Answer;
Enlightenment
Explanation;
-The Declaration of Independence draws heavily on the ideas of Enlightenment thinkers such as John Locke. Much of what Jefferson wrote in the Declaration comes direct from Locke's ideas about government.
-The Declaration of Independence says that people have certain rights just because they are people.These rights are not given to them by the government and cannot be taken away from them.They have these rights simply because they are human. This is a major idea of the Enlightenment.
-Social contract theory is the view that persons' moral and/or political obligations are dependent upon a contract or agreement among them to form the society in which they live.
