劳动是人的类本质。劳动之所以能够把人从动物中提升出来，在于真善美因素于劳动中的积淀。劳动是人的类本质也意味着人是追求真善美的动物。正因为如此，人类社会系统就具有了自然系统所没有的主体性，从而使人类历史的发展既服从生产力发展的需要，又服从人的目的。这表明，建设一个现代化国家，必然包含塑造具有现代追求和相应能力的人的任务。 Labor is human nature. The reason why labor can lift people out of animals lies in the accumulation of factors of truth, goodness and beauty in labor. Labor is the essence of human beings also means that people are animal pursuit of truth, kindness and beauty. Because of this, the human social system has the subjectivity that natural systems do not have, so that the development of human history obeys the needs of the development of productive forces and obeys man’s purpose. This shows that the construction of a modernized nation necessarily involves the task of shaping a person with a modern pursuit and corresponding capabilities.
