This article explores the relationship between the transformation of idolatry and the democratization of China in the past 100 years. It first proposes to examine idolatry in term of three sets of dichotomous concepts, mysticism versus mundanism, elitism versus commonerism, and asceticism versus hedonism. It then classifies idolatry into five different types: religious idolatry, ethnic idolatry, sage/luminary idolatry, recreational idolatry, and grass-roots idolatry. It also classifies the transformation of idolatry into five distinctive periods: immature diversification period, relative unification period, absolute unification period, exploratory diversification period, and mature diversification period. In the conclusion, the authors summarise the transformation of idolatry in China in term of three democratic trends: moving from immature diversification to mature diversification, moving from irrationality to rationality, and moving from blind identification with Western values to formation of independent judgments.
