This unit summary explores the foundational concepts of political philosophy, particularly focusing on the ideas of Natural Rights and the Social Contract as articulated by Thomas Jefferson. It delves into the Enlightenment principles that influenced the drafting of the Declaration of Independence in 1776, emphasizing the inherent rights that every individual possesses and the responsibilities of government in protecting those rights. The glossary defines key terms such as Natural Rights—rights that are inherent to each person—and Social Contract—the agreement among individuals to form a government that promises to safeguard their rights. The summary encourages students to connect Jefferson's famous assertion of 'Life, Liberty, and the pursuit of Happiness' to the governmental responsibility outlined in these foundational concepts.
