Famous quotes containing the words life and/or culture:
“Worst, when this sensualism intrudes into the education of young women, and withers the hope and affection of human nature, by teaching that marriage signifies nothing but a housewife’s thrift, and that woman’s life has no other aim.”
—Ralph Waldo Emerson (1803–1882)
“The best hopes of any community rest upon that class of its gifted young men who are not encumbered with large possessions.... I now speak of extensive scholarship and ripe culture in science and art.... It is not large possessions, it is large expectations, or rather large hopes, that stimulate the ambition of the young.”
—Rutherford Birchard Hayes (1822–1893)
