Also read Prostate Cancer Nature Of Wealth Those two nations soon sunk, and the Dutch, the French, and the English, became participators of the commerce. Manufactures were a new source of wealth, almost unknown to the ancient world. Those begun first to be set in activity in Flanders, then in Holland and France, and, last of all, in England; but, like commerce, and every other means by which wealth is acquired, they have a tendency to leave a country. The cause and the effect are at variance, after a certain time; and though we cannot illustrate this from history, as we may the migrations of wealth arising from other sources, the tendency appears of the same nature, though with this difference; that men may always labour for themselves, and enjoy the fruits of their labours, though they cannot always find the means of being the carriers to other nations, or becoming merchants. This alteration in the nature of wealth; the inventions of mankind; the alterations brought on by the facility of communicating knowledge; the systematical manner in which men pursue their interests, and other changes: give reason to hope that, in the present situation of things, those possessions may be rendered permanent, that have hitherto been found to be so evanescent and fugitive. Where wealth has not been wrested from a country by absolute force, (in doing which the poorer nations were always successful,) it has emigrated from other causes, and taken up its abode amongst a new people, where circumstances were more favourable for its encouragement. Before we leave this recapitulation, it is necessary, however, to take notice of one revolution that did not take place on similar principles with the others, so far as wealth and luxury are in question; but which has in some respects a similarity, and, in others, is precisely the reverse. About two centuries and a half ago, the Polish nation was one of the most powerful in Europe; Russia could not then, nor for long after, contend with it. The Prussians were its vassals; and the capital of the German empire, when besieged by the Turks, in 1650, owed its safety to the Poles, its brave and faithful allies. Such was the case; but, at this day, the Polish nation is no longer in existence: it is subdued, parcelled out, and divided, amongst those very powers, to any of which it was at least equal, and to the others superior, at so late a period. It may be asked, whether Poland was one of those states that has been borne down by its own wealth and opulence? If its ambition, injustice, or any of the other causes so prominent in the decline of nations, operated in the total extinction of it from the rank of independent states? Not one of those causes operated, but still it is not altogether an exception to the general rule. When the feudal system was established all over Europe, nations under its influence were so far on an equality; and as they all emerged from that situation nearly about the same time, Poland excepted, they still preserved their relative situations. The Poles, during this change in other states, comparatively lost power. Amongst the alterations produced, was that of placing in the hands of the sovereign all the disposable revenue and force of a country, with which standing armies were maintained. Those irregular militias, till then composed of the barons and their retainers; a species of force, at best, far inferior to regular armies, became useless; but particularly so, after the modes of fighting had been changed by the invention of gunpowder, and the adoption of large trains of artillery, which could never have been employed in the feudal armies.
