Abstract

I will first provide a brief outline of Iselin’s main work on the philosophy of history, focusing on these questions: What are the aims of universal history? What function does it have? Subsequently, I will examine the particular concept of humanity that is the subject of Iselin’s history. I argue that the subject of universal history is denoted by a kind of hybrid concept that connects morality qua human nature with humankind understood as the collective of all humans - this being Iselin’s most impressive and influential philosophical invention. Regarding the ‘constellation’ that Iselin is situated in, I will briefly argue that the book methodically sketches a unique approach to universal history within the German-speaking world, while making certain advantages and limitations in this project transparent and arguing that it is also the first book to introduce the term "humanity" ("Menschheit") in a prominent place, a term that was to play a central role in late German Enlightenment. I claim that this concept of humanity most likely had a significant impact on Kant’s and Herder’s conceptions of humanity, as a consequence of which some ideas found in both authors can be interpreted as implicit reactions against Iselin.
