The document discusses the topic of whether humans can construct superhumans through enhancement technologies. It raises questions about whether such enhancements are technically feasible and morally permissible. Some potential enhancements discussed include increasing height, health span, life span and intelligence through drugs or other medical interventions. However, there are also ethical concerns about such enhancements, such as undermining biological diversity and distorting social order. The document argues that developing principles and oversight for human enhancement will be important issues to address as the technologies advance.
