Chapter 1: Renaissance, Scientific Revolution & Enlightenment Thought

1. The Renaissance & Humanism

Originating in 14th-century northern Italian city-states (Florence, Venice), the Renaissance (Rinascimento) represented a rebirth of classical Greco-Roman learning, prioritizing Secular Humanism:

  • Literary Pioneers: Petrarch (Father of Humanism), Boccaccio (Decameron), and Niccolò Machiavelli (The Prince - autonomous political realism).
  • Visual Arts: Linear perspective and anatomical precision by Leonardo da Vinci, Michelangelo, and Raphael.
  • The Printing Press (c. 1440): Johannes Gutenberg's movable metal type mechanized book production, shattering clerical information monopolies.

2. The Protestant Reformation & Scientific Revolution

  • Protestant Reformation (1517): Martin Luther nailed the 95 Theses to the Wittenberg church door, attacking papal indulgences and advocating Sola Scriptura (Scripture alone) and Sola Fide (Faith alone).
  • The Scientific Revolution:
    • Nicolaus Copernicus (De revolutionibus 1543): Heliocentric cosmology replacing Ptolemaic geocentrism.
    • Galileo Galilei: Telescopic confirmation of heliocentrism; laws of falling bodies.
    • Isaac Newton (Philosophiae Naturalis Principia Mathematica 1687): Universal Gravitation and three laws of motion.
