Rav Nahman was very much against learning philosophy and that approach is very much like that of some mediaeval authorities (e.g. Ramban/Nachmanidess).  But this is clearly an argument among the Rishonim. So I have at least some opinion to depend on.

Thus I would like to bring Kant in support of faith. I mean that questions on faith often come up and the answers are not satisfying. To this I answer the when one ventures into the realm of dinge an sich, contradictions arise automatically. what are things in themselves? They are both things stripped of all characteristics supplied by human minds, and starting axioms of reason. and furthermore Kant adds that this applies not just to abstract reason but also to individuals and societies

I see great importance of this approach of Kant and in particular in the Kant Fries school of thought. but i do not share the distain for Hegel that seems to permeate all neo Kantian schools.

Hegel thought that by the dialectic, it is possible to get beyond the limitations of pure reason and empirical reasoning. He did not deny the problem of the ''thing in itself,'' but rather thought that this process, it is possible to get beyond it

I would like here to take an opportunity to recommend a particular modification of Kant by Jacob Fries and Leonard Nelson that I think is the best approach in Philosophy even though this also needs a bit of tweaking the variables because the absolute position of Newtonian space and time can not be the fundamental starting place of all possible human reasoning. While Leonard Nelson was right that you have to have starting axioms without which Reason can not start, but Newton's space and time are not them. rather you have to start with Maxwell's equations of electro magnetism and the speed of light being constant.     [If only nelson had realized this in time, the whole Friesian school might have fared better, --in particular Bernays saw right away that the Friesian school needed to deal with Einstein in a more constructive way. IF anyone has the time i highly recommend the phd thesis of dr kelly ross on the friesian approach.
