Abstract: Agnes Heller constructs her feelings theory with the key point of “involvement”,and many times illustrates her idea that feelings,emotions,and feeling mean to be involved in something.Illustrated by Heller’s feelings theory phenomenologically,the concept of involvement develops in its connotation and extension.As an internalized section of human behavior and thinking,involvement for human plays a role in maintaining self-balance and keeping a relation with the world,which helps human being keep their own continuity and develop the organic society.With the nature of Marxism and meaning of practice,the concept of involvement enlarges Heller’s feelings theory,develops feelings theory in Western irrational philosophy,showing Heller’s reflection in human nature and destiny.
