Differences in the new versions of the Logic texts?

Mr. Nance,

How different is the 2006 version of introductory & intermediate logic to the most recently published version? My friend is selling it, but I need it for Classical Conversations next year and want to make sure it’s close enough to being the same.

And what about the DVDs?

Thanks for your time


The Introductory Logic student text just has cosmetic differences between the fourth and fifth editions: a nicer cover, reformatted style. Most of the improvements are in the additional materials: suggested lesson plans, notes to the teacher, additional tests and quizzes. But the student texts are essentially the same.

Not so with Intermediate Logic. In addition to similar cosmetic changes to the student text and similar additional materials, the student text also has two completely new units, both showing how the tools learned can be applied to real-life, but in different ways. One new unit is designed to teach how to use the tools to analyze chains of reasoning found in real writings: Boethius, Augustine, the Bible, and so on. Another new unit introduces Digital Logic, the logic of electronic devices, as a ubiquitous and powerful application of the tools of Intermediate Logic.

The DVDs are quite different, significantly improved, and professionally filmed. The new DVD lessons are much easier to follow and to navigate. After comparing the two, I am frankly embarrassed by the older version of the DVDs. Look HEREĀ for a side-by-side comparison of the videos on YouTube.

Blessings!
