Evidence

Use in the book

Socrates asks for things that can be pointed out when comparing productive crafts and mathematics (165e–166a). An identifiable product and an identifiable object are different kinds of demonstration. At 169b he asks Critias first to show the possibility of reflective knowledge and then its benefit. The demand is not fulfilled: Critias' perplexity leads instead to a provisional concession.

At 172c Socrates says he infers a problem from the strange consequences coming into view. This is a diagnostic use of evidence inside an unresolved inquiry, not a claim to final demonstration. At the end Critias says Charmides' submission to Socrates' daily charm will be a tekmērion of his temperance (176b). That proposed behavioral evidence does not repair the unanswered definition. Indeed, its placement invites scrutiny of whether obedience to an authority is adequate evidence of the very virtue they could not identify.

These episodes keep evidence plural: products one can indicate, reasons for suspecting a difficulty, and conduct offered as a sign of character. Treating every “show” as a formal proof would collapse the differences the dialogue exploits.

Translation in this edition

The form apodeixai se is present within Burnet's deletion brackets at 169b and is not translated as accepted text. The English “proof” at 176b renders tekmērion, evidence or a sign; it should not be retrojected as a successful logical demonstration.

ἀποδείκνυμι

Attested: ἀποδεῖξαί (apodeixai). Show or establish; the verb occurs in words secluded by Burnet at 169b and must not be quoted as unqualified accepted text. References: 169b. Lexical identification: lemma: ἀποδείκνυμι. Burnet secludes ἀποδεῖξαί σε at 169b. See Evidence and proof.

ἀποπληρόω

Attested: ἀποπληρώσαις (apoplērōsais). Satisfy fully or convince; the requested demonstration must establish both possibility and usefulness. References: 169c. Lexical identification: lemma: ἀποπληρόω. See Evidence and proof.

δείκνυμι

Attested: δεῖξαι (deixai). To point out or show; Critias asks for visible products of mathematical expertise, and Socrates instead offers to specify each expertise’s object. References: 166a. Lexical identification: lemma: δείκνυμι. See Evidence and proof.

ἐνδείκνυμι

Attested: ἐνδειξαίμην / ἔνδειξαι (endeixaimēn / endeixai). Show or make evident; concerns the charm’s power and the requested account of temperance. References: 156b, 169b. Lexical identification: lemma: ἐνδείκνυμι. See Evidence and proof.

ἐπιδείκνυμι

Attested: ἐπέδειξάς (epedeixas). Display or present; Socrates asks Critias to call Charmides over and introduce him for conversation. References: 155a. Lexical identification: lemma: ἐπιδείκνυμι. See Evidence and proof.

τεκμαίρομαι

Attested: τεκμαίρομαι (tekmairomai). Infer from an indication; Socrates explains why the assumed usefulness of temperance now seems doubtful. References: 172c. Lexical identification: lemma: τεκμαίρομαι. See Evidence and proof.

τεκμήριον

Attested: τεκμήριον (tekmērion). A sign or piece of evidence: Critias treats Charmides’ continued submission to charming as evidence of temperance. References: 176b. Lexical identification: lemma: τεκμήριον. See Evidence and proof.

Use in the book

Socrates labels the Cretan drinking practice a possible tekmērion against those who understand Minos as Zeus' drinking-companion (319e–320a). Its force depends upon additional propositions: Minos enacted the law, enacted what he regarded as fine, and did not privately practice the contrary. Calling it evidence does not eliminate those dependencies.

The greatest sēmeion for Minos' being good and lawful, a good distributor, comes later: his laws are unmoved (321b). The sign connects the exemplary narrative to the earlier craft argument. There, genuine knowers were said not to write different prescriptions about the same things or keep changing their lawful usages (317b). Here endurance is read as the trace of having discovered the truth of what is concerning civic administration. The wording is therefore not merely antiquarian admiration for old institutions. Stability is being connected to the earlier standard of knowledge and correctness.

