Habermas and Apel share with the
wittgensteinian linguistic turn the main issue which is at
stake in the latter. That is: they rely on the linguisticalpragmatic
substitution of the traditional Cartesian (and
Kantian) subject of representation, thought as the nonempirical
and non-objective pre-condition of the possibility
of the objective world, with the function of linguistic and
communicative interaction as a means of subjective and
intersubjective world-disclosure (H. Sluga 1996;
Wittgenstein, Tlp, § 5.54- 5.55). The issue basically
concerns the way we think about language as a system
and a means of representation. What is here at stake is
actually the source of its normativity, and the way in which
this normativity can be rationally founded
