“One must have nothing to do with the partiality of the individual, passionate self in order to raise oneself to the universality of the rational self.”

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

The Moon Is a Harsh Mistress (1966)
Context: A rational anarchist believes that concepts, such as "state" and "society" and "government" have no existence save as physically exemplified in the acts of self-responsible individuals. He believes that it is impossible to shift blame, share blame, distribute blame... as blame, guilt, responsibility are matters taking place inside human beings singly and nowhere else. But being rational, he knows that not all individuals hold his evaluations, so he tries to live perfectly in an imperfect world... aware that his efforts will be less than perfect yet undismayed by self-knowledge of self-failure.

1950s, Conquering Self-centeredness (1957)
Context: Now one will inevitably raise the question: How then do we conquer self-centeredness? How do we get away from this thing that we call self-centeredness? How can we live in this universe with a balance and with a type of perspective that keeps us going smoothly and we are not too absorbed in self? How do we do it?
