Euthyphro

Author: Plato · Year: c. 4th c. BCE (trans. G.M.A. Grube, Hackett 1997) · Type: dialogue

A short Socratic dialogue staged outside the court where Socrates is to answer Meletus' impiety charge. He meets Euthyphro — a self-proclaimed religious expert who is prosecuting his own father for a laborer's death — and asks him to define the pious (to hosion). Five definitions fall to the elenchus: piety as an instance (prosecuting wrongdoers, 5d–e); as "what is dear to the gods" (self-contradictory, since the gods war over the just and good, 7a–8b); as "what all the gods love" — which triggers the Euthyphro dilemma (the god-loved is a consequence of piety, not its essence, 10a–11b); as the part of justice that cares for or serves the gods (no melioration, no product, 12e–14a); and as a trading-skill of prayer and sacrifice, which circles back to the god-loved (14c–15b). The work ends in aporia — "we must investigate again from the beginning" (15c) — yet sharpens rather than abandons the demand for a single essence-giving form, and exposes the self-proclaimed expert as not knowing what he claims to know.

Core Arguments

  1. Claim: An adequate answer to "what is the pious?" must give the single form (eidos) common to all pious acts — a model (paradeigma) for judging cases — not one or two examples. Because: Euthyphro's first reply names an instance (prosecuting the wrongdoer, 5d–e); Socrates "did not bid you tell me one or two of the many pious actions" but "that form itself that makes all pious actions pious" (6e), usable "as a model" to sort any act. Against: an ostensive, case-based view — one learns piety by paradigm cases, not an essence-formula; the demand for one form presupposes there is one. Location: 5c–d, 5d–e, 6d–e.

  2. Claim: Def 2 — "the pious is what is dear to the gods" (7a) — is self-contradictory given the warring gods. Because: the gods disagree precisely over the just/unjust, beautiful/ugly, good/bad — the subjects no measurement settles, unlike number, size, weight (7b–d) — so the same act is loved by some gods and hated by others, hence "both pious and impious" (8a–b). Against: deny the gods quarrel about ethics (Euthyphro tries this, 8b), or deny polytheism entails conflicting evaluations. Location: 7a–8b.

  3. Claim: Repairing Def 2 to "what all the gods love" (9e) still does not answer the question, and Euthyphro cannot even establish the antecedent. Because: everyone already agrees a wrongdoer must be punished; what is disputed is only who did what and when (8e–9a) — so unanimous divine love cannot certify Euthyphro's particular act. Against: a determinate theology might secure unanimous divine attitudes; the gap is dialectical, not principled. Location: 8b–9e.

  4. Claim (the Euthyphro dilemma): The "god-loved" cannot be the pious, because the two run the order of explanation opposite ways. Because: by the carried/led/seen analysis (10a–c), a thing is "god-loved" because the gods love it — but the gods love the pious because it is pious; so being-loved is a consequence of piety, not what piety is, and identifying them makes the account circular. Against: theological voluntarism / divine-command theory — bite the bullet and hold an act is pious in virtue of being god-loved, reversing the priority. Location: 10a–11a.

  5. Claim: Euthyphro has named an affect/quality (pathos) of the pious, not its essence (ousia). Because: "you told me an affect or quality of it … but you have not yet told me what the pious is" (11a–b); god-belovedness attaches to pious things but does not constitute their piety — extensional coextension ≠ essence. Against: deny the essence/property distinction — perhaps a virtue just is its relational properties. Location: 11a–b.

  6. Claim: Def 3a — piety as the part of justice concerned with the care (therapeia) of the gods (12e–13a) — fails, because care improves its object. Because: horse-breeding benefits horses, hunting tends dogs, cattle-raising cattle; all therapeia "aims at the good and the benefit of the object cared for" (13b) — but no pious act makes the gods better ("By Zeus, no," 13c). Against: equivocation — Euthyphro means deferential service, not melioration. (Piety is first located as "a part of justice," 12d, via the odd-is-part-of-number / shame-is-part-of-fear mereology, 12a–d.) Location: 12d–13d.

