Famous quotes containing the word setting:
“The world is ... the natural setting of, and field for, all my thoughts and all my explicit perceptions. Truth does not “inhabit” only “the inner man,” or more accurately, there is no inner man, man is in the world, and only in the world does he know himself.”
—Maurice Merleau-Ponty (1907–1961)
