g of the World
Causes Medieval Intellectual Life and
Medieval Universities: scholasticism
The Italian Renaissance
Renewed emphasis on mathematics
Renaissance system of patronage
Navigational problems of long sea voyages
Better scientific instruments
The “Science” of Aristotle
Derived from Aristotle’s “physics” & Ptolemy’s “astronomy”
Geocentric view of the universe
The Science “Revolution”?
Not even called “science” – it’s “natural philosophy”
New ideas, new inventions
Telescope (Dutch!)
Microscope (Dutch too!)
Efforts to measure longitude among the largest scientific endeavors of the era
Nicolaus Copernicus (1473-1543) Polish, Catholic priest, astronomer
Publishes On the Revolution of the Heavenly Spheres while on his deathbed (afraid to challenge the church)
Proposes a heliocentric view of the universe which better explains planetary motion
Inaccurate, but it “opens the door”
Tycho Brahe (1546-1601)
Arrogant, wealthy Danish noble
Supported geocentric view, but had a sophisticated observatory
Gathered huge amounts of data (saw comets shooting “through the crystalline spheres”)
Johannes Kepler (1571-1630)
Brahe’s assistant, but supports the heliocentric view
Posits elliptical orbits, non-uniform speeds to explain anomalies
Publishes New Astronomy in 1609; still unclear why objects “orbit”
Galileo Galilei (1564-1642)
Italian points his Dutch-made telescope at the skies
o Medici were his patrons; originally named
moons of Jupiter after them
Advocates heliocentric view based on observations
o Publishes Starry Messenger & Letters on Sunspots
Argues mathematical laws control the universe
Sir Isaac Newton (1642-1727)
Addressed issue of how the planets moved: ties it all together
Principia Mathematica reasons that mutual attraction (gravity) governs relationships between objects
Built on empiricism: need to observe before explaining
Argues a universe governed by natural laws
Philosophy & the “New Science”
Nature as mechanism: what is “God’s role” in this view?
Focus shifts to mathematical explanations of the world
Shift to knowledge as means of improving lives (& strengthening state)
Francis Bacon (1561-1626) “Father” of:
o Empiricismo Inductive Reasoningo Scientific Method
Attacks concept that most truths already discovered
Encourages innovation, research (in contrast to Renaissance thinkers?)
Use knowledge to improve human condition; links science to progress, progress to strong government
Rene Descartes (1596-1650)
Deductive reasoning
Discourse on Method, 1637, focuses on mathematical model, in French
Cogito, ergo sum
Dualism
Primary influence on philosophers, logicians
Political Philosophy: Hobbes v. Locke
Political Philosophy: Thomas Hobbes Leviathan (1651) in wake of English Civil War
o Describe man in a “state of nature”
o “[T]he life of man [in the state of nature is] solitary, poor, nasty, brutish, & short.”

o Describe man in a “state of nature”
o Consent of the governed
o Natural rights
o Social contract w/ government
o What if government fails to protect natural rights?
o Essay Concerning Human Understanding & the Tabula Rasa
