4. Fourth Conclusion

91. Therefore, so that this law may be just, one must see how such positive law may be just.

92. Let the fourth conclusion be then that ‘a just positive law requires in the legislator prudence and authority’.

Prudence, so that the legislator command according to practical right reason what must be established for the community.

Authority, because ‘lex’ (law) comes from ‘ligando’ (‘binding’), but no sentence at all of a prudent man binds the community, or anyone, if there is no one presiding.
