Exert One’s Heart / Mind to the Utmost
充分体认和发挥内心固有的善端。“尽心”是由孟子提出的一种道德修养方法。“尽心”需要发挥心所具有的思考能力，发现人心中固有的善端，并将其作为人之所以为人的本质特征，进而充分培养、发挥心中的善端，最终实现仁、义、礼、智的德行。心中的善端是天赋予人的本性，因此通过“尽心”就能够知晓人的本性，并通达于天。
“Exerting one’s mind to the utmost” means one should fully understand and extend one’s innate goodness. It is a way of moral cultivation advocated by Mencius. To do so, one needs to develop one’s capability of thinking, discover the goodness inherent in the mind and then fully nurture this innate human character, eventually realizing the moral qualities of benevolence, righteousness, rites and social norms, and wisdom.
