Capital and labor being given, the result is, a sum of production, always the less great, in proportion as obstacles are numerous. There can be no doubt that protective tariffs, by forcing capital and labor to struggle against greater difficulties of soil and climate, must cause the general production to be less, or, in other words, diminish the portion of comforts which would thence result to mankind. If, then, there be a general diminution of comforts, how, workmen, can it be possible that _your_ portion should be increased? Under such a supposition, it would be necessary to believe that the rich, those who made the law, have so arranged matters, that not only they subject themselves to their own proportion of the general loss, but taking the whole of it upon themselves, that they submit also to a further loss, in order to increase your gains. Is this credible? Is this possible? It is, indeed, a most suspicious act of generosity, and if you act wisely, you will reject it. XIII. THEORY--PRACTICE. Partisans of free trade, we are accused of being theorists, and not relying sufficiently upon practice. What a powerful argument against Mr. Say (says Mr. Ferrier,) is the long succession of distinguished ministers, the imposing league of writers who have all differed from him; and Mr. Say is himself conscious of this, for he says: "It has been said, in support of old errors, that there must necessarily be some foundation for ideas so generally adopted by all nations. Ought we not, it is asked, to distrust observations and reasoning which run counter to every thing which has been looked upon as certain up to this day, and which has been regarded as undoubted by so many who were to be confided in, alike on account of their learning and of their philanthropic intentions? This argument is, I confess, calculated to make a profound impression, and might cast a doubt upon the most incontestable facts, if the world had not seen so many opinions, now universally recognized as false, as universally maintain, during a long series of ages, their dominion over the human mind. The day is not long passed since all nations, from the most ignorant to the most enlightened, and all men, the wisest as well as the most uninformed, admitted only four elements. Nobody dreamed of disputing this doctrine, which is, nevertheless, false, and to-day universally decried." Upon this passage Mr. Ferrier makes the following remarks:
