Chapter 2
-
In this final lecture of chapter 2, we cover three more fallacies of clarity plus the “golden rule” for dealing with ambiguities. I also offer some advice on how to make a study guide for this or any other course.
-
In this lecture, we cover our first widely recognized fallacy: equivocation. Along the way, we also cover the general topic of fallacies, and why there is no universally recognized list of them. Finally, we cover the extremely important principle of “hermeneutical generosity.”
-
Turning from concepts to the terms that we use to communicate them, we learn two more ways to analyze whether we really know what we’re talking about.
-
We round out our discussion of the basic properties of all concepts by discussing two fundamentally different ways of understanding what a concept means: intension and extension.
-
The third important property of all concepts is their universality. But what does that mean, and just how does it work? Here are three different proposals for solving “The Problem of Universals,” as this mystery has become known over the past 2500 years.
-
We’ve learned that our first act of the mind, simple apprehension, leaves us with concepts we use to make sense of the world around us. How? It’s time for a deeper dive on the concept of a concept.
