Essential Questions and "I Can" Statements

Ethos

Ethos (Credibility), or ethical appeal, means convincing by the character of the author. We tend to believe people whom we respect. One of the central problems of argumentation is to project an impression to the reader that you are someone worth listening to, in other words making yourself as author into an authority on the subject of the paper, as well as someone who is likable and worthy of respect.

Ethos (Greek for 'character') refers to the trustworthiness or credibility of the writer or speaker. Ethos is often conveyed through tone and style of the message and through the way the writer or speaker refers to differing views. It can also be affected by the writer's reputation as it exists independently from the message--his or her expertise in the field, his or her previous record or integrity, and so forth. The impact of ethos is often called the argument's 'ethical appeal' or the 'appeal from credibility.' 

Pathos

Pathos (Emotional) means persuading by appealing to the reader's emotions. We can look at texts ranging from classic essays to contemporary advertisements to see how pathos, emotional appeals, are used to persuade. Language choice affects the audience's emotional response, and emotional appeal can effectively be used to enhance an argument.

[P]athos (Greek for 'suffering' or 'experience') is often associated with emotional appeal. But a better equivalent might be 'appeal to the audience's sympathies and imagination.' An appeal to pathos causes an audience not just to respond emotionally but to identify with the writer's point of view--to feel what the writer feels. In this sense, pathos evokes a meaning implicit in the verb 'to suffer'--to feel pain imaginatively.... Perhaps the most common way of conveying a pathetic appeal is through narrative or story, which can turn the abstractions of logic into something palpable and present. The values, beliefs, and understandings of the writer are implicit in the story and conveyed imaginatively to the reader. Pathos thus refers to both the emotional and the imaginative impact of the message on an audience, the power with which the writer's message moves the audience to decision or action.

The persuasive appeal of pathos is an appeal to an audience's sense of identity, their self-interest, their emotions. Many rhetoricians over the centuries have considered pathos the strongest of the appeals, though this view of persuasion is rarely mentioned without a lament about the power of emotion to sway the mind.

We naturally bend in the direction of what is advantageous to us, what serves our interests or the interests of any group we believe ourselves a part of. Even when advantage is not an issue, writers who belong to groups we identify with, or create groups we can belong to, often seem more compelling. We also naturally find more persuasive the speaker or writer who flatters us (especially indirectly) instead of insulting us. Thus skillful writers create a positive image in their words of the audience they are addressing, an image their actual readers can identify with. Who does not want to be the “sensible, caring person” the arguer describes? Especially powerful are devices that create an identity between the writer and reader so that the speaker almost seems to be the audience addressing itself.

The emotions also strongly assist, perhaps sometimes determine, persuasion. If, for example, a writer wants a reader to evaluate something negatively, she or he may try to arouse the reader's anger. Or to produce action to someone's benefit (e.q. to persuade us to make a charitable donation), an arguer may work on our pity.

Direct appeals to the reader to feel an emotion (e.q. “You should be crying now”) are rarely effective. Instead, creating an emotion with words usually requires recreating the scene or event that would in “real” circumstances arouse the emotion. Thus descriptions of painful or pleasant things work on the emotions. Or the arguer can work on the natural “trigger” of the emotion. If, for example, we usually feel anger at someone who, we believe, has received benefits without deserving them, then the arguer who wants to make us angry with someone will make a case that person was rewarded unfairly. 

Logos

Logos (Logical) means persuading by the use of reasoning. This will be the most important technique we will study, and Aristotle's favorite. We'll look at deductive and inductive reasoning, and discuss what makes an effective, persuasive reason to back up your claims. Giving reasons is the heart of argumentation, and cannot be emphasized enough. We'll study the types of support you can use to substantiate your thesis, and look at some of the common logical fallacies, in order to avoid them in your writing.

Logos (Greek for 'word') refers to the internal consistency of the message--the clarity of the claim, the logic of its reasons, and the effectiveness of its supporting evidence. The impact of logos on an audience is sometimes called the argument's logical appeal.

Finally, we come to the “argument” itself, the explicit reasons the arguer provides to support a position. There are many ways to describe the support provided in an argument, but a sample way to begin is to consider all the premises the author seems to supply. These can be scattered throughout the argument and expressed indirectly, so identifying premises is a judgment call in itself.

Next ask which of the premises are presented as objects of agreement that the arguer considers as given, elements of the argument taken for granted. Objects of agreement are basically either facts or values. Of course, the facts may not be facts and readers may not agree with the values assumed. Some of the premises will be supported further, but basically every argument has got to come down to certain objects of agreement that it presents as shared between arguer and audience.

You can also classify premises into the following categories. 1. Are they arguments based on definition? In other words, does the arguer make claims about the nature of things, about what terms mean, what features things have? 2. Does the arguer make analogies or comparisons? Does he or she cite parallel cases? 3. Are there appeals to cause and consequences? Arguing from consequence is especially common when policy issues are debated. 4. Does the arguer rely on testimony or authority by citing the received opinions of experts? Or does the author create some kind of authoritative reference group, citing public opinion on what most people think as support for his or her position?
