4.1: Introduction to Comparison and Contrast Essay

• Last updated
• Save as PDF
• Page ID 174873

The key to a good compare-and-contrast essay is to choose two or more subjects that connect in a meaningful way. Comparison and contrast is simply telling how two things are alike or different. The compare-and-contrast essay starts with a thesis that clearly states the two subjects that are to be compared, contrasted, or both. The thesis should focus on comparing, contrasting, or both.

Key Elements of the Compare and Contrast:

• A compare-and-contrast essay analyzes two subjects by either comparing them, contrasting them, or both.
• The purpose of writing a comparison or contrast essay is not to state the obvious but rather to illuminate subtle differences or unexpected similarities between two subjects.
• The thesis should clearly state the subjects that are to be compared, contrasted, or both, and it should state what is to be learned from doing so.
• Organize by the subjects themselves, one then the other.
• Organize by individual points, in which you discuss each subject in relation to each point.
• Use phrases of comparison or phrases of contrast to signal to readers how exactly the two subjects are being analyzed.

Objectives: By the end of this unit, you will be able to

• Identify compare & contrast relationships in model essays
• Construct clearly formulated thesis statements that show compare & contrast relationships
• Use pre-writing techniques to brainstorm and organize ideas showing a comparison and/or contrast
• Construct an outline for a five-paragraph compare & contrast essay
• Write a five-paragraph compare & contrast essay
• Use a variety of vocabulary and language structures that express compare & contrast essay relationships

Example Thesis: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Sample Paragraph:

Organic grown tomatoes purchased at the farmers’ market are very different from tomatoes that are grown conventionally. To begin with, although tomatoes from both sources will mostly be red, the tomatoes at the farmers’ market are a brighter red than those at a grocery store. That doesn’t mean they are shinier—in fact, grocery store tomatoes are often shinier since they have been waxed. You are likely to see great size variation in tomatoes at the farmers’ market, with tomatoes ranging from only a couple of inches across to eight inches across. By contrast, the tomatoes in a grocery store will be fairly uniform in size. All the visual differences are interesting, but the most important difference is the taste. The farmers’ market tomatoes will be bursting with flavor from ripening on the vine in their own time. However, the grocery store tomatoes are often close to being flavorless. In conclusion, the differences in organic and conventionally grown tomatoes are obvious in color, size and taste.

What is a Comparative Essay?

A comparative essay is a type of essay in which an essay writer compares at least two or more items. The author compares two subjects with the same relation in terms of similarities and differences depending on the assignment.

The main purpose of the comparative essay is to:

• Highlight the similarities and differences in a systematic manner.
• Provide great clarity of the subject to the readers.
• Analyze two things and describe their advantages and drawbacks.

A comparative essay is also known as compare and contrast essay or a comparison essay. It analyzes two subjects by either comparing them, contrasting them, or both. The Venn diagram is the best tool for writing a paper about the comparison between two subjects.  

Moreover, a comparative analysis essay discusses the similarities and differences of themes, items, events, views, places, concepts, etc. For example, you can compare two different novels (e.g., The Adventures of Huckleberry Finn and The Red Badge of Courage).

However, a comparative essay is not limited to specific topics. It covers almost every topic or subject with some relation.

Comparative Essay Structure

A good comparative essay is based on how well you structure your essay. It helps the reader to understand your essay better. 

The structure is more important than what you write. This is because it is necessary to organize your essay so that the reader can easily go through the comparisons made in an essay.

The following are the two main methods in which you can organize your comparative essay.

Point-by-Point Method 

The point-by-point or alternating method provides a detailed overview of the items that you are comparing. In this method, organize items in terms of similarities and differences.

This method makes the writing phase easy for the writer to handle two completely different essay subjects. It is highly recommended where some depth and detail are required.

Below given is the structure of the point-by-point method. 

Block Method 

The block method is the easiest as compared to the point-by-point method. In this method, you divide the information in terms of parameters. It means that the first paragraph compares the first subject and all their items, then the second one compares the second, and so on.

However, make sure that you write the subject in the same order. This method is best for lengthy essays and complicated subjects.

Here is the structure of the block method. 

Therefore, keep these methods in mind and choose the one according to the chosen subject.

Mixed Paragraphs Method

In this method, one paragraph explains one aspect of the subject. As a writer, you will handle one point at a time and one by one. This method is quite beneficial as it allows you to give equal weightage to each subject and help the readers identify the point of comparison easily.

