There is nothing so difficult or so dangerous as to undertake to change the order of things.
Niccolo MachiavelliHe who blinded by ambition, raises himself to a position whence he cannot mount higher, must thereafter fall with the greatest loss.
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.
