Nicole Oresme (c. 1320–1325 – July 11, 1382) was a significant philosopher of the later Middle Ages. He wrote influential works on economics, mathematics, physics, astrology and astronomy, philosophy, and theology; was Bishop of Lisieux, a translator, a counselor of King Charles V of France, and probably one of the most original thinkers of 14th-century Europe.

Oresme was known to be a well-rounded psychologist. He practised the technique of “inner senses” and studied the perception of the world.

In 1348, he was a student of theology in Paris. In 1356, he received his doctorate and in the same year, he became a grandmaster (grand-maître) of the College of Navarre. In 1364, he was appointed dean of the Cathedral of Rouen. Around 1369, he began a series of translations of Aristotelian works at the request of Charles V, who granted him a pension in 1371 and, with royal support, was appointed bishop of Lisieux in 1377. In 1382, he died in Lisieux.
