In his recent State of the Union address, President Donald Trump paid tribute to Thomas Jefferson, the author of the Declaration of Independence, who died on July 4, 1826. While Jefferson was a complex historical figure with flaws, his radical ideas about natural rights and the purpose of government, rooted in ancient Greek philosophy, laid the foundation for the American Revolution and continue to influence the country today.

Why it matters

Thomas Jefferson is one of the most important and influential Founding Fathers, whose vision of natural rights and limited government has had a lasting impact on American democracy. Despite his own contradictions as a slaveholder, Jefferson's ideas about the inherent rights of all people and the role of the state to protect those rights have become cornerstones of the American political system.

The details

Jefferson was deeply influenced by the ideas of ancient Greek philosophers, particularly Epicurus, who believed that the goal of life was to attain personal peace and tranquility by limiting one's desires. These Enlightenment principles of natural law and natural rights formed the basis of the Declaration of Independence, which Jefferson drafted. The American Revolution was rooted in these radical notions of individual liberty and the consent of the governed, which traced back to the political thought of ancient Athens.
