There are no hard and fast rules for constructing an argument's conclusion or that mandate what it should contain. Nevertheless, your conclusion should close out the presentation of your evidence in a clear, logical and thoughtful manner and leave the audience with some credible semblance that you have followed through on or fulfilled the promise of your introduction.
If the argument is open-ended, the conclusion should remind the audience of the specifics of the issue being argued, the position you have taken and give them something new to consider. If it is close-ended, it should justify your position. The conclusion is the place to pound home the central points of your argument and persuade the audience that, "given the evidence," your case is indisputable.
Depending on what message you most want to leave your audience with, you may want to conclude using one or more of the following strategies:
- Reflecting Introduction
- Summarizing Key Points
- Logical Synthesis
- Evaluating the Solution
- Call to Action
- Emotional and Ethical Appeals
