The epistemology of intentionality notional constituents vs. direct grasp

Franz Brentano is well known for highlighting the importance of intentionality, but he said curiously little about nature intentionality. According to Mark Textor, there a deep reason this: took intentionality be conceptual primitive which revealed only in direct grasp. Although certainly textual support this interpretation, it appears tension with Brentano's repeated attempts analyze terms ‘notional constituents’ – aspects cannot come apart reality can conceptually distinguished. After bringing out tension, I explore some options resolving it, ultimately offering my own favored interpretation.
