I hold it that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms are in the physical. Unsuccessful rebellions, indeed, generally establish the encroachments on the rights of the people, which have produced them. An observation of this truth should render honest republican governors so mild in their punishment of rebellions, as not to discourage them too much. It is medicine necessary for the sound health of government.

Letter to James Madison, 1787
