Psychiatry, philosophy and the self.

Area of Science:

• Psychology
• Philosophy of Mind
• Neuroscience

Background:

• The concept of personal identity is central to understanding the self.
• Philosophical debates question the substantiality of the narrative self, notably Daniel Dennett's "useful fiction" hypothesis.
• Psychopathology, particularly dissociative identity disorder, offers critical insights into the construction and fragility of personal identity.

Purpose of the Study:

• To investigate psychopathology as a means to illuminate the fundamental nature of personal identity.
• To evaluate the robustness of the narrative self theory against skeptical philosophical viewpoints.
• To explore the utility of an embodied, socially interactive, and autonomous narrative self in resolving complex identity-related paradoxes.

Main Methods:

• A comprehensive review of existing literature on the narrative self and psychopathology.
• Analysis of case studies, focusing on dissociative identity disorder as a limit case.
• Philosophical examination of the concept of personal identity in light of psychological evidence.

Main Results:

• The reviewed literature predominantly supports a more substantial, robust version of the narrative self.
• The narrative self is presented as more than a "useful fiction," possessing inherent unity and continuity.
• Dissociative identity disorder cases illustrate the challenges and importance of an embodied, socially interactive, and autonomous narrative self for personal identity.

Conclusions:

• Psychiatric practice should integrate therapeutic strategies that reinforce the capacity to narrate a coherent life story.
• Restoring the unity of the life narrative is crucial for therapeutic interventions addressing personal identity.
• A robust understanding of the narrative self has implications for legal and moral reasoning concerning personal responsibility and identity.
