Anyone who studies present and ancient affairs will easily see how in all cities and all peoples there still exist, and have always existed, the same desires and passions. Thus, it is an easy matter for him who carefully examines past events to foresee future events in a republic and to apply the remedies employed by the ancients, or, if old remedies cannot be found, to devise new ones based upon the similarity of the events. But since these matters are neglected or not understood by those who read, or, if understood, remain unknown to those who govern, the result is that the same problems always exist in every era.

The people resemble a wild beast, which, naturally fierce and accustomed to live in the woods, has been brought up, as it were, in a prison and in servitude, and having by accident got its liberty, not being accustomed to search for its food, and not knowing where to conceal itself, easily becomes the prey of the first who seeks to incarcerate it again.

I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.

So in all human affairs one notices, if one examines them closely, that it is impossible to remove one inconvenience without another emerging.

For as when much superfluous matter has gathered in simple bodies, nature makes repeated efforts to remove and purge it away, thereby promoting the health of these bodies, so likewise as regards that composite body the human race, when every province of the world so teems with inhabitants that they can neither subsist where they are nor remove elsewhere, every region being equally crowded and over-peopled, and when human craft and wickedness have reached their highest pitch, it must needs come about that the world will purge herself in one or another of these three ways, to the end that men, becoming few and contrite, may amend their lives and live with more convenience.

The demands of a free populace, too, are very seldom harmful to liberty, for they are due either to the populace being oppressed or to the suspicious that it is going to be oppressed... and, should these impressions be false, a remedy is provided in the public platform on which some man of standing can get up, appeal to the crowd, and show that it is mistaken. And though, as Tully remarks, the populace may be ignorant, it is capable of grasping the truth and readily yields when a man, worthy of confidence, lays the truth before it.

Men never do good unless necessity drives them to it; but when they are free to choose and can do just as they please, confusion and disorder become rampant.

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; and if such malignity is hidden for a time, it proceeds from the unknown reason that would not be known because the experience of the contrary had not been seen, but time, which is said to be the father of every truth, will cause it to be discovered.

A prince who is not wise himself will never take good advice.

The first method for estimating the intelligence of a ruler is to look at the men he has around him.
