[H]ere we bless your simplicity but do not envy your folly. — Thucydides

"The real cause I consider to be the one which was formerly most kept out of sight. The growth of the power of Athens, and the alarm which this inspired the Lacedaemon, made war inevitable."

"Ἀμαθία μὲν θράσος, λογισμὸς δὲ ὄκνον φέρει"

"When men are once checked in what they consider their special excellence, their whole opinion of themselves suffers more than if they had not at first believed in their superiority, the unexpected shock to their pride causing them to give way more than their real strength warrants; and that is probably now the case with the Athenians."

"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."

"That war is an evil is a proposition so familiar to every one that it would be tedious to develop it. No one is forced to engage in it by ignorance, or kept out of it by fear, if he fancies there is anything to be gained by it."

"They stood where they stood by the power of the sword."
