_Injustice._--It is dangerous to tell the people that the laws are unjust; for they obey them only because they think them just. Therefore it is necessary to tell them at the same time that they must obey them because they are laws, just as they must obey superiors, not because they are just, but because they are superiors. In this way all sedition is prevented, if this can be made intelligible, and it be understood what is the proper definition of justice.
The world is a good judge of things, for it is in natural ignorance, which is man's true state.[124] The sciences have two extremes which meet. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great intellects, who, having run through all that men can know, find they know nothing, and come back again to that same ignorance from which they set out; but this is a learned ignorance which is conscious of itself. Those between the two, who have departed from natural ignorance and not been able to reach the other, have some smattering of this vain knowledge, and pretend to be wise. These trouble the world, and are bad judges of everything. The people and the wise constitute the world; these despise it, and are despised. They judge badly of everything, and the world judges rightly of them.
_The reason of effects._--Continual alternation of pro and con.
We have then shown that man is foolish, by the estimation he makes of things which are not essential; and all these opinions are destroyed. We have next shown that all these opinions are very sound, and that thus, since all these vanities are well founded, the people are not so foolish as is said. And so we have destroyed the opinion which destroyed that of the people.
But we must now destroy this last proposition, and show that it remains always true that the people are foolish, though their opinions are sound; because they do not perceive the truth where it is, and, as they place it where it is not, their opinions are always very false and very unsound.
_The reason of effects._--The weakness of man is the reason why so many things are considered fine, as to be good at playing the lute. It is only an evil because of our weakness.
