Chapter 14 talks about fallacies. Its a defense for rhetorical logic. It shows us how to use ignorance as proof. If someone doesn't know something or doesn't really know about the topic your arguing about then you can use that to your advantage. Tautology also is a important tactic. Its when the proof and the endings are the same. False choice is when the number of choices your given aren't all the choices available. What I take from this chapter is that you can use someone else's ignorance to win an argument
