The great renewal of the world will perhaps consist in this, that man and maid, freed of all false feelings and reluctances, will seek each other not as opposites, but as brother and sister, as neighbors, and will come together as human beings.
(Rainer Maria Rilke (1875-1926), German poet. Letter, July 16, 1903. Letters to a Young Poet (1934, rev. 1954).)
I think that Nature meant kindly when she made our brothers few. However, my voice is still for peace.
(Henry David Thoreau (1817-1862), U.S. philosopher, author, naturalist. Letter, November 14, 1847, to Ralph Waldo Emerson, in The Writings of Henry David Thoreau, vol. 6, p. 141, Houghton Mifflin (1906).)
If you are ready to leave father and mother, and brother and sister, and wife and child and friends, and never see them again,if you have paid your debts and made your will, and settled all your affairs, and are a free man, then you are ready for a walk.
(Henry David Thoreau (1817-1862), U.S. philosopher, author, naturalist. "Walking" (1862), in The Writings of Henry David Thoreau, vol. 5, p. 206, Houghton Mifflin (1906).)
