Pierre Hadot, "Dieu comme acte d'etre dans le neoplatonisme," in Dieu et L'Etre (Paris: Etudes Augustiniennes, 1978), 57-63, building upon the work of de Vogel, argues that the idea of God as infinite being and the pure act of existence from which all beings receive their existence is found in the Neoplatonic anonymous commentary on the Parmenides (which Hadot attributes to Porphyry) and was communicated to Aquinas through Boethius's Hebdomads . Wayne Hankey has continuously argued that Aquinas should be understood as continuing the Neoplatonic tradition conveyed to him by Dionysius and Erigena; see for instance, his "Aquinas's First Principle: Being or Unity"Dionysius 4 (1980): 133-73.
