Anabasis, 2.6.6:
“Now such conduct as this, in my opinion, reveals a man fond of war. When he may enjoy peace without dishonour or harm, he chooses war; when he may live in idleness, he prefers toil, provided it be the toil of war; when he may keep his money without risk, he elects to diminish it by carrying on war. As for Clearchus, just as one spends upon a loved one or upon any other pleasure, so he wanted to spend upon war.”
ταῦτα οὖν φιλοπολέμου μοι δοκεῖ ἀνδρὸς ἔργα εἶναι, ὅστις ἐξὸν μὲν εἰρήνην ἄγειν ἄνευ αἰσχύνης καὶ βλάβης αἱρεῖται πολεμεῖν, ἐξὸν δὲ ῥᾳθυμεῖν βούλεται πονεῖν ὥστε πολεμεῖν, ἐξὸν δὲ χρήματα ἔχειν ἀκινδύνως αἱρεῖται πολεμῶν μείονα ταῦτα ποιεῖν: ἐκεῖνος δὲ ὥσπερ εἰς παιδικὰ ἢ εἰς ἄλλην τινὰ ἡδονὴν ἤθελε δαπανᾶν εἰς πόλεμον.
