here is a link to Kelley Ross's PhD thesis on Kant, Fries, and Leonard Nelson. To me it looks like masterpiece.
[Dr. Ross is building his system, and does not spend much time showing the problems with other Neo Kantian schools. Nor with other problems with "Analytic philosophy". [Robert Hanna does a great job in that area.]
But I still have trouble with the arguments on Hegel that tend to be part and parcel of the Kant-Friesian approach.
I just can not see what the problem is. Non intuitive immediate knowledge was a part of Kant's approach as Dr Ross points in Kant's CPR pg 65. ["Immediate" means not through anything. Non intuitive means not through the senses.]
And though Hegel disagrees with this, this disagreement is not a major part of his points.
The problem that people have with Hegel is that the Marxists use his ideal state as a justification for their failed socialist experiments. Might as well attack Plato for the same reasons. Or Leonard Nelson also! [But of all people, Hegel ought not to be used for justification for socialism. He was a capitalist.]
Because I have been influenced by Plotinus [the beginning of Neo Platonism], I tend to see all mentions of pure reason in Kant as being the Logos in the heavens. [The order is the One, who emanates Logos which brings forth Being.] And I do the same when I read Hegel. So I just do not see much conflict between Kant and Hegel. Just that they are addressing different issues.
