 A self-imposed commitment to report on the progress of his research efforts to the Berlin Academy at regular intervals induced him to devise his own specific style of presentation that allowed him freely and creatively to combine elements of the philosophical essay with those of a scholarly exposition. Among the important of his academy addresses marking the progress and direction of his investigations belong his “On the Task of the Historian” (“Ueber die Aufgabe des Geschichtsschreibers”) of 1821 (GS Vol 4: 35–56); “On the Origin of Grammatical Forms and their Influence on the Development of Ideas” (“Ueber das Entstehen der grammatischen Formen und ihren Einfluss auf die Ideeentwicklung”) of 1822 (GS Vol 4: 285–313); “On Alphabetic Script and its Relation to the Structure of Language” (“Ueber die Buchstabenschrift und ihren Zusammenhang mit dem Sprachbau”) of 1824 (GS Vol 5: 107–133); “On the Grammatical Structure of the Chinese Language” (“Ueber den grammatischen Bau der Chinesischen Sprache”) of 1826 (GS Vol 5: 309–325); “On the Dual Form” (“Ueber den Dualis”) of 1827 (GS Vol 6: 4–30); “On the Languages of the South Sea Island” (“Ueber die Sprachen der Südseeinseln”) of 1828 (GS Vol 6: 37–51); and two presentations on the Indian Bhagavad-Gita poem (Ueber die Bhagavd-Gita) of 1826 (GS Vol 5: 158–89; 325–44). These and his other presentations formed part of the published proceedings of the Berlin Academy.
