Wise men say, and not without reason, that whosoever wished to foresee the future might consult the past.
Niccolo MachiavelliA wise ruler ought never to keep faith when by doing so it would be against his interests.
Niccolo MachiavelliIt is a true observation of ancient writers, that as men are apt to be cast down by adversity, so they, are easily satiated with prosperity, and that joy and grief produce the same effects. For whenever men are not obliged by necessity to fight they fight from ambition, which is so powerful a passion in the human breast that however high we reach we are never satisfied.
