Joseph Story,
Commentaries on the Constitution of the United States
(1833)
“ It has been said, that the constitution allows only the means, which are necessary; not those, which are merely convenient for effecting the enumerated powers. If such a latitude of construction be given to this phrase, as to give any non-enumerated power, it will go far to give every one; for there is no one, which ingenuity might not torture into a convenience in some way or other to some one of so long a list of enumerated powers. ”
