Aquinas: Essence and Existence

Boethius identifies God both with esse ipsum and esse suum. This paper explains Boethius's general semantic use of "esse" and the application of this use to God. It questions the helpfulness of attributing to Boethius "existence" words and argues for a more robust role in Boethius’s thought for Hilary of Poitiers’s and Augustine’s exegeses of Exodus 3:14-15 than has been acknowledged in recent scholarship.

In this paper, we would like to share a view of Thomas Aquinas’ metaphysics which differs significantly from the “doxa of the act of being” currently widespread among Thomistic philosophers. -/- Nous voudrions faire part ici d’une vision de la métaphysique de Thomas d’Aquin qui diverge sensiblement de la “doxa de l’acte d’être” actuellement répandue parmi les philosophes thomistes.

What is the distinction between understanding and forming a concept? In my view, for Aquinas, intelligere (the act of understanding) and dicere (the forming of a verbum or mental word) are not two different acts, but simply two different aspects of the same act of understanding. In the following, I will explore more in depth what this distinction means for Aquinas. Firstly, I will give a mostly doctrinal or systematic overview of the issue and, secondly, I will support my claims (...) with relevant textual evidence, taken exclusively from Aquinas’ Summa Theologiae. This study, as an appendix, is part of “The Influence of Kant in Transcendental Thomism: Rahner, Lonergan and Von Balthasar” (forthcoming). In my view, Lonergan’s way of distinguishing intelligere and dicere is different from St. Thomas’ way. In the body of my book, I focus on Lonergan’s reasons to distinguish these notions in his own particular way, whereas this study focuses on St. Thomas’ doctrine. It is my hope that the following lines will foster an understanding of St. Thomas’ epistemology and of its application to Trinitarian theology. (shrink)
