Protreptic (Exhortation to Virtue)

Protreptic (προτρεπτικὸς λόγος, "the speech that turns toward") is the hortatory speech-act that converts a hearer to the pursuit of philosophy, virtue, and the care of the soul — distinct from, and in the dialogues typically prior to, the instructional delivery of virtue's content. It is Socrates' characteristic public mode: the harangue that reproaches the Athenians for tending wealth and reputation while neglecting their souls, "rousing us as if we'd been sleeping." The (disputed) Clitophon is the corpus's most explicit thematization of protreptic as a distinct act — and its sharpest critique: protreptic supremely turns (προτρέπει) but does not teach (διδάσκει), so the convert it rouses is left without the positive content (what justice is, what it produces) and may, like Clitophon, take that content-question elsewhere.

Key Points

  • Turning vs. teaching. Protreptic re-orients desire toward virtue; it does not state virtue's essence. The Clitophon drives a wedge into exactly this seam: Socrates' exhortations are "extremely effective in turning us in the right direction" (408c), but when the convert asks "what comes next," he receives only the name "justice" or empty predicates ("the beneficial," "the useful") that fit every skill (409a–b).
  • The model: the Euthydemus interludes. Socrates' two protreptic speeches (278e–282d, 288d–292e) — that everyone wants to do well, that this requires wisdom, that we must therefore philosophize — frame and outclass the sophists' eristic display: genuine exhortation to wisdom against verbal combat for victory.
  • The Apology's public harangue. "Are you not ashamed of your eagerness to possess as much wealth, reputation, and honors as possible, while you do not care for nor give thought to wisdom or truth, or the best possible state of your soul?" (29d–e) — the protreptic reproach as the content of Socrates' civic mission.
  • Protreptic elenchus. The (disputed) Alcibiades I shows protreptic and refutation fused: the refutation-machine is subordinated to turning Alcibiades, and lands a positive protreptic result — the pledge to "cultivate justice in myself right now" (135e) — rather than aporia.
  • The critique from inside (the Clitophon). Clitophon charges that Socratic exhortation without delivered content is like "someone who's not a pilot rehearsing a speech in praise of the pilot's skill" (410b) — praise without competence — and announces he will go to Thrasymachus, "who can actually say what justice is." Socrates gives no reply; the dialogue breaks off.

What the Concept Does

  • Effects the precondition of inquiry. One cannot search for virtue while complacently pursuing wealth and honor; protreptic produces the turn that makes the "what is X?" question matter to the hearer.
  • Names a speech-act the dialogues usually leave implicit. Most Socratic conversations contain exhortation without isolating it; the Clitophon and the Euthydemus interludes make protreptic a topic, letting its power and its limit be seen separately.

What It Rejects

  • The sufficiency of exhortation. The Clitophon's whole point is that turning is not teaching — the convert, roused but uninstructed, is "in the way of his attaining happiness" if left there (410e). Protreptic that never hands over content is, by the dialogue's lights, incomplete.

Stakes

Protreptic is the hinge on which the Clitophon turns the elenchus's signature failure into an explicit complaint. The aporetic dialogues enact the failure to define; the Clitophon gives the failure a voice — a "Socratic hero" who has felt the protreptic charge and demands the missing content. Read forward, this is the demand the Republic (where Clitophon reappears beside Thrasymachus in Book I) sets out to satisfy from Book II on: a positive account of justice and its work. Protreptic thus marks the boundary between Socratic turning and Platonic doctrine — the place where exhortation must be completed by a theory.

Connections

  • contrasts with elenchus — both fall short of positive doctrine but differently: the elenchus refutes a claimant's definition; protreptic exhorts a hearer toward virtue. The Clitophon charges that together they turn-and-refute without ever delivering the content.
  • shares mechanism with rhetoric — protreptic is psychagōgia, soul-leading persuasion; the Clitophon's "praising the pilot's skill" charge pointedly assimilates Socratic exhortation to mere encomium, the more so because the convert's destination is Thrasymachus, a teacher of rhetoric.
  • requires socratic-intellectualism — protreptic presupposes that everyone wants the good and lacks only the wisdom to secure it (Euthydemus 278e–282d); it exhorts toward the knowledge intellectualism makes virtue be.
  • is a case of the constructive turn in the Alcibiades I — protreptic subordinating the elenchus to a positive result (135e), the counterpart to the Clitophon's complaint that the result is missing.

Open Questions

  • Is the Clitophon's complaint a genuine indictment of Socratism (exhortation is all Socrates has) or a staged demand that the Republic answers? The unanswered ending — Socrates' silence — is engineered to keep both readings open; its disputed authorship sharpens the question.
  • Does Plato hold that protreptic can be completed by instruction (the Republic), or that the turn toward virtue is always prior to and separable from any deliverable content?
