Marshall McLuhan, Ernst Kapp, and David Rothenberg have each written book-length studies developing theories of technology as an extension of bodily and mental faculties: tools act as prosthetics, amplifying the reach of arms or legs; computers extend memory, calculation, and other cognitive capacities. Philip Brey analyzes these extension theories and asks if the metaphor is valid. Do technologies truly stretch out innate human abilities, or is this mere rhetorical flair? Brey investigates whether there is a substantive sense in which gadgets and gizmos can be seen as extensions of natural human organs. As we increasingly integrate tech into our lives, addressing this question becomes pressing: where does the human end and the technical begin? Brey dives into this ambiguous intersection of person and product.
