misuse of a philosophy

if every misuse of a philosophy can be attributed to that philosophy is doubtful. But there is a point to it when the empirical evidence is overwhelming. For Communism, Hegel was used by Marx to provide the intellectual backbone of communist economic theory but if that misuse can be attributed to Hegel is doubtful. I rather would like to see that Kant saw an important limitation of reason. It cannot go into the dinge an sich. Things in themselves. That idea flows from John Locke who saw a difference between primary characteristics of things that belong to the things in themselves and secondary characteristics that in part come from the observer. Kant held that all characteristics in part come from the observer. Even essential things like color still need to be observed Thus, if you disregard all secondary and primary characteristics, what is left?-The thing in itself. Rav Nahman also noticed the limit of even pure reason. However, Hegel did notice that reason progress. It is not stuck in what it used to know, but can even progress to what is not yet known. But that does not mean that there is always some limit. Just that the limit itself in not steady. It can go forwards or backwards. [My opinion is that philosophy would benefit with a return to Kant, Fries, Hegel, Leonard Nelson, Kelley Ross ; and ignore all subsequent twentieth century pseudo philosophies.] There is an implied philosophy in Musar. In particular the Chovot Levavot, however there is value in understanding metaphysics and physics in themselves as was the opinion of the Rambam. The Gra held slightly differently and held that one need to learn the organum of Aristotle known by the name of the seven wisdoms.It is odd that this opinion of the Gra and Rambam afre ignored.
