    On natural selection and Hume's second problem
    Evolution and Cognition 4 (2): 156-172. 1998.
    David Hume's famous riddle of induction implies a second problem related to the question of whether the laws and principles of nature might change in the course of time. Claims have been made that modern developments in physics and astrophysics corroborate the translational invariance of the laws of physics in time. However, the appearance of a new general principle of nature, which might not be derivable from the known laws of physics, or that might actually be a non-physical one (this means co…Read more

    Martín Heidegger y la cuestión de la tecnología
    Ciencia y Desarrollo 14 (83): 75-85. 1988.
    La pregunta sobre la esencia de la tecnología no atañe sólo a la filosofía, sino que tiene un alcance más vasto y una repercusión más general; transforma cualitativamente la relación entre el hombre y la tecnología al añadir un elemento fundamental: la libertad.

    Back to the future: Aristotle and molecular biology
    Ludus Vitalis 15 (28): 195-198. 2007.
    The Aristotelian axiom that function follows form was beautifully instantiated in molecular biology by the discovery of DNA’s structure that immediately suggested how DNA might work as depository and vehicle for genetic information. However, later on molecular biology became infatuated with the gene that became the center of the universe. This gene-centered viewpoint is an obstacle for the emerging field of evo-devo aiming at finding the causal connections between evolution and biological develo…Read more

    Synthetic life, what for and what future?
    Ludus Vitalis 19 (36): 213-215. 2011.
    This text answers the question, posed by the editor, on the philosophical and social issues resulting from the synthetic assembly of a modified bacterial genome that was introduced in an existing bacterial species (M.mycoides)and so it was claimed to represent the first ever kind of synthetic life produced by human manipulation.

    The unit of selection is the concept of that ‘something’ to which biologists refer when they speak of an adaptation as being ‘for the good of’ something. Darwin identified the organism as the unit of selection because for him the ‘struggle for existence’ was an issue among individuals. Later on it was suggested that, in order to understand the evolution of social behavior, it is necessary to argue that groups, and not individuals, are the units of selection. The last addition to this debate was…Read more

    Towards a morphogenetic perspective on cancer
    Rivista di Biologia/Biology Forum 95 35-62. 2002.
    The purpose of this paper is to present a critique of the current view that reduces cancer to a cellular problem caused by specific gene mutations and to propose, instead, that such a problem might become more intelligible, if it is understood as a phenomenon that results from the breakdown of the morphological plan or Gestalt of the organism. Such and organism, in Aristotelian terms, is characterized for presenting a specific morphe or logos (form) and for having a telos (end) to fulfill. A mal…Read more

    ¿Existen los descubrimientos científicos?
    Ciencia y Desarrollo 16 (93): 85-97. 1990.
    Considerar un evento como descubrimiento científico es tarea compleja que, casi siempre, se ve influida por la sistematización de las investigaciones, la publicación de los hallazgos, o las ideas sobre la realidad del contexto donde se presenta.

    Los límites del reduccionismo molecular
    Ciencia y Desarrollo 20 (116): 18-25. 1994.
    Existen inconsistencias fundamentales entre el paradigma de la biología molecular y el paradigma de la física contemporánea y, por lo tanto, el marco conceptual vigente en la biología molecular resulta insuficiente para abordar las cuestiones del origen y desarrollo de la forma y organización biológicas.

    Darwin's two hundred years: is not time for a change?
    Ludus Vitalis 17 (32): 87-99. 2009.
    Two hundred years after Darwin’s birth, the evolution of living systems is an accepted fact but there is scope for controversy on the mechanisms involved in such a process. Mainstream neo-Darwinism champions the role of natural selection (NS) as the fundamental cause of the evolutionary process as well as of random, contingent events at the genetic level as the main source of variation upon which NS performs its causal role. Thus, according to neo-Darwinism the course of biological evolution is …Read more

