...people are by nature fickle, and it is easy to persuade them of something, but difficult to keep them persuaded.
Niccolo MachiavelliThere is nothing so difficult or so dangerous as to undertake to change the order of things.
Niccolo MachiavelliI hold it to be a proof of great prudence for men to abstain from threats and insulting words toward anyone, for neither diminishes the strength of the enemy.
Niccolo MachiavelliAn armed republic submits less easily to the rule of one of its citizens than a republic armed by foreign forces. Rome and Sparta were for many centuries well armed and free. The Swiss are well armed and enjoy great freedom. Among other evils caused by being disarmed, it renders you contemptible. It is not reasonable to suppose that one who is armed will obey willingly one who is unarmed; or that any unarmed man will remain safe among armed servants.
Niccolo MachiavelliIt 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.
Niccolo MachiavelliAnd 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.
