Dear Sir
Montpellier April. 17 1824
I have been retarded in thanking you for the copy of your Speech on the subject of internal improvement, by a necessary absence from home, and by successive occurrences since my return. I now beg you to accept that debt to your kindness.
I have read your observations with a due perception of the ability which pervades & the eloquence which adorns them, and I must add not without the pleasure of noticing that you have pruned from the doctrines of some of your fellow labourers, its most luxuriant branches. I can not but think at the same time that you have left the root in too much vigour. This appears particularly in the question of Canals. My impression with respect to the authority to make them may be the stronger perhaps, (as I had occasion to remark as to the Bank on its original discussion) from my recollection that the authority had been repeatedly proposed in the Convention, and negatived either as improper to be vested in Congress, or as a power not likely to be yielded by the States. My impression is also very decided that if the construction which brings Canals within the scope of commercial regulations, had been advanced or admitted by the Advocates of the Constitution in the State Conventions, it would have been impossible to overcome the opposition to it. It is remarkable that Mr. Hamilton himself, the strenuous patron of an expansive meaning in the text of the Constitution, with the views of the Convention fresh in his memory, and in a Report contending for the most liberal rules of interpretation, was obliged by his candour to admit that they could not embrace the case of Canals.
In forbearing to exercise doubtful powers, especially where not immediately and manifestly necessary, I entirely agree with you. I view our political system also, as you do, as a combination & modification of powers without a model; as emphatically sui generis, of which one remarkable feature is its annihilation of a power inherent in some branch of all other Governments, that of taxing exports. I wish moreover that you might be followed in the example of defining the terms used in argument, the only effectual precaution against fruitless & endless discussion. This logical precept is peculiarly essential in debating Constitutional questions, to which for want of more appropriate words, such are often applied as lead to error & confusion. Known words express known ideas: and new ideas, such as are presented by our Novel and Unique political System, must be expressed either by new words, or by old words with new definitions. Without attention to this circumstance, volumes may be written which can only be answered by a call for definitions, and which answer themselves as soon as the call is complied with.
It can not be denied without forgetting what belongs to human nature, that in consulting the cotemporary writings, which vindicated and recommended the Constitution, it is fair to keep in mind that the Authors might be sometimes influenced by the zeal of advocates; But in expounding it now, is the danger of bias less, from the influence of local interests, of popular currents, and even from an estimate of national utility.
Having rambled thus far I venture on another devious step, by alluding to your inference from a passage in one of my messages, that in a subsequent one, my objection was not to the power, but to the details of the Bill in which it was exercised. If the language was not more carefully guarded against such an inference it must have been because I relied on a presumed notoriety of my opinion on the subject; and probably considered the terms “existing powers” as essentially satisfied by the uncontested authority of Congress over the Territories. With great esteem & friendly respects
James Madison
