Abstract This paper offers an assessment of some of the central aspects of Edith Stein’s conception of intentional acts proposed in Potency and Act. Studies Towards a Philosophy of Being. Her account hinges upon a combination of Thomistic and Husserlian concepts. She borrows from Aquinas two conceptual pairs that are central to his metaphysics and theory of knowledge: the actuality-potency dichotomy; and the distinction between sensible and intelligible species. The distinction and relevant articulation between sensible and intelligible species provide Stein with the basis to present her own conception of intentionality (with special focus on perception): the sensible species is regarded as the correlate of the object’s Gestalt; by contrast, the intelligible species is mobilised to account for what Husserl labels noesis-noema correlation. But Stein’s ambition is also to inscribe her account of the species sensibilis within an overall (critical) interpretation of Husserl’s transcendental idealism.
