Can someone give me an example of rational inquiry into the natural world during the Middle Ages, particularly by a religious person? I’m debating somebody.
Sure, how many would you like?
Here is a small sampling:
Scientific activity in medieval Europe was maintained by the activity of a number of significant scholars, active in a wide range of scientific disciplines and working in Greek, Latin, and Arabic-speaking cultures. This list provides a brief summary of their work.
John Philoponus (ca. 490–ca. 570), also known as John the Grammarian, a Byzantine Christian philosopher, launched a revolution in the understanding of physics by critiquing and correcting the earlier works of Aristotle. In the process he proposed important concepts such as a rudimentary notion of inertia and the invariant acceleration of falling objects. Although his works were repressed at various times in the Byzantine Empire, because of religious controversy, they would nevertheless become important to the understanding of physics throughout Europe and the Arab world.
Paul of Aegina (ca. 625–ca. 690), considered by some to be the greatest Byzantine Christian surgeon, developed many novel surgical techniques and authored the medical encyclopedia Medical Compendium in Seven Books. The book on surgery in particular was the definitive treatise in Europe and the Islamic world for hundreds of years.
The Venerable Bede
The Venerable Bede (ca. 672–735), a Catholic monk of the monasteries of Wearmouth and Jarrow who wrote a work On the Nature of Things, several books on the mathematical / astronomical subject of computus, the most influential entitled On the Reckoning of Time. He made original discoveries concerning the nature of the tides and his works on computus became required elements of the training of clergy, and thus greatly influenced early medieval knowledge of the natural world.
Rabanus Maurus (c. 780 – 856), a Catholic monk and teacher, later archbishop of Mainz, who wrote a treatise on Computus and the encyclopedic work De universo. His teaching earned him the accolade of “Praeceptor Germaniae,” or “the teacher of Germany.”
Pope Sylvester II (c. 946–1003), a Catholic scholar, teacher, mathematician, and later pope, reintroduced the abacus and armillary sphere to Western Europe after they had been lost for centuries following the Greco-Roman era. He was also responsible in part for the spread of the Hindu-Arabic numeral system in Western Europe.
Constantine the African (c. 1020&–1087), a Catholic native of Carthage, is best known for his translating of ancient Greek and Roman medical texts from Arabic into Latin while working at the Schola Medica Salernitana in Salerno, Italy. Among the works he translated were those of Hippocrates and Galen.
Avempace (died 1138), a famous physicist from Muslim Spain who had an important influence on later physicists such as Galileo.[1] He was the first to theorize the concept of a reaction force for every force exerted.[2]
Adelard of Bath (c. 1080 – c. 1152) was a 12th-century Catholic Churchman and English scholar, known for his work in astronomy, astrology, philosophy and mathematics.[3]
Robert Grosseteste (1168–1253), Bishop of Lincoln, was the central character of the English intellectual movement in the first half of the 13th century and is considered the founder of scientific thought in Oxford. He had a great interest in the natural world and wrote texts on the mathematical sciences of optics, astronomy and geometry. In his commentaries on Aristotle’s scientific works, he affirmed that experiments should be used in order to verify a theory, testing its consequences. Roger Bacon was influenced by his work on optics and astronomy.[6]
St. Albert the Great
St. Albert the Great (1193–1280), Catholic Doctor Universalis, was one of the most prominent representatives of the philosophical tradition emerging from the Dominican Order. He is one of the thirty-three Saints of the Roman Catholic Church honored with the title of Doctor of the Church. He became famous for his vast knowledge and for his defence of the pacific coexistence between science and religion. Albert was an essential figure in introducing Greek and Islamic science into the medieval universities, although not without hesitation with regard to particular Aristotelian theses. In one of his most famous sayings he asserted: “Science does not consist in ratifying what others say, but of searching for the causes of phenomena.” Thomas Aquinas was his most famous pupil.
