Enlightenment thinkers wanted to learn more about human life using these questions:
What natural law governs the way people should live?
How well do our institutions agree with natural law?
Does natural law give all people certain rights?
What is the best form of government?

5. Philosophers
Philosophers did not always agree about the answers to these questions.
Some supported absolute rule by the king.
