Enlightenment, state, and sovereignty: Kant’s political philosophy

In Kant scholarship, there has long been a debate about the connection between his political and ethical thought. In his works concerned with political theory, such as the Metaphysics of Morals, Perpetual Peace, or An Answer to the Question: What is Enlightenment?, he concerns himself with coercively enforceable principles by which a society can be organised. In his works on ethics, such as The Groundwork to a Metaphysics of Morals, or The Critique of Practical Reason, he is concerned with principles of morality, which require free and unconstrained action. Prima facie, the realms of politics and ethics in Kant’s thought thus appear to be incompatible. This thesis will close the gap between Kant’s ethics and politics through an examination of his anthropological works. The thesis will argue that Kant’s philosophical understanding of human nature, i.e. his “philosophical” anthropology, necessitates a connection between his ethics and politics. The project begins with a reading of Kant’s anthropological texts to show that his concern with human nature was directly related to politics and to ethics. This will allow the thesis to then discuss the way in which human nature necessitates politics as a condition of possibility for ethical deliberation to occur. Finally, having shown the necessity of politics for ethics, and thus their necessary connection, the thesis will present an overview of Kant’s political philosophy in light of this connection to show precisely the way in which politics supports rational ethical deliberation. These considerations will allow for the debate about the connection between Kant’s politics and ethics to be settled, and provide us with an understanding of the depth of Kant’s concern with human nature.
