Evils of this description ought not to be regarded as imaginary. One of the weak sides of republics, among their numerous advantages, is that they afford too easy an inlet to foreign corruption. An hereditary monarch, though often disposed to sacrifice his subjects to his ambition, has so great a personal interest in the government and in the external glory of the nation, that it is not easy for a foreign power to give him an equivalent for what he would sacrifice by treachery to the state. The world has accordingly been witness to few examples of this species of royal prostitution, though there have been abundant specimens of every other kind.
In republics, persons elevated from the mass of the community, by the suffrages of their fellow-citizens, to stations of great preeminence and power, may find compensations for betraying their trust, which, to any but minds animated and guided by superior virtue, may appear to exceed the proportion of interest they have in the common stock, and to overbalance the obligations of duty. Hence it is that history furnishes us with so many mortifying examples of the prevalency of foreign corruption in republican governments. How much this contributed to the ruin of the ancient commonwealths has been already delineated. It is well known that the deputies of the United Provinces have, in various instances, been purchased by the emissaries of the neighboring kingdoms. The Earl of Chesterfield (if my memory serves me right), in a letter to his court, intimates that his success in an important negotiation must depend on his obtaining a major’s commission for one of those deputies. And in Sweden the parties were alternately bought by France and England in so barefaced and notorious a manner that it excited universal disgust in the nation, and was a principal cause that the most limited monarch in Europe, in a single day, without tumult, violence, or opposition, became one of the most absolute and uncontrolled.