How to Start a Comparative Essay?

Here, we have gathered some steps that you should follow to start a well-written comparative essay.  

Choose a Topic

The foremost step in writing a comparative essay is to choose a suitable topic.

Choose a topic or theme that is interesting to write about and appeals to the reader. 

An interesting essay topic motivates the reader to know about the subject. Also, try to avoid complicated topics for your comparative essay. 

Develop a List of Similarities and Differences 

Create a list of similarities and differences between two subjects that you want to include in the essay. Moreover, this list helps you decide the basis of your comparison by constructing your initial plan. 

Evaluate the list and establish your argument and thesis statement .

Establish the Basis for Comparison 

The basis for comparison is the ground for you to compare the subjects. In most cases, it is assigned to you, so check your assignment or prompt.

Furthermore, the main goal of the comparison essay is to inform the reader of something interesting. It means that your subject must be unique to make your argument interesting.  

Do the Research 

In this step, you have to gather information for your subject. If your comparative essay is about social issues, historical events, or science-related topics, you must do in-depth research.    

However, make sure that you gather data from credible sources and cite them properly in the essay.

Create an Outline

An essay outline serves as a roadmap for your essay, organizing key elements into a structured format.

With your topic, list of comparisons, basis for comparison, and research in hand, the next step is to create a comprehensive outline. 

Here is a standard comparative essay outline:

How to Write a Comparative Essay?

Now that you have the basic information organized in an outline, you can get started on the writing process. 

Here are the essential parts of a comparative essay: 

Comparative Essay Introduction 

Start off by grabbing your reader's attention in the introduction . Use something catchy, like a quote, question, or interesting fact about your subjects. 

Then, give a quick background so your reader knows what's going on. 

The most important part is your thesis statement, where you state the main argument , the basis for comparison, and why the comparison is significant.

This is what a typical thesis statement for a comparative essay looks like:

Comparative Essay Body Paragraphs 

The body paragraphs are where you really get into the details of your subjects. Each paragraph should focus on one thing you're comparing.

Start by talking about the first point of comparison. Then, go on to the next points. Make sure to talk about two to three differences to give a good picture.

After that, switch gears and talk about the things they have in common. Just like you discussed three differences, try to cover three similarities. 

This way, your essay stays balanced and fair. This approach helps your reader understand both the ways your subjects are different and the ways they are similar. Keep it simple and clear for a strong essay.

Comparative Essay Conclusion

In your conclusion , bring together the key insights from your analysis to create a strong and impactful closing.

Consider the broader context or implications of the subjects' differences and similarities. What do these insights reveal about the broader themes or ideas you're exploring?

Discuss the broader implications of these findings and restate your thesis. Avoid introducing new information and end with a thought-provoking statement that leaves a lasting impression.

How to Write a Comparative Essay

Last Updated: May 19, 2023 Fact Checked

This article was co-authored by Christopher Taylor, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014.

Perhaps you have been assigned a comparative essay in class, or need to write a comprehensive comparative report for work. In order to write a stellar comparative essay, you have to start off by picking two subjects that have enough similarities and differences to be compared in a meaningful way, such as two sports teams or two systems of government. Once you have that, then you have to find at least two or three points of comparison and use research, facts, and well-organized paragraphs to impress and captivate your readers. Writing the comparative essay is an important skill that you will use many times throughout your scholastic career.

Comparative Essay Outline and Example

How to Develop the Essay Content

• Many comparative essay assignments will signal their purpose by using words such as "compare," "contrast," "similarities," and "differences" in the language of the prompt.
• Also see whether there are any limits placed on your topic.

• The assignment will generally ask guiding questions if you are expected to incorporate comparison as part of a larger assignment. For example: "Choose a particular idea or theme, such as love, beauty, death, or time, and consider how two different Renaissance poets approach this idea." This sentence asks you to compare two poets, but it also asks how the poets approach the point of comparison. In other words, you will need to make an evaluative or analytical argument about those approaches.
• If you're unclear on what the essay prompt is asking you to do, talk with your instructor. It's much better to clarify questions up front than discover you've written the entire essay incorrectly.

• The best place to start is to write a list of things that the items you are comparing have in common as well as differences between them. [3] X Research source

• You may want to develop a system such as highlighting different types of similarities in different colors, or use different colours if you are using an electronic device.
• For example, if you are comparing two novels, you may want to highlight similarities in characters in pink, settings in blue, and themes or messages in green.

