9 Toulmin Argument Model

By liza long, amy minervini, and joel gladd.

Stephen Edelston Toulmin (born March 25, 1922) was a British philosopher, author, and educator. Toulmin devoted his works to analyzing moral reasoning. He sought to develop practical ways to evaluate ethical arguments effectively. The Toulmin Model of Argumentation, a diagram containing six interrelated components, was considered Toulmin’s most influential work, particularly in the fields of rhetoric, communication, and computer science. His components continue to provide useful means for analyzing arguments.

The following are the parts of a Toulmin argument (see Figure 9.1 for an example):

Claim: The claim is a statement that you are asking the other person to accept as true (i.e., a conclusion) and forms the nexus of the Toulmin argument because all the other parts relate back to the claim. The claim can include information and ideas you are asking readers to accept as true or actions you want them to accept and enact. One example of a claim is the following:

My grandfather should wear a hearing aid.

This claim both asks the reader to believe an idea and suggests an action to enact. However, like all claims, it can be challenged. Thus, a Toulmin argument does not end with a claim but also includes grounds and warrant to give support and reasoning to the claim.

Grounds: The grounds form the basis of real persuasion and include the reasoning behind the claim, data, and proof of expertise. Think of grounds as a combination of premises and support. The truth of the claim rests upon the grounds, so those grounds should be tested for strength, credibility, relevance, and reliability. The following are examples of grounds:

Over 70% of all people over 65 years have a hearing difficulty. Hearing aids raise hearing quality.

Information is usually a powerful element of persuasion, although it does affect people differently. Those who are dogmatic, logical, or rational will more likely be persuaded by factual data. Those who argue emotionally and who are highly invested in their own position will challenge it or otherwise try to ignore it. Thus, grounds can also include appeals to emotion, provided they aren’t misused. The best arguments, however, use a variety of support and rhetorical appeals.

Warrant: A warrant links data and other grounds to a claim, legitimizing the claim by showing the grounds to be relevant. The warrant may be carefully explained and explicit or unspoken and implicit. The warrant answers the question, “Why does that data mean your claim is true?” For example,

A hearing aid helps most people hear better.

The warrant may be simple, and it may also be a longer argument with additional sub-elements including those described below. Warrants may be based on logos, ethos or pathos, or values that are assumed to be shared with the listener. In many arguments, warrants are often implicit and, hence, unstated. This gives space for the other person to question and expose the warrant, perhaps to show it is weak or unfounded.

Backing: The backing for an argument gives additional support to the warrant. Backing can be confused with grounds, but the main difference is this: grounds should directly support the premises of the main argument itself, while backing exists to help the warrants make more sense. For example,

Hearing aids are available locally.

This statement works as backing because it gives credence to the warrant stated above, that a hearing aid will help most people hear better. The fact that hearing aids are readily available makes the warrant even more reasonable.

Qualifier: The qualifier indicates how the data justifies the warrant and may limit how universally the claim applies. The necessity of qualifying words comes from the plain fact that most absolute claims are ultimately false (all women want to be mothers, e.g.) because one counterexample sinks them immediately. Thus, most arguments need some sort of qualifier, words that temper an absolute claim and make it more reasonable. Common qualifiers include “most,” “usually,” “always,” or “sometimes.” For example,

Hearing aids help most people.

The qualifier “most” here allows for the reasonable understanding that rarely does one thing (a hearing aid) universally benefit all people. Another variant is the reservation, which may give the possibility of the claim being incorrect:

Unless there is evidence to the contrary, hearing aids do no harm to ears.

Qualifiers and reservations can be used to bolster weak arguments, so it is important to recognize them. They are often used by advertisers who are constrained not to lie. Thus, they slip “usually,” “virtually,” “unless,” and so on into their claims to protect against liability. While this may seem like sneaky practice, and it can be for some advertisers, it is important to note that the use of qualifiers and reservations can be a useful and legitimate part of an argument.

Rebuttal: Despite the careful construction of the argument, there may still be counterarguments that can be used. These may be rebutted either through a continued dialogue, or by pre-empting the counter-argument by giving the rebuttal during the initial presentation of the argument. For example, if you anticipated a counterargument that hearing aids, as a technology, may be fraught with technical difficulties, you would include a rebuttal to deal with that counterargument:

There is a support desk that deals with technical problems.

