人心原本是快乐的。这是王阳明弟子、泰州学派创立者王艮提出的观点。王艮认为人生下来就是快乐的，而很多人之所以不快乐，就是因为这个真乐本体被一己私欲所蒙蔽，而要破除这种束缚，就要用自己内心的良知来觉察和约束私欲，通过良知的修炼沉潜消除私欲，本体之乐就会回归，从而达到快乐之境。

Joy Is Original of Man's

Heart and Mind

This concept was proposed by Wang Gen, a student of Wang Yangming and founder of the Taizhou School of the Mind. For Wang Gen, all humans are born joyful. The reason why many are not happy is that their true and innate joy is blinded by their selfish desires. To break away from this constraint, they must use their inner conscience to detect their selfish desires. By the innate knowledge of good, these selfish desires can be eliminated, thus allowing the return of true and innate joy and the acquisition of a joyful disposition.

引例

人心本自乐，自将私欲缚。私欲一萌时，良知还自觉。一觉便消除，人心依旧乐。（王艮《乐学歌》）（人心原本是快乐的，个人欲望太盛就会蒙蔽本心。当一己私欲萌发的时候，内心的良知可以自我觉察，通过良知的觉察和调控可以消除私欲，让人心重回到快乐的状态。）

Joy is original of man's heart and mind and becomes blinded only by one's selfish desires. When these selfish desires emerge, one's inner conscience can still detect them by itself and use its conscientious reflection to uproot them, thus retaining a joyous heart. (Wang Gen: A Song of the Joy of Learning)
