Karl-Otto Apel and the Critique of Meaning

This work emphasizes the influence in Apel of the named Critique of Meaning developed by Wittgenstein and Peirce. We reconstruct the foundations of the recognition of a linguistic a priori, and of the semiotic-anthropological radicalization, that leads to the conception that man can be understood as thought-sign. It also shows the way Apel believes that such thought-sign is inscribed in the context of a supraindividual enviroment, where it develops its own individuality. From that approach, a transformation of the subject function in the interpreter function of the signs has to be done in order to create a new answer to the problem of intersubjectivity.
