Abstract

The reflections of Jean-Luc Marion on Aquinas’s notion of esse not only confirm the continued importance of the latter’s doctrines in the history of metaphysical speculation, but also reveal intriguing convergences of concern between Aquinas and this significant postmodern thinker. Marion’s embrace of phenomenological reflection tinted with Barthean and Heideggerian themes in order to retrieve Neoplatonic ‘theo-ontology’ ironically finds unsuspected corroborations along with important clarifications in Aquinas’s subtle assimilation of Neoplatonic sources and his rigorous causal analyses of the metaphysical constitution of things and knowledge.
