1) An object in motion
will remain in motion
2) Force = mass X
acceleration

18th century Enlightenment – The Age of Reason
 Revolution in philosophy
 Philosophers, inspired by scientists, started
questioning God and God’s role in society
 Particular emphasis was placed on criticizing
government and the church
 Paris, France was the hotbed of reason – rather
ironically, it was also the center of Absolutism and
Divine Right
 Philosophers wrote the words that inspired
revolutionaries, both in America and in France
THE INFLUENCE OF THE
ENLIGHTENMENT
 One of the main issues that was discussed during this
time was the role of government
 Enlightenment thinkers (philosophes) contributed
many ideas to this debate:
 John Locke
 Voltaire
 Jean-Jacques Rousseau
John Locke and Jean Jacque Rousseau
 Locke
 Rousseau
 English philosopher
 French Philosopher
 Believed that men are
 Believed that all men are
entitled to life, liberty and
PROPERTY
 Inspiration for the
American founding
fathers (all were rich,
white, educated men)
 Government should
protect us from us – first
priority was to provide
security and order
entitiled to life, liberty
and EQUALITY
 Inspiration for the French
revolutionaries (many
women and poor
commoners)
 Government should
promote equality among
all men
John Locke and Jean Jacques Rousseau
The “Social Contract”
Men form governments.
Governments must respond to the
needs of men.
If a government does not respond
to the needs of men, men have the
right to change the government.
Views on the Social Contract
 Who are the “men”? Who determines whether or not the government is
serving the needs of men?
 What does it mean to “change” the government?
 There have been different answers to these questions from throughout
history……………..
 Locke
 Rousseau
 American Founding Fathers
 French Revolutionaries
 Karl Marx
 Southern leaders in the US in 1861
 Vladimir Lenin
 Chairman Mao
Voltaire
 French philosopher who
attacked the Church and
the French government
though his short novel,
Candide and other works
 Advocated freedom of
religion and separation of
church and state
 Advocated the right of
citizens to a fair and
impartial trial
Adam Smith
 English economist and
philosopher who attacked
the idea of government
intervention in the
economy
 Advocated “laissez-faire”
economics (hands off)
 Believed in a pure
capitalist system where
the “law of supply and
demand” would determine
prices
David Hume
 English philosopher who
questioned the existence of
God
 Used a logical and scientific
argument to question faith
 Since faith itself is
irrational, what makes one
faith right for everyone?
 Heavily criticized by the
Anglican Church, of which
he was a member, but never
wavered in his views
Deism and the Watchmaker Theory
 Enlightenment age religion that advocated a belief in God (even if that

belief was irrational)
God was there in the beginning, and will be there in the end, but in
between we’re on our own
Imagine an old style windup watch……God made the watch and
wound it up, but then left it alone. He’ll be back when the watch
needs to be rewound
No need for prayer or worship – it’s counterproductive – God’s not
listening anyway
Humans have ultimate free choice and free will
Many of the American founding fathers believed in Deism – Thomas
Jefferson was probably the most famous
Voltaire also advocated Deism and the right to freedom of religion
The Results of the Enlightenment
 Reason is used to justify different forms of
government-not everyone agreed on what was best!
 Voltaire-Monarchy, Rousseau-Democracy
 Stimulated religious tolerance
 Progress is encouraged
 Will help spark an Industrial Revolution
 Inspired revolutions in the United States, France,
and Latin America
 Citizens questioning the role of government
The American Revolution
The American Revolution
 Not really a classic “revolution” in the sense that a social class did
not revolt against the one above it
 Really more of a war for independence, but it did incorporate
rhetoric from the Age of Reason
 American revolutionary LEADERS studied Locke and others –
they certainly believed in the rhetoric, but the average “patriot” in
the street paid little in the way of taxes, so “no taxation without
representation” was little more than a slogan.
 The new government formed after the revolution was at least
outwardly based on enlightenment principles, although it would
be decades before most of those principles were actually put into
practice – think of how long it took women to receive the vote.
Declaration of Independence
 Written by Thomas
Jefferson
 Restatement of the social
contract
 List of grievances – what
King George III did to
break the contract
 Considered the first true
government document
containing enlightenment
principles
 Used as a pattern for
revolutions around the
world
Enlightened Despotism
in Central and Eastern
Europe
Enlightened Despotism
 Idea found in Central and Eastern Europe whereby monarchs
and emperors made changes to their societies in which
modernized the states while the people earned some political
and social rights
 Monarchs still maintained absolute control, but instead of
justifying their rule by divine right (God), they instead saw
themselves at the head of the people
 Most of the ideas were really designed to PREVENT
revolution (governments must serve the needs of men)
 Many of the reforms were eventually rescinded after the
people tried to get even more rights (revolutions were often
brutally repressed
Fredrick the Great of Prussia
•Emperor of Prussia in the
Northern Germanic Lands

Catherine the Great of Russia
 Modernized the Russian army
and government
 Studied in France during the
Enlightenment
