It is clear, then, that wisdom is knowledge having to do with certain principles and causes. But now, since it is this knowledge that we are seeking, we must consider the following point: of what kind of principles and of what kind of causes is wisdom the knowledge?
The true forms of government, therefore, are those in which the one, or the few, or the many, govern with a view to the common interest; but governments which rule with a view to the private interest, whether of the one or of the few, or of the many, are perversions. For the members of a state, if they are truly citizens, ought to participate in its advantages.
The soul is the cause or source of the living body. The terms cause and source have many senses. But the soul is the cause of its body alike in all three senses which we explicitly recognize. It is (a) the source or origin of movement, it is (b) the end, it is (c) the essence of the whole living body.
In the first place, then, men should guard against the beginning of change, and in the second place they should not rely upon the political devices of which I have already spoken invented only to deceive the people, for they are proved by experience to be useless.
If the poor, for example, because they are more in number, divide among themselves the property of the rich,- is not this unjust? . . this law of confiscation clearly cannot be just.
Nor was civil society founded merely to preserve the lives of its members; but that they might live well: for otherwise a state might be composed of slaves, or the animal creation... nor is it an alliance mutually to defend each other from injuries, or for a commercial intercourse. But whosoever endeavors to establish wholesome laws in a state, attends to the virtues and vices of each individual who composes it; from whence it is evident, that the first care of him who would found a city, truly deserving that name, and not nominally so, must be to have his citizens virtuous.
It is the mark of an educated mind to rest satisfied with the degree of precision which the nature of the subject admits and not to seek exactness where only an approximation is possible.
To let them share in the highest offices is to take a risk; inevitably, their unjust standards will cause them to commit injustice, and their lack of judgement will lead them into error. On the other hand there is a risk in not giving them a share, and in their non participation, for when there are many who have no property and no honours they inevitably constitute a huge hostile element in the state. But it can still remain open to them to participate in deliberating and judging.
Let us be well persuaded that everyone of us possesses happiness in proportion to his virtue and wisdom, and according as he acts in obedience to their suggestion.
