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 Argues for absolute power (of whom?)

o Why do people object?

Political Philosophy: John Locke Second Treatise of Government (1690)

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
