From the "Critique of the Kantian Philosophy," an Appendix to The World as Will and Representation:

[T]he most injurious result of Kant's occasionally obscure language is, that it acted as exemplar vitiis imitabile; indeed, it was misconstrued as a pernicious authorisation. The public was compelled to see that what is obscure is not always without significance; consequently, what was without significance took refuge behind obscure language. Fichte was the first to seize this new privilege and use it vigorously; Schelling at least equalled him; and a host of hungry scribblers, without talent and without honesty, soon outbade them both. But the height of audacity, in serving up sheer nonsense, in stringing together senseless and extravagant mazes of words, such as had previously only been heard in madhouses, was finally reached in Hegel, and became the instrument of the most ponderous general mystification that has ever taken place, with a result which will appear fabulous to posterity, and will remain as a lasting monument of German stupidity.
