1. Enlightenment Thinkers

2. Thomas Hobbes
His most famous work was called Leviathan.

3. Thomas Hobbes
To escape the state of nature, people would enter into a social contract: they would give up some freedoms in return for the safety and order of an organized society.
Hobbes believed that a powerful government like an absolute monarchy was best for society – it would impose order and force obedience. It would also be able to suppress rebellion.
His biggest influence on government was being the first thinker to popularize the idea of social contract

4. John Locke
Locke wrote the “Two Treatises of Government”

5. John Locke
He believed we are born with natural rights: The right to life, liberty, and property. Rulers / governments have an obligation (responsibility), to protect the natural rights of the people it governs.
Locke believed in a social contract consisting of self government. The people rule (popular sovereignty).
If the government fails to protect the natural rights of the people, the people have the right and obligation to alter (change) or abolish (overthrow) the government and create a new contract.

6. Declaration of Independence Written by Thomas Jefferson 1776
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

7. Baron de Montesquieu
He wrote The Spirit of the Laws.

8. Baron de Montesquieu
In his version of a social contract he believed government could improve liberty by creating a safe country with laws.
Separation of Powers - the best way to protect the freedom of the people was to divide the powers of government into three branches:
Legislative: Makes the Law
Executive: Enforces the Law
Judicial: Interprets the Law
To help one branch not gain all the power Montesquieu established Checks and Balances
Each branch of government would check (limit) the power of the other two branches. Thus, power would be balanced (even) and no one branch would be too powerful.

9. Jean- Jacques Rousseau 1712-1778
His most famous work was The Social Contract.

10. Jean- Jacques Rousseau 1712-1778
For Rousseau, the social contract was the path to freedom: people should do what is best for their community.
The general will (of the people) should direct the state toward the common good. Government must follow majority rule, or more than half of people agreeing to a decision.
He believed in a direct democracy .
He influenced our founding fathers to include democracy in the Constitution.
