Parts of an Argument
Using the Toulmin method requires that we take an argument apart and examine its various elements. This "dissection" allows us to understand the argument more fully, summarize it more accurately, and discuss its effectiveness or ineffectiveness more intelligently than we would have otherwise.
It might be helpful to envision writing the parts of an argument like building a house of cards, in which you work backwards, beginning with the uppermost level (the claim). Each level is balanced precariously on the level beneath it. And in order for an argument to hold up under careful scrutiny, each level must be strong enough to support what is placed on top of it.
