“The good life is one lived with reason as its guide.”
— Zeno of CitiumCommonly cited paraphrase of Stoic doctrine attributed to Zeno; no verbatim source identified
Commentary
This sentence is a paraphrase of a central Stoic idea, that human flourishing consists in the rational governance of one's life, and it is widely attributed to Zeno in popular anthologies. Its substance accords with the doctrine that living in agreement with nature means living in accordance with reason, a theme that runs through the reported sayings. A. A. Long and D. N. Sedley, in The Hellenistic Philosophers, present reason as the organising principle of Stoic ethics, and they show how the good life follows from the proper use of assent. Brad Inwood's study of early Stoic action explains how reason governs impulse and choice, which gives the paraphrase its philosophical content. Julia Annas observes that such summaries are useful pedagogically but can obscure the technical detail of the doctrine. Malcolm Schofield notes that the Stoic conception of reason was cosmic as well as personal, so that the good life is also a participation in the rational order of the world. Because no verbatim source has been identified, the sentence should be labelled as a paraphrase and not presented as Zeno's own wording.
