In our life, there always are certain principles that we stick to. As Emily wrote in her poem, “the soul selects her own society, then shuts the Door”, those principles are unchallengeable. For Jane, this principle is her understanding of marriage. When Jane realized that she fell in love with Mr. Rochestor, she disapproved the potential marriage between Rochester and Blanche since they seemed don’t love each other. When she got engaged and people around her showed disrespect toward this unequal marriage, she insisted that marriage is the bond in the basis of love instead of wealth and class. Jane stuck to her principle when St. John asked her to marry him. Following the call from her soul, Jane turns back to the person she loved and married Rochester. From the way Jane deal with her marriage, we can observe that she is as stubborn as a stone.
