To reasoning of this kind,--were it even more specious and plausible than this in our opinion is,--it would be a sufficient answer, that it is entirely of an abstract and speculative character, and affords of course no proper basis for important political action. It is, in fact, one of the most curious circumstances in this affair, that the leading Southern politicians have throughout founded their pretensions, and predicated the measures they recommend on principles, economical and political, not only wholly theoretical and vague, but before unheard of, broached by themselves for the first time, and repugnant to the received opinions of the whole practical and scientific world. Such is their doctrine, that the producer and not the consumer pays the taxes:--such is this of absolute and concurring majorities. The very language employed is entirely new. The phrase _concurring majority_, which, taken separately, is wholly unintelligible, and when explained as it is, involves a contradiction in terms, was, as far as we are informed, invented by Mr. Calhoun. Now we put it in perfect sincerity to the conscience of that gentleman and his political friends to say, whether it is fair and reasonable to expect, that the people of the United States will adopt instantaneously as a rule of action in the most important concerns, the new theories that may occur to a few citizens, however distinguished, in their abstract speculations on the sciences of politics and political economy. We cheerfully give full credit to the discoverers of these hitherto unheard of principles, for their talents, ingenuity and research, and should always listen with great attention to the suggestions they might make; but we cannot consent to receive them at once, and without reflection or examination, as infallible guides for conduct or even opinion. Before an abstract principle, however plausible it may appear, can be safely adopted as a basis of action in important matters, whether public or private, it must for a long time be canvassed, examined, opposed and defended, until it is finally admitted into the number of acknowledged and popular truths. We find, accordingly, that in the British Parliament, which affords the most illustrious example of deliberative legislation, no appeal is ever made to abstract principles, even such as are generally admitted. The argument turns entirely upon precedent and plain common sense. During the last fifteen or twenty years, propositions have been repeatedly made in the House of Commons of measures predicated on the pretended discoveries of Malthus, in regard to the law of population. But, although the belief in his doctrines was at one time nearly universal, and was probably shared by most of the members of Parliament, no measures predicated upon them could ever be got through. The event has fully justified this caution, the doctrine in question being now almost as universally rejected as it was at one time admitted. In the French
