Abstract

Phenomenologist Dietrich von Hildebrand argues that many properties of the material world only exist in relation to persons, that sense perception is not merely a bodily act, but a properly spiritual, personal act, and that our highest act is not purely intellectual but involves bodily sense perception. By his own assertion, his philosophy must be understood in the context of the Catholic philosophical tradition; here, I consider his account of the material world and of sense perception in comparison to two strands of the Aristotelian tradition in Catholic philosophy, represented by Thomas Aquinas and Gregory Palamas. I show how von Hildebrand’s views on the material world and sense perception can be better understood, their phenomenological bases defended, and their deficiencies corrected, by drawing on the notion of energeiai from Palamas’ thought, and of participation and obediential potency from Aquinas’ thought.
