Famous quotes containing the words smooth and/or structure:

    Less smooth than her Skin and less white than her breast
    Was this pollisht stone beneath which she lyes prest
    Stop, Reader, and Sigh while thou thinkst on the rest

    With a just trim of Virtue her Soul was endu’d
    Not affectedly Pious nor secretly lewd,
    She cut even between the Cocquet and the Prude.
    Matthew Prior (1664–1721)

    ... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.
    Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
