Abstract

The theme of knowledge certainty and of enouncements’ universality the classical issue of radical skepticism synthesized by the necessity of an a priori proof for the reality of the external world, the conscience issue, the status of the object and objectivity, and also the subject-object bound are themes which influenced fundamentally the paradigm of philosophical postmodernism. Before Nietzsche have said that “the world became a story”, Kant himself faced (rather indirectly) the impossibility of offering an a priori proof for the external world: we can now (thoroughly) only in the limits of the phenomena and of an object determined by our epistemic inter-subjectivity.
