How To Write A Formal Persuasive Essay

Structure and organization are integral components of an effective persuasive essay. No matter how intelligent the ideas, a paper lacking a strong introduction, well-organized body paragraphs and an insightful conclusion is not an effective paper.

The Introduction

Simply enough, the introductory paragraph introduces the argument of your paper. A well-constructed introductory paragraph immediately captures a reader’s interest and gives appropriate background information about the paper’s topic. Such a paragraph might include a brief summary of the ideas to be discussed in body of the paper as well as other information relevant to your paper’s argument. The most important function of the introductory paragraph, however, is to present a clear statement of the paper’s argument. This sentence is your paper’s thesis. Without a thesis, it is impossible for you to present an effective argument. The thesis sentence should reflect both the position that you will argue and the organizational pattern with which you will present and support your argument. A useful way to think about the construction of a thesis sentence is to view it in terms of stating both the “what” and the “how” of the paper’s argument. The “what” is simply the basic argument in your paper: what exactly are you arguing? The “how” is the strategy you will use to present this argument. The following are helpful questions for you to consider when formulating a thesis sentence:

  • What is the argument that I am trying to convince the reader to accept?
  • How exactly do I expect to convince the reader that this argument is sound?

Once you have answered these questions, the next step is to synthesize these answers into a single thesis sentence, or, if necessary, two thesis sentences.

For example: You want to convince your reader that the forces of industry did not shape American foreign policy from the late 19th century through 1914, and you plan to do this by showing that there were other factors which were much more influential in shaping American foreign policy. Both of these elements can be synthesized into a thesis sentence:

Fear of foreign influence in the Western hemisphere, national pride, and contemporary popular ideas concerning both expansion and foreign peoples had significantly more influence on American foreign policy than did the voices of industrialists.

This sentence shows the position you will argue and also sets up the organizational pattern of your paper's body.

The Body

The body of your paper contains the actual development of your paper’s argument. Each body paragraph presents a single idea or set of related ideas that provides support for your paper’s argument. Each body paragraph addresses one key aspect of your paper’s thesis and brings the reader closer to accepting the validity of your paper’s argument. Because each body paragraph should be a step in your argument, you should be mindful of the overall organization of your body paragraphs.

The first step in writing an effective body paragraph is the construction of the first sentence of this paragraph, the topic sentence. Just as the thesis sentence holds together your essay, the topic sentence is the glue binding each individual body paragraph. A body paragraph’s topic sentence serves two main purposes: introducing the content of the paragraph and introducing the next step of your argument. It is important to keep in mind that the goal of the topic sentence is to advance your paper's argument, not just to describe the content of the paragraph.

The first part in your thesis on page two states that fear of foreign influence in the Western Hemisphere had more influence on American foreign policy than did industry. Thus, you need to elaborate on this point in your body paragraphs.

An effective topic sentence for one of these paragraphs could be:

American fear of foreign influence was a key factor in the United States’ actions in the Spanish-American War. Subsequent body paragraphs might offer further evidence for the idea presented in this body paragraph.

A good way to test the strength of both your topic sentences and your argument as a whole is to construct an outline of your paper using only your paper's thesis statement and topic sentences. This outline should be a logical overview of your paper's argument; all of your paper’s topic sentences should work together to support your thesis statement.

The Conclusion

A basic purpose of your paper’s concluding paragraph is both to restate the paper’s argument and to restate how you have supported this argument in the body of the paper. However, your conclusion should not simply be a copy of your introduction. The conclusion draws together the threads of the paper’s argument and shows where the argument of your paper has gone. An effective conclusion gives the reader reasons for bothering to read your paper. One of the most important functions of this paragraph is to bring in fresh insight. Some possible questions to consider when writing your conclusion are:

  • What are some real world applications of this paper’s argument?
  • Why is what I am writing about important?
  • What are some of the questions that this paper’s argument raises?
  • What are the implications of this paper’s argument?

While the organization and structure described in this handout are necessary components of an effective persuasive essay, keep in mind that writing itself is a fluid process. There are no steadfast rules that you need to adhere to as you write. Simply because the introduction is the first paragraph in your essay does not mean that you must write this paragraph before any other. Think of the act of writing as an exploration of ideas, and let this sense of exploration guide you as you write your essay.

Argumentative Essays

Summary:

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.
