Does the farmer make his own clothes? Does the tailor produce the corn he consumes? Does your housekeeper continue to have your bread made at home, after she finds she can buy it cheaper from the baker? Do you resign the pen for the brush, to save your paying tribute to the shoeblack? Does the entire economy of society not rest upon the separation of employments, the division of labour—in a word, upon exchange? And what is exchange, but a calculation which we make with a view to discontinuing direct production in every case in which we find that possible, and in which indirect acquisition enables us to effect a saving in time and in effort?
It is not you, therefore, who are the men of practice, since you cannot point to a single human being who acts upon your principle.
But you will say, we never intended to make our principle a rule for individual relations. We perfectly understand that this would be to break up the bond of society, and would force men to live like snails, each in his own shell. All that we contend for is, that our principle regulates de facto, the regulations which obtain between the different agglomerations of the human family.
Well, I affirm that this principle is still erroneous. The family, the commune, the canton, the department, the province, are so many agglomerations, which all, without any exception, reject practically your principle, and have never dreamt of acting on it. All procure themselves, by means of exchange, those things which it would cost them dearer to procure by means of production. And nations would do the same, did you not hinder them by force.
We, then, are the men of practice and of experience; for we oppose to the restriction which you have placed exceptionally on certain international exchanges, the practice and experience of all individuals, and of all agglomerations of individuals, whose acts are voluntary, and can consequently be adduced as evidence. But you begin by constraining, by hindering, and then you lay hold of acts which are forced or prohibited, as warranting you to exclaim, "We have practice and experience on our side!"
You inveigh against our theory, and even against theories in general. But when you lay down a principle in opposition to ours, you perhaps imagine you are not proceeding on theory? Clear your heads of that idea. You in fact form a theory, as we do; but between your theory and ours there is this difference:
Our theory consists merely in observing universal facts, universal opinions; calculations and ways of proceeding which universally prevail; and in classifying these, and rendering them Co-ordinate, with a view to their being more easily understood.
Our theory is so little opposed to practice that it is nothing else but practice explained. We observe men acting as they are moved by the instinct of self-preservation and a desire for progress, and what they thus do freely and voluntarily we denominate political or social economy. We can never help repeating, that each individual man is practically an excellent economist, producing or exchanging according as he finds it more to his interest to produce or to exchange. Each, by experience, educates himself in this science; or rather the science itself is only this same experience accurately observed and methodically explained.
But on your side, you construct a theory in the worst sense of the word. You imagine, you invent, a course of proceeding which is not sanctioned by the practice of any living man under the canopy of heaven; and then you invoke the aid of constraint and prohibition. It is quite necessary that you should have recourse to force, for you desire that men should be made to produce those things which they find it more advantageous to buy; you desire that they should renounce this advantage, and act upon a doctrine which implies a contradiction in terms.
The doctrine which you acknowledge would be absurd in the relations of individuals; I defy you to extend it, even in speculation, to transaction between families, communities, or provinces. By your own admission, it is only applicable to international relations.
