But in Republics there is a stronger vitality, a fiercer hatred, a keener thirst for revenge. The memory of their former freedom will not let them rest; so that the safest course is either to destroy them, or to go and live in them.
David Hume
Tis evident that all reasonings concerning matter of fact are founded on the relation of cause and effect, and that we can never infer the existence of one object from another, unless they be connected together, either mediately or immediately. . . Here is a billiard ball lying on the table, and another ball moving toward it with rapidity. They strike; and the ball which was formerly at rest now acquires a motion. This is as perfect an instance of the relation of cause and effect as any which we know, either by sensation or reflection.