The direction of the inference deserves attention. From the claim that good knowledge issues in stable prescriptions, the dialogue turns toward identifying good knowledge through the stability of prescriptions. The latter requires that alternative explanations of endurance not defeat the evidential inference. The text neither investigates such alternatives nor supplies an inventory of unchanged Cretan laws. A lexicon can explain why the sign matters without announcing that longevity alone proves justice or truth.

Nor is the companion's acceptance expressed as an exhaustive verification. He says the argument seems reasonable. Socrates follows with “if what I say is true,” and the companion replies that the Cretans appear to use the oldest laws. This graded language matters: the sequence brings agreement, but it does not narrate independent historical research or abolish the difference between plausibility and truth.

The final return to the soul adds a further limit. The lawgivers have been accepted as good, and the stability of their laws cited as evidence; the question what beneficial content is actually distributed to souls nevertheless remains unanswered. A judgment of a lawgiver's standing is not yet a complete account of the operation and object of lawgiving.

Translation in this edition

“Evidence,” “sign,” “reasonable,” and “unmoved” should remain distinct. “The truth of what is” preserves the explicit connection with the earlier definition. “Administration of a city” follows the edition rather than turning oikēsis into a claim about housebuilding or housing policy.

Evidence — τεκμήριον (tekmērion)

τεκμήριον (tekmērion)

Evidence. An indication used to support a conclusion; the drinking law is proposed as evidence against the convivial interpretation of Minos' association. Attested: τεκμηρίῳ (319e). Evidence, plausibility, and the stability of law.

Greatest — μέγας (megas)

μέγας (megas)

Greatest. The superlative ranks the immobility of Minos’ laws as Socrates’ strongest sign of his goodness and discovery; ranking a sign does not make it an independently completed proof. Attested: μέγιστον (321b). Evidence, plausibility, and the stability of law.

More persuasive — πιθανός (pithanos)

πιθανός (pithanos)

More persuasive. Persuasive or credible; Socrates ranks Homer and Hesiod above the tragedians, a comparative assessment of sources. Attested: πιθανώτεροί (318e). Evidence, plausibility, and the stability of law.

Reasonable — εἰκώς (eikōs)

εἰκώς (eikōs)

Reasonable. Likely, fitting or reasonable; the companion's assessment of Socrates' account is not a claim to have independently verified each premise. Attested: εἰκότα (321b). Evidence, plausibility, and the stability of law.

Sign — σημεῖον (sēmeion)

σημεῖον (sēmeion)

Sign. A sign supporting an assessment; the stability of Minos' laws is called the greatest sign that he was a good distributor. Attested: σημεῖον (321b). Evidence, plausibility, and the stability of law.

Truth — ἀλήθεια (alētheia)

ἀλήθεια (alētheia)

Truth. Truth, explicitly linked with what is in the account of Minos' discovery concerning civic administration. Attested: ἀλήθειαν (321b). Evidence, plausibility, and the stability of law.

As being divine (contextual phrase)

320b: ἅτε θείοις οὖσιν. The participial phrase gives the reason as Socrates presents it: the laws benefit Crete and Sparta as divine laws. A causal construction in a speaker's account reports his explanatory claim; it does not independently establish divine provenance. Compare the related “as being divine” language around survival at 318b–c. See Evidence and stability.

If what I say is true (contextual phrase)

321b: εἰ ἐγὼ ἀληθῆ λέγω. Socrates places the next inference under a truth condition immediately after the companion has called his account reasonable. The sequence distinguishes plausibility, truth, and what follows if the account is true. It need not be read as total withdrawal, but it must not be edited out of a presentation of the argument's confidence. See Evidence and stability.

The poetic praise of Aphrodite promises evidence through her works rather than words alone: the union of earth and rain sustains mortal life. The observation is framed by a personified account of nature. Calling it evidence identifies its argumentative function without committing every reader to the speaker’s theological explanation.

