7 pillars of wisdom
My classification of disciplines according to the viewpoints used by them:
I discern 7 different viewpoints used by 7 primary disciplines to convey a worldview, a “weltanschauung”. Because of using different viewpoints, every discipline has its own different method of understanding with a limited perspective and a defined scope of the investigation reserved for them. That is why I classify disciplines according their special viewpoints, i.e., which perspective and method should be used by a discipline to clarify and define its subject, and as a result, what could be the distinct character and meaning of that discipline, and its special “weltanschauung”.
