020 - Biology and Philosophy 35 (1):21.
    In this article, I examine the issue of the alleged circularity in the determination of homologies within cladistic analysis. More specifically, I focus on the claims made by the proponents of the dynamic homology approach, regarding the distinction between primary and secondary homology. This distinction is sometimes invoked to dissolve the circularity issue, by upholding that characters in a cladistic data matrix have to be only primarily homologous, and thus can be determined independently of phylogenetic hypotheses, by using the classical (...)

    Genetic Drift as a Directional Factor: Biasing Effects and a Priori Predictions.Ariel Jonathan Roffé - 2017 - Biology and Philosophy 32 (4):535-558.
    The adequacy of Elliott Sober’s analogy between classical mechanics and evolutionary theory—according to which both theories explain via a zero-force law and a set of forces that alter the zero-force state—has been criticized from various points of view. I focus here on McShea and Brandon’s claim that drift shouldn’t be considered a force because it is not directional. I argue that there are a number of different theses that could be meant by this, and show that one of those theses—the (...)

    Optimality Models and the Propensity Interpretation of Fitness.Ariel Jonathan Roffé & Santiago Ginnobili - 2020 - Acta Biotheoretica 68 (3):367-385.
    The propensity account of fitness intends to solve the classical tautologicity issue by identifying fitness with a disposition, the ability to survive and reproduce. As proponents recognized early on, this account requires operational independence from actual reproductive success to avoid circularity and vacuousness charges. They suggested that operational independence is achieved by measuring fitness values through optimality models. Our goal in this article is to develop this suggestion. We show that one plausible procedure by which these independent operationalizations could be (...)

    Against a Metaphysical Understanding of Rejection.Mariela Rubin & Ariel Roffé - 2018 - Principia: An International Journal of Epistemology 22 (1):189-202.
    In this article, we defend that incorporating a rejection operator into a paraconsistent language involves fully specifying its inferential characteristics within the logic. To do this, we examine a recent proposal by Berto for a paraconsistent rejection, which — according to him — avoids paradox, even when introduced into a language that contains self-reference and a transparent truth predicate. We will show that this proposal is inadequate because it is too incomplete. We argue that the reason it avoids trouble is (...)

  9. The Key Role of Underlying Theories for Scientific Explanations. A Darwinian Case Study.Daniel Blanco, Ariel Roffé & Santiago Ginnobili - 2020 - Principia: An International Journal of Epistemology 24 (3):617-632.
    A given explanatory theory T falls into circular reasoning if the only way to determine its explanandum is through the application of T. To find an underlying theory T′ that determines T′s explanandum helps us save T from this accusation of circularity. We follow the structuralist view of theories in presenting and dealing with this issue, by applying it to particular theories. More specifically, we focus on the relationship between the Darwinian theory of common ancestry and the determination of homologies.

  10. Dos usos de los modelos de optimalidad en las explicaciones por selección natural.Santiago Ginnobili & Ariel Roffé - 2017 - Metatheoria 8 (1):43-55.
    Resumen -/- El objetivo de este trabajo consiste en analizar las relaciones entre los modelos de optimalidad y la selección natural. Defenderemos que esas relaciones pueden dividirse en dos tipos, en tanto hay dos tipos de explicaciones seleccionistas, que llamaremos “históricas” y “ahistóricas”. Las explicaciones históricas revelan como una población dada adquiere un rasgo que es adaptativo en ese ambiente e involucran muchas generaciones, variación, etc. Las explicaciones ahistóricas, explican por qué, en determinado momento, ciertos tipos de organismos tienen un (...)

    How questions and why questions interact in complex ways within biological practice. One of the most fruitful accounts to think about this relation is the widely known systemic approach, which has its origin mainly in the works of Robert Cummins (1975, 1983). As we will show, this approach effectively manages to capture much of what biologists do, especially in areas such as molecular biology, neuroscience and neuroethology. Our aim with this work is to discuss the metatheoretical status of the presuppositions (...)

    Drift as Constitutive: Conclusions From a Formal Reconstruction of Population Genetics.Ariel Jonathan Roffé - 2019 - History and Philosophy of the Life Sciences 41 (4):55.
    This article elaborates on McShea and Brandon’s idea that drift is unlike the rest of the evolutionary factors because it is constitutive rather than imposed on the evolutionary process. I show that the way they spelled out this idea renders it inadequate and is the reason why it received some objections. I propose a different way in which their point could be understood, that rests on two general distinctions. The first is a distinction between the underlying mathematical apparatus used to (...)

    El estatus fáctico de la cladística: aportes desde una reconstrucción estructuralista.Ariel Jonathan Roffé - 2020 - Metatheoria – Revista de Filosofía E Historia de la Ciencia 11 (1):53-72.
    The present work analyzes the controversy within biological systematics regarding the status of cladistics. The use of the parsimony method for phylogenetic reconstruction has been defended by appealing to a methodological principle of simplicity, as well as to empirical principles that external to systematics. I propose new kind of approach, which consists in considering it an empirical theory, thus justifying its application by its empirical success. To defend this point, a formal structuralist reconstruction of cladistics will be provided, which will (...)

    Reconstructor: A Computer Program That Uses Three-Valued Logics to Represent Lack of Information in Empirical Scientific Contexts.Ariel Jonathan Roffé - 2019 - Journal of Applied Non-Classical Logics 30 (1):68-91.
    ABSTRACTIn this article, I develop three conceptual innovations within the area of formal metatheory, and present a computer program, called Reconstructor, that implements those developments. The first development consists in a methodology for testing formal reconstructions of scientific theories, which involves checking both whether translations of paradigmatically successful applications into models satisfy the formalisation of the laws, and also whether unsuccessful applications do not. I show how Reconstructor can help carry this out, since it allows the end-user to specify a (...)

    En este ambicioso libro, el biólogo Daniel W. McShea y el filósofo de la biología Robert N. Brandon desafían las explicaciones explícitas encontradas en la litera-tura acerca del origen de la diversidad y la complejidad en los seres vivos. Estas explicaciones recurren en su mayoría a la acción de la selección natural, como ser, a la selección diversificadora/disruptiva, a la selección de niveles superiores favoreciendo a especies/clados con mayor propensión a la especiación, o a las ventajas de una mayor división (...)

    Sobre la capturabilidad de teorías informales en sistemas axiomáticos formales.Ariel Jonathan Roffé - 2014 - Cuadernos de Filosofía 62:65-75.
    El objetivo de este artículo es analizar qué quiere decir capturar una teoría (se utilizará la aritmética como ejemplo paradigmático) por medio de un sistema axiomático formal. Se considerarán para ello dos enfoques, que pueden denominarse “semántico” y “sintáctico”, tanto en términos de sus ventajas como de sus limitaciones. El enfoque semántico (presupuesto por Barrio y Da Ré en este volumen y expuesto en la primera sección), entiende la expresabilidad como una restricción de la clase de los modelos; se muestra (...)

    The meta-theoretical status of ZFEL.Ariel Jonathan Roffé & Santiago Ginnobili - 2019 - Humanities Journal of Valparaiso 14:57-73.
    In a recent book, McShea and Brandon argue that the observed diversity and complexity of life are explainable by a principle they call the “zero-force evolutionary law” or “ZFEL”. Although this principle would be implicit in many explanations given by biologists, it would have never been made explicit. Assuming that this idea is interesting, and that the authors are right, we will discuss the metatheoretical way in which they present said principle, as being a part of probability theory. This allows (...)
