“Professors could silence me then; they had figures, *diagrams*, maps, books.... I was learning that books and *diagrams* can be evil things if they deaden the mind of man and make him blind or cynical before subjection of any kind.”

—Agnes Smedley (1890–1950)

“If that’s the world’s smartest man, God help us.”

—Lucille *Feynman*, mother of American physicist Richard *Feynman* (1918-1988)
