The scientific revolution of the XVII siècle is normally described as erasing final causes and the teleology of physics. Nevertheless, the functional language plays a central role in certain areas of biological practice. This is why many philosophers have tried to explicate the concept of function, sometimes to defend the relevance of its use, some other times to show that it is merely a way of speaking that could be easily eliminated without any relevant information loss. The principal purpose of (...) this paper is to show the necessity of appealing to functional concepts for an adequate reconstruction of the Darwinian natural selection theory. Thus, functional language is used in the conceptualization of the theory’s domain of application, and that domain should be determined independently of the natural selection theory. (shrink)

RESUMEN: El tema de este trabajo es la reconstrucción de la teoría de la selección natural darwiniana. Me propongo esbozar la ley fundamental de esta teoría de manera informal a partir de sus aplicaciones en El origen de las especies de Darwin y presentar sus conceptos fundamentales. Presentaré la red teórica de leyes especiales que surgen de la especialización de esta ley fundamental. Supondré el estructuralismo como marco metateórico. Señalaré también algunas consecuencias que mi propuesta tiene sobre ciertas discusiones metateóricas (...) en torno a la teoría y, finalmente, relacionaré mi reconstrucción con otras reconstrucciones disponibles.ABSTRACT: This paper is about the reconstruction of the Darwinian Theory of Natural Selection. My aim here is to outline the fundamental law of this theory in an informal way from its applications in The Origin of Species and to make explicit its fundamental concepts. I will introduce the theory-nets of special laws that arisefrom the specialization of the fundamental law. I will assume the metatheoretical structuralist frame. I will also point out many consequences that my proposal has about a few metatheoretical discussions around the theory and, finally, I will relate my propose to other reconstructions available.

Do the sciences aim to uncover the structure of nature, or are they ultimately a practical means of controlling our environment? In Instrumental Biology, or the Disunity of Science, Alexander Rosenberg argues that while physics and chemistry can develop laws that reveal the structure of natural phenomena, biology is fated to be a practical, instrumental discipline. Because of the complexity produced by natural selection, and because of the limits on human cognition, scientists are prevented from uncovering the basic structure of (...) biological phenomena. Consequently, biology and all of the disciplines that rest upon it--psychology and the other human sciences--must aim at most to provide practical tools for coping with the natural world rather than a complete theoretical understanding of it.

The central thesis of this book is that the semantic conception is a logical methodologically and heuristically richer and more accurate account of scientific theorizing, and in particular of theorizing in evolutionary biology, than the ...

Since the introduction of mathematical population genetics, its machinery has shaped our fundamental understanding of natural selection. Selection is taken to occur when differential fitnesses produce differential rates of reproductive success, where fitnesses are understood as parameters in a population genetics model. To understand selection is to understand what these parameter values measure and how differences in them lead to frequency changes. I argue that this traditional view is mistaken. The descriptions of natural selection rendered by population genetics models are (...) in general neither predictive nor explanatory and introduce avoidable conceptual confusions. I conclude that a correct understanding of natural selection requires explicitly causal models of reproductive success. *Received May 2006; revised December 2006. †To contact the author, please write to: Department of Philosophy, Kansas State University, 201 Dickens Hall, Manhattan, KS 66506; e‐mail: [email protected] .

Drawing on work of the past decade, this volume brings together articles from the philosophy, history, and sociology of science, and many other branches of the biological sciences. The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

Traditionally a scientific theory is viewed as based on universal laws of nature that serve as axioms for logical deduction. In analyzing the logical structure of evolutionary biology, Elisabeth Lloyd argues that the semantic account is more appropriate and powerful. This book will be of interest to biologists and philosophers alike.

En uno de los ataques más reiterados a Darwin, que todavía subsiste en la literatura actual, se señala que la teoría de la selección natural es tautológica, analítica o, al menos, irrefutable. En docenas de artículos, diversos autores han señalado las condiciones en que la selección natural quedaría refutada, intentando mostrar que no carece de contenido empírico. La estrategia seguida en este trabajo será otra. Teniendo en cuenta que la crítica de tautologicidad o irrefutabilidad ha sido esgrimida contra leyes fundamentales (...) de otras teorías, insertaré la discusión en un marco metateórico más amplio. Para discutir el estatus del segundo principio de la mecánica clásica, Moulines introduce el concepto de "principio guía". Los principios guía no serían contrastables directamente, sino a través de especializaciones. Desde mi punto de vista, considerar a la selección natural como principio guía permitiría explicar por qué muchos la han considerado tautológica y cómo esto no implica vacuidad. One of the most repeated objections to Darwin, still present in contemporary literature, outlines that theory of natural selection is tautological, analytical or at least irrefutable. There are many authors that point out the conditions in which natural selection would be refuted, trying to prove that it doesn't lack of empirical content. This essay will work on a different strategy. Taking into account that tautological or irrefutable criticism has been put forward against other theories' fundamental laws; I will insert the argumentation in a wider theoretical frame. To argue about the status of the second principle about classic mechanical Moulines introduces the 'guiding principle' concept. The guiding principles wouldn't be directly contrastable. The only way in which they could be contrastable would be through special laws. From my point of view natural selection, considered as the guiding principle, would explain why many thinkers had considered it a tautology and how this does not imply vacuity. (shrink)
