8. Thomas Aquinas: Postmodern
Barron (p265)
Habermas: the two tyrannies, modernity and the supreme being; post modernity and the supreme ego; from Descartes (Feuerbach) to Sartre's aphorism that we cannot be fully free as long as God exists; the supreme ego in Descartes, Hegel's self-conscious subject; but the new supreme being is hardly an improvement on the old one (p265); Aquinas is postmodern.
Thomas and the supreme being: Aquinas does not envisage a God in competition with 'his' creation: esse ipsum subsistens (p266); everything has a cause and the ultimate cause is God (p267); the to-be is not a general cause but a personal one (p268); God cannot be contained in a genus; esse is analogical (p269); there is no common reference to no competition; Anselm: id quomaius cogitari nequit; (p270). Duns Scotus: God and creation are in the same ontological and linguistic category: "God is understood only in the category of being", so God and creatures "compete", the supreme being has replaced ipsum esse subsistens. Suarez: metaphysics is being as being, prior to the nature of God (p271). Descartes misconstrued Thomas's analogy; thus the succession: Feuerbach, Marx, Freud, Sartre and the more nuanced onto-theology of Heidegger; they miss that Aquinas was as suspicious of the "supreme being" as they.
Aquinas does not subscribe to the postmodern view that the less we give to God the more we give to humanity: the non-being of God corresponds to the non-being of the creature (p272). Aquinas special case of ex nihilo locates creation as totally non violent; that which receives being is the being that it receives; that into which the gift of being goes is itself a gift of being. He inverts Aristotle's view that substance is fundamental and relationship incidental (p274-6). the Incarnation is the metaphysical paradigm of creation (p277).
