"Rational sufficiency has been a root-concept in philosophy ever since the Greeks. Kant’s Copernican Turn is largely motivated by the wish to save this concept after Berkeley’s reduction of its classic formulation (representationalism). This, as post-Kantians were quick to point out, is a highly problematic move. It’s only with Kierkegaard though that an attempt is made to subject the Kantian formulation to an *internal* critique. His own thinking about human communication is meant to be a successor-notion to Kant’s transcendental reason. This is the real background of Wittgenstein’s Tractatus and the linguistic turn. By recasting the concept in a rigorously semantic form, he shows its incoherence and so its inapplicability to philosophy as a whole. This reduction cuts much deeper than most Wittgensteinians think.
