the only philosophers that got support from any world class mathematicians were Jacob Fries and Leonard Nelson. That was the famous Nelson Affair file that David Hilbert kept in his office.

The school of Kantian thought of Leonard Nelson was well known in the U.S.S.R., but almost completely ignored in the West. [It is an odd fact that the only philosophers that got support from any world class mathematicians were Jacob Fries and Leonard Nelson. That was the famous Nelson Affair file that David Hilbert kept in his office. An besides that we know Gauss was impressed with Fries, and praised a book of Fries to a student that asked about it. [I might mention that the correspondence of Godel indicates a kind of two tier structure of the world like the Neo Platonic school. To me it seems very close to Nelson.[There are people who simply ignore the whole thing and want to go back to Aquinas like Ed Feser. The idea of finding in Medieval scholastic philosophers all the answers is perhaps a good point , but perhaps that all truth. There is something amazing about medieval thought. I have no idea what to say about that though.]Also all of this just refers to philosophy. They all had something to say about politics but that does not seem to be where their insights were very great. On the Contrary--it was English thought [John Locke, DeFoe, James Madison] that seemed to reach the greatest heights when it comes to political thought.