• The basis for your comparison may be assigned to you. Be sure to check your assignment or prompt.
• A basis for comparison may have to do with a theme, characteristics, or details about two different things. [7] X Research source
• A basis for comparison may also be known as the “grounds” for comparison or a frame of reference.
• Keep in mind that comparing 2 things that are too similar makes it hard to write an effective paper. The goal of a comparison paper is to draw interesting parallels and help the reader realize something interesting about our world. This means your subjects must be different enough to make your argument interesting.

• Research may not be required or appropriate for your particular assignment. If your comparative essay is not meant to include research, you should avoid including it.
• A comparative essay about historical events, social issues, or science-related topics are more likely to require research, while a comparison of two works of literature are less likely to require research.
• Be sure to cite any research data properly according to the discipline in which you are writing (eg, MLA, APA, or Chicago format).

• Your thesis needs to make a claim about your subjects that you will then defend in your essay. It's good for this claim to be a bit controversial or up for interpretation, as this allows you to build a good argument.

How to Organize the Content

• Use a traditional outline form if you would like to, but even a simple list of bulleted points in the order that you plan to present them would help.
• You can also write down your main points on sticky notes (or type them, print them, and then cut them out) so that you can arrange and rearrange them before deciding on a final order.

• The advantages of this structure are that it continually keeps the comparison in the mind of the reader and forces you, the writer, to pay equal attention to each side of the argument.
• This method is especially recommended for lengthy essays or complicated subjects where both the writer and reader can easily become lost. For Example: Paragraph 1: Engine power of vehicle X / Engine power of vehicle Y Paragraph 2: Stylishness of vehicle X / Stylishness of vehicle Y Paragraph 3: Safety rating of vehicle X / Safety rating of vehicle Y

• The advantages of this structure are that it allows you to discuss points in greater detail and makes it less jarring to tackle two topics that radically different.
• This method is especially recommended for essays where some depth and detail are required. For example: Paragraph 1: Engine power of vehicle X Paragraph 2: Engine power of vehicle Y Paragraph 3: Stylishness of vehicle X Paragraph 4: Stylishness of vehicle Y Paragraph 5: Safety rating of vehicle X Paragraph 6: Safety rating of vehicle Y

• This method is by far the most dangerous, as your comparison can become both one-sided and difficult for the reader to follow.
• This method is only recommended for short essays with simplistic subjects that the reader can easily remember as (s)he goes along. For example: Paragraph 1: Engine power of vehicle X Paragraph 2: Stylishness of vehicle X Paragraph 3: Safety rating of vehicle X Paragraph 4: Engine power of vehicle Y Paragraph 5: Stylishness of vehicle Y Paragraph 6: Safety rating of vehicle Y

How to Write the Essay

• Body paragraphs first . Work through all that information you've been compiling and see what kind of story it tells you. Only when you've worked with your data will you know what the larger point of the paper is.
• Conclusion second . Now that you've done all the heavy lifting, the point of your essay should be fresh in your mind. Strike while the iron’s hot. Start your conclusion with a restatement of your thesis.
• Intro last . Open your introduction with a "hook" to grab the reader's attention. Since you've already written your essay, choose a hook that reflects what you will talk about, whether it's a quote, statistic, factoid, rhetorical question, or anecdote. Then, write 1-2 sentences about your topic, narrowing down to your thesis statement, which completes your introduction.

• Organize your paragraphs using one of the approaches listed in the "Organizing the Content" part below. Once you have defined your points of comparison, choose the structure for the body paragraphs (where your comparisons go) that makes the most sense for your data. To work out all the organizational kinks, it’s recommended that you write an outline as a placeholder.
• Be very careful not to address different aspects of each subject. Comparing the color of one thing to the size of another does nothing to help the reader understand how they stack up. [15] X Research source

• Be aware that your various comparisons won’t necessarily lend themselves to an obvious conclusion, especially because people value things differently. If necessary, make the parameters of your argument more specific. (Ex. “Though X is more stylish and powerful, Y’s top safety ratings make it a more appropriate family vehicle .”)
• When you have two radically different topics, it sometimes helps to point out one similarity they have before concluding. (i.e. "Although X and Y don't seem to have anything in common, in actuality, they both ....”)

