Therefore, a prudent ruler ought not to keep faith when by so doing it would be against his interest, and when the reasons which made him bind himself no longer exist. If men were all good, this precept would not be a good one; but as they are bad, and would not observe their faith with you, so you are not bound to keep faith with them.
When evening comes, I return home and go into my study. On the threshold I strip off my muddy, sweaty clothes of everyday, and put on the robes of court and palace, and in this graver dress I enter the antique courts of the ancients and am welcomed by them, and there I taste the food that alone is mine, and for which I was born. And there I make bold to speak to them and ask the motives of their actions, and they, in their humanity, reply to me. And for the space of four hours I forget the world, remember no vexation, fear poverty no more, tremble no more at death; I pass indeed into their world.
I desire to go to Hell and not to Heaven. In the former I shall enjoy the company of popes, kings and princes, while in the latter are only beggars, monks and apostles
And what physicians say about disease is applicable here: that at the beginning a disease is easy to cure but difficult to diagnose; but as time passes, not having been recognized or treated at the outset, it becomes easy to diagnose but difficult to cure. The same thing occurs in affairs of state; for by recognizing from afar the diseases that are spreading in the state (which is a gift given only to the prudent ruler), they can be cured quickly; but when, not having been recognized, they are not recognized and are left to grow to the extent that everyone recognizes them, there is no longer any cure.
There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.

as the physicians say it happens in hectic fever, that in the beginning of the malady it is easy to cure but difficult to detect, but in the course of time, not having been either detected or treated in the beginning, it becomes easy to detect but difficult to cure
As all those have shown who have discussed civil institutions, and as every history is full of examples, it is necessary to whoever arranges to found a Republic and establish laws in it, to presuppose that all men are bad and that they will use their malignity of mind every time they have the opportunity.
It is the duty of a man of honor to teach others the good which he has not been able to do himself because of the malignity of the times, that this good finally can be done by another more loved in heaven.
There is simply no comparison between a man who is armed and one who is not. It is simply unreasonable to expect that an armed man should obey one who is unarmed, or that an unarmed man should remain safe and secure when his servants are armed.
That prince is highly esteemed who conveys this impression of himself, and he who is highly esteemed is not easily conspired against; for, provided it is well known that he is an excellent man and revered by his people, he can only be attacked with difficulty.
