Famous quotes containing the words life and/or culture:
“There is nothing so noble and so right as to play our human life well and fitly, nor anything so difficult to learn as how to live this life well and according to Nature.”
—Michel de Montaigne (1533–1592)
“As the end of the century approaches, all our culture is like the culture of flies at the beginning of winter. Having lost their agility, dreamy and demented, they turn slowly about the window in the first icy mists of morning. They give themselves a last wash and brush-up, their ocellated eyes roll, and they fall down the curtains.”
—Jean Baudrillard (b. 1929)
