SUMMARY
The handicap makes it possible to uncover the structure of humanism, which is not significant only for medicine, but also for the sciences in general. According to humanist opinion, the human being is complete. Because the person marked by disability is not able to fulfil the humanist norm of “being human”, (s)he should be supplemented by technical prosthesis. Yet the technical device could make it possible to see that the normative state of “being human” is also marked by certain forgotten technical presuppositions. In this paper I try to show the relevance of this insight for musicology.
