Jefferson's famous saying of learning mathematics
We hold the following truth to be self-evident: all men are created equal, and the creator endowed them with certain inalienable rights, including the right to life, liberty and the pursuit of happiness. In order to protect these rights, human beings established a government in it, and the legitimate power of the government was granted by the rulers. Once any form of government undermines the realization of these goals, the people have the right to replace or abolish it in order to establish a new government. The principles on which the new government is based and the way it organizes power must make people think that only in this way can they be most likely to achieve security and happiness. If we really want to be cautious, the government that has been established for many years should not be replaced for irrelevant and temporary reasons. All past experience shows that human beings are willing to endure any suffering as long as it is tolerable, and do not want to abolish the form of government to which they have long been accustomed in order to rehabilitate grievances. However, when a series of abuse of power and extortion that always pursue the same goal show that the government is trying to put the people under tyranny, the people have the right and obligation to overthrow such a government and provide new guarantees for its future security.
