Famous quotes containing the words challenges and/or food:

    The approval of the public is to be avoided like the plague. It is absolutely essential to keep the public from entering if one wishes to avoid confusion. I must add that the public must be kept panting in expectation at the gate by a system of challenges and provocations.
    André Breton (1896–1966)

    Life is a thin narrowness of taken-for-granted, a plank over a canyon in a fog. There is something under our feet, the taken-for-granted. A table is a table, food is food, we are we—because we don’t question these things. And science is the enemy because it is the questioner. Faith saves our souls alive by giving us a universe of the taken-for-granted.
    Rose Wilder Lane (1886–1968)
