  Phenomenology was already linked with logical and semantic theory in Husserl’s Logical Investigations. Analytic phenomenology picks up on that connection. In particular, Dagfinn Føllesdal and J.  N. Mohanty have explored historical and conceptual relations between Husserl’s phenomenology and Frege’s logical semantics (in Frege’s “On Sense and Reference”, 1892). For Frege, an expression refers to an object by way of a sense: thus, two expressions (say, “the morning star” and “the evening star”) may refer to the same object (Venus) but express different senses with different manners of presentation. For Husserl, similarly, an experience (or act of consciousness) intends or refers to an object by way of a noema or noematic sense: thus, two experiences may refer to the same object but have different noematic senses involving different ways of presenting the object (for example, in seeing the same object from different sides). Indeed, for Husserl, the theory of intentionality is a generalization of the theory of linguistic reference: as linguistic reference is mediated by sense, so intentional reference is mediated by noematic sense.
