For Mozi, Heaven is the divine ruler, just as the Son of Heaven is the earthly ruler. Mozi believed that spirits and minor demons exist or at least rituals should be performed as if they did for social reasons, but their function is to carry out the will of Heaven, watching for evil-doers and punishing them. Mozi taught that Heaven loves all people equally and that each person should similarly love all human beings without distinguishing between his own relatives and those of others (Dubs, 1959-1960:163-172). Mozi criticized the Confucians of his own time for not following the teachings of Confucius. In Mozi's Will of Heaven (天志), he writes:

Moreover, I know Heaven loves men dearly not without reason. Heaven ordered the sun, the moon, and the stars to enlighten and guide them. Heaven ordained the four seasons, Spring, Autumn, Winter, and Summer, to regulate them. Heaven sent down snow, frost, rain, and dew to grow the five grains and flax and silk that so the people could use and enjoy them. Heaven established the hills and rivers, ravines and valleys, and arranged many things to minister to man's good or bring him evil. He appointed the dukes and lords to reward the virtuous and punish the wicked, and to gather metal and wood, birds and beasts, and to engage in cultivating the five grains and flax and silk to provide for the people's food and clothing. This has been so from antiquity to the present."
