Hippias Minor (Lesser Hippias)

Author: Plato · Year: c. 4th c. BCE (trans. Nicholas D. Smith, Hackett 1997) · Type: dialogue

A short, single-bout dialectic in which Socrates pins the sophist Hippias with a paradox welded out of two movements. First, reclassifying the liar from a moral type into a power (dunamis) to speak falsehood at will, Socrates argues that only the knower has that reliable ability — so the truthful expert and the accomplished liar are the same person, and the contrast Hippias drew between truthful Achilles and wily Odysseus collapses. Second, generalizing through every craft, the voluntary error turns out to mark the better agent (the good runner runs slowly on purpose), until justice — classed as power and/or knowledge — yields the unacceptable conclusion that "it's up to the good man to do injustice voluntarily" (376b). Socrates argues only ad hominem, from Hippias' own concessions, and then disavows the conclusion with a single conditional — "if there is such a person" — and a confession that he "waver[s] back and forth" (376c). The dialogue thus runs the craft-analogy of virtue to a reductio and deliberately refuses to discharge it; the exit it never states is the intellectualist one — that no one errs willingly, so there is no such person.

Core Arguments

  1. Claim: Lying is not the work of the ignorant but of a power (dunamis) to speak falsehood at will; one who lacks that power and is ignorant is no reliable liar. Because: Hippias grants that liars are "powerful and intelligent and knowledgeable and wise" in what they lie about, deceiving "by cunning," not "from dimwittedness"; Socrates fixes the entailment — "a person who did not have the power to lie and was ignorant would not be a liar," and "each person who can do what he wishes when he wishes is powerful." Against: equivocation — the ordinary liar succeeds because the victim is ignorant, not because the liar has expert knowledge; "power to deceive" need not be "knowledge of the truth about X." Location: 365d–366c.

  2. Claim: In any craft the expert is the one best able to tell both truth and falsehood; the ignorant person errs only involuntarily and at random. Hence the same person is both truthful and false — "not complete opposites" — and this identity holds across every science, so there is no case of a distinct truthful man and a distinct liar. Because: asked "three times seven hundred," the expert "if he wished to lie" would "always consistently lie," whereas the ignorant person "would often involuntarily tell the truth when he wished to say falsehoods"; reliable false-telling tracks knowledge. Socrates then runs an induction over arithmetic, geometry, astronomy, and Hippias' own polymath crafts (368b): "you will not find" a case where the two come apart — "none exists." Against: this exploits the broad sense of "liar" (a translator's note at 365b glosses it as "one who says what is false, whether or not their intent is to deceive"); uttering a falsehood on demand is not yet deceiving. And the enumerative induction never tests a domain where "true" and "false" are not symmetric outputs of one skill — precisely the domain (justice) targeted next. Location: 366c–369a.

  3. Claim: Applied to Homer, Achilles (truthful) and Odysseus (wily) cannot be opposites; they are "not different … but similar," and Achilles in fact lies on purpose. Because: by the identity-result, "if Achilles was truthful, he also becomes a liar"; Socrates close-reads the Iliad to show Achilles announcing he will sail home and never doing it, even contradicting himself to Ajax and Odysseus. Against: a textual quarrel — Hippias insists the inconsistency is Achilles' "guilelessness," not scheming; the literary evidence under-determines whether he deceives or merely changes his mind under duress. Hippias protests that Socrates is "always weaving arguments of this kind." Location: 369b–371e.

  4. Claim: Hippias' rescue — Achilles lies "involuntarily, forced," Odysseus "voluntary and on purpose" — backfires: in every ability the agent who produces the bad result voluntarily is the better/more skilled one. Because: a relentless induction installs the two-way power — skill is the capacity to produce either outcome at will: the good runner runs slowly on purpose, the good wrestler falls on purpose, "awkwardness, when voluntary, counts toward virtue, but when involuntary, toward worthlessness"; rudder, bow, lyre, and the souls of horse, archer, and doctor all "miss the mark voluntarily" when better. Against: the inference smuggles the bad result into the excellence — being able to fall on purpose is not being a good wrestler in the act of falling — and for some "abilities" (limping feet, dull eyes) the voluntary version is grotesque, signalling the analogy is straining before justice is reached. Hippias' moral intuition resists: the laws "are surely much harsher towards those who do evil … voluntarily." Location: 370e–375c.

