Yan Zun and the Lines of Dao: Reading Daodejing Chapter 42 Through Laozi, Heshang Gong, and Wang Bi

This study restores the late Western Han thinker Yan Zun to his rightful place in the history of Daoist thought. Despite the deep influence of his Laozi zhigui, its fractured transmission has led to modern neglect. This paper illuminates Yan Zun’s overlooked philosophy through a comparative analysis of four readings of Daodejing Chapter 42, a passage famous for its generative ambiguity. It juxtaposes Laozi’s Yangsheng phenomenology of co-presence, Heshang Gong’s Huang-Lao typological metaphysics, and Wang Bi’s Xuanxue radical metaphysics. Situated against this fully developed philosophical backdrop, Yan Zun’s commentary emerges as a sophisticated synthesis. By distinguishing between xu (emptiness) for an ontological non-being and wu (nothingness) for a generative cosmology, Yan Zun forges a unique “onto-cosmology.” He integrates a transcendent Dao as non-being with an immanent Dao as cosmogonic source, a creative tension his successors would later dissect. This analysis recovers Yan Zun both as a lost Daodejing commentator and as the architect of a pivotal, synthetic path in Daoist philosophy.
