Dear Reader,

The Systematic-Dialectic of Porphyry the Phoenician’s «Isagoge», depicted below, is based upon Porphyry’s explication of Aristotle’s doctrine to the effect that ‘‘‘Genus plus Differences equals Species’’’.

The image pasted-in below is a visualization of an _NQ dialectical meta-model of the [table of] contents of Porphyry’s famed circa 270 C.E. Introduction to Aristotle’s Categories.  That introduction was composed, originally, as a personal letter to a Roman Senator, Chrysaorius, who wrote to Porphyry, asking for Porphyry’s aid in helping Chrysaorius to grasp Aristotle’s theory of categories.  

Porphyry’s short text became a famous one in the Middle Ages, and has remained so since, although eclipsed lately, somewhat, by the massive modern development of ‘ideographical formal logic’, including of modern mathematical logic, e.g., by that of the sentential calculus, of the first order predicate calculus, and, to a lesser extent, of higher-order predicate calculi.

The ‘phonetic text/ideogramic/pictogramic module’ pasted-in below encompasses this meta-model only through step/stage _Ks₃  =  1 --

1.  The first ‘‘‘category’’’ presented in this ‘‘‘systematic-dialectic’’’ method of presentation, mapped by this meta-model, is the super-category – the category of categories, or category about [other] categories -- whose units are mere categories that are of the “Genus” kind. 

2.  The second ‘‘‘category’’’ presented in the ‘‘‘systematic-dialectic’’’ method of presentation mapped by this meta-model is the super-category  -- the category of categories, or category about [other] categories -- whose units are mere categories that are of the ‘‘‘Essential , Specific Differences’’’ kind.

3.  The third ‘‘‘category’’’ presented in this ‘‘‘systematic-dialectic’’’ method of presentation, mapped by this meta-model, is the super-category – the category of categories, or the category about [other] categories -- each of whose units consists of ‘‘‘Essential, Specific Differences’’’, applied to or “added to” a Genus category, and thereby defining a Species category, whose units inhere immanently & implicitly ‘‘‘within’’’ said Genus.  From such Essential Differences divisions of Genera categories into Species categories arise, &, per Aristotle, definitions are expressed, since each definition is composed of a Genus & such Differences.
