After the War of Independence, with the development of class struggle, especially after the failure of Xiasi Uprising, Jefferson not only defended this idea, but also enthusiastically praised the revolution. He wrote: "Let them take up arms! ..... What does it matter how many lives are lost in a century or two? The tree of freedom must be watered with the blood of patriots and tyrants. It is the natural fertilizer of the tree of freedom. " He also wrote ... we really provided the world with a beautiful example of reforming the government only by reason without bloodshed, and we are proud of it. But the world is too oppressed to benefit from this example. "
