Piety (To Hosion / The Holy)

Piety (to hosion / to eusebes — the holy, the pious, godliness) is the virtue the Euthyphro tries and fails to define. Located as "a part of justice — the part concerned with the care of the gods" (12e–13a), it is run through five definitions to aporia. The dialogue is the home of two enduring contributions: the Euthyphro dilemma (is the holy loved because it is holy, or holy because it is loved? 10a) and the essence/property distinction (the god-loved is a mere affect of the pious, "not … what the pious is," 11a–b). The drama is sharp: a self-proclaimed religious expert, prosecuting his own father, cannot say what the holy is — while Socrates, on his way to answer an impiety charge, seeks exactly this knowledge.

Key Points

  • Five definitions, each refuted: (1) "what I am doing now" — an example, not a form (5d–e); (2) "what is dear to the gods" — but the warring gods love and hate the same things (7a–8b); (3) "what all the gods love" — still a property, not the essence, and the dilemma (below) sinks it; (4) "the part of justice that is care (therapeia) of the gods" — but care betters its object, and no act betters the gods (12e–13d); (5) piety as a trading-skill (emporikē technē) of prayer and sacrifice — which circles back to "what is dear to the gods" (14c–15b).
  • Piety as a part of justice (12d): reached by an odd mereology (as the odd is a part of number), the Euthyphro's attempt to locate one virtue within another — a data point for how Plato divides the virtues before the Protagoras collapses them.
  • Ends in aporia (15c–16a): "we must investigate again from the beginning," yet the demand (a single, non-circular, essence-giving form) is sharpened, not abandoned.
  • The unstated positive hint: Euthyphro's last suggestion — piety as serving and assisting the gods in their work — which Socrates "finds enticing," and which the Apology connects to the gods' wanting us "to become as good as possible."

The Euthyphro Dilemma

"Is the pious loved by the gods because it is pious, or is it pious because it is loved?" (10a). The engine is the carried/led/seen analysis (10a–c): a passive-participle predicate ("god-loved") records that a thing is being acted upon, so it is explanatorily posterior — the gods love the pious because it is pious, hence "god-loved" is a consequence of piety, not its essence; identifying them makes the account circular. The dilemma is the locus classicus of theological voluntarism / divine-command theory: bite the bullet and hold an act is pious in virtue of being god-loved (reversing the priority), or keep the priority and concede that god-belovedness cannot constitute piety. It is a permanent fixture of metaethics and philosophy of religion.

What It Rejects

  • Definition by example — citing a true instance (prosecuting a murderer) in place of the eidos.
  • The god-loved as the essence of the holy — a property all-and-only pious things share is still a pathos, not the ousia.
  • Care that betters its object, applied to the gods — the therapeia model fails because no human act improves a god.

Stakes

The Euthyphro is the cleanest exhibit of the "what is X?" demand and a paradigm of the elenchus ending in aporia. Its failure is not idiosyncratic: piety, like courage (Laches) and temperance (Charmides), resists single-virtue definition — evidence for the wiki's thesis that the Socratic definitional project's collapse is a result (see claims#plato-elenchus-fails-to-define-the-virtues). And the dilemma seeds a problem the Euthyphro cannot itself settle: whether piety is an independent virtue with its own standard, or folds into justice / "becoming as good as possible" — the Apology's recasting of serving the gods as the philosophical examined life, where Socrates' mission is the highest piety (see claims#plato-apology-philosophy-as-highest-piety (live claim)).

Connections

  • is a case of socratic-definition — piety is the X in the locus-classicus "what is X?" inquiry (6d–e).
  • contrasts with socratic-intellectualism — the "piety = a part of justice" mereology is the parts-of-virtue picture the Protagoras collapses into one knowledge; Def 4 (piety as knowledge of sacrifice/prayer) is virtue-as-knowledge failing.
  • contrasts with theory-of-forms — Euthyphro 6d–e seeks "the form itself … as a model" but posits no separate Form (a pre-Forms eidos).
  • requires elenchus — the page's content just is the elenchus run on five successive definitions to aporia.

Open Questions

  • Is the "enticing" hint (piety as serving the gods' work) the dialogue's suppressed answer, making the aporia pedagogical, or a genuine dead end?
  • Can piety survive as an independent virtue once the dilemma blocks "god-loved," or must it dissolve into justice? The Euthyphro leaves this open.
