Abstract
The author travels across the human identity regions, including the social, cultural, philosophical, and biopolitical. First, the author meets the concept of social identity and how it influences an individual's self-concept and body-image. Then a few strokes of the historical and cultural context of human identity, highlighting how technological progress and social structures shape our understanding of identity. By the same token, the author also touches on the ethical dilemmas that may arise from merging body and information technologies, including the possibility of widening income inequality and genetic editing. The philosophical grounds of human identity are then examined, with a focus on the narrative nature of selfhood and the significance of personal identity in bioethics. Finally, the author assesses the impact of public health and biopolitics on identity, including the creation of fictive ethnicities and the challenges of addressing displacement.
