Human enhancement—the attempt to overcome all human cognitive, emotional, and physical limitations using current technological developments—has been said to pose the most fundamental social and political question facing the world in the twenty-first century. Yet, the public remains ill prepared to deal with it. Indeed, controversy continues to swirl around human enhancement even among the very best-informed experts in the most relevant fields, with no end in sight. Why the ongoing stalemate in the discussion? I attempt to explain the central (...) features of the human enhancement debate and the empirical and normative shortcomings that help to keep it going. I argue that philosophers of science are especially well equipped to rectify these shortcomings, and I suggest that we may be deeply remiss if we don’t do so. (shrink)
