Moral behaviors, because of their seeming violation of the universal law of human behaviors, i.e., self-regard, are considered by both those who emphasize the importance of morality and those who stick to the significance of self-interest as basically incompatible with other wish-fulfilling behaviors. But according to Mencius, they are as desirable as, or even more desirable than, other wish-fulfilling behaviors, which he supported with two points-the desirability of the aim of moral behaviors and the desirability of sticking to moral principles-and thus found a solid ground for them in natural human motivations.
