The inconsistency of the institution of domestic slavery with the principles of the Declaration of Independence was seen and lamented . . . no insincerity or hypocrisy can be fairly laid to their charge. Never from their lips was heard one syllable of attempt to justify the institution of slavery. They universally considered it as a reproach fastened upon them by the unnatural step-mother country and they saw that before the principles of the Declaration of Independence slavery, in common with every other mode of oppression, was destined sooner or later to be banished from the earth.
John Quincy AdamsWhile dwelling with pleasing satisfaction upon the superior excellence of our political institutions, let us not be unmindful that liberty is power; that the nation blessed with the largest portion of liberty must in proportion to its numbers be the most powerful nation upon earth, and that the tenure of power by man is, in the moral purposes of his Creator, upon condition that it shall be exercised to ends of beneficence, to improve the condition of himself and his fellow men.
John Quincy AdamsThere are three points of doctrine the belief of which forms the foundation of all morality. The first is the existence of God; the second is the immortality of the human soul; and the third is a future state of rewards and punishments. Suppose it possible for a man to disbelieve either of these three articles of faith and that man will have no conscience, he will have no other law than that of the tiger or the shark. The laws of man may bind him in chains or may put him to death, but they never can make him wise, virtuous, or happy.
