The governments which have been remarkable in history for sustained mental ability and vigor in the conduct of affairs have generally been aristocracies. But they have been, without any exception, aristocracies of public functionaries. The ruling bodies have been so narrow, that each member, or at least each influential member of the body, was able to make, and did make, public business an active profession, and the principal occupation of his life. The only aristocracies which have manifested high governing capacities, and acted on steady maxims of policy through many generations, are those of Rome and Venice. But, at Venice, though the privileged order was numerous, the actual management of affairs was rigidly concentrated in a small oligarchy within the oligarchy, whose whole lives were devoted to the study and conduct of the affairs of the state. The Roman government partook more of the character of an open aristocracy like our own. But the really governing body, the Senate, was in exclusively composed of persons who had exercised public functions, and had either already filled, or were looking forward to fill the highest offices of the state, at the peril of a severe responsibility in case of incapacity and failure. When once members of the Senate, their lives were pledged to the conduct of public affairs; they were not permitted even to leave Italy except in the discharge of some public trust; and unless turned out of the Senate by the censors for character or conduct deemed disgraceful, they retained their powers and responsibilities to the end of life. In an aristocracy thus constituted, every member felt his personal importance entirely bound up with the dignity and estimation of the commonwealth which he administered, and with the part he was able to play in its councils. This dignity and estimation were quite different things from the prosperity or happiness of the general body of the citizens, and were often wholly incompatible with it. But they were closely linked with the external success and aggrandisement of the state; and it was, consequently, in the pursuit of that object almost exclusively, that either the Roman or the Venetian aristocracies manifested the systematically wise collective policy and the great individual capacities for government for which history has deservedly given them credit.
