The Enlightenment changed Western attitudes by encouraging people to rely more on reason than on faith. Before the Enlightenment, people were more willing to simply take things on faith. They were willing to simply believe what people had always believed. With the Enlightenment, there came to be a much greater emphasis believing only those things that could be proven through reason. This tended to move people away from faith to some degree. It did this because it emphasized that human intellect and thinking were more important and more credible than faith was.
