From The Teaching Company. Building Great Sentences: The Writer's Craft along with Argumentation: The Study of Effective Reasoning.
I have listened to the Argumentation series and enjoyed it a great deal. In fact, listening to it persuaded me that structured and rule-bound disputation is an excellent way to get to the heart of things, if not to ultimate Truths.
It is no doubt obvious to readers that I have not yet listened to the Building Great Sentences series.
