The extent to which the philosophy of Immanuel Kant converges with or diverges from Christian thought has been a hotly debated topic in recent years. Central to that debate has been the resurgence of interest in Kant's classic Religion within the Boundaries of Mere Reason (henceforth, Religion). The most insightful interpretations and applications of Religion, it seems, have utilized resources from a broad range of Kant's writings, emphasizing his philosophy considered as an integrated whole. Christopher Insole's recent monograph—Kant and the Divine: From Contemplation to Moral Law—attempts to redirect this debate with an argument spanning Kant's precritical and critical periods in performing a deep dive on the topic of freedom. On the face of it, the argument is not purely theological or even religious. It revolves, instead, around a metaphysical analysis of freedom, both as exemplified in Kant's writings and relative to his historical predecessors. Key to Insole's proposal is that Kant's critical notion of freedom evolves into something very different than that of his predecessors (on which his early writings depend) and, in its development, decisively "ruptures" with the Christian tradition. Human freedom, on Insole's analysis of Kant, must be "end-setting" and not constrained or directed by any type of external compulsion. This suggests that God cannot be understood to influence freedom causally, or at least not without human conscious and free consent. Numerous writers have thought they spied Christian connections in Kant's notion of freedom, such as the need for divine forgiveness, and even grace, to avoid the absurdum practicum. Insole resists all such attempts as being foreign to the novelty of the mature Kant's reflections on freedom. No external force can be brought to bear as a determining causal influence on human freedom, presumably because an end set before us from outside undermines our ability to set an end for ourselves. God is at best the "all-knowing distributor of happiness" (321) that makes end-setting and the kingdom of ends worthwhile moral pursuits. Insole's express intention is to "show the significance of Kant's denial that God can be our final cause" and that "his philosophical religiosity, understood on its own terms, and as expressed across his whole oeuvre" shows that "Kant cannot easily be called a Christian thinker" at all (2–4). Extricating Kant from Christianity proves to be a monumental task. Insole uses eighteen chapters and more than four hundred pages to make his case. The argument distinguishes itself from other such attempts in its rigorous analytic approach to unpacking the metaphysical underpinnings of issues supposedly at the root of Kant's philosophical theology. The book presents a cumulative case argument for Kant's supposed break with "the Christian theological tradition as he would have received it" (13). Much rests on whether or not this argument is cogent. Kant, according to Insole, is something akin to a theological Platonist and moral Stoic, who attempts to establish a unique form of "philosophical religiosity" (3 and 156). This makes Kant similar to the likes of Augustine and Ambrose, but different in terms of his theological aspirations. Insole casts Kant not as a pure philosopher seeking to understand philosophy relative to the Christian tradition, but rather as a philosophical [End Page 164] theologian bent on showing human freedom, free end-setting, and an ethical community of end-setters to be the exclusive means for attaining the highest good. Although this may sound Pelagian, Insole insists it is not, because "the Pelagian could still regard God as our final cause and efficient cause" (299). In other words, in Insole's interpretation, Kant is a strict philosophical humanist or what theologians might term a hyper-Pelagian. The difficult details of Insole's arguments are important to consider but not easily dealt with in the space provided here. Early in the book, Insole takes his reader on a metaphysical tour of "Divine Ideas" and "God...
