...Thus if you ask me, „Should I rouse that man or let him sleep on and be happy?“ I would answer that happiness signifies nothing to me. „Yet,“ I would add, „if an Aurora Borealis kindled in the skies, would you let your friend sleep on? Surely none should sleep when such a wonder may greet his eyes. True, that friend of yours is enjoying his sleep, nay, wallowing in it; yet your would be kinder to wrench him from his happy torpor and hale him outdoors, so that he may become. (Antoine de Saint-Exupéry – The Wisdom of the Sands)