  5. Claim: Extended to justice — classed as "either some sort of power or knowledge, or both" — the conclusion is that the more powerful/wiser soul, being best able to do both fine and shameful, does injustice voluntarily; so "it's up to the good man to do injustice voluntarily." Because: if justice is dunamis, "the more powerful soul [is] the more just"; if knowledge, "the wiser soul [is] more just"; either way that soul "was seen to be better and to have more power to do both," hence to do injustice on purpose. Against: the disanalogy made explicit but never resolved — unlike a craft, justice is not a neutral two-way power whose excellence is indifferent between just and unjust outcomes; treating it as one (the suppressed premise) is exactly what makes the conclusion absurd. Location: 375d–376b.

  6. Claim: Socrates disavows the conclusion he has just compelled. Because: he attaches the conditional "that is, if there is such a person" — withholding assent to the very existence of a voluntary wrongdoer — and closes "Nor I with myself, Hippias … I waver back and forth and never believe the same thing." Read as a reductio, the absurd conclusion pressures the craft-analogy of virtue rather than establishing the paradox; the unstated exit is that "no one errs willingly," so there is no such person. Against: read straight, the argument is valid and Hippias never locates the false premise; Socrates supplies only an unargued "if" and a confession of aporia, so the dialogue performs the tension without discharging it. Location: 376b–c.

Key Findings

  • The liar is reclassified from a moral type to a capacity. Once "liar" means "one able to speak falsehood at will," lying routes through expertise, and truthfulness and mendacity collapse into a single knower (367c). This unmarked move is the whole engine of the paradox.
  • The craft-analogy is here a paradox-engine, not a standard of knowledge. Where the Ion and Gorgias wield the technē-model to measure pretenders, the Lesser Hippias pushes it until it self-undermines: modeling virtue on craft entails "the good man" does injustice voluntarily (376b). This is the corpus's clearest case of the technē-analogy turned against itself.
  • The unsoundness for justice turns on an unnamed premise — that a skill is a two-way power (the expert who can produce F can produce not-F at will). Granted without resistance and never defended, it is exactly where a vigilant interlocutor should balk; justice, if "no one errs willingly," is not such a capacity.
  • An elenctic conclusion Socrates himself disavows. The dialogue separates the result of refutation from Socrates' commitments: the valid-looking proof is reached ad hominem and then refused (376c), which tells against any reading that takes elenctic conclusions as Plato's own doctrine.

Concepts Developed

This dialogue introduces no new standalone concept; its original contribution — the craft-analogy of virtue run to a reductio, via the suppressed two-way-power premise and the inversion that makes voluntary wrongdoing the mark of the better agent — is homed on the existing socratic-intellectualism page (updated by the main thread).

  • socratic-intellectualism — the Lesser Hippias looks like a counterexample to "no one errs willingly" (it concludes the voluntary wrongdoer is "the good man," 376b) but is best read as its set-up: a reductio of the craft-model of virtue whose only local exit is to deny that any voluntary wrongdoer exists — which is the intellectualist thesis. Where the Protagoras argues virtue-as-knowledge directly, this dialogue performs the collision between the craft-analogy of virtue and the denial of akrasia, and refuses to adjudicate.

Concepts Referenced

  • socratic-ignorance — Socrates' "I waver back and forth … plainly because I don't know" (372d, 376c) is continuous with the Apology's human wisdom, but staged mid-argument as a request for Hippias to "cure my soul" (372d) — disavowal as a dialectical lever, not just a confession.
  • elenchus — a classic ad hominem elenchus binding Hippias by his own admissions ("arguing only on the basis of assertions Hippias has made"), but unusual in terminating in a conclusion Socrates disavows (376c).
  • aporia — the dialogue ends in acknowledged impasse, but a paradox-aporia (a valid-seeming proof with an unacceptable conclusion), not the definitional aporia that fails to define a virtue.

