Some words in Euripides' Hippolytus

As we begin Euripides' Hippolytus, I'll be putting occasional notes here, some strictly philological in nature, others as seems fit.

Three words that come back again and again, with almost hypnotic regularity, are:

sōphrōsunē

From Ancient Greek σωφροσύνη (sōphrōsunē, “soundness of mind, prudence, self control, temperance”) from σώφρων (sōphrōn, “sane, moderate, prudent”) (from σῶς (sōs, “safe, sound, whole”) + φρήν (phrēn, “mind”)) +‎ -σύνη.

Sophrosyne is the subject of Plato's Charmides, and is treated in Book 2 of Aristotle's Nicomachean Ethics.

Phaedra:

εἰσὶ δ᾽ ἡδοναὶ πολλαὶ βίου,

μακραί τε λέσχαι καὶ σχολή, τερπνὸν κακόν, 385

αἰδώς τε. δισσαὶ δ᾽ εἰσίν, ἡ μὲν οὐ κακή,

ἡ δ᾽ ἄχθος οἴκων. εἰ δ᾽ ὁ καιρὸς ἦν σαφής,

οὐκ ἂν δύ᾽ ἤστην ταὔτ᾽ ἔχοντε γράμματα.

Life's pleasures are many, long leisurely talks—a pleasant evil— [385] and the sense of awe. Yet they are of two sorts,1 one pleasure being no bad thing, another a burden upon houses. If propriety were always clear, there would not be two things designated by the same letters.
