Henrik Ibsen’s Hedda Gabler highlights the conflict between the aesthetic and the ethical.This thesis tries to use the theory of art and moral by John Ruskin,a famous British writer and art critic,to make a comparative study of Hedda’s“aesthetic”way of viewing beauty and Thea’s“theoretic”way of appreciating beauty,pointing out that only viewing beauty with morality,people can lead a healthy life.The“aesthetic”way of ignoring morality and seeking only sensual pleasure will eventually do harm to people.
