Mencius 6A.7

Mencius said, 'In good years the children of the people are most of them good, while in bad years the most of them abandon themselves to evil. It is not owing to any difference of their natural powers conferred by Heaven that they are thus different. The abandonment is owing to the circumstances through which they allow their minds to be ensnared and drowned in evil. There now is barley. Let it be sown and covered up; the ground being the same, and the time of sowing likewise the same, it grows rapidly up, and, when the full time is come, it is all found to be ripe. Although there may be inequalities of produce, that is owing to the difference of the soil, as rich or poor, to the unequal nourishment afforded by the rains and dews, and to the different ways in which man has performed his business in reference to it. Thus all things which are the same in kind are like to one another; why should we doubt in regard to man, as if he were a solitary exception to this? The sage and we are the same in kind. In accordance with this the scholar Long said, "If a man make hempen sandals without knowing the size of people's feet, yet I know that he will not make them like baskets." Sandals are all like one another, because all men's feet are like one another. So with the mouth and flavours - all mouths have the same relishes. Yi Ya only apprehended before me what my mouth relishes. Suppose that his mouth in its relish for flavours differed from that of other men, as is the case with dogs or horses which are not the same in kind with us, why should all men be found following Yi Ya in their relishes? In the matter of tastes all the people model themselves after Yi Ya; that is, the mouths of all men are like one another. And so also it is with the ear. In the matter of sounds, the whole people model themselves after the music-master Kuang; that is, the ears of all men are like one another. And so also it is with the eye. In the case of Zi Du, there is no man but would recognise that he was beautiful. Any one who would not recognise the beauty of Zi Du must have no eyes. Therefore I say, Men's mouths agree in having the same relishes; their ears agree in enjoying the same sounds; their eyes agree in recognising the same beauty - shall their minds alone be without that which the similarly approve? What is it then of which they similarly approve? It is, I say, the principles of our nature, and the determinations of righteousness. The sages only apprehended before me that of which my mind approves along with other men. Therefore the principles of our nature and the determinations of righteousness are agreeable to my mind, just as the flesh of grass and grain-fed animals is agreeable to my mouth.'
