The evidence of a great mind is there. Deep thoughts, complex thinking are all on display. However, I could not agree with many if not most of his conclusions. Sometimes he would take up contradictory positions. Other times he would state aims and presuppositions that I don't find any basis to hold. Still other times he would state things as "obvious" then move on without explaining how he knows they are obvious, belittling the reader. Is this his style? His translator's style? Is it just what happens when German is translated into English? I don't know. Still, I did learn some from this text, so it was not without purpose.
