Content changes: Chapters 1, 3-6, 10-12

From book blurb:
Chapter 1 has been completely overhauled: it is now simpler and shorter, and includes an important new distinction between persuasion and argumentation.
Coverage of informal fallacies, including nationalism, scapegoating, and guilt-tripping, has been expanded.
In Chapter 3, emphasis on necessary conditions of credibility, rather than sufficient conditions, makes the material more useful.
New exercises and examples throughout reflect the current political context.

Chapter 12 with Nina Rosenstand and Anita Silvers.

New features:
The Top Ten Falacies of All TIme (Appendix 2)
