The Toulmin Argument
This argument is based on informal logic; that is, the argument is not strictly limited to claims built on universal truths.  Rather, the argument you present can be based on probability, what the audience is likely to believe, and arguments which appeal to emotion. 

The basic parts of the Toulmin argument that we will deal with are:

a statement of your position on the issue

Modal qualifier:
an admission, often just in a word, that your claim is not necessarily true 100% of the time

the reasons that support your claim

commonly held assumptions as well as why and how  your grounds support the claim--in other words, you will likely need to explain why your examples, illustrations, and facts support the claim

an acknowledgement and response to points of view other than your own (note that there will likely be multiple points of view that are not in agreement with yours)
