¿QUÉ SON LOS DIAGRAMAS GEOMÉTRICOS? UNA APROXIMACIÓN KANTIANO-PEIRCEANA

What kind of objects are the diagrams, which can be manipulated logically and mathematically and through it to obtain knowledge? In this paper, I wish to propose a way to answer this question. I will sustain the view, inspired by Kant and Peirce, that diagrams constitutes a kind of hybrid objects with a intelectual and a sensible side. The logician or the mathematician are interested in an structure that is instantiated in the diagram, although not perfectly. This, in virtue of its sensible character and its accesibility allows the manipulation, the experimentation, but in virtue of kind of the relations that it entails, makes posible the production of judgments with universal scope.Keywords: Diagrams, schemes, universals, geometry, Kant, Peirce