Any rebuttal is an argument in itself, and thus may include a claim, warrant, backing, and the other parts of the Toulmin structure.

Even if you do not wish to write an essay using strict Toulmin structure, using the Toulmin checklist can make an argument stronger. When first proposed, Toulmin based his layout on legal arguments, intending it to be used analyzing arguments typically found in the courtroom; in fact, Toulmin did not realize that this layout would be applicable to other fields until later. The first three elements–“claim,” “grounds,” and “warrant”–are considered the essential components of practical arguments, while the last three—“qualifier,” “backing,” and “rebuttal”—may not be necessary for all arguments.

Why Does Toulmin Argument Matter?

Toulmin’s model of argumentation is particularly valuable for college students because it provides a structured framework for analyzing and constructing arguments, skills that are essential across various academic disciplines and real-world situations.

By understanding Toulmin’s components—claim, evidence, warrant, backing, qualifier, and rebuttal—students can develop more coherent, persuasive arguments and critically evaluate the arguments of others. This model encourages students to think deeply about the logic and effectiveness of their argumentation, emphasizing the importance of supporting claims with solid evidence and reasoning. Additionally, familiarity with Toulmin’s model prepares students for scenarios involving critical analysis and debate, whether in writing essays, participating in discussions, or presenting research.

By mastering this model, students enhance their ability to communicate effectively, a crucial skill for academic success and professional advancement.

When should writers or speakers consider Toulmin’s model of argument?

Toulmin’s model of argument works especially well in situations where disputes are being reviewed by a third party — such as judge, an arbitrator, or evaluation committee.

Declarative knowledge of Toulmin Argument helps with

• inventing or developing your own arguments (even if you’re developing a Rogerian or Aristotelian argument )
• critiquing your arguments or the arguments of others.

Summary of Stephen Toulmin’s Model of Argument

The three essential components of argument.

Stephen Toulmin’s model of argument posits the three essential elements of an argument are

• Data (aka a Fact or Evidence)
• Warrant (which the writer, speaker, knowledge worker . . . may imply rather than explicitly state).

Toulmin’s model presumes data, matters of fact and opinion, must be supplied as evidence to support a claim. The claim focuses the discourse by explicitly stating the desired conclusion of the argument.

In turn, a warrant, the third essential component of an argument, provides the reasoning that links the data to the claim.

The example in Figure 1 demonstrates the abstract, hypothetical linking between a claim and data that a warrant provides. Prior to this link–that. people born in Bermuda are British–the claim that Harry is a British subject because he was born in Bermuda is unsubstantiated.

The 6 Elements of Successful Argument

While the argument presented in Figure 1 is a simple one, life is not always simple.

In situations where people are likely to dispute the application of a warrant to data, you may need to develop backing for your warrants. o account for the conflicting desires and assumptions of an audience, Toulmin identifies a second triad of components that may not be used:

• Reservation
• Qualification.

How can I effectively present my argument?

In order for your argument to be persuasive, it must use an organizational structure that the audience perceives as both logical and easy to parse. Three argumentative methods —the  Toulmin Method , Classical Method , and Rogerian Method — give guidance for how to organize the points in an argument.

Note that these are only three of the most popular models for organizing an argument. Alternatives exist. Be sure to consult your instructor and/or defer to your assignment’s directions if you’re unsure which to use (if any).

Toulmin Method

The  Toulmin Method  is a formula that allows writers to build a sturdy logical foundation for their arguments. First proposed by author Stephen Toulmin in  The Uses of Argument (1958), the Toulmin Method emphasizes building a thorough support structure for each of an argument's key claims.

The basic format for the Toulmin Method  is as follows:

Claim:  In this section, you explain your overall thesis on the subject. In other words, you make your main argument.

Data (Grounds):  You should use evidence to support the claim. In other words, provide the reader with facts that prove your argument is strong.

Warrant (Bridge):  In this section, you explain why or how your data supports the claim. As a result, the underlying assumption that you build your argument on is grounded in reason.

Backing (Foundation):  Here, you provide any additional logic or reasoning that may be necessary to support the warrant.

