His main research project is a multivolume work in Confucian ethics that started in 1988. The goal is to start with close textual studies of early and later Confucian thought, and then transition to a primarily philosophical study of Confucian ethics, with close attention to the methodological issues involved. The first volume, Mencius and Early Chinese Thought, was published by Stanford University Press in 1997. A manuscript of the second volume, Zhu Xi and Later Confucian Thought (tentative title), has been completed and is currently under revision. The third volume, From Philology to Philosophy (tentative title), is close to completion and will focus on methodological issues in the transition from textual studies to philosophical explorations. It is anticipated that the final manuscripts of both volumes will be completed by 2018, after which additional volumes will follow.
