I have had a great deal of trouble trying to figure out the argument between Hegel and Jacob Fries. One one hand I can see valid points in each. If the whole issue is immediate knowledge,-- well that question seems to have been taken care of by Michael Huemer when he writes about reason having direct awareness of things. It might need to understand what is a line in the first place, but after that it can see immediately that two lines can not make  a closed figure but three lines can.   

I think that the major problem is when philosophy slides into politics.  So I can see that a visceral reaction against totalitarian regimes  would give people a pause about Hegel's concept of the State. [Maybe more than a pause.]]

[And the odd thing is that nothing of the Constitution of the USA had anything to do with  almost any philosophy at all. Even though Thomas Jefferson was a great admirer of John Locke, but he had little of nothing to do with the Constitution which was more of less the product of James Madison.]

My basic impression is that the train of thought of Fries , Leonard Nelson and Kelley Ross [called the Kant Fries school] is about the best thing. Still I can see a lot of valid points in Hegel. So the extent of the disagreement seems to be over done.
