Based on the introduction of “The Enlightenment in Europe and the Americas”, the author has compared the Enlightenment period and modern period. In Enlightenment era, a time period when  the ideas formed physically and mentally. In physical, they started study the body structure of human, in another word the biology has began to develop, and the improvement of the science. That was the time period when people doubt about the existence of god, and mention that kings and queens were human beings instead of sons and daughters of god, or the ones blessed by god. Those royal families were just like them a regular human being but with a higher class position. The thoughts and highness toward royals has changed, that’s why two hundreds years later, they overtake the kings, for example French Revolution. If the royals continued the ideas of that’s they were sons of god, they might not overtake kings due to respect of god. However, by overtake the royals or leave royals away, people had gained a lot freedom; for instance, in America, the first amendment gave people in America the right to speak up. We as modern day people, are able to gossip about royals, governor, and so on. We don’t have any limit on communicating about any people. Especially, people behind the scene, they can say however they want without any worries. Since no one know who they are behind the scene. Modern society is a community allows people to speak up for themselves and others, but the Enlightenment the key that open up the door for freedom of the speech.
