“There is nothing in the world more difficult than candor, and nothing easier than flattery. If there is a hundredth of a fraction of a false note to candor, it immediately produces dissonance, and as a result, exposure. But in flattery, even if everything is false down to the last note, it is still pleasant, and people will listen not without pleasure; with coarse pleasure, perhaps, but pleasure nevertheless.”

“Nothing in this world is harder than speaking the truth, nothing easier than flattery.”

“Nothing brings more pain than too much pleasure; nothing more bondage than too much liberty.”

“I came to consider the instinct as nothing more than the "motor aspect of pleasure."”

“Flattery is nothing but attention without intention.”

“Conversation, to take another example, is one of the common pleasures of life, but not all conversation is pleasurable. The stutterer finds talking painful, and the listener is equally pained. Persons who are inhibited in expressing feeling are not good conversationalists. Nothing is more boring than to listen to a person talk in a monotone without feeling. We enjoy a conversation when there is a communication of feeling. We have pleasure in expressing our feelings, and we respond pleasurably to another person's expression of feeling. The voice, like the body, is a medium through which feeling flows, and when this flow occurs in an easy and rhythmic manner, it is a pleasure both to the speaker and listener.”
