Abstract
Xunzi discussed solidarity in two ways, that is, distancing through ritual and unifying through music. Therefore, it can be said that the solidarity is achieved between distancing from and closing to others. In this paper, I try to find an answer to the question how the solidarity is possible in Xunzi's ideas. Xunzi emphasized that individuals are different in discussing the solidarity through the rituals. When they accept the standard for differentiating themselves, they can be unified. In other words, they can form the solidarity with others through the common moral symbol of rituals. However, it is very hard to expect they have common belief or ideas by means of the symbol. Therefore, Xunzi tried to complement the imperfect solidarity of morality by means of music. The solidarity through music is based on human emotions. We can feel enjoyable when we listen to music or dance with others. The emotion of enjoyment is one of the representative phenomena when we reach to the state of flow claimed by Mihaly Csikszentmihalyi. In this state, we feel the breakdown of boundary between us and the others. The emotional entrainment or the breakdown of the boundary does not necessarily mean that we form the solidarity with them. However, people participating in the rituals interpret the symbol of morality in different ways, but can feel oneness with the others just by participating in the same activity or dancing with them by the same rhythm. People who share the same activity have higher chances of forming the common belief. Therefore, the solidarity by music is the source of the one by rituals, and music can make a stronger sense of solidarity than rituals among people.
