<\/div>\n\n\n\n

The Anonymous Commentary on Plato\u2019s Theaetetus<\/em><\/a> (P. Berol. inv. 9782), a fragmentary Middle Platonist text dated to the 1st or 2nd century AD, provides a detailed, line-by-line exegesis of the dialogue from its prologue through approximately 153d\u2013154b, with additional fragments extending to discussions of dreams, madness, and perceptual errors. Likely originating from an Alexandrian philosophical milieu, the commentary exemplifies the era\u2019s trend toward dogmatic interpretations of Plato, blending exegesis with doctrinal advocacy. It positions itself as a defense of a unified Platonic-Academic tradition, eclectically incorporating (and subordinating) Aristotelian, Stoic, and skeptical elements to Platonist principles. The commentator (Anon.) rejects skeptical readings of Plato, emphasizing recollection (anamnesis<\/em>), metaphysical flux, and assimilation to the divine as core to epistemology.<\/p>\n\n\n\n

Anon. argues that the Theaetetus<\/em> is fundamentally about the essence of \u201csimple and incomposite knowledge\u201d (e.g., cognition of individual theorems in geometry or music), not the criterion of truth or the objects of knowledge. This contrasts with rival Platonists who saw it as addressing the criterion (using it instrumentally for judgment) or delineating what knowledge is not of (sensibles, as in the Theaetetus<\/em>) versus what it is of (Forms, as in the Sophist<\/em>). Instead, Anon. views the dialogue as didactic, not aporetic, aligning it with Plato\u2019s broader metaphysics: knowledge is \u201cright opinion bound by an explanation given by reasoning\u201d (echoing the Meno<\/em>), tested against sensory accuracy, right opinion, and reasoned opinion, culminating in an incomplete but near-complete definition (lacking only the \u201cbond of explanation\u201d).<\/p>\n\n\n\n

The commentary begins with the prologue, dismissing an \u201caffected\u201d alternative version and interpreting the genuine one (starting \u201cJust now, Terpsion\u201d) as a model of ethical \u201cappropriate actions\u201d (kath\u0113konta<\/em>, borrowed from Stoics but rooted in Socratics). It praises Euclid as a \u201cweighty man\u201d for framing the dialogue, avoiding narrative interruptions. Discussions of characters highlight natural traits: Theaetetus embodies rare virtues (e.g., quick learning, gentleness, courage) that may conflict but coexist in exceptional souls. Anon. critiques popular beauty standards, equating true beauty with wisdom.<\/p>\n\n\n\n

A significant portion explicates the mathematical interlude (147c\u2013148d), reconstructing Theodorus\u2019 demonstration of incommensurable \u201cPowers\u201d (squares with oblong-number areas, like 3ft or 5ft, commensurate in plane but not sides with a 1ft square) versus \u201cLengths\u201d (square-number areas, commensurate in both). Anon. extends this to solids, using numbers for clarity and emphasizing universals to encompass infinities\u2014a dialectical principle. This section, with diagrams and proofs, showcases Anon\u2019s use of Aristotelian syllogistic for exegesis, revealing hidden doctrines.<\/p>\n\n\n\n

The midwifery metaphor (148e\u2013151d) is tied to recollection: souls are pregnant with conceptions needing articulation, not implantation. Socrates\u2019 \u201cbarrenness\u201d is relative to teaching others, aligning with divine compulsion for recollection over dogmatism. Anon. addresses appropriation (oikeiosis<\/em>), critiquing Stoics and Epicureans for failing to preserve justice (e.g., unequal appropriation leads to unequal striving). Justice is instead based on \u201clikeness to god,\u201d not natural sympathy, with a shipwreck dilemma refuting Stoic claims.<\/p>\n\n\n\n

Protagoras\u2019 relativism (\u201cman is the measure\u201d) is critiqued via flux: nothing is absolute; all is relative, leading to perception equaling knowledge (tested with wind-coldness examples). Anon. subordinates Heraclitean flux and Empedoclean effluences to Platonism, rejecting Parmenides\u2019 stasis. Fragments critique false perceptions in dreams\/madness, affirming perception\u2019s infallibility under Protagorean assumptions but ultimately refuting it.<\/p>\n\n\n\n

Critically, the commentary is eclectic yet dogmatic, using rival philosophies polemically (e.g., against Stoic virtues or Epicurean atomism) to affirm Plato\u2019s superiority. It employs syllogistic reconstruction to \u201cuncover\u201d doctrines, reflecting Middle Platonism\u2019s harmonizing tendency. However, its denial of a two-worlds epistemology (Forms for knowledge, sensibles for opinion) as explaining the aporia surprises modern scholars, who often see the absence of Forms as key to the dialogue\u2019s inconclusiveness. Anon\u2019s optimism\u2014that the definition is nearly complete\u2014contrasts with aporetic readings. The text\u2019s fragmentary nature limits scope, but its survival offers rare insight into pre-Neoplatonic commentary traditions, blending pedagogy with philosophy.<\/p>\n\n\n\n

