On Callicott's Subjective Intrinsic Value

Applying the approach of the dichotomy of Descartes' distinction between subjects and objects,and Hume's ancillary distinction between fact and value,Callicott explored the metaphysics of quantum theory and ecology which is the base on which the axiology of intrinsic value is built. He confirmed his subjective intrinsic value theory systemically as well as animadverted objective intrinsic value theory to improve the intrinsic value theory from Kant.
