5.1. 1. Idea of this Book.
That the laws of education should relate to the principle of each government
has been shown in the preceding book. Now the same may be said of those
which the legislator gives to the whole society. The relation of laws to this
principle strengthens the several springs of government; and this principle derives
thence, in its turn, a new degree of vigour. And thus it is in mechanics, that action
is always followed by reaction.
Our design is, to examine this relation in each government,
beginning with the republican state, the principle of which is virtue.
