“In general, the student notes written during or after Hegel’s classes should be used with caution … according to Leopold von Henning’s preface (pp. vi–vii) in his edition (1839) of the Encyclopädie of 1830, the editors of the Encyclopedia sometimes changed or completed the sentences in which the students had rendered Hegel’s classes.”

“It may indeed be disconcerting that only today do we doubt ― and not everyone does ― that Hegel’s lectures … are actually reproduced authentically in the published edition … that did not become full–blown for more than a hundred and fifty years. We can hardly examine here all the reasons for this circumstance.”

“Kant’s philosophy is a high one … the march of God in the world, that is what the state is.”
