 Like all of his German contemporaries, Kant could not have avoided being affected by memory of the acrimonious conflict that had occurred between the Pietists and Christian Wolff (1679–1754) at the University of Halle just a generation prior. However, by the time Kant arrived at the Collegium Fridericianum, Pietism—particularly in Königsberg—had taken on a milder form, one which often sought to adopt but also revise the teachings of Wolff in accordance with Pietist principles (De Vleeschauwer 1962; Kuehn 2001). The most significant example of this is found in Kant’s influential teacher at the University of Königsberg, Martin Knutzen (1713–1751), whose Philosophical Proof of the Truth of the Christian Religion (1740) argues that the core of Christianity lies in “presenting us with a genuine means of atonement” (Knutzen 1740: §39) and that the necessary revelation of such a means can be rationally demonstrated using largely, but not exclusively, Wolffian principles.
