Thank you. I must be totally off understanding the ideas of pure and practical mind.
What is the name of Kant's concept of having a priori reason which enables one to know what is the right thing to do?
I found this little gem online (it's linked to marxists.org page, which does NOT include these words, go figure): "Critique of Pure Reason.
Immanuel Kant's major work in which he argues that we can have a priori knowledge of things in themselves but these things in themsleves can never be manifest in appearance which is known to experience."
I am not sure how this measures up to your "Kant's ideas were a critique of "pure reason". i.e. the impossibility of "knowing" the external world directly." The marxist.org explanation makes sense to me.
What could be an example? Maybe "awareness"? You know what it is, but you could not point at it, or put it on a shelf.
Could it be the same with "right action"? You know what it is, but you can't define it as a separate entity which can be revisited for later inspection?
