FAITH AND REASON IN THE 17TH AND 18TH CENTURIES During the 17th and 18th centuries many ideas were put forward that ended up changing people's faith and reason. These new ideas challenged man's conception of the universe and his place in it. They challenged a person's point of view and also challenged the belief of the economy. There were many scientists and philosophers during this time period, Francis Bacon, René Descartes, John Locke, Nicolaus Copernicus, Isaac Newton, and Adam Smith, to name a few. All these people contributed to the change in people's faith and their reason. They were given new ideas and a new way of looking at life. Sir Francis Bacon (1561-1626) helped change people's minds. People believed that most of the truth had already been discovered. And those who "devoted themselves to the invention of the arts did nothing more than cast an eye or two on facts, examples and experience..."1. Bacon believed that these people never really cared about the facts. He believed that these people feared that movements and changes in philosophy would end in attacks on religion. They were also afraid that seeking the truth could be dangerous for them. But he believed "that all knowledge comes from sensory experience, observation and experimentation"2 and that there was still much to discover. Bacon believed that we are servants and interpreters of nature. What we know and what we do is only what we have observed of the order of nature in fact or in thought.3 René Descartes contributed to changing the idea of ​​how the person is looked at. He also invented a way of deductive reasoning. He believed that “human beings were endowed by God with the ability to reason and that God acted as guarantor of the correctness of clear ideas.”4 Descartes believed in “I think, therefore I am.”5 He believed that everyone has the ability to reason. ability to think with one's own head. Descartes provided a method of deductive reasoning, a way to arrive at an answer. The first step in this process is to not accept anything as true unless it was clearly true. The second step is to divide each difficulty into as many parts as possible. The third step is to bring thoughts into order. And the final step is to write detailed reports to ensure that nothing is omitted.6 This method has had influence until the past
