Other critics of biomedical enhancements that appeal to considerations of authenticity acknowledge that enhanced individuals do author their accomplishments, but question whether those successes carry the same value as “authentic” unenhanced achievements (Habermas 2003; Sandel 2007; Bublitz and Merkel 2009). They maintain that when a marathon runner gains endurance chemically rather than through training, or when a mystic gains Nirvana through psychosurgery rather than meditation, each misses the point of these types of accomplishments. In the cases of marathon running and meditation, the outcomes of the activity cannot be separated from the activity itself: the value of the accomplishment lies in the personal activities they reward as well as the benefits they bring (Schermer 2008a; Spitzley 2018). However, even if these criticisms show that authentic, unenhanced achievements are valuable for reasons that do not apply to the enhanced achievement, they do not show that the unenhanced approach is, overall, better. Such criticisms merely establish that the two are valued differently. It is still possible that the enhanced achievement may have its own distinctive type of value. As the history shows, the character-building struggles that we admire seem adept at keeping pace with our tools.  Legend has it that Celtic warriors eschewed body armor (and even clothing!) in battle because they thought it diminished the glory of a true victory. Some authors used to insist that keyboards corrupt the writing process.  According to this historical narrative, biomedical enhancements have provided humans with important tools for self-creation that should be embraced (DeGrazia 2000; Agar 2004).
