in legal contemplation the Union is perpetual confirmed by the history
of the Union itself. The Union is much older than the Constitution. It
was formed, in fact, by the Articles of Association in 1774. It was
matured and continued by the Declaration of Independence in 1776. It
was further matured, and the faith of all the then thirteen States
expressly plighted and engaged that it should be perpetual, by the
Articles of Confederation in 1778. And finally, in 1787, one of the
declared objects for ordaining and establishing the Constitution was
"to form a more perfect Union."

But if destruction of the Union by one or by a part only of the States
be lawfully possible, the Union is less perfect than before the
Constitution, having lost the vital element of perpetuity.

It follows from these views that no State upon its own mere motion can
lawfully get out of the Union; that resolves and ordinances to that
effect are legally void, and that acts of violence within any State or
States against the authority of the United States are insurrectionary
or revolutionary, according to circumstances.

I therefore consider that in view of the Constitution and the laws the
Union is unbroken, and to the extent of my ability, I shall take care,
as the Constitution itself expressly enjoins upon me, that the laws of
the Union be faithfully executed in all the States. Doing this I deem
to be only a simple duty on my part, and I shall perform it so far as
practicable unless my rightful masters, the American people, shall
withhold the requisite means or in some authoritative manner direct the
contrary. I trust this will not be regarded as a menace, but only as
the declared purpose of the Union that it will constitutionally defend
and maintain itself.
