Mou Zongsan held that "beauty is the superfluous brilliance of gasification", which means that beauty is the brilliance of the Yin and Yang Qi in the universe. In short, beauty is the brilliance of truth and goodness, which can be seen in the intuition of wisdom. On the basis of Mencius's thought of "brilliance of fullness", Mou Zongsan's theory transcended the theories of Immanuel Kant and Martin Heidegger. Immanuel Kant saw beauty as a bridge between truth and good, while Martin Heidegger saw beauty as the manifestation of truth. Mou Zongsan's definition of beauty was the separate beauty, based on the Confucian realm of unity of truth, goodness and beauty, with a strong moral metaphysics color. This embodies Mou Zongsan's grand wish to revive confucianism and realize Yuan Religion.
