The Meaning of Scientific Revolution
The scientific revolution destroyed the medieval
world view in which the earth occupied the central
position, that heaven lay just beyond the fixed stars,
and every object had its place in a hierarchical and
qualitative order.
The church was losing credibility as more people were
becoming independent thinkers.
Science had given people reason to question the old
order.
Question: Can you identify 21st century examples?
Nicolas Copernicus (1473-1543)




The earth is a planet that orbits the sun along with
other planets.
He did not want to publish his work for fear of
controversy but was persuaded by his friends
(1543).
His theory offended the church which still
controlled the universities and the pulpit (church).
The book was banned (not allowed).
The book became a topic of popular discussion 50
years later.
Galileo




(1565-1642)
The astronomer and physicist who shattered the
medieval conception of the cosmos (spaces beyond
earth) and shaped the modern scientific outlook.
Rejected the church’s medieval division of the universe
into higher and lower realms (as explained by ancient
philosophers).
Built a telescope and made observations of the moon
and stars which were different than those of earlier
philosophers.
Discovered 4 moons that orbit Jupiter; that a celestial
body could move around another body other than the
earth; that the earth was not the common centre of
the universe; that a one body could orbit another while
orbiting the sun (moon around earth, earth around
sun).
Galileo

Galileo applied math to the study of movement



Rejected the idea that, when a rock falls it is because it is
striving to reach its proper place in the universe.
Rather, he said that motion is the relationship of bodies
to time and distance. He used math to demonstrate it.
Galileo challenged those who put faith in old
philosophers over investigative thinking and
considering new information and criticized Roman
Catholic authorities for suppressing modern science
In 1616 his works were censored (banned – not
allowed to be read), he was found guilty by the
Inquisition and imprisoned (house arrest). In 1820
(204 years later!!!) the church removed his works
from the censored list
Johannes Kepler (1571-1630)
Laws of Planetary Motion

1.
2.
3.
Discovered three basic laws of planetary motion
Planets move in elliptical (oval) orbits (NOT Circles)
Planets do not move at uniform speed (sometimes
they move faster and other times they move
slower) but accelerate as they near the sun
Found a mathematical relationship between the
time it takes a planet to compete its orbit of the
sun and its average distance from the sun which
can be used to calculate a planet’s position and
velocity (speed) at a particular time
Isaac Newton (1642-1727)
Explained the laws of gravity which linked the
astronomy of Copernicus and Kepler with the physics of
Galileo.
 Newton invented calculus which explained the physical
laws in mathematical equations.
Newton’s 3 Laws
1. The principle of inertia: that a body at rest remains at
rest unless acted on by a force, and that a body in
rectilinear motion (straight line) continues to move in
a straight line at the same velocity (speed) unless a
force acts on it. A moving body does not require force
to keep it in motion. Once started, bodies continue to
move. Motion is as natural a condition as is rest.

Newton (continued)
2.
3.
A given force (impact / bump) produces a
measurable change in a body’s velocity (speed /
movement). A body’s change of velocity is
proportional to the force acting on it.
For every action or force there is an equal and
opposite reaction or force. The sun pulls the earth
with the same force that the earth exercises on the
sun.
Francis Bacon (1561-1626)




Not a scientist but an advocate (supporter) of the
scientific method.
He believed that little progress had been made over
the years, because the church bent theories of nature
to support Christian scripture, which prevented
independent thinking and blocked new knowledge.
He advocated the Inductive Approach: careful
observation of nature and the systematic accumulation
(gathering) of data, drawing general laws from the
knowledge and testing through constant
experimentation. Sounds like a science laboratory!
He insisted on the need for verification.
Rene Descartes (1596-1650)
Creator of the deductive approach, which is derived
by following successive steps based on earlier
principles.
If this… then that…
 Descartes is also regarded as the founder of
modern philosophy. He believed that it was he who
was doing the doubting and thinking.
He said, “I think therefore I am”
Question: What does the above quote mean to you?
Write the answer down next the quote.

