The jurisprudence which had been grossly adapted to the wants of the first Romans, was polished and improved in the seventh century of the city, by the alliance of Grecian philosophy. The ScÊvolas had been taught by use and experience; but Servius Sulpicius was the first civilian who established his art on a certain and general theory. For the discernment of truth and falsehood he applied, as an infallible rule, the logic of Aristotle and the stoics, reduced particular cases to general principles, and diffused over the shapeless mass the light of order and eloquence. Cicero, his contemporary and friend, declined the reputation of a professed lawyer; but the jurisprudence of his country was adorned by his incomparable genius, which converts into gold every object that it touches. After the example of Plato, he composed a republic; and, for the use of his republic, a treatise of laws; in which he labors to deduce from a celestial origin the wisdom and justice of the Roman constitution. The whole universe, according to his sublime hypothesis, forms one immense commonwealth: gods and men, who participate of the same essence, are members of the same community; reason prescribes the law of nature and nations; and all positive institutions, however modified by accident or custom, are drawn from the rule of right, which the Deity has inscribed on every virtuous mind. From these philosophical mysteries, he mildly excludes the sceptics who refuse to believe, and the epicureans who are unwilling to act. The latter disdain the care of the republic: he advises them to slumber in their shady gardens. But he humbly entreats that the new academy would be silent, since her bold objections would too soon destroy the fair and well ordered structure of his lofty system. Plato, Aristotle, and Zeno, he represents as the only teachers who arm and instruct a citizen for the duties of social life. Of these, the armor of the stoics was found to be of the firmest temper; and it was chiefly worn, both for use and ornament, in the schools of jurisprudence. From the portico, the Roman civilians learned to live, to reason, and to die: but they imbibed in some degree the prejudices of the sect; the love of paradox, the pertinacious habits of dispute, and a minute attachment to words and verbal distinctions. The superiority of _form_ to _matter_ was introduced to ascertain the right of property: and the equality of crimes is countenanced by an opinion of Trebatius, that he who touches the ear, touches the whole body; and that he who steals from a heap of corn, or a hogshead of wine, is guilty of the entire theft.
