Famous quotes containing the word history:
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
“The history of all previous societies has been the history of class struggles.”
—Karl Marx (1818–1883)
“A man will not need to study history to find out what is best for his own culture.”
—Henry David Thoreau (1817–1862)
