But I may be answered, after all, though our age be not so virtuous, and though the large accumulation in wealth has in reality not made mankind happier; still, it cannot be denied, you are in a prosperous condition, and prosperity is a solid basis of your country’s future. Industry, navigation, commerce, have so much developed, they have formed so many ties by which every citizen is linked to his country’s fate, that your own material interest is a security to your country’s future.
In loving your own selves you love your country, and in loving your country you love your own selves. This community of public and private interest will make you avoid the stumbling-block over which others fell. Prosperity is, of course, a great benefit; it is one of the aims of human society; but when prosperity becomes too material, it does not always guarantee the future. Paradoxical as it may appear, too much prosperity is often dangerous, and some national misfortune is now and then a good preservative of prosperity. For great prosperity makes nations careless of their future; seeing no immediate danger, they believe no danger possible; and then when a danger comes, either by sudden chance or by the slow accumulation of noxious elements, then, frightened by the idea that in meeting the danger their private property might be injured or lost, selfishness often prevails over patriotism, and men become ready to submit to arrogant pretensions, and compromise with exigencies at the price of principles, and republics flatter despots, and freemen covet the friendship and indulgence of tyrants, only that things may go on just as they go, though millions weep and nations groan; but still, things should go on just as they go, because every change may claim a sacrifice, or affect our thriving private interest. Such is often the effect of too great, of too secure prosperity. Therefore, prosperity alone affords yet no security.
