I also do something akin to what Mises did in grounding transcendental idealism in objective, empirical reality via the various compenents of human action.

When I was younger, I formulated something approximating Kant's entire philosophy on my own. As I learned more about the mature of objective reality however, and human interaction, I discovered I didn't need to carry the weight of the world on my shoulders as Kant's morality would tend to imply. Man's happiness is effected by Nature and by God moreso than any servile attitude toward other people's needs.

I must admit that a lot of his work is kindof hard for me to grasp and because I never read it in my native language, it's non-ideal.

I'm quite sure that a lot things got blurred in translation. I don't know if you speak german, but it might be a different story.