1.
2.
New ideas about the purpose of life became popular.
Such as, If earth is one of a billion planets,
Does God exist for only our earth or is there a God for
the entire universe?
If there are billions of planets, are there other intelligent
life forms out there and if so, what are their beliefs in
the all powerful being we refer to as God?
Answer the Questions and tell the class your opinion.
Louis Pascal (1623-1662) a French scientist and
Catholic believed that the eternal silence of
these infinite spaces could stir doubt,
uncertainty, and anxiety, which could
threaten Catholic belief.
Scholars set reason above all else…..
Reason comes first
Scholars:
 Believed that reason must serve religion
 Denounced magic spells, demons, witchcraft and astrology as vulgar
superstition
 Questioned all inherited opinions and traditions
 Religious the doctrine (reasoning) of religion
 Not all scholars attacked religion. Some claimed that they were
unveiling the laws of nature as created by God
The masses:
 Still believed in superstitions
 Still feared stirring the anger of the Christian God

The bible was no longer considered the literal
word of God.
The clergy began to lose their position (status)
as the judges of what was considered to be
knowledge.
God’s miracles were being explained as
naturally occurring phenomenon.
Debates raged over the senseless wars fought
in the name of religion.
Question: What is water boarding?
Discussion: What kind of people do this to other people?
In one of the first histories of all the world’s religions (published in 1723), the engraver Bernard
Picart depicted the Inquisition as cold and ruthlessly interrogating and as barbarous in its use of
torture. The bottom centre is the practice of water-boarding. (Bibliotheque des Arts Decoratifs,
Paris, France/Archives Charment/ The Bridgeman Art Library) See page 249 in your textbook.
Prison conditions during the enlightenment were awful.
Discussion: What are prison conditions like in the USA, Canada, China, Thailand, Mexico,
North Korea?
Christian View of Human Nature was Challenged
Philosophes criticized Christians for:
 for declaring that human nature is evil and humans as
helpless without God’s assistance and,
 for focusing on heaven instead of quality of our life on
earth
 for claiming their interpretation of the bible as truth
Philosophes argued that to establish an enlightened
society, the corrupt power of the church must come to
an end.
Question. How might two people grow to think and act
differently if one is raised according to the traditional
Christian view (above) and the other is raised to believe
that her nature is not evil and that she has control and
power over her own destiny?
The philosophes attempted to use the scientific
method to uncover societal defects and discover
ways to reform society.
Question. How can the scientific method help solve
some of the problems our society faces?
Write your answer down.
A possible answer to the question on the previous
slide is that yes, the scientific method has led to
new sciences. Psychology, sociology, economics
and politics are all fields of Social Science that have
helped to improve the plight of the less fortunate.
Examples include: Social programs, pensions,
insurance, international trade agreements,
treatments for depression, anxiety and post
traumatic stress disorder.
Discussion / Question: Write down a few examples of
how science has improved your life or the lives of
your family members or society in the 21st century?
Voltaire
(1694-1778)
Recognized as the leader of the French Enlightenment
 Exiled to England in 1720s
 He professed that Christianity was superstition and would be
destroyed by reason
 Christianity made no logical sense but they still committed
crimes and murdered each other to force obedience to their
beliefs, which benefitted a minority of religious leaders
Deists sought a natural religion of reason and science
 They rejected the Christian political power structure
 Denied the bible was God’s revelation, denied the virgin birth,
Jesus walking on water, the resurrection, and that the reward
for obeying Christian law was eternal reward in heaven.
Question: Do you have any of your own beliefs that can not be
supported by reason? Write your answer down.
Thoughts on Democracy
The philosophes favoured constitutional government
(very early modern democracy) but did not have
faith that the masses of people would make
competent participants in a democracy.
Question. Why do you think they felt this way?
Write your answer down.
The philosophes believed that because the masses
were not educated, that they did not have the skill
to think, reflect upon alternatives and be patient in
the search for good answers to societal problems.
They believed that because the masses were very
superstitious (religious), emotionally susceptible
because of inexperience in critical thinking.
They believed that the masses could be easily bribed
because they were poor (economically vulnerable).
Thomas Hobbes (1588-1679) Leviathan
Hobbes wrote,
“only unlimited power of a sovereign could contain the
human passions that disrupt the social order and
threaten civilized life; only absolute rule could provide
an environment secure enough for people to pursue
their individual interests”
Question.
What if the interests of the individuals (citizens) were
disapproved of by the person in power?
Would the citizen still be able to pursue his own
interests?
Hobbes was more pessimistic than most, about the
deficits (weaknesses) of human nature.
Most philosophes disagreed with his gloomy view of
human nature.
However, most philosophes agreed with his secular
approach to politics and his criticism of Divine Right
of Kings.
Questions.
What is the Divine Right of Kings?
If you agree with Hobbes criticism of the Divine Right
of Kings, explain your reasons.
Write your answers down.
Hobbes summarized
Critical of divine right of kings but did believe that
absolute power was necessary to contain the
human passions that disrupt the social order and
threaten civilized life
 People are selfish and characterized by competition
and dissention rather than cooperation
 His main concern was in protecting the social order
from human antisocial tendencies
Question: Do Chinese or American / Canadian society
have political structures to manage what Hobbes
describes?

