I do not know if it has ever been noted before that one of the main characteristics of life is discreteness. Unless a film of flesh envelops us, we die. Man exists only insofar as he is separated from his surroundings. The cranium is a space-traveler’s helmet. Stay inside or you perish. Death is divestment, death is communion. It may be wonderful to mix with the landscape, but to do so is the end of the tender ego.
— Vladimir Nabokov, Pnin
