Schaeder’s immense talent allowed him to acquire a thorough knowledge of the languages, literatures, and history of the Middle East, especially Iran. Through independent studies he was able to apply this knowledge to research into the history of Oriental religions. In fact, for various problems of Manichaeism, he offered ground-breaking solutions (Iranische Beiträge, 1930; Iranica, 1934). Similarly, his great talent for synthesis produced some excellent results for Old Testament and Islamic studies as well (Esra der Schreiber, 1930; Hasan al-Basri, 1919–1924; Hafiz, 1922, etc.). His scientific research into literature (e.g. Goethes Erlebnis des Ostens, 1938) can only be mentioned as an aside here.

Schaeder was firmly rooted in European humanism; he not only witnessed its fatal crisis, but appears to have represented it himself and to have his scholarly activities confined by it as well. Indeed, the living Middle East of his time remained alien to him, something unknown and not very likable.
