How can I effectively present my argument?

Use an organizational structure that arranges the argument in a way that will make sense to the reader. The Toulmin Method of logic is a common and easy to use formula for organizing an argument.

The basic format for the Toulmin Method is as follows.

Claim: The overall thesis the writer will argue for.

Data: Evidence gathered to support the claim.

Warrant (also referred to as a bridge): Explanation of why or how the data supports the claim, the underlying assumption that connects your data to your claim.

Backing (also referred to as the foundation): Additional logic or reasoning that may be necessary to support the warrant.

Counterclaim: A claim that negates or disagrees with the thesis/claim.

Rebuttal: Evidence that negates or disagrees with the counterclaim.

Including a well-thought-out warrant or bridge is essential to writing a good argumentative essay or paper. 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.

Don't avoid the opposing side of an argument. Instead, include the opposing side as a counterclaim. Find out what the other side is saying and respond to it within your own argument. This is important so that the audience is not swayed by weak, but unrefuted, arguments. Including counterclaims allows you to find common ground with more of your readers. It also makes you look more credible because you appear to be knowledgeable about the entirety of the debate rather than just being biased or uninformed. You may want to include several counterclaims to show that you have thoroughly researched the topic.


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: Because cars are the largest source of private, as opposed to industry produced, 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 a 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: This combination of technologies means that less pollution is produced. According to "the hybrid engine of the Prius, made by Toyota, produces 90 percent fewer harmful emissions than a comparable gasoline engine."

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

Rebuttal: While mass transit is an environmentally sound 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.


What is Toulmin Argument

Toulmin Argumentation is a model of argument which suggests six parts in any argumentative text. These elements include: data, claim, warrants, qualifiers, rebuttals and backing statements. Basically, Toulmin Argument analyzes the aspects of your position paper, for instance, so that you can identify the weak points of your arguments and work on them while further improving your strong points as needed. Here are the basic items involved in Toulmin Arguments.

  1. Data/Grounds

  2. These are the evidence that you will use to support your claim or position.

  3. Claim

  4. The statement which you are offering for others, such as your readers or listeners, to accept.

  5. Warrants

  6. These link your data/grounds with your claim. They also explain why the data supports the claim.

  7. Qualifiers

  8. These are words or phrases which show the strength of the connection between the claim and the data.

  9. Rebuttals

  10. These are the arguments which are directed against the possible objections to your claim.

  11. Backing Statements

  12. These give extra support to your warrants.

Here is an example of a Toulmin Argument:

You should stop smoking [Claim]because studies show that almost [Qualifier] 80% of smokers can develop lung cancer [Data/Ground]. Stopping a bad habit can help reduce the occurence of its bad consequences[Warrant, *can be stated or left unstated]. Life expectancy is lengthened if habits bad to one's health are stopped [Backing Statement]. Although it is not always the case that people who smoke will suffer from lung cancer, the risks are higher for those who smoke routinely [Rebuttal].
