James Madison in Federalist No. 37:
"The novelty of the undertaking immediately strikes us. It has been shown in the course of these papers, that the existing Confederation is founded on principles which are fallacious; that we must consequently change this first foundation, and with it the superstructure resting upon it. It has been shown, that the other confederacies which could be consulted as precedents have been vitiated by the same erroneous principles, and can therefore furnish no other light than that of beacons, which give warning of the course to be shunned, without pointing out that which ought to be pursued. The most that the convention could do in such a situation, was to avoid the errors suggested by the past experience of other countries, as well as of our own; and to provide a convenient mode of rectifying their own errors, as future experiences may unfold them.
"Among the difficulties encountered by the convention, a very important one must have lain in combining the requisite stability and energy in government, with the inviolable attention due to liberty and to the republican form. Without substantially accomplishing this part of their undertaking, they would have very imperfectly fulfilled the object of their appointment, or the expectation of the public; yet that it could not be easily accomplished, will be denied by no one who is unwilling to betray his ignorance of the subject. Energy in government is essential to that security against external and internal danger, and to that prompt and salutary execution of the laws which enter into the very definition of good government. Stability in government is essential to national character and to the advantages annexed to it, as well as to that repose and confidence in the minds of the people, which are among the chief blessings of civil society. An irregular and mutable legislation is not more an evil in itself than it is odious to the people; and it may be pronounced with assurance that the people of this country, enlightened as they are with regard to the nature, and interested, as the great body of them are, in the effects of good government, will never be satisfied till some remedy be applied to the vicissitudes and uncertainties which characterize the State administrations. On comparing, however, these valuable ingredients with the vital principles of liberty, we must perceive at once the difficulty of mingling them together in their due proportions. The genius of republican liberty seems to demand on one side, not only that all power should be derived from the people, but that those intrusted with it should be kept in dependence on the people, by a short duration of their appointments; and that even during this short period the trust should be placed not in a few, but a number of hands. Stability, on the contrary, requires that the hands in which power is lodged should continue for a length of time the same. A frequent change of men will result from a frequent return of elections; and a frequent change of measures from a frequent change of men: whilst energy in government requires not only a certain duration of power, but the execution of it by a single hand."
