Ideological and political education is the primary content of China's spiritual civilization construction, and it is also one of the main ways to solve social contradictions and problems. Ideological and political education is both important and difficult to do, especially under the condition of market economy, China's ideological and political work is relatively weak and can not adapt to the development of modern society. There are many reasons for the ineffective ideological and political work, but one of the important reasons is that we have neglected personality education and cultivation for a long time. I believe that personality education is the basis of ideological and political education. Without this foundation, ideological and political education is like duckweed without roots, always drifting on the surface of people's thoughts and not going deep. The reasons are as follows: First, personality is the stable psychological basis for the formation of life values. People's values must be unified and stable, which requires a person's psychological process and personality form to be unified and stable. Otherwise, a divided personality can only produce the concept of division. Second, personality is the internal psychological basis for forming a specific world outlook and outlook on life. World outlook is the understanding of the world. Although the correct world outlook comes from the correct theoretical guidance and study, if there is no benign personality form as the internal psychological basis, it is difficult to instill external ideas. Third, personality is the main driving force to form a specific moral quality. Personality has the characteristics of quality. Therefore, once personality is formed, people have corresponding internal textures, and different textures will adapt to different moral tendencies. A benign personality is naturally easy to establish a benign moral quality. Of course, these basic functions of personality are not absolute, but often relative. At the same time, it also influences and transforms people's values, world outlook, outlook on life and moral consciousness.
