The Modes of Discourse—Exposition, Description, Narration, Argumentation (EDNA)—are common paper assignments you may encounter in your writing classes. Although these genres have been criticized by some composition scholars, the Purdue OWL recognizes the wide spread use of these approaches and students’ need to understand and produce them.

What is an argumentative essay?
The argumentative essay is a genre of writing that requires the student to investigate a topic; collect, generate, and evaluate evidence; and establish a position on the topic in a concise manner.
Please note: Some confusion may occur between the argumentative essay and the expository essay. These two genres are similar, but the argumentative essay differs from the expository essay in the amount of pre-writing (invention) and research involved. The argumentative essay is commonly assigned as a capstone or final project in first year writing or advanced composition courses and involves lengthy, detailed research. Expository essays involve less research and are shorter in length. Expository essays are often used for in-class writing exercises or tests, such as the GED or GRE.
Argumentative essay assignments generally call for extensive research of literature or previously published material. Argumentative assignments may also require empirical research where the student collects data through interviews, surveys, observations, or experiments. Detailed research allows the student to learn about the topic and to understand different points of view regarding the topic so that she/he may choose a position and support it with the evidence collected during research. Regardless of the amount or type of research involved, argumentative essays must establish a clear thesis and follow sound reasoning.
The structure of the argumentative essay is held together by the following.
- A clear, concise, and defined thesis statement that occurs in the first paragraph of the essay.
In the first paragraph of an argument essay, students should set the context by reviewing the topic in a general way. Next the author should explain why the topic is important (exigence) or why readers should care about the issue. Lastly, students should present the thesis statement. It is essential that this thesis statement be appropriately narrowed to follow the guidelines set forth in the assignment. If the student does not master this portion of the essay, it will be quite difficult to compose an effective or persuasive essay.
- Clear and logical transitions between the introduction, body, and conclusion.
Transitions are the mortar that holds the foundation of the essay together. Without logical progression of thought, the reader is unable to follow the essay’s argument, and the structure will collapse. Transitions should wrap up the idea from the previous section and introduce the idea that is to follow in the next section.
- Body paragraphs that include evidential support.
Each paragraph should be limited to the discussion of one general idea. This will allow for clarity and direction throughout the essay. In addition, such conciseness creates an ease of readability for one’s audience. It is important to note that each paragraph in the body of the essay must have some logical connection to the thesis statement in the opening paragraph. Some paragraphs will directly support the thesis statement with evidence collected during research. It is also important to explain how and why the evidence supports the thesis (warrant).
However, argumentative essays should also consider and explain differing points of view regarding the topic. Depending on the length of the assignment, students should dedicate one or two paragraphs of an argumentative essay to discussing conflicting opinions on the topic. Rather than explaining how these differing opinions are wrong outright, students should note how opinions that do not align with their thesis might not be well informed or how they might be out of date.
- Evidential support (whether factual, logical, statistical, or anecdotal).
The argumentative essay requires well-researched, accurate, detailed, and current information to support the thesis statement and consider other points of view. Some factual, logical, statistical, or anecdotal evidence should support the thesis. However, students must consider multiple points of view when collecting evidence. As noted in the paragraph above, a successful and well-rounded argumentative essay will also discuss opinions not aligning with the thesis. It is unethical to exclude evidence that may not support the thesis. It is not the student’s job to point out how other positions are wrong outright, but rather to explain how other positions may not be well informed or up to date on the topic.
- A conclusion that does not simply restate the thesis, but readdresses it in light of the evidence provided.
It is at this point of the essay that students may begin to struggle. This is the portion of the essay that will leave the most immediate impression on the mind of the reader. Therefore, it must be effective and logical. Do not introduce any new information into the conclusion; rather, synthesize the information presented in the body of the essay. Restate why the topic is important, review the main points, and review your thesis. You may also want to include a short discussion of more research that should be completed in light of your work.
A complete argument
Perhaps it is helpful to think of an essay in terms of a conversation or debate with a classmate. If I were to discuss the cause of World War II and its current effect on those who lived through the tumultuous time, there would be a beginning, middle, and end to the conversation. In fact, if I were to end the argument in the middle of my second point, questions would arise concerning the current effects on those who lived through the conflict. Therefore, the argumentative essay must be complete, and logically so, leaving no doubt as to its intent or argument.
