There is a contradiction within Kant's thought where he stated that
revolution is never justified, yet he did express support of the actual French Revolution that occurred during his lifetime. Revolution is a disruption of a specific political order and an introduction of an external reality. However, Kant proposed that when the law is made to be universal then a revolution can not be a higher authority than the law. Revolution places the entire idea of a universal law into jeopardy in all cases. But the law always arises from specific individual ethics, so instead of a revolution there must be a reconnection between the universal and the particular.
