I believe this government cannot endure permanently half slave and half free.

In giving freedom to the slave we assure freedom to the free,--honorable alike in what we give and what we preserve.

Those who deny freedom to others deserve it not for themselves, and, under a just God cannot retain it.

Those who deny freedom to others, deserve it not for themselves

The democracy of to-day hold the liberty of one man to be absolutely nothing when in conflict with another man's right of property...
This is a world of compensations; and he would -be- no slave must consent to -have- no slave. Those who deny freedom to others, deserve it not for themselves; and, under a just God, can not long retain it.
All honor to Jefferson - to the man who, in the concrete pressure of a struggle for national independence by a single people, had the coolness, forecast, and capacity to introduce into a merely revolutionary document, an abstract truth, applicable to all men and all times, and so embalm it there, that to-day, and in all coming days, it shall be a rebuke and a stumbling-block to the very harbingers of re-appearing tyranny and oppression. Your obedient Servant,
[Abraham Lincoln]
April 6, 1859, in a letter to MA State Rep Henry L. Pierce
Springfield, Ill.

"We must free the slaves or be ourselves subdued. The slaves were undeniably a element of strength to those who had their service, and we must decide whether that element should be with us or "against us". Emancipation, will strike at the heart of the rebellion." Said to Secretary of the Navy Gideon Welles.
