“Between women love is contemplative; caresses are intended less to gain possession of the other than gradually to re-create the self through her; separateness is abolished, there is no struggle, no victory, no defeat; in exact reciprocity each is at once subject and object, sovereign and slave; duality become mutuality.”
—Simone De Beauvoir (1908–1986)
““Teacher, which commandment in the law is the greatest?” He said to him, “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the greatest and first commandment. And a second is like it: You shall love your neighbor as yourself.’ On these two commandments hang all the law and the prophets.””
—Bible: New Testament, Matthew 22:36-40.
“It could be clearly proved that by a practical nullification [by the South] of the Fifteenth Amendment the Republicans have for several years been deprived of a majority in both the House and Senate. The failure of the South to faithfully observe the Fifteenth Amendment is the cause of the failure of all efforts towards complete pacification. It is on this hook that the bloody shirt now hangs.”
—Rutherford Birchard Hayes (1822–1893)
