Julius Friedrich August Bahnsen (30 March 1830 – 7 December 1881) was a German philosopher. Bahnsen is usually considered the originator of characterology and a real-dialectical method of philosophical reflection which he laid down in his two-volume ''Contributions to Characterology'' (1867) and developed forth with his following works, amongst others his magnum opus ''The Contradiction in the Knowledge and Being of the World'' (1880/82).
