At the end of the eighteenth century and the beginning of the nineteenth, when Austen was living and producing her work, the romantic era was on the rise. "Pride and Prejudice" reveals this in such quotes as: “Vanity and pride are different things, though the words are often used synonymously. A person may be proud without being vain. Pride relates more to our opinion of ourselves, vanity to what we would have others think of us." Interest in human emotions, human character traits, feelings, and the like is a feature of romanticism. Another nice, short quotation reveals the same tendency in P & P: “Angry people are not always wise.” Anger and love, passion and fear are romantic things: “We are all fools in love”, Austen wrote.
But the work shows tendencies of realism, too, and Austen has become celebrated in part because she was able to leap beyond "definitional boundaries" separating one tendency from the next. She treated everyday people in everyday circumstances, as realists did, and she even commented on the everyday and our human inability to make it precise, all too often: “I cannot fix on the hour, or the spot, or the look or the words, which laid the foundation. It is too long ago. I was in the middle before I knew that I had begun.”
In short, P &P offers aspects of what has been called social realism, a genuine view of a society that the author knew well enough to write about accurately, and features of the romantic, the emotional, the sensitive.
