Introductions and conclusions play a special role in the academic essay, and they frequently demand much of your attention as a writer. A good introduction should identify your topic, provide essential context, and indicate your particular focus in the essay. It also needs to engage your readers’ interest. A strong conclusion will provide a sense of closure to the essay while again placing your concepts in a somewhat wider context. It will also, in some instances, add a stimulus to further thought. Since no two essays are the same, no single formula will automatically generate an introduction and conclusion for you. But the following guidelines will help you to construct a suitable beginning and end for your essay.
Some general advice about introductions
- Some students cannot begin writing the body of the essay until they feel they have the perfect introduction. Be aware of the dangers of sinking too much time into the introduction. Some of that time can be more usefully channeled into planning and writing.
- You may be the kind of writer who writes an introduction first in order to explore your own thinking on the topic. If so, remember that you may at a later stage need to compress your introduction.
- It can be fine to leave the writing of the introduction for a later stage in the essay-writing process. Some people write their introduction only after they have completed the rest of the essay. Others write the introduction first but rewrite it significantly in light of what they end up saying in the body of their paper.
- The introductions for most papers can be effectively written in one paragraph occupying half to three-quarters of the first page. Your introduction may be longer than that, and it may take more than one paragraph, but be sure you know why. The size of your introduction should bear some relationship to the length and complexity of your paper. A twenty page paper may call for a two-page introduction, but a five-page paper will not.
- Get to the point as soon as possible. Generally, you want to raise your topic in your very first sentences. A common error is to begin too broadly or too far off topic. Avoid sweeping generalizations.
- If your essay has a thesis, your thesis statement will typically appear at the end of your introduction, even though that is not a hard-and-fast rule. You may, for example, follow your thesis with a brief road map to your essay that sketches the basic structure of your argument. The longer the paper, the more useful a road map becomes.
How do I write an interesting, effective introduction?
Consider these strategies for capturing your readers’ attention and for fleshing out your introduction:
- Find a startling statistic that illustrates the seriousness of the problem you will address.
- Quote an expert (but be sure to introduce him or her first).
- Mention a common misperception that your thesis will argue against.
- Give some background information necessary for understanding the essay.
- Use a brief narrative or anecdote that exemplifies your reason for choosing the topic. In an assignment that encourages personal reflection, you may draw on your own experiences; in a research essay, the narrative may illustrate a common real-world scenario.
- In a science paper, explain key scientific concepts and refer to relevant literature. Lead up to your own contribution or intervention.
- In a more technical paper, define a term that is possibly unfamiliar to your audience but is central to understanding the essay.
In fleshing out your introduction, you will want to avoid some common pitfalls:
- Don’t provide dictionary definitions, especially of words your audience already knows.
- Don’t repeat the assignment specifications using the professor’s wording.
- Don’t give details and in-depth explanations that really belong in your body paragraphs. You can usually postpone background material to the body of the essay.
Some general advice about conclusions
- A conclusion is not merely a summary of your points or a re-statement of your thesis. If you wish to summarize—and often you must—do so in fresh language. Remind the reader of how the evidence you’ve presented has contributed to your thesis.
- The conclusion, like much of the rest of the paper, involves critical thinking. Reflect upon the significance of what you’ve written. Try to convey some closing thoughts about the larger implications of your argument.
- Broaden your focus a bit at the end of the essay. A good last sentence leaves your reader with something to think about, a concept in some way illuminated by what you’ve written in the paper.
- For most essays, one well-developed paragraph is sufficient for a conclusion. In some cases, a two-or-three paragraph conclusion may be appropriate. As with introductions, the length of the conclusion should reflect the length of the essay.
How do I write an interesting, effective conclusion?
The following strategies may help you move beyond merely summarizing the key points of your essay:
- If your essay deals with a contemporary problem, warn readers of the possible consequences of not attending to the problem.
- Recommend a specific course of action.
- Use an apt quotation or expert opinion to lend authority to the conclusion you have reached.
- Give a startling statistic, fact, or visual image to drive home the ultimate point of your paper.
- If your discipline encourages personal reflection, illustrate your concluding point with a relevant narrative drawn from your own life experiences.
- Return to an anecdote, example, or quotation that you introduced in your introduction, but add further insight that derives from the body of your essay.
- In a science or social science paper, mention worthwhile avenues for future research on your topic.
How does genre affect my introduction or conclusion?
Most of the advice in this handout pertains to argumentative or exploratory academic essays. Be aware, however, that different genres have their own special expectations about beginnings and endings. Some academic genres may not even require an introduction or conclusion. An annotated bibliography, for example, typically provides neither. A book review may begin with a summary of the book and conclude with an overall assessment of it. A policy briefing usually includes an introduction but may conclude with a series of recommendations. Check your assignment carefully for any directions about what to include in your introduction or conclusion.
