1961, Address at the University of Washington
“self-development is a higher duty than self-sacrifice.”
Variant translation: "Before joy, anger, sadness and happiness are expressed, they are called the inner self; when they are expressed to the proper degree, they are called harmony. The inner self is the correct foundation of the world, and harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad things are nourished and grow thereby."
As translated by Lin Yutang in The Importance of Living (1937), pp. 143–144