    For some the gene-centered reductionism that permeates contemporary neo-Darwinism is an obstacle for finding a common explanatory framework for both biological and cultural evolution. Thus social scientists are tempted to find new concepts that might bridge the divide between biology and sociology. Yet since Aristotle we know that the level of explanation must be commensurate with the particular question to be answered. In modern natural science there are many instances where a reductionist appr…Read more

    La crítica posmoderna de la ciencia: una genealogía francesa
    Ciencia Ergo Sum 4 (2): 223-229. 1997.
    Postmodern thought has focused itself on the critique of modern epistemology that was founded on a clear distinction between the knowing subject and the object of knowledge. For postmodern thought such a distinction is non-existent or dubious at best. Postmodernism has carried to its logical conclusion the postulates of structuralism; therefore, for postmodern thought there is no general intrinsic meaning in a fact of thing, but there are only particular ways for attributing meaning to such fact…Read more

    Molecular biology is a relatively new and very successful branch of science but currently it faces challenges posed by very complex issues that cannot be addressed by a traditional reductionist approach. However, despite its origins in the providential shift of some theoretical physicists to biology, currently molecular biology is immersed in a blind trend in which high-throughput technology, able to generate trillions of data, is becoming the leading edge of a discipline that has traded rationa…Read more

    Naturalistic ethics. Is there such a thing?
    Ludus Vitalis 14 (25): 217-220. 2006.
    There is a current, ultra-Darwinian trend for finding in the process of evolution by natural selection the roots of our ethical behavior. In such a way that ethics may become a branch of biology. Nevertheless, this preposterous notion is supported on previous naive assumptions of contemporary biology that have already been falsified by recent results of research in genomics and molecular biology.

    Since Aristotle the central question in biology was the origin of organic form; a question put in the backyard by neo-Darwinism that considers organic form as a side effect of the interactions between genes and their products. On the other hand, the fashionable notion of self-organization also fails to provide a true causal explanation for organic form. For Aristotle form is both a cause and the principle of intelligibility and this coupled to the classical concepts of potentiality and actuality…Read more

    Ciencia y Democracia ¿Cuál es la relación?
    Ludus Vitalis 24 (46): 147-150. 2016.
    Los editores de la revista han planteado dos preguntas: ¿Están los ciudadanos en condiciones de incorporar el espíritu científico en sus deliberaciones públicas? ¿Es esto requisito necesario para la democracia? Así, este artículo pretende ofrecer una respuesta que va más allá de tales preguntas.

    The current mainstream in cancer research favours the idea that malignant tumour initiation is the result of a genetic mutation. Tumour development and progression is then explained as a sort of micro-evolutionary process, whereby an initial genetic alteration leads to abnormal proliferation of a single cell that leads to a population of clonally derived cells. It is widely claimed that tumour progression is driven by natural selection, based on the assumption that the initial tumour cells acqui…Read more

    Chance and necessity are mainstays of explanation in current biology, dominated by the neo-Darwinian outlook, a blend of the theory of evolution by natural selection with the basic tenets of population genetics. In such a framework the form of living organisms is somehow a side effect of highly contingent, historical accidents. Thus, at a difference of other sciences, biology apparently lacks theoretical principles that in a law-like fashion may explain the emergence and persistence of the chara…Read more

    Cosas tan diversas como el progreso de la mecánica cuántica y la caída del muro de Berlín han precipitado en una crisis a las filosofías materialistas, como el atomismo y el materialismo dialéctico. A la luz de estos hechos, el darwinismo, producto del siglo XIX que se sustenta en una visión materialista de la existencia, revela con mayor claridad sus inconsistencias epistemológicas. Sin embargo, los biólogos todavía no inventan un relato mejor que el propuesto por Darwin. Así, el presente traba…Read more

    La Complejidad y la Forma
    Fondo de Cultura Económica. 1997.
    This book deals with embryology although it is not a book on embryology. It is in itself like a developing embryo and at a difference of textbooks it does not pretend to be an introduction to any particular scientific discipline. This work was born from a fascination about forms and it is the draft of a morphological process: the account of a form coming into being, the form of an as yet unnamed but emerging science. A new science of qualities in which the natural phenomena are understood as who…Read more
