Ἀμαθία μὲν θράσος, λογισμὸς δὲ ὄκνον φέρει — Thucydides

"Let him remember that many before now have tried to chastise a wrongdoer, and failing to punish their enemy have not even saved themselves; while many who have trusted in force to gain an advantage, instead of gaining anything more, have been doomed to lose what they had. Vengeance is not necessarily successful because wrong has been done, or strength sure because it is confident; but the incalculable element in the future exercises the widest influence, and is the most treacherous, and yet in fact the most useful of all things, as it frightens us all equally, and thus makes us consider before attacking each other."

"Thus they toil on in trouble and danger all the days of their life, with little opportunity for enjoying, being ever engaged in getting: their only idea of a holiday is to do what the occasion demands, and to them laborious occupation is less of a misfortune than the peace of a quiet life. To describe their character in a word, one might truly say that they were born into the world to take no rest themselves and to give none to others."

"Again, in our enterprises we present the singular spectacle of daring and deliberation, each carried to its highest point, and both united in the same persons; although usually decision is the fruit of ignorance, hesitation of reflection. But the palm of courage will surely be adjudged most justly to those, who best know the difference between hardship and pleasure and yet are never tempted to shrink from danger. In generosity we are equally singular, acquiring our friends by conferring, not by receiving, favours."

"They have discovered that the length of time we have now been in commission has rotted our ships and wasted our crews, and that with the completeness of our crews and the soundness of the pristine efficiency of our navy has departed. For it is impossible for us to haul our ships ashore and dry them out because the enemys vessels being as many or more than our own, we are constantly anticipating an attack."

"The fate of those of their neighbours who had already rebelled and had been subdued was no lesson to them; their own prosperity could not dissuade them from affronting danger; but blindly confident in the future, and full of hopes beyond their power though not beyond their ambition, they declared war and made their decision to prefer might to right, their attack being determined not by provocation but by the moment which seemed propitious. The truth is that great good fortune coming suddenly and unexpectedly tends to make a people insolent; in most cases it is safer for mankind to have success in reason than out of reason; and it is easier for them, one may say, to stave off adversity than to preserve prosperity."

"I could have wished that the reputations of many brave men were not to be imperilled in the mouth of a single individual, to stand or fall according as he spoke well or ill. For it is hard to speak properly upon a subject where it is even difficult to convince your hearers that you are speaking the truth. On the one hand, the friend who is familiar with every fact of the story may think that some point has not been set forth with that fullness which he wishes and knows it to deserve; on the other, he who is a stranger to the matter may be led by envy to suspect exaggeration if he hears anything above his own nature. For men can endure to hear others praised only so long as they can severally persuade themselves of their own ability to equal the actions recounted: when this point is passed, envy comes in and with it incredulity."
