Famous quotes containing the words earth and/or materials:
“Fit gravefellows you are for Lincoln, Brown
And Douglass and Toussaint. . . all whose rapt eyes
Fashioned a new world in this wilderness.
American earth is richer for your bones;
Our hearts beat prouder for the blood we inherit.”
—Dudley Randall (b. 1914)
“In how few words, for instance, the Greeks would have told the story of Abelard and Heloise, making but a sentence of our classical dictionary.... We moderns, on the other hand, collect only the raw materials of biography and history, “memoirs to serve for a history,” which is but materials to serve for a mythology.”
—Henry David Thoreau (1817–1862)
