How Kant was Never a Wolffian, or Estimating Forces to Enforce Influxus Physicus
This chapter aims to show that Kant has never been a Wolffian but started his career precisely from the core problem of the Pietists to secure the influxus physicus and thereby liberum arbitrium. I will first present the battle of Pietist and other Lutheran theologians against Wolffianism as a theological-political battle, which explains its extension as well as its fierceness. Then I will explain how a metaphysical hypothesis such as Leibniz’s pre-established harmony could become the subject of a theological-political debate in the Protestant area of the Empire lasting for decades. Only in the third section I will situate Kant’s very first, but quite lengthy book in this context and contrast his declared intention to solve the controversy between Leibnizians and Cartesians about the estimation of forces with his actual metaphysical approach to save influxus physicus. It will be shown that Kant’s approach lacks any familiarity with modern mechanics and mathematics. Finally, I will point to the contemporary reception of Kant’s first book which confirms my evaluation.
