"And the explanation of his arguments is three-fold.…" — Diogenes Laertius (#c1524)

Card #c1524IR // #c1524Synthesis

And the explanation of his arguments is three-fold. For first of all, it is necessary to explain what each thing that is said is; secondly, on what account it is said, whether because of its bearing on the principal point, or figuratively, and whether it is said for the purpose of establishing an opinion of his own, or of refuting the arguments brought forward by the other party to the conversation; and thirdly, whether it has been said truly. XXXIX. But since there are some particular marks put in his books, we must also say something about them. × indicates peculiar expressions and figures of speech, and generally any peculiarities of Plato’s style. When doubled it points to the doctrines and peculiar opinions of Plato; ※ when dotted all round, points to some select bits of beautiful writing. When doubled and dotted it indicates corrections of some passages. A dotted obelus indicates hasty disapprovals. An inverted sigma dotted all round points out passages which may be taken in a double sense, and transpositions of words. The Ceraunium[33] indicates a connection of philosophical ideas. An asterisk points out an agreement in doctrine. And an obelus marks the rejection of the expression or of the passage. — Diogenes Laertius, *Lives of Eminent Philosophers*, Book III, Sections XXXVIII–XXXIX, trans. C. D.

Build a bespoke marginal glyph set that separates *stylistic beauty*, *core authorial thesis*, *structural cross-links* (the Thunderbolt), *deliberate ambiguity*, and *spurious/rejected claims*—and always audit a claim in three distinct passes: What does it say? Why is the speaker saying it here (sincerely, figuratively, or as a trap)? Is it actually true?

[Why it matters]

Reading Plato requires a three-step audit (what is said, why/how it is said in context, and whether it is true) assisted by nine marginal symbols placed in elite manuscripts to flag doctrines, style, double meanings, and philosophical links. Diogenes preserves a priceless snapshot of ancient book-technology and Alexandrian philological practice as applied to philosophy (parallel to Aristarchus’s Homeric sigla, likely systematized for Plato by Thrasyllus or Aristophanes of Byzantium). Because newly published Platonic rolls were scarce and leased for money (as Antigonus of Carystus notes at the end of XXXIX), authoritative copies carried a marginal metadata layer of nine critical signs (*semeia*): the *Chi* (×) for lexical/stylistic peculiarity, the *Diplê* or doubled *Chi* for positive Platonic dogma, the dotted *Chi* (※) for anthology-grade prose, the *Antisigma* periestigmenon for double meanings (*amphiboliai*), the *Ceraunium* (thunderbolt) for structural/philosophical concatenation (*agoge*), the *Asterisk* for doctrinal harmony across passages, and the *Obelus* for spurious interpolations. Paired with the threefold hermeneutic rule (literal meaning -> rhetorical/dramatic intent -> objective truth), this turns the scroll into an indexed analytical database. [INTERPRETATION: PRISCA THEOLOGIA / ESOTERIC] [Paratext Note: Yonge (1853), footnote 33, notes simply: "From κεραυνὸς, _a thunderbolt_."] In late antique and Renaissance reception, these marginal glyphs—especially the *Ceraunium* (the thunderbolt marking the hidden chain of philosophical conduction) and the dotted *Antisigma* (marking passages of deliberate double sense)—were viewed as the graphic footprints of the *catena aurea*, the golden chain of initiated readers. Because Plato embeds figurative myths, ironies, and refutative traps alongside high dogma (as the threefold rule warns), an unmarked text is a labyrinth. The sigla function as silent hieroglyphic pointers left by master-scholiasts to show the initiate where the literal crust thins out and the lightning-flash (*ceraunium*) of systematic doctrine connects across seemingly unrelated dialogues.
