SVF I.201

Original — Ancient Greek

ἔοικε δὲ καὶ Ζήνων εἰς τοῦτό πως ὑποφέρεσθαι ὁ Κιτιεύς, ὁριζόμενος τὴν φρόνησιν ἐν μὲν ἀπονεμητέοις δικαιοσύνην, ἐν δ' αἱρετέοις σωφροσύνην, ἐν δ' ὑπομενετέοις ἀνδρείαν. ἀπολογούμενοι δ' ἀξιοῦσιν ἐν τούτοις τὴν ἐπιστήμην φρόνησιν ὑπὸ τοῦ Ζήνωνος ὠνομάσθαι.

StoicOs Translation

Zeno of Citium, too, seems to drift somewhat toward this position, defining practical wisdom (phronēsis) in matters of distribution as justice, in matters of choice as temperance, and in matters of endurance as courage. In their defence, they maintain that in these definitions it is knowledge that Zeno called phronēsis.

Context

Plutarch, a Platonist writing about four centuries after Zeno, argues in De virtute morali against the Stoic thesis that virtue is a purely rational condition. In this passage he cites Zeno's definitions of the virtues as evidence that even the school's founder tended toward reducing all virtues to one intelligence. The framing “seems to drift toward” is Plutarch's polemical judgment, not part of the doctrine reported.

Source notes:Greek text verified against H. von Arnim, SVF I (1903), no. 201, p. 49 (scanned page). Plutarch's framing „ἔοικε … ὑποφέρεσθαι“ (“seems to drift toward”) belongs to his own polemic against Stoic virtue-intellectualism; the final sentence reports the defence offered by later Stoics, not by Zeno. Von Arnim cross-references DL 7.161, where Aristo is said not to have introduced a plurality of virtues “as Zeno” did.

What the source actually tells us

This is a later report and paraphrase in Plutarch's wording: the definitions are given in his indirect construction, not quoted from a book of Zeno. What it secures is the schema itself — one phronēsis appearing as justice in distribution, temperance in choice, courage in endurance — with explicit attribution to Zeno. The closing sentence (“in their defence they maintain…”) reports how later Stoics glossed Zeno's word phronēsis as knowledge (epistēmē); that gloss is theirs, not Zeno's.

Philosophical meaning

The famous four virtues are, for Zeno, not four separate skills but one practical intelligence meeting different situations: give each their due and wisdom is called justice; choose well and it is called temperance; hold firm and it is called courage. Virtue is one; circumstances are many. This unity-of-virtue thesis shaped the entire Stoic ethical tradition and its ideal of the sage.

Scholarly uncertainty

The definitions reach us only through Plutarch's hostile paraphrase; their exact original wording and the book they came from are unknown. The neighbouring excerpt (von Arnim's no. 200, from the same Plutarch chapter) contains a lacuna that von Arnim could not fully restore — a reminder of how fragile this stretch of transmission is. Whether Zeno meant strict identity of the virtues or one knowledge with several inseparable aspects was already debated in antiquity.

Practical wisdom

Zeno's schema offers a working test for daily life: in any situation, ask which face wisdom must wear here. Is this a moment of distribution (be just), of choice (be temperate), or of endurance (be brave)? One intelligence, three questions — and the same person answering all three.
