What is the meaning of the motto of Beijing Jiaotong University?

The motto of "Knowledge and Action" was firstly proposed by Wang Yangming, a philosopher in Ming Dynasty, who advocated "Seeking reason in my heart", i.e. "Knowledge and action are united", which is the motto of BJTU:

Knowledge: pursuit of thought; Action: way of life; Knowledge and Action: pursuit of one's thought and his way of life

BJTU has taken "Knowledge and Action" as the motto of BJTU in hope that every student will strive to seek knowledge and reason and be able to combine learning and application of what they have learned in their own heart and use it in their own actions. It is hoped that every student of NJTU will strive for knowledge and reasoning in the school, and be able to combine learning with application, and realize what they have learned in their own hearts and use it for their own actions.
