“When we are overly concerned with what people think we will be controlled by the thoughts and opinions of other people.”

“As long as we continue to live as if we are what we do, what we have, and what other people think about us, we will remain filled with judgments, opinions, evaluations, and condemnations. We will remain addicted to putting people and things in their "right" place.”

“We speak not only to tell other people what we think, but to tell ourselves what we think. Speech is a part of thought.”

“We will gradually become indifferent to what goes on in the minds of other people when we acquire a knowledge of the superficial nature of their thoughts, the narrowness of their views and of the number of their errors. Whoever attaches a lot of value to the opinions of others pays them too much honor.”

“When we speak of power, we mean man's control over the minds and actions of other men. By political power we refer to the mutual relations of control among the holders of public authority and between the latter and the people at large.”

“We ought to be able to combine opposites: the love of goodness with indifference to other people's opinions, a liking for work with indifference to fame, concern for our health with indifference to life.”
