Famous quotes containing the words magic and/or number:
“Both magic and religion are based strictly on mythological tradition, and they also both exist in the atmosphere of the miraculous, in a constant revelation of their wonder-working power. They both are surrounded by taboos and observances which mark off their acts from those of the profane world.”
—Bronislaw Malinowski (1884–1942)
“... in every State there are more women who can read and write than the whole number of illiterate male voters; more white women who can read and write than all Negro voters; more American women who can read and write than all foreign voters.”
—National Woman Suffrage Association. As quoted in History of Woman Suffrage, vol. 4, ch. 13, by Susan B. Anthony and Ida Husted Harper (1902)
