Ground your answer in a reading of the text itself. [ANSWER 1] The central argument of Lee Sharks’s “Locating the Dependencies: A Protocol for Testing Whether Biography, Catalogue and Chronology Are Independent Witnesses” is that agreement between historical sources is not independent corroboration if those sources derive from one another—or from a common source. But the essay’s more important methodological point is that dependence must be demonstrated, not inferred from resemblance. The text makes this argument by correcting two earlier versions of Sharks’s own analysis, setting out a three-part test for dependence, applying it to two cases involving the ancient tradition about Aristotle and the Peripatetics, and identifying a further test for circular reasoning in chronology. Its conclusion is deliberately limited: it establishes some textual correspondences, locates possible dependencies, and leaves several historical hypotheses unresolved. [chip: Goodreads] 1. The problem: four witnesses may amount to one In §1, Sharks identifies a problem in the reconstruction of the Peripatetic corpus, the body of philosophical writings associated with Aristotle and his successors. Scholars may use four kinds of evidence: Biography: reports about Aristotle’s life and activities. Catalogue: lists assigning works to particular authors. Chronology: dates or sequences proposed for the development of philosophical texts. Text: the surviving philosophical writings themselves. If all four appear to support the same historical interpretation, their agreement might seem to strengthen the case. But Sharks argues that this inference is justified only if the evidence is sufficiently independent. Suppose a feature in a philosophical text generates a biographical anecdote, which then influences a catalogue attribution and a developmental chronology. The four sources would not constitute four independent confirmations. They would be successive expressions of the same underlying evidence. Sharks puts the point sharply: agreement can be “a property of the derivation” rather than independent corroboration. Yet he immediately qualifies the claim: this is a question to investigate, not a conclusion to assume. Dependence must be demonstrated “case by case and only case by case.” [chip: Goodreads] 2. The method: three separate tests for dependence Section 2 supplies the essay’s principal methodological argument. Sharks proposes three evidentiary requirements, designated Columns A, B and C. A Establish the correspondence Identify exactly what two items have in common. A resemblance such as “a superior and a subordinate” is insufficient if the specific relationship or information in the alleged source cannot be recovered in the proposed derivative. B Establish the direction of borrowing Show which item depends on which. Relevant evidence might include the order of passages in a transmitting text, an explicit attribution to an earlier authority, or a feature in one account that makes sense only if it was borrowed from the other. C Exclude an independent source Rule out the possibility that the two items were transmitted separately from some third source that no longer survives. Sharks identifies this as the hardest requirement and anticipates that the column will often remain empty. The rule is strict: a dependency is established only when all three columns are filled. This distinction between locating and establishing a dependency is crucial. A precise correspondence may identify a promising candidate for investigation, but without evidence of direction and exclusion of independent transmission, it cannot prove borrowing. Sharks is also careful about what follows even after dependence is established. A later text may preserve, distort, invert or erase its source. Demonstrating derivation does not automatically make the original source recoverable from the derivative. 3. The first case: the sphere-count and the tutorship anecdote Sharks applies the protocol to a proposed connection between a philosophical textual correspondence and biographical material involving tutorship, legislation and Callisthenes. The essay identifies an exact textual correspondence between Metaphysics Λ 8 and On First Principles at 5a21–23. The relevant passages concern the explanation of the number of celestial spheres and the adequacy of an explanatory method. This is the strongest level of correspondence in the case. The proposed connection to the biographical material is much weaker. Why the argument fails Column A fails at the relevant level. The textual passages concern a cause and the adequacy of a method. The biographical anecdote concerns a hierarchy of persons and obedience. The general resemblance between superior and subordinate does not preserve enough specific information to establish a source relationship. The direction of dependence is unsupported. Nothing establishes whether the anecdote derives from the textual relation, the text was interpreted in light of the anecdote, or both derive from another tradition. Independent transmission has not been excluded. An independently transmitted account of Alexander’s education remains possible. There is also a more specific objection: the philosophical text appears to reverse the relationship that the proposed derivation would require. The demanding text exercises authority over an account it finds insufficient. If the anecdote transformed that relationship into a tutorship story, the person making the demand should occupy the teacher’s role. In the surviving anecdote, that relationship does not hold. Verdict: the dependency is located, not established. Indeed, the evidence runs against the proposed derivation. The point is not that the anecdote must be independent. It is that the available resemblance cannot establish that it depends on the philosophical text. [chip: Goodreads] 4. The second case: aconite and the direction of dependence The second case concerns the tradition about a philosopher’s death by aconite and an epigram associated with that death. Here, Sharks has a more decisive piece of evidence: the order of the material in Diogenes Laertius. The report of the death occurs first, attributed to Eumelus and accompanied by an age. The epigram follows 996 characters later, within a series of epigrams that Diogenes supplies for the subjects of his Lives. The order, attribution and literary context support the natural reading that the reported death provided the occasion for the epigram. The direction therefore runs against Sharks’s earlier proposal that the pun in the epigram generated the death story. This case produces a different result from the first: The direction of dependence is established against the original claim. The independent-source question remains open: Eumelus is named, but his own source is lost. The claim that the epigram generated the death report is withdrawn. This is one of the essay’s most important demonstrations because it is not simply a failure to prove dependence. It is a case where examining the evidence changes the proposed direction of dependence. Sharks explicitly