This article discusses friendship and filial piety in Ming Neo-Confucianism, particularly the Yangming learning. I argue that the Yangming jianghui provided important social settings for elevating the value of friendship. True friendship was considered as a means for moral improvement, and to prevent the risk of moral subjectivism in the Yangming philosophy.
I also revisit the question of whether Ming Neo-Confucians did challenge the order of the five cardinal relationships by elevating friendship as the most important one. Through the investigation of filial piety in imperial culture and the Yangming learning, I emphasize that filial piety was not only the basis of socio-political order, but also the essence of the true self. The importance of friendship lies in its capacity to aid moral cultivation and to become a better self. It could never surpass that of filial piety. It remained a supplement to familial ethics.
