Famous quotes containing the word history:
“... in a history of spiritual rupture, a social compact built on fantasy and collective secrets, poetry becomes more necessary than ever: it keeps the underground aquifers flowing; it is the liquid voice that can wear through stone.”
—Adrienne Rich (b. 1929)
“History does nothing; it does not possess immense riches, it does not fight battles. It is men, real, living, who do all this.... It is not history which uses men as a means of achievingas if it were an individual personits own ends. History is nothing but the activity of men in pursuit of their ends.”
—Karl Marx (18181883)
“The history is always the same the product is always different and the history interests more than the product. More, that is, more. Yes. But if the product was not different the history which is the same would not be more interesting.”
—Gertrude Stein (18741946)
