Roughly the Kant Fries school of Leonard Nelson https://www.friesian.com/nelson.htm"> makes the most sense to me, but not exactly because of an issue in Kant. I,e, Kant accepts Hume's critique of reason to some degree and does escape from it. I however have an issue thus: I think Hume was wrong from the start. Reason is not limited to figuring out contradictions based in definitions like: bachelors are not married. Why did Hume make this mistake? Because in his day, Euclid had authority almost equal to the Bible. And in Euclid, reason is to see when a result of a hypothesis contradicts one of the five starting axioms. Hume says over and over that that is the only function of reason, but with no proof. He assumes it. But that is an arbitrary limitation. Kant did break out of that prison, but limited reason to the realm of possible experience. That is true to some degree, but still assumes that there is no knowledge outside of reason or empirical experience. But that too is too limiting. For even if we start with Euclid, from where do the axioms come from? Why are they reasonable? That is the starting point of Fries and Leonard Nelson: non intuitive immediate knowledge I owe a debt of gratitude in understanding this to Kelley Ross for his web site on the approach of Leonard Nelson and in particular his PhD thesis there. Also To Michael Huemer in his books and essays and Brain Caplan and Steven Dutch whose web it is back after being down for year.
