Liberal democracy has been experiencing a crisis of representation over the last decade, as a disconnect has emerged from some of the foundational principles of liberalism such as personal freedom and equality. In this article, I argue that in the third part of Kant’s Religion within the Boundaries of Mere Reason we can find resources to better understand and counteract this crisis of liberal democracy. Kant gives a powerful argument to include an invisible ethical community under a political community, and (...) this ethical community has to take the form of a church. Kant argues then that any political system, and so also liberal democracy, requires religion to ally citizens in a foundational way with the general principles of that system. This would commit liberal nations to having their foundational principles buoyed by religion. Towards the close of the essay, I attend to how this might impact on liberalism’s commitment to religious and ideological pluralism. (shrink)
