Final answer:
Enlightenment thinkers despised the current systems of government due to their opposition to absolute monarchy and their belief in the protection of natural rights. Their ideas influenced revolutions such as the French and American Revolutions.
Step-by-step explanation:
The Enlightenment brought a clash of ideas with new beliefs on constitutional monarchies or republics, causing Enlightenment thinkers to despise the current systems of government during the 1600s-1700s. The writings of Locke, Voltaire, and Rousseau contradicted the centuries-old traditions of the political-social order. They asserted theories that the people had a right to change the government if their natural rights were not protected. These ideas spread across Europe and influenced revolutions such as the French Revolution and the American Revolution.
