Comparing and contrasting is a strategy you use all the time in your thinking. In comparing and contrasting things, you come to know them and thus can make judgements and form opinions about them. If you were reading the works of one author, you might find two books that you like and compare them at the same criteria, while contrasting the features of each. We constantly compare and contrast people, places, books, classes, TV shows -the list is endless.
Because comparing and contrasting is so basic to the way we think, it is also a very common type of writing. An executive writes a report comparing a new product to a competitor's product; a student of political science writes a research essay comparing the campaigns of two politicians.
Like all strategies for organisation, comparing and contrasting is the result of the writer's thought and purpose. If you think about two similar objects or ideas, you will naturally compare and contrast them. As a result, you may decide that one is better than the other or that both are equal, and your purpose would be to show the findings of your thoughts.
You can organize a comparative synthesis by first summarizing each of your sources or subjects, and then discussing significant similarities and differences between them. Having read the summaries and become familiar with the distinguishing features of each source, your readers will most likely be able to appreciate the more obvious similarities and differences. In the discussion, your task is to focus on both the obvious and subtle comparisons and contrasts, focusing on the most significant -that is, on those that most clearly support your thesis.
Organization by source or subject is best saved for passages that can be briefly summarized. If the summary of your source or subject becomse too long, your readers might forget the points you made in the first summary as they are reading the second. A comparison-and-contrast synthesis organized by source or subject might proceed like this:
- introduce the paper; lead to thesis
- summarize source/subject A by discussing its significant features
- summarize source/subject B by discussing its significant features
- Write a paragraph (or two) in which you discuss the significant points of comparison and contrast between A & B
- conclusion: summarize points; raise pertinent questions
Instead of summarizing entire sources one at at time with the intention of comparing them later, you could discuss two sources simultaneously, examining the views of each author point by point (criterion by criterion), comparing and contrasting these views in the process. The criterion approach is best used when you have a number of points to discuss or when passages or subjects are long and/or complex. A comparison-and-contrast synthesis organized by criteria might look like this:
- introduce the paper, lead to thesis
- Criterion 1
- discuss what author #1 says about this point; present situation #1 in light of this point
- discuss what author #2 says about this point, comparing and contrasting #2's treatment of the point with #1's; or present situation #2 in light of this point and explain its differences from situation #1
- Criterion 2
- discuss what author #1 says about this point; present situation #1 in light of this point
- discuss what author #2 says about this point, comparing and contrasting #2's treatment of the point with #1's; or present situation #2 in light of this point and explain its differences from situation #1
- Repeat steps 2 for each criterion.
- conclusion: summarize points; raise pertinent questions
Be sure to arrange criteria with clear method; knowing how the discussion of one criterion leads to the next will ensure smooth transitions throughout your paper.
However you organize your comparison-and-contrast paper, keep in mind that comparing and contrasting are not ends in themselves. Your discussion should point somehwere: to a conclusion, an answer to Why bother to compare and contrast in the first place? If your discussion is part of a larger synthesis, point to and support the larger claim. If you write a stand-alone comparison-and-contrast paper ,though, you must somehow -be that implicit or explicit- answer the why bother-question.
Contrast the two World Wars in light of any four or five criterion you think significant. Conclude with observations. What can your comparative analysis teach us?
