The Scientific Revolution, challenging then-contemporary beliefs, invoked lasting cultural changes in the Western world. Explore the effects of challenging particular ~'truths,~' religion, superstitions, and the humanity-centric view of the universe. Updated: 09/27/2021

Effects of the Scientific Revolution

Sometimes small events can have a big impact in unexpected places. For example, when the Scottish scientist Alexander Fleming began working on the chemistry of bread molds in the 1920s, he certainly did not set out to discover penicillin. Regardless, his 1928 discovery sparked the growth and use of antibiotics throughout the 20th century, likely saving millions of lives as a result.

Similarly, the scientists and philosophers of the Scientific Revolution did not set out to change the world; individually, they worked on their own problems in their own fields. However, all challenged traditional views of the world and fostered a new way of thinking that relied on empiricism and skepticism rather than accepted, fundamental truths - a development which changed the world forever.

Truths Challenged

The increased emphasis placed on experimentation and empirical knowledge during the Scientific Revolution caused many philosophers and scientists to rethink the very nature of knowledge itself. Skepticism among these groups of thinkers grew over Early Modern society's view of the world and the accepted truths on which it was based.

Rather than accepting knowledge based on revealed truths, those who espoused the principles of the Scientific Revolution believed that truth and fact lay through firsthand observation and experimentation. For example, the philosopher René Descartes famously took these skeptical views to their theoretical limit, questioning even his own existence. He ceased his own skepticism only through realizing that the very act of thinking about his own existence proved his existence.

Religion Challenged

This new basis for knowledge and findings made by the Revolution's astronomers naturally challenged the very foundations of the revealed truths of the Christian church. For example, the work of Copernicus and Kepler displaced Earth from the center of the universe, which inherently questioned the church's view that Earth and humanity, in particular, was chosen by God and rightfully resided in the center of His universe.

Furthermore, the discovery of natural laws caused many philosophers to rethink the nature, or even existence, of God and his role in the universe. This was also challenged by some of the ideas forwarded by several philosophers that the universe's laws could be quantified mathematically. After all, if the world was governed entirely by natural laws, such as magnetism or gravity, there was little room left for the intervention of a divine actor. These notions led some to adopt Deism and the mechanistic universe adopted by the Frenchman René Descartes.

Descartes and others rejected the idea that God could intervene into the matters of man any time He wished, because it would upset the balance of the laws He had put in place Himself, and instead, it favored a God more akin to a watchmaker. In other words, Descartes and his followers believed God had created all of the natural laws and all of the matter in the universe in the distant past. God then started the universe without any plans to intervene, allowing the universe and its constituent parts, laws, and people to play themselves out.

These ideas challenged several central tenets of Early Modern Christianity, both Catholic and Protestant, and angered several church authorities throughout the 17th century. The Italian astronomer and champion of the telescope, Galileo Galilei, was imprisoned in 1633 by Pope Urban VIII. Although he was released only six months later, he continuously faced the prospect of imprisonment and house arrest for the remainder of his life. Indeed, it is commonly believed that Copernicus waited to publish his landmark 1543 work, On the Revolutions of the Heavenly Bodies, until he was near death so as to avoid retribution from religious officials.

It is important to note that although many of the Scientific Revolution's findings contradicted accepted church teachings, many of the scientists and astronomers of the age were religious men and were certainly not directly intending to attack common 17th-century theology. Galileo was a devout Catholic, and the very threat of excommunication by the pope caused Galileo to recant his statements eliciting his belief in the heliocentric, Copernican model.
