The structural quadruplicities of this title tend to sum up and/or refine upon a number of the principal theories already discussed in books like 'Philosophical Truth' (1991-2) and 'Veritas Philosophicus' (1992), as well as lay the foundation for the next stage of John O'Loughlin's philosophical advance, which was to be purely aphoristic or, more correctly, maximistic, in what were to be several volumes of back-to-back maxims that continue in the eschatological vein characterizing, from a pretty evolved ontological standpoint, much of this book.
