A compilation of monographs on the subjects of unification in modeling (1) physical phenomena and (2) domestic & global economic structure in stocks and flows, both from a phenomenological perspective which is intended to be both quantitatively and qualitatively rigorous. When the phenomenological perspective is understood to be necessarily historical, the introductory monograph can be understood as unifying in the development of these two schools of thought. When that perspective is understood to be necessarily subjectively human, the unification becomes complete with an understanding of the essential nature of the human soul.
