Abstract: With the change of the principal contradiction in society, people attach more and more importance to the common prosperity of spiritual life. From the perspective of Marxist theory of humanity, it can be found that people’s needs promote the common prosperity of spiritual life. Realistic people and the masses are the main body of the common prosperity of spiritual life. The common prosperity of spiritual life and all-round human development are consistent. We can rely on people’s work practice to promote the common prosperity of the people’s spiritual life.
