The paper mainly analyzes the hypocrisy of Hester Prynne, the heroine of the famous novel, The Scarlet Letter. Hester was punished because she was found guilty of adultery. She would wear the letter “A” forever, she knew the meaning of the letter “ A”, she believed that it wasn’t punishment, as she couldn’t rebel in public, so she kept silence, she never raised her head to greet other people, if they greeted her, she laid her finger on the scarlet letter and walked away. The letter “A” was artistically done in fine red cloth surrounded by rich gold thread that wasn’t in accord with her clothes. As a rebel to the moral, she often thought about the role of a woman in the society. She thought that the system of society must be destroyed and built again long ago, yet she seemed to be always obedient and did so many good things to help others. But under the cover of it, the pride, sneer and rebellion were hidden. She hated the letter “A”, but wearing it all the time. Some other actions and thoughts of Hester putting her deep-going thoughts and her seeming obedience together, leads readers to think of her hypocrisy. The difference between her real and disguised aspect proved her hypocrisy.
