This dissertation is dedicated to Johann Gustav Droysen’s suggestion to install the discipline of History on ethics. Therefore we shall concentrate on his theoretical work, Historik. Firstly, we will consider the wilder context of German XIXth century historical thought, secondly the Kantian philosophy as the foundation of Droysen’s Historik (von Humboldt being the link between them, as Droysen noted himself), and thirdly the Aristotelian ethics with which Droysen maintains a vivid dialogue. By examining these topics, we will establish the fundamental elements of Droysen’s ethics – the particular be I (Ichsein), the general Humankind I (Ich der Menschheit) and the acts of will (Willensakte) - and their singular relations with historical experience and thought. Finally, we will raise the question whether Droysen did design a modern political philosophy by delimitating the cosmos of the ethical-historical world. As a conclusion we will present Droysen’s Historik as a modern (historicist) ethics.
