Final answer:
Enlightenment thinkers believed in the existence of the natural rights of people.
Step-by-step explanation:
The Enlightenment was a philosophical movement in Europe during the 18th century that emphasized reason as the primary source of authority and advocated for ideals such as liberty, progress, tolerance, and constitutional government. Enlightenment thinkers, such as Thomas Hobbes, John Locke, and Baron de Montesquieu, believed in the existence of the natural rights of people. These natural rights included the rights to life, liberty, and property, and they proposed that individuals had the right to change the government if it failed to protect these rights.
