Aristotle, 9.
The Lives and Opinions of Eminent Philosophers (c. 200 A.D.), Book 5: The Peripatetics

Inzwischen bleiben die solchermaaßen beschränkten Universitätsphilosophie bei der Sache ganz wohlgemuth; weil ihr eigentlicher Ernst darin liegt, mit Ehren ein redliches Auskommen für sich, nebst Weib und Kind, zu erwerben, auch ein gewisses Ansehn vor den Leuten zu genießen; hingegen das tiefbewegte Gemüth eines wirklichen Philosophen, dessen ganzer und großer Ernst im Aufsuchen eines Schlüssels zu unserm, so rätselhaften wie mißlichen Daseyn liegt, von ihnen zu den mythologischen Wesen gezählt wird; wenn nicht etwa» gar der damit Behaftete, sollte er ihnen je vorkommen, ihnen als von Monomanie besessen erscheint. Denn daß es mit der Philosophie so recht eigentlicher, bitterer Ernst seyn könne, läßt wohl, in der Regel, kein Mensch sich weniger träumen, als ein Docent derselben; gleichwie der ungläubigste Christ der Papst zu seyn pflegt. Daher gehört es denn auch zu den seltensten Fällen, daß ein wirklicher Philosoph zugleich ein Docent der Philosophie gewesen wäre.

The line is not found in Thucydides.