• Even the best writers know editing is important to produce a good piece. Your essay will not be your best effort unless you revise it.
• If possible, find a friend to look over the essay, as he or she may find problems that you missed.
• It sometimes helps to increase or decrease the font size while editing to change the visual layout of the paper. Looking at the same thing for too long makes your brain fill in what it expects instead of what it sees, leaving you more likely to overlook errors.

Expert Q&A

• The title and introduction really catch the reader's attention and make them read the essay. Make sure you know how to write a catchy essay title . Thanks Helpful 6 Not Helpful 1
• Quotes should be used sparingly and must thoroughly complement the point they are being used to exemplify/justify. Thanks Helpful 5 Not Helpful 2
• The key principle to remember in a comparative paragraph or essay is that you must clarify precisely what you are comparing and keep that comparison alive throughout the essay. Thanks Helpful 3 Not Helpful 2

• Avoid vague language such as "people," "stuff," "things," etc. Thanks Helpful 4 Not Helpful 0
• Avoid, at all costs, the conclusion that the two subjects are "similar, yet different." This commonly found conclusion weakens any comparative essay, because it essentially says nothing about the comparison. Most things are "similar, yet different" in some way. Thanks Helpful 4 Not Helpful 0
• Some believe that an "unbalanced" comparison - that is, when the essay focuses predominantly on one of the two issues, and gives less importance to the other - is weaker, and that writers should strive for 50/50 treatment of the texts or issues being examined. Others, however, value emphasis in the essay that reflects the particular demands of the essay's purpose or thesis. One text may simply provide context, or historical/artistic/political reference for the main text, and therefore need not occupy half of the essay's discussion or analysis. A "weak" essay in this context would strive to treat unequal texts equally, rather than strive to appropriately apportion space to the relevant text. Thanks Helpful 3 Not Helpful 0
• Beware of the "Frying Pan Conclusion" in which you simply recount everything that was said in the main body of the essay. While your conclusion should include a simple summary of your argument, it should also emphatically state the point in a new and convincing way, one which the reader will remember clearly. If you can see a way forward from a problem or dilemma, include that as well. Thanks Helpful 2 Not Helpful 1

How to Write a Comparison Essay From Start to Finish

Ah, how well I remember the panicked days of frantically googling  “How to write a comparison essay?” and "what is a comparative essay"??" and even in my darkest moments, “what is an essay????”

Also called a comparative essay or a contrast essay , this type of essay is a kind of academic writing where you, the author, analyze any similarity or difference between two subjects. 

These can be ideas, people, events, books, concepts, or other pretty much anything. The main point purpose of a compare and contrast essay is to shed light on the subjects and provide clarity on their relative characteristics.

Usually, you get assigned these as a student, or as a college essay assignment. But sometimes you have a professional writing reason to write them: perhaps writing research paper, maybe as a reviewer or a critic, or if you're a journalist or an academic. It's also a common essay prompt in exams. 

They are actually one of my favorite types of essay writing because they involve a lot of research and giving opinions– which I adore doing.

Let's dive into exactly how to write one of these essays, step by step. For the sake of illustration, I'll be using the essay topic of contrasting and comparing my two cats, Astrid and Chumbo, as an example. 

How sweet are these two!

Step Zero: Laying the groundwork: Pick two topics

(You can skip this if you already have topics selected.)

Part of the fun of any good research paper is selecting what you're going to compare and contrast. These are your main two goals:

Stay on target 

Make sure you're not trying to compare apples to oranges. 

The subjects you choose to compare should be relevant to the context or purpose of your essay. If you're writing for a literature class, pick two novels, or two characters. If you're in biology class, pick two separate evolutionary theories or two famous researchers. 

Your subjects don't have to be identical, but they should have enough in common to warrant a comparison – hence the essay. For instance, comparing two different genres of music can be insightful, but comparing music to a type of food might be too disparate unless you have a very specific and unique angle in mind.

Tip: I find it useful to outline my essay before I start my writing process, just to make sure I'll have enough to compare and contrast on. If you're hesitating, go ahead and follow the steps in an essay outline format, rather than writing the whole thing.

If you're really struggling, you can use a Venn diagram to visually understand the difference and similarities between your topics before writing anything. 

Step One: Begin at the beginning

Every essay needs an introduction, and a compare and contrast essay is no different. Your comparative essay introduction should include:

An introduction of each topic. Briefly explain to your reader what each topic is. 

A thesis statement . This is where you'll spoil the ending and explain which of the two topics you prefer best, and why, or explain why you're comparing or contrasting the two topics. 

