Water indeed will flow indifferently to the east or west, but will it flow indifferently up or down? The tendency of our nature to good is like the tendency of water to flow downwards. There are none but have this tendency to good, just as all water flows downward.
MenciusWhen I say that all men have the mind which cannot bear to see the suffering of others, my meaning is illustrated this way: when two men suddenly see a child about to fall into a well, they all have a feeling of alarm and distress, not to gain friendship with the child's parents, nor to seek the praise of their neighbors and friends. From such a case, we see that a man without the feeling of commiseration is not a man. The feeling of commiseration is the beginning of humanity.
Mencius
