The document discusses the views of Montesquieu and John Locke on the legitimacy, consent, separation of powers, and individual liberty of government. Montesquieu believed that laws were natural and there were three types: law of nations, political laws, and civil law. Both philosophers agreed that government should be derived from the consent of the people and protect individual rights and freedoms. Montesquieu advocated for the separation of government powers into legislative, executive, and judicial branches to prevent the concentration of power, an idea also supported by Locke. Additionally, they both felt that individual liberty should be ensured and only restricted by laws concerning public order and security.