A possible answer to the last question would be that
the CIA, CSIS, MI5, police and military in the 21st
century are agents of social control, which Hobbes
said were necessary.
Question. Name three social controls that you know
of in China and the USA or Canada.
John Locke
Locke’s believed that,
 human nature is Good
 People are born with Natural Rights to Life, Liberty, and
property
 The state should protect these Rights
 The state does not have the right to deny people of their
natural rights.
Locke disagreed with Hobbes justification of absolute monarchy.
He believed in Constitutional Government.
“The power to govern derives from the consent of the governed
and the state’s authority is limited by agreement…Rulers hold
their authority under the law and when they act outside the
law, they forfeit their right to govern.”
Both Hobbes and Locke agreed that the state needs to exist to
provide for the security and well being of the citizens, but
they had totally different ideas of how to achieve it.
Locke Summarized




People have the capacity for reason and freedom
We are born Free and we are born Rational
Political life can be guided by rational principles
We have a right to resist despotic authority
The American Declaration of Independence restated
Locke’s principles to justify the American Revolution
 Natural Rights
 State interference with personal property leads to
the destruction of liberty
The World’s Policeman
A common belief around the globe is that the USA
interferes in affairs of other independent nations
simply to maintain its own economic advantage.
Can you now see that their interference may be based on
a fundamental difference in VALUES and RIGHTS.
Think about the differences in regimes. USA vs. Iraq, Iran,
Russia, Libya, Syria.
Question.
1. If you had to leave China today and live in one of the
countries named above, which country would you
choose?
2. Why would choose that country over the others?
Write your answers down and explain your reason.
Question. Do you think that humans are born selfish,
with the inability to cooperate and competitive to
the point of self destruction or do you believe that
humans are essentially good?
Question. If all of the citizens of China could vote
today, and pick either Hobbes or Locke’s method of
rule, which do think they would choose?
Why would they make the choice they did?
Montesquieu
(1689-1755)
Spirit of Laws was published in 1748. He believed,
1. Political and social behaviour must be studied in
relation to geographic, economic, and historic
conditions. This sounds like modern political science.
2. Each society requires constitutional forms and laws
that pay heed to the character of its people.
3. Considered despotism corrupt because it was
unchecked by law. The despot can do what ever he
wants, without regard for the suffering of the people,
but thinking only of his own passions at the expense
of all others.
4. In despotic society, economic activity slows to a halt,
because entrepreneurial people fear the loss of their
efforts.
Discussion. Give examples of each in history and today.
Montesquieu’s recommendations
Separation of powers:
1. Legislative – law makers (politicians)
2. Executive – civil servants
3. Judiciary – judges
Question. Why is it that if the same group that
prosecutes a crime (executive) is the one that
judges it (judiciary), liberty can not be preserved?
In a good government, one power balances another
power.
The liberal tradition took from Montesquieu:
1. constitutional government
2. the rule of law
3. separation of powers
4. freedom of thought
5. protection of individual liberty
6. religious toleration
Question.
To what extent do these things exist in the west and east
today?
Write your answers down.
Voltaire
Hated arbitrary power because it is based on individual
choice and not subject to established law
 Freedom meant and established code that governed all
people equally
However, Voltaire was not a democrat.
He did not have confidence in the abilities of the common
people to participate in government
He did encourage the following reforms
1. Freedom of the press
2. Religious toleration
3. A fair system of criminal justice
4. Proportional taxation
5. Reduction of privilliges of the clergy and nobility

