A democratic republic cannot be permanently maintained in any country, unless there prevail amongst the people much public spirit and intelligence; and even if it be maintained, civic virtues of the highest kind are required to prevent the existence of evils incidental to the abuse of power. In the republics of ancient Greece, oppression was practised by the dominant majority of the multitude, with as much recklessness as has ever been exhibited by the caprice of imperial tyranny. The republic of Rome was never free from faction.
These observations are made, not for the purpose of reconciling the reader to the maintenance of tyranny in any form; not for the purpose of deterring him from seeking the greatest possible perfectibility in political institutions; but in order to prevent him from being misled by mere names, and in order to convince him that much of evil must be expected under even the most perfect form of government that can be devised.”
