Famous quotes containing the words standard and, standard and/or amendments:
“... the meanest life, the poorest existence, is attributed to God’s will, but as human beings become more affluent, as their living standard and style begin to ascend the material scale, God descends the scale of responsibility at a commensurate speed.”
—Maya Angelou (b. 1928)
“[The Declaration of Independence] meant to set up a standard maxim for free society, which should be familiar to all, and revered by all; constantly looked to, constantly labored for, and even though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people of all colors everywhere.”
—Abraham Lincoln (1809–1865)
“Both of us felt more anxiety about the South—about the colored people especially—than about anything else sinister in the result. My hope of a sound currency will somehow be realized; civil service reform will be delayed; but the great injury is in the South. There the Amendments will be nullified, disorder will continue, prosperity to both whites and colored people will be pushed off for years.”
—Rutherford Birchard Hayes (1822–1893)
