We Greeks believe that a man who takes no part in public affairs is not merely lazy, but good for nothing
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.
ThucydidesIt is a common mistake in going to war to begin at the wrong end, to act first, and wait for disasters to discuss the matter.
