23 What Is Standard Argument Form?

A standard way of capturing the structure of an argument, or diagramming it, is by numbering the premises and conclusion.  For example, the following represents another way to arrange the littering argument:

1. Littering is harmful
2. Litter is dangerous to animals
3. Litter is dangerous to humans

This numbered list represents an argument that has been put into standard argument form.  A more precise definition of an argument now emerges, employing the vocabulary that is specific to academic and rhetorical arguments. An argument is a set of statements, some of which (the premises: statements 2 and 3 above) attempt to provide a reason for thinking that some other statement (the conclusion: statement 1) is true.

Recognizing arguments is essential to analysis and critical thinking; if you cannot distinguish between the details (the support) of a piece of writing and what those details are there to support (the argument), you will likely misunderstand what you are reading.  Additionally, studying how others make arguments can help you learn how to effectively create your own.

What Are Argument Indicators?

While mapping an argument in standard argument form can be a good way to figure out and formulate a thesis, identifying arguments by other writers is also important.  The best way to identify an argument is to ask whether a claim exists (in statement form) that a writer justifies by reasons (also in statement form). Other identifying markers of arguments are key words or phrases that are premise indicators or conclusion indicators. For example, recall the littering argument, reworded here into a single sentence (much like a thesis statement):

Littering is harmful because it is dangerous to both animals and humans.

The word “because” here is a premise indicator. That is, “because” indicates that what follows is a reason for thinking that littering is bad. Here is another example:

The student plagiarized since I found the exact same sentences on a website, and the website was published more than a year before the student wrote the paper.

In this example, the word “since” is a premise indicator because what follows is a statement that is clearly intended to be a reason for thinking that the student plagiarized (i.e., a premise). Notice that in these two cases, the premise indicators “because” and “since” are interchangeable: “because” could be used in place of “since” or “since” in the place of “because,” and the meaning of the sentences would have been the same.

Figure 3.3 “Common Premise Indicators”

In addition to premise indicators, there are also conclusion indicators. Conclusion indicators mark that what follows is the conclusion of an argument. For example,

Bob-the-arsonist has been dead for a year, so Bob-the-arsonist didn’t set the fire at the East Lansing Starbucks last week.

In this example, the word “so” is a conclusion indicator because what follows it is a statement that someone is trying to establish as true (i.e., a conclusion). Here is another example of a conclusion indicator:

A poll administered by Gallup (a respected polling company) showed candidate X to be substantially behind candidate Y with only a week left before the vote; therefore, candidate Y will probably not win the election.

In this example, the word “therefore” is a conclusion indicator because what follows it is a statement that someone is trying to establish as true (i.e., a conclusion). As before, in both of these cases, the conclusion indicators “so” and “therefore” are interchangeable: “So” could be used in place of “therefore” or “therefore” in the place of “so,” and the meaning of the sentences would have been the same.

What Constitutes Support?

To ensure that your argument is sound—that the premises for your conclusion are true—you must establish support.  The burden of proof, to borrow language from law, is on the one making an argument, not on the recipient of an argument.  If you wish to assert a claim, you must then also support it, and this support must be relevant, logical, and sufficient.

It is important to use the right kind of evidence, to use it effectively, and to have an appropriate amount of it.

• If, for example, your philosophy professor did not like that you used a survey of public opinion as your primary evidence in an ethics paper, you most likely used material that was not relevant to your topic.  Rather, you should find out what philosophers count as good evidence. Different fields of study involve types of evidence based on relevance to those fields.

 

• If your professor has put question marks by your thesis or has written, “It does not follow,” you likely have problems with logic.  Make sure it is clear how the parts of your argument logically fit together.

 

• If your instructor has told you that you need more analysis, suggested that you are “just listing” points or giving a “laundry list,” you likely have not included enough explanation for how a point connects to and supports your argument, which is another problem with logic, this time related to the warrants of your argument. You need to fully incorporate evidence into your argument. (See more on warrants immediately below.)

