Sobre la naturaleza de la duda y de la certeza y de su papel en la vida

Abstract

This work aims to present the role of Doubt and Certainty in our actual and theoretical activities, based upon Ludwig Wittgenstein's On Certainty. In order to do that I first show that real doubt makes sense in light of its actual effects; then, 1compare Wiltgenstein's view with that of Peirce, for whom doubt arises from surprise and moves us to action. Finally, I finish stressing the permanent movement between doubt and certainty as belonging to We itself.
