The beliefs expressed in the videos are not necessarily those of the author, and in some cases conflict with them. They are meant to provide an audio-visual introduction to the reading and spur critical thinking regarding topics within the chapter, and should be viewed with that intention in mind. The videos have been selected by the Troy University Center for Excellence in eTeaching as instructional aids.  The point of the book is to encourage, inspire, demonstrate, and assist more systematic, thorough, logical, clear, and profound thinking about relationships and the concepts involved in them.
