Platon et Aristote ont-ils pratiqué l'histoire de la philosophie?

Abstract Most histories of philosophy make us believe, that there is a line of thought from the Greeks on until today. This impression should be checked by this article. At first we contrast some pros and cons of the view that philosophy in general has a history. Then we come back to the question, if Plato or / and Aristotle are really the founders of historiography in philosophy. As test-piece we take the passage in the centre of Plato's Sophist, which shows that the references to past thinkers don't have the purpose to inform us historically, but, first, to continue the current dialogue about being, second, to lead us to the aporie about being, which allows a fresh start for this question. A glance at the doxographies of Aristotle shows (we have a look at that of De Anima), that they have the same target in view, namely to reveal the fundamental opinions of being in a respective world. This way the “history of philosophy” becomes an account of succeeding worlds and the related reflection on it. – This article is an extended version of a short lecture held in Geneva, 15. sept. 2016, within the scope of the Symposium of the Schweizerische Philosophische Gesellschaft.
