The issue of causality is one of the most key and complex issues in Kant's philosophy, and has been the subject of much debate. However, most of this debate, like most other debates in Kantian philosophy, has focused on Kant's critical period. Part of the theoretical difficulties and complexities of the question of causality in Kant's critical philosophy, which have led to serious disagreements, is because Kant had discussed many of the basic issues of this topic in his pre-critical writings and therefore, in the critical period, he only addressed the theoretical implications of this topic. Therefore, the present article seeks to simplify some of these theoretical difficulties and complexities by examining the issue of causality in Kant's pre-critical texts and by analyzing the philosophical atmosphere surrounding the young Kant, which was particularly marked by the dominance of Leibnizian-Wolffian rationalists and Naturalists.
