Memorabilia (Xenophon)

"If we were at war and wanted to choose a leader most capable of helping us to save ourselves and conquer the enemy, should we choose one whom we knew to be the slave of the belly, or of wine, or lust, or sleep?"

"ὁρῶ γὰρ ὥσπερ τὰ τοῦ σώματος ἔργα τοὺς μὴ τὰ σώματα ἀσκοῦντας οὐ δυναμένους ποιεῖν, οὕτω καὶ τὰ τῆς ψυχῆς ἔργα τοὺς μὴ τὴν ψυχὴν ἀσκοῦντας οὐ δυναμένους."

"If you clap fetters on a man for his ignorance, you deserve to be kept in gaol yourself by those whose knowledge is greater than your own."

"A man was angry because his greeting was not returned. “Ridiculous!” Socrates exclaimed; “you would not have been angry if you had met a man in worse health; and yet you are annoyed because you have come across someone with ruder manners!”"

"It is a disgrace to grow old through sheer carelessness before seeing what manner of man you may become by developing your bodily strength and beauty to their highest limit. But you cannot see that, if you are careless; for it will not come of its own accord."

"Though pleasure is the one and only goal to which incontinence is thought to lead men, she herself cannot bring them to it, whereas nothing produces pleasure so surely as self-control."
