Medieval philosophy is the philosophy in the era now known as medieval or the Middle Ages, the period roughly extending from the fall of the Western Roman Empire in the 5th century A.D. to the Renaissance in the 16th century.
Medieval philosophy is characteristically theological. All the main branches of philosophy today were a part of Medieval philosophy.
The principles that underlie all their work are:
- The use of logic, dialectic, and analysis to discover the truth, known as ratio;
- Respect for the insights of ancient philosophers, in particular Aristotle, and deference to their authority;
- The obligation to co-ordinate the insights of philosophy with theological teaching and revelation.
