 The hubris objection: This interesting argument holds that the type of attitude that seems to underlie pursuit of such interventions is morally defective in some way, or is indicative of a morally defective character trait. So, for example, Michael Sandel suggests that the attitude underlying the attempt to enhance ourselves is a “Promethean” attitude of mastery that overlooks or underappreciates the “giftedness of human life.” It is the expression and indulgence of a problematic attitude of dominion toward life to which Sandel primarily objects: “The moral problem with enhancement lies less in the perfection it seeks than in the human disposition it expresses and promotes” (Sandel, 2002). Others have pushed back against this tack, arguing that the hubris objection against enhancement is at base a religious one, or that it fundamentally misunderstands the concepts it relies upon (Kahane, 2011).
