It would not be because he wanted to improve his relations with the child's parents, nor because he wanted a good reputation among his friends and neighbors, nor because he disliked hearing the child cry.

Those who know how to develop the four potentials within themselves will take off like a fire or burst forth like a spring. Those who can fully develop them can protect the entire land while those unable to develop them cannot even take care of their parents. Gaozi said, ' 'Human nature is like whirling water.
Human nature is no more inclined to good or bad nor water is inclined to east or west'.
Goodness is to human nature like flowing downward is to water. There are no people who are not good and no water that does not flow downward.
