Critical theorists have argued that the concept of Enlightenment is paradoxical. While it designates the liberation from superstition through the use of reason, Enlightenment also sets up new forms of superstition. This article focuses on Gan Yang's and Wang Hui's rereading of the dynamic processes of Enlightenment in China and in Europe. It argues for a transcultural perspective on Enlightenment's tendency to give rise to a deformation of reason. Only if the culturally varying forms of reason and unreason in Europe as well as China are being reflected might it be possible to continue pursuing the self‐critical project of Enlightenment at a global level.
