" are illustrations of the acknowledged truth here
asserted, that by the consent of the civilized world, and on the
principles of universal law, slaves are not "_property_," but
_self-proprietors_, and that whenever held as property under _law_, it
is only by _positive legislative acts_, forcibly setting aside the law
of nature, the common law, and the principles of universal justice and
right between man and man,--principles paramount to all law, and from
which alone law derives its intrinsic authoritative sanction.]

But waiving all concessions, whether of constitutions, laws, judicial
decisions, or common consent, I take the position that the power of
Congress to abolish slavery in the District, follows from the fact, that
as the sole legislature there, it has unquestionable power _to adopt the
Common Law, as the legal system within its exclusive jurisdiction_. This
has been done, with certain restrictions, in most of the States, either
by legislative acts or by constitutional implication. THE COMMON LAW
KNOWS NO SLAVES. Its principles annihilate slavery wherever they touch
it. It is a universal, unconditional, abolition act. Wherever slavery is
a legal system, it is so only by _statute_ law, and in violation of
common law. The declaration of Lord Chief Justice Holt, that "by the
common law, no man can have property in another," is an acknowledged
axiom, and based upon the well known common law definition of property.
"The subjects of dominion or property are _things_, as
contra-distinguished from _persons_." Let Congress adopt the common law
in the District of Columbia, and slavery there is at once abolished.
Congress may well be at home in common law legislation, for the common
law is the grand element of the United States Constitution. All its
_fundamental_ provisions are instinct with its spirit; and its
existence, principles and paramount authority, are presupposed and
assumed throughout the whole. The preamble of the Constitution plants
the standard of the Common Law immovably in its foreground. "We, the
people of the United States, in order to ESTABLISH JUSTICE, &c., do
ordain and establish this Constitution;" thus proclaiming _devotion to
justice_, as the controlling motive in the organization of the
Government, and its secure establishment the chief object of its aims.
By this most solemn recognition, the common law, that grand legal
embodiment of "_justice_" and fundamental right was made the groundwork
of