Rousseau
In the Greek tradition of the city state and the polis,
Rousseau promoted
1. a community in which the citizens participated in the
decision making
2. a democracy where all men participated as members
of a committed community
3. Citizens, not their representatives, as the governors
4. equality
He condemned despotic monarchy, the divine right
theory of kingship and the view that the people should
be governed by the Lords and Clergy who inherited
positions and benefited from special privilege
Rousseau’s Critics
His critics say that his hope for a body of citizens that
think alike, comes close to a collectivism and
totalitarianism
He did not value constitutional limitations (division of
powers) or consider safeguards to protect individual
and minority rights from a tyrannical majority
He rejected Locke’s view that citizens posses
independent rights and that citizens have the right
to act against the state
Question and Discussion. Do you think that citizens
should possess the right to act against the state?
Read and Comment in class
Read the SOCIAL AND ECONOMIC THOUGHT
Page 254 (bottom left section of the page only).
Question.
1. What does this mean to you?
2. Pick one idea from this paragraph and tell the class
what it means to you.
3. Prepare a 1 minute talk and be prepared to discuss
it.
Locke’s essay (1690)
Concerning Human Understanding
Locke argued that,
1. the human mind is a blank slate, empty of opinion
and bias, at the time of birth.
2. the human mind forms impressions and opinions
based on contact and experience with the world.
3. knowledge and beliefs are derived from
experience.
4. Individuality is derived from personal experiences.
Questions. Who are you? What do you think about
this? Write down your answers.
The implications of his essay…
If humans are born a blank slate, with no innate
(preprogrammed) ideas, then humans, contrary to the
Christian doctrine (religious beliefs) are not born with
Original Sin and are not depraved (bad) in nature.
If people are provided with a healthy environment
(discuss this), and education, they will behave morally,
they will become intelligent and productive citizens.
The philosophes believed that evil came about from bad
influences and institutions and a poor education.
Question. Why do you agree or disagree with this?
Rousseau’s Emile (1762)
Read aloud, page 254 – last two paragraphs.
This work is considered to be the most important
work of the Enlightenment educational thought.
Discussion:
How is this thinking different from that which
governed your childhood and early school years?
How is this educational thought brought to life at JLU?
Freedom and conscience of thought
The philosophes considered religious persecution to
be humanity’s most wicked offense against reason.
The examples that demonstrate the greatest offenses
were,
1. the Catholic Church’s burning of heretics (non
Catholics) and
2. the slaughter of Muslims and Jews during the First
Crusade.
Censorship of Philosophes ideas
Then: The Church regularly burned books that
expressed ideas that led people to question the
position of the Catholic Church.
Consider the quality of life for people that lived in a state
which attempted to control their thinking by making
the choices for them, as to what they could read and
think about.
Consider the life of the people who lived in a state that
punished people for expressing ideas that were
different than those of the rulers.
Now: The west only restricts speech when it gets to
the point where it promotes hate.
Question. Has China eased its restrictions on censorship
and freedom of speech in the past decade?
Philosophes opinion of War
War is barbaric and without reason.
War is the idea of power hungry monarchs and
supported by fanatical (crazy) clergy, wicked army
leaders and ignorant commoners (those who
choose to not reflect on the consequences of their
actions).
There is nothing heroic about battle.
Question. When is war and violence justified?
Write you answer down.
Philosophes on Slavery
Slavery violates the fundamental principle of justice
and is derived from the base human desire to
dominate and exploit other human beings.
Some would say that the argument for slavery is
similar to the argument that says that a man has a
right to beat his wife if she displeases him.
Question. Were comfort women slaves?
“Men and their liberty are not objects of commerce;
they can be neither sold nor bought”
Philosophes on Women’s Rights
Most philosophes viewed women as intellectually and
morally inferior (less) to men.
Most philosophes believed that nature gave men
power over women and that women have
infirmities that are not curable.
See Rouseau’s quote on the bottom of page 256.
The result of the philosophes arguments for equality
and liberty and an end to slavery, laid the
foundation for the beginning of the Women’s
Movement.
Question. What is the Women’s movement?
Adam Smith and Laissez-Faire Economics
Adam Smith (1776) An Inquiry into the Nature and
Causes of the Wealth of Nations
Mercantilism ~ definition ~ the state should regulate
