The penal statutes form a very small proportion of the sixty-two books of the _Code_ and _Pandects_; and in all judicial proceeding the life or death of a citizen is determined with less caution or delay than the most ordinary question of covenant or inheritance. This singular distinction, though something may be allowed for the urgent necessity of defending the peace of society, is derived from the nature of criminal and civil jurisprudence. Our duties to the state are simple and uniform: the law by which he is condemned is inscribed not only on brass or marble, but on the conscience of the offender, and his guilt is commonly proved by the testimony of a single fact. But our relations to each other are various and infinite; our obligations are created, annulled, and modified by injuries, benefits, and promises; and the interpretation of voluntary contracts and testaments, which are often dictated by fraud or ignorance, affords a long and laborious exercise to the sagacity of the judge. The business of life is multiplied by the extent of commerce and dominion, and the residence of the parties in the distant provinces of an empire is productive of doubt, delay, and inevitable appeals from the local to the supreme magistrate. Justinian, the Greek emperor of Constantinople and the East, was the legal successor of the Latian shepherd who had planted a colony on the banks of the Tiber. In a period of thirteen hundred years the laws had reluctantly followed the changes of government and manners, and the laudable desire of conciliating ancient names with recent institutions destroyed the harmony and swelled the magnitude of the obscure and irregular system.
