A virada evolucionária de Kuhn
(Universidade Federal do Piauí, 2015) DIAS, Elizabeth de Assis
In the present paper, we intended to demonstrate the reformulation Kuhn has made of the conception of scientific development he advanced in The structure of scientific revolutions in order to reconcile it with his idea of progress that leads to specialization of knowledge. This reformulation started to be outlined in the final chapter of the referred work when Kuhn drew an analogy between the scientific development and the Darwinian evolution. However, it only started to gain importance in the writings that followed The structure of scientific revolutions in the 1990s when he deepened the analogy in terms of speciation. Kuhn started then to conceive the development of science as evolutionary. His attention focuses on a pattern of development by the means of proliferation of specializations in the same format of the phenomenon of speciation in biological evolution. This new pattern is illustrated by the metaphor of the “tree of knowledge”.
