Xenophon’s Memorabilia 1.6.10
“You appear to think that happiness comes from delicacy and abundance. But I think that wanting nothing is godlike, that wanting as little as possible is next-best, that the divine is the highest goal and next-best the closest thing.”
 ἔοικας, ὦ Ἀντιφῶν, τὴν εὐδαιμονίαν οἰομένῳ τρυφὴν καὶ πολυτέλειαν εἶναι: ἐγὼ δὲ νομίζω τὸ μὲν μηδενὸς δεῖσθαι θεῖον εἶναι, τὸ δ᾽ ὡς ἐλαχίστων ἐγγυτάτω τοῦ θείου, καὶ τὸ μὲν θεῖον κράτιστον, τὸ δ᾽ ἐγγυτάτω τοῦ θείου ἐγγυτάτω τοῦ κρατίστου.
Cicero, Letters to Quintus 25
“I believe that you will anticipate that I didn’t lose those books without some kind of a stomach ache…”
puto enim te existimaturum a me illos libros non sine aliquo meo stomacho esse relictos.
Cicero, Letters to Quintus 24
“Concerning the issue of supplementing your Greek library and trading books in order to acquire Latin ones, I would really like to help get this done, since these exchanges are to my benefit as well. But I don’t have anyone even for my own purposes whom I can trust with this. The kinds of books which are helpful are not for sale and they cannot be procured without a deeply learned person who has a serious work ethic.”
De bibliotheca tua Graeca supplenda, libris commutandis, Latinis comparandis, valde velim ista confici, praesertim cum ad meum quoque usum spectent. sed ego mihi ipsi ista per quem agam non habeo. neque enim venalia sunt, quae quidem placeant, et confici nisi per hominem et peritum et diligentem non possunt.
Bonus Quotes from Cato, Dicta Catonis
“Remember the things you read”
Quae legeris memento.
And never forget this:
Lucretius, De Rerum Natura 5.1430-1439
“The human race, then, labors uselessly and in vain
as we always consume our time in empty concerns
because we don’t understand that there’s a limit to having—
and there’s an end to how far true pleasure can grow.
This has dragged life bit by bit into the deep sea
and has stirred at its bottom great blasts of war.
But the guardian of the earth turns around the great sky
and teaches men truly that the year’s seasons come full circle
and that all must be endured with a sure reason and order.”
Ergo hominum genus in cassum frustraque laborat
semper et [in] curis consumit inanibus aevom,
ni mirum quia non cognovit quae sit habendi
finis et omnino quoad crescat vera voluptas;
idque minutatim vitam provexit in altum
et belli magnos commovit funditus aestus.
at vigiles mundi magnum versatile templum
sol et luna suo lustrantes lumine circum
perdocuere homines annorum tempora verti
et certa ratione geri rem atque ordine certo.
