For and against essays discuss the advantages and disadvantages of a topic through an introduction, main body, and conclusion. The introduction presents the topic without opinion. The main body has two paragraphs, one arguing for and one against with examples and justifications. The conclusion restates the topic and includes the writer's opinion. The essay should be written formally without strong language or opinions except in the conclusion. Topic sentences introduce each main body paragraph, followed by supporting examples. Quotations, rhetorical questions, and summaries can be used at the beginning or end for effect.
