Speech and Emotion by Friedrich Wilhelm Nietzsche

That speech is not given to us to communicate our emotions may be seen from the fact that all simple men are ashamed to seek for words to express their deeper feelings. These feelings are expressed only in actions, and even here such men blush if others seem to divine their motives. After all, among poets, to whom God generally denies this shame, the more noble are more monosyllabic in the language of emotion, and evince a certain constraint: whereas the real poets of emotion are for the most part shameless in practical life.
