Or, if we want more of a philosophy of the matter than this, our free-trade friends have two axioms for us, axioms laid down by their justly esteemed doctors, which they think ought to satisfy us entirely.  One is, that, other things being equal, the more population increases, the more does production increase to keep pace with it; because men by their numbers and contact call forth all manner of activities and resources in one another and in nature, which, when men are few and sparse, are never developed.  The other is, that, although population always tends to equal the means of [234] subsistence, yet people’s notions of what subsistence is enlarge as civilisation advances, and take in a number of things beyond the bare necessaries of life; and thus, therefore, is supplied whatever check on population is needed.  But the error of our friends is just, perhaps, that they apply axioms of this sort as if they were self-acting laws which will put themselves into operation without trouble or planning on our part, if we will only pursue free-trade, business, and population zealously and staunchly.  Whereas the real truth is, that, however the case might be under other circumstances, yet in fact, as we now manage the matter, the enlarged conception of what is included in subsistence does not operate to prevent the bringing into the world of numbers of people who but just attain to the barest necessaries of life or who even fail to attain to them; while, again, though production may increase as population increases, yet it seems that the production may be of such a kind, and so related, or rather non-related, to population, that the population may be little the better for it.  For instance, with the increase of population since Queen Elizabeth’s time the production of silk-stockings has wonderfully increased, and silk- [235] stockings have become much cheaper and procurable in much greater abundance by many more people, and tend perhaps, as population and manufactures increase, to get cheaper and cheaper, and at last to become, according to Bastiat’s favourite image, a common free property of the human race, like light and air.  But bread and bacon have not become much cheaper with the increase of population since Queen Elizabeth’s time, nor procurable in much greater abundance by many more people; neither do they seem at all to promise to become, like light and air, a common free property of the human race.  And if bread and bacon have not kept pace with our population, and we have many more people in want of them now than in Queen Elizabeth’s time, it seems vain to tell us that silk-stockings have kept pace with our population, or even more than kept pace with it, and that we are to get our comfort out of that.  In short, it turns out that our pursuit of free-trade, as of so many other things, has been too mechanical.  We fix upon some object, which in this case is the production of wealth, and the increase of manufactures, population, and commerce through free-[236] trade, as a kind of one thing needful, or end in itself, and then we pursue it staunchly and mechanically, and say that it is our duty to pursue it staunchly and mechanically, not to see how it is related to the whole intelligible law of things and to full human perfection, or to treat it as the piece of machinery, of varying value as its relations to the intelligible law of things vary, which it really is.
