Vladimir Nabokov (born 22 April, 1899; died 2 July 1977), photographed in New York by William Claxton, 1963
'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 envelopes 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.'
— from Pnin (1957)
