In Transformation of Philosophy Apel rejected the destructive function of paradoxes of sense criticism in Wittgenstein’s Philosophical Investigations, without accepting the systematic radicalisation of initial antimetaphysical programmatic projects. In this respect, Apel proposed a positive use of these paradoxes, reconstructing the quasi-transcendental turn by which P. Winch prolonged the proposals of Wittgenstein, in spite of their insufficiency.
