The world turned upside down for people who lived during the Scientific Revolution and the Enlightenment.
Things humans had believed for centuries were proven false. New information and new ideas constantly took the place of old ideas. It was exciting and upsetting. These new ideas changed people’s thoughts about the world in three major ways. The first was a new belief in progress, or the idea that things can change for the better. The second was a more secular, or nonreligious, view of the world. The third was a far-ranging belief in the importance of the individual. These three big ideas took hold as more people became educated and learned about the ideas of the Enlightenment’s big thinkers.
