Elements of Thinking in Principles--Craig Biddle
The class is meant to give students an overview of what it takes to think in principles. At this, it succeeds admirably. The class covers the following topics: naming your primaries, excluding the middle, thinking in terms of essentials, minding your hierarchy of knowledge and values, and keeping context.
All of the topics are interesting, and well-integrated to the theme of thinking in principles. For instance, take the section on excluding the middle. He explains what the law of excluded middle--a restatement of the law of identity in terms of "either-or", i.e. either a principle is adhered to, or it is not--and its value for thinking in principles, the biggest of which (in my mind) is how it clarifies "degrees" of principle adherence. Mr. Biddle's statement on that: the law of excluded middle tells you there are no "degrees" of adhering to a principle, only degrees of principle violation. Living in a mixed economy? Your rights are not being upheld (you either uphold a principle or not), they are just being violated less than in a communist dictatorship.
Also of note in that section is the discussion on slippery slopes. I think anyone who hears it will learn something, and be well-armed against its abuse and overuse.
Other sections with new and extremely helpful insights are the ones on primaries and hierarchy. Pay special attention to the parts on proximate fundamentals, and the integration of value hierarchy and knowledge hierarchy.
All sections are well-concretized, and not overly so. And the pace was good for the material. The only rough spots for me were a couple in the essentializing section where I got a bit lost, and there was one example in the talk that didn't resonate with me.
It should also be pointed out that this class is not meant as an introduction for a lay audience. The class definitely assumes familiarity with the philosophy of Objectivism.
All in all, this class was stellar. It and the John Lewis talk were the highlights of the conference for me. Buy it the day it becomes available.
