After summarizing the content of Philip Rossi’s book, The Ethical Commonwealth in History: Peace-Making as the Moral Vocation of Humanity, I pose two main questions. First, does politics or religion play a more important role in Kant’s philosophy when it comes to the task of ushering humanity to the realization of its ultimate vocation, the establishment of a lasting peace for human society? I argue that Kant portrays politics as a means to a religious end, whereas Rossi tends to reverse (...) their Kantian order of priority. Second, what concrete details does Kant give in defense of his theory that establishing an ethical community is a universal duty of humankind? As Rossi tends to overlook Kant’s details, I provide an overview. Kant argues that the ethical community can only be established in the form of a church and that the rational content constituting the core of the true church consists of four requirements: universality, integrity, freedom, and unchangeableness. After challenging Rossi’s claim that Kantian hope is necessarily social, I conclude with two minor questions: Is Kant’s theory of human nature dualist or monist? and Must the church create a political form of peace that applies to all human beings?
