In Defense of “Extreme Apriorism”

All the positivist procedures are based on the physical sciences. It is physics that knows or can know its “facts” and can test its conclusions against these facts, while being completely ignorant of its ultimate assumptions. In the sciences of human action, on the other hand, it is impossible to test conclusions. There is no laboratory where facts can be isolated and controlled; the “facts” of human history are complex ones, resultants of many causes. These causes can only be isolated by theory, theory that is necessarily a priori to these historical (including statistical) facts.
