Joyce began his literary career with strong discontent with his social condition. Ulysses is Joyce's optimum work, which takes 3 Dublin characters' experience in one day as the main line to show the paralysation and crisis of the whole Western society, people's emptiness on their minds, loneliness on their feelings and labefaction on their spirits, also, it showed the inextricable perplexity. To treat the theme of inextricable perplexity, this paper is trying to set about the inextricable Catholic Church and identity problems, with the ideas of Alick West-the outstanding English Marxist literary critic of the 20th century.
