 Wolff’s wide intellectual interests saw him exposed to a diverse set of influences. Neumann not only acquainted Wolff during his time at Gymansium with the Cartesian philosophy but impressed on him the need for “mathematical” treatments of philosophical topics (including natural theology and practical philosophy). Wolff also familiarized himself with late Scholastic philosophy, through a textbook by Johannes Scharf (1595–1660), a follower of Suarez; indeed, Wolff’s mastery of Scholastic thinking was displayed in his successful disputations with students at the rival (Catholic) St.-Elizabeth-Gymnasium. While Wolff’s own later philosophy would likewise be branded a form of scholasticism, or Schulphilosophie, the extent of the influence of Scholastic philosophers, such as Suarez, upon his thought is debated (École 2001, Leduc 2018). Wolff’s interest in mathematics was encouraged by his teachers, which interest ultimately brought him to Jena where he attended classes from G. A. Hamberger (1662–1716), the successor of Erhard Weigel (1625–99); he also studied a Euclidean textbook by J. C. Sturm (1635–1703), though his reflection on its obscurities reportedly brought him his “first light concerning the ancient method of demonstration” (Wuttke 1841: 122–3).
