Voltaire has a distinguished place in the world because he was a
great symbol in the age of Enlightenment. A very prolific writer,
Voltaire achieved fame for his polemic satires and acerbic wit
(although he originally wanted to be a tragedian). He publicly
argued for freedom of faith and expression, the separation of
church and state, and wrote formidable attacks on the Christian
church and powerful French establishments. As his name
instantly evokes the battle against religious fanaticism yet the
love of tolerance and freedom of thinking.

41. Thomas Hobbes
Hobbes believed people are naturally selfish, cruel, and greedy.
► In 1651, he published a book called Leviathan. In this book, he wrote that people are driven by a restless desire for power.
► Without laws, people would always be in conflict.
► In such a “state of nature”, life would be “nasty, brutish, and short.”
► His idea: Governments were created to protect people from their own selfishness

42. Later Enlightenment thinkers might not have agreed with Hobbes…
►But, he was important because he was one of the first thinkers to apply reason to the problem of politics
►His ideas may sound harsh, but it was based on his own observations of human nature and reasoning

43. Montesquieu
Like Locke, Montesquieu was concerned with how to protect liberty from a bad government.
► He Wrote The Spirit of Laws in 1748. In this book, he described how governments should be organized.
► His idea: The separation of powers: By dividing different powers among more than one branch of government, no one
group in the government could grow too powerful

44. Each branch of government checked the other branches.
When powers were not separated this way, Montesquieu warned, liberty was soon lost.
He said: “When the legislative and executive powers are united in the same person…, there can be no liberty.”
► Lasting Impact: He greatly influenced the men who wrote the U.S. Constitution.
We now have a separate legislative (Congress), judicial (courts), and executive (President) branch

45. Cesare Beccaria: The Rights of the Accused
In the Middle Ages, torture of criminals was common.
The rack was often used, as well as devices like thumbscrews.
► Beccaria, an Italian, wrote a book called On Crimes and Punishments in which he argued against brutal
punishments
His ideas: A person accused of a crime should receive a fair and speedy trial. Torture should never be used.
Capital Punishment (death sentences) should be done away with.
► “For a punishment to be just it, should consist of only such gradations of intensity as to suffice to deter men
from committing crimes.”
This means that “punishment should fit the crime” and not be more than necessary to stop someone else from

46. Beccaria’s impact:
Beccaria’s ideas were adopted straight into our Constitution’s Bill of Rights. In fact the US 8th amendment
prevents “cruel and unusual punishment” for crimes, and the US 6th amendment provides for a speedy trial.
(The only exception is the Death Penalty, which we still have in the United States today.

bound to any Laws in which we have no voice.
