“For there is but one essential justice which cements society, and one law which establishes this justice. This law is right reason, which is the true rule of all commandments and prohibitions.”
Est enim unum ius quo deuincta est hominum societas et quod lex constituit una, quae lex est recta ratio imperandi atque prohibendi. Quam qui ignorat, is est iniustus, siue est illa scripta uspiam siue nusquam.
Book I, section 42; Translation by C.D. Yonge)
