GRAMMATISCHER REALISMUS: EINE ANALYSE ZUM WITTGENSTEIN´SCHEN BEGRIFF DER „GRAMMATIK“

Abstract

This text deals with Wittgenstein's concept of “grammar”, which is one of the “key concepts” of his “Philosophical Investigations”. This term is interpreted here as a type of transcendental argument, i.e. as a regressive argument of the form: "In order to to explain why such and such (the observed - e.g. language as an institution) exists, one must presuppose that such and such (the unobserved – grammar) exists." The main thesis of the analysis proposed here is that Wittgenstein had to introduce in his philosophical investigations the concept of “grammar” as something predetermined in the perspective of “grammatical realism” to provide a theory of language with the aim of explaining the possibility of intersubjective language use, without having to fall back on any universal properties of language (in the sense of classical metaphysics).
