Confucian scholars believed that nothing is possible without sincerity, which is the basic principle or law followed by humans and all things. It is a process in which humans and all things give full play to their inherent nature or essential properties. Sincerity is what enables them to exist and improve themselves, and it is an ideal state of both their interaction and integration. In terms of human activities, it is obvious that without sincerity, nothing can be accomplished. This notion stresses that sincerity is both real and fundamental, that humans have subjectivity, and that with sincerity, they can achieve unity with the outer world.

Sincerity is what makes oneself whole, and its way shows how one conducts oneself. Sincerity makes things happen and deliver outcomes. Without sincerity, there is nothing. For this reason, a man of virtue reveres sincerity. Sincerity not only makes oneself whole but also makes other people and creatures whole. Making oneself whole is a virtue; making others whole is vision. Virtue and vision are naturally born, and they are fundamental to achieving unity between oneself and the outer world. The Book of Rites

Sincerity makes things happen and delivers outcomes. Without sincerity, there is nothing. Things are the same as undertakings. Without sincerity, nothing can be achieved. The New Tang History