  7. Claim: Def 3b — piety as service (modeled on slaves serving masters) — collapses for want of a product. Because: service to doctors yields health, to shipwrights a ship, to generals victory, to farmers food (13d–14a); so service to the gods must aim at some chief product they achieve "using us as their servants" (13e) — which Euthyphro cannot name (he retreats to "many fine things," 14a). Against: piety might be non-instrumental, expressive service with no separable product, so the craft-analogy simply fails to transfer. Location: 13d–14b.

  8. Claim: Def 4 — piety as "a knowledge of how to sacrifice and pray," a trading-skill (emporikē technē) between gods and men (14c–e) — circles back to the already-refuted Def 2. Because: trade is mutual benefit, but the gods derive nothing from us except "honor, reverence, and … to please them" (15a); so the pious turns out to be what is pleasing/dear to the gods — the god-loved again (15b), which Args. 4–5 already refuted. Against: gifts might benefit the giver or the cosmic order without benefiting the gods, breaking the symmetry that forces the circle. Location: 14b–15b.

  9. Claim: The dialogue ends in aporia — "we must investigate again from the beginning what piety is" (15c–d) — yet the demand (a single, non-circular, essence-giving form) is sharpened, not abandoned. Because: each definition gave an example (1), a divided property (2), a backward-explanatory property (4–5), an over-extended craft (6–7), or a circle (8); Euthyphro then "begs off on the excuse of business elsewhere" (15d). Against: a reader may take the unstated hint (piety as justice-toward-the-gods / serving their work) as the dialogue's real, suppressed answer — aporia as pedagogical mask. Location: 11b, 15b–16a.

Key Findings

  • The Euthyphro dilemma. Foundational in metaethics and philosophy of religion: is the pious loved because it is pious, or pious because it is loved (10a)? The carried/led/seen analysis makes "god-loved" explanatorily posterior, so it cannot be piety's essence — the seed of the theological-voluntarism / divine-command debate.
  • Essence vs. property (ousia / pathos). Even a property that all and only pious things possess — being loved by all the gods — fails as a definition (11a–b). Extensional coextension is not essence; a definition must say what makes its instances what they are.
  • The corpus's clearest exhibit of the ti-esti demand. Euthyphro keeps citing true instances ("I told the truth," 6c); Socrates wants the single form usable "as a model" (6d–e). The dialogue shows the form of the "what is X?" question more cleanly than any other — a pre-Forms anchor (cf. theory-of-forms).
  • An aporia that sharpens the demand. Unlike the Sophist or Republic, no positive doctrine is reached; the "result" is the heightened demand plus the exposure of a self-proclaimed expert who "believe[s] you have clear knowledge" (15d).

Concepts Developed

  • piety-to-hosion — to hosion as definiendum: the essence-vs-property (ousia / pathos) distinction, the Euthyphro dilemma (10a–11b), and piety located as a part of justice (12d).
  • socratic-definition — the ti-esti "what is X?" demand: a single form (eidos) usable as a model/standard (paradeigma), not one or two instances (6d–e).
  • elenchus — the refutative method, enacted on five definitions; its self-image is the Daedalus statue whose arguments "will not stay put" (11b–d).
  • aporia — the unresolved closing impasse (15c–16a), distinctively without a recovered positive doctrine.

Concepts Referenced

  • theory-of-forms — 6d–e as a second pre-Forms ti-esti anchor: the eidos-as-model is the Meno-level common standard, not the separated auto kath' hauto Form (same genealogical guard-rail).
  • socratic-intellectualism — the piety-as-a-part-of-justice mereology (12d) and Def 4's piety-as-knowledge, both in friction with the unity-of-virtues thesis.
  • socrates — protagonist; the dialogue supplies the internal anchors (5c–d, 6d–e, 10a–11b, 15c–16a) for his "What is X?" / model-vs-property method.

