McCulloch, writing in 1838, says, in Note IV to "Wealth of Nations:"
"The wonderful density of population in Ireland is the immediate cause of the abject poverty and depressed condition of the great bulk of the people. It is not too much to say that there are at present more than double the persons in Ireland it is, with its existing means of production, able either fully to employ or to maintain in a moderate state of comfort."
As in 1841 the population of Ireland was given as 8,175,124, we may set it down in 1838 as about eight millions. Thus, to change McCulloch's negative into an affirmative, Ireland would, according to the over-population theory, have been able to fully employ and maintain in a moderate state of comfort something less than four million persons. Now, in the early part of the preceding contury, when Dean Swift wrote his "Modest Proposal," the population of Ireland was about two millions. As neither the means nor the arts of production had perceptibly advanced in Ireland during the interval, then—if the abject poverty and depressed condition of the Irish people in 1838 were attributable to over-population—there should, upon McCulloch's own admission, have been in Ireland in 1727 more than full employment, and much more than a moderate state of comfort, for the whole two millions. Yet, instead of this being the case, the abject poverty and depressed condition of the Irish people in 1727 were such, that, with burning, blistering irony, Dean Swift proposed to relieve surplus population by cultivating a taste for roasted babies, and bringing yearly to the shambles, as dainty food for the rich, 100,000 Irish infants!
It is difficult for one who has been looking over the literature of Irish misery, as while writing this chapter I have been doing, to speak in decorous terms of the complacent attribution of Irish want and suffering to over-population which are to be found even in the works of such high-minded men as Mill and Buckle. I know of nothing better calculated to make the blood boil than the cold accounts of the grasping, grinding tyranny to which the Irish people have been subjected, and to which, and not to any inability
