What does it mean to say that we live in a world of persuasion? It means that we live among competing interests. Your roommate‟s need to study for an exam may take priority (优先) over pizza. Your instructor may have good reasons not to change your grade. And the object of your romantic/interest may have other choices. In such a world, persuasion is the art of getting others to give fair and favorable consideration to our points of view. When we persuade, we want to influence how others believe and behave. We may not always prevail — other points of view may be more persuasive, depending on the listener, the situation, and the merit of the case. But when we practice the art of persuasion, we try to ensure that our position receives the attention it deserves. Some people, however, object to the very idea of persuasion. They may regard it as an unwelcome interruption into their lives. Just the opposite, we believe that persuasion is unavoidable — to live is to persuade. Persuasion may be ethical (合乎道义的) or unethical, selfless or selfish, inspiring or degrading. Persuaders may enlighten our mind or prey on our vulnerability. Ethical persuasion, however, calls on sound reasoning and is sensitive to the feelings and needs of listeners. Such persuasion can help us apply the wisdom of the past to the decisions we now must make. Therefore, the most basic part of education is learning to resist the one kind of persuasion and to encourage and practice the other.
