This text examines Immanuel Kant's distinction between philosophers who draw directly from the sources of reason and those whose philosophy consists solely of the history of philosophy. The author explores the tension between original philosophical creation and the mere reporting of past achievements. While historians of philosophy wait for others to complete their work so they can report on what happened, true philosophers strive to execute something new that has not existed in such a form before. The reflection focuses on the question of where one can philosophically draw from to create novelty. The work reflects on the nature of the philosophical source and investigates the mission of a thinker who is not satisfied with mapping the past but seeks to be present at the very moment a philosophical event occurs. The central problem lies in identifying the essence of the matter at hand for philosophers and defining the boundary between the creative act of reason and historical documentation.
