During high school this moderation was not felt. The instructors at the Collegium were stern. Pietist schooling involved a rigorous schedule, strict adherence to religious dogma, and instruction by repetitive drills. The school’s goals were two-fold, to save it’s pupils from “religious corruption” and to improve their “worldly well-being” (Kuehn 2001a: 46). Strict adherence to regimen, dogma and practical applications were essential to these two goals. A former classmate, David Ruhnken, criticized the “discipline of the fanatics” (letter to Kant 10 Mar. 1771; 10:117.15); another classmate and life-long friend, Theodor Hippel (1741–96), spoke of Kant’s “terror and fear” whenever Kant would later recall the “slavery of his youth” (Malter 1992: 95; tr. Kuehn 2001a: 45).
