« A handicap [...] is any limitation of activity or restriction of social life endured by a person in his/her environment because of a substantial long-term or a definitive alteration of one or several physical, sensory, mental, cognitive or psychological function [...] » (Loi 2005-102 du 12 février 2005). This reminder from French law points to two essential concepts: disability (alteration of capability) and handicap (repercussion of this disability in a social context). What is being referred to in this law is the possibility of leading a "normal" life. With this in mind, is it possible to think of enhancement in terms that do not suggest an "overcapacity" or "superhuman" performance? How does one establish the distinction between normal human abilities and overcapacity? Concerning the legal statutes that require a compensation of handicaps with an aim towards equality, how should we deal with the sudden appearance of forms of compensation that lead to overcapacitation, thus creating a new type of inequality? We are reminded of the peculiar situation of the athlete Oscar Pistorius, who was initially barred from competing with able-bodied athletes at the 2008 Olympic Games held in Beijing by the IAAF, because of the "evident mechanic advantage" acquired by running with prosthetic legs. On the other hand, how should we approach the situation of persons with normal capabilities who, in certain contexts, are expected to furnish greater efforts, as testified by recent interest in coaching or in the use of psychostimulants (smart drugs)?
