Famous quotes containing the words materials and/or metals:
“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)
“As in digging for precious metals in the mines, much earthy rubbish has first to be troublesomely handled and thrown out; so, in digging in one’s soul for the fine gold of genius, much dullness and common-place is first brought to light.”
—Herman Melville (1819–1891)
