From what I have said, two things result--1st, That the social sciences must abound more in sophisms than others, because in them each man takes counsel of his own judgment and instincts; 2d, That it is in these sciences that sophisms are especially mischievous, because they mislead public opinion, and in a matter, too, with reference to which public opinion is force, is law. In these sciences, then, we have need of two sorts of books, those which explain them, and those which further and advance them--those which establish truth, and those which combat error. It seems to me that the inherent fault of this little work, repetition, is exactly what will make it useful. In the question I have treated, each sophism has undoubtedly its own formula, and its special bearing, but all may be traced to a common root, which is, _forgetting men's interests as consumers_. To point out that a thousand errors may be traced to this prolific sophism, is to teach the public to detect it, to estimate it at its true worth, and to distrust it, under all circumstances. After all, the design of my present work is not exactly to implant convictions, but rather to awaken doubts. I have no expectation that the reader, on laying down the book, will exclaim _I know_; I would much rather that he should say candidly, _I am ignorant!_ "I am ignorant, for I begin to fear that there is something illusory in the flattering promises of scarcity." (Sophism I.) "I am not so much charmed with obstacles as I once was. (Sophism II.) "_Effort without result_ no longer appears to me so desirable as _result without effort_." (Sophism III.) "It is very possible that the secret of trade does not consist, like the secret of arms (if we adopt the definition of the bully in the _Bourgeois Gentilhomme_), in giving and not receiving." (Sophism VI.) "I can understand that a commodity is worth more in proportion as it has had more labour bestowed upon it; but in exchange, will two equal values cease to be equal values, because the one proceeds from the plough, and the other from the loom?" (Sophism XXI.) "I confess that I begin to think it singular that the human race should be improved by shackles, and enriched by taxes; and, truth to say, I should be relieved of a troublesome weight, I should experience unmitigated satisfaction, were it proved to me, as the author of the _Sophismes_ asserts, that there is no incompatibility between thriving circumstances and justice, between peace and liberty, between the extension of labour and the progress of intelligence." (Sophisms XIV. and XX.) "Then, without being quite convinced by his arguments, to which I know not whether to give the name of reasonings or of paradoxes, I shall apply myself to the acknowledged masters of the science." Let us conclude this monography of sophism with a final and important observation. The world is not sufficiently alive to the influence exercised over it by sophisms.
