The end Lycurgus proposed was the public happiness: convinced that the happiness of a city, like that of a private person, depends upon virtue, and upon being well within himself. He regulated Lacedæmon so as it might always suffice to its own happiness, and act upon principles of wisdom and equity. From thence arose that universal esteem of the neighbouring people, and even of strangers, for the Lacedæmonians, who asked them neither money, ships, nor troops; but only that they should lend them a Lacedæmonian to command their armies; and when they had obtained their request, they paid him certain obedience, with every kind of honour and respect. There were a multitude of other regulations, some of which were, doubtless, of a very imperfect tendency; but it is certain that the declension of Sparta began with the violation of Lycurgus's laws. No sooner had the ambition of reigning over all Greece inspired them with the design of having naval armies and foreign troops, and that money was necessary for the support of those forces, than Lacedæmon, forgetting her ancient maxims, saw herself reduced to have recourse to the Barbarians, which, till then, she had detested, and basely to betray her court to the kings of Persia, whom she had formerly vanquished with so much glory; and that only to draw from them some aids of money and troops against their own brethren; that is to say, against people born and settled in Greece, like themselves. Thus had they the imprudence and misfortune to recal, with gold and silver, all the vices and crimes which the iron money had banished; and to prepare the way to the changes which ensued, and were the causes of their ruin. And this infinitely exalts the wisdom of Lycurgus, in having foreseen at such a distance what might strike at the happiness of his citizens, and provided salutary remedies against it in the form of government he established at Lacedæmon.
