Generally speaking, history taught them two lessons. Ancient history taught that nations rose and fell. When they fell, it was not from external conquest but from internal corruption. The process of corruption and decay was clearly understood: it took place when a people lost its virtue—virtue, in the original Latin sense, meaning manliness and being closely related to virility. The opposite of virtue was effeminacy, a term that was used interchangeably with vice, corruption, softness, and love of luxury. Once a nation started down the road to a love of luxury, it was doomed; only sumptuary legislation might save it, but sumptuary legislation usually came too late. A related danger was the resort to standing armies—partly because a standing army was inherently inimical to liberty, partly because it required a large and continuous public expenditure, which increased debts and taxes and thereby contributed to luxury—but mainly because it entailed a most unmanly shifting of responsibility for one’s own defense to the hands of others.
What an important viewpoint. We don't learn this in school.
