  To this, the Mohists might respond that we should still practice equal care, because it is the way of the sage-kings and the intention of Heaven, the highest moral exemplar, and its practice produces great benefit for the world. The Mohists recognize no distinction between obligation and supererogation, and perhaps their religious beliefs convince them that the best life is one that most fully complies with Heaven’s desire that we care for and benefit others. Also, as the Zhuangzi passage  quoted earlier  attests, many Mohists particularly revered and emulated Yu, the most self-sacrificing and altruistic of the sage-kings.
