This excerpt from the Declaration of Independence is describing the social contract.
Explanation:
The theory of the social contract has been developed since the seventeenth and eighteenth centuries through the works of Hobbes, Locke and Rousseau. The concept of a social contract implies that people partially renounce their sovereign rights in favor of the state in order to ensure their interests through it. A social contract means thereby an agreement reached by citizens on issues of rules and principles of public administration with the corresponding legal registration.
In accordance with the main principle of theories of social contract, a legitimate state body is formed on the basis of forced consent of the governed. The starting point for most of these theories is the study of the conditions of human existence that are absent in the so-called “natural state”, when people themselves follow personal gain. Proceeding from this initial position, supporters of the theory of the social contract explain differently why a rational person, following his personal interest, should voluntarily renounce the freedom that everyone has in a "natural" state.
