“ Would the people of any one State trust those of another with a power to control the most insignificant operations of their State Government? We know they would not. Why, then, should we suppose that the people of any one State should be willing to trust those of another with a power to control the operations of a Government to which they have confided their most important and most valuable interests? ”

“ The subject is the execution of those great powers on which the welfare of a Nation essentially depends. It must have been the intention of those who gave these powers to insure, so far as human prudence could insure, their beneficial execution. This could not be done by confiding the choice of means to such narrow limits as not to leave it in the power of Congress to adopt any which might be appropriate, and which were conducive to the end. This provision is made in a Constitution intended to endure for ages to come, and consequently to be adapted to the various crises of human affairs. ”

“ We admit, as all must admit, that the powers of the Government are limited, and that its limits are not to be transcended. But we think the sound construction of the Constitution must allow to the national legislature that discretion with respect to the means by which the powers it confers are to be carried into execution which will enable that body to perform the high duties assigned to it in the manner most beneficial to the people. ”

“ That the power to tax involves the power to destroy; that the power to destroy may defeat and render useless the power to create; that there is a plain repugnance in conferring on one Government a power to control the constitutional measures of another, which other, with respect to those very measures, is declared to be supreme over that which exerts the control, are propositions not to be denied. But all inconsistencies are to be reconciled by the magic of the word CONFIDENCE. Taxation, it is said, does not necessarily and unavoidably destroy. ”

“ But it may with great reason be contended that a Government intrusted with such ample powers, on the due execution of which the happiness and prosperity of the Nation so vitally depends, must also be intrusted with ample means for their execution. The power being given, it is the interest of the Nation to facilitate its execution. It can never be their interest, and cannot be presumed to have been their intention, to clog and embarrass its execution by withholding the most appropriate means. ”

“ How far it has been controlled by that instrument must be a question of construction. In making this construction, no principle, not declared, can be admissible which would defeat the legitimate operations of a supreme Government. It is of the very essence of supremacy to remove all obstacles to its action within its own sphere, and so to modify every power vested in subordinate governments as to exempt its own operations from their own influence. ”

“ But it is conceived that a doubtful question, one on which human reason may pause and the human judgment be suspended, in the decision of which the great principles of liberty are not concerned, but the respective powers of those who are equally the representatives of the people, are to be adjusted, if not put at rest by the practice of the Government, ought to receive a considerable impression from that practice. An exposition of the Constitution, deliberately established by legislative acts, on the faith of which an immense property has been advanced, ought not to be lightly disregarded. ”

“ A Constitution, to contain an accurate detail of all the subdivisions of which its great powers will admit, and of all the means by which they may be carried into execution, would partake of the prolixity of a legal code, and could scarcely be embraced by the human mind. ”

“ No political dreamer was ever wild enough to think of breaking down the lines which separate the States, and of compounding the American people into one common mass. Of consequence, when they act, they act in their States. But the measures they adopt do not, on that account, cease to be the measures of the people themselves, or become the measures of the State governments.
From these conventions the Constitution derives its whole authority. The government proceeds directly from the people ”

“ If a corporation may be employed, indiscriminately with other means, to carry into execution the powers of the Government, no particular reason can be assigned for excluding the use of a bank, if required for its fiscal operations. To use one must be within the discretion of Congress if it be an appropriate mode of executing the powers of Government. ”

“ That a legislature, endowed with legislative powers, can legislate is a proposition too self-evident to have been questioned.
But the argument on which most reliance is placed is drawn from that peculiar language of this clause. Congress is not empowered by it to make all laws which may have relation to the powers conferred on the Government, but such only as may be "necessary and proper" for carrying them into execution. ”

“ To impose on it the necessity of resorting to means which it cannot control, which another Government may furnish or withhold, would render its course precarious, the result of its measures uncertain, and create a dependence on other Governments which might disappoint its most important designs, and is incompatible with the language of the Constitution. But were it otherwise, the choice of means implies a right to choose a national bank in preference to State banks, and Congress alone can make the election. ”

“ To employ the means necessary to an end is generally understood as employing any means calculated to [p414] produce the end, and not as being confined to those single means without which the end would be entirely unattainable. Such is the character of human language that no word conveys to the mind in all situations one single definite idea, and nothing is more common than to use words in a figurative sense. ”

“ It may be said with some plausibility that the right to carry the mail, and to punish those who rob it, is not indispensably necessary to the establishment of a post office and post road. This right is indeed essential to the beneficial exercise of the power, but not indispensably necessary to its existence. ”

“ In considering this question, then, we must never forget that it is a Constitution we are expounding. ”

“ The several powers of Congress may exist in a very imperfect State, to be sure, but they may exist and be carried into execution, although no punishment should be inflicted, in cases where the right to punish is not expressly given. ”

“ This Government is acknowledged by all to be one of enumerated powers. The principle that it can exercise only the powers granted to it would seem too apparent to have required to be enforced by all those arguments which its enlightened friends, while it was depending before the people, found it necessary to urge; that principle is now universally admitted. But the question respecting the extent of the powers actually granted is perpetually arising, and will probably continue to arise so long as our system shall exist. ”

“ If reference be had to its use in the common affairs of the world or in approved authors, we find that it frequently imports no more than that one thing is convenient, or useful, or essential to another. ”

“ Almost all compositions contain words which, taken in a their rigorous sense, would convey a meaning different from that which is obviously intended. It is essential to just construction that many words which import something excessive should be understood in a more mitigated sense — in that sense which common usage justifies. ”

“ The different departments may be established; taxes may be imposed and collected; armies and navies may be raised and maintained; and money may be borrowed, without requiring an oath of office. It might be argued with as much plausibility as other incidental powers have been assailed that the convention was not unmindful of this subject. The oath which might be exacted — that of fidelity to the Constitution — is prescribed, and no other can be required. ”
