Famous quotes containing the words shafts and/or access:

    It was undoubtedly the feeling of exile—that sensation of a void within which never left us, that irrational longing to hark back to the past or else to speed up the march of time, and those keen shafts of memory that stung like fire.
    Albert Camus (1913–1960)

    The last publicized center of American writing was Manhattan. Its writers became known as the New York Intellectuals.
