1700-1820: Subjects I've learned about once more

Upon reading this introduction to the new era we read in class, I was surprised as to notice the subject matter we'll be getting into that I've not been taught in a while: the Enlightenment Period. Last I heard about this particular period in history was in high school, but I don't remember much about it apart from the idea of "new ideals". I was most intrigued to re-learn of the different ideals introduced during the time such as Deism, which I do not believe in, I just found it very interesting to have revisited ideas that I remember learning about. Little did I realize, though, that one of the biggest ideas introduced around this time was psychology -- a subject that very much intrigues me. The reason I found it so intriguing was because, at the moment, I anticipate that there will be more of a "psychological factor" in our readings (meaning readings that understand how people work). Far as I know, it may be one of the more interesting periods that we read about.
