Famous quotes containing the words natural and/or materials:
“Unfortunately there is still a cultural stereotype that it’s all right for girls to be affectionate but that once boys reach six or seven, they no longer need so much hugging and kissing. What this does is dissuade boys from expressing their natural feelings of tenderness and affection. It is important that we act affectionately with our sons as well as our daughters.”
—Stephanie Martson (20th century)
“What is most interesting and valuable in it, however, is not the materials for the history of Pontiac, or Braddock, or the Northwest, which it furnishes; not the annals of the country, but the natural facts, or perennials, which are ever without date. When out of history the truth shall be extracted, it will have shed its dates like withered leaves.”
—Henry David Thoreau (1817–1862)