acknowledges that his earlier version failed to check evidence that was available on the page. The protocol catches the mistake by forcing the reader to distinguish textual sequence from assumptions about how an anecdote originated. [chip: Goodreads] 5. The critique of the “anchored versus unanchored” test In §5, Sharks revisits an earlier hypothesis that divided biographical material into two categories: Anchored material: biographical claims that have counterparts in philosophical texts, supposedly making them more stable. Unanchored material: claims without such counterparts, supposedly freer to vary or contradict one another. He now argues that this classification was presented as a test without actually being tested. Three examples illustrate the problem. The lisp. A report that Aristotle lisped, attributed to Timotheus, has no competing version and no demonstrated textual generator. The absence of a counterpart in the philosophical texts does not establish that the report is unreliable. The conflicting ages at death. Eumelus gives Aristotle’s age as 70, while Apollodorus gives 63. This is a genuine contradiction in the tradition, but it does not establish that either report was generated from philosophical texts. The etymologies of “Peripatetic.” Two explanations coexist, with Diogenes marking the second using οἱ δέ, an ordinary formula introducing an alternative report. The existence of the doublet does not itself demonstrate dependence or corruption. The underlying methodological objection is that having a textual counterpart and being evidentially constrained are different properties. An anecdote without a counterpart might have an independent source; an anecdote with a counterpart might have acquired its resemblance through selective interpretation. A genuine test would require researchers to classify biographical claims before consulting the philosophical texts and then measure the stability of those claims across independent witnesses to the same life. Sharks acknowledges that neither step was performed. 6. Chronology: the essay’s proposed executable test Section 6 turns from the specific historical cases to a broader problem of circular reasoning. Suppose a scholar dates a philosophical text by interpreting a particular textual feature, X. Later, that date is cited as independent evidence supporting an interpretation of the same feature, X. The reasoning is circular: the chronology cannot independently confirm an interpretation when that interpretation helped generate the chronology in the first place. Sharks proposes an audit with two steps: Identify the textual features used to generate each proposed date in the developmental literature. Identify where that date subsequently reappears as an independent premise in an argument about those same features. Where the two overlap, circularity is demonstrated for that argument. Where they do not, the chronological evidence may be legitimate. Importantly, Sharks does not reject internally derived chronology altogether. A chronology constructed from one set of features can make independent predictions about features that were not used to construct it. Those predictions can provide genuine evidence. The proposed audit has not yet been carried out. Sharks calls it the principal outstanding task of this line of inquiry. The essay thus supplies a test that can succeed or fail rather than pretending that the existence of circularity has already been demonstrated throughout the scholarship. [chip: Goodreads] 7. What the essay establishes—and what it leaves open The concluding section, “What stands,” is essential to reading the argument correctly. Sharks separates the findings into four categories. Status What Sharks says Established The specified textual correspondences between Metaphysics Λ and On First Principles, including the sphere-count passage, independently of any hypothesis about biography, catalogue or chronology. Located, not established The proposed derivation of higher-level biographical material from those textual correspondences. Withdrawn The claim of a common compiler behind Diogenes Laertius’s biography and catalogue; the categorical claim that each evidentiary level derives from the one above it; the earlier claim about the direction of the aconite story; and the anchored/unanchored classification as a demonstrated test. Open Whether the catalogue’s assignment of the two philosophical texts to two different names derives from the relationship between the texts themselves. The last question is particularly consequential. If the catalogue’s assignment were derived from a perceived relationship between the texts, then the assignment might be evidence that a textual relationship existed, but not independent evidence that two distinct historical authors produced the works. Sharks does not claim to have demonstrated this. The antecedent of the argument remains unproved. 8. The reflexive argument: the author’s own method must be tested The final methodological point appears in §8. Sharks observes that three successive versions of the essay overclaimed: each replaced a refuted claim with a structurally similar one and treated the replacement as demonstrated. He argues that this is not merely a lapse in care. It is a predictable risk when the same person proposes the hypothesis, selects the evidence and judges whether it fits. The essay therefore turns its protocol on its own history. Its second case reveals a directional error that the author could have detected from the text but did not, because the available evidence contradicted the argument he wanted to make. This self-correction is part of the substance of the essay, not just an autobiographical aside. The method must apply to the investigator’s own reasoning as rigorously as it applies to ancient sources. Overall assessment The essay makes three connected arguments. First, agreement among biography, catalogue, chronology and philosophical text is not automatically cumulative evidence: the sources may be dependent. Second, dependence requires more than resemblance. It requires a specific correspondence, evidence of direction and an attempt to exclude independent transmission. The distinction between a located dependency and an established one prevents hypotheses from quietly becoming historical facts. Third, methodological restraint must apply even when the proposed theory is attractive. The aconite case demonstrates how an apparently persuasive explanation can collapse when the actual textual order is examined, while the chronology section shows how the same problem can arise in scholarly reasoning. The essay’s strongest conclusion is consequently not that Aristotle’s biographical tradition is dependent, or that the catalogue is derived from philosophical texts. It is that the independence of these witnesses is an empirical question whose answer must be established separately for each proposed relationship. That restraint is the essay’s governing principle: it preserves what the evidence supports, withdraws what it does not, and leaves genuinely unresolved questions open to further testing.
