period of Spring-autumn and Warring-states’ times， the utilitarian demand of states and inpiduals’ development put the primitive “Jen” spirit into a crisis， which shows the conflict between the value of “Jen” and the realistic utilitarian goal.

This is a contribution of profound significance to the development of Chinese and human civilization.