Counterclaim:  You should anticipate a counterclaim that negates the main points in your argument. Don't avoid arguments that oppose your own. Instead, become familiar with the opposing perspective.   If you respond to counterclaims, you appear unbiased (and, therefore, you earn the respect of your readers). You may even want to include several counterclaims to show that you have thoroughly researched the topic.

Rebuttal:  In this section, you incorporate your own evidence that disagrees with the counterclaim. It is essential to include a thorough warrant or bridge to strengthen your essay’s argument. If you present data to your audience without explaining how it supports your thesis, your readers may not make a connection between the two, or they may draw different conclusions.

Example of the Toulmin Method:

Claim:  Hybrid cars are an effective strategy to fight pollution.

Data1:  Driving a private car is a typical citizen's most air-polluting activity.

Warrant 1:  Due to the fact that cars are the largest source of private (as opposed to industrial) air pollution, switching to hybrid cars should have an impact on fighting pollution.

Data 2:  Each vehicle produced is going to stay on the road for roughly 12 to 15 years.

Warrant 2:  Cars generally have a long lifespan, meaning that the decision to switch to a hybrid car will make a long-term impact on pollution levels.

Data 3:  Hybrid cars combine a gasoline engine with a battery-powered electric motor.

Warrant 3:  The combination of these technologies produces less pollution.

Counterclaim:  Instead of focusing on cars, which still encourages an inefficient culture of driving even as it cuts down on pollution, the nation should focus on building and encouraging the use of mass transit systems.

Rebuttal:  While mass transit is an idea that should be encouraged, it is not feasible in many rural and suburban areas, or for people who must commute to work. Thus, hybrid cars are a better solution for much of the nation's population.

Rogerian Method

The Rogerian Method  (named for, but not developed by, influential American psychotherapist Carl R. Rogers) is a popular method for controversial issues. This strategy seeks to find a common ground between parties by making the audience understand perspectives that stretch beyond (or even run counter to) the writer’s position. Moreso than other methods, it places an emphasis on reiterating an opponent's argument to his or her satisfaction. The persuasive power of the Rogerian Method lies in its ability to define the terms of the argument in such a way that:

• your position seems like a reasonable compromise.
• you seem compassionate and empathetic.

The basic format of the Rogerian Method  is as follows:

Introduction:  Introduce the issue to the audience, striving to remain as objective as possible.

Opposing View : Explain the other side’s position in an unbiased way. When you discuss the counterargument without judgement, the opposing side can see how you do not directly dismiss perspectives which conflict with your stance.

Statement of Validity (Understanding):  This section discusses how you acknowledge how the other side’s points can be valid under certain circumstances. You identify how and why their perspective makes sense in a specific context, but still present your own argument.

Statement of Your Position:  By this point, you have demonstrated that you understand the other side’s viewpoint. In this section, you explain your own stance.

Statement of Contexts : Explore scenarios in which your position has merit. When you explain how your argument is most appropriate for certain contexts, the reader can recognize that you acknowledge the multiple ways to view the complex issue.

Statement of Benefits:  You should conclude by explaining to the opposing side why they would benefit from accepting your position. By explaining the advantages of your argument, you close on a positive note without completely dismissing the other side’s perspective.

Example of the Rogerian Method:

Introduction:  The issue of whether children should wear school uniforms is subject to some debate.

Opposing View:  Some parents think that requiring children to wear uniforms is best.

Statement of Validity (Understanding):  Those parents who support uniforms argue that, when all students wear the same uniform, the students can develop a unified sense of school pride and inclusiveness.

Statement of Your Position : Students should not be required to wear school uniforms. Mandatory uniforms would forbid choices that allow students to be creative and express themselves through clothing.

Statement of Contexts:  However, even if uniforms might hypothetically promote inclusivity, in most real-life contexts, administrators can use uniform policies to enforce conformity. Students should have the option to explore their identity through clothing without the fear of being ostracized.

Statement of Benefits:  Though both sides seek to promote students' best interests, students should not be required to wear school uniforms. By giving students freedom over their choice, students can explore their self-identity by choosing how to present themselves to their peers.

Classical Method

The Classical Method of structuring an argument is another common way to organize your points. Originally devised by the Greek philosopher Aristotle (and then later developed by Roman thinkers like Cicero and Quintilian), classical arguments tend to focus on issues of definition and the careful application of evidence. Thus, the underlying assumption of classical argumentation is that, when all parties understand the issue perfectly, the correct course of action will be clear.

