Confucius' religious thought summarized and utilized existing historical and cultural achievements. He strove to bring problems concerning traditional religious ideas such as destiny, the spirits, ritual propriety and faith into the realm of the rational. He sought to unearth the elements of human reason contained within these and to highlight the sublime and sacred in actual human society. He established a system of religious humanism that incorporated views on edification, faith, destiny, the ghosts and spirits and self-cultivation. Using a dialectic based on the mean, he established a spiritual mindset comprising rational faith, a this-worldly transcendence and a sacredness grounded in the human that led ancient Chinese religious thinking in a unique direction.
