“The more a thing is perfect, the more it feels pleasure and pain.”

“Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.”

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

“the pain of losing a dollar is far more powerful than the pleasure of winning a dollar.”

“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.”

“For mysticism proper - as distinguished from philosophical theory or vague feeling or literary pleasure - is a practical thing, something more than a doctrine, a life.”
