Abstinence from all injustice to other first-rate powers is a greater tower of strength than anything that can be gained by the sacrifice of permanent tranquillity for an apparent temporary advantage.
ThucydidesIn peace and prosperity states and individuals have better sentiments, because they do not find themselves suddenly confronted with imperious necessities; but war takes away the easy supply of daily wants and so proves a rough master that brings most men's characters to a level with their fortunes
ThucydidesIndeed men too often take upon themselves in the prosecution of their revenge to set the example of doing away with those general laws to which all can look for salvation in adversity, instead of allowing them to subsist against the day of danger when their aid may be required
ThucydidesFor if many ill-conceived plans have succeeded through the still greater lack of judgment of an opponent, many more, apparently well laid, have on the contrary ended in disgrace. The confidence with which we form our schemes is never completely justified in their execution; speculation is carried on in safety, but, when it comes to action, fear causes failure.
