John Adams on Slavery

“Every measure of prudence, therefore, ought to be assumed for the eventual total extirpation of slavery.”

“Let us see delineated before us the true map of man. Let us hear the dignity of his nature, and the noble rank he holds among the works of God—that consenting to slavery is a sacrilegious breach of trust, as offensive in the sight of God as it is derogatory from our own honor or interest or happiness.”

“I Shall not pause to consider whether my Opinion will be popular or unpopular with the Slave Holders, or Slave Traders, in the Northern the Middle, the Southern, or the Western, States—I respect all those who are necessarily subjected to this Evil.—But Negro Slavery is an evil of Colossal Magnitude. … I am therefore utterly averse to the admission of Slavery into the Missouri Territory, and heartily wish that every Constitutional measure may be adopted for the preservation of it.”
