Famous quotes containing the words common and/or designs:
“It was common practice for me to take my children with me whenever I went shopping, out for a walk in a white neighborhood, or just felt like going about in a white world. The reason was simple enough: if a black man is alone or with other black men, he is a threat to whites. But if he is with children, then he is harmless, adorable.”
—Gerald Early (20th century)
“His designs were strictly honourable, as the phrase is; that is, to rob a lady of her fortune by way of marriage.”
—Henry Fielding (1707–1754)
