Evaluate Unstated or Suppressed Premises As Well As Stated Ones<\/b><\/span><\/h2>\r\n

An\u00a0unstated<\/b>\u00a0or\u00a0suppressed premise<\/b>\u00a0is assumed rather than voiced outright, but is nevertheless needed for an argument to work. Consider this highly unscientific poll conducted by a TV news station. \u201cWhich do you believe Senator Hillary Clinton is most \"Signout of touch with: illegal immigration, border security, or the American people?\u201d The pollster is operating as if it is unquestionable that Clinton is out of touch with\u00a0something<\/i>. In other words, the question\u00a0presupposes <\/b>that she is \u201cout of touch.\u201d However, this unstated premise is debatable once it is brought out into the open. Is she in fact out of touch at all? <\/span><\/p>\r\n

A listener or reader who is not alert to such\u00a0unstated<\/b>\u00a0or\u00a0suppressed premises<\/b>\u00a0is, without realizing it, agreeing to debate on the communicator\u2019s terms\u2014when those terms may be unfair. In fact, on more complex or serious issues it is often things people take for granted that may actually deserve the most critical scrutiny. For example, in the argument \u201cThis medication is labelled as totally natural, so it is safe for me to take it,\u201d the suppressed premise\u2014that \u201cnatural\u201d guarantees \u201csafe\u201d\u2014is not trivial and can certainly be challenged.<\/span><\/p>\r\n\r\n

Argument Diagramming<\/b><\/span><\/h2>\r\n

Besides recognizing the use of induction and deduction, you can use\u00a0diagramming<\/b>\u00a0or\u00a0outlining<\/b>\u00a0to develop an understanding of an argument\u2019s overall structure. Remember that an argument as defined here isn\u2019t a \"quarrel,\" but rather a group of statements, some of which, the premises, are offered in support for another, the conclusion. So the first order of business in analyzing an argument is to recognize what the main claim is\u2014the conclusion\u2014and what other claims are being used to support it\u2014the premises. This is much easier to do when the author\u00a0is explicit about the steps in the argument, where premise and conclusion \"indicator\" terms appear in the text as signposts.\u00a0<\/span><\/p>\r\n\r\n

\r\n

Words that introduce or signal an argument conclusion include\u00a0therefore<\/i>, so<\/i>,\u00a0we may conclude<\/i>\/infer<\/i>,\u00a0thus<\/i>, and\u00a0consequently<\/i>. Words that introduce or signal argument premises include\u00a0it follows that<\/i>,\u00a0implies that,\u00a0as a result<\/i>,\u00a0because<\/i>\u00a0(non-causal meaning),\u00a0since, for the reason that<\/i>,\u00a0for, and<\/i>.[footnote]and<\/i><\/b>\u00a0often signals the introduction of a further premise, as in \"You should believe Z\u00a0because<\/i><\/b>\u00a0reason 1\u00a0and<\/i><\/b>\u00a0reason 2.\"[\/footnote]<\/span><\/p>\r\n\r\n<\/div>\r\n

When you are diagramming or outlining an argument, if the \u201cflow\u201d of an argument from premises to conclusion isn\u2019t readily apparent, then remember to use the above indicator terms to help you decide which claim is the conclusion and which claims are the premises. Using the indicator terms is particularly helpful because a conclusion may be stated first, last, or anywhere in between. People do all three when they write or talk in real life, so we cannot tell whether a statement is a conclusion simply by where it is positioned in the argument.<\/span><\/p>\r\n\r\n

The Purpose Behind\u00a0Diagramming an Argument<\/b><\/span><\/h3>\r\n

Diagramming or mapping someone else\u2019s argument serves a double purpose. First, the process helps you clearly see just what the other person is saying. It helps you identify the logical structure of the argument, which is necessary if you are to assess the strengths and weaknesses of the argument in order to know whether or not to accept it. Second, you develop skills of analysis that you will need in order to organize and present arguments in support of a position that\u00a0you\u00a0<\/i>may want to take on some question or issue.<\/span><\/p>\r\n\r\n

