Happiness,as the eternal value pursuit of mankind,is also the direction that Marx devoted his life to pursue.In order to achieve human happiness,Marx started from the"complete"reality of the individual,and dispelled the abstract and formal discussion of happiness in previous philosophy.at the same time,Marx based on the"labor-leisure"patterns of human existence and development,took care of people’s happiness and the return of subjective value.Therefore,Marx took"people’s orientation"as the logical kernel of happiness research;took the happiness implication of"labor-leisure"as logical basis;criticized the dual alienation of"labor-leisure"in capitalist society,and realized the double reversion of"labor-leisure"into logical construction.Marx emphasized that alienated labor is the root cause of labor misfortune,leisure alienation is a metaphor that restricts the acquisition of happiness experience in alienated labor.Only by achieving the unity of shared decent work and shared leisure,can truly realize the return of human subjectivity and become the existence of happiness.