Places to read

1. I.9.1The fertility of earth and sky is offered as evidence of Aphrodite’s power.

Translation in this edition

“Evidence” preserves the inferential role; “proof” suits a speaker presenting the case as decisive.

The Square's report of the King's neighbours fails in Lineland because the information is obtainable by hearing. Disappearance proves only disappearance to someone unable to conceive movement beyond his world. The King calls it magic. When the Sphere later inventories the Square's household, the Square likewise notes that a well-connected visitor could have acquired this knowledge by ordinary means. In each case the higher-dimensional teacher mistakes a correct statement about concealed particulars for an unavoidable proof of the means by which he knows them.

The changing circular section appears a stronger experiment. Yet the Square perceives expansion and contraction without understanding their cause. The Sphere has not altered his actual size; the plane intersects different parts of him as he moves. The fact seen and the explanation inferred remain separate. The narrator's comment that the causes were dark even with the facts before him states one of the book's central epistemic difficulties.

Taking a tablet from a locked cupboard excludes some familiar explanations, and touching the Square's interior provides bodily evidence of access beyond his outline. Both acts nevertheless increase terror rather than understanding. The Sphere declares that his explanation alone fits the phenomena, while the pupil imagines a magician. Coercive transportation finally supplies a new standpoint, but even there learning takes time: light, shade, perspective and touch must be coordinated before a Cube becomes recognizable.

After his return, the Square tries to replace testimony about revelation with demonstration, partly to evade a law directed against alleged visitors from another world. His hope is both intellectual and tactical. An argument that anyone can follow seems safer than an exceptional personal story. The failure with his grandson and the limitations of Flatland diagrams show why the substitution is not straightforward.

The trial sharpens the ambiguity. The President demands direction or depiction and rules out mere enumeration. Those demands resemble the Square's own earlier requests, but now operate inside a regime already committed to suppression. Neither the legitimacy of asking for evidence nor the truth of the narrator's experience exonerates the Council's procedure. The novel asks the reader to distinguish the difficulty of persuasion from the institutional decision to punish inquiry.

In this edition

The notes explain geometrical causes without erasing the pupils' experience of uncertainty. References to empirical tests and revelation are interpretive descriptions of Abbott's dialogue, not claims that the book provides a formal proof of all the worlds it imagines.

Convert

Someone persuaded to accept a new belief. The Square offers to become one if the Sphere can measure or indicate the asserted height, linking religious vocabulary with a demand for demonstration. Printed form: convert (§ 162345). See Evidence and demonstration.

Demonstration

A reasoned proof or intelligible showing. The Square hopes to replace legally dangerous testimony about revelation with a geometrical argument others can follow. Printed form: Demonstration (§ 212). See Evidence and demonstration.

Incredulity · § 16

Unwillingness or inability to believe. The Square's diminishing eye-brightness signals doubt, making an internal intellectual response visible within Flatland's bodily conventions. Printed form: incredulity (§ 162345). See Evidence and demonstration.

Juggler

A conjurer or deceptive performer, rather than only someone who tosses objects. The Square uses the explanation to accommodate strange visible effects without accepting another dimension. Printed form: juggler (§ 162345). See Evidence and demonstration.

Lucid

Clear and intelligible. The King demands a lucid description of the new world, exposing the gap between the visitor's confidence and his ability to make an unfamiliar direction understood. Printed form: lucid (§ 14234). See Evidence and demonstration.

Ocular demonstration

A showing directed to the eye. The Sphere expects visible changes in his section to establish their cause, but the Square sees the effects without understanding the new direction. Printed form: ocular demonstration (§ 162345). See Evidence and demonstration.

Proof positive

Supposedly decisive evidence. The visitor announces the changing section as proof positive, but the subsequent failure distinguishes seeing an effect from accepting its explanation. Printed form: proof positive (§ 162345). See Evidence and demonstration.