 

• If you see comments like “for example?,” “proof?,” “go deeper,” or “expand,” you may need more evidence.  In other words, the evidence you have is not yet sufficient.  One or two pieces of evidence will not be enough to prove your argument.  Similarly, multiple pieces of evidence that aren’t developed thoroughly would also be flawed, also insufficient. Would a lawyer go to trial with only one piece of evidence?  No, the lawyer would want to have as much evidence as possible from a variety of sources to make a viable case.  Similarly, a lawyer would fully develop evidence for a claim using explanation, facts, statistics, stories, experiences, research, details, and the like.

You will find more information about the different types of evidence, how to find them, and what makes them credible in Chapter 6, “Research.”  Logic will be covered later on in this chapter.

What Is the Warrant?

Above all, connect the evidence to the argument.  This connection is the warrant.  Evidence is not self-evident.  In other words, after introducing evidence into your writing, you must demonstrate why and how this evidence supports your argument. You must explain the significance of the evidence and its function in your paper. What turns a fact or piece of information into evidence is the connection it has with a larger claim or argument: Evidence is always evidence for or against something, and you have to make that link clear.

 

What Is a Counterargument?

Remember that arguments are multi-sided. As you brainstorm and prepare to present your idea and your support for it, consider other sides of the issue. These other sides are counterarguments. Make a list of counterarguments as you work through the writing process, and use them to build your case – to widen your idea to include a valid counterargument, to explain how a counterargument might be defeated, to illustrate how a counterargument may not withstand the scrutiny your research has uncovered, and/or to show that you are aware of and have taken into account other possibilities.

For example, you might choose the issue of declawing cats and set up your search with the question should I have my indoor cat declawed? Your research, interviews, surveys, personal experiences might yield several angles on this question: Yes, it will save your furniture and your arms and ankles. No, it causes psychological issues for the cat. No, if the cat should get outside, he will be without defense. As a writer, be prepared to address alternate arguments and to include them to the extent that it will illustrate your reasoning.

Almost anything claimed in a paper can be refuted or challenged. Opposing points of view and arguments exist in every debate. It is smart to anticipate possible objections to your arguments – and to do so will make your arguments stronger. Another term for a counterargument is antithesis (i.e., the opposition to a thesis). To find possible counterarguments (and keep in mind there can be many counterpoints to one claim), ask the following questions:

• Could someone draw a different conclusion from the facts or examples you present?
• Could a reader question any of your assumptions or claims?
• Could a reader offer a different explanation of an issue?
• Is there any evidence out there that could weaken your position?

If the answer to any of these questions is yes, the next set of questions can help you respond to these potential objections:

Is it possible to concede the point of the opposition, but then challenge that point’s importance/usefulness?

• Can you offer an explanation of why a reader should question a piece of evidence or consider a different point of view?
• Can you explain how your position responds to any contradicting evidence?
• Can you put forward a different interpretation of evidence?

It may not seem likely at first, but clearly recognizing and addressing different sides of the argument, the ones that are not your own, can make your argument and paper stronger. By addressing the antithesis of your argument essay, you are showing your readers that you have carefully considered the issue and accept that there are often other ways to view the same thing.

You can use signal phrases in your paper to alert readers that you are about to present an objection. Consider using one of these phrases–or ones like them–at the beginning of a paragraph:

• Researchers have challenged these claims with…
• Critics argue that this view…
• Some readers may point to…

What Are More Complex Argument Structures?

So far you have seen that an argument consists of a conclusion and a premise (typically more than one). However, often arguments and explanations have a more complex structure than just a few premises that directly support the conclusion. For example, consider the following argument:

No one living in Pompeii could have survived the eruption of Mt. Vesuvius. The reason is simple: The lava was flowing too fast, and there was nowhere to go to escape it in time. Therefore, this account of the eruption, which claims to have been written by an eyewitness living in Pompeii, was not actually written by an eyewitness.

