But if this way of measuring happiness, when applied to private men, be ruinous and false, it is so no less when applied to nations. Wealth, commerce, extent of territory, and the knowledge of arts, are, when properly employed, the means of preservation, and the foundations of power. If they fail in part, the nation is weakened; if they were entirely with-held, the race would perish: their tendency is to maintain numbers of men, but not to constitute happiness. They will accordingly maintain the wretched, as well as the happy. They answer one purpose, but are not therefore sufficient for all; and are of little significance, when only employed to maintain a timid, dejected, and servile people.
Great and powerful states are able to overcome and subdue the weak; polished and commercial nations have more wealth, and practise a greater variety of arts, than the rude: but the happiness of men, in all cases alike, consists in the blessings of a candid, an active, and strenuous mind. And if we consider the state of society merely as that into which mankind are led by their propensities, as a state to be valued from its effect in preserving the species, in ripening their talents, and exciting their virtues, we need not enlarge our communities, in order to enjoy these advantages. We frequently obtain them in the most remarkable degree, where nations remain independent, and are of a small extent.
To increase the numbers of mankind, may be admitted as a great and important object: but to extend the limits of any particular state, is not, perhaps, the way to obtain it; while we desire that our fellow-creatures should multiply, it does not follow, that the whole should, if possible, be united under one head. We are apt to admire the empire of the Romans, as a model of national greatness and splendour: but the greatness we admire in this case, was ruinous to the virtue and the happiness of mankind; it was found to be inconsistent with all the advantages which that conquering people had formerly enjoyed in the articles of government and manners.
The emulation of nations proceeds from their division. Acluster of states, like a company of men, find the exercise of their reason, and the test of their virtues, in the affairs they transact, upon a foot of equality, and of separate interest. The measures taken for safety, including great part of the national policy, are relative in every state to what is apprehended from abroad. Athens was necessary to Sparta, in the exercise of her virtue, as steel is to flint in the production of fire; and if the cities of Greece had been united under one head, we should never have heard of Epaminondas or Thrasybulus, of Lycurgus or Solon.
When we reason in behalf of our species, therefore, although we may lament the abuses which sometimes arise from independence, and opposition of interest; yet, whilst any degrees of virtue remain with mankind, we cannot wish to croud, under one establishment, numbers of men who may serve to constitute several; or to commit affairs to the conduct of one senate, one legislative or executive power, which, upon a distinct and separate footing, might furnish an exercise of ability, and a theatre of glory, to many.
This may be a subject upon which no determinate rule can be given, but the admiration of boundless dominion is a ruinous error; and in no instance, perhaps, is the real interest of mankind more entirely mistaken.
The measure of enlargement to be wished for any particular state, is often to be taken from the condition of its neighbours.
Where a number of states are contiguous, they should be near an equality, in order that they may be mutually objects of respect and consideration, and in order that they may possess that independence in which the political life of a nation consists.
When the kingdoms of Spain were united, when the great fiefs in France were annexed to the crown, it was no longer expedient for the nations of Great Britain to continue disjoined.
The small republics of Greece, indeed, by their subdivisions, and the balance of their power, found almost in every village the object of nations. Every little district was a nursery of excellent men, and what is now the wretched corner of a great empire, was the field on which mankind have reaped their principal honours. But in modern Europe, republics of a similar extent, are like shrubs, under the shade of a taller wood, choked by the neighbourhood of more powerful states. In their case, a certain disproportion of force frustrates, in a great measure, the advantage of separation. They are like the trader in Poland, who is the more despicable, and the less secure, that he is neither master nor slave.
Independent communities, in the mean time, however weak, are averse to a coalition, not only where it comes with an air of imposition, or unequal treaty, but even where it implies no more than the admission of new members to an equal share of consideration with the old. The citizen has no interest in the annexation of kingdoms; he must find his importance diminished, as the state is enlarged: but ambitious men, under the enlargement of territory, find a more plentiful harvest of power, and of wealth, while government itself is an easier task. Hence the ruinous progress of empire; and hence free nations, under the shew of acquiring dominion, suffer themselves, in the end, to be yoked with the slaves they had conquered.
Our desire to augment the force of a nation is the only pretext for enlarging its territory; but this measure, when pursued to extremes, seldom fails to frustrate itself.
