Perspectives on human regeneration

Regeneration is a concept that has fascinated humans for centuries. Whether we have been trying to bring things back to life, extract additional resources from the world, or remodel our living spaces-domestic and urban-it is often presented as an unproblematic force for good. But what exactly does it mean to regenerate a body, mind or space? This paper, which introduces a collection of contributions on the theme of human regeneration, explores the limits and possibilities of regeneration as a conceptual tool for understanding the biological realm. What does it mean to be regenerated? How can a scholarly focus on this concept enrich our histories of bodies, ageing, disability and science, technology and medicine? As a secondary goal, I identify two distinct aspects of regeneration-'hard' and 'soft' regeneration-which concern the medical and social elements of regeneration respectively. By recognising that everything from cosmetics and fictions to prosthetics and organs grown in vitro display a combination of 'hard' and 'soft' elements, we are better placed to understand that the biological and social must be considered in consort for us to fully appreciate the meanings and practices that underpin multiple forms of human regeneration.
