In his new book, Rossi emphasizes the prominent role of enlightened religion in the political project of establishing perpetual peace. My paper discusses Rossi’s stance on the question as to whether Kant, in his later years, moved to an immanentist conception of the highest good. Kant’s own position in this regard can arguably be better described as comprehensive, according to which an immanent and a transcendent conception of the highest good are upheld as realizable side by side. Rossi’s account looks (...) perfectly consistent with such a view. One of the reasons for such a comprehensive reading is that “immanent” and “secular” do not coincide in Kant in the first place. Seen in this comprehensive way, and while a version of the highest good ought to be realized immanently, we cannot be certain that this will indeed happen. If it does indeed happen, the immortality postulate, which Kant never abandoned, renders it rational to believe that the immanent version of the highest good is merely a step towards its transcendent realization. Affinities of Rossi’s approach to the suggestion that Kant subscribes to a political theology based on what has been called “Molinism minimally defined” will also be explored. (shrink)
