The Abhandlungen [published journal] of the new Friesian school was quite critical of the Special Theory of Relativity. However it was pointed out by Kelley Ross that that rejection of Relativity did not flow or come automatically from Friesian principle as you can see in Dr. Ross's web site.
[The reason of Dr. Ross is that non intuitive immediate knowledge is not infallible. Rather that it can be modified because of empirical findings. And that synthetic a priori knowledge has to flow from starting axioms and not be self contradictory.
[I can see why the Friesians were alarmed by Relativity because to Kant all reason has to start with space and time--the categories.]
This is close to Michael Huemer's idea that what is known by reason is not necessarily infallible, but can and must be modified by new information. [This is his approach by means of probability (of Bayes)]. And it is not too far from Hegel either in which the door to the real reality can be opened by means of the dialectical approach of Socrates. But that dialectic in Socrates was not meant to be the only way in. [though it i possible that for Hegel, only the dialectical method an open the door to real reality, but i am not sure . concrete abstract synthesis might be almost by definition contain an element of empirical ''concrete''evidence]
