obscurantism

Kant employed technical terms that were not commonly understood. Schopenhauer contended that post-Kantian philosophers such asFichte, Schelling, and Hegel deliberately mimicked Kant's way of writing. "Because of his style which was obscure, Kant was properly understood by exceedingly few. And it is as if all the philosophical writers, who since Kant had had some success, had devoted themselves to writing still more unintelligibly than Kant. This was bound to succeed!"
