A conclusion should:
- Stress the importance of the thesis statement
- Give the essay a sense of completeness
- Leave a final impression on the reader
- Answer the wuestion "So what?" Show your readers why the paper was important. Show them that your paper was meaningful and useful
- Synthesize, don't summarize. Don't simply repeat things that were in your paper. They have read it. Show them how the points you made and the support and examples you used were not random, but fit together. Redirect your readers. Give your reader something to think about, perhaps a way to use your paper in the "real" world. If your introduction went from general to specific, make your conclusion go from specific to general. Think globally.
Create a new meaning. You don't have to give new information to create a new meaning. By demonstrating how your ideas work together, you can create a new picture. Often the sum of the paper worth more than its parts.
A conclusion is a proposition inferred. To infer is to draw a conclusion. To infer that X is true, an inference is the conclusion draw from a set of facts or circumstances. Much of the study of logical explores the validity or invalidity of inferences and implication.
