The romantic movement of the late 1700's and early 1800's can be summed up with one word--"sublime." The word sublime has to do with a sense of grandeur. The idea behind romantic literature had to do with a person's inner-experience which usually dealt with extreme emotions. Pure joy is juxtaposed with horror and terror. Romantics believed that in order to truly experience life, or to find truth in an individual's life-path, all extremes must be visited and analyzed. Heathcliff and Catherine's relationship encompasses both true love (and the joy found therein) and utter devastation of insurmountable obstacles. What other situation could be more sublime than finding your soul mate but not being able to live with him/her? The challenges faced by the two lovers are extreme on both the outside as well as the inside because it is observed in public and struggled with in their hearts and minds.