Steps in\u00a0Diagramming an Argument<\/b><\/span><\/h3>\r\n

Here are the basic moves that are required in order to create a clear diagram or outline of an argument.<\/span><\/p>\r\n\r\n

    \r\n \t
  1. Identify all the claims made by the author. Since a sentence can contain multiple claims, rewrite statements so that you have one claim per sentence. Adopt some sort of numbering or labeling system for the claims.<\/span><\/li>\r\n \t
  2. Eliminate \u201cfluff.\u201d Ignore repetitions, assurances (assertions not backed by evidence or reasons), and information that is unrelated to the argument.<\/li>\r\n \t
  3. Identify which statements are premises and which statement is the main conclusion.<\/li>\r\n \t
  4. Recognize that there may be sub-conclusions in addition to a final or main conclusion. You may think of a sub-conclusion as the end point of a sub-argument nested inside the larger argument. Although the sub-conclusion is itself the conclusion of a nested argument, supported by premises, it also functions as a premise supporting the final or main conclusion.<\/li>\r\n \t
  5. Recognize that some premises are independent and others linked. If you were drawing or mapping the argument, you would be able to draw an arrow from an independent premise directly to the conclusion it supports. Linked premises, however, are multiple statements that must be combined to provide support for a conclusion. If you were drawing or mapping the argument, you would have to find some way to show that the linked premises as a group support the conclusion. You might use color coding, or underlining, or circling, or + signs\u2014some way to connect the linked premises before drawing\u00a0one<\/i><\/b>\u00a0arrow from the clustered premises to the conclusion they support.<\/li>\r\n<\/ol>\r\n

    Using the Argument's Paragraphing to Evaluate the Premises<\/h2>\r\n

    <\/b>An author must organize her material to guide the audience through her argument. One tool available to an author is the paragraph. The sentences clustered together in a paragraph should be tightly connected in terms of content. In the most common\u00a0form of paragraph, the clustered sentences collectively develop an idea explicitly stated in a topic sentence. The paragraphs themselves should be placed in an order that reflects some overall plan so that the paragraphs reveal the steps or stages of the argument.<\/span><\/p>\r\n

    \"slipsThe premises may be said to be key steps or stages in the argument. A well-constructed argument therefore may use each premise as a topic sentence for a paragraph. Additionally, a premise may serve as the guiding idea for a group of paragraphs, each developing a subtopic. For example, the premise, reached by induction, that \u201cCollege students overestimate the amount of binge drinking that is taking place\u201d might introduce a cluster of three paragraphs, each showing that the overestimation varies by subgroup\u2014with member of sororities, member of fraternities, and non-Greek populations arriving at different estimates.<\/span><\/p>\r\n

    Look to see whether the author has used paragraphing-by-premise to organize her argument and outline its structure for the audience. You should also ask yourself whether any paragraphs are missing. That is, as you consider what premises serve as the foundations of the argument, be alert for the suppressed ones, the premises that the author presupposes. These unacknowledged premises may be ones that the author hopes the audience will not notice or question. In your analysis call her on it by determining where a paragraph on that premise should have appeared in the argument.<\/span><\/p>\r\n\r\n

    The Similarity Between Conclusions and Thesis Statements<\/h3>\r\n

    When we talk about a paper, we usually talk about the paper\u2019s main claim as being its thesis statement. But of course a paper that just makes a claim or states an opinion but offers no supporting reasons or arguments isn\u2019t much of a paper. We would be bothered by reading an editorial in which someone stated a strong opinion on some public issue yet did nothing to justify that opinion.<\/span><\/p>\r\n

    When an author supports a thesis with reasons, then the thesis statement can be described as the conclusion of an argument, with the supporting reasons being that argument\u2019s premises. The argument now has a structure that can be outlined or diagrammed.<\/span><\/p>","rendered":"
