I have heard a number of people assert that Christianity gave birth to the scientific method. Perhaps, the first time I heard that claim was from John Lennox, the famous Oxford University professor of mathematics. I was intrigued, but I didn’t take the time to research his claim at the time.
I have heard the claim repeated multiple times, most recently by Dr. Michael Guillen the astrophysicist, former Harvard professor and TV personality. In fact, he devoted a podcast to the subject (embedded below), so I figured it was time to learn more.
I started with Wikipedia, which has a page on scientific method. Wikipedia begins with Aristotle and focuses on rationalism as the basis for scientific method.
Properly speaking, rationalism is not a method. It is a philosophy, a way to approach the world. Rationalism and Aristotle, though, seem to have led the way to the development of the scientific method.
Aristotle’s inductive-deductive method that depended on axiomatic truths and the “self-evident concepts” developed by Epicurus was an early conception of the way to do science. It was jettisoned, however, for something more like the modern scientific method beginning around the 16th Century. Perhaps, this is why Guillen doesn’t mention Aristotle, except in passing.
After those early pioneers, Wikipedia references some great Muslim thinkers who were influenced by Aristotle (including Avicenna (Ibn Sina) and Averroes (Abū l-Walīd Muḥammad Ibn ʾAḥmad Ibn Rušd)). They placed “greater emphasis on combining theory with practice”, focusing on “the use of experiment as a source of knowledge”. Guillen starts his history of scientific method with these early “flashes” of scientific method in the Muslim world.
These men of the Islamic Golden Age pioneered a form of scientific method, but the inertia did not continue. Moses ben Maimon (Maimonides), the great Jewish theologian, physician, and astronomer, developed a similar emphasis on evidence. He urged “that man should believe only what can be supported either by rational proof, by the evidence of the senses, or by trustworthy authority”. He foreshadowed a future scientific posture, but his prescience also did compel further advancement at the time.
Dr. Guillen credits Robert Grosseteste and Roger Bacon with the formation of the first actual principles of scientific method. Their ideas “caught fire” in Christian Europe from the tinder of academies that began just after the turn of the first millennium, igniting a blaze that would fuel scientific inquiry and endeavor for centuries to come.
“Concluding from particular observations into a universal law, and then back again, from universal laws to prediction of particulars”, Grosseteste emphasized confirmation “through experimentation to verify the principles” in both directions.
Roger Bacon, Grosseteste’s pupil, “described a repeating cycle of observation, hypothesis, experimentation, and a need for independent verification”, including the recording of the way experiments were conducted in precise detail so that outcomes could be replicated independently by others. Bacon’s methodology lead to the modern emphasis on peer-review in science, says Guillen.
Wikipedia mentions Francis Bacon and Descartes. Bacon and Descartes emphasized the importance of skepticism and rigid experimentation, expressly rejecting Aristotle’s dependence on first principles (axioms). Guillen, however, glosses over Descartes to get to Galileo Galilei and Isaac Newton.
Galileo Galilei introduced mathematical proof into the process and continued to distance science from reliance on Aristotelean first principles. Galileo and Newton reformulated the terms of scientific method that would inform modern scientists ever afterward.
That the two latter men were men of faith, along with Grosseteste (a Catholic Bishop) and Roger Bacon, his student, is significant. Maimonides and the Islamic thinkers before him were also men of faith. These men who pioneered the way to modern science were all monotheists who believed in a creator God.
Science did not really take off until the 17th Century. The trailblazers of the modern scientific method were religious men, and the modern scientific method was born in the religious environment in Christian Europe lead, primarily, by men of faith.
Why did science catch fire in Christian Europe and not in other parts of the world? Why not in China? Or in the world of the eastern religions? This is a question Guillen poses, and he provides a possible answer.
