Raymond W.K. Lau, PhD, was Professor of Sociology at the Hong Kong Metropolitan University until retirement in 2017; he is currently Visiting Senior Research Fellow at the Hong Kong Shue Yan University. He has published primary research on the philosophies of Xunzi, Laozi, and Zhuangzi. In Intellectual Developments in Greece and China: Contingency, Institutionalization and Path Dependency (2020), he formulated a theoretical-methodological framework for analyzing intellectual development on a non-essentialist basis, which also underpins the present work. His research into the Needham Question is an extension from that previous work. He is a co-editor and contributor to the volume titled Multicultural Exchanges in the Making of Modern Science: Needham’s Dialogical Vision (Palgrave Macmillan, 2024).
