Abstract: Encountering the subversion of dominant values, the intellectuals in the May 4th Period were compelled to seek for new faith in order to settle the soul. Moreover, the twins of “faith and doubt” brought about a seesaw struggle in the mind of each intellectual in this period. Zhi Qian-zhi was famous for his romantic, unruly and even maniac image during this period. His sensitiveness of religion forced him to seek for the transcendence of life. As an intellectual in the May 4th Period, the tension of “doubt and faith” made him painfully move back and forth between revolution and suicide, and hope and despair. The thesis is aimed to unfold the complicated and rich spiritual world of intellectuals in the May 4th Period by analyzing Zhu Qian-zhi.
