ENLIGHTENMENT
LEARNING OBJECTIVE: Explain how the scientific world influenced society and thought.
“Science” Before the Scientific Revolution
• Based almost entirely on reasoning
• Experimental method or observation wasn’t used at all
• Science in medieval times• Alchemy
• Astrology
A medieval alchemist
Factors Leading to the Scientific Revolution
• Rise of universities
• Contact with non-Western societies
• The Renaissance
• Exploration
Scientific Revolution
• Background:– Challenging Old Ideas: Revolutions
• 1. Renaissance challenged the notion that only the Church had the right answers. New Idea: the individual. A cultural revolution
• 2. Reformation challenged accepted religious ideas on God, salvation and the soul. It also challenged the notion of one church and Papal control. A religious revolution
• 3. Scholars began to question old accepted ideas about the Earth and universe: Scientific Revolution
Scientific Revolution
• Background:– Prior to 1500’s… truth regarding the functioning of
the Earth and universe, most scholars relied on Greek and Roman philosophers/scientists and the Bible.
• Most did not test these ideas for their correctness. – By the mid-1500’s this changed. Scholars began to
test and question the ancient thinkers.• Old assumptions became replaced with new theories.• This led to a change in the way people thought: Scientific
Revolution.
Scientific Revolution
• The Earth and Universe– Middle Ages: Earth seen as unmoving, at the
center of the Universe. The moon, sun and all planets revolved around the earth in perfect circular orbits.
• This view was supported by Aristotle and Ptolemy: Geocentric Model or earth-centered theory.
• The Church taught that God had deliberately done this because Earth had a special place.
SCIENTIFIC METHOD
Scientific Revolution• Scientific Method:
– A) Procedure begins with a problem or question arising from observation
– B) A hypothesis (unproven assumption) is formed– C) Hypothesis is then tested by experimentation
and data collection.– D) Analyze and interpret data to reach a new
conclusion proving or disproving hypothesis.• ***New Thinking: relying on individual abilities.

COPERNICUS
• Polish scholar • Proposed the idea
of a heliocentric or sun-centered universe – The Earth was one
of several planets to revolve around the sun
Models of the Universe:
Geocentric vs. Heliocentric Geocentric: the Earth is at the center of the universe; all heavenly bodies move around the Earth
Heliocentric: the Sun is at the center of the universe; all heavenly bodies move around the Sun—including the Earth
COPERNICUS’ SOLAR SYSTEM
GALILEO
• Observed Jupiter’s moons orbiting that planet
• Condemned by the Catholic Church
• His ideas challenged Christian teachings – That heavens were
fixed, unmoving & perfect
GALILEO FACING AN INQUISITION
• 1633- tried before the inquisition – Threatened with
excommunication unless he withdrew his heresies
• Agreed to state publicly that the Earth stood motionless at center of the universe
SIR ISSAC NEWTON
• Proved Galileo correct
• Defined the Law of Gravity
• Invented calculus• His laws became the
starting point for investigating everything in nature.
LAW OF GRAVITY
Scientific Revolution--Enlightenment
• Rene Descartes: mid-1600’s:– French Philosopher and scientist – One of the most influential
advocates of science.– Wrote: “Discourse on Method”:
Argued that all thought had to follow the clear, orderly progression of scientific reasoning. Everything has to be proved.
– The use of reason was vital: clear, rational, logical thinking.
Scientific Revolution-----Enlightenment
• Sir Francis Bacon:– Believed science would help
humanity conquer nature and would end all suffering in the world.
• The scientific method will move from a strict scientific use to all realms of thinking including political, social.
Exit Ticket

people viewed the universe? • Why did the Catholic church have such
strong opposition to the scientific view? • In your own words describe what the
scientific method is.
