Book excerpt: A distinctive feature of Philaletheians’ compilations is that headings (and side captions, when available) function as subtitles: when read sequentially, they impart the salient points of the entire compilation. The value of this feature becomes apparent in long and complex analyses, where Contents double as Train of Thoughts. In this book, pages 2-18 provide an outline of the main points, the syllogism of propositions, and further elaborations.
