Prudent men are in the habit of saying — and not by chance or without basis — that he who wishes to see what is to come should observe what has already happened, because all the affairs of the world, in every age, have their individual counterparts in ancient times. The reason for this is that since they are carried on by men, who have and always have had the same passions, of necessity the same results appear.
Niccolò Machiavelli (1469-1527) Italian politician, philosopher, political scientist

Alt. trans.: "The wise are wont to say, and not without reason or at random, that he who would forecast what is about to happen should look to what has been; since all human events, whether present or to come, have their exact counterpart in the past. And this, because these events are brought about by men, whose passions and dispositions remaining in all ages the same naturally give rise to the same effects." [tr. Thomson]

Forecast: To observe that which has passed, and guess it will happen again; to anticipate the future by guessing at the past; to predict that an event will happen, if it does, by basing calculations on events that have already happened, if they did.
