Famous quotes containing the word history:
“The reverence for the Scriptures is an element of civilization, for thus has the history of the world been preserved, and is preserved.”
—Ralph Waldo Emerson (18031882)
“History takes time.... History makes memory.”
—Gertrude Stein (18741946)
“Books of natural history aim commonly to be hasty schedules, or inventories of Gods property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.”
—Henry David Thoreau (18171862)
