“The particular aspect of history which both attracts and benefits its readers is the examination of causes and the capacity, which is the reward of this study, to decide in each case the best policy to follow. Now in all political situations we must understand that the principle factor which makes for success or failure is the form of a state's constitution: it is from this source, as if from a fountainhead, that all designs and plans of action not only originate but reach their fulfillment.”

“From this I conclude that the best education for the situations of actual life consists of the experience we acquire from the study of serious history. For it is history alone which without causing us harm enables us to judge what is the best course in any situation or circumstance.”

“If history is deprived of the Truth, we are left with nothing but an idle, unprofitable tale.”

“In our own time the whole of Greece has been subject to a low birth rate and a general decrease of the population, owing to which cities have become deserted and the land has ceased to yield fruit, although there have neither been continuous wars nor epidemics...For as men had fallen into such a state of pretentiousness, avarice, and indolence that they did not wish to marry, or if they married to rear the children born to them, or at most as a rule but one or two of them, so as to leave these in affluence and bring them up to waste their substance, the evil rapidly and insensibly grew.”

“At the sight of the city utterly perishing amidst the flames Scipio burst into tears, and stood long reflecting on the inevitable change which awaits cities, nations, and dynasties, one and all, as it does every one of us men. This, he thought, had befallen Ilium, once a powerful city, and the once mighty empires of the Assyrians, Medes, Persians, and that of Macedonia lately so splendid. And unintentionally or purposely he quoted---the words perhaps escaping him unconsciously---"The day shall be when holy Troy shall fallAnd Priam, lord of spears, and Priam's folk."And on my asking him boldly (for I had been his tutor) what he meant by these words, he did not name Rome distinctly, but was evidently fearing for her, from this sight of the mutability of human affairs. . . . Another still more remarkable saying of his I may record. . . [When he had given the order for firing the town] he immediately turned round and grasped me by the hand and said: "O Polybius, it is a grand thing, but, I know not how, I feel a terror and dread, lest some one should one day give the same order about my own native city.”

“The state should confine itself to establishing rules applying to general types of situations and should allow the individuals freedom in everything which depends on the circumstances of time and place, because only the individuals concerned in each instance can fully know these circumstances and adapt their actions to them. If the individuals are able to use their knowledge effectively in making plans, they must be able to predict actions of the state which may affect these plans. But if the actions of the state are to be predictable, they must be determined by rules fixed independently of the concrete circumstances which can be neither foreseen nor taken into account beforehand; and the particular effects of such actions will be unpredictable. If, on the other hand, the state were to direct the individual’s actions so as the achieve particular ends, its actions would have to be decided on the basis of the full circumstances of the moment and would therefore be unpredictable. Hence the familiar fact that the more the state “plans”, the more difficult planning becomes for the individual.”

“There are illusions of popular history which a successful religion must promote: Evil men never prosper; only the brave deserve the fair; honesty is the best policy; actions speak louder than words; virtue always triumphs; a good deed is its own reward; any bad human can be reformed; religious talismans protect one from demon possession; only females understand the ancient mysteries; the rich are doomed to unhappiness.”
