Medieval Philosophy (c. 400–1400 CE)
1. What is it?
Medieval philosophy is the philosophy that developed in Europe during the Middle Ages.
It was strongly influenced by Christianity, but also by Greek philosophy (especially Plato and Aristotle) and later by Islamic and Jewish thinkers.
The main focus was:
How do faith and reason fit together?
Can we prove God’s existence with logic?
What is the relationship between the soul and the body?
How should humans live in harmony with God’s will?
2. Early Medieval Philosophy (400–1000 CE)
St. Augustine (354–430):
Blended Christianity with Plato’s ideas.
Believed true happiness comes only from God.
Wrote The City of God, where he contrasts the “City of Man” (earthly, sinful) with the “City of God” (spiritual, eternal).
Boethius (480–524):
Wrote The Consolation of Philosophy in prison.
Argued that fortune is temporary, but true happiness is found in wisdom and God.
3. High Medieval Philosophy (1000–1300 CE)
This period is called Scholasticism: philosophy taught in universities, trying to use reason and logic to explain faith.
St. Anselm (1033–1109):
Famous for the ontological argument: God must exist because the very idea of a “greatest being” means He exists.
Averroes (Ibn Rushd, 1126–1198):
Muslim philosopher who studied Aristotle.
His writings influenced Christian scholars in Europe.
Maimonides (1135–1204):
Jewish philosopher.
Wrote The Guide for the Perplexed about faith and reason.
Thomas Aquinas (1225–1274):
The most important medieval philosopher.
Blended Aristotle with Christianity.
Wrote Summa Theologica.
Gave Five Ways to prove God exists (e.g., motion, cause, design).
Believed faith and reason never truly conflict.
4. Late Medieval Philosophy (1300–1400s)
William of Ockham (1287–1347):
Known for Ockham’s Razor: the simplest explanation is usually the best.
Argued we can’t prove God’s existence with reason alone faith is necessary.
This period started moving toward Renaissance Humanism, which focused more on human potential and less only on God.
5. Why Medieval Philosophy Matters
It built the bridge between Ancient philosophy and Modern philosophy.
Preserved Greek ideas (Plato, Aristotle) through the Middle Ages.
Developed methods of logic and debate still used in schools and universities today.
Shaped Christian theology, but also interacted with Islamic and Jewish thought.
Short version:
Medieval philosophy tried to unite faith and reason. Thinkers like Augustine and Aquinas believed philosophy could help explain and defend Christian beliefs. It laid the foundation for modern science, politics, and philosophy.
