《孟子·告子章句上·第十五节》
孟子说： 人的耳朵眼睛等器官不会思考，所以会被外物蒙蔽，他们一接触外物，就只能被外物所引诱。
曰： 耳目之官不思，而蔽于物，物交物，则引之而已矣。
Mencius said: The ear and the eye are the servants of the mind and will receive the direction of the mind. If the mind of the superior man be great, his ear and eye will be great; if his mind be small, his ear and eye will be small.
