This writing is formatted to facilitate reflective reading on-line. One of the assumptions informing this paper is that for the foreseeable future authors will be unable to predict whether readers are using on-line or hard copy versions of their work, with the consequence that page references are obsolete and a device-independent form of citation is needed. This writing uses numbered paragraphs as the means of referencing locations within the text and anyone who wishes to cite passages within it should use those, which will work regardless of what device, format, or font a reader is using.
