%0 Journal Article %T Peirce, la Abducci¨®n y la Investigaci¨®n Cient¨ªfica %A Roberto Espejo %J Revista Observaciones Filos¨®ficas %D 2008 %I Pontificia Universidad C¨¢tolica de Valpara¨ªso %X In this paper C.S. Peirce¡¯s concept of abduction is explored. To this goal Peirce¡¯s notion of abduction as a mode of inference is articulated to the other two classical modes: induction and deduction. The importance of this concept, as a way to explain the creation of an explicative hypothesis for a certain phenomenon, is shown. That gives to abduction an important role in the search for a model or a theory of scientific research. Finally, Peirce¡¯s proposition of the existence of a ¡°rational instinct¡± that could give a fundament to his conception of abduction, based in his metaphysical assumptions, is discussed. %K Abduction %K Rational Instinct %K Modes of Inference %K Scientific Research %K C.S.
