Famous quotes containing the words dangerous and/or materials:
“I am afraid if there is anything to be afraid of. A precipice cannot hurt you. Lions and tigers can. The streets of New York I consider more dangerous than the Matterhorn to a thoroughly competent and careful climber.”
—Annie Smith Peck (1850–1935)
“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)