The main conclusion of this argument—the statement that depends on other statements as evidence but doesn’t itself provide any evidence for other statements—is

A. This account of the eruption of Mt. Vesuvius was not actually written by an eyewitness.

However, the argument’s structure is more complex than simply having a couple of premises that provide evidence directly for the conclusion. Rather, some statements provide evidence directly for the main conclusion, but some premise statements support other premise statements which then support the conclusion.

To determine the structure of an argument, you must determine which statements support which, using premise and conclusion indicators to help. For example, the passage above contains the phrase, “the reason is…” which is a premise indicator, and it also contains the conclusion indicator, “therefore.” That conclusion indicator helps identify the main conclusion, but the more important element to see is that statement A does not itself provide evidence or support for any of the other statements in the argument, which is the clearest reason statement A is the main conclusion of the argument. The next questions to answer are these: Which statement most directly supports A? What most directly supports A is

B. No one living in Pompeii could have survived the eruption of Mt. Vesuvius.

However, there is also a reason offered in support of B. That reason is the following:

C. The lava from Mt. Vesuvius was flowing too fast, and there was nowhere for someone living in Pompeii to go to escape it in time.

So the main conclusion (A) is directly supported by B, and B is supported by C.  Since B acts as a premise for the main conclusion but is also itself the conclusion of further premises, B is classified as an intermediate conclusion. What you should recognize here is that one and the same statement can act as both a premise and a conclusion. Statement B is a premise that supports the main conclusion (A), but it is also itself a conclusion that follows from C. Here is how to put this complex argument into standard form (using numbers this time, as is typical for diagramming arguments):

1. The lava from Mt. Vesuvius was flowing too fast, and there was nowhere for someone living in Pompeii to go to escape it in time.
2. Therefore, no one living in Pompeii could have survived the eruption of Mt. Vesuvius. (from 1)
3. Therefore, this account of the eruption of Mt. Vesuvius was not actually written by an eyewitness. (from 2)

Notice that at the end of statement 2 is a written indicator in parentheses (from 1), and, likewise, at the end of statement 3 is another indicator (from 2). From 1 is a shorthand way of saying, “this statement follows logically from statement 1.” Use this convention as a way to keep track of an argument’s structure. It may also help to think about the structure of an argument spatially, as the figure below shows:

The main argument here (from 2 to 3) contains a subargument, in this case, the argument from 1 (a premise) to 2 (the intermediate conclusion). A subargument, as the term suggests, is a part of an argument that provides indirect support for the main argument. The main argument is simply the argument whose conclusion is the main conclusion.

Another type of structure that arguments can have is when two or more premises provide direct but independent support for the conclusion. Here is an example of an argument with that structure:

Wanda rode her bike to work today because when she arrived at work she had her right pant leg rolled up, which cyclists do to keep their pants legs from getting caught in the chain. Moreover, our co-worker, Bob, who works in accounting, saw her riding towards work at 7:45 a.m.

The conclusion of this argument is “Wanda rode her bike to work today”; two premises provide independent support for it: the fact that Wanda had her pant leg cuffed and the fact that Bob saw her riding her bike. Here is the argument in standard form:

1. Wanda arrived at work with her right pant leg rolled up.
2. Cyclists often roll up their right pant leg.
3. Bob saw Wanda riding her bike towards work at 7:45.
4. Therefore, Wanda rode her bike to work today. (from 1-2, 3 independently)

Again, notice that next to statement 4 of the argument is an indicator of how each part of the argument relates to the main conclusion. In this case, to avoid any ambiguity, you can see that the support for the conclusion comes independently from statements 1 and 2, on the one hand, and from statement 3, on the other hand. It is important to point out that an argument or subargument can be supported by one or more premises, the case in this argument because the main conclusion (4) is supported jointly by 1 and 2, and singly by 3. As before, we can represent the structure of this argument spatially, as the figure below shows:

 

There are endless argument structures that can be generated from a few simple patterns. At this point, it is important to understand that arguments can have different structures and that some arguments will be more complex than others. Determining the structure of complex arguments is a skill that takes some time to master, rather like simplifying equations in math. Even so, it may help to remember that any argument structure ultimately traces back to some combination of premises, intermediate arguments, and a main conclusion.
