I hold that the Federal Government was never, in its essence, anything but an anti-slavery government. Abolish slavery tomorrow, and not a sentence or syllable of the Constitution need be altered. It was purposely so framed as to give no claim, no sanction to the claim, of property in a man. If in its origin slavery had any relation to the government, it was only as the scaffolding to the magnificent structure, to be removed as soon as the building was completed.
