Never emulate those who seek to gain by injustice, but cleave rather to those who have suffered loss in the cause of justice; for if the just have no other advantage over the unjust, at any rate they surpass them in their high hopes.This suggests the noble passage on just living in Isoc. 8.34. Cf. Isoc. 4.28 and note. Life beyond this life is a “hope” in Isocrates; what he is sure of is the immortality of fame. See Isoc. 5.134.

Give careful heed to all that concerns your life, but above all train your own intellect; for the greatest thing in the smallest compass is a sound mind in a human body.From Periander. See Stob. . iii. 56: Περίανδρος ἐρωτηθείς, τί μέγιστον ἐν ἐλαχίστῳ, εἶπε, φρένες ἀγαθαὶ ἐν σώματι ἀνθρώπου. Strive with your body to be a lover of toil, and with your soul to be a lover of wisdom, in order that with the one you may have the strength to carry out your resolves, and with the other the intelligence to foresee what is for your good.
