It explains that the Declaration of Independence established America's natural rights like life, liberty and the pursuit of happiness based on Enlightenment thinkers like John Locke.

The First Amendment protects freedoms of speech and religion based on Voltaire's ideas, and the Second Amendment addresses the right to bear arms but leaves its meaning debated.
