The New Friesian school of Leonard Nelson [https://www.friesian.com] needs some clarity in the writings of the frieian.com of Kelley Ross. One major point of clarity that Dr. Ross brings to the subject is that non intuitive immediate knowledge is not infallible. [It can need modification in view of new evidence. --evidence that has stronger prima facia likelihood].
This clarity would have avoided the seeming problem of Special Relativity. [And that is what caused the defection from the group of nelson to the Berlin group of Reichenbach.]
[Another important aspect of Kelley Ross is that he joins Fries with Schopenhauer.]]
You might think that this ought to be obvious but even in Germany where there is renewed interest in Kant, they go off on a tangent with Hermann Cohen and the neo-Kantian which is another dead end.
