Famous quotes containing the words hard and/or problem:

    “He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.”
    —Ralph Waldo Emerson (1803–1882)

    “In the nineteenth century the problem was that God is dead; in the twentieth century the problem is that man is dead.”
    —Erich Fromm (1900–1980)
