Classicism was based on the idea that nature and human nature could be understood by reason and thought. Classicist believed that nature was, a self-contained machine, like a watch, whose laws of operation could be rationally understood. Romanticists viewed nature as mysterious and ever changing. Romantic writes believed that nature is an ever changing living organism, whose laws we will never fully understand.

Classicists thought that it was literature's function to show the everyday values of humanity and the laws of human existence. Their idea was that classicism upheld tradition, often to the point of resisting change, because tradition seemed a reliable testing ground for those laws. As for the Romantics, they wrote about how man has no boundaries and endless possibilities. The Romantics stressed the human potential for social progress and spiritual growth.