Retinue

The attendants surrounding an important person. The King dismisses the Square's accurate description of his retinue because the facts need not have been obtained by the impossible sight being claimed. Printed form: retinue (§ 14234). See Evidence and demonstration.

Tablets of accounts

Written records of financial dealings. Removing one from the locked cupboard makes a familiar, identifiable household object into evidence of dimensional access. Printed form: tablets of accounts (§ 172). See Evidence and demonstration.

Dimension implies direction and measurement (contextual phrase)

§162345. “Dimension implies direction and measurement.”

The Square asks for a criterion rather than another prestigious assertion. If the new height is a dimension, he wants it measured or its direction indicated. On the pupil's present terms, the Sphere admits that he can do neither. The demand is therefore more serious than the surrounding comedy of an eye in the stomach may suggest. Yet it is not the last word: a subject confined to a plane may lack the practical access required to satisfy a test that presupposes movement outside it. The passage stages a genuine tension between intelligible evidence and the enlargement of the framework within which evidence is intelligible. Neither credulity nor simple contempt for the request captures its force.

Deeds, and not words, shall proclaim the truth (contextual phrase)

§172. “Deeds, and not words, shall proclaim the truth.”

The declaration promises an escape from verbal misunderstanding. The Sphere will remove a tablet from a locked cupboard and then reach the Square's bodily interior. These deeds certainly disturb the pupil's account of what is possible, but they do not immediately establish the visitor's explanation. Instead they produce fear of a magician and another attack. The contrast between words and deeds therefore fails to settle the deeper problem: an event has to be interpreted, and several interpretations may initially seem possible to someone lacking a new spatial concept. The maxim also conceals an ethical escalation. A demonstration using a household object becomes an invasion of the pupil's body before he can object.

Apparent generation without bodily seeds is an explanandum, not the conclusion that no productive seed exists. Likewise, movements appearing self-originating may be caused by an unseen mover. Ficino explicitly illustrates that problem with iron whose magnet is hidden. An observer's sight of motion does not itself identify the cause. At the same time, the text freely argues from observed order, differing bodily constitutions, and visible effects to invisible souls. A reader should preserve that inferential step rather than presenting the soul as something directly observed.

The discussion of airy and fiery creatures also distinguishes lack of visibility from absence: Ficino attributes it to the lack of sufficient brightness or density for earthly eyes. Claims about visible or touchable daemons are then assigned to Zoroaster and Porphyry. This is a reported explanation of alleged evidence, not independent verification of the creatures.

“Seem,” “appear,” “show,” and “as... believes” are small but substantive qualifications. Removing them can turn an appearance into an established cause or an attributed report into Ficino's direct observation.

errāre / iudicare

errāre / iudicare. Printed forms: errat; iudicant.

To err; to judge. The Platonists infer souls from inward motion; perfect celestial wisdom's lack of deliberative error explains its unvarying operation. References: IV.1.74, IV.1.84. See Seeming and evidence.

mirari / mirabilis

mirari / mirabilis. Printed forms: miraberis; mirabilem; mirabiles.

To wonder; remarkable or wondrous. A rhetorical challenge reduces surprise at celestial souls' efficacy, while wondrous bodily actions function as premises within Ficino's historical account. References: IV.1.19, IV.1.72, IV.2.19. See Seeming and evidence.

perspicere / cernere

perspicere / cernere. Printed forms: cernimus; perspicimus.

To perceive clearly or discern. Brightness, nearness, and density explain visibility; the argument does not equate invisibility with nonexistence. References: IV.1.38. See Seeming and evidence.

signum

signum. Printed forms: signum.

A sign used as evidence for a claim. The twelve zodiacal creatures are a sign of the proposed number; spontaneous inward motion is a sign of interior life. Neither is treated as direct sensory perception of an incorporeal soul. References: IV.1.43, IV.1.69. See Seeming and evidence.
