It can hardly be doubted that there must have been some great fallacy in the notions of those who uttered and of those who believed that long succession of confident predictions, so signally falsified by a long succession of indisputable facts. To point out that fallacy is the office rather of the political economist than of the historian. Here it is sufficient to say that the prophets of evil were under a double delusion. They erroneously imagined that there was an exact analogy between the case of an individual who is in debt to another individual and the case of a society which is in debt to a part of itself; and this analogy led them into endless mistakes about the effect of the system of funding. They were under an error not less serious touching the resources of the country. They made no allowance for the effect produced by the incessant progress of every experimental science, and by the incessant efforts of every man to get on in life. They saw that the debt grew; and they forgot that other things grew as well as the debt. A long experience justifies us in believing that England may, in the twentieth century, be better able to bear a debt of sixteen hundred millions than she is at the present time to bear her present load. But be this as it may, those who so confidently predicted that she must sink, first under a debt of fifty millions, then under a debt of eighty millions then under a debt of a hundred and forty millions, then under a debt of two hundred and forty millions, and lastly under a debt of eight hundred millions, were beyond all doubt under a twofold mistake. They greatly overrated the pressure of the burden; they greatly underrated the strength by which the burden was to be borne.
