Archephysics, Water, Gracefulness

Aristotle's study of First Principles has more in common with what might be called the 'Archephysics' of the pre-Socratics, starting with Thales, than with the 'Metaphysics'--a term that he himself does not use--of the Dualists who appropriate his doctrine for Theological purposes.  Now, 2500 years later, Thales' thesis that the fundamental stratum of existence is Water might seem quaint, and certainly seems inadequate to explain the existence of Fire.  Still, that the earliest phase of human life occurs in amniotic fluid, and that the human body is 60% water, indicate that his proposition is not entirely without merit.  It also suggests that the wide appreciation of fluidity of motion, i. e. gracefulness, has a deeper organic origin than what is connoted by the common classification of it as an 'Aesthetic' pleasure, i. e. enjoyed by the external senses.
