    “That Dali is really Norman Rockwell’s twin brother kidnapped by gypsies in babyhood.”
    —Vladimir Nabokov (1899–1977)

    “Views of women, on one side, as inwardly directed toward home and family and notions of men, on the other, as outwardly striving toward fame and fortune have resounded throughout literature and in the texts of history, biology, and psychology until they seem uncontestable. Such dichotomous views defy the complexities of individuals and stifle the potential for people to reveal different dimensions of themselves in various settings.”
    —Sara Lawrence Lightfoot (20th century)

    “I would advise you Sir, to study algebra, if you are not already an adept in it: your head would be less muddy, and you will leave off tormenting your neighbours about paper and packthread, while we all live together in a world that is bursting with sin and sorrow.”
    —Samuel Johnson (1709–1784)