For example, my essay introduction could be something like:

“Since getting my two cats, Astrid and Chumbo, people have often asked me which my favorite is. Astrid is smaller, more cuddly, but also more anxious. Conversely, Chumbo is large and in charge – but not as affectionate.  In this essay, I'll compare and contrast the two cats.” 

The first sentence is my thesis statement, and the next statement shows a brief intro of each topic for my contrast essay.

Writing a good thesis statement

Your main goals: be clear, tell your readers what they should take away from all your research, and be the heart of your essay.

Here are some examples:

Both Darwin's theory of evolution and Lamarck's theory of evolution provide insights into the development of species, but they differ fundamentally in their explanations of trait inheritance.

While both '1984' by George Orwell and 'Brave New World' by Aldous Huxley depict dystopian futures, they differ significantly in their portrayal of individual freedom and the means of societal control.

You can see that these are specific, direct, and let you build on these to draft your contrast essay to completion.

Step Two: Research time.

I remember when I first wrote my very first contrast essay. We were assigned to write a comparison between sea and tree octopodi.

Hilariously, if you google Tree Octopus, you do get a hit. But it's all fake information, created to help teach students not to rely on everything they read on Google (or ChatGPT, more probably in these days). 

For your important textual evidence – AKA the specific details, quotes, facts, or information from a text (like a book, article, or document) that you use to support the details in your essay – you want something a little more reliable. 

Where will you find the information you need for this contrast essay? Here are my three tips to stay sharp and make sure you're only writing based on real, trustworthy info:

Start with Scholarly Databases: Platforms like Google Scholar, JSTOR, or PubMed have loads of academic papers and articles. 

Use Libraries: Physical and online libraries have curated collections of books, journals, and more. Librarians are also an excellent resource to ask for help or direction.

Evaluate Online Sources: Not all online sources are created equal (as we've seen). Check the author's credentials, the publication date, and the reputation of the website or publication. 

Step Three: Pick your poison. 

Luckily for you, there are two pretty widely accepted methods of writing a comparative essay: the Block Method and the Point-by-Point Method. 

Block Method

With this method of writing, each of your two topics gets its own contrasting section, or block. You'll first write a sentence introducing your two topics, like, “In this essay, I will compare and contrast Astrid and Chumbo.” 

This is known as your topic sentence .

Then, dig into Topic A, detail by detail, each housed in a body paragraph. After that, you'll explore your second subject, by the same points, paragraph by paragraph. 

For example, my contrast essay could compare Astrid and Chumbo like this:

Topic A: Astrid.

Physical appearance: slender, long, orange and white fur, pink nose

Personality: nervous, goblin-like, cuddly

Likes and dislikes: Loves tuna, cuddles. Hates being alone, dogs.

Topic B: Chumbo

Physical appearance: chunky, floofy, big

Personality: friendly, clownish.

Likes and dislikes: Loves chicken, going outside. Hates rain.

You can see how I contrast the two topics by section.

By contrast, a point-by-point essay is structured by individual points, rather than topic. Each paragraph should cover one argument for both topics.

For example, in my hypothetical Astrid vs Chumbo compare and contrast essay, I might structure it like this: 

Item A: Physical appearance

Astrid: slender, long, orange and white fur, pink nose

Chumbo: chunky, floofy, big

Item B: Personality…

And so on for each point. This allows you to highlight each similarity and difference, even very subtle differences, to better effect.

When should you use each type of essay structure?

Each essay type has its place, though I prefer the PbP method almost always for an entire essay, and only use the Block Method if I'm including a section on differences inside a difference kind of essay, such as a reflective essay or a narrative essay. For lengthy essays, the PbP is clearest.

P-b-p method:

Use this one for deeper, more detailed essays where you don't want your reader losing track of where they are in a longer paragraph.

Here's a contrast essay example that uses this method on Netflix vs Hulu. 

Block method: 

By comparison, use this one when you want to compare things on a more casual level, or if you're only writing a short section to contrast two topics. 

Here's a contrast essay that uses the block method, looking at the difference between certain drugs.

Step Four: The comparison or contrast touches

One of the criterion of writing that distinguishes this essay from other kinds are the transitional words used throughout.

Here's a list of some of the best transition words to use:

Comparison Transition Words:

in comparison

in the same way

equivalently

in a similar manner

"Astrid is a very loyal cat, in that she never leaves my side. Comparably , Chumbo is not as physically snuggly, but he will almost always be in the same room as me."