business, control the resources of the nation,
encourage exports, discourage imports and build up
reserves of precious metals.
Smith argued that Mercantilism was the wrong way to
measure the wealth of a nation.
Question. Do you agree or disagree with Smith?
Why?
Write your answer down.
Laissez-Faire Economics
Smith believed:
1. The real basis of a country’s wealth is measured by the
quantity and quality of its goods and services, not by
its store of precious metals.
2. He argued that the state should not interfere with the
market.
3. The state should limit its authority to justice and
national defense.
Question. Using this historical perspective on economic
theory, explain how The Peoples Republic of China has
adopted some these ideas over the past 25 years?
North America (1775)
The French and English continued to fight over their
claims in the New World.
By 1775, the British victory over the French, in North
America, deprived the French of almost all their
colonies.
The cost to the British, to win the war and protect the
colonists from the French and to continue to
provide troops to assist the colonists in the defense
against Native North Americans was very expensive.
British citizens were heavily taxed. Colonists
rebelled against import duties and taxation.
July 4th, 1776 – The American Colonies adopted the
Declaration of Independence, written by Thomas
Jefferson, based on the Theory of Natural Rights of
Locke.
Each of the 13 colonies had its own elected assembly
and the Americans quickly gained political
experience and the skill to govern themselves.
The Enlightenment ideals which included confidence
in reason, freedom of religion and thought and the
principle of natural rights was strong in America.
Statement.
It is often said that the USA is a very young country with
very new traditions, little substance and not much
history in comparison to the east.
Question.
If the colonizers and early immigrants to the USA were
Europeans who chose to live by the philosophes ideals,
is the above statement not really accurate?
Considering that western civilization began 5,000 years
ago in Mesopotamia and the USA is simply another
western territory, it is easy to argue that North
Americans also have a 5,000 year old history.
American Victory (1783)
George Washington was a great leader.
The French helped the Americans with money and
supplies and entered on the side of America in
1778.
Britain had difficulty transporting supplies across the
ocean while fighting the French in the West Indies
and elsewhere and could not commit to ensure
victory.
American victory was seen as success against tyranny.
The 13 states drafted constitutions that,
1. Protected individual rights
2. Rejected Monarchy and hereditary aristocracy
3. Derived power from the people
4. Separated powers and included checks and
balances to safeguard against abuse of power
5. Included a Bill of Rights to protect individual
human rights
Slaves and Women did not share these freedoms, but
to the rest of the world, it appeared that
Americans were creating a freer and better society.
The Enlightenment
and the Modern Mentality
The Legacy of the philosophes:
1.
2.
3.
4.
5.
Scrutinized authority and tradition
Valued science and technology as a means for
promoting human betterment
Wanted to free the mind from bonds of ignorance and
superstition and rescue people from intolerance cruelty
and oppression
Because of the philosophes efforts, torture, which was
endorsed by the Christian Church and their states, was
abolished
The norm moved towards religious toleration, freedom
of speech and freedom of the press
Europe to America
The Declaration of Independence (1776) Articulated
Locke’s principles
1.
2.
3.
Government derives it authority from the people being
governed
Human beings are born with natural rights and the
government has a responsibility to protect them
Citizens have the right to resist a government that deprives
them of these rights
The Declaration of Independence included
Mostesquieu’s principle of separation of powers,
to safeguard against despotic power
Human Nature
broke
Philosophes
with the traditional Christian
views. Philosophes said that
1. humans are not born in sin
2. that suffering and misery are not ordained by God
3. relief from suffering was not only God’s to give
4. social inequality was not God’s decision (divine
right)
5. Eternal damnation was not a fair punishment for
not following the bible as the law
The philosophes saw injustice and suffering as a man
made problem that could be solved through
reason.
Did the Philosophes make a difference?
With all the progress that seemed to come about
from the ideas of the Philosophes, how did the
atrocities of the 20th Century manage to occur?




World War I and World War II
The near genocide of the Jews by German Nazis
State sponsored mass murder and numerous near
genocides of other people from around the world
Development of weapons of mass destruction
The ideas of the philosophes remain intact and
students of history are able to keep them alive for
future generations to learn from.
