Losing One's Head or Gaining a New Body?

Area of Science:

• Neuroscience and Philosophy
• Medical Ethics
• Surgical Innovation

Background:

• Quadriplegia presents significant challenges to quality of life, necessitating advanced medical interventions.
• The philosophical debate on personal identity and personhood is central to understanding consciousness and selfhood.
• The HEAVEN surgical head transplant technique is proposed as a radical solution for individuals with severe paralysis.

Purpose of the Study:

• To critically evaluate the philosophical implications of the HEAVEN surgical head transplant.
• To analyze whether the proposed procedure can ensure the ontological survival of the individual's identity.
• To examine the compatibility of HEAVEN with various theories of personhood and personal identity.

Main Methods:

• Philosophical analysis of classical and contemporary theories of personal identity.
• Conceptual examination of personhood in the context of head transplantation.
• Review of ethical considerations surrounding radical surgical interventions.

Main Results:

• The paper identifies philosophical theories that support the preservation of personal identity through head transplantation.
• It also highlights theories that contest the notion of complete ontological survival in such a procedure.
• The analysis reveals a complex interplay between surgical possibility and philosophical definitions of self.

Conclusions:

• The HEAVEN technique raises profound questions about what constitutes personal identity over time and change.
• While promising improved quality of life, its ability to guarantee complete ontological survival remains a subject of philosophical debate.
• Further interdisciplinary discussion is required to reconcile the surgical procedure with established philosophical frameworks of personhood.
