Those who have experienced good and bad luck many times have every reason to be skeptical of successes
ThucydidesIt is the habit of mankind to entrust to careless hope what they long for, and to use sovereign reason to thrust aside what they do not desire
ThucydidesSome legislators only wish to vengeance against a particular enemy. Others only look out for themselves. They devote very little time on the consideration of any public issue. They think that no harm will come from their neglect. They act as if it is always the business of somebody else to look after this or that. When this selfish notion is entertained by all, the commonwealth slowly begins to decay.
