4. Purpose Division and Classification can be used: • To Explain • To Entertain • To Persuade

5. Purpose • To Explain: Division and Classification essays are typically attempting to explain something. In this context, division and classification works on two levels: • First: you are showing how something works. (Ex: the Library of Congress’s method of organizing information) [dividing up tasks into steps] • Second: you are defining, analyzing, and justifying the principle that underlies the system [classifying purposes and results into each of the divisions]

6. Purpose • To Entertain: opportunity to be witty and clever • example: you might concoct an elaborate scheme for classifying fools, determining distinguishing factors for each class, and providing striking examples

7. Purpose • To Persuade: classification and division adds structure and weight to a persuasive essay; • example: comparing several types of health care plans, you point out the decision-governing principles each employs, the overall cost to the individual, the quality or quantity of providers under each plan

8. Audience • What do your readers already know? • How deep must you go with your explanation? • If they already understand the classification system (ex: movie ratings), just provide a brief sketch, and move on. • How might they use this information? • If they will not be using your explanation, but might discuss it later, an informal division or your subject with vivid examples would be appropriate. • If they may need or want to use your system, give careful and strict guidelines, being sure to divide your topic into all its possible classes, illustrating each with concrete examples.

9. Strategies • Divide your subject into major categories that exhibit a common trait • Create any necessary subdivisions • Arrange your categories into a sequence that shows a logical progression. • Define each of your categories by showing how it differs from the other categories and by providing vivid examples.

10. Points to Remember • Determine whether you want to: • Explain an existing system of classification • Create your own system • Divide your subject into smaller categories by applying the same principle of selection to each category. • Make sure that your division is complete by establishing separate and consistent category types. • Arrange your categories in a logical and emphatic sequence. • Demonstrate the significance of your system by calling your reader’s attention to its significance. • Can be done by demonstrating its use to your reader.