Key Passages

"a person who did not have the power to lie and was ignorant would not be a liar" (366b) — dunamis as the mark of the liar "each person who can do what he wishes when he wishes is powerful" (366c) — power as at-will capacity "the same person has the most power both to say falsehoods and to tell the truth" (367c) "the same person is both a liar and truthful … not complete opposites" (367c) — the identity paradox "if you find any case in which one person is truthful and another … is a liar … none exists" (368b) — the generalization "if Achilles was truthful, he also becomes a liar … not different … but similar" (369b) — Homer "awkwardness, when voluntary, counts toward virtue, but when involuntary, toward worthlessness" (374b) — the two-way power "isn't justice either some sort of power or knowledge, or both?" (375d) — the dilemma that lets the craft-model capture justice "the more powerful and better soul, when it does injustice, will do injustice voluntarily" (376a) "it's up to the good man to do injustice voluntarily" (376b) — the unacceptable conclusion "the one who voluntarily … does what is shameful and unjust … if there is such a person … the good man" (376b) — the disavowing "if" "Nor I with myself, Hippias … I waver back and forth and never believe the same thing" (376c) — the disavowal

What's Not Obvious

  • One unrepeated conditional carries the whole dialogue. "If there is such a person" (εἴπερ … ἔστι τις, 376b) appears once and withholds Socrates' assent to the very existence of a voluntary wrongdoer. It is the hinge that converts a valid-looking proof into a reductio and a disavowal; read past it, and the dialogue looks like an endorsement of the paradox. The "if" is the intellectualist escape hatch — "no one errs willingly" entails there is no such person — which is why the contribution is homed on socratic-intellectualism.
  • The load-bearing premise is never named or defended. That a skill is a two-way power — the expert who can produce the good result can produce the bad one at will — is installed by the long induction (373c–375c) and granted by Hippias without resistance, then silently transferred to justice (375d). It is the genuine crux: a craft is such a neutral capacity (the doctor who can heal can sicken), but virtue, if no one errs willingly, is not. Diagnosing this is what turns the dialogue from paradox into the limit of the technē-analogy that the Ion and Gorgias otherwise ride as their standard of knowledge.
  • The refutation ends where Socrates' belief does not. The elenchus terminates in a conclusion Socrates explicitly disavows (376c), and mid-argument he reframes his own perplexity as a disease for Hippias to "cure" (372d) — disavowal deployed as a dialectical lever. This separates the elenctic result from Socrates' commitments and is useful evidence on the elenchus page against reading any elenctic conclusion as Plato's own.

Critique / Limitations

The argument is valid, and Hippias never locates the false premise — its force lives in moves left unmarked. The decisive equivocation is the broad sense of "liar" fixed by a translator's note at 365b ("one who says what is false, whether or not their intent is to deceive"): uttering a falsehood on demand is conflated with deceiving, so the morally loaded conclusion rides on a thinner claim. The generalization is an enumerative induction over a controlled sample of crafts, never testing a domain where truth and falsehood are not symmetric outputs of one skill. The conclusion's whole force then lives in an unmarked glide from "good at X" (craft-excellence, agathos peri) to "the good man" (moral excellence, agathos), licensed only by the undefended assimilation of justice to a two-way dunamis. Bibliographic note: the OCR'd raw text carries no inline translator-credit line for this dialogue; "Nicholas D. Smith" is supplied on Cooper/Hutchinson (1997) authority.

Connections

  • requires socratic-intellectualism — the paradox dissolves only on the intellectualist thesis that no one errs willingly: that is what makes "if there is such a person" (376b) a denial of the voluntary wrongdoer's existence rather than an idle hedge.
  • is a case of aporia — but a paradox-aporia (a valid-seeming proof with an unacceptable conclusion, closer to the Sophist's metaphysical impasses), categorically distinct from the definitional aporia that fails to define a virtue; its exit lies outside the text.
  • contrasts with plato-protagoras — where the Protagoras argues that virtue is knowledge and denies akrasia, the Lesser Hippias performs the collision between the craft-analogy of virtue and "no one errs willingly" and leaves it unresolved.
  • enacts elenchus — an ad hominem refutation built strictly from Hippias' concessions that terminates in a conclusion Socrates disavows (376c), separating elenctic result from his own commitments.
  • contrasts with plato-gorgias and plato-ion — there the technē-model is the standard of knowledge against which pretenders are measured; here the same craft-analogy is the engine of an absurd conclusion.
