IT follows from what has gone before that the general will is always
right and tends to the public advantage; but it does not follow that the
deliberations of the people are always equally correct. Our will is
always for our own good, but we do not always see what that is; the
people is never corrupted, but it is often deceived, and on such
occasions only does it seem to will what is bad.
There is often a great deal of difference between the will of all and
the general will; the latter considers only the common interest, while
the former takes private interest into account, and is no more than a
sum of particular wills: but take away from these same wills the pluses
and minuses that cancel one another,[7] and the general will remains as
the sum of the differences.
If, when the people, being furnished with adequate information, held its
deliberations, the citizens had no communication one with another, the
grand total of the small differences would always give the general will,
and the decision would always be good. But when factions arise, and
partial associations are formed at the expense of the great association,
the will of each of these associations becomes general in relation to
its members, while it remains particular in relation to the State: it
may then be said that there are no longer as many votes as there are
men, but only as many as there are associations. The differences become
less numerous and give a less general result. Lastly, when one of these
associations is so great as to prevail over all the rest, the result is
no longer a sum of small differences, but a single difference; in this
case there is no longer a general will, and the opinion which prevails
is purely particular.
It is therefore essential, if the general will is to be able to express
itself, that there should be no partial society within the State, and
that each citizen should think only his own thoughts:[8] which was
indeed the sublime and unique system established by the great Lycurgus.
But if there are partial societies, it is best to have as many as
possible and to prevent them from being unequal, as was done by Solon,
Numa and Servius. These precautions are the only ones that can guarantee
that the general will shall be always enlightened, and that the people
shall in no way deceive itself.