What is a comparative essay?
A comparative essay asks that you compare at least two (possibly more) items. These items will differ depending on the assignment. You might be asked to compare
- positions on an issue (e.g., responses to midwifery in Canada and the United States)
- theories (e.g., capitalism and communism)
- figures (e.g., GDP in the United States and Britain)
- texts (e.g., Shakespeare’s Hamletand Macbeth)
- events (e.g., the Great Depression and the global financial crisis of 2008–9)
Although the assignment may say “compare,” the assumption is that you will consider both the similarities and differences; in other words, you will compare and contrast.
Make sure you know the basis for comparison
The assignment sheet may say exactly what you need to compare, or it may ask you to come up with a basis for comparison yourself.
- Provided by the essay question: The essay question may ask that you consider the figure of the gentleman in Charles Dickens’s Great Expectations and Anne Brontë’s The Tenant of Wildfell Hall. The basis for comparison will be the figure of the gentleman.
- Developed by you: The question may simply ask that you compare the two novels. If so, you will need to develop a basis for comparison, that is, a theme, concern, or device common to both works from which you can draw similarities and differences.
Develop a list of similarities and differences
Once you know your basis for comparison, think critically about the similarities and differences between the items you are comparing, and compile a list of them.
For example, you might decide that in Great Expectations, being a true gentleman is not a matter of manners or position but morality, whereas in The Tenant of Wildfell Hall, being a true gentleman is not about luxury and self-indulgence but hard work and productivity.
The list you have generated is not yet your outline for the essay, but it should provide you with enough similarities and differences to construct an initial plan.
Develop a thesis based on the relative weight of similarities and differences
Once you have listed similarities and differences, decide whether the similarities on the whole outweigh the differences or vice versa. Create a thesis statement that reflects their relative weights. A more complex thesis will usually include both similarities and differences. Here are examples of the two main cases:
- Differences outweigh similarities:
While Callaghan’s “All the Years of Her Life” and Mistry’s “Of White Hairs and Cricket” both follow the conventions of the coming-of-age narrative, Callaghan’s story adheres more closely to these conventions by allowing its central protagonist to mature. In Mistry’s story, by contrast, no real growth occurs.
- Similarities outweigh differences:
Although Darwin and Lamarck came to different conclusions about whether acquired traits can be inherited, they shared the key distinction of recognizing that species evolve over time.
Come up with a structure for your essay
- Alternating method: Point-by-point patternIn the alternating method, you find related points common to your central subjects A and B, and alternate between A and B on the basis of these points (ABABAB …). For instance, a comparative essay on the French and Russian revolutions might examine how both revolutions either encouraged or thwarted innovation in terms of new technology, military strategy, and the administrative system.
A Paragraph 1 in body new technology and the French Revolution B Paragraph 2 in body new technology and the Russian Revolution A Paragraph 3 in body military strategy and the French Revolution B Paragraph 4 in body military strategy and the Russian Revolution A Paragraph 5 in body administrative system and the French Revolution B Paragraph 6 in body administrative system and the Russian Revolution
Note that the French and Russian revolutions (A and B) may be dissimilar rather than similar in the way they affected innovation in any of the three areas of technology, military strategy, and administration. To use the alternating method, you just need to have something noteworthy to say about both A and B in each area. Finally, you may certainly include more than three pairs of alternating points: allow the subject matter to determine the number of points you choose to develop in the body of your essay.
When do I use the alternating method? Professors often like the alternating system because it generally does a better job of highlighting similarities and differences by juxtaposing your points about A and B. It also tends to produce a more tightly integrated and analytical paper. Consider the alternating method if you are able to identify clearly related points between A and B. Otherwise, if you attempt to impose the alternating method, you will probably find it counterproductive.
- Block method: Subject-by-subject patternIn the block method (AB), you discuss all of A, then all of B. For example, a comparative essay using the block method on the French and Russian revolutions would address the French Revolution in the first half of the essay and the Russian Revolution in the second half. If you choose the block method, however, do not simply append two disconnected essays to an introductory thesis. The B block, or second half of your essay, should refer to the A block, or first half, and make clear points of comparison whenever comparisons are relevant. (“Unlike A, B . . .” or “Like A, B . . .”) This technique will allow for a higher level of critical engagement, continuity, and cohesion.
A Paragraphs 1–3 in body How the French Revolution encouraged or thwarted innovation B Paragraphs 4–6 in body How the Russian Revolution encouraged or thwarted innovation
When do I use the block method? The block method is particularly useful in the following cases:
- You are unable to find points about A and B that are closely related to each other.
- Your ideas about B build upon or extend your ideas about A.
- You are comparing three or more subjects as opposed to the traditional two.
