“One of the best ways of enslaving a people is to keep them from education… The second way of enslaving a people is to suppress the sources of information, not only by burning books but by controlling all the other ways in which ideas are transmitted.”

Context: There is more than one way to burn a book. And the world is full of people running about with lit matches. Every minority, be it Baptist/Unitarian, Irish/Italian/Octogenarian/Zen Buddhist, Zionist/Seventh-day Adventist, Women's Lib/Republican, Mattachine/FourSquareGospel feels it has the will, the right, the duty to douse the kerosene, light the fuse. Every dimwit editor who sees himself as the source of all dreary blanc-mange plain porridge unleavened literature, licks his guillotine and eyes the neck of any author who dares to speak above a whisper or write above a nursery rhyme.

1860s, Speech at Hartford (1860)
Context: The proposition that there is a struggle between the white man and the negro contains a falsehood. There is no struggle. If there was, I should be for the white man. If two men are adrift at sea on a plank which will bear up but one, the law justifies either in pushing the other off. I never had to struggle to keep a negro from enslaving me, nor did a negro ever have to fight to keep me from enslaving him. They say, between the crocodile and the negro they go for the negro. The logical proportion is therefore; as a white man is to a negro, so is a negro to a crocodile; or, as the negro may treat the crocodile, so the white man may treat the negro. The 'don't care' policy leads just as surely to nationalizing slavery as Jeff Davis himself, but the doctrine is more dangerous because more insidious.