Contrast Transition Words :

in contrast

on the contrary

on the other hand

“In terms of size, Chumbo is a hefty 22.4 pounds, whereas Astrid is a daintier 12.3 pounds.”

Step Five: Bring it home.

Last but not least, you'll want to write a comparative essay conclusion repeating either your learned opinion on the better of the two, or explaining what the reader should take away.

Normally, writers find it easiest to simply reword their thesis statement, highlight some of the most compelling reasons why, and call it a day.  

“In conclusion, Astrid and Chumbo are both superb cats, each with their own merits. Astrid is snugglier and more affectionate, while Chumbo is the more handsome of the two, and has a goofier personality.” 

There should not be any new information in the conclusion. 

And you're done! You've written your essay like an absolute champ. Hand it in and congratulate yourself on a job very well done. 

FAQ Section

Still have questions? Here's the FAQ section.

How long should a comparison essay be?

As long as it needs to be! If you're in high school, it's probably on the shorter end - 300 to 500 words or so. If you're in college, it's probably closer to 1000-2000 words. If it's a professional assignment, you (or your boss) knows better than me.

Can I compare more than two topics in one essay?

Certainly. For the block method, just add another block, repeating the same items per block. For the PbP method, simply include the information on your third (or nth) topic per point.

What if I can't find enough similarities or differences?

Then that means you either haven't done enough research, or you didn't pick good topics. Go back to the drawing board, dig through some more papers or articles on the subject, and try again.

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 Hamlet and 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:

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.

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

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 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.

Comparative Essays

Writing a comparison usually requires that you assess the similarities and differences between two or more theories, procedures, or processes. You explain to your reader what insights can be gained from the comparison, or judge whether one thing is better than another according to established criteria.

How to Write a Comparative Essay

1. Establish a basis of comparison 

A basis of comparison represents the main idea, category, or theme you will investigate. You will have to do some preliminary reading, likely using your course materials, to get an idea of what kind of criteria you will use to assess whatever you are comparing. A basis of comparison must apply to all items you are comparing, but the details will be different. 

For example, if you are asked to “compare neoclassical architecture and gothic architecture,” you could compare the influence of social context on the two styles.  

2. Gather the details of whatever you are comparing 

Once you have decided what theme or idea you are investigating, you will need to gather details of whatever you are comparing, especially in terms of similarities and differences. Doing so allows you to see which criteria you should use in your comparison, if not specified by your professor or instructor. 

• Appeal to Greek perfection
• Formulaic and mathematical
• Appeal to emotion
• Towers and spires
• Wild and rustic
• Civic buildings

Based on this information, you could focus on how ornamentation and design principles reveal prevailing intellectual thought about architecture in the respective eras and societies.

3. Develop a thesis statement 

After brainstorming, try to develop a thesis statement that identifies the results of your comparison. Here is an example of a fairly common thesis statement structure: 

e.g., Although neoclassical architecture and gothic architecture have [similar characteristics A and B], they reveal profound differences in their interpretation of [C, D, and E]. 

4. Organize your comparison  

You have a choice of two basic methods for organizing a comparative essay: the point-by-point method or the block method.  

The point-by-point method examines one aspect of comparison in each paragraph and usually alternates back and forth between the two objects, texts, or ideas being compared. This method allows you to emphasize points of similarity and of difference as you proceed. 

In the block method, however, you say everything you need to say about one thing, then do the same thing with the other. This method works best if you want readers to understand and agree with the advantages of something you are proposing, such as introducing a new process or theory by showing how it compares to something more traditional.

Sample Outlines for Comparative Essays on Neoclassical and Gothic Architecture 

Building a point-by-point essay.

Using the point-by-point method in a comparative essay allows you to draw direct comparisons and produce a more tightly integrated essay.

1. Introduction

• Introductory material
• Thesis: Although neoclassical and gothic architecture are both western European forms that are exemplified in civic buildings and churches, they nonetheless reveal through different structural design and ornamentation, the different intellectual principles of the two societies that created them.

2. Body Sections/Paragraphs

• Ornamentation in Text 1
• Ornamentation in Text 2
• Major appeal in Text 1
• Major appeal in Text 2
• Style in Text 1
• Style in Text 2

3. Conclusion

• Why this comparison is important?
• What does this comparison tell readers?