The five-paragraph essay
A common method for writing an argumentative essay is the five-paragraph approach. This is, however, by no means the only formula for writing such essays. If it sounds straightforward, that is because it is; in fact, the method consists of (a) an introductory paragraph (b) three evidentiary body paragraphs that may include discussion of opposing views and (c) a conclusion.
Longer argumentative essays
Complex issues and detailed research call for complex and detailed essays. Argumentative essays discussing a number of research sources or empirical research will most certainly be longer than five paragraphs. Authors may have to discuss the context surrounding the topic, sources of information and their credibility, as well as a number of different opinions on the issue before concluding the essay. Many of these factors will be determined by the assignment.
Definition of Argumentative Essay
An argumentative essay is a type of essay that presents arguments about both sides of an issue. It could be that both sides are presented equally balanced, or it could be that one side is presented more forcefully than the other. It all depends on the writer, and what side he supports the most. The general structure of an argumentative essay follows this format:
- Introduction: Attention Grabber / hook, Background Information, Thesis Statement
- Body: Three body paragraphs (three major arguments)
- Counterargument: An argument to refute earlier arguments and give weight to the actual position
- Conclusion: Rephrasing the thesis statement, major points, call to attention, or concluding remarks.
Models for Argumentative Essays
There are two major models besides this structure given above, which is called a classical model. Two other models are the Toulmin and Rogerian models.
Toulmin model is comprised of an introduction with a claim or thesis, followed by presentation of data to support the claim. Warrants are then listed for the reasons to support the claim with backing and rebuttals. However, the Rogerian model asks to weigh two options, lists strengths and weaknesses of both options, and gives a recommendation after an analysis.
Examples of Argumentative Essay in Literature
Example #1: Put a Little Science in Your Life (by Brian Greene)
“When we consider the ubiquity of cellphones, iPods, personal computers and the Internet, it’s easy to see how science (and the technology to which it leads) is woven into the fabric of our day-to-day activities. When we benefit from CT scanners, M.R.I. devices, pacemakers and arterial stents, we can immediately appreciate how science affects the quality of our lives. When we assess the state of the world, and identify looming challenges like climate change, global pandemics, security threats and diminishing resources, we don’t hesitate in turning to science to gauge the problems and find solutions.
And when we look at the wealth of opportunities hovering on the horizon—stem cells, genomic sequencing, personalized medicine, longevity research, nanoscience, brain-machine interface, quantum computers, space technology—we realize how crucial it is to cultivate a general public that can engage with scientific issues; there’s simply no other way that as a society we will be prepared to make informed decisions on a range of issues that will shape the future.”
These two paragraphs present an argument about two scientific fields — digital products and biotechnology. It has also given full supporting details with names.
Example #2: Boys Here, Girls There: Sure, If Equality’s the Goal (by Karen Stabiner)
“The first objections last week came from the National Organization for Women and the New York Civil Liberties Union, both of which opposed the opening of TYWLS in the fall of 1996. The two groups continue to insist—as though it were 1896 and they were arguing Plessy v. Ferguson—that separate can never be equal. I appreciate NOW’s wariness of the Bush administration’s endorsement of single-sex public schools, since I am of the generation that still considers the label “feminist” to be a compliment—and many feminists still fear that any public acknowledgment of differences between the sexes will hinder their fight for equality.”
This paragraph by Karen Stabiner presents an objection to the argument of separation between public schools. It has been fully supported with evidences of the court case.
Example #3: The Flight from Conversation (by Sherry Turkle)
“We’ve become accustomed to a new way of being “alone together.” Technology-enabled, we are able to be with one another, and also elsewhere, connected to wherever we want to be. We want to customize our lives. We want to move in and out of where we are because the thing we value most is control over where we focus our attention. We have gotten used to the idea of being in a tribe of one, loyal to our own party.”
This is an argument by Sherry Turkle, beautifully presented it in the first person plural dialogues. However, it is clear that this is part of a greater argument instead of the essay.
Function of Argumentative Essay
An argumentative essay presents both sides of an issue. However, it presents one side more positively or meticulously than the other one, so that readers could be swayed to the one the author intends. The major function of this type of essays is to present a case before the readers in a convincing manner, showing them the complete picture.
