The Age of Reason
The Scientific Revolution and the Enlightenment
Copernicus
Polish priest and astronomer; advocated for heliocentric theory through logic, not observation. Shift from Earth-centered to Sun-centered system creates uncertainty about the human role in the universe as well as God's location. Catholic + Protestant leaders alarmed by new heliocentric theory.
Galileo
First European to make systemic observations of the heavens using a telescope beginning a new age of astronomy. Confirms Copernicus's heliocentric theory. Pope condemns Galileo for his theory's which contradicted the teachings of the church; he was put on trial and sentenced to house arrest.
Heliocentric Theory
Theory which states that the sun is the center of the universe. Developed by Age of Reason astronomers such as Copernicus and Galileo.
Geocentric Theory
Theory which states that the Earth is the center of the universe. Geocentric Theory was taught by the Catholic Church prior to the Age of Reason.
Newton
English mathematician, physicist, astronomer, theologian, and author. Newton's major work was his Mathematical Principles of Natural Philosophy, also known as Principa. In Principa, Newton uses mathematical proofs demonstrating his universal law of gravitation.
Galen
Greek physician. Influenced knowledge of anatomy, physiology, and disease. Relied on animal, rather than human dissections to learn about human anatomy, leading to inaccuracies in his findings.
William Harvey
His famous work, On the Motion of the Heart and Blood, disputes Galen's work. Conducted experiments on convicted murderers to learn more about organ functions and digestion.
Francis Bacon
Encouraged scientists to build knowledge through "inductive reasoning" by combining careful observation and systematic experimentation to collect small bits of information.
Rene Descartes
Advocated for scientists to build knowledge through "deductive reasoning" by using both observations and reasoning to come to conclusions.