The basic format of the Classical Method  is as follows:

Introduction (Exordium): Introduce the issue and explain its significance. You should also establish your credibility and the topic’s legitimacy.

Statement of Background (Narratio): Present vital contextual or historical information to the audience to further their understanding of the issue. By doing so, you provide the reader with a working knowledge about the topic independent of your own stance.

Proposition (Propositio): After you provide the reader with contextual knowledge, you are ready to state your claims which relate to the information you have provided previously. This section outlines your major points for the reader.

Proof (Confirmatio): You should explain your reasons and evidence to the reader. Be sure to thoroughly justify your reasons. In this section, if necessary, you can provide supplementary evidence and subpoints.

Refutation (Refuatio): In this section, you address anticipated counterarguments that disagree with your thesis. Though you acknowledge the other side’s perspective, it is important to prove why your stance is more logical.  

Conclusion (Peroratio): You should summarize your main points. The conclusion also caters to the reader’s emotions and values. The use of pathos here makes the reader more inclined to consider your argument.  

Example of the Classical Method:  

Introduction (Exordium): Millions of workers are paid a set hourly wage nationwide. The federal minimum wage is standardized to protect workers from being paid too little. Research points to many viewpoints on how much to pay these workers. Some families cannot afford to support their households on the current wages provided for performing a minimum wage job .

Statement of Background (Narratio): Currently, millions of American workers struggle to make ends meet on a minimum wage. This puts a strain on workers’ personal and professional lives. Some work multiple jobs to provide for their families.

Proposition (Propositio): The current federal minimum wage should be increased to better accommodate millions of overworked Americans. By raising the minimum wage, workers can spend more time cultivating their livelihoods.

Proof (Confirmatio): According to the United States Department of Labor, 80.4 million Americans work for an hourly wage, but nearly 1.3 million receive wages less than the federal minimum. The pay raise will alleviate the stress of these workers. Their lives would benefit from this raise because it affects multiple areas of their lives.

Refutation (Refuatio): There is some evidence that raising the federal wage might increase the cost of living. However, other evidence contradicts this or suggests that the increase would not be great. Additionally,   worries about a cost of living increase must be balanced with the benefits of providing necessary funds to millions of hardworking Americans.

Conclusion (Peroratio): If the federal minimum wage was raised, many workers could alleviate some of their financial burdens. As a result, their emotional wellbeing would improve overall. Though some argue that the cost of living could increase, the benefits outweigh the potential drawbacks.

Writing prompt.

Throughout English Composition II, you have utilized research skills, problem solving skills, and analytic skills.  The Toulmin Essay provides the student the opportunity to revisit some elements of Classical Argument and analyze another form of argumentative structure.

The essay should include the folllowing:

• 3 to 4 pages (double-spaced), not including the Works Cited page
• In-text citations in the body of the essay
• Works Cited page with your credible sources
• A minimum of 4 sources

To complete this assignment, you should:

• Begin with the issue you used in the Classical Argument
• Gather and evaluate sources
• Establish a thesis and academic level paragraphs
• Write a rough draft and complete revision exercises
• Submit a polished, academic level essay using MLA citation and format

An argument written in this manner unfolds both the strengths and limits of the argument.  This is as it should be.  No argument should pretend to be stronger than it is or apply further than it is meant to.  The point here isn't to "win" or "beat" all the counterarguments; the point is to come as close to the truth or as close to a realistic and feasible solution as we possibly can.  Toulmin's model reminds us that arguments are generally expressed with qualifiers and rebuttals rather than asserted as absolutes.  This lets the reader know how to take the reasoning, how far it is meant to be applied, and how general it is meant to be.  For this essay, you will craft a Toulmin argument utilizing your working annotated bibliography/research proposal and topic and how it applies to a global audience.

This assignment helps you practice the following skills that are essential to your success in school and your professional life beyond school.  In this assignment you will:

• Access and collect needed information from appropriate primary and secondary sources
• Synthesize information to develop informed views to produce and refute argumentation
• Compose a well-organized, Toulmin argument to expand your knowledge of a topic
