Abstract

For the first time, documental evidence is provided in German to support the claim that during his Bern period Hegel continued to cultivate his interests and training in mathematics, physics and the natural sciences, thus filling an important lacuna in the development of Hegel's thought, also for the multifarious fund representative of both French Cartesian school and Newtonian handbooks present in Tschugg's library. So far, indeed, the Geometrische Studien and the 1801 De orbitis had been viewed as a sudden return to previous concern, after the Bern's gap. Moreover, according to the received view, the sources of Hegel's Dissertation dated back to the Frankfurt period.
