In discourse thou must attend to what is said,and in every movement thou must observe what is doing.
And in the one thou shouldst see immediately to what end it refers,
but in the other watch carefully what is the thing signified.
談話時必須傾聽所說的話,
行動時必須注意所做的事。
行動中要認真觀察行為會達到怎樣的結果;
談話中要用心把握所說話的含意。
---《沉思錄-我與自己的對話》
