De la evolución de las especies a la evolución de las ciencias

Resum

In the ocassion of Darwin's centenary, toulmin's evolutive epistemology in stressed, within other modern epistemological currents, which are considered as fixist or evolutive in character. This epistemology distinguishes different levels of scienctifical change, and uses the Darwinian model to explain continuity and.change in the scientifical disciplines. The dynamical concept of rationality which emerges from this study, can be useful for teaching sciences in a more humanistic way.
