d a "perpetual motion." A single individual might
thus perpetuate slavery in defiance of the expressed will of a whole
people. The most common form of this fallacy is given by Mr. Wise, of
Virginia, in his speech, February 16, 1835, in which he denied the power
of Congress to abolish slavery in the District, unless the inhabitants
owning slaves petitioned for it!! Southern members of Congress at the
present session (1837-8) ring changes almost daily upon the same
fallacy. What! pray Congress _to use_ a power which it _has not_? "It is
required of a man according to what he _hath_," saith the Scripture. I
commend Mr. Wise to Paul for his ethics. Would that he had got his
_logic_ of him! If Congress does not possess the power, why taunt it
with its weakness, by asking its exercise? Petitioning, according to Mr.
Wise, is, in matters of legislation, omnipotence itself; the very
_source_ of all constitutional power; for, _asking_ Congress to do what
it _cannot_ do, gives it the power!--to pray the exercise of a power
that is _not, creates_ it! A beautiful theory! Let us work it both ways.
If to petition for the exercise of a power that is _not_, creates it--to
petition against the exercise of a power that _is_, annihilates it. As
southern gentlemen are partial to summary processes, pray, sirs, try the
virtue of your own recipe on "exclusive legislation in all cases
whatsoever;" a better subject for experiment and test of the
prescription could not be had. But if the petitions of the citizens of
the District give Congress the _right_ to abolish slavery, they impose
the _duty_; if they confer constitutional _authority_, they create
constitutional _obligation_. If Congress _may_ abolish because of an
expression of their will, it _must_ abolish at the bidding of that will.
If the people of the District are a _source of power_ to Congress, their
_expressed will_ has the force of a constitutional provision, and has
the same binding power upon the National Legislature. To make Congress
dependent on the District for authority, is to make it a _subject_ of
its authority, restraining the exercise of its own discretion, and
sinking it into a mere organ of the District's will. We proceed to
another objection.

"_The southern states would not have ratified the constitution, if they
had supposed that it gave this power_." It is a sufficient answer to
this objection, that the northern states would not have ratified it, if
they had supposed
