Post-Kantian philosophy feverishly reclaimed intellectual intuition as a guarantee of its high claims

Evidence

As soon as the history of philosophy asserted through Kant, explicitly and expressly, although not for the first time, the simultaneous conceivability of an intellectual intuition and its impossibility in the realm of experience, variousalmost feveredattempts broke out to try to win this concept back for philosophy as a guarantee of its most elevated claims. These attempts started with Fichte, Schlegel, Novalis and Schelling. — Rolf Wiggershaus, The Frankfurt School, 346
