《尉缭子·攻权》
如果不能以爱托使士卒悦服、士卒就不会为我所用；如果不能以威信使士卒畏成，士卒就不会听我指挥。
夫不爱说其心者，不我用也；不严畏其心者，不我举也。
If we cannot use love to make the ordinary soldiers submit willingly, the ordinary soldiers will not be of use to us; if we cannot use prestige to make the ordinary soldiers afraid, the ordinary soldiers will not listen to our commands.
