Abstract

Montesquieu believes that human beings have three kinds of natures: self-preserving, imperfect knowledge and passions. The first and the third nature tend to conflict with each other, and the result is the state of war, in which human natures could not be satisfied. Montesquieu uses this theory of human nature to judge all the kinds of governments, and finds that the virtuous republic, despotism and monarchy all have important defects. Especially, the monarchy by nature tends to degenerate into despotism, which is a realistic threat to him and his contemporaries. To solve this political problem, Montesquieu himself develops a two-fold solution: he wants to establish a certain kind of positive laws to satisfy the first nature, and wants to promote commerce to satisfy the third nature. Moreover, his ideal-government has important differences with the English political system.
