There is widespread agreement in scholarship that Moses Mendelssohn lacked historical thinking, an opinion accepted even among Mendelssohn experts. This misjudgment is based on a remark in his Jerusalem against Lessing’s Education of Humankind and surely ignores Mendelssohn’s historical work. I will question the misjudgment by a detour: first, I will ask for whom Lessing wrote his Education of Humankind. Then I will turn to the usually celebrated origin of historical thinking in Semler and Herder and question the historicity of (...) their views. It is only in the 3rd section that I will focus directly on Mendelssohn’s historical work and his truly historical understanding of religion, in agreement with Lessing. (shrink)
