THE SAGE of
Monticello
Thomas Jefferson to John Holmes
22 April 1820
“This momentous
question, like a fire
bell in the night,
awakened and
filled me with
terror…”
“I considered it
at once as the
knell of the
Union.”

n. the sound of a bell, especially
when rung solemnly for a
death or funeral.
“It is hushed indeed for the moment.
but this is a reprieve only, not a final
sentence. a geographical line,
coinciding with a marked principle,
moral and political, once conceived
and held up to the angry passions of
men, will never be obliterated; and
every new irritation will mark it
deeper and deeper.”
I can say with conscious truth that there is not a
man on earth who would sacrifice more than I
would, to relieve us from this heavy reproach, in
any practicable way.
Johnson Eastman, The Lord is My Shepherd (1863)
Johnson Eastman, The Lord is My Shepherd (1863)
A general emancipation and expatriation
could be effected: and, gradually, and with
due sacrifices, I think it might be.

“I regret that I am now to die in
the belief that the useless
sacrifice of themselves, by the
generation of ‘76. to acquire
self government and happiness
to their country, is to be thrown
away by the unwise and
unworthy passions of their
sons…”
“My only consolation is to be that I
live not to weep over it. if they
would but dispassionately weigh the
blessings they will throw away
against an abstract principle more
likely to be effected by union than by
scission, they would pause before
they would perpetrate this act of
suicide on themselves and of treason
against the hopes of the world.”
ANTEBELLUM
1820-1860
A South Carolina Perspective…
During the debate,
Charles Pinckney (SC)
defended slavery as a
positive good.
Pinckney’s opinions did not hold much water
outside of South Carolina at the time, but as
Northerners continued to criticize slavery, more
Southerners began to defend the institution.

LET’S REVIEW:
Admit Missouri as a
Slave State.
Admit Maine as a
Free State.
Prohibit slavery in
