Famous quotes containing the words development and/or history:

    “If you complain of people being shot down in the streets, of the absence of communication or social responsibility, of the rise of everyday violence which people have become accustomed to, and the dehumanization of feelings, then the ultimate development on an organized social level is the concentration camp.... The concentration camp is the final expression of human separateness and its ultimate consequence. It is organized abandonment.”
    —Arthur Miller (b. 1915)

    “Properly speaking, history is nothing but the crimes and misfortunes of the human race.”
    —Pierre Bayle (1647–1706)