Unique Interpretations by Anonymous Not Advocated by Current Platonic Scholars<\/mark><\/h3>\n\n\n\n
<\/div>\n\n\n\n

Based on contemporary scholarship (e.g., Sedley, Bonazzi, Tarrant, Matoso), Anon\u2019s interpretations are often eclectic and Middle Platonist-specific, but many align with or influence later traditions. However, several stand out as distinctive to Anon. in ways not replicated or advocated by modern scholars, who typically emphasize different aspects of Plato\u2019s epistemology, such as the role of Forms in resolving the aporia or the dialogue\u2019s aporetic nature. Modern Unitarians (e.g., Cornford) often see the Theaetetus<\/em> as presupposing Forms, while Revisionists (e.g., Ryle) view it as independent of them; Anon.\u2019s positions diverge uniquely without modern parallels.<\/p>\n\n\n\n

    \n
  1. Rejection of the \u201cObject-Related\u201d Interpretation Without Invoking Forms as the Resolution<\/strong>: Anon. explicitly denies that the Theaetetus<\/em> demonstrates what knowledge is not<\/em> of (sensibles) while the Sophist<\/em> shows what it is<\/em> of (Forms), insisting instead that both dialogues concern the essence<\/em> of knowledge, not its objects (cols. II\u2013III). Modern scholars like Sedley note this as \u201csurprising\u201d because it rejects what many (e.g., Unitarians) see as Plato\u2019s \u201cfundamental insight\u201d\u2014a two-kinds-of-objects epistemology (Forms for knowledge, sensibles for opinion) explaining the aporia. No current scholar advocates this exact denial; instead, they either endorse the object-distinction (e.g., Cornford 1935, Gill\/McCabe 1996) or argue the dialogue stands alone without Forms (Revisionists like Runciman 1962). Anon\u2019s view\u2014that the aporia stems from an incomplete definition (needing only the \u201cbond of explanation\u201d) rather than ontological shortfall\u2014is not championed today, as it downplays Forms\u2019 role in a way modern Platonists find un-Platonic.<\/li>\n\n\n\n
  2. Justice Based Solely on \u201cLikeness to God,\u201d with a Specific Shipwreck Dilemma Refuting Stoic Appropriation<\/strong>: In discussing appropriation (oikeiosis<\/em>) (cols. V\u2013VIII), Anon. critiques Stoics for basing justice on unequal natural sympathy, using a shipwreck scenario (only one survivor) to refute it, and insists Plato grounds justice in divine assimilation, not oikeiosis<\/em>. While modern scholars discuss Plato\u2019s divine likeness (e.g., Sedley 1999 on Theaetetus<\/em> digression), none advocate this precise anti-Stoic formulation as Plato\u2019s intent in the Theaetetus<\/em>, nor use the shipwreck exactly as Anon. does. Contemporary analyses (e.g., Annas 1999) link justice to Forms or virtue-unity, not this eclectic polemic subordinating Stoicism.<\/li>\n\n\n\n
  3. The Theaetetus<\/em> as Exclusively About \u201cSimple and Incomposite Knowledge,\u201d Defined Eclectically with Aristotelian and Zenonian Elements<\/strong>: Anon. defines the dialogue\u2019s scope as simple knowledge (e.g., individual theorems), drawing from Plato\u2019s Meno<\/em> (\u201cright opinion bound by reasoning\u201d), Aristotle (\u201csupposition with proof\u201d), and Zeno (\u201cdisposition in receipt of impressions not modifiable by argument\u201d) (col. XV). Modern scholars (e.g., Chappell 2005, Fine 2014) debate knowledge definitions but do not advocate this hybrid as Plato\u2019s core thesis; they focus on perception, true belief, or logos, without Anon\u2019s eclectic synthesis or restriction to \u201csimple\u201d versus \u201ccomposite\u201d (systematic) knowledge. This Aristotelian-Stoic blend for exegesis is noted as distinctive Middle Platonist (Bonazzi 2008), not mirrored in current advocacy.<\/li>\n<\/ol>\n\n\n\n
    <\/div>\n\n\n\n

    These interpretations reflect Anon\u2019s Middle Platonist context\u2014eclectic yet dogmatic\u2014but modern scholarship finds them idiosyncratic or overly harmonizing, preferring views that highlight the dialogue\u2019s aporia, Forms\u2019 absence, or Socratic inquiry. No tool results show current scholars endorsing these exact positions; instead, they critique or historicize them as non-standard. If none exist, the answer is that all Anon\u2019s key claims have modern parallels or contrasts, but the above are the closest to uniquely unadvocated.<\/p>\n","protected":false},"excerpt":{"rendered":"
