Methodological dualism defines the seemingly insurmountable bridge between “the external world of physical, chemical and physiological phenomena and the internal world of thought, feeling, valuation and purposeful action.” [Mises in Human Action, Fourth Revised Edition (San Francisco: Fox & Wilkes, 1996), p. 18] The cusp of social sciences is always near this enigma. The exploration of the human mind is the task at hand and it will be a task of primary importance for the foreseeable future.
Consider one evident manifestation of dualism: the act of rational self-interest that ultimately leads to the well-being of all. This is the very essence of the divine economy! As you can see the divine economy must be profound indeed!
