Famous quotes containing the words historical and/or papers:
“Some minds are as little logical or argumentative as nature; they can offer no reason or “guess,” but they exhibit the solemn and incontrovertible fact. If a historical question arises, they cause the tombs to be opened. Their silent and practical logic convinces the reason and the understanding at the same time. Of such sort is always the only pertinent question and the only satisfactory reply.”
—Henry David Thoreau (1817–1862)
“To a historian libraries are food, shelter, and even muse. They are of two kinds: the library of published material, books, pamphlets, periodicals, and the archive of unpublished papers and documents.”
—Barbara Tuchman (1912–1989)
