Aristóteles y el principio de (no) contradicción; fundamentación teórica y práctica

Abstract

A theoretical dialogue demands the validity of at least the weak form of the principie of (non) contradiction as a pragmatic-trascendental condition. The practical dialogues require the strong form of the above mentioned principie as such a pragmatic necessary condition. This paper displays shortly the problems of foundation of the different forms of the principie and discusses their application domains.
