Compare & Contrast Thesis Statements
The thesis statement is the conclusion of the paper.
A good thesis statement is precise, succinct, and informative.
It is not simply a statement of the general topic, interest or plan. Nor is it a springboard to jump into other topics.
Consider the following compare and contrast thesis statements:
1. Rule utilitarianism and Kantian ethics share certain similarities and differences.
2. Both rule utilitarianism and Kantian ethics emphasize rules, but they are also different.
3. Confucian and Aristotelian ethics are more dissimilar than suggested by Chang Wejen in his paper Confucian Theories of Norms and Human Rights.
4. Aristotles notion of harmonious functioning for the relationship between a ruler and his subject is fundamentally similar to Confucius notion of reciprocity.
1 is clearly the worst, as it is not at all informative. 2 is a little better, but still lacking in specificity. 3 is pretty good, but not quite as good as 4, which is the best of this lot because it has the greatest level of specificity.
But the best compare and contrast theses go even a step further by showing how what appears to be a difference is really, at a deeper level of analysis, a similarity (or vice-versa). For example:
5 While both Kantian ethics and Aristotelian ethics seem to emphasize individual conduct, the Kantian system is more applicable to matters of social policy.
6. Despite the fundamental difference in how Kant and Aristotle ground morality, it is possible to derive a right to autonomy from both their ethical systems. [In the introduction, one would then go on to elaborate on what autonomy is and what it means to have a right to that autonomy].
Here's an example of what I mean when I say that you can try to defend a particular way of combining elements of both into a coherent hybrid theory. The philosopher David Cuminsky recently proposed to incorporate Kant's theory of value intoa consequentalist framework. I would summarize his thesis as follows:
7. While the consequentalist is essentially correct that we should be trying to maximize the good, the Kantian idea of grounding value in autonomy or the good will provides the best account of the good.
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.
