There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless.
Men seldom rise from low condition to high rank without employing either force or fraud, unless that rank should be attained either by gift or inheritance.
War should be the only study of a prince. He should consider peace only as a breathing-time, which gives him leisure to contrive, and furnishes as ability to execute, military plans.
Men are of three different capacities: one understands intuitively; another understands so far as it is explained; and a third understands neither of himself nor by explanation. The first is excellent, the second, commendable, and the third, altogether useless.
For it must be noted, that men must either be caressed or else annihilated; they will revenge themselves for small injuries, but cannot do so for great ones; the injury therefore that we do to a man must be such that we need not fear his vengeance.
You do not know the unfathomable cowardice of humanity...servile in the face of force, pitiless in the face of weakness, implacable before blunders, indulgent before crimes...and patient to the point of martyrdom before all the violences of bold despotism.
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.
How we live is so different from how we ought to live that he who studies what ought to be done rather than what is done will learn the way to his downfall rather than to his preservation.
We must distinguish between those who depend on others, that is between those who to achieve their purposes can force the issue and those who must use persuasion. In the second case, they always come to grief, having achieved nothing; when, however, they depend on their own resources and can force the issue, then they are seldom endangered.
Therefore, in order not to have to rob his subjects, to be able to defend himself, not to become poor and contemptible, and not to be forced to become rapacious, a prince must consider it of little importance if he incurs the name of miser, for this is one of the vices that permits him to rule.
