Die ooit de the Schliemann of the esoteric Plato is genoemd door Vittorio Hösle

Men spreekt nu ook wel van de 'Tübingen school'. Dat maakt het volgende ironische citaat van David Sider (Bryn Mawr Classical Review) begrijpelijk: Plato von Tübingen is of course the well known author of Ungeschriebene Lehre, a best seller in Germany which has received some attention in France and Italy, but which has not been well received by il mondo anglosassone, where Plato is taken straight and unmediated by later writers such as Aristotle, Aristoxenos, Gaiser, and Krämer.
