Famous quotes containing the words early, modern and/or period:

    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)

    We must open our eyes and see that modern civilization has become so complex and the lives of civilized men so interwoven with the lives of other men in other countries as to make it impossible to be in this world and out of it.
    Franklin D. Roosevelt (1882–1945)

But the day of reconstruction seems to be looming, and now the grand question is: Are there any sure and universal principles that will evolve a harmonious system in which we shall all agree?
    Catherine E. Beecher (1800–1878)
