 Marty’s philosophical work is distinct especially as an application of Brentano’s descriptive psychology to the study of language in opposition to many of the prominent currents in linguistics and philosophy of language during his time. These were in many cases much more historical rather than psychological in character, but also often based on psychological theories wherein intentionality was not fully or hardly at all thematized as it was in Brentanian psychology. Marty’s philosophy of language is accordingly outstanding as a reflection on linguistic phenomena as essentially intentional.
