Organized around common rhetorical situations that occur all around us, INVENTING ARGUMENTS shows students that argument is a living process rather than a form to be modeled. The text's prominent focus on invention teaches students to recognize the rhetorical elements of any argumentative situation and apply the tools of argument effectively in their own writing.
This text is one of the best argument books I've used. Besides a wide range of readings, it has a handy section in the back explaining all of the major terms of argument.
On the downside, it does focus most exclusively on the Toulmin model of argument. It also does not contain many long texts.
Still, it does contain a section of Mein Kampf, and what argument text is complete without a little Hitler?
