Abstract
Do the modalities of expressing what is, as laid out by Brentano in his On the Manifold Sense of Being according to Aristotle, represent an analysis of the form of what is (Seiendes) as such, or perhaps even of the forms of thought by which we grasp what is? Or is it, rather, an analysis of being (Sein) as manifested in what is? Brentano’s Die Psychologie des Aristoteles, especially his exegesis of the nous poietikos and his paradigmatic analysis of the subsumption of sense-qualities under their idia and of rational knowledge as knowledge of the eide, demonstrates that for Brentano, Aristotle is a philosopher of the manifestation of being in what is.
