Famous quotes containing the words natural and/or materials:
“BOSWELL “ ... Is not the fear of death natural to man?” JOHNSON. “So much so, Sir, that the whole of life is but keeping away the thought of it.””
—Samuel Johnson (1709–1784)
“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)
