Famous quotes containing the words smart and/or materials:
“For he purrs in thankfulness, when God tell him he’s a good Cat.
For he is an instrument for the children to learn benevolence upon.”
—Christopher Smart (1722–1771)
“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)
