In 1953, Milton Friedman wrote out what have been the guiding principles of modern, orthodox economics that were necessary should it wish to join the ranks of serious science. In his Methodology of Positive Economics, Friedman recognized economics unlike harder sciences proceeds from an enormous disadvantage, meaning that for the most part all of it is unobservable. We know that an economy happens and that there are observable conditions that relate to the immense and complicated interactions that make up any economic system, but to figure out exactly how A becomes B is all but impossible. You and I may arrive at the same place, economically or financially speaking, but the way in which we did might be extremely different and that might be important.
