Thucydides 6.9.1 (Nicias speaking; tr. Charles Forster Smith):
To me, however, it seems that we ought to consider yet again this very question, whether it is best to send the ships at all, and that we ought not, on such slight deliberation about matters of great importance, at the instigation of men of alien race, to undertake a war that does not concern us.
ἐμοὶ μέντοι δοκεῖ καὶ περὶ αὐτοῦ τούτου ἔτι χρῆναι σκέψασθαι, εἰ ἄμεινόν ἐστιν ἐκπέμπειν τὰς ναῦς, καὶ μὴ οὕτω βραχείᾳ βουλῇ περὶ μεγάλων πραγμάτων ἀνδράσιν ἀλλοφύλοις πειθομένους πόλεμον οὐ προσήκοντα ἄρασθαι.
