49. To the recital of matters past, he subjoined, that “his intention was to depart shortly for Italy, and to carry with him all his troops; [2] that they should hear, within ten days, of the garrisons having evacuated Demetrias; and that Chalcis, the citadel of Corinth, should be before their own eyes evacuated to the Achaeans: [3] that all the world might know whose habit it was to deceive, that of the Romans or the Aetolians, who had spread insinuations, that the cause of liberty had been unwisely intrusted to the Romans, and that they had only received as [4??] their masters the Romans in exchange for the Macedonians. But they were men who never scrupled what they either said or did. [5] The rest of the nations he advised to form their estimate of friends from deeds, not from words; and to satisfy themselves whom they ought to trust, and [p. 1540]against whom they ought to be on their guard; [6] to use their liberty with moderation: for, when regulated by prudence, it was productive of happiness both to individuals and to states; [7] but, when pushed to excess, it became not only obnoxious to others, but to the possessors of it themselves an unbridled and headstrong impulse. [8] He recommended, that those at the head of affairs, and all the several ranks of men in each particular state, should cultivate harmony between themselves; and that all should direct their views to the general interest of the whole. [9] For, while they acted in concert, no king or tyrant would be sufficiently powerful against them: but discord and dissension gave every advantage to those who might plot against them; as the party worsted in a domestic dispute generally join themselves with foreigners, rather than submit to a countryman of their own. [10] He then exhorted them, as the arms of others had procured their liberty, and the good faith of foreigners had restored it to them, to apply now their own diligent care to the watching and guarding of it; [11] that the Roman people might perceive that those on whom they had bestowed liberty were deserving of it, and that their kindness had not been ill placed.”
