The fact that Charles Darwin originated the concept of natural selection is a popluar notion. However, evolutionary concepts long predated The Origin of Species. In the Historical Sketch section of the sixth edition, even Darwin discusses the contributions of forty-four authors that had previously written on the subject of evolution, including Aristotle.

Darwin recognized that Aristotle’s concepts were compatible with natural selection. On the evolution of teeth, in The Origin of Species, Darwin wrote,

“We here see the principle of natural selection shadowed forth, but how little Aristotle fully comprehended the principle, is shown by his remarks on the formation of the teeth.”

Even though Darwin did not think Aristotle ”fully comprehended” natural selection, what can be “fully comprehended” today is that the concept of natural selection pre-dated Darwin.

In this series, we will explore the difference between philosophy and science and specifically how the Scientific Revolution developed from use of the scientific method and how Darwin was eventually aligned between these opposing approaches to discovering the laws of nature – starting with Copernicus.

 Copernicus, by taking careful measurements to gather evidence, demonstrated that the Earth was not the center of the universe – rather, the Earth revolves around the sun. What made the key elemental difference was - the evidence. The evidence contradicted Aristotelian logic that had even crept into the Roman Catholic Church. The Scientific Revolution developed in concert along with a larger movement known as the Age of Enlightenment. In part, the movement was seeking to overthrow the Roman Catholic Church, which by the sixteenth century had even embraced Aristotle’s geocentric worldview.

 Driven to understand the universe as an act of the Creator, Copernicus wrote -  

 “The mechanisms of the universe, wrought for us by a supremely good and orderly Creator… the system best and most orderly artist of all framed for our sake.”

 Copernicus died in 1543 almost immediately after publishing his findings in the epochal book entitled On the Revolutions of the Celestial Spheres.

 While Copernicus’ escaped Roman Catholic Church rule, Galileo after confirming Copernicus’ findings was found guilty of “heresy” by the Inquisition in 1632. Thereafter, Galileo spent the last 10 years of his life under house arrest.

 Isaac Newton, after studying the evidence later in the eighteenth century, verified Copernicus’ and Galileo’s findings by using the scientific method. Newton is also known for discovering the laws of motion and gravity. When scientists at Britain’s Royal Society were asked in 2005 about who had the greater effect on the history of science, Newton or Albert Einstein – the vote went to Newton.

 The question is – what made the Scientific Revolution a revolution? The answer is – the system of reasoning. Aristotle logic was based on deductive reasoning. The Scientific Revolution was based on inductive reasoning.

 We will be exploring these differences in this series of blogs. What do you think is the difference between inductive reasoning and deductive reasoning? Is the difference important?
