This article intends to bring to light the adventures of Western Marxism in China in the 1980s. It focuses on the philosophical ideas raised and illuminates the views of reformist and orthodox Marxists in the polemic about Western Marxism. I argue that in early 1989 the debate about Western Marxism had escalated into a fundamental challenge to the official ideology-a challenge that came to a sudden halt with the Tiananmen crackdown on 4 June 1989 and the chilling effect this event had on ideological discussion in China.
