It is a course which perhaps would not have been necessary had it been possible to form a state composed of wise men, but as every multitude is fickl… - Polybius

How highly should we honor the Macedonians, who for the greater part of their lives never cease from fighting with the barbarians for the sake of the security of Greece? For who is not aware that Greece would have constantly stood in the greater danger, had we not been fenced by the Macedonians and the honorable ambition of their kings?

I observe that while several modern writers deal with particular wars and certain matters connected with them, no one, as far as I am aware, has even attempted to inquire critically when and whence the general and comprehensive scheme of events originated and how it led up to the end. I therefore thought it quite necessary not to leave unnoticed or allow to pass into oblivion this the finest and most beneficent of the performances of Fortune. For though she is ever producing something new and ever playing a part in the lives of men, she has not in a single instance ever accomplished such a work, ever achieved such a triumph, as in our own times. We can no more hope to perceive this from histories dealing with particular events than to get at once a notion of the form of the whole world, its disposition and order, by visiting, each in turn, the most famous cities, or indeed by looking at separate plans of each: a result by no means likely. He indeed who believes that by studying isolated histories he can acquire a fairly just view of history as a whole, is, as it seems to me, much in the case of one, who, after having looked at the dissevered limbs of an animal once alive and beautiful, fancies he has been as good as an eyewitness of the creature itself in all its action and grace.

The date from which I propose to begin my history is the 140th Olympiad [220 - 216 B.C.], and the events are the following: (1) in Greece the so‑called Social War, the first waged against the Aetolians by the Achaeans in league with and under the leadership of Philip of Macedon, the son of Demetrius and father of Perseus, (2) in Asia the war for Coele-Syria between Antiochus and Ptolemy Philopator, (3) in Italy, Libya, and the adjacent regions, the war between Rome and Carthage, usually known as the Hannibalic War. These events immediately succeed those related at the end of the work of Aratus of Sicyon. Previously the doings of the world had been, so to say, dispersed, as they were held together by no unity of initiative, results, or locality; but ever since this date history has been an organic whole, and the affairs of Italy and Libya have been interlinked with those of Greece and Asia, all leading up to one end. And this is my reason for beginning their systematic history from that date.
