Famous quotes containing the word problem:

    The problem of induction is not a problem of demonstration but a problem of defining the difference between valid and invalid
    predictions.
    Nelson Goodman (1906)

    We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.
    Lyndon Baines Johnson (1908–1973)

    One thing in any case is certain: man is neither the oldest nor the most constant problem that has been posed for human knowledge.
    Michel Foucault (1926–1984)
