Concerning him I have always felt, not only what his greatest British admirer said, that his philosophy was "a scrutiny of thought so profound that it was for the most part unintelligible," but also what John Stuart Mill experienced, who "found by actual experience . . . that conversancy with him tends to deprave one's intellect."Eric Voegelin calls him a sorcerer and says,
The author of the Phänomenologie suffers so badly from the existential conflict between his two Selfs that it almost makes no sense to ask what Hegel really meant . . .The "death of God," finally, is unintelligible without the "death of Hegel" . . . by way of a postscript: The death of God is a dangerous plaything for epigonic intellectuals and confused theologians . . . Hegel's obsession was power.
Hegel is quite clear. His classes were the most popular, which annoyed Schopenhauer considerably.