Key Passages

"that form itself that makes all pious actions pious" (6e) — eidos as cause "using it as a model, say that any action … is pious" (6e) — paradeigma "what is dear to the gods is pious, what is not is impious" (7a) — Def 2 "The same things then are loved by the gods and hated by the gods" (8a) — the contradiction "Is the pious being loved … because it is pious" (10a) — the dilemma "it is not pious because it is being loved" (10d) — order of explanation "the god-loved is not the same as the pious" (11a) "you told me an affect or quality of it" (11b) — pathos vs ousia "they will not stay put" (11b) — the Daedalus motif "the pious is a part of justice" (12d) — the mereology "it aims at the good and the benefit of the object cared for" (13b) — therapeia "Piety would then be a sort of trading skill between gods and men" (14e) — emporikē technē "So the pious is once again what is dear to the gods" (15b) — the circle closes "we must investigate again from the beginning what piety is" (15c–d) — aporia

What's Not Obvious

  • The dilemma's engine is a grammatical observation, not a theological one. The carried/led/seen analysis (10a–c) notes that a passive-participle predicate ("god-loved") records that something is being done to the thing — so "it is not pious because it is being loved" (10d). Being-loved is explanatorily posterior by the grammar of "because," which is exactly why it cannot be the essence (ousia) as opposed to an affect (pathos) — the metaphysical work of the piety-to-hosion distinction is carried by what looks like a remark about syntax.
  • The aporia may be a mask over a suppressed positive answer. Cooper's intro note flags Euthyphro's last live suggestion — piety as "justice in relation to the gods, in serving and assisting them" — as one Socrates "seems to find enticing," tied to the Apology's claim that the gods want us "to become as morally good as possible." So the dialogue's blank ending (cf. aporia) is arguably pedagogical: the demand is sharpened and a hint is planted, not a genuine impasse — leaving open "can piety remain an independent virtue at all, with its own separate standard?"
  • Euthyphro 6d–e is a pre-Forms anchor that the theory-of-forms page should credit. The "form itself … used as a model" is the Meno-level eidos — a single common feature serving as a standard — not the separated, transcendent Form (no auto kath' hauto, no recollection, no two-world separation). It motivates the Forms without yet being them; reading the later metaphysics back into it is the standard anachronism the same guard-rail blocks for the Meno.

Critique / Limitations

The demand for a single form begs the question against an ostensive, case-based account of how piety is learned. The craft-analogy refutations of Defs 3b–4 lean on demanding a separable product (13d–14a) and melioration of the object cared for (13b) — but a non-instrumental, expressive conception of service to the gods plausibly has neither, so the analogy may simply fail to transfer rather than refute the definitions; the move trades on an equivocation between deferential service and beneficial care that Socrates himself half-grants (13c–d). The dilemma exposes the price of theological voluntarism rather than refuting it head-on (a voluntarist can bite the bullet at 10a–11a). Translation flag: Grube renders to hosion as "the pious / piety / godliness"; the standard scholarly rendering is "the holy / holiness" — the definiendum is the same term throughout. Argumentatively the dialogue delivers no definition: its yield is the heightened demand and the method, not an answer.

Connections

  • enacts elenchus — five confident definitions are elicited and refuted in turn; the dialogue is the corpus's cleanest exhibit of the method's full arc to aporia.
  • shares mechanism with plato-meno — both press the ti-esti / single-eidos-as-model demand (6d–e; the Meno's "one form" for virtue against the swarm-of-bees), the same definitional mechanism intra-corpus.
  • contrasts with socratic-intellectualism — Euthyphro divides the virtues (piety a part of justice, 12d) and shows virtue-as-knowledge (Def 4) failing, a friction with the unity-of-virtues thesis the Protagoras later presses.
  • is the condition of intelligibility of theory-of-forms — the "form itself … used as a model" (6d–e) states the ti-esti demand that the separated Forms are later built to answer, without yet asserting their separation.
