Abstract
Kant's ethics demand suppositions where a noumenal freedom does not contradict natural causality. A rational faith in God makes this possible, through a progressive program in nature, including history, through strife, culminating in the doctrine that the republican form of government represents man's essential ethical essence. This captures many traditional religious views but Kant asserts them as a rational exposition in response to modern and contemporary intellectual currents, especially Hume, Rousseau and Herder
