Hay lo que queda: Sobre la presunta tautologicidad de la teoría de la selección natural

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.
