Abstract
Based on Kant’s own concept of politics, it is possible to construct his political philosophy that is related to but also different from his metaphysics of right. Politics is the practice of realizing the principles of right in experience; therefore, Kant’s political philosophy must explore the general conditions that make this practice possible. These conditions, such as political judgement, publicity and the enlightenment of the people, are indispensable to Kant’s thinking about human external freedom but do not belong to the metaphysics of right. Kant’s metaphysics of right is undoubtedly a liberal theory, but we can also identify some republican elements in his political philosophy. In this way, Kant provides us with a very instructive programme to absorb republican elements within a liberal theory.
