So, you have entered Unit 4! In this unit, you will be applying many of the tools you have learned up to this point to real-life arguments in written texts, texts that present what I call “chains of reasoning.”
This is a tough section, because we are no longer working with artificial arguments meant to teach the tools, but arguments that have been written in actual books from men like the philosopher Boethius, the Apostle Paul, Augustine, Martin Luther, and others.
Here are a few things you will want to note from the DVD for this lesson.
- This is a longer video, almost 50 minutes. Go get some popcorn.
- I help you through the first two exercises, and work all the way through Ex. 28c. You’re welcome.
- Note that on the video, just before the 4 minute mark, I misspoke. I should have said that P ⊃ Q is equivalent to ~Q ⊃ ~P, but I accidentally omit the “not” (what appears on the screen is correct).
- Watch for the clip from the movie “Get Smart” at the very end. The screen will go dark for a moment; don’t let that fool you!
