Magic challenges our sense of what’s real; Houdini wanted to challenge the ultimate reality of death, by risking it over and over. That risk, he later wrote, is what “attracts us to the man who paints the flagstaff on the tall building, or to the ‘human fly,’ who scales the walls of the same building. If we knew that there was no possibility of either one of them falling or, if they did fall, that they wouldn’t injure themselves in any way, we wouldn’t pay any more attention to them than we do a nursemaid wheeling a baby carriage. – The New Yorker
