Ventriloquism, the art of "seeming to speak where one is not", speaks so resonantly to our contemporary technological condition. We now think nothing of hearing voices--our own and others'--propelled over intercoms, cellphones, and answering machines. Yet, why can none of us hear our own recorded voice without wincing? Why is the telephone still full of such spookiness and erotic possibility? And why does the magician's trick of speaking through a dummy entertain as well as disturb us? These are the kind of questions which impel Dumbstruck, Steven Connor's wide-ranging, relentlessly inquisitive history of ventriloquism and the disembodied voice.
