2. The Enlightenment
Scholars began to challenge long held beliefs about science, religion, and government
Thinkers were inspired by Galileo and Newton.

3. The Enlightenment
In France, thinkers called philosophes (or “philosophers”) would gather in informal meetings called salons.
There, they would exchange and debate ideas.

4. The Basic Questions
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.
Others argued that the people should have a say in their own government.
They all shared a trust in reason and observation as the best way of understanding and progress.

The true basis of government was a social contract (or agreement), among free people.
His theory is that a governments authority is based on the consent of the people. If the government fails to respect people’s rights, it can be overthrown.

11. Baron de Montesquieu
His Observation: Too much power in the hands of any one person or group will lead to tyranny.
French author, in 1748, he published The Spirit of Laws.
He argued that the best way to protect human rights is to divide power among three branches of government.
Each branch of government checks (limits) the power of the others.
Separation of Powers

Executive branch – enforces the laws
Judicial branch – interprets the laws

of the crime.
