Mencius defines benevolence as humanity’s essential nature. Integrated together, benevolence and humanity form the supreme Dao. This core idea anchors his theory of inherent goodness, holding that cultivating inner benevolence lets people grasp the universal truth.
Mencius outlines core Confucian cultivation: fully expanding one’s mind reveals inherent good nature, which lets one understand Heaven. Guarding the mind and nurturing nature serves Heaven; steady self-cultivation amid varying life spans fulfills one’s destined mission.
Mencius uses fish and bear paws to illustrate choosing righteousness over life. All people possess this innate moral dignity, seen in starving folks rejecting insulting food. Many lose their original conscience by accepting lavish wealth against moral principles.
Mencius explains the king’s lack of wisdom with the “one sun, ten cold” metaphor. He adds Yi Qiu’s chess fable: two pupils differ not in talent but focus, proving consistent positive influence and full concentration are vital for nurturing innate goodness.
Mencius uses barren Mount Niu as a metaphor: innate moral conscience is gradually worn away by daily desires and bad deeds. Morning pure inner vitality fades without constant nurture, urging people to guard their good hearts actively.
Mencius argues environment twists innate good nature, using barley and sensory analogies. Humans share universal tastes, hearing and sight; likewise all minds delight in principle and righteousness, proving sages and ordinary people share identical moral endowment.