Building a Block Method Essay

Using the block method in a comparative essay can help ensure that the ideas in the second block build upon or extend ideas presented in the first block. It works well if you have three or more major areas of comparison instead of two (for example, if you added in a third or fourth style of architecture, the block method would be easier to organize).

• Thesis: The neoclassical style of architecture was a conscious rejection of the gothic style that had dominated in France at the end of the middle ages; it represented a desire to return to the classical ideals of Greece and Rome.
• History and development
• Change from earlier form
• Social context of new form
• What does the comparison reveal about architectural development?
• Why is this comparison important?

A comparison essay compares and contrasts two things. That is, it points out the similarities and differences (mostly focusing on the differences) of those two things. The two things usually belong to the same class (ex. two cities, two politicians, two sports, etc.). Relatively equal attention is given to the two subjects being compared. The essay may treat the two things objectively and impartially. Or it may be partial, favoring one thing over the other (ex. "American football is a sissy's game compared to rugby").

The important thing in any comparison essay is that the criteria for comparison should remain the same; that is,  the same attributes should be compared . For example, if you are comparing an electric bulb lamp with a gas lamp, compare them both according to their physical characteristics, their history of development, and their operation.

Narrow Your Focus (in this essay, as in any essay). For example, if you compare two religions, focus on  one  particular aspect which you can discuss in depth and detail, e.g., sin in Buddhism vs. sin in Christianity, or salvation in two religions. Or if your topic is political, you might compare the Conservative attitude to old growth logging vs. the Green Party's attitude to old growth logging, or the Conservative attitude to the Persian Gulf War vs. the NDP attitude to the same war.

Each paragraph should deal with only  one idea  and deal with it  thoroughly . Give  adequate explanation  and  specific examples  to support each idea. The first paragraph introduces the topic, captures the reader's attention, and provides a definite summary of the essay. It may be wise to end the first paragraph with a thesis statement that summarizes the main points of difference (or similarity). For example, "Submarines and warships differ not only in construction, but in their style of weapons and method of attack." This gives the reader a brief outline of your essay, allowing him to anticipate what's to come. Each middle paragraph should begin with a topic sentence that summarizes the main idea of that paragraph (ex. "The musical styles of Van Halen and Steely Dan are as differing in texture as are broken glass and clear water"). An opening sentence like this that uses a  metaphor  or  simile  not only summarizes the paragraph but captures the reader's attention, making him want to read on. Avoid a topic sentence that is too dull and too broad (ex. "There are many differences in the musical styles of Van Halen and Steely Dan").

VARY THE STRUCTURE

The  structure  of the comparison essay may vary. You may use  simultaneous comparison structure  in which the two things are compared together, feature by feature, point by point. For example, "The electric light bulb lasts 80 hours, while the gas lamp lasts only 20 hours . . . ." Or as in this example (comparing two American presidents):

Consider how perfectly Harding met the requirements for president. Wilson was a visionary who liked to identify himself with "forward-looking men"; Harding was as old-fashioned as those wooden Indians which used to stand in front of cigar stores, "a flower of the period before safety razors." Harding believed that statemanship had come to its apogee in the days of McKinley and Foraker. Wilson was cold. Harding was an affable small-town man, at ease with "folks"; he was an ideal companion to play poker with all Saturday night. Wilson had always been difficult of access; Harding was accessible to the last degree. etc.

Don't use simultaneous structure all the way through the essay, however. It becomes monotonous. Use it sparingly. For most of the essay, use  parallel order structure .

In  parallel order structure  you compare the two things separately but take up the same points in the same order. For example, you may spend half a paragraph on "thing A" and the other half of the paragraph on the corresponding characteristics of "thing B." Or, if you have enough material, devote one paragraph to the physical characteristics of an electric bulb lamp, and the next paragraph to the physical characteristics of the gas lamp.

Or say everything there is to say about the electric bulb lamp (its physical characteristics, history of development and operation), followed by everything there is to say about the gas lamp.

For the sake of variety  you may switch to simultaneous comparison at one point  in the essay, and then switch back to parallel order structure for the rest of the essay. In fact, there are many ways to structure a comparison essay; use whichever organization works best for your particular paper. Here are a few sample organizational methods. "A" stands for "thing A" (ex. electric lamp) and "B" stands for "thing B" (ex. gas lamp). Each number (1,2,3, etc.) stands for a different aspect of that thing (ex. physical characteristics, operation, history of development).
