Chapter 1 gave a good definition of what an argument is. I found the chapter helpful and full of good examples, especially the one about Gordon Adams and his argument to skip out of college algebra! I also liked the section about Socrates and his contrasting view of the Sophists. Chapter 1 taught me that the goal of an arguement is is to seek truth, not just to win.
By the way, did I do this weblog thing right?
