of twenty-five that the terms "majority" and "minority" are employed in Roman law. _Pupilage_ or _wardship_ in modern jurisprudence had adjusted itself with tolerable regularity to the simple principle of protection to the immaturity of youth both bodily and mental. It has its natural termination with years of discretion. But for protection against physical weakness and for protection against intellectual incapacity, the Romans looked to two different institutions, distinct both in theory and design. The ideas attendant on both are combined in the modern idea of guardianship. The Law of Persons contains but one other chapter which can be usefully cited for our present purpose. The legal rules by which systems of nature jurisprudence regulate the connection of _Master and Slave_, present no very distinct traces of the original condition common to ancient societies. But there are reasons for this exception. There seems to be something in the institution of Slavery which has at all times either shocked or perplexed mankind, however little habituated to reflection, and however slightly advanced in the cultivation of its moral instincts. The compunction which ancient communities almost unconsciously experienced appears to have always resulted in the adoption of some imaginary principle upon which a defence, or at least a rationale, of slavery could be plausibly founded. Very early in their history the Greeks explained the institution as grounded on the intellectual inferiority of certain races and their consequent natural aptitude for the servile condition. The Romans, in a spirit equally characteristic, derived it from a supposed agreement between the victor and the vanquished in which the first stipulated for the perpetual services of his foe; and the other gained in consideration the life which he had legitimately forfeited. Such theories were not only unsound but plainly unequal to the case for which they affected to account. Still they exercised powerful influence in many ways. They satisfied the conscience of the Master. They perpetuated and probably increased the debasement of the Slave. And they naturally tended to put out of sight the relation in which servitude had originally stood to the rest of the domestic system. The relation, though not clearly exhibited, is casually indicated in many parts of primitive law, and more particularly in the typical system--that of ancient Rome.
