“ Vain and weak men, among their inferiors, or those who dare not resist them, often affect to be ostentatiously passionate, and fancy that they show what is called, spirit in being so. ”
 Adam Smith, The Theory of Moral Sentiments (1759). copy citation

“and in such cases the meanness of the motive takes away all the nobleness of the restraint. Anger prompts to attack, and the indulgence of it seems sometimes to show a sort of courage and superiority to fear. The indulgence of anger is sometimes an object of vanity. That of fear never is. Vain and weak men, among their inferiors, or those who dare not resist them, often affect to be ostentatiously passionate, and fancy that they show what is called, spirit in being so. A bully tells many stories of his own insolence, which are not true, and imagines that he thereby renders himself, if not more amiable and respectable, at least more formidable to his audience. Modern manners, which, by favouring the practice of duelling, may be said, in some cases, to encourage private revenge, contribute, perhaps, a good deal to render, in modern times, the restraint of anger by fear still more contemptible than it might otherwise appear to be.” source
