Logic and Language
-
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.

Apologies for my voice here, but I know many Virginia students missed this material earlier this week because of trouble near the American Legion Bridge. This lecture addresses a major theme we will revisit many times throughout the course: the indispensable yet often confounding role played by the language by which we express our thoughts.
