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.
An 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.
The prince must consider, as has been in part said before, how to avoid those things which will make him hated or contemptible; and as often as he shall have succeeded he will have fulfilled his part, and he need not fear any danger in other reproaches.
A prince, therefore, must not mind incurring the charge of cruelty for the purpose of keeping his subjects united and confident; for, with a very few examples, he will be more merciful than those who, from excess of tenderness, allow disorders to arise, from whence spring murders and rapine; for these as a rule injure the whole community, while the executions carried out by the prince injure only one individual. And of all princes, it is impossible for a new prince to escape the name of cruel, new states being always full of dangers.
Severities should be dealt out all at once, so that their suddenness may give less offense; benefits ought to be handed ought drop by drop, so that they may be relished the more.
