La investigación sobre el origen de la vida y sus presupuestos filosóficos

Several philosophers have noted that metaphysical naturalism has been an assumption shared by the members of the scientific community involved in the research concerning the origin of life. It is a consequence of this presupposition that the emergence of life should have been very probable under the physical and chemical conditions in the primitive Earth. The state of the research on the origin of life, though, is very far from having a convincing naturalist hypothesis in the terms sought after. The attitude of the researchers and some philosophers has been to suppose that these failures are not reason to think that some other naturalist hypothesis won't work. Here, an epistemological reconstruction of this attitude in Bayesian terms is offered. It is argued that the insulation of metaphysical naturalism from disconfirmation is not rational, and would become an obstacle to the advancement of knowledge.
