Abstract
Fabiano argues that virtue theory offers the best “safety framework” for mitigating the risks of moral enhancement (1). He advances five desiderata for an ideal safety framework and then explains how virtue theory satisfies each. Among these desiderata is the “preservation of identity” (1). Fabiano argues that moral enhancement can safely preserve personal identity when carried out within the framework of virtue theory. We suggest Fabiano's argument for this conclusion falls short, since contra Fabiano’s claim, enhancing virtues may not preserve—and could even damage—personal identity. We draw on three sources of evidence: 1) virtue theory scholarship that argues for the importance of habituation for virtue formation, 2) Focquaert and Schermer’s (2015) distinction between active and passive enhancement and attendant endorsement of more active paths to virtue enhancement, and 3) empirical research suggesting that technologies which support moral enhancements may have damaging effects on personal identity.
