Polybios Histories 9.37
"Let it, however, be granted that what I have now said may in the eyes of severe critics be regarded as beside the subject. I will now return to the main point at issue, as they state it. It was this: 'If the circumstances are the same now as at the time when you made alliance with the Aetolians, then your policy ought to remain on the same lines.' That was their first proposition. 'But if they have been entirely changed, then it is fair that you should now deliberate on the demands made to you as on a matter entirely new and unprejudiced.' I ask you therefore, Cleonicus and Chlaeneas, who were your allies on the former occasion when you invited this people to join you? Were they not all the Greeks? But with whom are you now united, or to what kind of federation are you now inviting this people? Is it not to one with the foreigner? A mighty similarity exists, no doubt, in your minds, and no diversity at all! Then you were contending for glory and supremacy with Achaeans and Macedonians, men of kindred blood with yourselves, and with Philip their leader;
now a war of slavery is threatening Greece against men of another race, whom you think to bring against Philip, but have really unconsciously brought against yourselves and all Greece. For just as men in the stress of war, by introducing into their cities garrisons superior in strength to their own forces, while successfully repelling all danger from the enemy, put themselves at the mercy of their friends,—just so are the Aetolians acting in the present case. For in their desire to conquer Philip and humble Macedonia, they have unconsciously brought such a mighty cloud from the west, as for the present perhaps will overshadow Macedonia first, but which in the sequel will be the origin of heavy evils to all Greece.
Οὐ μὴν ἀλλ᾽ εἰρήσθω μέν μοι ταῦτα, κρινέσθω δὲ παρὰ τοῖς φιλοτιμότερον διακειμένοις ἐκτὸς εἶναι τῶν ἐνεστώτων. ἐπὶ δὲ τὸ συνέχον, ὡς οὗτοί φασιν, ἐπάνιμεν.  τοῦτο δ᾽ ἦν, εἰ μὲν ὡμοίωται τὰ πράγματα νῦν καὶ καθ᾽ οὓς καιροὺς ἐποιεῖσθε τὴν πρὸς τούτους συμμαχίαν, διότι δεῖ μένειν καὶ τὴν ὑμετέραν αἵρεσιν ἐπὶ τῶν ὑποκειμένων: ταῦτα γὰρ ἐν ἀρχαῖς εἶναι:  εἰ δ᾽ ὁλοσχερῶς ἠλλοίωται, διότι δίκαιόν ἐστι καὶ νῦν ὑμᾶς ἐξ ἀκεραίου βουλεύεσθαι περὶ τῶν παρακελευομένων.  ἐρωτῶ τοιγαροῦν ὑμᾶς, ὦ Κλεόνικε καὶ Χλαινέα, τίνας ἔχοντες συμμάχους τότε παρεκαλεῖτε τούτους εἰς τὴν κοινοπραγίαν; ἆρ᾽ οὐ πάντας Ἕλληνας;  τίσι δὲ νῦν κοινωνεῖτε τῶν ἐλπίδων, ἢ πρὸς ποίαν παρακαλεῖτε τούτους συμμαχίαν;  ἆρ᾽ οὐ πρὸς τὴν τῶν βαρβάρων; ὅμοιά γε δοκεῖ τὰ πράγμαθ᾽ ὑμῖν ὑπάρχειν νῦν καὶ πρότερον, ἀλλ᾽ οὐ τἀναντία:  τότε μὲν γὰρ ὑπὲρ ἡγεμονίας καὶ δόξης ἐφιλοτιμεῖσθε πρὸς Ἀχαιοὺς καὶ Μακεδόνας ὁμοφύλους καὶ τὸν τούτων ἡγεμόνα Φίλιππον
: νῦν δὲ περὶ δουλείας ἐνίσταται πόλεμος τοῖς Ἕλλησι πρὸς ἀλλοφύλους ἀνθρώπους,  οὓς ὑμεῖς δοκεῖτε μὲν ἐπισπᾶσθαι κατὰ Φιλίππου, λελήθατε δὲ κατὰ σφῶν αὐτῶν ἐπεσπασμένοι καὶ κατὰ πάσης Ἑλλάδος.  ὥσπερ γὰρ οἱ κατὰ τὰς πολεμικὰς περιστάσεις βαρυτέρας ἐπαγόμενοι φυλακὰς εἰς τὰς πόλεις τῆς αὑτῶν δυνάμεως χάριν τῆς ἀσφαλείας ἅμα τὸν ἀπὸ τῶν ἐχθρῶν ἀπωθοῦνται φόβον καὶ ποιοῦσιν ὑποχειρίους σφᾶς αὐτοὺς ταῖς τῶν φίλων ἐξουσίαις, τὸν αὐτὸν τρόπον καὶ νῦν Αἰτωλοὶ διανοοῦνται.  βουλόμενοι γὰρ περιγενέσθαι Φιλίππου καὶ ταπεινῶσαι Μακεδόνας, λελήθασιν αὑτοῖς ἐπισπασάμενοι τηλικοῦτο νέφος ἀπὸ τῆς ἑσπέρας, ὃ κατὰ μὲν τὸ παρὸν ἴσως πρώτοις ἐπισκοτήσει Μακεδόσι, κατὰ δὲ τὸ συνεχὲς πᾶσιν ἔσται τοῖς Ἕλλησι μεγάλων κακῶν αἴτιον.
