"

Prussian crown prince Frederick defended Wolff against Joachim Lange and ordered the Berlin minister Jean Deschamps, a former pupil of Wolff, to translate Vernünftige Gedanken von Gott, der Welt und der Seele des Menschen, auch allen Dingen überhaupt into French.[9] Frederick proposed to send a copy of Logique ou réflexions sur les forces de l'entendement humain to Voltaire in his first letter to the philosopher from 8 August 1736. In 1737, Wolff's Metafysica was translated into French by Ulrich Friedrich von Suhm (1691–1740).[10] Voltaire got the impression Frederick had translated the book himself.[citation needed]
