This book is a comparative study of the Anglican Bishop Joseph Butlers and Neo-Confucianist Wang Yangmings ethical enterprise. It first analyses, within their respective historical context, the two thinkers overarching worldviews and their seminal conception of conscience / liang-chih as a person's supreme moral guide. The English bishop and the Chinese philosopher-military general are then brought into dialogue by way of a comparing and contrasting of their distinct religious-philosophical traditions. In addition, Butler and Wang will be placed in a hypothetical encounter to explore how they, and by proxy Christianity and Confucianism, would critically appraise each others spiritual and sociopolitical endeavor. The end purpose of this study is to enhance our perception of the intriguing similarities and complex differences that exist between these two Axial Age civilizations. The author argues that dissonances notwithstanding, Butler and Wang share core values, consonances that could and should set the tone for an amiable Christian-Confucian co-existence.
