How do we categorize human enhancement? How do we decide that a certain intervention is an enhancement? How do we establish that interventions as diverse as a prosthesis, a drug and a technological support as an implant may all be labelled as enhancements? The essays included in the present issue integrate concrete, empirical examples and try to move forward the discussion on human enhancement based on these examples. By presenting new empirical findings on the topic, these essays examine how these can lead to philosophical problems.
